Engineering Selection Recommendations

Both MF-R160-AP and MF-R160-AP-17 are direct parametric equivalents to the obsolete MF-R160-AP-99. Selection between active alternatives is based on compliance and certification requirements:

MF-R160-AP is suitable for applications requiring cURus and TUV certifications. This part maintains the same electrical and mechanical specifications as the original.

MF-R160-AP-17 provides expanded regulatory coverage with cUL, cURus, TUV, and UL approvals, plus AEC-Q200 automotive qualification. This part is recommended for applications requiring automotive-grade reliability or broader regulatory acceptance.

Both substitute parts are available in Tape & Box packaging and carry ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can MF-R160-AP and MF-R160-AP-17 be used interchangeably with MF-R160-AP-99?

A: Yes. All three parts share identical electrical parameters (30V, 1.6A hold current, 3.2A trip current, 8-second trip time) and mechanical specifications (radial disc configuration, 0.402" diameter, 0.201" lead spacing). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between MF-R160-AP and MF-R160-AP-17?

A: The primary differences are product status and certifications. MF-R160-AP is an active part with cURus and TUV approvals. MF-R160-AP-17 is also active and includes additional certifications (cUL, UL) plus AEC-Q200 automotive qualification. Both maintain identical electrical and physical characteristics.

Q: Why is MF-R160-AP-99 listed as obsolete?

A: The original part number has been superseded by active alternatives. MF-R160-AP and MF-R160-AP-17 provide equivalent functionality with improved availability and expanded certification coverage.

Q: Does packaging differ between these parts?

A: The original MF-R160-AP-99 packaging is listed as unspecified. Both active substitutes (MF-R160-AP and MF-R160-AP-17) are supplied in Tape & Box (TB) packaging, which is standard for through-hole component distribution.

Q: Are there any compliance or regulatory differences?

A: All three parts are ROHS3 compliant and REACH unaffected. MF-R160-AP-17 carries additional regulatory approvals (cUL, UL) and AEC-Q200 automotive qualification compared to MF-R160-AP. Selection depends on specific application requirements.

Q: What inventory status should I expect?

A: MF-R160-AP-99 (obsolete) has 776 pieces in stock. MF-R160-AP has 1055 pieces available. MF-R160-AP-17 has 1002 pieces available. Both active alternatives offer adequate supply for procurement.
