Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0301020.M is determined by matching the following electrical and mechanical parameters:

• Current Rating: 20 A (exact match required)
• Voltage Rating - AC: 32 V (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Package / Case: 1AG, 1/4" x 5/8" (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitutes maintain these core parameters, ensuring direct compatibility with existing holder assemblies and circuit protection requirements.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 0AGA020.V is a parametric equivalent with active product status. This part maintains all electrical and mechanical specifications of the 0301020.M while offering improved availability. RoHS non-compliance status matches the original part.

Littelfuse 0AGA020.VP is a parametric equivalent supplied in bulk packaging (5-pack card). This part is ROHS3 compliant and REACH unaffected, providing environmental compliance advantages over the original 0301020.M. All electrical and mechanical parameters remain identical.

Eaton BK/AGA-20 is a manufacturer-recommended alternative from a different supplier. This part meets all core electrical and mechanical requirements with documented fast-blow response time and 1kA breaking capacity. UR approval agency certification is provided. DC voltage rating is not specified in available documentation.

For new designs and long-term supply continuity, Littelfuse 0AGA020.VP is preferred due to ROHS3 compliance. For direct replacement in existing systems, Littelfuse 0AGA020.V provides identical specifications with active status. The Eaton BK/AGA-20 serves as a cross-manufacturer alternative when Littelfuse parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can 0AGA020.V directly replace 0301020.M? A: Yes. Both parts share identical electrical ratings (20A, 32VAC/VDC), fuse type (cartridge glass), and mechanical form factor (1AG, 1/4" x 5/8"). No holder modification is required.

Q: What is the difference between 0AGA020.V and 0AGA020.VP? A: Both are parametric equivalents with identical electrical and mechanical specifications. The primary difference is packaging: 0AGA020.V is supplied individually, while 0AGA020.VP is supplied in bulk (5-pack card). Additionally, 0AGA020.VP is ROHS3 compliant, whereas 0AGA020.V is RoHS non-compliant.

Q: Is the Eaton BK/AGA-20 fully compatible? A: The Eaton BK/AGA-20 meets all core substitution parameters: 20A current rating, 32V AC voltage rating, 1AG cartridge glass form factor, and 1/4" x 5/8" dimensions. DC voltage rating is not specified in available data. Verify DC application requirements before selection.

Q: Why is 0301020.M obsolete? A: Product status reflects manufacturer discontinuation. Active alternatives (0AGA020.V, 0AGA020.VP, BK/AGA-20) provide equivalent functionality with improved supply availability.

Q: Which substitute should I choose for new designs? A: For ROHS3 compliance requirements, select Littelfuse 0AGA020.VP. For standard applications without environmental compliance mandates, Littelfuse 0AGA020.V or Eaton BK/AGA-20 are suitable alternatives.

Q: Are all substitutes fast-blow fuses? A: Response time is not specified for Littelfuse parts 0AGA020.V and 0AGA020.VP. The Eaton BK/AGA-20 is documented as fast-blow. Verify response time requirements for your application before final selection.
