Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0ZCC0260AF2B is determined by strict equivalence across the following critical parameters:

• Voltage rating (13.2V nominal)
• Current hold rating (2.6A)
• Current trip rating (5A)
• Package form factor (1812 / 4532 Metric, Concave)
• Mounting type (Surface Mount)
• Resistance characteristics (Ri min 15 mOhms, R1 max 50 mOhms)
• Operating temperature range (-40°C ~ 85°C)

Substitute parts are categorized as follows:

Direct Equivalents (13.2V, 2.6A): Parts with identical voltage and current ratings, differing only in series designation or packaging format.

Parametric Equivalents (16V, 2.6A): Parts with higher voltage rating but identical current characteristics. These are suitable for applications where the 13.2V rating is not a limiting constraint.

Similar Parts (12V, 2.6A): Parts with lower voltage rating but matching current and thermal characteristics. Compatibility depends on circuit voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Direct Equivalent: The 0ZCG0260AF2B (Bel Fuse Inc.) is the direct successor to the obsolete 0ZCC0260AF2B. It maintains identical electrical specifications and package form factor while offering active product status and AEC-Q200 compliance. This part is the preferred choice for direct replacement in existing designs.

Alternative Direct Equivalent: The MINISMDC260F/13.2-2 (Littelfuse Inc., PolySwitch® miniSMD series) provides equivalent electrical performance with identical voltage and current ratings. This part carries CSA, TUV, and UL approvals and is available in active status.

Parametric Equivalent (Higher Voltage Rating): The 0ZCG0260BF2B and MINISMDC260F/16-2 offer 16V ratings with identical 2.6A hold current specifications. These parts are suitable for applications where circuit voltage does not exceed 16V and where higher voltage margin is acceptable. The FSMD260-16R (RFE/Fuzetec) provides an additional 16V option with equivalent electrical characteristics.

Similar Part (Lower Voltage Rating): The 1812L260/12MR (Littelfuse Inc., POLY-FUSE® 1812L series) operates at 12V with matching 2.6A current ratings. This part is suitable only for applications where the circuit voltage does not exceed 12V. Note the post-trip resistance maximum is 55 mOhms versus 50 mOhms for the primary part.

Compliance Considerations: All recommended substitutes carry appropriate regulatory approvals (cURus, TUV, UL, CSA). The 0ZCG0260AF2B and 0ZCG0260BF2B include AEC-Q200 certification, making them suitable for automotive applications. All active parts are ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can I use the 0ZCG0260BF2B (16V) in place of the 0ZCC0260AF2B (13.2V)? A: Yes. The 16V part is electrically compatible with circuits designed for 13.2V operation. The higher voltage rating provides additional safety margin and does not affect circuit performance when the actual operating voltage remains at or below 13.2V.

Q: What is the difference between the Bel Fuse and Littelfuse substitutes? A: Both manufacturers provide equivalent electrical performance across all critical parameters. The primary differences are series designation (0ZCG vs. miniSMD), packaging format options, and regulatory certifications. Selection may depend on procurement availability and specific packaging requirements.

Q: Is the 1812L260/12MR suitable for my application? A: The 12V part is suitable only if your circuit voltage does not exceed 12V. If your design operates at 13.2V or higher, this part will not provide adequate voltage protection and should not be used.

Q: What does "Concave" mean in the package description? A: Concave refers to the physical shape of the component's top surface. All substitute parts listed maintain this same package geometry, ensuring mechanical compatibility with existing PCB layouts and solder reflow profiles.

Q: Are there differences in moisture sensitivity between these parts? A: Most parts carry MSL 2A (4 Weeks) rating. The FSMD260-13R and FSMD260-16R carry MSL 2 (1 Year), providing extended shelf life. The 1812L260/12MR carries MSL 1 (Unlimited), offering the most favorable moisture handling characteristics.

Q: Can I mix different manufacturers in the same production run? A: Yes, provided all parts meet the specified electrical parameters and regulatory requirements. Ensure procurement and quality assurance processes account for manufacturer-specific documentation and certifications.
