ATM-10 Equivalent & Substitute Parts

Part Overview

The ATM-10 is a 10 A automotive blade fuse rated for 32 V DC operation with fast-blow response characteristics. Manufactured by Eaton - Bussmann Electrical Division, this miniature blade fuse is designed for automotive electrical circuits requiring overcurrent protection. The part is currently active in production with 1020 pieces available in bulk packaging. Substitute parts are identified based on identical electrical ratings, mechanical dimensions, and functional specifications to ensure direct compatibility in automotive fuse holder applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ATM-10 are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain identical:

• Current Rating: 10 A
• Voltage Rating - DC: 32 V
• Fuse Type: Automotive
• Response Time: Fast Blow
• Package / Case: Blade, Miniature
• Breaking Capacity @ Rated Voltage: 1 kA
• Physical Dimensions: 0.430" L x 0.150" W x 0.347" H (10.92mm x 3.81mm x 8.81mm)
• Mounting Type: Requires Holder

Parts meeting all these specifications are classified as parametric equivalents and are suitable for direct substitution in applications designed for the ATM-10.

Parameter Comparison

Engineering Selection Recommendations

Both the ATM-10 and BK/ATM-10 are active production parts manufactured by Eaton - Bussmann Electrical Division with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

ATM-10: Suitable for applications requiring RoHS Compliant certification. Current inventory: 1020 pieces.

BK/ATM-10: Suitable for applications requiring ROHS3 Compliant certification with REACH Unaffected status. Current inventory: 2612 pieces. This part provides enhanced regulatory compliance documentation for European market applications.

Both parts are functionally interchangeable in automotive fuse holder applications requiring 10 A, 32 V DC fast-blow protection. Selection should be based on specific regulatory compliance requirements and inventory availability for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the BK/ATM-10 be used as a direct replacement for the ATM-10?

A: Yes. Both parts share identical electrical ratings (10 A, 32 V DC), response characteristics (fast-blow), mechanical dimensions (0.430" L x 0.150" W x 0.347" H), and breaking capacity (1 kA). The BK/ATM-10 provides ROHS3 compliance in addition to RoHS compliance.

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

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. Both certifications indicate compliance with hazardous substance limitations; ROHS3 reflects the current regulatory standard.

Q: Are these fuses compatible with all automotive fuse holders rated for miniature blade fuses?

A: These fuses are designed for miniature blade fuse holders. Compatibility depends on the holder's specifications. The physical dimensions (0.430" L x 0.150" W x 0.347" H) and blade configuration must match the holder design.

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

A: Fast-blow fuses interrupt circuit current rapidly when overcurrent conditions occur, typically within milliseconds. This characteristic is suitable for circuits requiring immediate protection against short circuits and overcurrent events.

Q: Can these 32 V DC rated fuses be used in AC circuits?

A: The ATM-10 and BK/ATM-10 are rated for 32 V DC operation. Use in AC circuits requires verification that the application voltage and circuit characteristics align with automotive fuse specifications for the intended use.

Q: What is the breaking capacity specification?

A: Breaking capacity of 1 kA indicates the maximum current the fuse can safely interrupt at its rated voltage (32 V DC) without failure or hazard.
