MIC207.5VP Automotive Micro Blade Fuse - Equivalent & Substitute Parts

Part Overview

The MIC207.5VP is a 7.5 A automotive micro blade fuse rated for 32 V DC operation, manufactured by Littelfuse Inc. under the MICRO2™ series. 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 ratings, mechanical dimensions, and operational parameters align with the main part specification, ensuring direct interchangeability in automotive fuse applications.

Substitute Part Grouping Explanation

Substitution eligibility for the MIC207.5VP is determined by strict equivalence across the following parameters:

Current Rating: 7.5 A (exact match required)
Voltage Rating (DC): 32 V (exact match required)
Package / Case: Blade, Micro (exact match required)
Fuse Type: Automotive (exact match required)
Mounting Type: Requires Holder (exact match required)
Operating Temperature Range: -40°C to 125°C (exact match required)
Physical Dimensions: 0.358" L × 0.150" W × 0.311" H (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)

All four substitute parts (032707.5LXS, 032707.5UXS, 032707.5YX2S, and MIC307.5VP) meet these criteria and are manufactured by Littelfuse Inc. Variations in series designation (MICRO2™ versus MICRO3™) and secondary parameters such as melting I²t and DC cold resistance do not affect functional interchangeability within automotive circuit protection applications.

Engineering Selection Recommendations

All substitute parts maintain Active product status with full RoHS3 compliance and REACH unaffected designation, matching the regulatory and environmental compliance profile of the MIC207.5VP. Selection among these equivalents may be based on inventory availability and lead time considerations, as all parts satisfy identical electrical and mechanical requirements for automotive micro blade fuse applications.

The MIC307.5VP represents a series upgrade from MICRO2™ to MICRO3™ while maintaining complete parameter equivalence. The 032707.5 series variants (LXS, UXS, YX2S) provide alternative part numbering within the MICRO2™ 327 series designation.

Frequently Asked Questions (FAQ)

Q: Can MIC207.5VP be directly replaced with 032707.5LXS, 032707.5UXS, or 032707.5YX2S?

A: Yes. All three parts are direct equivalents meeting identical electrical ratings (7.5 A, 32 V DC), mechanical dimensions (Blade, Micro package), and operational specifications. They are interchangeable in automotive circuit protection applications.

Q: What is the difference between MIC207.5VP and MIC307.5VP?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary distinction is series designation: MIC207.5VP belongs to the MICRO2™ series, while MIC307.5VP belongs to the MICRO3™ series. This represents a product line evolution with no impact on interchangeability.

Q: Are all substitute parts compatible with the same fuse holder?

A: Yes. All substitute parts share identical physical dimensions (0.358" L × 0.150" W × 0.311" H) and Blade, Micro package specification, ensuring compatibility with any fuse holder designed for the MIC207.5VP.

Q: Do the substitute parts have the same temperature operating range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 125°C, matching the MIC207.5VP specification.
