Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0ZCC0110FF2C is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Voltage rating: 8V maximum
• Current hold (Ih): 1.1A nominal
• Current trip (It): 2.2A nominal
• Resistance initial (Ri): 40 mOhms minimum
• Resistance post-trip (R1): 210 mOhms maximum
• Package: 1812 (4532 Metric) surface mount
• Operating temperature range: -40°C to 85°C
• Time to trip: 300 ms

Substitution Categories:

Direct Equivalent (Identical Electrical & Mechanical Specifications):

• 0ZCG0110FF2C (Bel Fuse Inc.) — Same series evolution, active status, AEC-Q200 rated
• 1812L110PR (Littelfuse Inc.) — Identical electrical parameters, POLY-FUSE® series
• MINISMDC110F-2 (Littelfuse Inc.) — PolySwitch® miniSMD series, identical specifications
• PTS18128V110 (Eaton - Electronics Division) — PTS1812 series, identical electrical parameters

Partial Equivalent (Voltage or Current Variation):

• MF-MSMF110-2 (Bourns Inc.) — 6V maximum voltage (lower than 8V specification); otherwise identical electrical parameters
• 1812L150ZR (Littelfuse Inc.) — 1.25A hold current and 3A trip current (higher than 1.1A/2.2A specification); 8V voltage maintained

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical & Mechanical Performance):

Select from 0ZCG0110FF2C, 1812L110PR, MINISMDC110F-2, or PTS18128V110. All four parts maintain the 8V/1.1A electrical specification and 1812 package footprint. The 0ZCG0110FF2C offers active product status with AEC-Q200 automotive qualification. The 1812L110PR, MINISMDC110F-2, and PTS18128V110 are all active products with established supply chains and ROHS3 compliance.

For Applications with 6V System Voltage:

The MF-MSMF110-2 (Bourns Multifuse® series) is suitable only for circuits operating at 6V maximum. This part is not interchangeable with the 0ZCC0110FF2C in 8V applications.

For Applications Requiring Higher Current Margin:

The 1812L150ZR (Littelfuse POLY-FUSE® series) provides 1.25A hold current and 3A trip current, offering increased current capacity. This part is suitable only for applications where the higher trip threshold does not compromise circuit protection strategy.

Compliance Considerations:

All active substitute parts carry ROHS3 compliance. The 0ZCG0110FF2C includes AEC-Q200 automotive qualification. The MINISMDC110F-2 carries CSA, TUV, and UL approvals. Selection should align with end-application regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can 0ZCG0110FF2C directly replace 0ZCC0110FF2C?

A: Yes. Both parts share identical electrical parameters (8V, 1.1A hold, 2.2A trip, 40 mOhms initial resistance, 210 mOhms post-trip resistance) and 1812 package dimensions. The 0ZCG0110FF2C is the active product evolution of the obsolete 0ZCC series and includes AEC-Q200 qualification.

Q: What is the difference between "Direct Equivalent" and "Partial Equivalent" substitutes?

A: Direct equivalents maintain all critical electrical parameters: 8V voltage, 1.1A hold current, 2.2A trip current, and 210 mOhms post-trip resistance. Partial equivalents vary in voltage rating (MF-MSMF110-2 at 6V) or current rating (1812L150ZR at 1.25A/3A), requiring circuit-level evaluation before substitution.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the 1812 (4532 Metric) surface mount package. However, thickness varies: the main part is 0.022" (0.55mm), while substitutes range from 0.022" to 0.049" (0.55mm to 1.25mm). PCB assembly equipment and board layout must accommodate the thicker variants, particularly the 1812L150ZR at 0.049" thickness.

Q: Which substitute part has the best supply availability?

A: MINISMDC110F-2 (Littelfuse PolySwitch® miniSMD series) shows the highest inventory level at 103,300 pieces. This part maintains identical electrical specifications and includes CSA, TUV, and UL approvals.

Q: Can MF-MSMF110-2 be used in an 8V circuit?

A: No. The MF-MSMF110-2 is rated for 6V maximum voltage. Using this part in an 8V circuit exceeds its voltage rating and compromises device reliability and protection function.

Q: What is the impact of different post-trip resistance values?

A: The 0ZCC0110FF2C and most direct equivalents specify 210 mOhms maximum post-trip resistance. The 1812L150ZR specifies 110 mOhms maximum, resulting in lower circuit resistance after fuse activation. This affects power dissipation and circuit behavior during the recovery phase and should be evaluated for specific applications.

Q: Are there moisture sensitivity differences between substitutes?

A: Yes. The main part and MINISMDC110F-2 specify MSL 2A (4 weeks). The 1812L110PR, PTS18128V110, MF-MSMF110-2, and 1812L150ZR specify MSL 1 (unlimited), indicating superior moisture resistance and longer shelf life without desiccant storage requirements.
