Littelfuse 0301003.M Glass Cartridge Fuse 3A 32V Equivalent & Substitute Parts

Part Overview

The Littelfuse 0301003.M is a 3 A, 32 V AC/DC glass cartridge fuse in the 1AG form factor (1/4" x 5/8"). This component is designed for circuit protection in applications requiring reliable overcurrent interruption at low voltage levels. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0301003.M are qualified based on the following critical parameters that determine functional interchangeability:

• Current Rating: 3 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 1AG, 1/4" x 5/8" (exact match required)
• Physical Dimensions: 0.250" Dia x 0.625" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

The identified substitutes (0AGA003.V and 0AGA003.VP) meet all these criteria. The primary difference between substitute parts is packaging configuration: 0AGA003.V is supplied in bulk, while 0AGA003.VP is supplied in a 5-pack card format. Both variants are electrically and mechanically identical to the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts (0301003.M, 0AGA003.V, and 0AGA003.VP) are Active status components manufactured by Littelfuse Inc. and carry identical ROHS3 and REACH compliance certifications. Selection between these parts should be based on packaging requirements and inventory availability:

• 0301003.M: Bulk packaging, 833 units in stock
• 0AGA003.V: Bulk packaging, 812 units in stock
• 0AGA003.VP: 5-pack card format, 844 units in stock

The choice between bulk and card packaging depends on application assembly requirements and procurement workflows. All three parts are electrically and mechanically interchangeable for circuits requiring 3 A protection at 32 V AC/DC with 1AG form factor fuses.

Frequently Asked Questions (FAQ)

Q: Can 0AGA003.V and 0AGA003.VP be used interchangeably with 0301003.M?

A: Yes. All three parts are electrically and mechanically identical. They share the same current rating (3 A), voltage rating (32 V AC/DC), fuse type (cartridge, glass), package designation (1AG), and physical dimensions (0.250" Dia x 0.625" L). The only difference is packaging format: bulk versus 5-pack card.

Q: What is the difference between 0AGA003.V and 0AGA003.VP?

A: Both parts are electrically and mechanically identical. The difference is packaging: 0AGA003.V is supplied in bulk format, while 0AGA003.VP is supplied in a 5-pack card format. Selection depends on procurement and assembly requirements.

Q: Are these fuses suitable for both AC and DC applications?

A: Yes. All three parts are rated for 32 V AC and 32 V DC operation. They are suitable for circuits operating at either voltage type within the specified rating.

Q: What holder type is required for these fuses?

A: These are 1AG form factor cartridge fuses that require a compatible 1AG fuse holder. The holder must accommodate the 1/4" diameter x 5/8" length dimensions.

Q: Are all three parts ROHS3 compliant?

A: Yes. 0301003.M, 0AGA003.V, and 0AGA003.VP are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
