Key Parameters

Substitute Part Grouping Explanation

The JCAS025.XPA is classified as a parametric equivalent to JCAS025.X based on the following substitution criteria:

• Current Rating: 25 A (identical)
• Voltage Rating AC/DC: 32 V (identical)
• Response Time: Slow Blow (identical)
• Fuse Type: Automotive (identical)
• Package / Case: Auto Link (identical)
• Breaking Capacity: 1kA (identical)
• Physical Dimensions: 0.555" L x 0.472" W x 1.063" H (identical)
• Operating Temperature: -40°C ~ 125°C (identical)
• Series: JCASE® (identical)

Both parts are manufactured by Littelfuse Inc. and maintain active product status with ROHS3 compliance. The substitution is valid for direct replacement in automotive fuse holder applications where these electrical and mechanical specifications are required.

Parameter Comparison

Engineering Selection Recommendations

Both JCAS025.X and JCAS025.XPA are active products from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability or packaging preference, as both maintain ROHS3 compliance and are suitable for automotive fuse holder applications requiring 25A protection at 32V AC/DC. The JCAS025.XPA currently has higher inventory availability (1036 Pcs vs. 697 Pcs).

Frequently Asked Questions (FAQ)

Q: Can JCAS025.XPA be used as a direct replacement for JCAS025.X?

A: Yes. Both parts are parametric equivalents with identical current rating (25A), voltage rating (32V AC/DC), response time (Slow Blow), package type (Auto Link), breaking capacity (1kA), and physical dimensions. Direct substitution is valid in automotive fuse holder applications.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts maintain identical RoHS3 compliance status, REACH unaffected status, and ECCN/HTSUS classifications. Both are active products from the same manufacturer.

Q: What determines whether a fuse can substitute for JCAS025.X?

A: Substitution requires matching all critical parameters: 25A current rating, 32V AC and DC voltage ratings, Slow Blow response time, Auto Link package type, 1kA breaking capacity, and identical physical dimensions (0.555" L x 0.472" W x 1.063" H). Deviation in any of these parameters disqualifies a part from substitution.

Q: Does packaging format affect substitution eligibility?

A: No. Both JCAS025.X and JCAS025.XPA use identical Auto Link packaging and require the same fuse holder. Packaging format (Bulk) does not affect electrical or mechanical compatibility.

Q: What is the operating temperature range for these fuses?

A: Both parts operate across -40°C to 125°C, suitable for automotive environments including engine compartment applications.
