Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0ZCD0260FF2C is determined by strict alignment of electrical and mechanical parameters. The critical substitution criteria are:

Electrical Parameters (Must Match):

• Voltage rating: 6V maximum
• Current hold (Ih): 2.6A maximum
• Resistance initial (Ri): 20 mOhms minimum
• Resistance post-trip (R1): 75 mOhms maximum
• Operating temperature range: -40°C to 85°C

Mechanical Parameters (Must Match):

• Package type: 2920 (7351 Metric) surface mount
• Physical dimensions: 0.290" L x 0.202" W (7.36mm x 5.12mm)
• Mounting: Surface mount

Acceptable Variations:

• Current trip (It) values within the 5.0A to 5.2A range are acceptable
• Current maximum (Imax) may vary provided it does not reduce circuit protection capability
• Time to trip variations are acceptable within normal operating margins
• Packaging format (bulk vs. tape & reel) does not affect electrical substitution
• Concave vs. standard form factor does not affect electrical substitution

The identified substitute parts meet these criteria while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

0ZCF0260FF2C (Bel Fuse Inc.): This substitute maintains identical electrical specifications to the main part while offering active product status. It includes AEC-Q200 automotive qualification in addition to cURus and TUV approvals, and is RoHS3 compliant. The concave form factor and higher current maximum rating (100A vs. 40A) provide enhanced design flexibility. This part is the direct successor within the Bel Fuse product line.

2920L260PR (Littelfuse Inc.): This substitute provides cross-manufacturer compatibility with matching voltage, hold current, and resistance specifications. The POLY-FUSE® series designation indicates established market presence. Time to trip is reduced to 10 seconds compared to 20 seconds in the main part, and initial resistance is slightly higher at 25 mOhms minimum. Thickness is increased to 0.049" (1.25mm). This part is suitable for applications where faster response time is acceptable or beneficial. RoHS3 compliance and active product status are confirmed.

Both substitutes maintain the required 6V rating, 2.6A hold current, and 2920 surface mount package. Selection between them depends on specific application requirements regarding response time and form factor constraints.

Frequently Asked Questions (FAQ)

Q: Can 0ZCF0260FF2C be used as a direct replacement for 0ZCD0260FF2C?

A: Yes. The 0ZCF0260FF2C maintains identical voltage (6V), hold current (2.6A), trip current (5.2A), and resistance specifications. Both use the 2920 surface mount package with matching physical dimensions. The primary difference is product status (active vs. obsolete) and the addition of AEC-Q200 qualification in the substitute.

Q: What is the significance of the concave form factor in 0ZCF0260FF2C?

A: The concave form factor is a mechanical variation that does not affect electrical performance. It may influence PCB layout and component placement but does not impact substitution compatibility for electrical circuit function.

Q: How does the 2920L260PR differ in performance from the main part?

A: The 2920L260PR has a faster time to trip (10 seconds vs. 20 seconds) and slightly higher initial resistance (25 mOhms minimum vs. 20 mOhms minimum). These differences may affect circuit response characteristics in time-sensitive applications. The increased thickness (0.049" vs. 0.035") requires verification of PCB assembly clearance.

Q: Are all three parts RoHS compliant?

A: The 0ZCF0260FF2C and 2920L260PR are confirmed RoHS3 compliant. The main part 0ZCD0260FF2C does not specify RoHS status in the provided data.

Q: What packaging formats are available for these parts?

A: The 0ZCD0260FF2C is available in bulk packaging. The 0ZCF0260FF2C and 2920L260PR are supplied in tape & reel (TR) format. Packaging format does not affect electrical substitution; format selection is determined by procurement and assembly requirements.

Q: Do these parts have identical approval certifications?

A: All three parts carry cURus and TUV approvals. The 0ZCF0260FF2C additionally includes AEC-Q200 automotive qualification. The 0ZCD0260FF2C does not list AEC-Q200 certification.

Q: Can thickness variation affect PCB assembly?

A: Yes. The 2920L260PR has a maximum thickness of 0.049" (1.25mm) compared to 0.035" (0.90mm) for the main part and 0ZCF0260FF2C. PCB layout, solder reflow profiles, and component placement must accommodate this increased height. Verification with assembly documentation is required before substitution.
