Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0695900.UX4 is determined by strict equivalence across the following critical parameters:

• Current Rating: 900 A (exact match required)
• Voltage Rating: 32 V DC (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: Auto Link (exact match required)
• Breaking Capacity: 1 kA @ Rated Voltage (exact match required)
• Operating Temperature Range: -40°C to 125°C (exact match required)
• Physical Dimensions: 10.70mm × 6.20mm × 17.50mm (exact match required)
• Series: MCASE™ 695 (exact match required)

The substitute part 0695900.PXPS meets all electrical and mechanical parameters. The only difference is packaging configuration (Bulk versus standard packaging), which does not affect functional compatibility or performance in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0695900.UX4 and 0695900.PXPS are active production parts from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and procurement logistics. Both parts maintain ROHS3 compliance and are suitable for automotive applications requiring 900A protection at 32V DC. The choice between standard and bulk packaging does not affect functional performance or compatibility with Auto Link holders.

Frequently Asked Questions (FAQ)

Q: Can 0695900.PXPS be used as a direct replacement for 0695900.UX4?

A: Yes. Both parts are electrically and mechanically identical, with matching current ratings (900A), voltage ratings (32V DC), response characteristics (Slow Blow), and physical dimensions (10.70mm × 6.20mm × 17.50mm). The only difference is packaging configuration.

Q: What is the significance of the packaging difference between these parts?

A: The 0695900.UX4 uses standard packaging while 0695900.PXPS uses bulk packaging. This affects order quantities and storage considerations but does not impact electrical performance or mechanical compatibility with Auto Link fuse holders.

Q: Are both parts suitable for the same automotive applications?

A: Yes. Both parts are classified as automotive fuses with identical specifications, operating temperature ranges (-40°C to 125°C), and breaking capacity (1 kA @ rated voltage). They are interchangeable for all automotive circuit protection applications requiring these specifications.

Q: What certifications apply to both substitute parts?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. Both are part of the MCASE™ 695 series and maintain active product status.

Q: Can these fuses be used interchangeably in existing Auto Link holders?

A: Yes. Both parts use the Auto Link package configuration with identical physical dimensions, ensuring mechanical compatibility with existing Auto Link fuse holders.
