Key Parameters

Substitute Part Grouping Explanation

The substitute part 0293525.H is classified as a parametric equivalent based on the following matching criteria:

• Current Rating: 25 A (identical)
• Voltage Rating - DC: 32 V (identical)
• Fuse Type: Automotive (identical)
• Response Time: Slow Blow (identical)
• Package / Case: Auto Link (identical)
• Mounting Type: Requires Holder (identical)
• Physical Dimensions: 0.906" L x 0.646" W x 1.205" H (identical)
• Series: PAL™ 293 (identical)
• Color: Brown (identical)
• RoHS Status: ROHS3 Compliant (identical)

The primary distinction between these parts is packaging configuration: the main part (0293525.U) is supplied as a unit, while the substitute (0293525.H) is supplied in bulk packaging (100 pack).

Parameter Comparison

Engineering Selection Recommendations

The 0293525.H serves as a direct functional substitute for the obsolete 0293525.U. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters: 25A current rating, 32V DC voltage rating, slow-blow response characteristic, Auto Link package format, and physical dimensions.

The substitute part maintains active product status, ensuring continued availability and supply chain reliability. Both parts comply with ROHS3 requirements, supporting environmental and regulatory compliance objectives.

Selection between these parts should be based on packaging requirements: the 0293525.U configuration is appropriate for single-unit applications, while the 0293525.H bulk packaging (100 pack) is suitable for higher-volume procurement or inventory consolidation scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 0293525.H be used as a direct replacement for the 0293525.U?

A: Yes. Both parts are electrically and mechanically identical, with matching current ratings (25A), voltage ratings (32V DC), response characteristics (slow-blow), package formats (Auto Link), and physical dimensions. The only difference is packaging configuration.

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

A: The 0293525.U is supplied as a single unit, while the 0293525.H is supplied in bulk packaging containing 100 pieces. The electrical and mechanical performance of the fuse element itself is identical in both configurations.

Q: Does the Auto Link package format require special installation considerations?

A: Yes. Both parts require a compatible Auto Link fuse holder for installation. The physical dimensions (23.00mm x 16.40mm x 30.60mm) must be verified against the holder specifications to ensure proper fit and electrical contact.

Q: Are there any compliance differences between these substitute parts?

A: No. Both parts maintain identical RoHS3 compliance status. The substitute part (0293525.H) is currently active in production, while the original part (0293525.U) is obsolete.

Q: What factors determine substitutability for automotive fuses in this category?

A: Substitutability is determined by matching current rating, voltage rating, response time characteristic, package format, physical dimensions, and mounting requirements. All these parameters are identical between the 0293525.U and 0293525.H.
