Engineering Selection Recommendations
Both RFN2LAM6STR and RFN2LAM6STFTR are active products, comply with ROHS3, and are unaffected by REACH regulations. Each part meets the same electrical and mechanical parameters. For applications requiring automotive-grade qualification and AEC-Q101 compliance, RFN2LAM6STFTR provides an alternative within the same specification group. Selection may be guided by inventory level and formal qualification requirements.
Frequently Asked Questions (FAQ)
Q: What are the critical criteria for substituting RFN2LAM6STR in a circuit?
A: Substitution is determined based on maximum reverse voltage, average rectified current, forward voltage at rated current, reverse recovery time, reverse leakage, speed classification, mounting type, package/case, and compliance status.
Q: Are RFN2LAM6STR and RFN2LAM6STFTR mechanically compatible?
A: Both diodes use identical mounting types (Surface Mount), package/case (SOD-128), and supplier device packages (PMDTM), ensuring direct mechanical compatibility.
Q: Is there any difference in electrical performance between RFN2LAM6STR and its substitute RFN2LAM6STFTR?
A: All relevant electrical parameters provided (Vr, Io, Vf, trr, reverse leakage, and speed) are equivalent.
Q: When should RFN2LAM6STFTR be selected as a substitute?
A: RFN2LAM6STFTR can be selected based on inventory status or required automotive/AEC-Q101 qualification, as long as all key parameters match the application requirements.
Q: Do both parts comply with environmental and regulatory standards?
A: Both RFN2LAM6STR and RFN2LAM6STFTR are ROHS3 compliant, REACH unaffected, and have the same moisture sensitivity level (MSL 1 Unlimited).
