Equivalent & Substitute Parts for 0ZCD0110FF2C

Part Overview

The 0ZCD0110FF2C is a polymeric PTC resettable fuse manufactured by Bel Fuse Inc., rated for 33V at 1.1A hold current in a 2920 surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. Equivalent parts must maintain the same electrical performance characteristics while meeting current manufacturing and compliance standards.

Key Parameters

Parameter	Value
Voltage - Max	33V
Current - Hold (Ih) (Max)	1.1 A
Current - Trip (It)	2.2 A
Time to Trip	500 ms
Resistance - Initial (Ri) (Min)	90 mOhms
Resistance - Post Trip (R1) (Max)	410 mOhms
Operating Temperature	-40°C ~ 85°C
Mounting Type	Surface Mount
Package / Case	2920 (7351 Metric)

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Voltage rating must equal or exceed 33V maximum
Current hold (Ih) must equal 1.1A
Current trip (It) must equal 2.2A
Time to trip must equal 500 ms
Operating temperature range must encompass -40°C to 85°C
Mounting type must be surface mount
Physical package dimensions must be compatible with 2920 footprint

The substitute parts identified meet these core electrical and mechanical requirements. Variations in maximum current capacity, initial resistance tolerance, and post-trip resistance are permissible within the scope of polymeric PTC fuse technology, provided the hold and trip characteristics remain constant.

Engineering Selection Recommendations

0ZCF0110FF2C (Bel Fuse Inc.) is the primary direct substitute. This part maintains identical electrical specifications and package form factor while offering active product status and ROHS3 compliance. The inclusion of AEC-Q200 qualification provides additional automotive-grade reliability assurance. Packaging is available in Tape & Reel format, supporting automated assembly processes.

MF-SM100-2 (Bourns Inc.) and SMD100F-2 (Littelfuse Inc.) are functional equivalents with the following considerations: both operate at 30V maximum voltage, which is 3V lower than the original specification. Both maintain identical hold current (1.1A), trip current (2.2A), and trip time (500 ms) characteristics. Both are ROHS3 compliant and carry current manufacturing approvals. Package form differs from the original 2920 footprint, requiring PCB layout verification. MF-SM100-2 offers superior moisture sensitivity rating (MSL 1 vs. 2A).

Selection should prioritize 0ZCF0110FF2C for direct replacement applications. Alternative parts are suitable only where circuit voltage margins accommodate the 30V maximum rating and PCB footprint modifications are feasible.

Frequently Asked Questions (FAQ)

Q: Can 0ZCF0110FF2C directly replace 0ZCD0110FF2C without PCB modification?

A: Yes. Both parts share identical electrical specifications (33V, 1.1A hold, 2.2A trip, 500 ms) and the same 2920 package footprint. The primary difference is product status (active vs. obsolete) and compliance certifications. No PCB layout changes are required.

Q: Why do MF-SM100-2 and SMD100F-2 have lower voltage ratings?

A: These parts are rated for 30V maximum, compared to 33V for the original. This 3V difference reflects different polymer formulations and manufacturing processes. Selection depends on actual circuit voltage requirements. If the circuit operates below 30V, these parts are functionally equivalent.

Q: Are package dimensions compatible between 2920 and 2-SMD formats?

A: No. The 2920 package (7.36mm × 5.12mm × 1.00mm) differs from the 2-SMD package (7.31mm × 5.44mm × 3.00mm). While length is similar, width and thickness vary significantly. PCB footprint and component placement must be re-evaluated before substitution.

Q: What is the significance of AEC-Q200 qualification on 0ZCF0110FF2C?

A: AEC-Q200 is an automotive-grade reliability standard. This certification indicates the part meets stringent automotive environmental and performance requirements. It is relevant only if the application requires automotive-grade components.

Q: Do all substitute parts meet the same compliance standards?

A: All substitute parts are ROHS3 compliant and carry TUV approval. 0ZCF0110FF2C adds AEC-Q200 qualification. SMD100F-2 includes CSA and UL approvals. Verify that the selected part's certifications align with your application requirements.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is optimized for high-volume automated assembly. Cut Tape & Digi-Reel packaging supports both manual and automated processes with smaller order quantities. Selection depends on production volume and assembly equipment capabilities.
