Parameter Comparison

Engineering Selection Recommendations

Both ATM-5 and BK/ATM-5 are active production parts from Eaton - Bussmann Electrical Division with identical electrical and mechanical specifications. The BK/ATM-5 carries ROHS3 Compliant certification, while the ATM-5 is RoHS Compliant. Both parts are REACH Unaffected and classified under ECCN EAR99. Selection between these parts depends on specific regulatory requirements for the end application. The BK/ATM-5 offers higher current inventory availability at 774 units compared to 707 units for the ATM-5.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical current rating (5A), voltage rating (32V DC), fuse type (Automotive), response time (Fast Blow), package type (Blade, Miniature), breaking capacity (1kA), and physical dimensions (0.430" L x 0.150" W x 0.347" H). Direct substitution is supported in automotive fuse holder applications.

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

A: ROHS3 Compliant indicates compliance with the latest RoHS 3 directive (2011/65/EU as amended by 2015/863/EU), which includes restrictions on additional substances. Both certifications confirm lead-free and hazardous substance compliance; ROHS3 represents the current regulatory standard.

Q: Are these fuses compatible with standard automotive miniature blade fuse holders?

A: Yes. Both parts are specified as Blade, Miniature type fuses requiring a holder. They are compatible with standard automotive miniature blade fuse holder receptacles.

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

A: Fast Blow indicates the fuse element melts quickly upon overcurrent conditions, typically within milliseconds. This response characteristic is standard for automotive circuit protection applications.

Q: Can these fuses be used in AC applications?

A: The specification indicates 5 A AC and 32 V DC rating. These fuses are rated for both AC and DC operation at the specified voltage levels.
