AGC-12-R Equivalent & Substitute Parts

Part Overview

The AGC-12-R is a 12 A, 32 V AC/DC fast-blow glass fuse cartridge manufactured by Eaton - Electronics Division. This component operates within the temperature range of -55°C to 125°C and is housed in a 3AB/3AG package format measuring 0.250" diameter by 1.250" length. The part requires a compatible fuse holder for installation and is currently active in production status. Substitute parts are necessary when primary inventory is unavailable, when alternative manufacturer certifications are required, or when specific performance characteristics of equivalent designs are preferred for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AGC-12-R is determined by strict equivalence across the following critical parameters: current rating (12 A), voltage rating (32 V AC), fuse type (cartridge glass), response time (fast blow), and physical package dimensions (3AB/3AG, 0.250" x 1.250"). All substitute parts listed maintain identical electrical and mechanical specifications to ensure direct interchangeability within existing fuse holder assemblies.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Manufacturer): BK/AGC-12-R from Eaton - Electronics Division maintains identical specifications and certifications.

Functional Equivalents (Alternative Manufacturers): Parts 0312012.HXP, 0312012.MXP, and 0312012.VXP from Littelfuse Inc. meet all electrical and mechanical requirements while offering alternative sourcing and certification pathways.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: BK/AGC-12-R from Eaton - Electronics Division is the direct equivalent with identical manufacturer origin, certification pathway (CSA, UL), and electrical characteristics. This part is recommended when maintaining single-source supplier consistency is a design requirement.

Alternative Selection: The Littelfuse 312 series parts (0312012.HXP, 0312012.MXP, 0312012.VXP) are functionally equivalent alternatives that satisfy all electrical and mechanical requirements. These parts carry active product status and maintain full compliance with CSA and UL certifications. Selection among the three Littelfuse variants depends on internal manufacturing designations (HXP, MXP, VXP) which do not affect electrical performance or mechanical compatibility.

All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The minor variation in DC cold resistance (0.006 Ohms for Eaton versus 0.0072 Ohms for Littelfuse) remains within acceptable operational parameters for this fuse category and does not impact circuit protection performance.

Frequently Asked Questions (FAQ)

Q: Can AGC-12-R be directly replaced with BK/AGC-12-R?

A: Yes. BK/AGC-12-R is a direct equivalent from the same manufacturer with identical electrical ratings (12 A, 32 V), fuse type (cartridge glass), response time (fast blow), physical dimensions (0.250" x 1.250"), and operating temperature range (-55°C to 125°C). Both parts require the same 3AB/3AG fuse holder.

Q: Are Littelfuse 312 series fuses compatible with AGC-12-R applications?

A: Yes. Parts 0312012.HXP, 0312012.MXP, and 0312012.VXP from Littelfuse meet all critical electrical and mechanical specifications: 12 A current rating, 32 V voltage rating, fast-blow response, identical physical dimensions, and compatible 3AB/3AG package format. These parts are interchangeable within the same fuse holder assembly.

Q: What is the difference between 0312012.HXP, 0312012.MXP, and 0312012.VXP?

A: These three Littelfuse parts are electrically and mechanically identical. The letter designations (HXP, MXP, VXP) represent internal manufacturing or distribution variants and do not affect performance, compatibility, or electrical characteristics. Selection among these variants is based on supplier availability and internal sourcing preferences.

Q: Do all substitute parts carry the same certifications as AGC-12-R?

A: BK/AGC-12-R carries identical certifications (CSA, UL). Littelfuse parts 0312012.HXP and 0312012.MXP carry CSA and cULus certifications, while 0312012.VXP carries CSA and UL certifications. All certifications meet industry standards for this fuse category.

Q: Can these fuses be used in circuits rated for different voltages?

A: No. All listed parts are rated for 32 V AC operation. Use only in circuits matching this voltage specification. Exceeding the rated voltage will compromise fuse performance and circuit protection.

Q: What is the significance of the 3AB/3AG package designation?

A: The 3AB/3AG designation specifies the physical form factor and holder compatibility. All listed substitute parts conform to this standard, ensuring mechanical fit within existing 3AB/3AG fuse holder assemblies. The dimensions 0.250" diameter by 1.250" length are consistent across all equivalent parts.

Q: Are there any temperature limitations when selecting a substitute?

A: All listed parts operate within the identical temperature range of -55°C to 125°C. Temperature performance is equivalent across all substitute options.
