PCF-1-1/2-R Equivalent & Substitute Parts

Part Overview

The PCF-1-1/2-R is a 1.5 A board mount fuse manufactured by Eaton - Electronics Division, rated for 250 V AC and 450 V DC operation. This through-hole radial fuse is part of the PC-Tron® series and is designed for fast-blow response applications requiring circuit protection in industrial and commercial electronics. The component maintains Active product status with full CSA and UL approval agency certifications. Substitute parts are identified to address inventory availability, alternative sourcing requirements, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on parametric equivalence:

Parametric Equivalent Parts maintain identical electrical specifications across all critical parameters: 1.5 A current rating, 250 V AC / 450 V DC voltage ratings, fast-blow response, 50A AC / 5.9kA DC breaking capacity, 0.09 melting I²t, and identical physical dimensions (0.350" L x 0.184" W x 0.345" H). These parts are direct functional replacements with no derating or circuit redesign required. All parametric equivalents are manufactured by Eaton - Electronics Division within the PC-Tron® series and carry identical CSA and UL certifications.

Similar Parts share the same current rating (1.5 A) and mounting configuration (through-hole board mount, radial box package) but differ in voltage ratings, breaking capacity, melting I²t, physical dimensions, and manufacturer. The part 0698Q1500-02 from Bel Fuse Inc. operates at 350 V AC / 140 V DC with higher breaking capacity (100A AC, 150A DC) and different thermal characteristics (0.64 melting I²t). This part is suitable only for applications where the higher AC voltage rating and lower DC voltage rating align with circuit requirements, and where the different thermal response is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Parametric Equivalents): Parts BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R are direct electrical and mechanical equivalents to PCF-1-1/2-R. All three parts maintain identical current ratings, voltage ratings (250 V AC / 450 V DC), breaking capacity, melting I²t, physical dimensions, and approval certifications (CSA, UL). These parts are interchangeable without circuit modification and are suitable for inventory substitution or alternative sourcing within the Eaton PC-Tron® product line. Selection among these three equivalents may be based on packaging format (Bulk) and inventory availability.

Conditional Substitution (Similar Parts): The part 0698Q1500-02 from Bel Fuse Inc. is suitable only for applications where the circuit voltage specifications align with its 350 V AC / 140 V DC ratings. This part is not suitable for circuits requiring 450 V DC operation. The higher breaking capacity (100A AC, 150A DC) and different melting I²t (0.64 versus 0.09) indicate different thermal response characteristics. This part carries AEC-Q200 automotive qualification and CE marking, making it suitable for automotive and European market applications where these certifications are required. Physical dimensions differ slightly, requiring PCB layout verification before implementation.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R be used interchangeably with PCF-1-1/2-R?

A: Yes. These three parts are parametric equivalents with identical electrical specifications (1.5 A, 250 V AC, 450 V DC), identical breaking capacity (50A AC, 5.9kA DC), identical melting I²t (0.09), identical physical dimensions, and identical certifications (CSA, UL). They are direct functional replacements requiring no circuit redesign.

Q: Is 0698Q1500-02 a direct replacement for PCF-1-1/2-R?

A: No. While 0698Q1500-02 shares the same 1.5 A current rating and fast-blow response, it differs in critical voltage ratings (350 V AC / 140 V DC versus 250 V AC / 450 V DC), breaking capacity, melting I²t, and physical dimensions. This part is suitable only for circuits designed for 350 V AC / 140 V DC operation. The 140 V DC rating makes it unsuitable for applications requiring 450 V DC protection.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: current rating (1.5 A), voltage ratings (AC and DC), response time (fast blow), mounting type (through hole), fuse type (board mount), package configuration (radial box), breaking capacity, and melting I²t. Physical dimensions must also match to ensure PCB footprint compatibility. Approval certifications (CSA, UL) must be maintained for regulated applications.

Q: Can I use 0698Q1500-02 in a 450 V DC circuit?

A: No. The 0698Q1500-02 is rated for 140 V DC maximum. Using this part in a 450 V DC circuit exceeds its voltage rating and creates a safety hazard. The part would not provide adequate protection and could fail catastrophically.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed (PCF-1-1/2-R, BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, PCB-1-1/2-R, and 0698Q1500-02) are ROHS3 compliant, meeting environmental and hazardous substance restrictions.

Q: What is the difference in packaging between the Eaton parts and 0698Q1500-02?

A: The three Eaton parametric equivalents (BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, PCB-1-1/2-R) are supplied in Bulk packaging. The 0698Q1500-02 is supplied in Cut Tape (CT) packaging. Packaging format affects handling, storage, and automated assembly compatibility but does not affect electrical performance.

Q: Do the physical dimension differences between PCF-1-1/2-R and 0698Q1500-02 affect PCB compatibility?

A: Yes. The 0698Q1500-02 has different dimensions (0.329" L x 0.157" W x 0.303" H versus 0.350" L x 0.184" W x 0.345" H). PCB footprint, hole spacing, and component clearance must be verified before substitution. The smaller dimensions may require PCB layout modification.
