Key Parameters

Substitute Part Grouping Explanation

Substitution of the FSAM75SM60A is determined by the following critical parameters:

• Current Rating: 75 A (exact match required)
• Voltage Isolation: 2500Vrms (exact match required)
• Configuration: 3 Phase (exact match required)
• Mounting Type: Through Hole (exact match required)
• RoHS Compliance: ROHS3 Compliant (maintained)

The NFAL7565L4B meets these core substitution criteria. While the voltage rating increases from 600V to 650V and the package transitions from 32-PowerDIP to 30-PowerDIP, these parameters remain within acceptable substitution boundaries for equivalent functionality. The higher voltage rating provides additional design margin. The package change requires mechanical verification for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The NFAL7565L4B is the designated substitute for the obsolete FSAM75SM60A. Selection is supported by:

• Active product status ensuring continued availability and supply chain stability
• Identical current rating (75A) and isolation voltage (2500Vrms)
• ROHS3 compliance maintained across both products
• Higher voltage rating (650V vs 600V) provides additional operational margin
• Through-hole mounting compatibility with existing PCB infrastructure

The package transition from 32-PowerDIP to 30-PowerDIP requires mechanical layout verification to confirm pin-to-pin compatibility and PCB footprint accommodation.

Frequently Asked Questions (FAQ)

Q: Can the NFAL7565L4B directly replace the FSAM75SM60A without circuit modification?

A: The NFAL7565L4B maintains identical current and isolation voltage ratings. The higher voltage rating (650V vs 600V) is compatible with 600V-rated circuits. Pin configuration differences between 32-PowerDIP and 30-PowerDIP packages require PCB layout verification.

Q: What is the significance of the voltage rating increase from 600V to 650V?

A: The 650V rating of the NFAL7565L4B provides additional voltage margin above the 600V specification of the FSAM75SM60A. This does not compromise compatibility in 600V applications.

Q: Are there differences in isolation voltage between these parts?

A: Both parts maintain 2500Vrms isolation voltage. This parameter is identical and does not affect substitution feasibility.

Q: What packaging differences exist between these modules?

A: The FSAM75SM60A uses 32-PowerDIP packaging (1.370", 34.80mm), while the NFAL7565L4B uses 30-PowerDIP packaging (1.385", 35.17mm). Physical dimensions are similar but pin count differs. PCB footprint compatibility must be confirmed during design integration.

Q: Are both parts RoHS compliant?

A: Yes. Both the FSAM75SM60A and NFAL7565L4B are ROHS3 compliant, ensuring regulatory alignment for applications requiring RoHS certification.

Q: What is the product status difference and why does it matter?

A: The FSAM75SM60A is obsolete, limiting future availability. The NFAL7565L4B is active, ensuring continued supply and support for new designs and production runs.
