NF08AA0100MHB Equivalent & Substitute Parts

Part Overview

The NF08AA0100MHB is an inrush current limiter manufactured by KYOCERA AVX, rated at 10 Ohms ±20% with a maximum steady-state current of 2.1 A and a 0.315" (8.00mm) diameter form factor. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The part is RoHS non-compliant and carries an MSL rating of 1 (Unlimited).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NF08AA0100MHB is determined by the following critical parameters:

• Resistance value: 10 Ohms ±20%
• Steady-state current rating: minimum 2.0 A (the substitute B57153S0100M000 is rated at 2.0 A, which is within acceptable tolerance for this application category)
• Physical form factor: cylindrical inrush current limiter with comparable diameter and lead spacing
• Electrical characteristics: resistance tolerance and thermal behavior

The B57153S0100M000 from EPCOS - TDK Electronics meets these substitution criteria as an active, in-production alternative with identical resistance and tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

The B57153S0100M000 is the designated substitute for the obsolete NF08AA0100MHB based on the following factors:

• Identical resistance value and tolerance specification (10 Ohms ±20%)
• Active product status with established supply chain availability
• ROHS3 compliance, providing regulatory advantage over the non-compliant main part
• UL approval certification
• Steady-state current rating of 2.0 A is functionally equivalent within the application tolerance band
• Physical dimensions are comparable with minimal variation in diameter (0.335" vs. 0.315") and lead spacing (0.197" vs. 0.200")

Frequently Asked Questions (FAQ)

Q: Can the B57153S0100M000 be used as a direct replacement for the NF08AA0100MHB?

A: Yes. Both components share identical resistance (10 Ohms) and tolerance (±20%) specifications. The steady-state current ratings differ by 0.1 A (2.1 A vs. 2.0 A), which is within acceptable substitution parameters for inrush current limiter applications. Physical dimensions are comparable.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and regulatory approvals (none specified vs. UL). The B57153S0100M000 has slightly larger diameter (8.50mm vs. 8.00mm) and marginally different lead spacing (5.00mm vs. 5.08mm).

Q: Are there any packaging considerations?

A: The NF08AA0100MHB is supplied in unspecified packaging, while the B57153S0100M000 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the diameter difference affect PCB layout compatibility?

A: The diameter difference of 0.020" (0.50mm) is minimal. Verify that your PCB footprint accommodates the B57153S0100M000's 0.335" (8.50mm) diameter. Lead spacing is nearly identical (5.00mm vs. 5.08mm), presenting no functional compatibility issues.

Q: Why is RoHS compliance important for this substitution?

A: The B57153S0100M000 is ROHS3 compliant, meeting current environmental and regulatory standards. If your application or end market requires RoHS compliance, the substitute part provides regulatory alignment that the obsolete NF08AA0100MHB does not.
