Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LJCA030.XP are identified based on exact matching of the following critical parameters:

• Current Rating: 30 A
• Voltage Rating - AC: 32 V
• Voltage Rating - DC: 32 V
• Response Time: Slow Blow
• Fuse Type: Automotive
• Package / Case: Auto Link
• Size / Dimension: 0.571" L x 0.472" W x 0.630" H (14.50mm x 12.00mm x 16.00mm)
• Series: JCASE®
• Mounting Type: Requires Holder

The LJCA030.X is classified as a parametric equivalent because it maintains identical electrical ratings, mechanical dimensions, response characteristics, and packaging specifications. Both parts are manufactured by Littelfuse Inc. within the same JCASE® series and are suitable for direct substitution in automotive fuse holder applications.

Frequently Asked Questions (FAQ)

Q: Can LJCA030.X be used as a direct replacement for LJCA030.XP?

A: Yes. Both parts are parametric equivalents with identical current ratings (30 A), voltage ratings (32 V AC/DC), response time (slow blow), package type (Auto Link), and physical dimensions. They are interchangeable in automotive fuse holder applications.

Q: What determines if a fuse is a suitable substitute?

A: Substitution is based on matching current rating, voltage rating (both AC and DC), response time, fuse type, package configuration, physical dimensions, and mounting requirements. All these parameters must be identical for direct interchangeability.

Q: Are there any compliance differences between LJCA030.XP and LJCA030.X?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant and REACH Unaffected status.

Q: What is the significance of the Auto Link package?

A: The Auto Link package is a specific mechanical configuration for automotive fuses that requires a dedicated fuse holder. Both substitute parts use this same package type, ensuring physical and electrical compatibility with the same holder.

Q: Does the pink color have functional significance?

A: The pink color is a visual indicator of the 30 A current rating in automotive fuse standards. Both parts share this color specification.
