Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3ABP 15-R are qualified based on the following electrical and mechanical parameters:

• Current Rating: 15 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these core electrical and mechanical criteria. Additional parameters such as DC voltage rating, breaking capacity specifications, and resistance values may vary within acceptable engineering tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are manufactured by Littelfuse Inc. and carry active product status, ensuring long-term availability and supply chain continuity. The substitute parts meet or exceed the core electrical specifications of the 3ABP 15-R.

Selection among substitute options should be based on:

• Approval agency requirements for your application (UL, CSA, CE, PSE, K-MARK, KC certifications)
• DC voltage rating requirements (0324015.HXP, 0324015.MXP, and 0324015.VXP include 125 V DC rating; 0324015.MXSPP does not specify DC rating)
• Inventory availability and packaging requirements (Bulk vs. standard packaging)

All substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original component.

Frequently Asked Questions (FAQ)

Q: Can I use 0324015.HXP, 0324015.MXP, 0324015.MXSPP, or 0324015.VXP as direct replacements for 3ABP 15-R?

A: Yes. All substitute parts share identical current rating (15 A), AC voltage rating (250 V), fuse type (ceramic cartridge), package form factor (3AB/3AG, 1/4" x 1-1/4"), response time (fast blow), and operating temperature range (-55°C ~ 125°C). Physical dimensions are within acceptable tolerance for through-hole mounting.

Q: What is the difference between the substitute parts?

A: The primary differences are: (1) DC voltage rating—0324015.HXP, 0324015.MXP, and 0324015.VXP are rated for 125 V DC, while 0324015.MXSPP does not specify a DC rating; (2) approval agencies—each part carries different certification marks (UL, CSA, CE, PSE, K-MARK, KC); (3) melting I²t and DC cold resistance values differ slightly across all parts.

Q: Does the difference in melting I²t (845 for 3ABP 15-R vs. 292 for Littelfuse substitutes) affect compatibility?

A: Melting I²t is a thermal characteristic that determines fuse response time under specific fault conditions. The substitute parts are qualified as fast-blow ceramic fuses with the same current and voltage ratings. Differences in I²t values reflect manufacturing process variations between manufacturers but do not prevent functional substitution within the specified electrical parameters.

Q: Which substitute should I choose if my application requires DC voltage protection?

A: If your circuit operates at DC voltages up to 125 V, select 0324015.HXP, 0324015.MXP, or 0324015.VXP. If your application is AC-only or does not require DC rating specification, 0324015.MXSPP is also suitable.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 3ABP 15-R.

Q: What certifications should I verify for my specific application?

A: Review the approval agency list for each substitute part against your application requirements. Common certifications include UL (North America), CSA (Canada), CE (Europe), PSE (Japan), K-MARK (Korea), and KC (Korea). The substitute parts collectively cover these major regulatory regions.
