HVR600P150CF Equivalent & Substitute Parts

Part Overview

The HVR600P150CF is a polymeric PTC resettable fuse manufactured by Littelfuse Inc., rated for 60V maximum voltage with 150 mA hold current. This component is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement. The part operates across a temperature range of -40°C to 85°C and is approved by cURus and TUV agencies. Substitute parts maintain the same electrical ratings and mechanical form factor while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: maximum voltage rating, hold current (Ih), trip current (It), mounting type, package configuration, and lead spacing. All substitute parts listed maintain identical or superior electrical characteristics within the specified operating temperature range.

The HVR600P150CF has three qualified substitutes:

600R150ZR and 600R150-RAF: Direct electrical equivalents with 60V maximum voltage and 150 mA hold current. Both are active products in the POLY-FUSE® 600R series with identical lead spacing (0.201"). These parts differ only in packaging format (Cut Tape vs. Bulk) and minor resistance variations within acceptable tolerances.

TRF600-150: Functionally compatible substitute with higher voltage rating (250V maximum) and expanded current capacity (40 A maximum vs. 3 A). This PolySwitch® series component maintains the same hold current (150 mA) and trip current (300 mA) specifications. Lead spacing is 0.197" (5.00mm), representing a 0.01mm variance from the original specification.

Engineering Selection Recommendations

600R150ZR is the primary substitute for direct replacement in applications requiring 60V operation. This part maintains identical electrical specifications and lead spacing while offering active product status and superior availability (2208 units in stock). Cut Tape packaging supports automated assembly processes.

600R150-RAF provides an alternative for bulk procurement scenarios. As a manufacturer-recommended equivalent, it delivers the same 60V rating and 150 mA hold current with active product status. Bulk packaging is suitable for high-volume manufacturing environments.

TRF600-150 is applicable only in circuit designs where the higher 250V voltage rating does not create overvoltage conditions. This PolySwitch® series component offers expanded current capacity (40 A maximum) and broader agency approvals (CSA, TUV, UL). The 0.01mm lead spacing variance is within standard PCB tolerance specifications. This substitute is suitable for applications requiring higher voltage headroom or increased current handling capability.

All three substitutes maintain ROHS3 compliance and operate across the identical -40°C to 85°C temperature range as the original part.

Frequently Asked Questions (FAQ)

Q: Can 600R150ZR directly replace HVR600P150CF on existing PCBs?

A: Yes. The 600R150ZR maintains identical electrical ratings (60V, 150 mA hold current), lead spacing (0.201"), and radial disc package configuration. No circuit modifications are required.

Q: What is the difference between 600R150ZR and 600R150-RAF?

A: Both parts are electrically equivalent with identical voltage and current ratings. The primary difference is packaging: 600R150ZR is supplied in Cut Tape format for automated assembly, while 600R150-RAF is supplied in Bulk format for manual assembly or high-volume reel processing. Resistance specifications vary slightly (600R150ZR: 17 Ohms max post-trip vs. 600R150-RAF: 20 Ohms max post-trip), both within acceptable operating tolerances.

Q: When should TRF600-150 be used instead of the 600R series substitutes?

A: TRF600-150 is selected for applications operating at voltages above 60V, up to 250V. The higher voltage rating provides additional safety margin in circuits with voltage transients or higher nominal operating voltages. The 0.01mm lead spacing difference (0.197" vs. 0.201") is compatible with standard PCB hole spacing tolerances.

Q: Are all substitutes RoHS compliant?

A: Yes. HVR600P150CF, 600R150ZR, 600R150-RAF, and TRF600-150 are all ROHS3 compliant.

Q: What certifications apply to each substitute?

A: 600R150ZR and 600R150-RAF carry cURus and TUV approvals, matching the original part. TRF600-150 carries CSA, TUV, and UL approvals, providing broader regulatory coverage.

Q: Does the 4-second trip time of substitutes affect circuit performance compared to the 5-second trip time of HVR600P150CF?

A: The 1-second difference in trip time is within normal PTC fuse response variation. Both trip times meet standard overcurrent protection requirements. Circuit performance is not adversely affected by this specification variance.
