Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0ATO005.ZXPRO is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Fuse Type: Automotive (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: Blade, ATO/ATC (exact match required)
• Physical Dimensions: 0.750" L x 0.200" W x 0.480" H (exact match required)
• Series: ATO® (exact match required)

The substitute part 0ATO005.VXPK meets all electrical and mechanical parameters. The primary difference is packaging configuration: 0ATO005.VXPK is supplied as a 5-piece box, whereas 0ATO005.ZXPRO is supplied as a single unit in a box. Both parts are functionally identical for circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The 0ATO005.ZXPRO is the recommended primary selection due to its active product status and higher inventory availability. This part maintains full compliance with CSA, SAE, and UL certifications and is ROHS3 compliant.

The 0ATO005.VXPK is electrically and mechanically equivalent but carries an obsolete product status designation. Selection of this substitute should be limited to applications where 5-piece packaging is specifically required and where the obsolete status does not conflict with procurement or supply chain requirements. Both parts provide identical circuit protection performance within automotive electrical systems rated for 32V AC/DC operation at 5A current levels.

Frequently Asked Questions (FAQ)

Q: Can 0ATO005.VXPK be used as a direct replacement for 0ATO005.ZXPRO?

A: Yes. Both parts are electrically and mechanically identical. They share the same current rating (5A), voltage rating (32V AC/DC), response time (fast blow), physical dimensions, and ATO/ATC blade configuration. The primary difference is packaging: 0ATO005.VXPRO is supplied individually, while 0ATO005.VXPK is supplied as a 5-piece set.

Q: What does the obsolete status of 0ATO005.VXPK mean for component selection?

A: Obsolete status indicates that Littelfuse Inc. has discontinued active production of this part number. While existing inventory remains available, future procurement may become limited. For new designs or long-term supply requirements, 0ATO005.ZXPRO is the preferred choice due to its active status.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts are designed for identical ATO/ATC holder mounting and operate within the same electrical parameters. Physical dimensions are identical, ensuring proper fit within automotive fuse holders.

Q: Does packaging configuration affect electrical performance?

A: No. Packaging configuration (single unit versus 5-piece box) does not affect the electrical or mechanical performance of individual fuses. Selection between these options should be based on application requirements and inventory needs.

Q: Are both parts compliant with automotive standards?

A: Yes. Both 0ATO005.ZXPRO and 0ATO005.VXPK carry identical certifications: CSA, SAE, and UL approval. Both are ROHS3 compliant and suitable for automotive electrical system applications.
