Littelfuse 0327005.ZXS Automotive Micro Blade Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0327005.ZXS is a 5 A, 32 V DC automotive micro blade fuse designed for circuit protection in automotive applications. This part is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and component sourcing. The MICRO2™ 327 series fuse requires a compatible holder for installation and operates across an extended temperature range of -40°C to 125°C. Direct substitutes and parametric equivalents are available from Littelfuse's active product lines, including the MICRO2™ and MICRO3™ series variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0327005.ZXS is determined by strict equivalence across the following critical parameters:

• Current Rating: All substitutes must be rated at 5 A
• Voltage Rating (DC): All substitutes must be rated at 32 V DC
• Package / Case: All substitutes must use Blade, Micro form factor
• Mounting Type: All substitutes must require a compatible holder
• Operating Temperature Range: All substitutes must support -40°C to 125°C
• Physical Dimensions: All substitutes must match 0.358" L x 0.150" W x 0.311" H (9.10mm x 3.80mm x 7.90mm)
• Breaking Capacity: All substitutes must maintain 1 kA breaking capacity
• Melting I²t: All substitutes must maintain I²t value of 17
• RoHS Compliance: All substitutes must maintain ROHS3 compliance

The substitute parts are grouped into two categories: direct manufacturer substitutes (0327005.YX2S, 0327005.UXS) and parametric equivalents from alternative series (MIC2005.VP, MIC3005.VP, 0327005.LXS). All listed substitutes meet the electrical and mechanical requirements for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete 0327005.ZXS, the following selection criteria apply:

Primary Substitutes (Same Series - MICRO2™ 327):

• 0327005.YX2S and 0327005.UXS are direct substitutes within the same MICRO2™ 327 series. Both parts are in active production status and maintain full electrical and mechanical compatibility. 0327005.UXS is preferred where breaking capacity specification is critical, as it explicitly documents 1 kA capacity.

Secondary Substitutes (Alternative Series):

• 0327005.LXS is a parametric equivalent within the MICRO2™ 327 series, available in bulk packaging with active product status.
• MIC2005.VP and MIC3005.VP are parametric equivalents from the MICRO2™ and MICRO3™ series respectively. Both maintain electrical equivalence and active production status. These parts are suitable for applications where series designation is not a constraint.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing supply chain and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 0327005.YX2S directly replace 0327005.ZXS in existing designs? A: Yes. 0327005.YX2S is a direct substitute within the same MICRO2™ 327 series. It matches all critical electrical parameters (5 A, 32 V DC), physical dimensions (0.358" L x 0.150" W x 0.311" H), and operating temperature range (-40°C to 125°C). The part is in active production status.

Q: What is the difference between 0327005.UXS and 0327005.YX2S? A: Both are MICRO2™ 327 series fuses with identical electrical ratings and physical dimensions. The primary difference is packaging: 0327005.YX2S is supplied in bulk packaging, while 0327005.UXS is also bulk packaged. Both are active products suitable for direct substitution.

Q: Are MIC2005.VP and MIC3005.VP compatible with existing fuse holders designed for 0327005.ZXS? A: Yes. MIC2005.VP and MIC3005.VP are parametric equivalents with identical Blade, Micro package specifications and physical dimensions (0.358" L x 0.150" W x 0.311" H). They are compatible with any holder designed for micro blade fuses of this size. The series designation (MICRO2™ versus MICRO3™) does not affect mechanical compatibility.

Q: Why is 0327005.LXS listed as a substitute if it has a different color (Orange vs. Tan)? A: Color designation reflects manufacturing or packaging variants but does not affect electrical function or mechanical compatibility. 0327005.LXS maintains all critical electrical parameters (5 A, 32 V DC, 1 kA breaking capacity, I²t of 17) and physical dimensions required for substitution. Color is a visual identifier only and does not impact circuit protection performance.

Q: What does "Requires Holder" mean for mounting type? A: All listed fuses require a compatible fuse holder for installation. The fuse does not solder directly to a PCB or mount independently. Ensure the existing fuse holder is rated for Blade, Micro form factor fuses before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (0327005.YX2S, 0327005.UXS, 0327005.LXS, MIC2005.VP, MIC3005.VP) are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original 0327005.ZXS.

Q: Which substitute should I choose for new designs? A: For new designs, select from active production parts: 0327005.YX2S, 0327005.UXS, 0327005.LXS, MIC2005.VP, or MIC3005.VP. All meet the specified electrical and mechanical requirements. Series selection (MICRO2™ 327, MICRO2™, or MICRO3™) depends on design documentation requirements; electrical performance is equivalent across all options.
