Substitute Part Grouping Explanation

Substitution of the SS3P3LHM3_A/I is determined by equivalence in the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 3 A
• Technology: Schottky
• Speed classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Compliance Criteria:

• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The PMEG030V030EPDZ from Nexperia USA Inc. meets all substitution criteria. Both devices operate at identical voltage and current ratings, employ Schottky technology with fast recovery characteristics, carry automotive qualification, and are housed in compatible TO-277 surface mount packages. Both components are RoHS3 compliant with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both the SS3P3LHM3_A/I and PMEG030V030EPDZ are active production components with identical electrical ratings and automotive qualification status. Selection between these parts is based on the following factors:

Electrical Performance: The PMEG030V030EPDZ exhibits lower forward voltage (450 mV vs. 470 mV at 3 A) and lower reverse leakage current (150 µA vs. 250 µA at 30 V), resulting in reduced power dissipation and improved efficiency in rectification applications.

Thermal Capability: The PMEG030V030EPDZ supports a maximum junction temperature of 175°C, compared to 150°C for the SS3P3LHM3_A/I, providing additional thermal margin in high-temperature operating environments.

Compliance & Qualification: Both components carry AEC-Q101 automotive qualification, ROHS3 compliance, and MSL 1 rating, confirming suitability for automotive and industrial applications without additional qualification requirements.

Package Compatibility: Both devices use TO-277 surface mount packages with 3-PowerDFN case designation. Physical footprint and pin configuration are compatible for direct substitution on existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the PMEG030V030EPDZ directly replace the SS3P3LHM3_A/I on a PCB?

A: Yes. Both components use identical TO-277, 3-PowerDFN package designations with compatible pin configurations and physical footprints. Direct substitution on existing PCB layouts is supported without layout modifications.

Q: What are the key electrical differences between these two parts?

A: The PMEG030V030EPDZ provides lower forward voltage (450 mV vs. 470 mV at 3 A) and lower reverse leakage current (150 µA vs. 250 µA at 30 V). Both devices maintain identical 30 V reverse voltage and 3 A current ratings with fast recovery Schottky characteristics.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the SS3P3LHM3_A/I and PMEG030V030EPDZ carry automotive-grade classification with AEC-Q101 qualification, confirming compliance with automotive reliability and quality standards.

Q: What is the difference between the supplier device packages listed (TO-277A SMPC vs. CFP15)?

A: Both designations refer to the same physical TO-277, 3-PowerDFN package form factor. The different naming conventions reflect manufacturer-specific package nomenclature while maintaining mechanical and electrical compatibility.

Q: Which part should be selected for high-temperature applications?

A: The PMEG030V030EPDZ supports a maximum junction temperature of 175°C, compared to 150°C for the SS3P3LHM3_A/I. For applications operating near or above 150°C, the PMEG030V030EPDZ provides additional thermal headroom.

Q: Do both parts meet RoHS and moisture sensitivity requirements?

A: Yes. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.

Q: Are there any performance trade-offs when substituting between these parts?

A: No trade-offs exist. The PMEG030V030EPDZ provides equivalent or superior electrical performance with lower power dissipation and higher thermal capability while maintaining full compatibility with the SS3P3LHM3_A/I in all specified electrical and mechanical parameters.
