Substitute Part Grouping Explanation

Substitution eligibility for the 0ZSC0600FF1E is determined by strict equivalence across the following critical parameters:

• Voltage rating: 20V maximum
• Hold current (Ih): 6A maximum
• Trip current (It): 11.7A
• Time to trip: 5 seconds
• Initial resistance (Ri): 7 mOhms minimum
• Post-trip resistance (R1): 19 mOhms maximum
• Operating temperature range: -40°C to 85°C
• Package type: Strap configuration
• Physical dimensions: 25.00mm L x 14.20mm W x 1.00mm thickness maximum
• RoHS3 compliance and MSL Level 1 rating

The LR4-600F from Littelfuse Inc. meets all specified electrical and mechanical parameters, making it a direct functional equivalent for applications requiring polymeric PTC resettable fuse protection at these ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ZSC0600FF1E and LR4-600F are active production components with full RoHS3 compliance and unlimited moisture sensitivity rating. The LR4-600F carries additional approval certifications (CSA, TUV, UL) compared to the 0ZSC0600FF1E (cURus, TUV). Selection between these parts should be based on supply availability, lead time requirements, and specific certification requirements for the end application. The LR4-600F currently has higher inventory availability (12,319 units) compared to the 0ZSC0600FF1E (864 units).

Frequently Asked Questions (FAQ)

Q: Can the LR4-600F replace the 0ZSC0600FF1E in existing designs?

A: Yes. Both components share identical electrical specifications (20V, 6A hold current, 11.7A trip current, 5-second trip time), identical resistance characteristics, and identical physical dimensions in strap package configuration. No circuit modifications are required.

Q: Are there differences in approval certifications between these parts?

A: The 0ZSC0600FF1E carries cURus and TUV approvals. The LR4-600F carries CSA, TUV, and UL approvals. Applications requiring specific certification marks should verify alignment with end-product requirements.

Q: What is the significance of the strap package type?

A: The strap package indicates a user-defined mounting configuration with solder leads. Both parts maintain identical dimensions (25.00mm x 14.20mm x 1.00mm maximum thickness), ensuring mechanical compatibility in PCB layouts and assembly processes.

Q: Do these parts have identical thermal operating ranges?

A: Yes. Both the 0ZSC0600FF1E and LR4-600F operate across the same temperature range of -40°C to 85°C with identical time-to-trip characteristics across this range.

Q: What is the difference between hold current and trip current?

A: Hold current (Ih) of 6A is the maximum continuous current the fuse allows without activation. Trip current (It) of 11.7A is the threshold at which the fuse activates protection. Both specifications are identical across these parts.
