Key Parameters

Substitute Part Grouping Explanation

The substitute part 0294120.H is classified as a parametric equivalent based on the following critical parameters that determine substitutability:

• Current Rating: 120 A (identical)
• Voltage Rating - DC: 32 V (identical)
• Response Time: Slow Blow (identical)
• Mounting Type: Bolt Mount (identical)
• Package / Case: Auto Link (identical)
• Physical Dimensions: 0.898" L x 0.638" W x 0.866" H (identical)
• Fuse Type: Automotive (identical)

Both parts originate from Littelfuse Inc. and maintain identical electrical and mechanical specifications. The primary distinction is the series designation: PAL™ 283 for the main part and PAL™ 294 for the substitute. This series variation does not affect functional compatibility within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can 0294120.H be used as a direct replacement for 0283120.MXJ-B?

A: Yes. Both parts share identical current rating (120 A), voltage rating (32 V DC), response time (Slow Blow), mounting type (Bolt Mount), package type (Auto Link), and physical dimensions. The series designation difference (PAL™ 283 versus PAL™ 294) does not affect functional compatibility.

Q: Are there any physical installation differences between these parts?

A: No. Both parts feature identical bolt mount installation and Auto Link packaging with matching dimensions of 0.898" L x 0.638" W x 0.866" H (22.81mm x 16.20mm x 22.00mm).

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and maintain unlimited moisture sensitivity rating (MSL 1).

Q: What is the basis for substitution between these part numbers?

A: Substitution is based on matching electrical specifications (120 A, 32 V DC, Slow Blow response), mechanical compatibility (Bolt Mount, Auto Link package), and identical physical dimensions. Both parts are manufactured by Littelfuse Inc. and maintain active product status.
