Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0ATO001.VP are identified based on strict equivalence of the following critical parameters:

• Current Rating: 1 A
• Voltage Rating: 32 V AC and 32 V DC
• Fuse Type: Automotive
• Response Time: Fast Blow
• Package / Case: Blade, ATO/ATC
• Physical Dimensions: 0.750" L x 0.200" W x 0.480" H
• Series: ATO®

The substitute part 0ATO001.V maintains all electrical and mechanical specifications identical to the main part. Both parts are manufactured by Littelfuse Inc. and comply with RoHS3 and REACH requirements. Substitution is valid when the application requires an ATO/ATC blade fuse with 1 A current protection at 32 V AC/DC operation.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ATO001.VP and 0ATO001.V are active products from Littelfuse Inc. with full compliance to RoHS3 and REACH regulations. The 0ATO001.VP is supplied in 5-pack card packaging, while the 0ATO001.V is supplied in bulk packaging. Selection between these parts depends on packaging requirements and inventory availability. The 0ATO001.V currently has higher inventory availability (1717 units) compared to the 0ATO001.VP (855 units). Both parts carry UL and CSA approvals, with the 0ATO001.VP additionally certified by SAE. For applications requiring ATO/ATC blade fuse protection at 1 A and 32 V AC/DC, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 0ATO001.V be used as a direct replacement for the 0ATO001.VP?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current ratings (1 A), voltage ratings (32 V AC/DC), response time (fast blow), package type (blade, ATO/ATC), and physical dimensions. The primary difference is packaging format: the 0ATO001.VP is supplied in 5-pack card packaging, while the 0ATO001.V is supplied in bulk.

Q: What are the critical parameters that determine fuse substitution?

A: For automotive blade fuses in the ATO/ATC series, substitution is valid when the following parameters match: current rating (1 A), voltage rating (32 V AC and 32 V DC), fuse type (automotive), response time (fast blow), and physical dimensions (0.750" L x 0.200" W x 0.480" H).

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS3 compliant and REACH unaffected. The 0ATO001.VP carries CSA, SAE, and UL approvals, while the 0ATO001.V carries UL approval. For applications requiring SAE certification, the 0ATO001.VP is the specified part.

Q: What is the difference between the packaging options?

A: The 0ATO001.VP is supplied in 5-pack card packaging, suitable for smaller quantity orders or retail distribution. The 0ATO001.V is supplied in bulk packaging, suitable for high-volume manufacturing or OEM applications.

Q: Can these fuses be used in any ATO/ATC holder?

A: Yes. Both parts are designed for standard ATO/ATC blade fuse holders. The physical dimensions (0.750" L x 0.200" W x 0.480" H) conform to the ATO/ATC standard, ensuring compatibility with any compliant holder.
