PFVS.210 Polymeric PTC Resettable Fuse Equivalent & Substitute Parts

Part Overview

The PFVS.210 is a polymeric PTC resettable fuse manufactured by SCHURTER Inc., rated for 16V at 2.1A hold current with a 4.7A trip current. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and procurement. The PFVS.210 series provides overcurrent protection in applications requiring automatic reset functionality without component replacement. Due to its obsolete status, sourcing alternatives from active product lines is necessary for new designs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PFVS.210 is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, VTP210GF from Littelfuse Inc., qualifies based on the following criteria:

Electrical parameters match exactly: 16V maximum voltage, 2.1A hold current, 4.7A trip current, 5-second trip time, 18 mOhms minimum initial resistance, and 60 mOhms maximum post-trip resistance. Both components operate across the identical temperature range of -40°C to 85°C and maintain the same 100A maximum current rating.

Mechanical compatibility is confirmed through identical package type (Strap) and thickness (0.032" / 0.80mm). Dimensional variations in length and width (PFVS.210: 22.30mm x 5.10mm; VTP210GF: 23.10mm x 5.30mm) remain within acceptable tolerances for strap-mounted applications.

Regulatory compliance is maintained: both components carry CSA, TUV, and UL approvals and are ROHS3 compliant. The VTP210GF holds active product status with established supply availability, whereas the PFVS.210 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The VTP210GF from Littelfuse Inc. is the direct equivalent for PFVS.210 applications. Selection is supported by three primary factors:

Electrical equivalence is complete across all specified parameters, ensuring identical circuit protection behavior and response characteristics in the target application.

Regulatory compliance is maintained through identical certification marks (CSA, TUV, UL) and ROHS3 compliance status, satisfying procurement and environmental requirements.

Product availability is secured through active manufacturing status of the VTP210GF, eliminating supply chain risk associated with the obsolete PFVS.210. Current inventory of 2280 units supports immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can VTP210GF replace PFVS.210 in existing designs? A: Yes. Electrical parameters, operating temperature range, and regulatory certifications are identical. The strap package and mounting type are equivalent. Dimensional tolerances in length and width are acceptable for strap-mounted applications.

Q: What are the key parameters that determine substitution eligibility? A: Voltage rating (16V), hold current (2.1A), trip current (4.7A), trip time (5s), initial resistance (18 mOhms minimum), post-trip resistance (60 mOhms maximum), operating temperature range (-40°C to 85°C), and package type (Strap) must match exactly.

Q: Why is PFVS.210 listed as obsolete? A: PFVS.210 is no longer in active production. VTP210GF from Littelfuse represents the current active equivalent for this protection rating and package configuration.

Q: Are there compliance differences between PFVS.210 and VTP210GF? A: No. Both components carry identical approvals (CSA, TUV, UL) and are ROHS3 compliant. REACH status is unaffected for both parts.

Q: What is the difference in physical dimensions? A: PFVS.210 measures 22.30mm L x 5.10mm W; VTP210GF measures 23.10mm L x 5.30mm W. Both share identical thickness (0.80mm). These minor variations are within acceptable tolerances for strap-mounted applications.

Q: Is inventory availability a consideration? A: VTP210GF has 2280 units in stock versus 1008 units for the obsolete PFVS.210. The active product status of VTP210GF ensures long-term supply continuity.
