Parameter Comparison

Engineering Selection Recommendations

Both the MF-RHT600-0-14 and 0ZRN0600FF1A are active products with identical electrical performance specifications and mechanical dimensions. Selection between these parts is based on the following factors:

Compliance & Certification Alignment: The MF-RHT600-0-14 carries cUL, cURus, and TUV approvals. The 0ZRN0600FF1A carries cURus, TUV, and UL approvals. Both parts meet AEC-Q200 automotive qualification standards and are ROHS3 compliant. Design requirements specifying particular approval agencies should be cross-referenced with the respective certification portfolios.

Supply Chain & Inventory: Both parts are in active production with current inventory availability. Selection may be driven by supplier relationships, lead time requirements, or regional distribution preferences.

Environmental & Regulatory Compliance: Both parts are REACH unaffected and classified under identical ECCN (EAR99) and HTSUS (8533.40.8070) codes, supporting equivalent regulatory treatment in procurement and export scenarios.

Moisture Sensitivity: The MF-RHT600-0-14 is rated MSL 1 (unlimited). The 0ZRN0600FF1A is rated as not applicable. Both designations indicate minimal moisture sensitivity risk for standard handling and storage.

Frequently Asked Questions (FAQ)

Q: Can the 0ZRN0600FF1A be used as a direct replacement for the MF-RHT600-0-14?

A: Yes. Both parts are polymeric PTC resettable fuses with identical electrical ratings (16V, 6A hold current, 10.8A trip current), identical resistance characteristics, identical operating temperature range, and identical physical dimensions and lead spacing. They are mechanically and electrically interchangeable in through-hole radial disc applications.

Q: Are there differences in approval certifications between these parts?

A: The MF-RHT600-0-14 carries cUL, cURus, and TUV approvals. The 0ZRN0600FF1A carries cURus, TUV, and UL approvals. Both are AEC-Q200 qualified. Design specifications requiring specific approval agencies should be verified against the respective certification lists.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts share identical dimensions: 0.441" L x 0.118" W (11.20mm x 3.00mm), seated height of 0.827" (21.00mm), and lead spacing of 0.201" (5.10mm). They are pin-compatible and occupy identical PCB real estate.

Q: What is the difference in moisture sensitivity rating between these parts?

A: The MF-RHT600-0-14 is rated MSL 1 (unlimited moisture sensitivity level), indicating no moisture-related handling restrictions. The 0ZRN0600FF1A is rated as not applicable, which also indicates minimal moisture sensitivity. Both designations support standard handling and storage without special desiccant or humidity controls.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the MF-RHT600-0-14 and 0ZRN0600FF1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Q: What is the trip current specification for these fuses?

A: Both parts have a trip current (It) of 10.8A with a time to trip of 5 seconds. This means the fuse will transition to a high-resistance state when current exceeds 10.8A for approximately 5 seconds, providing overcurrent protection while allowing brief inrush currents to pass.

Q: Can these fuses be used in automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification, which is the automotive electronics council standard for passive components. This rating confirms suitability for automotive-grade reliability and environmental performance requirements.
