Substitute Part Grouping Explanation

Substitution of the MF-R700-AP-99 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

• Voltage rating: 30V maximum
• Current hold rating: 7A maximum
• Current trip rating: 14A
• Time to trip: 17.5 seconds
• Initial resistance: 5 mOhms minimum
• Post-trip resistance: 30 mOhms maximum
• Operating temperature range: -40°C to 85°C
• Mounting configuration: Through-hole radial disc
• Physical dimensions: 0.870" L x 0.118" W with 0.402" lead spacing
• RoHS3 compliance

All identified substitutes maintain identical electrical performance and mechanical compatibility with the original MF-R700-AP-99 specification.

Parameter Comparison

Engineering Selection Recommendations

Both MF-R700-AP and MF-R700-AP-14 are direct electrical and mechanical equivalents to the obsolete MF-R700-AP-99. Selection between active substitutes should be based on the following factors:

MF-R700-AP is the primary substitute, maintaining identical specifications and certifications (cURus, TUV) to the original part. This variant is available in Tape & Box packaging with 819 units in current inventory.

MF-R700-AP-14 provides an alternative with expanded regulatory approvals (cUL, cURus, TUV, UL) and AEC-Q200 automotive qualification rating. This variant is also available in Tape & Box packaging with 784 units in current inventory. Selection of MF-R700-AP-14 is appropriate for applications requiring automotive-grade reliability or broader certification scope.

Both substitutes are active products with confirmed stock availability and identical electrical performance across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can MF-R700-AP and MF-R700-AP-14 be used interchangeably with MF-R700-AP-99?

A: Yes. Both active substitutes maintain identical electrical ratings (30V, 7A hold, 14A trip), resistance characteristics, time-to-trip performance, and physical dimensions. They are direct functional equivalents for through-hole radial disc mounting applications.

Q: What is the difference between MF-R700-AP and MF-R700-AP-14?

A: The primary difference is regulatory certification scope. MF-R700-AP-14 includes AEC-Q200 automotive qualification and broader agency approvals (cUL, cURus, TUV, UL) compared to MF-R700-AP (cURus, TUV). Electrical performance and physical specifications are identical.

Q: Are there packaging differences between the substitutes?

A: The MF-R700-AP-99 was supplied in standard packaging. Both active substitutes (MF-R700-AP and MF-R700-AP-14) are available in Tape & Box (TB) packaging format, suitable for automated assembly processes.

Q: Do the substitutes maintain RoHS3 compliance?

A: Yes. Both MF-R700-AP and MF-R700-AP-14 are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of the original MF-R700-AP-99.

Q: Which substitute should be selected for new designs?

A: For standard applications, MF-R700-AP provides direct equivalence. For automotive or applications requiring expanded certifications, MF-R700-AP-14 with AEC-Q200 qualification is the appropriate selection.
