Key Parameters

Substitute Part Grouping Explanation

The Littelfuse 0318006.HXP qualifies as a parametric equivalent to the 0318006.VXP based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Current Rating: 6 A (identical)
• Voltage Rating (AC): 250 V (identical)
• Response Time: Fast Blow (identical)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (identical)
• Fuse Type: Cartridge, Glass (identical)
• Mounting Type: Through Hole (identical)
• Breaking Capacity @ Rated Voltage: 200 A (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• DC Cold Resistance: 0.0178 Ohms (identical)
• Melting I²t: 118 (identical)
• Approval Agencies: CE, CSA, KC, PSE, UL (identical)
• RoHS Status: ROHS3 Compliant (identical)

Both parts belong to the Littelfuse 318 series and maintain Active product status with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the 0318006.VXP and 0318006.HXP are Active products with identical electrical performance, mechanical dimensions, and regulatory certifications. Selection between these parts is based on availability and procurement requirements. The 0318006.HXP currently maintains higher inventory availability (1235 Pcs) compared to the 0318006.VXP (786 Pcs). Both parts satisfy CE, CSA, KC, PSE, and UL compliance requirements and are ROHS3 compliant. No technical differentiation exists between these components for circuit protection applications requiring 6 A, 250 V AC/DC fast-blow fuse protection in 3AB/3AG package configurations.

Frequently Asked Questions (FAQ)

Q: Can the 0318006.HXP be used as a direct replacement for the 0318006.VXP?

A: Yes. Both parts are parametric equivalents with identical current rating, voltage rating, response time, package configuration, breaking capacity, and operating temperature range. No circuit modifications or design changes are required.

Q: Are there any differences in regulatory compliance between these parts?

A: No. Both parts carry identical approval certifications: CE, CSA, KC, PSE, and UL. Both are ROHS3 compliant and REACH unaffected.

Q: Do these fuses have the same physical dimensions?

A: Yes. Both parts use the 3AB and 3AG package configuration with dimensions of 0.275" diameter × 1.288" length (6.99mm × 32.72mm). They are mechanically interchangeable in through-hole mounting applications.

Q: What is the difference between the part numbers 0318006.VXP and 0318006.HXP?

A: The part numbers differ only in their suffix designation (.VXP versus .HXP). All electrical, mechanical, and performance specifications are identical. The suffix typically indicates internal manufacturing or packaging variations that do not affect functional performance.

Q: Are the DC cold resistance values the same?

A: Yes. Both parts have a DC cold resistance of 0.0178 Ohms and identical melting I²t values of 118.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times, as both parts are functionally equivalent and maintain Active product status.
