Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AGC-V-4-R are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters:

• Current Rating: 4 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Dimensional Tolerance:

• Physical dimensions must accommodate standard 3AB/3AG cartridge fuse holders with minimal variation

The substitute part 0318004.HXP manufactured by Littelfuse Inc. meets all mandatory electrical and mechanical parameters for direct substitution with the AGC-V-4-R.

Parameter Comparison

Engineering Selection Recommendations

Both the AGC-V-4-R and 0318004.HXP are active products with full regulatory compliance. Selection between these parts should be based on the following factors:

AGC-V-4-R (Eaton):

• Approved by CSA and UL
• RoHS Compliant
• Current inventory: 687 units
• Melting I²t: 86.56

0318004.HXP (Littelfuse):

• Approved by CE, CSA, KC, PSE, and UL (broader international compliance)
• ROHS3 Compliant
• Current inventory: 1,212 units
• Melting I²t: 28.5

Both parts satisfy the core electrical and mechanical requirements for 4 A, 250 V AC/DC fast-blow cartridge fuse applications. The Littelfuse part offers expanded regulatory approvals and higher inventory availability. Dimensional variations (0.009" diameter difference, 0.004" length difference) fall within standard tolerance ranges for 3AB/3AG cartridge fuse holders.

Frequently Asked Questions (FAQ)

Q: Can the 0318004.HXP directly replace the AGC-V-4-R in existing designs?

A: Yes. Both parts share identical electrical ratings (4 A, 250 V AC/DC), response time (Fast Blow), breaking capacity (200 A), and package designation (3AB, 3AG, 1/4" x 1-1/4" Axial). Physical dimensions are within standard tolerance ranges for through-hole cartridge fuse holders.

Q: What is the significance of the different Melting I²t values?

A: The Melting I²t parameter (86.56 for AGC-V-4-R and 28.5 for 0318004.HXP) reflects internal fuse element design differences. Both values are provided in the specifications; however, both parts meet the same 4 A current rating and Fast Blow response time classification.

Q: Are there any compliance differences between these parts?

A: The AGC-V-4-R carries CSA and UL approvals. The 0318004.HXP carries CE, CSA, KC, PSE, and UL approvals. Both are RoHS compliant (AGC-V-4-R is RoHS Compliant; 0318004.HXP is ROHS3 Compliant). The Littelfuse part provides broader international regulatory coverage.

Q: Do the dimensional differences affect mechanical fit?

A: The AGC-V-4-R measures 0.266" Dia x 1.292" L; the 0318004.HXP measures 0.275" Dia x 1.288" L. These variations (0.009" diameter, 0.004" length) are within standard tolerance ranges for 3AB/3AG cartridge fuse holders and do not affect mechanical compatibility.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain requirements, regulatory jurisdiction, and inventory availability. Both parts are active products with identical electrical performance characteristics for 4 A, 250 V AC/DC fast-blow applications.
