Engineering Selection Recommendations

All substitute parts listed maintain Active product status and are RoHS3 compliant. Selection among equivalent options is based on compliance certifications and operational requirements:

Eaton - Electronics Division Options (S500-160-R, BK/S500-160-R, GDB-160MA): These parts share identical electrical and mechanical specifications with the main part. BK/S500-160-R and GDB-160MA provide alternative sourcing from the same manufacturer with equivalent performance characteristics.

Littelfuse Inc. Options (0217.160MXP, 0217.160HXP): Both parts meet all mandatory substitution criteria and carry comprehensive international certifications including UL, CSA, and VDE. Operating temperature range extends to -55°C ~ 125°C. These parts are suitable for applications requiring extended temperature performance.

SCHURTER Inc. Option (0034.1508): This part satisfies all mandatory electrical and mechanical requirements with operating temperature range of -55°C ~ 125°C. Certifications include CCC, cURus, and VDE.

OptiFuse Options (FSC-160MA, FSD-160MA): Both parts meet mandatory substitution criteria. FSC-160MA features a higher breaking capacity of 100A compared to the standard 35A. FSD-160MA maintains 35A breaking capacity with Melting I²t of 0.0099, closely aligned with the main part specification.

Frequently Asked Questions (FAQ)

Q: What determines if a fuse can substitute for the S500-160-R?

A: Substitution requires matching of current rating (160 mA), voltage rating (250 V AC), fuse type (Cartridge, Glass), response time (Fast Blow), and package dimensions (5mm x 20mm). All listed parts meet these mandatory criteria.

Q: Are there differences in breaking capacity among the substitute parts?

A: Yes. Most substitute parts maintain 35A breaking capacity at rated voltage, matching the main part. The FSC-160MA variant features 100A breaking capacity. Breaking capacity does not affect substitution eligibility when primary electrical specifications match.

Q: What is the significance of DC Cold Resistance variations?

A: DC Cold Resistance values vary among manufacturers (ranging from 2.525 Ohms to 9.1 Ohms) but do not affect substitution compatibility. This parameter reflects manufacturing design differences and does not impact circuit protection performance at the specified current and voltage ratings.

Q: Do all substitute parts carry the same international certifications?

A: No. Certification coverage varies by manufacturer. The main part S500-160-R carries BSI, CCC, CSA, cURus, IMQ, SEMKO, and VDE approvals. Littelfuse parts include UL certification. Verify specific certifications required for your application before selection.

Q: Can I use FSC-160MA with its higher 100A breaking capacity as a direct substitute?

A: Yes. FSC-160MA meets all mandatory electrical and mechanical substitution criteria. The higher breaking capacity provides additional margin and does not create incompatibility. Application requirements determine whether this enhanced specification is beneficial.

Q: What is the difference between 0217.160MXP and 0217.160HXP?

A: Both Littelfuse parts are electrically and mechanically identical with matching current ratings, voltage ratings, and package dimensions. Both carry identical certifications and operating temperature ranges. Selection between these variants depends on availability and supply chain requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant. The main part S500-160-R is also RoHS3 compliant, ensuring environmental compliance across all options.

Q: What operating temperature ranges are available?

A: The main part S500-160-R does not specify an operating temperature range. Littelfuse (0217.160MXP, 0217.160HXP), SCHURTER (0034.1508), and OptiFuse FSD-160MA all specify -55°C ~ 125°C. OptiFuse FSC-160MA specifies -55°C ~ 90°C. Select based on application temperature requirements.
