【出品の経緯】
自分のNA8ロードスター(シリーズ1.5)のECUに液漏れが発生しました。同じ症状で悩んでいる方も多いと思い、どうせ交換するなら純正品より少しでも良いものをと思い、耐圧や耐熱・用途などを確認しながら部品を選びました。購入した部品が余りましたので、同じ悩みをお持ちの方のお役に立てればと思い出品します。部品を個別に探す手間が省ければ幸いです。在庫がなくなったら再販はする予定はありません。

【対象車種】
NA8Cロードスター(シリーズ1 / シリーズ1.5)ECU BPF3

【内容物】
電解コンデンサ 3種 各1個(計3個)
写真の赤丸の部品になります。
※いずれも国産メーカーの新品です。

【純正品との比較】
純正品は製造から30年以上が経過しており、経年劣化による液漏れが各所で報告されています。本セットは純正品と同じ容量・耐熱を維持しつつ、以下の点でスペックアップした部品を選んでいます。

● 220μF(液漏れが最も起きやすい部品)
純正品:10V耐圧
本セット:25V耐圧(純正比2.5倍)
→ 耐圧に余裕を持たせることで電解液への負担を減らし、液漏れリスクを低減

● 33μF(次に液漏れが起きやすい部品)
純正品:35V耐圧
本セット:50V耐圧(純正比1.4倍)・自動車電装品用途対応品
→ 耐圧余裕を高め、車載用途向けとして明示されている部品を選定

● 47μF(液漏れの実績がほぼない部品)
純正品:63V耐圧
本セット:63V耐圧(同等)・高リップル電流対応品
→ 耐圧は同等ながらサージ耐性を強化した部品を選定

【共通スペック】
・全品105℃耐熱(車載用途の必須条件をクリア)
・全品国産メーカー新品
・全品で純正品と同等以上のスペックを確保

【こんな方におすすめ】
・NA8 ECUの液漏れ・不調を自分で修理したい方
・せっかく交換するなら少しでも良い部品を使いたい方
・部品選定の手間を省きたい方

【すでに液漏れが起きている方へ】
すでに液漏れが発生して困っている方に少しでもお役に立てればと思い、作業時の注意点をまとめておきます。

基板の変色について
液漏れによる黒ずみ・変色が見られる場合、表面を洗浄するだけでは不十分な場合があります。電解液は強アルカリ性で、時間が経つにつれて基板内部まで浸透し、配線パターン(銅箔)の腐食が進行していることがあります。
本来は奥まで腐食が及んでいる場合は基板ごと交換するのが最も確実ですが、なかなかそうもいかないのが現実です。自分の場合もこのケースです。

最小限の費用で改善する場合の注意点
コンデンサを交換するだけでなく、以下の手順を踏むことで信頼性が低減するのを最小限に留めます。
1.コンデンサ取り外し後、基板表面を高純度IPA(99%以上)で丁寧に洗浄する
→ 液漏れの残留物を丸ごと除去することで領域間のリーク電流を防ぐ
2.変色箇所の配線パターンをテスターで導通チェックする
→ 断線や将来断線の可能性があれば細いジャンパー線でに修復する
3.スルーホール内部の腐食を確認する
→ 内壁まで腐食が及んでいる場合ははんだを多めに流して内壁を補強するように充填する
4.十分に乾燥後にコンデンサを取り付け通電確認を行う
※ここまでで改善しないのであれば苦渋の判断になりますが、液漏れのない中古ECUの入手や専門業者への依頼も選択肢の一つとして検討するのが現実的だと思います。

【注意事項】
・取り付けは自己責任でお願いします。
・新品未使用品です。
・返品・保証はお受けできません。
・作業には基礎的な電子工作の知識が必要です。

液漏れの頻度を記載している部分に誤りがある事に気付きましたので訂正します。
最も液漏れ頻度が高いのは47μ、次に220μ、最後が33μです。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters).

3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
