Littelfuse 0ATO004.VP Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0ATO004.VP is a 4 A automotive blade fuse rated for 32 V AC/DC operation. This fast-blow fuse is designed for automotive electrical circuits requiring holder-based mounting in the ATO/ATC blade format. The part is actively manufactured and maintains full compliance with RoHS3, REACH, and automotive safety standards (CSA, SAE, UL). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category and voltage class.

Key Parameters

Substitute Part Grouping Explanation

The Littelfuse 0ATO004.V qualifies as a parametric equivalent to the 0ATO004.VP based on the following critical substitution criteria:

• Current Rating: 4 A (identical)
• Voltage Rating: 32 V AC / 32 V DC (identical)
• Fuse Type: Automotive (identical)
• Response Time: Fast Blow (identical)
• Package / Case: Blade, ATO/ATC (identical)
• Mounting Type: Requires Holder (identical)
• Physical Dimensions: 0.750" L x 0.200" W x 0.480" H (identical)
• Color: Pink (identical)
• RoHS Status: ROHS3 Compliant (identical)
• REACH Status: REACH Unaffected (identical)

Both parts are manufactured by Littelfuse Inc. and maintain active product status. The primary difference is packaging configuration: the 0ATO004.VP is supplied in 5-pack card format, while the 0ATO004.V is supplied in bulk format. This distinction does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ATO004.VP and 0ATO004.V are active products from Littelfuse Inc. with full RoHS3 and REACH compliance. Selection between these parts should be based on packaging requirements and inventory availability rather than electrical or mechanical performance.

The 0ATO004.VP (5-pack card format) is suitable for applications requiring pre-packaged quantities with organized presentation. The 0ATO004.V (bulk format) is appropriate for high-volume procurement or integration into larger component kits. Both parts carry identical safety certifications (CSA, UL) and maintain the same electrical specifications for 4 A, 32 V AC/DC automotive fuse applications.

Frequently Asked Questions (FAQ)

Q: Can the 0ATO004.V be used as a direct replacement for the 0ATO004.VP?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (5-pack card versus bulk). They are interchangeable in any circuit application requiring a 4 A, 32 V AC/DC automotive blade fuse.

Q: What determines compatibility between these fuse models?

A: Compatibility is determined by current rating (4 A), voltage rating (32 V AC/DC), fuse type (automotive), response time (fast blow), and physical package format (Blade, ATO/ATC). All these parameters are identical between the two parts.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The 0ATO004.VP carries SAE approval in addition to CSA and UL certifications, while the 0ATO004.V carries CSA and UL certifications. Both meet automotive safety standards.

Q: What is the physical size of these fuses?

A: Both fuses measure 0.750" L x 0.200" W x 0.480" H (19.05mm x 5.08mm x 12.19mm) and fit standard ATO/ATC blade fuse holders.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (card versus bulk) is a supply and logistics consideration only. It does not affect the electrical characteristics, voltage rating, current rating, or response time of the fuse.
