Key Parameters

Substitute Part Grouping Explanation

Substitution of the NF13AA0150M-- is determined by the following critical parameters:

• Resistance value: 15 Ohms (exact match required)
• Tolerance: ±20% (exact match required)
• Current rating: Minimum 2.8 A steady-state capability
• Form factor: Cylindrical inrush current limiter package
• Lead spacing: Compatible with 0.300" (7.62mm) pitch applications

The B57237S0150M000 from EPCOS - TDK Electronics meets these substitution criteria with identical resistance and tolerance specifications, exceeding the current rating requirement at 3 A, and maintaining compatible lead spacing at 0.295" (7.50mm).

Parameter Comparison

Engineering Selection Recommendations

The B57237S0150M000 is the designated manufacturer-recommended substitute for the NF13AA0150M--. Selection of this alternative is supported by:

• Identical electrical specifications (15 Ohms ±20%)
• Superior current rating (3 A vs. 2.8 A)
• Active product status ensuring long-term availability
• ROHS3 compliance for regulatory alignment
• UL approval certification
• Compatible lead spacing within standard PCB design tolerances

The primary design consideration is the increased diameter (15.00mm vs. 13.00mm), which requires verification of available board space in the target application.

Frequently Asked Questions (FAQ)

Q: Can the B57237S0150M000 be used as a direct replacement for the NF13AA0150M--?

A: Yes, provided that the increased diameter of 0.591" (15.00mm) is accommodated within the available PCB footprint. The electrical characteristics and lead spacing are compatible with the original design.

Q: What is the impact of the diameter difference between these parts?

A: The substitute part is 0.079" (2.00mm) larger in diameter. This affects only the physical mounting envelope and does not impact electrical performance. PCB layout must be verified to confirm clearance.

Q: Are there compliance differences between these parts?

A: Yes. The NF13AA0150M-- is RoHS non-compliant, while the B57237S0150M000 is ROHS3 compliant. The substitute also carries UL approval. These differences may be relevant for applications subject to regulatory requirements.

Q: Does the higher current rating of the substitute affect compatibility?

A: No. A higher current rating is a beneficial characteristic that does not compromise compatibility. The substitute can safely handle the original design's 2.8 A requirement.

Q: What is the lead spacing tolerance consideration?

A: Lead spacing differs by 0.005" (0.12mm), which is within standard PCB manufacturing tolerances and does not affect insertion or soldering compatibility.
