Parameter Comparison

Engineering Selection Recommendations

The FEPB16JTHM3/I is a direct substitute for the FEPB16HTHE3_A/I based on the following engineering criteria:

Electrical Compatibility: The FEPB16JTHM3/I meets or exceeds all electrical performance specifications of the original part. The substitute provides higher voltage rating (600 V versus 500 V) and higher current capacity (16 A versus 8 A per diode), ensuring operation within the original design envelope with additional margin.

Package and Mechanical Compatibility: Both components utilize identical TO-263-3 (D2PAK) packaging with two leads and a tab. Surface mount assembly processes, PCB footprints, and thermal management interfaces are directly compatible.

Compliance and Certification: The FEPB16JTHM3/I maintains Automotive grade classification and AEC-Q101 qualification, meeting the same reliability and quality standards as the original part.

Product Availability: The FEPB16HTHE3_A/I is designated Last Time Buy with limited inventory (1047 pieces). The FEPB16JTHM3/I is in Active product status with current inventory (1004 pieces), ensuring long-term availability for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the FEPB16JTHM3/I be used as a direct replacement for the FEPB16HTHE3_A/I without PCB modifications?

A: Yes. Both components share identical TO-263-3 (D2PAK) packaging with two leads and a tab. PCB footprints, land patterns, and mounting interfaces are identical. No PCB redesign is required.

Q: What are the key differences between these two diode arrays?

A: The FEPB16JTHM3/I provides higher electrical ratings: 600 V reverse voltage (versus 500 V) and 16 A average rectified current per diode (versus 8 A). All other electrical characteristics, including forward voltage, recovery time, and leakage current, remain equivalent.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the FEPB16HTHE3_A/I and FEPB16JTHM3/I carry Automotive grade classification and AEC-Q101 qualification, meeting automotive reliability and quality requirements.

Q: Why is the FEPB16HTHE3_A/I marked as Last Time Buy?

A: Last Time Buy designation indicates that the manufacturer has discontinued or will discontinue production of this part number. Existing inventory is available for a limited time. The FEPB16JTHM3/I is recommended for new designs and ongoing production to ensure long-term component availability.

Q: Will the higher current rating of the FEPB16JTHM3/I affect circuit performance?

A: No. The substitute part is rated for higher current capacity (16 A versus 8 A) but operates at identical forward voltage (1.5 V @ 8 A) and recovery time (50 ns). The circuit will function identically within the original design specifications.

Q: Are there any thermal management differences between these parts?

A: Both components use the same TO-263-3 (D2PAK) package with identical thermal interface characteristics. Thermal management and heat dissipation performance are equivalent.

Q: What is the moisture sensitivity level for both parts?

A: The FEPB16HTHE3_A/I specifies Moisture Sensitivity Level (MSL) 1 (Unlimited). This indicates minimal moisture sensitivity and no special handling requirements during storage or assembly.
