Key Parameters

Substitute Part Grouping Explanation

Substitute diode candidates are grouped strictly by matching parameters: category, voltage rating, current rating, forward voltage drop at test current, fast recovery designation, reverse recovery performance, maximum reverse leakage, mounting type, package, and junction temperature range. Only devices showing identical or compatible parameter values and regulatory compliance fall within substitution scope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active and comply with ROHS3 environmental standards. The ES3JB-HF and ES3JB models match all provided key electrical and mechanical parameters, series, packaging format, and regulatory classifications. REACH status is unaffected for all substitute part numbers provided where specified. Inventory levels are sufficient for each part. Selection between these parts can be based solely on part availability, stock levels, and required compliance certificates.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting US3JB-HF with ES3JB-HF or ES3JB?
A: Substitution is based strictly on DC reverse voltage rating, average rectified current, forward voltage drop at test current, reverse recovery time, leakage current at reverse voltage, mounting type, package/case, and operating junction temperature.

Q: Are all substitute parts in the same package/case as US3JB-HF?
A: Yes, all substitute part numbers are offered in the DO-214AA (SMB) surface-mount package.

Q: Do substitute diodes have the same RoHS environmental compliance as US3JB-HF?
A: Yes, the substitute parts specified are ROHS3 compliant.

Q: Is the reverse recovery time identical on all substitutes?
A: The ES3JB-HF and ES3JB parts feature a reverse recovery time of 35 ns, whereas US3JB-HF is rated at 75 ns.

Q: Are there differences in inventory availability among the substitutes?
A: Yes, inventory quantities vary; ES3JB-HF and ES3JB have substantially higher stock levels compared to US3JB-HF.

Q: Are there series or supplier differences in the substitute list?
A: ES3JB-HF and US3JB-HF are from Comchip Technology. ES3JB is from MDD. All are in the Diodes, Rectifiers category with matching parameters for substitution.
