ATC-35 Equivalent & Substitute Parts

Part Overview

The ATC-35 is a 35 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 systems requiring holder-based installation with ATO/ATC blade configuration. 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 manufacturers or product lines, ensuring direct interchangeability in automotive fuse applications.

Substitute Part Grouping Explanation

Substitution for the ATC-35 is determined by strict equivalence across the following critical parameters:

• Current Rating: 35 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)
• Mounting Type: Requires Holder (exact match required)
• Physical Dimensions: 0.760" L x 0.207" W x 0.492" H (exact match required)

The substitute part BK/ATC-35 meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both ATC-35 and BK/ATC-35 are active products manufactured by Eaton - Bussmann Electrical Division with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, RoHS compliance level requirements, or REACH status considerations. The BK/ATC-35 carries ROHS3 compliance designation and REACH Unaffected status, providing additional regulatory documentation for applications requiring enhanced compliance tracking. Both parts maintain UL approval and identical breaking capacity ratings, ensuring equivalent performance in automotive fuse applications.

Frequently Asked Questions (FAQ)

Q: Can BK/ATC-35 be used as a direct replacement for ATC-35?

A: Yes. Both parts share identical current rating (35 A), voltage rating (32 V DC), fuse type (automotive), response time (fast blow), package configuration (blade, ATO/ATC), breaking capacity (1 kA), and physical dimensions. Direct substitution is supported.

Q: What determines if a part qualifies as a substitute for ATC-35?

A: Substitution requires exact equivalence across current rating, voltage rating, fuse type, response time, package type, breaking capacity, mounting configuration, and physical dimensions. Any deviation in these parameters disqualifies a part from substitution.

Q: Are there differences in RoHS compliance between ATC-35 and BK/ATC-35?

A: ATC-35 is RoHS Compliant, while BK/ATC-35 is ROHS3 Compliant. Both meet RoHS requirements; ROHS3 represents a more recent compliance designation. This distinction does not affect electrical or mechanical interchangeability.

Q: What is the breaking capacity of these fuses?

A: Both ATC-35 and BK/ATC-35 have a breaking capacity of 1 kA at rated voltage (32 V DC).

Q: Do these fuses require a specific holder type?

A: Yes. Both parts require a holder for installation. The ATO/ATC blade configuration specifies the holder type required for proper operation.
