Littelfuse 0ATO07.5V Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0ATO07.5V is a 7.5 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 ATO/ATC format. The part maintains active product status with full compliance to RoHS3 and REACH standards. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the ATO® series, ensuring direct interchangeability in automotive applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0ATO07.5V is determined by strict equivalence across the following parameters:

• Current Rating: 7.5 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: Blade, ATO/ATC (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Physical Dimensions: 0.750" L x 0.200" W x 0.480" H (exact match required)
• Series: ATO® (exact match required)

All four substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the 0ATO07.5V.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full compliance with RoHS3 and REACH standards. Selection between 0ATO07.5V and its substitutes should be based on:

• Approval agency requirements: 0ATO07.5HXGLO, 0ATO07.5MXGLO, and 0ATO07.5VP include SAE certification in addition to CSA and UL, providing broader automotive standards coverage.
• Packaging configuration: 0ATO07.5VP is supplied in 5-pack card format, while 0ATO07.5V, 0ATO07.5HXGLO, 0ATO07.5MXGLO, and 0ATO07.5VPGLO are supplied in bulk.
• Inventory availability: 0ATO07.5MXGLO offers the highest stock level at 1691 pieces, followed by 0ATO07.5HXGLO at 1237 pieces.

Frequently Asked Questions (FAQ)

Q: Can 0ATO07.5HXGLO, 0ATO07.5MXGLO, 0ATO07.5VP, and 0ATO07.5VPGLO be used interchangeably with 0ATO07.5V?

A: Yes. All substitute parts share identical electrical ratings (7.5 A, 32 V AC/DC, fast-blow response), mechanical dimensions (0.750" L x 0.200" W x 0.480" H), and ATO/ATC blade package format. Direct substitution is electrically and mechanically valid.

Q: What is the difference between bulk and 5-pack card packaging?

A: 0ATO07.5VP is supplied in 5-pack card format for retail or small-quantity applications. 0ATO07.5V, 0ATO07.5HXGLO, 0ATO07.5MXGLO, and 0ATO07.5VPGLO are supplied in bulk packaging for high-volume procurement. Electrical and mechanical specifications are identical.

Q: Does SAE certification on substitute parts affect compatibility?

A: No. SAE certification on 0ATO07.5HXGLO, 0ATO07.5MXGLO, and 0ATO07.5VP represents additional approval coverage beyond the CSA and UL certifications on 0ATO07.5V and 0ATO07.5VPGLO. All parts meet the same electrical and mechanical requirements for automotive blade fuse applications.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. All listed parts, including 0ATO07.5V and its substitutes, are ROHS3 Compliant and REACH Unaffected.

Q: Can these fuses be used in non-automotive applications?

A: These are automotive-rated fuses designed for automotive electrical circuits. Application suitability must be determined by the specific circuit requirements and voltage/current parameters of the intended use.
