MIC3015.VP Equivalent & Substitute Parts

Part Overview

The MIC3015.VP is a 15 A automotive blade fuse rated for 32 V DC operation, manufactured by Littelfuse in the MICRO3™ series. This component is designed for automotive electrical systems requiring overcurrent protection in blade-type fuse holders. 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 original specification, enabling direct replacement in automotive fuse applications.

Substitute Part Grouping Explanation

Substitution eligibility for the MIC3015.VP is determined by strict equivalence across the following parameters:

Current Rating: 15 A (exact match required)
Voltage Rating (DC): 32 V (exact match required)
Fuse Type: Automotive (exact match required)
Package / Case: Blade, Micro (exact match required)
Mounting Type: Requires Holder (exact match required)
Operating Temperature Range: -40°C ~ 125°C (exact match required)
Physical Dimensions: 0.358" L x 0.150" W x 0.311" H / 9.10mm x 3.80mm x 7.90mm (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

All four substitute parts meet these criteria. Variations in series designation (MICRO2™ 327 vs. MICRO3™) and secondary parameters such as melting I²t and DC cold resistance do not affect substitution eligibility when primary electrical and mechanical specifications are identical.

Engineering Selection Recommendations

All four substitute parts—0327015.LXS, 0327015.UXS, 0327015.YX2S, and MIC2015.VP—are direct equivalents to the MIC3015.VP based on electrical and mechanical parameter alignment. Each part maintains Active product status and full compliance with RoHS3 and REACH requirements.

Selection among these equivalents may be based on inventory availability and lead time considerations. The 0327015.LXS variant offers the highest inventory level at 14,725 pieces. The 0327015.UXS and 0327015.YX2S variants are available in quantities of 1,278 and 3,368 pieces respectively. The MIC2015.VP variant is available in 1,096 pieces.

All parts are suitable for direct substitution in automotive fuse applications requiring 15 A protection at 32 V DC with Blade, Micro package configuration.

Frequently Asked Questions (FAQ)

Q: Can MIC2015.VP replace MIC3015.VP in automotive applications?

A: Yes. Both parts share identical electrical ratings (15 A, 32 V DC), fuse type (Automotive), package configuration (Blade, Micro), and operating temperature range (-40°C ~ 125°C). The primary difference is series designation (MICRO2™ vs. MICRO3™), which does not affect functional compatibility.

Q: What is the difference between the 0327015 series variants?

A: The 0327015.LXS, 0327015.UXS, and 0327015.YX2S variants are all MICRO2™ 327 series fuses with identical electrical and mechanical specifications. Secondary parameters such as melting I²t (189 for all three) and DC cold resistance (0.0049 Ohms or 4.9 mOhms, equivalent values) are provided but do not affect substitution eligibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—0327015.LXS, 0327015.UXS, 0327015.YX2S, and MIC2015.VP—are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the MIC3015.VP.

Q: Do physical dimensions vary among substitute parts?

A: No. All substitute parts maintain identical physical dimensions of 0.358" L x 0.150" W x 0.311" H (9.10mm x 3.80mm x 7.90mm), ensuring mechanical compatibility with existing fuse holders designed for the MIC3015.VP.

Q: Is breaking capacity a factor in substitution?

A: Breaking capacity is specified as 1 kA for MIC3015.VP, 0327015.LXS, 0327015.UXS, and MIC2015.VP. The 0327015.YX2S variant does not specify breaking capacity in the provided data. All parts meet the electrical protection requirements for automotive blade fuse applications.
