Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ABC-V-4-R are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Mandatory Matching Parameters:

• Current Rating: 4 A (exact match)
• Voltage Rating AC: 250 V (exact match)
• Voltage Rating DC: 125 V (exact match)
• Fuse Type: Cartridge, Ceramic (exact match)
• Response Time: Fast Blow (exact match)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match)
• Mounting Type: Through Hole (exact match)

Acceptable Variation Parameters:

• Breaking Capacity: May vary within safe operating limits
• Melting I²t: May vary within acceptable thermal characteristics
• DC Cold Resistance: Minor variations acceptable
• Operating Temperature Range: Extended ranges acceptable
• Approval Agencies: Additional certifications acceptable
• Dimensions: Minor tolerances within package specification acceptable

The substitute part 0324004.HXP from Littelfuse Inc. meets all mandatory matching criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

ABC-V-4-R (Eaton - Electronics Division):

• Primary selection for existing designs and established supply chains
• Active product status with 1100 units in stock
• CSA and UL certifications meet standard regulatory requirements
• ROHS3 compliant for environmental standards

0324004.HXP (Littelfuse Inc.):

• Direct equivalent substitute with identical electrical and mechanical specifications
• Active product status with 1051 units in stock
• Extended certification portfolio including CE, CSA, K-MARK, PSE, and UL
• Specified operating temperature range of -55°C to 125°C
• Higher breaking capacity (750A AC) provides additional safety margin
• ROHS3 compliant with REACH unaffected status
• Suitable for applications requiring broader international compliance or extended temperature operation

Both parts are functionally interchangeable in circuits designed for 4 A, 250 V AC / 125 V DC fast-blow ceramic cartridge fuse protection. Selection between them depends on supply availability, certification requirements, and design specifications.

Frequently Asked Questions (FAQ)

Q: Can 0324004.HXP be used as a direct replacement for ABC-V-4-R?

A: Yes. Both parts share identical current rating (4 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package format (3AB/3AG), and mounting type (through hole). Dimensional tolerances are within acceptable limits for the 1/4" x 1-1/4" package specification.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Breaking capacity at rated voltage is higher for 0324004.HXP (750A AC vs. 200A AC); (2) Melting I²t is lower for 0324004.HXP (10.4 vs. 22.28); (3) DC cold resistance is slightly higher for 0324004.HXP (0.047 vs. 0.031 Ohms); (4) 0324004.HXP specifies operating temperature range (-55°C to 125°C) while ABC-V-4-R does not; (5) 0324004.HXP carries additional international certifications (CE, K-MARK, PSE).

Q: Are there any compatibility concerns with PCB mounting or circuit design?

A: No. Both parts use identical through-hole mounting for 3AB/3AG cartridge fuse holders. Dimensional variations (0.266" vs. 0.275" diameter; 1.292" vs. 1.288" length) fall within standard package tolerances and do not affect mechanical fit or electrical performance in standard fuse holders.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain strategy and regulatory requirements. For applications requiring extended international compliance (CE, K-MARK, PSE), select 0324004.HXP. For standard North American applications, either part is acceptable based on availability and cost considerations.

Q: Do both parts meet RoHS requirements?

A: Yes. Both ABC-V-4-R and 0324004.HXP are ROHS3 compliant. Additionally, 0324004.HXP is REACH unaffected.

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

A: Melting I²t (22.28 for ABC-V-4-R vs. 10.4 for 0324004.HXP) indicates thermal energy required to melt the fuse element. The lower value for 0324004.HXP indicates faster thermal response under fault conditions, which is acceptable for fast-blow fuse applications and provides additional protection margin.
