Substitute Part Grouping Explanation

Substitution for the Littelfuse 0293840.U is determined by strict equivalence across the following critical parameters:

• Current Rating: 40 A
• Voltage Rating - DC: 32 V
• Response Time: Slow Blow
• Package / Case: Auto Link
• Fuse Type: Automotive
• Series: PAL™ 293
• Physical Dimensions: 0.906" L x 0.646" W x 1.205" H (23.00mm x 16.40mm x 30.60mm)

The substitute parts identified below maintain identical electrical and mechanical specifications. Differences exist only in packaging configuration (bulk versus individual) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

Both 0293840.H and 0293040.H are active product alternatives to the obsolete 0293840.U. Selection between these substitutes should be based on packaging requirements and procurement volume:

• 0293840.H: Active status, bulk packaging, 780 pcs available. Recommended for production volumes requiring bulk supply.
• 0293040.H: Active status, bulk packaging, 907 pcs available. Recommended for production volumes requiring bulk supply.

Both substitutes maintain full electrical and mechanical compatibility with the original 0293840.U specification. All three parts are ROHS3 compliant and carry identical dimensional, electrical, and functional characteristics within the PAL™ 293 series.

Frequently Asked Questions (FAQ)

Q: Can 0293840.H and 0293040.H be used interchangeably with 0293840.U?

A: Yes. All three parts share identical electrical specifications (40A, 32VDC, Slow Blow response), mechanical dimensions (0.906" L x 0.646" W x 1.205" H), and Auto Link package configuration. The primary differences are product status and packaging format.

Q: What is the difference between the substitute parts?

A: The 0293840.H and 0293040.H are parametric equivalents differing only in packaging (both bulk) and inventory availability. Both are active products suitable for replacing the obsolete 0293840.U.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (individual versus bulk) does not affect electrical or mechanical performance. Selection should be based on procurement volume and supply chain requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. The 0293840.U, 0293840.H, and 0293040.H are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Can these fuses be used without a holder?

A: No. All three parts require a compatible Auto Link fuse holder for installation and operation.
