Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0318008.HXP are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Current Rating: 8 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Response Time: Fast Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package Configuration: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 200 A (exact match required)
• Melting I²t: 166 (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• DC Cold Resistance: 0.0122 Ohms (exact match required)
• Regulatory Compliance: CE, CSA, KC, PSE, UL (all certifications required)

The substitute part 0318008.MXP meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can 0318008.MXP be used as a direct replacement for 0318008.HXP?

A: Yes. Both parts are parametric equivalents with identical current rating (8 A), voltage rating (250 V AC), response time (Fast Blow), package configuration (3AB, 3AG, 1/4" x 1-1/4"), and all regulatory certifications (CE, CSA, KC, PSE, UL).

Q: Are there any differences in mechanical compatibility?

A: No. Both parts share identical dimensions (0.275" Dia x 1.288" L / 6.99mm x 32.72mm) and mounting type (Through Hole), ensuring identical mechanical fit in 3AB and 3AG fuse holders.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both 0318008.HXP and 0318008.MXP carry identical approval agencies: CE, CSA, KC, PSE, and UL. Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the HXP and MXP packaging designations?

A: The HXP and MXP designations indicate different packaging formats (Bulk for both), but the electrical and mechanical specifications remain identical. Selection depends on procurement and inventory management requirements.

Q: Can these fuses be used in both AC and DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation and are suitable for AC and DC circuit protection applications within the specified voltage and current parameters.
