Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: maximum voltage rating, hold current (Ih), trip current (It), initial resistance (Ri), post-trip resistance (R1), operating temperature range, package type, and surface mount configuration. Parts are categorized as follows:

Direct Equivalents: Parts matching all electrical parameters and voltage rating (8V, 2A Ih, 4.6A It, 20 mOhms Ri, 70 mOhms R1 max).

Parametric Equivalents: Parts with identical electrical performance but different voltage ratings (12V, 16V) or minor resistance variations within acceptable tolerance.

Similar Parts: Parts meeting core electrical specifications with minor deviations in post-trip resistance or trip current characteristics.

Engineering Selection Recommendations

Primary Direct Equivalent: 0ZCG0200FF2C (Bel Fuse Inc.) provides identical electrical specifications with active product status and ROHS3 compliance. This part maintains the same series lineage and is the preferred replacement for direct substitution.

Alternative Direct Equivalents: 1812L200THPR (Littelfuse Inc.) and FSMD200R (RFE/Fuzetec) both match all critical electrical parameters with active status and full compliance certifications. These parts are suitable for direct replacement in applications requiring 8V, 2A hold current protection.

Voltage-Rated Alternatives: 1812L200/12DR (12V) and 1812L200/16DR (16V) provide higher voltage ratings while maintaining identical current and resistance specifications. These parts are applicable in circuits where the system voltage exceeds 8V but does not exceed the rated maximum.

Parameter-Variant Option: MF-MSMF200-2 (Bourns Inc.) exhibits minor deviations in trip current (4A vs. 4.6A) and post-trip resistance (80 mOhms vs. 70 mOhms max), with extended trip time (3s vs. 2s). This part is suitable only where these parameter variations are acceptable to the application design.

Compliance Consideration: All active substitute parts carry ROHS3 compliance certification, ensuring regulatory alignment for modern manufacturing environments. The original 0ZCC0200FF2C does not specify RoHS status; verification against specific regulatory requirements is necessary.

Frequently Asked Questions (FAQ)

Q: Can 0ZCG0200FF2C directly replace 0ZCC0200FF2C?

A: Yes. Both parts share identical electrical specifications (8V, 2A Ih, 4.6A It, 20 mOhms Ri, 70 mOhms R1 max) and the same 1812 surface mount package. The primary difference is product status: 0ZCG0200FF2C is active with ROHS3 compliance, while 0ZCC0200FF2C is obsolete.

Q: What is the difference between 1812L200THPR and 1812L200/12DR?

A: The primary difference is voltage rating. 1812L200THPR is rated for 8V maximum, while 1812L200/12DR is rated for 12V maximum. Both maintain identical current hold (2A), trip current (4.6A), and resistance specifications. Select based on your circuit's maximum operating voltage.

Q: Can I use MF-MSMF200-2 as a direct replacement?

A: MF-MSMF200-2 is functionally compatible but exhibits parameter variations: trip current is 4A (vs. 4.6A), post-trip resistance is 80 mOhms max (vs. 70 mOhms), and trip time is 3 seconds (vs. 2 seconds). Use only if your application design accommodates these deviations.

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

A: All listed parts use 1812 (4532 metric) surface mount packages with concave geometry. Packaging formats vary (Tape & Reel, Cut Tape & Digi-Reel); verify packaging availability with your supplier for production requirements.

Q: Which substitute offers the best compliance for modern designs?

A: All active substitute parts (0ZCG0200FF2C, 1812L200THPR, MF-MSMF200-2, 1812L200/16DR, PTS18128V200, 1812L200/12DR, FSMD200R) carry ROHS3 compliance. Selection should be based on voltage rating, electrical parameter match, and supply chain availability.

Q: What is the significance of the 2-second trip time specification?

A: Trip time indicates the response speed to overcurrent conditions. The 0ZCC0200FF2C and most direct equivalents respond within 2 seconds at trip current (4.6A). MF-MSMF200-2 has a 3-second trip time; verify this meets your circuit protection timing requirements before substitution.
