Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FPAM50LH60 is determined by the following critical parameters:

• Configuration: Must maintain 2-phase IGBT architecture
• Current Rating: Must support minimum 50A continuous current
• Voltage Rating: Must support minimum 600V operation
• Voltage Isolation: Must maintain 2500Vrms isolation specification
• Package Type: Must use 32-PowerDIP Module form factor with identical mechanical dimensions (1.370", 34.80mm)
• Mounting Type: Must support through-hole mounting compatibility

The NFL25065L4BT meets all substitution criteria while offering enhanced voltage capability at 650V, providing additional design margin for the same current and isolation specifications.

Parameter Comparison

Engineering Selection Recommendations

The NFL25065L4BT is the manufacturer-recommended substitute for the obsolete FPAM50LH60. Both components maintain identical mechanical and electrical compatibility across all critical parameters: 2-phase configuration, 50A current capacity, 2500Vrms isolation, and 32-PowerDIP through-hole package format.

The NFL25065L4BT offers an increased voltage rating of 650V compared to the original 600V specification, providing additional operational margin without compromising any other electrical or mechanical characteristics. Both parts maintain ROHS3 compliance and equivalent regulatory status.

The substitute part is currently in active production status with confirmed inventory availability, ensuring long-term supply chain continuity for replacement and new applications.

Frequently Asked Questions (FAQ)

Q: Can the NFL25065L4BT be used as a direct replacement for the FPAM50LH60?

A: Yes. The NFL25065L4BT is the manufacturer-recommended substitute. Both parts share identical package dimensions, mounting type, current rating, isolation voltage, and 2-phase configuration. The substitute operates at 650V versus the original 600V, providing additional voltage margin.

Q: Are there any mechanical compatibility concerns with the NFL25065L4BT?

A: No. Both the FPAM50LH60 and NFL25065L4BT use the 32-PowerDIP Module package with identical dimensions of 1.370" (34.80mm). Through-hole mounting compatibility is maintained.

Q: What is the primary difference between these two parts?

A: The NFL25065L4BT operates at 650V maximum voltage compared to the FPAM50LH60 at 600V. All other electrical specifications—current rating, isolation voltage, configuration, and package format—remain identical.

Q: Why is the FPAM50LH60 listed as obsolete?

A: The FPAM50LH60 has been discontinued by the manufacturer. The NFL25065L4BT represents the current active product line replacement with equivalent functionality and enhanced voltage capability.

Q: Are both parts RoHS compliant?

A: Yes. Both the FPAM50LH60 and NFL25065L4BT maintain ROHS3 compliance status.
