ATC-30 Equivalent & Substitute Parts

Part Overview

The ATC-30 is a 30 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 and is RoHS compliant, making it suitable for current automotive applications where circuit protection at 30 A is required.

Substitute parts are identified when electrical and mechanical parameters align with the original specification, ensuring functional equivalence in automotive fuse applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATC-30 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part BK/ATC-30 qualifies as a parametric equivalent because it maintains identical specifications in the following key areas:

• Current Rating: 30 A
• Voltage Rating - DC: 32 V
• Fuse Type: Automotive
• Response Time: Fast Blow
• Package / Case: Blade, ATO/ATC
• Breaking Capacity @ Rated Voltage: 1 kA
• Physical Dimensions: 0.760" L x 0.207" W x 0.492" H (19.30mm x 5.25mm x 12.50mm)
• Mounting Type: Requires Holder
• Approval Agency: UL

Both parts are manufactured by Eaton - Bussmann Electrical Division and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both ATC-30 and BK/ATC-30 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: ATC-30 has 917 pcs in stock; BK/ATC-30 has 1401 pcs in stock
• RoHS compliance level: ATC-30 is RoHS Compliant; BK/ATC-30 is ROHS3 Compliant
• REACH status: BK/ATC-30 specifies REACH Unaffected status

Both parts carry UL approval and maintain identical breaking capacity, voltage rating, current rating, and physical dimensions required for automotive fuse holder applications.

Frequently Asked Questions (FAQ)

Q: Can BK/ATC-30 be used as a direct replacement for ATC-30?

A: Yes. Both parts are parametric equivalents with identical current rating (30 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 (0.760" L x 0.207" W x 0.492" H).

Q: Are there any differences in compliance between ATC-30 and BK/ATC-30?

A: Both parts are UL approved and RoHS compliant. BK/ATC-30 specifies ROHS3 Compliant status and REACH Unaffected designation, while ATC-30 lists RoHS Compliant status without additional REACH specification.

Q: What mounting configuration is required for these fuses?

A: Both ATC-30 and BK/ATC-30 require a holder for installation. They use the ATO/ATC blade configuration standard in automotive electrical systems.

Q: Do these fuses have the same physical dimensions?

A: Yes. Both parts measure 0.760" L x 0.207" W x 0.492" H (19.30mm x 5.25mm x 12.50mm), ensuring compatibility with standard ATO/ATC fuse holders.

Q: What is the breaking capacity of these fuses?

A: Both ATC-30 and BK/ATC-30 have a breaking capacity of 1 kA at rated voltage, meeting automotive circuit protection requirements.
