Engineering Selection Recommendations

Both the SS2PH9HM3_A/I and SS2PH9HM3_A/H are suitable for direct substitution in applications requiring a 29 V, 2 A Schottky rectifier diode in DO-220AA surface mount packaging. Selection between these parts should be based on inventory availability and procurement lead times, as they are parametrically identical.

The SS2PH9HM3_A/H offers higher inventory availability (8878 pieces in stock) compared to the SS2PH9HM3_A/I (647 pieces in stock), making it the preferred choice for immediate procurement requirements.

Both parts maintain active production status and full compliance with automotive qualification standards (AEC-Q101) and environmental regulations (ROHS3 Compliant, REACH Unaffected). No performance differentiation exists between these devices.

Frequently Asked Questions (FAQ)

Q: Can SS2PH9HM3_A/H be used as a direct replacement for SS2PH9HM3_A/I?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (voltage, current, forward drop, leakage, capacitance) and mechanical characteristics (package, mounting type, temperature range). They are interchangeable without circuit modification.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both parts carry identical automotive grade classification and AEC-Q101 qualification. They meet the same regulatory and performance standards for automotive applications.

Q: What is the significance of the different part number suffixes (_A/I versus _A/H)?

A: The suffix variation indicates different manufacturing tape reels or packaging configurations from Vishay. The electrical and functional specifications remain identical. The suffix does not affect circuit performance or compatibility.

Q: Do both parts have the same environmental compliance status?

A: Yes. Both SS2PH9HM3_A/I and SS2PH9HM3_A/H are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations.

Q: Is the DO-220AA package identical for both parts?

A: Yes. Both parts use the DO-220AA (SMP) surface mount package with identical footprint, lead configuration, and mounting requirements.

Q: What is the operating temperature range for both parts?

A: Both parts operate across a junction temperature range of -55°C to 175°C, providing identical thermal performance specifications.
