JCAS025.XPA Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The JCAS025.XPA is a 25A automotive fuse manufactured by Littelfuse Inc. in the JCASE® series. This slow-blow fuse is designed for automotive applications requiring 32V AC/DC protection with a breaking capacity of 1kA. The part is actively produced and widely stocked. Substitute parts may be required due to packaging preferences, regional availability, or inventory constraints while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The JCAS025.X is a parametric equivalent to the JCAS025.XPA. Substitution is valid based on the following criteria:

• Identical current rating: 25 A
• Identical voltage ratings: 32 V AC and 32 V DC
• Identical response time classification: Slow Blow
• Identical breaking capacity: 1 kA at rated voltage
• Identical operating temperature range: -40°C to 125°C
• Identical physical dimensions and Auto Link package configuration
• Same series designation: JCASE®
• Same fuse type classification: Automotive

The only difference between these parts is packaging format (Bulk vs. Box), which does not affect electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

Both JCAS025.XPA and JCAS025.X are active production parts from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and inventory availability:

• JCAS025.XPA: Bulk packaging format, 1036 units in stock
• JCAS025.X: Box packaging format, 697 units in stock

From an engineering perspective, either part is suitable for automotive 25A fuse applications at 32V AC/DC with slow-blow response characteristics. The choice between them is a procurement and logistics decision, not a technical one.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. They share the same current rating (25A), voltage ratings (32V AC/DC), response time (Slow Blow), breaking capacity (1kA), operating temperature range (-40°C to 125°C), physical dimensions, and Auto Link package configuration.

Q: What is the difference between JCAS025.XPA and JCAS025.X?

A: The only difference is the packaging format. JCAS025.XPA is supplied in Bulk packaging, while JCAS025.X is supplied in Box packaging. This does not affect the fuse's electrical performance or mechanical compatibility.

Q: Are both parts compliant with automotive standards?

A: Both parts are classified as automotive fuses and are ROHS3 compliant and REACH unaffected. Both are active production parts from Littelfuse Inc.

Q: Will either part fit in the same automotive fuse holder?

A: Yes. Both parts have identical Auto Link package configuration and physical dimensions (0.555" L × 0.472" W × 1.063" H), ensuring compatibility with the same fuse holders.

Q: Which part should I select for new designs?

A: Either part is acceptable for new designs. Selection should be based on packaging preference and supplier availability. Both are active production parts with equivalent technical specifications.
