Littelfuse 0695020.U Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0695020.U is a 20A automotive fuse rated for 32V DC operation with slow-blow response characteristics. This component is designed for automotive electrical circuit protection and requires a compatible fuse holder for installation. The part maintains active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, packaging preferences, or application-specific holder compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 0695020.U is determined by strict equivalence across the following critical parameters:

• Current Rating: 20 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Automotive (exact match required)
• Package / Case: Auto Link (exact match required)
• Breaking Capacity @ Rated Voltage: 1 kA (exact match required)
• Operating Temperature Range: -40°C to 125°C (exact match required)
• Physical Dimensions: 0.421" L x 0.244" W x 0.689" H (exact match required)

The substitute part MCAS020.XP meets all electrical and mechanical equivalence criteria. Differences in series designation (MCASE™ 695 versus MCASE™) and packaging format (Bulk versus 1 PC Card) do not affect functional compatibility or circuit protection performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 0695020.U and MCAS020.XP are active Littelfuse products with identical electrical protection characteristics and full regulatory compliance. Selection between these parts is based on packaging and inventory availability rather than functional performance differences. The 0695020.U is supplied in bulk packaging, while MCAS020.XP is supplied in 1 PC card format. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current automotive and industrial standards. The choice between these equivalents does not affect circuit protection performance, thermal characteristics, or breaking capacity.

Frequently Asked Questions (FAQ)

Q: Can MCAS020.XP be used as a direct replacement for 0695020.U in automotive applications?

A: Yes. Both parts are electrically and mechanically equivalent with identical current ratings (20A), voltage ratings (32V DC), response characteristics (slow blow), and physical dimensions. Both require the same Auto Link holder type.

Q: What is the difference between the 0695020.U and MCAS020.XP?

A: The primary differences are series designation (MCASE™ 695 versus MCASE™) and packaging format (Bulk versus 1 PC Card). These differences do not affect electrical performance or circuit protection capability.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both the 0695020.U and MCAS020.XP operate across the identical temperature range of -40°C to 125°C.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.10.0040.

Q: What holder type is required for installation?

A: Both parts require a compatible Auto Link fuse holder. The physical dimensions (0.421" L x 0.244" W x 0.689" H) are identical, ensuring holder compatibility.

Q: Is there a difference in breaking capacity between these parts?

A: No. Both parts have an identical breaking capacity of 1 kA at rated voltage.
