Key Parameters

Substitute Part Grouping Explanation

The B57237S0100M000 qualifies as a direct substitute based on the following critical parameters:

• Resistance value: 10 Ohms (identical)
• Tolerance: ±20% (identical)
• Steady-state current rating: 3.7 A (identical)
• Physical diameter: 0.591" (15.00mm) (identical)
• Lead spacing: 0.295" (7.50mm) (functionally compatible, within typical PCB tolerance)
• Moisture sensitivity: MSL 1 (identical)
• HTSUS classification: 8533.40.8070 (identical)

The substitute maintains all critical electrical and mechanical parameters required for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The B57237S0100M000 is the designated manufacturer-recommended substitute for the obsolete NF15AA0100M--. Selection of this alternative provides:

• Active product status with ongoing manufacturer support and availability
• ROHS3 compliance, addressing regulatory requirements for new designs
• UL approval certification, supporting applications requiring third-party validation
• Identical electrical performance across all critical parameters
• Functionally compatible mechanical form factor with negligible lead spacing variance

For applications subject to RoHS compliance mandates, the B57237S0100M000 is the appropriate selection. For legacy systems where RoHS non-compliance is acceptable, the original specification remains valid where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the B57237S0100M000 be used as a direct replacement for NF15AA0100M-- in existing designs?

A: Yes. The substitute maintains identical resistance, tolerance, current rating, and physical diameter. Lead spacing differs by 0.005" (0.12mm), which is within standard PCB layout tolerances and does not affect electrical performance or mechanical fit.

Q: What is the primary reason for substitution?

A: The NF15AA0100M-- is obsolete. The B57237S0100M000 provides equivalent functionality with active product status and improved compliance certifications.

Q: Are there compliance differences between these parts?

A: Yes. The B57237S0100M000 is ROHS3 compliant and carries UL approval, while the NF15AA0100M-- is RoHS non-compliant with no listed approval agency. New designs should specify the B57237S0100M000 to meet current regulatory requirements.

Q: Is the lead spacing difference significant?

A: No. The 0.005" (0.12mm) difference in lead spacing is negligible for standard PCB design and does not impact electrical characteristics or mechanical reliability.

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

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
