Littelfuse 0695015.PX4 Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0695015.PX4 is a 15A automotive fuse rated for 32V DC operation, designed for automotive electrical systems requiring holder-mounted protection. This MCASE™ 695 series fuse is an active product with full RoHS3 compliance and operates across the temperature range of -40°C to 125°C. Substitute parts are identified when packaging configurations differ or when inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0695015.PX4 are qualified based on matching the following critical parameters: current rating (15 A), voltage rating (32 V DC), fuse type (Automotive), package type (Auto Link), mounting configuration (Requires Holder), breaking capacity (1 kA), physical dimensions (0.421" L x 0.244" W x 0.689" H), operating temperature range (-40°C to 125°C), and RoHS3 compliance status. Substitutes differ only in packaging configuration (Bulk vs. Card) and response time designation, which do not affect electrical or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0695015.PX4, 0695015.U, and MCAS015.XP—are active products manufactured by Littelfuse Inc. with full RoHS3 compliance. Selection between these parts is determined by packaging and inventory requirements rather than electrical performance. The 0695015.PX4 and 0695015.U are both MCASE™ 695 series components with identical electrical specifications. The MCAS015.XP is supplied on a single-piece card format and belongs to the broader MCASE™ series. All three parts meet the same breaking capacity, voltage, current, and temperature specifications required for automotive fuse applications.

Frequently Asked Questions (FAQ)

Q: Can 0695015.U be used as a direct replacement for 0695015.PX4?

A: Yes. Both parts share identical electrical ratings (15 A, 32 V DC), mechanical dimensions (0.421" L x 0.244" W x 0.689" H), package type (Auto Link), and operating temperature range (-40°C to 125°C). The difference is packaging configuration: 0695015.U is supplied in Bulk format while 0695015.PX4 uses standard packaging.

Q: What is the difference between 0695015.U and MCAS015.XP?

A: Both parts have identical electrical specifications (15 A, 32 V DC, 1 kA breaking capacity) and physical dimensions. The primary differences are series designation (MCASE™ 695 vs. MCASE™) and packaging format (Bulk vs. 1 PC Card). Electrical and mechanical compatibility in the application is equivalent.

Q: Are all three parts suitable for the same automotive circuit?

A: Yes. All three parts meet the same electrical requirements: 15 A current rating, 32 V DC voltage rating, Auto Link package type, and 1 kA breaking capacity. Physical dimensions and mounting requirements are identical across all three parts.

Q: What does "Requires Holder" mean for mounting?

A: All three parts are designed for use with an automotive fuse holder. The fuse element itself does not mount directly to the circuit board or harness; it must be installed in a compatible Auto Link fuse holder.

Q: Are there any temperature or compliance differences between these parts?

A: No. All three parts operate across the identical temperature range (-40°C to 125°C) and carry full RoHS3 compliance certification.
