Engineering Selection Recommendations

Only substitute parts with matching product status (Active) and confirmed RoHS3 compliance are suitable for applications requiring current environmental certification. BYW85-TAP and equivalents such as 1N5627-TAP and 1N5407G maintain matched RoHS and REACH status. The onsemi 1N5407RLG is not suitable for new designs due to its product status. EGP30K’s compliance certifications are not fully specified. All parts with MSL 1 may be selected for unlimited shelf life requirements.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting the BYW85-TAP diode?
A1: Substitution is determined by voltage rating, average rectified current, forward voltage drop, reverse recovery characteristics, mounting/package compatibility, and regulatory compliance (RoHS, REACH).

Q2: Can I substitute a SOD-64 device with a DO-201AD or DO-27 package?
A2: Substitution by package is possible if the through hole mounting and mechanical clearances are compatible with the circuit board requirements.

Q3: How important are RoHS and REACH statuses in selection?
A3: RoHS and REACH compliance are essential for meeting environmental and regulatory requirements. Only substitute parts with matching compliance should be considered.

Q4: Are differences in recovery time or leakage current significant when choosing substitutes?
A4: Substitution should be based strictly on provided parameters; significant variations in recovery characteristics, as specified, may affect device behavior in sensitive applications.

Q5: Is it necessary to match the operating temperature range exactly?
A5: Operation within or exceeding the specified temperature range is accepted based on the data provided. Lower maximum temperature requires application-specific consideration.

Q6: Can a substitute with higher voltage ratings be used in place of BYW85-TAP?
A6: Higher voltage-rated substitutes in the provided list are compatible, subject to matching other key parameters.
