PC06F1.5A Surface Mount Fuse - Equivalent & Substitute Parts

Part Overview

The PC06F1.5A is a 1.5 A, 32 V AC/DC surface mount board fuse manufactured by Eaton - Electronics Division, packaged in 0603 (1608 Metric) form factor. This component is classified as Obsolete product status. Due to its obsolescence, equivalent substitute parts with active production status are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PC06F1.5A is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 1.5 A (exact match required)
• Voltage Rating - AC: 32 V (exact match required)
• Voltage Rating - DC: 32 V minimum (equal or higher acceptable)
• Response Time: Fast Blow (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)

Acceptable Variation Parameters:

• Breaking Capacity @ Rated Voltage: 35 A or higher acceptable
• DC Cold Resistance: variation acceptable within functional limits
• Melting I²t: variation acceptable within functional limits
• Operating Temperature Range: wider range acceptable
• Approval Agencies: CSA and/or UL acceptable
• RoHS Compliance: compliant status acceptable

The substitute parts listed below meet all critical matching parameters and are therefore electrically and mechanically interchangeable with the PC06F1.5A in board-level applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TR/0603FA1.5-R (Eaton - Electronics Division)

The TR/0603FA1.5-R is the recommended primary substitute for the obsolete PC06F1.5A. Both components are manufactured by Eaton and share identical electrical specifications (1.5 A, 32 V AC/DC, Fast Blow, 0603 package). The TR/0603FA1.5-R maintains active product status with improved compliance certifications (CSA and UL approval), RoHS compliance, and superior moisture sensitivity rating (MSL 1 vs. MSL 2). The TR/0603FA1.5-R is available in Tape & Reel packaging with significantly higher inventory availability (20,300 pcs vs. 984 pcs for the main part).

Secondary Substitute: 043801.5WR (Littelfuse Inc.)

The 043801.5WR is an alternative substitute manufactured by Littelfuse Inc. This component matches all critical electrical parameters (1.5 A, 32 V AC, Fast Blow, 0603 package) and offers enhanced DC voltage rating (63 V vs. 32 V), providing additional design margin in applications with DC voltage transients. The 043801.5WR carries active product status, dual certification (CSA and UL), ROHS3 compliance, and extended operating temperature range (-55°C ~ 150°C). Breaking capacity matches the main part at 50 A. This substitute is suitable for applications requiring higher DC voltage tolerance or extended temperature operation.

Selection Criteria:

• For direct replacement with minimal design change: Select TR/0603FA1.5-R
• For enhanced DC voltage margin or extended temperature range: Select 043801.5WR
• For cost optimization: Verify current inventory and pricing; both substitutes are in active production

All substitute parts are electrically and mechanically compatible with the PC06F1.5A in standard board-level fuse applications.

Frequently Asked Questions (FAQ)

Q1: Can TR/0603FA1.5-R directly replace PC06F1.5A without PCB modification?

A: Yes. The TR/0603FA1.5-R is mechanically and electrically identical to the PC06F1.5A. Both use 0603 (1608 Metric) surface mount package with identical footprint dimensions. No PCB layout changes are required.

Q2: What is the difference between the two substitute parts?

A: Both TR/0603FA1.5-R and 043801.5WR meet the core electrical requirements (1.5 A, 32 V AC/DC, Fast Blow). The primary differences are: (1) TR/0603FA1.5-R is manufactured by Eaton (same as main part); (2) 043801.5WR offers higher DC voltage rating (63 V vs. 32 V) and extended operating temperature (-55°C ~ 150°C vs. -55°C ~ 125°C); (3) DC cold resistance and melting I²t values differ, affecting thermal response characteristics.

Q3: Is the higher DC voltage rating of 043801.5WR (63 V) a concern for 32 V DC applications?

A: No. Higher voltage rating does not create compatibility issues in lower voltage applications. The 043801.5WR will function correctly in 32 V DC circuits and provides additional safety margin against voltage transients.

Q4: What does "Fast Blow" response time mean?

A: Fast Blow indicates the fuse operates with rapid response to overcurrent conditions, typically within milliseconds. All three parts (main and substitutes) share this characteristic, ensuring consistent circuit protection behavior.

Q5: Are there packaging differences between the substitutes?

A: Yes. The PC06F1.5A is supplied in standard packaging (not specified). The TR/0603FA1.5-R is supplied in Tape & Reel (TR) format. The 043801.5WR is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging formats are standard for automated assembly processes.

Q6: Do the substitutes meet the same approval standards?

A: The PC06F1.5A carries UL approval. Both substitutes carry dual certification (CSA and UL), which exceeds the original part's approval status. This provides broader geographic and application acceptance.

Q7: What is the significance of RoHS compliance in the substitutes?

A: RoHS compliance indicates the parts are manufactured without restricted hazardous substances (lead, cadmium, mercury, etc.). The TR/0603FA1.5-R is RoHS Compliant; the 043801.5WR is ROHS3 Compliant. Both meet modern environmental and regulatory requirements for electronics manufacturing.

Q8: Why does the main part have MSL 2 while substitutes have MSL 1?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture absorption during storage. MSL 1 (unlimited shelf life) is superior to MSL 2 (1 year shelf life). The substitutes offer better long-term storage stability without requiring special moisture-controlled packaging.
