Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0ZCF0260FF2C are identified based on strict equivalence of the following critical parameters:

• Voltage rating: 6V maximum
• Hold current (Ih): 2.6 A maximum
• Trip current (It): 5.2 A
• Time to trip: 20 seconds
• Initial resistance (Ri): 20 mOhms minimum
• Post-trip resistance (R1): 75 mOhms maximum
• Operating temperature range: -40°C to 85°C
• Package type: 2920 (7351 Metric), Concave surface mount
• Physical dimensions: 0.290" L x 0.202" W, 0.035" maximum thickness
• RoHS3 compliance

The FSMD260-2920-R from RFE/Fuzetec meets all specified electrical and mechanical parameters, establishing it as a parametric equivalent for direct substitution in applications requiring polymeric PTC resettable fuse protection at 6V, 2.6 A hold current.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ZCF0260FF2C and FSMD260-2920-R are active production components with ROHS3 compliance. The 0ZCF0260FF2C carries AEC-Q200, cURus, and TUV approvals. The FSMD260-2920-R carries cUL, TUV, and UL approvals. Selection between these parts should be based on specific application certification requirements and supply chain availability. Both components are suitable for surface mount assembly in 2920 package footprints where 6V, 2.6 A hold current protection is required.

Frequently Asked Questions (FAQ)

Q: Can FSMD260-2920-R be used as a direct replacement for 0ZCF0260FF2C?

A: Yes. Both parts share identical electrical specifications (6V, 2.6 A hold current, 5.2 A trip current, 20 mOhms initial resistance, 75 mOhms post-trip resistance) and mechanical compatibility (2920 package, 0.290" x 0.202" x 0.035" maximum dimensions). Surface mount assembly processes are identical.

Q: What are the key parameters that determine substitution eligibility?

A: Voltage rating (6V), hold current (2.6 A), trip current (5.2 A), time to trip (20 s), initial and post-trip resistance values, operating temperature range (-40°C to 85°C), and 2920 package dimensions must all match exactly.

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

A: The 0ZCF0260FF2C includes AEC-Q200 certification in addition to cURus and TUV. The FSMD260-2920-R includes cUL and UL certifications in addition to TUV. Application-specific certification requirements should guide selection.

Q: What is the moisture sensitivity level difference?

A: The 0ZCF0260FF2C is rated MSL 2A (4 weeks), while FSMD260-2920-R is rated MSL 2 (1 year). Both are MSL 2 classification; the extended storage window for FSMD260-2920-R may provide supply chain advantages.

Q: Are the physical footprints identical?

A: Yes. Both components use the 2920 (7351 Metric) concave surface mount package with identical dimensions: 0.290" length, 0.202" width, and 0.035" maximum thickness. PCB footprints are interchangeable.
