Equivalent & Substitute Parts for 0ZCD0150FF2C

Part Overview

The 0ZCD0150FF2C is a polymeric PTC resettable fuse manufactured by Bel Fuse Inc., rated for 33V maximum voltage and 1.5A hold current in a 2920 surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part provides overcurrent protection with automatic reset capability across industrial and consumer applications operating between -40°C and 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0ZCD0150FF2C is determined by the following critical parameters:

Primary Compatibility Criteria:

• Current - Hold (Ih): 1.5 A (exact match required)
• Current - Trip (It): 3 A (exact match required)
• Type: Polymeric PTC Resettable Fuse (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)

Secondary Compatibility Criteria:

• Voltage - Max: 33V or higher (equal or greater voltage rating acceptable)
• Resistance - Initial (Ri): 50 mOhms or lower (equal or lower acceptable)
• Resistance - Post Trip (R1): 230 mOhms or lower (equal or lower acceptable)

The substitute parts listed below meet these criteria with the following considerations:

0ZCF0150FF2C (Bel Fuse Inc.): Direct manufacturer upgrade with identical electrical specifications and active product status. Concave package variant of the same series.

MF-SM150-2 (Bourns Inc.) and SMD150F-2 (Littelfuse Inc.): Functionally equivalent alternatives with matching hold and trip currents. These parts operate at 15V maximum voltage, which is lower than the original 33V rating, and use different package geometries (2-SMD vs. 2920). These substitutes are suitable only for applications where the circuit voltage does not exceed 15V.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 0ZCF0150FF2C

The 0ZCF0150FF2C is the preferred direct substitute for the obsolete 0ZCD0150FF2C. Both parts are manufactured by Bel Fuse Inc. and share identical electrical specifications: 33V maximum voltage, 1.5A hold current, 3A trip current, and 2920 package form factor. The 0ZCF0150FF2C holds active product status with expanded certifications including AEC-Q200 compliance and ROHS3 certification, ensuring long-term availability and regulatory compliance for new designs.

Alternative Recommendations: MF-SM150-2 and SMD150F-2

The MF-SM150-2 (Bourns Inc.) and SMD150F-2 (Littelfuse Inc.) are functionally equivalent alternatives for applications where circuit voltage does not exceed 15V. Both parts maintain the 1.5A hold current and 3A trip current specifications. Selection between these alternatives depends on package availability and PCB layout constraints, as both use 2-SMD packages rather than the original 2920 form factor. The MF-SM150-2 offers superior current handling (100A maximum) and lower moisture sensitivity (MSL 1), while the SMD150F-2 provides broader approval agency certifications (CSA, TUV, UL).

Frequently Asked Questions (FAQ)

Q: Can the 0ZCF0150FF2C directly replace the 0ZCD0150FF2C without PCB modifications?

A: Yes. Both parts use the 2920 (7351 Metric) surface mount package with identical footprints. The 0ZCF0150FF2C features a concave package variant, which is mechanically compatible with standard 2920 pads. No PCB layout changes are required.

Q: What is the voltage limitation when using MF-SM150-2 or SMD150F-2 as substitutes?

A: Both alternatives are rated for 15V maximum voltage, compared to the original 33V rating. These parts are suitable only for circuits operating at 15V or below. Using these substitutes in circuits exceeding 15V will result in device failure and loss of overcurrent protection.

Q: Are there differences in trip response time between the substitute parts?

A: Yes. The 0ZCD0150FF2C and 0ZCF0150FF2C both trip within 2 seconds, while MF-SM150-2 and SMD150F-2 require 5 seconds to trip. Applications with strict timing requirements for overcurrent response must account for this difference.

Q: Which substitute offers the best long-term availability?

A: The 0ZCF0150FF2C is the recommended choice for long-term production. It holds active product status with the highest inventory levels (177,523 pieces) and includes AEC-Q200 automotive qualification, ensuring sustained supply and regulatory compliance across multiple market segments.

Q: Do the substitute parts require different moisture handling procedures?

A: The 0ZCF0150FF2C maintains the same MSL 2A (4 Weeks) rating as the original part. The MF-SM150-2 offers improved moisture tolerance with MSL 1 (Unlimited), while SMD150F-2 matches the original MSL 2A specification. Storage and handling procedures should follow the specific MSL rating of the selected substitute.
