ATC-5 Equivalent & Substitute Parts

Part Overview

The ATC-5 is a 5 A automotive blade fuse rated for 32 V DC operation, manufactured by Eaton - Bussmann Electrical Division. This fast-blow fuse is designed for automotive electrical circuits requiring holder-based mounting in the ATO/ATC blade format. The part maintains active product status with UL approval and RoHS compliance. Substitute parts are identified when identical electrical and mechanical parameters are maintained across the same fuse category and package specification.

Substitute Part Grouping Explanation

Substitute parts for the ATC-5 are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Current Rating: 5 A (exact match required)
• Voltage Rating (DC): 32 V (exact match required)
• Fuse Type: Automotive (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: Blade, ATO/ATC (exact match required)
• Breaking Capacity @ Rated Voltage: 1 kA (exact match required)
• Series: ATC® (exact match required)
• Physical Dimensions: 0.760" L x 0.207" W x 0.492" H (exact match required)

The BK/ATC-5 meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both ATC-5 and BK/ATC-5 are active products from the same manufacturer with identical electrical and mechanical specifications. The BK/ATC-5 carries ROHS3 compliance status compared to the standard RoHS Compliant designation of the ATC-5. Both parts maintain UL approval and are suitable for direct substitution in automotive blade fuse applications requiring 5 A at 32 V DC with fast-blow response characteristics. Selection between these parts may be based on inventory availability or specific compliance requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can BK/ATC-5 be used as a direct replacement for ATC-5?

A: Yes. Both parts are parametric equivalents with identical current rating (5 A), voltage rating (32 V DC), fuse type (automotive), response time (fast blow), package format (blade ATO/ATC), breaking capacity (1 kA), and physical dimensions. Both are manufactured by Eaton - Bussmann Electrical Division and carry UL approval.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS directives. ROHS3 represents compliance with the most recent RoHS 3 directive. Both parts meet environmental compliance requirements for the specified application.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.760" L x 0.207" W x 0.492" H (19.30 mm x 5.25 mm x 12.50 mm) and use the same blade ATO/ATC package format, ensuring mechanical compatibility with standard automotive fuse holders.

Q: Do both parts require a fuse holder?

A: Yes. Both ATC-5 and BK/ATC-5 are blade-type fuses that require a compatible ATO/ATC fuse holder for installation in automotive electrical circuits.

Q: What is the breaking capacity specification?

A: Both parts have a breaking capacity of 1 kA at rated voltage (32 V DC), indicating the maximum fault current the fuse can safely interrupt.
