Polymeric PTC Resettable Fuse 0ZCC0075FF2C Equivalent & Substitute Parts

Part Overview

The 0ZCC0075FF2C is a polymeric PTC resettable fuse manufactured by Bel Fuse Inc., rated for 16V at 750 mA hold current in a 1812 (4532 Metric) surface mount package. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The device provides overcurrent protection with automatic recovery characteristics typical of polymeric PTC technology.

Substitute Part Grouping Explanation

Substitution eligibility for the 0ZCC0075FF2C is determined by the following critical parameters:

Voltage rating must equal or exceed 16V maximum
Current hold (Ih) must be 750 mA
Current trip (It) must be 1.5 A
Package must be 1812 (4532 Metric) surface mount
Operating temperature range must cover -40°C ~ 85°C
Time to trip must be 200 ms
Resistance characteristics (Ri and R1) must fall within specified ranges

Parts with lower voltage ratings (13.2V) are listed as similar alternatives but do not meet the full voltage requirement of the original specification. The 0ZCG0075FF2C from Bel Fuse Inc. qualifies as a direct substitute with identical electrical parameters and improved product status (active vs. obsolete).

Engineering Selection Recommendations

Direct Substitute (Recommended): The 0ZCG0075FF2C from Bel Fuse Inc. is the primary substitute for the obsolete 0ZCC0075FF2C. Both parts share identical electrical specifications (16V, 750 mA hold current) and package dimensions. The 0ZCG0075FF2C offers active product status, AEC-Q200 automotive qualification, and ROHS3 compliance, making it suitable for new designs and production continuity.

Alternative Substitutes (Voltage Derating Required): The MF-MSMF075-2 (Bourns), PTS181213V075 (Eaton), 1812L075PR (Littelfuse), and MINISMDC075F-2 (Littelfuse) all operate at 13.2V maximum voltage. These parts are functionally equivalent in terms of hold current, trip current, and package form factor but operate at a reduced voltage rating. Selection of these alternatives requires circuit design verification to confirm that 13.2V operation is acceptable for the intended application. All alternatives maintain active product status and ROHS3 compliance.

Compliance Considerations: All substitute parts carry cURus and TUV approvals. The 0ZCG0075FF2C and MF-MSMF075-2 include AEC-Q200 automotive qualification. The MINISMDC075F-2 includes CSA and UL approvals in addition to TUV certification.

Frequently Asked Questions (FAQ)

Q: Can I use a 13.2V rated part in place of the 16V 0ZCC0075FF2C? A: Only if your circuit design operates at or below 13.2V. The substitute parts with 13.2V ratings (MF-MSMF075-2, PTS181213V075, 1812L075PR, MINISMDC075F-2) are not direct replacements for 16V applications. Circuit verification is required before substitution.

Q: What is the difference between the 0ZCC0075FF2C and 0ZCG0075FF2C? A: Both parts share identical electrical specifications and package dimensions. The primary differences are product status (0ZCC is obsolete; 0ZCG is active), packaging format (0ZCG is supplied in Tape & Reel), and certifications (0ZCG includes AEC-Q200). The 0ZCG0075FF2C is the recommended replacement.

Q: Are all substitute parts in the same 1812 package? A: Yes, all listed substitutes use the 1812 (4532 Metric) surface mount package. Some variants include a concave top surface, which does not affect electrical performance or PCB mounting compatibility.

Q: What certifications should I verify for my application? A: Verify that the selected substitute meets your application's certification requirements. The 0ZCG0075FF2C includes AEC-Q200 for automotive use. The MINISMDC075F-2 includes CSA and UL approvals. All parts carry cURus and TUV certifications.

Q: Do all substitutes have the same resistance characteristics? A: Initial resistance (Ri) and post-trip resistance (R1) are consistent across all parts, with one exception: the 1812L075PR has a minimum initial resistance of 100 mOhms compared to 110 mOhms for other parts. This difference is within acceptable tolerance for most applications.

Q: What is the moisture sensitivity level (MSL) for these parts? A: The 0ZCC0075FF2C and MINISMDC075F-2 are rated MSL 2A (4 weeks). The 0ZCG0075FF2C, MF-MSMF075-2, PTS181213V075, and 1812L075PR are rated MSL 1 (unlimited), indicating superior moisture resistance.
