BP/ATC-5 Equivalent & Substitute Parts Reference

Part Overview

The BP/ATC-5 is a 5A automotive blade fuse rated for 32V DC operation, manufactured by Eaton - Bussmann Electrical Division under the ATC® series designation. This component is classified as obsolete, requiring identification of active equivalent alternatives for continued system support and procurement. Substitute parts must maintain identical electrical ratings, mechanical form factor, and approval certifications to ensure direct interchangeability in automotive fuse holder applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (5A), DC voltage rating (32V), fuse type (automotive), package form factor (Blade, ATO/ATC), response time (fast blow), and breaking capacity (1kA). All substitute parts listed maintain these core electrical and mechanical specifications.

Eaton - Bussmann Electrical Division substitutes (ATC-5 and BK/ATC-5) are parametric equivalents with identical dimensional and electrical characteristics, differing only in packaging configuration and product status. Both are active alternatives to the obsolete BP/ATC-5.

Littelfuse Inc. direct manufacturer substitutes (0287005.H, 0287005.PXCN, 0ATO005.V, 0ATO005.VP, 0ATO005.ZXPRO) meet all core electrical parameters and are classified as direct or similar equivalents. Dimensional tolerances remain within acceptable limits for standard ATO/ATC holder compatibility. The 0ATO005 series variants differ in packaging configuration (bulk, card, box) but maintain identical electrical performance.

Engineering Selection Recommendations

For direct replacement of the obsolete BP/ATC-5, the active Eaton - Bussmann ATC-5 or BK/ATC-5 are the primary selections, maintaining identical electrical specifications, dimensional tolerances, and UL certification. Both parts are in active production with established supply chains.

Littelfuse 0287005.H and 0287005.PXCN are qualified direct manufacturer alternatives meeting all core electrical and mechanical parameters with UL approval. These parts are suitable where multi-source qualification is required.

Littelfuse 0ATO005 series variants (0ATO005.V, 0ATO005.VP, 0ATO005.ZXPRO, 0ATO005.HXGLO, 0ATO005.MXGLO, 0ATO005.VPGLO) are functionally equivalent with identical current and voltage ratings. Selection among these variants depends on packaging requirements: bulk, card, or box configurations. All carry CSA and UL certifications, with some variants including SAE approval.

Component selection should prioritize active product status and established inventory availability. RoHS3 compliance is confirmed across all active substitute options.

Frequently Asked Questions (FAQ)

Q: Can the obsolete BP/ATC-5 be directly replaced with ATC-5 or BK/ATC-5?

A: Yes. Both ATC-5 and BK/ATC-5 are parametric equivalents with identical 5A current rating, 32V DC voltage rating, fast blow response, 1kA breaking capacity, and ATO/ATC blade form factor. Both are UL approved and in active production.

Q: What is the difference between Eaton - Bussmann and Littelfuse substitutes?

A: Both manufacturers produce fuses meeting the same electrical specifications (5A, 32V DC, fast blow, ATO/ATC package). Littelfuse variants may differ in packaging configuration (bulk, card, box) and include additional certifications (CSA, SAE). All are functionally interchangeable in standard automotive fuse holder applications.

Q: Are the Littelfuse 0ATO005 series variants interchangeable?

A: Yes, all 0ATO005 variants (0ATO005.V, 0ATO005.VP, 0ATO005.ZXPRO, 0ATO005.HXGLO, 0ATO005.MXGLO, 0ATO005.VPGLO) maintain identical electrical performance. Differences are limited to packaging format: individual bulk units, card packs (2-pack or 5-pack), or box configurations. Selection depends on procurement and inventory requirements.

Q: Do all substitutes fit standard ATO/ATC fuse holders?

A: Yes. All listed substitutes use the Blade, ATO/ATC form factor and are designed for standard automotive fuse holder compatibility. Dimensional variations are within acceptable tolerances for reliable holder engagement.

Q: What compliance certifications apply to these substitutes?

A: The original BP/ATC-5 carries UL approval. All active substitutes maintain UL certification. Littelfuse variants additionally carry CSA approval, with some including SAE certification. All active parts are RoHS3 compliant and REACH unaffected.

Q: Which substitute offers the highest inventory availability?

A: Littelfuse 0287005.PXCN shows the highest inventory level at 290,794 pieces in stock, followed by BK/ATC-5 at 2,821 pieces. Both are suitable for high-volume procurement requirements.
