MCAS025.V Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The MCAS025.V is a 25A automotive fuse rated for 32V DC operation, manufactured by Littelfuse under the MCASE™ series. This slow-blow fuse is designed for automotive applications requiring a holder-mounted configuration with Auto Link packaging. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging quantities differ.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 0695025.L is classified as a parametric equivalent based on the following critical parameters that determine substitutability:

Current Rating: 25 A (identical) Voltage Rating - DC: 32 V (identical) Response Time: Slow Blow (identical) Fuse Type: Automotive (identical) Package / Case: Auto Link (identical) Breaking Capacity @ Rated Voltage: 1kA (identical) Operating Temperature Range: -40°C ~ 125°C (identical) Physical Dimensions: 0.421" L x 0.244" W x 0.689" H (identical)

Both parts belong to the Littelfuse MCASE™ series and share identical electrical and mechanical specifications. The primary difference is packaging quantity: MCAS025.V is supplied in single-piece card packaging, while 0695025.L is supplied in 50-piece box packaging.

Parameter Comparison

Engineering Selection Recommendations

Both MCAS025.V and 0695025.L are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

MCAS025.V is appropriate for applications requiring single-unit or low-quantity procurement with individual card packaging.

0695025.L is appropriate for high-volume applications or inventory consolidation where 50-piece box packaging provides cost efficiency and reduced handling.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance in automotive applications. The identical breaking capacity of 1kA at rated voltage and operating temperature range of -40°C to 125°C confirm functional equivalence for all automotive circuit protection applications within these specifications.

Frequently Asked Questions (FAQ)

Q: Can 0695025.L be used as a direct replacement for MCAS025.V?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (25A), voltage ratings (32V DC), response characteristics (Slow Blow), and physical dimensions. The only difference is packaging quantity.

Q: What is the significance of the MCASE™ series designation?

A: MCASE™ is the Littelfuse product series for automotive fuses. Both parts belong to this series, confirming their automotive-grade design and performance standards.

Q: Are there any temperature or environmental limitations that affect substitutability?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C and share identical RoHS3 and REACH compliance status.

Q: What does "Slow Blow" response time mean?

A: Slow Blow indicates the fuse has a delayed response to overcurrent conditions, allowing brief transient current spikes without opening. This characteristic is identical in both parts.

Q: Does packaging quantity affect electrical performance?

A: No. Packaging quantity (single-piece card versus 50-piece box) does not affect the electrical or mechanical performance of individual fuses. Selection should be based on procurement and inventory requirements.

Q: Are both parts suitable for automotive applications requiring 25A protection at 32V DC?

A: Yes. Both MCAS025.V and 0695025.L are automotive-grade fuses with identical specifications for 25A at 32V DC operation with 1kA breaking capacity.
