Substitute Part Grouping Explanation

Substitution eligibility for the 0283070.MXJ is determined by strict equivalence across the following critical parameters:

• Current Rating: 70 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Automotive (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Auto Link (exact match required)
• Physical Dimensions: 0.898" L x 0.638" W x 0.866" H (exact match required)
• Color: Brown (exact match required)
• Compliance: RoHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute part 0295070.H meets all electrical and mechanical criteria for direct substitution. The primary distinction between the main part and substitute is the series designation (PAL™ 283 versus PAL™ 295) and packaging quantity configuration (bulk versus 100-pack), neither of which affects functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 0295070.H replace the 0283070.MXJ in automotive circuits?

A: Yes. Both parts are electrically and mechanically identical with matching 70 A current rating, 32 V DC voltage rating, slow-blow response, Auto Link package format, and physical dimensions. The series designation difference (PAL™ 283 versus PAL™ 295) does not affect functional compatibility.

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

A: The primary difference is packaging configuration. The 0283070.MXJ is supplied in bulk packaging, while the 0295070.H is supplied in 100-pack configuration. All electrical and mechanical parameters remain identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 0283070.MXJ and 0295070.H are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for automotive applications.

Q: Do these fuses have identical physical dimensions?

A: Yes. Both parts measure 0.898" L x 0.638" W x 0.866" H (22.81mm x 16.20mm x 22.00mm) and use the Auto Link package format, ensuring mechanical compatibility in bolt mount applications.

Q: What response time do these fuses provide?

A: Both parts provide slow-blow response characteristics, designed to tolerate temporary inrush currents while protecting against sustained overcurrent conditions in automotive circuits.
