BK/AGC-30 Equivalent & Substitute Parts Reference

Part Overview

The BK/AGC-30 is a 30 A, 32 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This component is classified as obsolete, requiring identification of active equivalent alternatives for ongoing system maintenance and new designs. The AGC series fuse operates within a temperature range of -55°C to 125°C and is approved by CSA and UL standards. Due to its obsolete status, direct substitution with active product variants is necessary to ensure supply chain continuity and compliance with current manufacturing standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/AGC-30 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Current Rating: 30 A (exact match required)
• Voltage Rating (AC): 32 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

Secondary Consideration:

• Product Status: Active variants are preferred over obsolete originals to ensure long-term availability

All substitute parts listed below meet these primary criteria. Variations in breaking capacity, melting I²t, DC cold resistance, and RoHS compliance status are noted but do not disqualify substitution when primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: BK/AGC-30-R

The BK/AGC-30-R is the direct active equivalent manufactured by Eaton - Electronics Division. This part maintains identical electrical and mechanical specifications to the obsolete BK/AGC-30 while offering active product status and ROHS3 compliance. Selection of this variant ensures supply chain continuity from the original equipment manufacturer and eliminates cross-manufacturer compatibility concerns.

Secondary Recommendation: AGC-30-R

The AGC-30-R provides equivalent functionality with active status and RoHS compliance. This variant differs only in packaging designation (Bulk vs. standard) and represents an alternative within the Eaton AGC series.

Alternative Recommendation: BK/AGC-30LX-R

The BK/AGC-30LX-R offers identical electrical and mechanical parameters with an elevated breaking capacity of 10kA compared to the 1kA rating of the original BK/AGC-30. This variant is suitable for applications requiring higher fault current protection margins.

Cross-Manufacturer Alternatives: Littelfuse 0312030 Series

The Littelfuse 0312030.HXP, 0312030.MXP, and 0312030.VXP variants meet all primary substitution criteria. These parts feature lower melting I²t values (3717 vs. 4950) and reduced DC cold resistance (0.0019 vs. 0.0024 Ohms), indicating faster response characteristics. All variants carry ROHS3 compliance and active product status. Cross-manufacturer substitution is electrically and mechanically valid when primary parameters align.

Parametric Equivalent: 0311030.H

The Littelfuse 0311030.H meets all primary electrical and mechanical criteria with active status and ROHS3 compliance. Incomplete specification data for breaking capacity and melting I²t does not disqualify this variant for substitution purposes.

Frequently Asked Questions (FAQ)

Q: Can the BK/AGC-30 be directly replaced with AGC-30-R?

A: Yes. Both parts share identical current rating (30 A), voltage rating (32 V AC), fuse type (cartridge glass), response time (fast blow), package designation (3AB, 3AG), and physical dimensions (0.250" x 1.250"). The primary difference is product status and RoHS compliance. AGC-30-R is active and RoHS compliant.

Q: What is the difference between BK/AGC-30-R and BK/AGC-30LX-R?

A: Both parts are electrically and mechanically identical except for breaking capacity. The BK/AGC-30-R has a breaking capacity of 1kA, while the BK/AGC-30LX-R has 10kA. The higher breaking capacity of the LX-R variant provides enhanced protection in circuits with higher available fault currents.

Q: Are Littelfuse 0312030 series fuses compatible with Eaton AGC holders?

A: Yes. The Littelfuse 0312030.HXP, 0312030.MXP, and 0312030.VXP variants share identical package designation (3AB, 3AG) and physical dimensions (0.250" Dia x 1.250" L) with the BK/AGC-30. These parts are mechanically compatible with standard 3AB and 3AG fuse holders.

Q: How do the electrical characteristics of Littelfuse 0312030 parts differ from Eaton AGC parts?

A: Littelfuse 0312030 variants exhibit lower melting I²t (3717 vs. 4950) and reduced DC cold resistance (0.0019 vs. 0.0024 Ohms). These differences indicate faster thermal response. Both manufacturers' parts meet the same current and voltage ratings and are approved by CSA and UL standards.

Q: What does ROHS3 compliance mean for fuse selection?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 3, which restricts the use of specific hazardous materials in electrical and electronic equipment. All active substitute variants listed carry ROHS3 compliance, making them suitable for applications requiring regulatory compliance.

Q: Can 0311030.H be used as a substitute despite incomplete specification data?

A: Yes. The 0311030.H meets all primary substitution criteria: 30 A current rating, 32 V AC voltage rating, fast-blow response, cartridge glass fuse type, 3AB/3AG package, and 0.250" x 1.250" dimensions. Incomplete breaking capacity and melting I²t data does not affect mechanical or primary electrical compatibility.

Q: Is the operating temperature range consistent across all substitute parts?

A: Yes. All substitute parts operate within the -55°C to 125°C temperature range specified for the original BK/AGC-30, ensuring thermal compatibility across the product line.

Q: What approval agencies certify these fuse products?

A: All parts listed carry CSA and UL approvals, with some variants carrying cULus certification. These certifications confirm compliance with North American electrical safety standards.
