Substitute Part Grouping Explanation

Substitution eligibility for the 0ATO015.ZXPRO is determined by strict equivalence across the following critical parameters:

• Current Rating: 15 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Fuse Type: Automotive blade fuse (ATO/ATC form factor)
• Response Time: Fast Blow characteristic
• Physical Dimensions: 0.750" L x 0.200" W x 0.480" H
• Approval Certifications: CSA, SAE, UL compliance

The substitute part 0ATO015.VXPK meets all electrical and mechanical parameters. The primary difference is packaging configuration: the main part is supplied in single-unit box packaging, while the substitute is supplied in 5-pack box configuration. Both parts are manufactured by Littelfuse Inc. within the ATO® series and maintain identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 0ATO015.VXPK is a direct electrical and mechanical equivalent to the 0ATO015.ZXPRO. Both parts carry identical certifications (CSA, SAE, UL) and comply with ROHS3 requirements. Selection between these parts should be based on packaging requirements and product lifecycle status.

The main part (0ATO015.ZXPRO) maintains active product status and is recommended for new designs and ongoing production applications. The substitute part (0ATO015.VXPK) is classified as obsolete and should be considered only when single-unit packaging is not available and multi-unit packaging is acceptable for the application. Both parts are currently in stock and available for immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can 0ATO015.VXPK be used as a direct replacement for 0ATO015.ZXPRO?

A: Yes. Both parts are electrically and mechanically identical. The 0ATO015.VXPK is supplied in 5-pack configuration while the main part is supplied in single-unit box packaging. The fuse element, electrical ratings, physical dimensions, and certifications are identical.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging. The 0ATO015.ZXPRO is supplied as a single fuse in box packaging. The 0ATO015.VXPK is supplied as five fuses in a single box. All electrical and mechanical specifications are identical.
