Substitute Part Grouping Explanation

Substitution for the 023004.6HXSW is determined by the following critical parameters:

Current Rating: 4.6 A (exact match required)
Voltage Rating - AC: 250 V (exact match required)
Response Time: Slow Blow (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
Size / Dimension: 0.177" Dia x 0.571" L (4.50mm x 14.50mm) (exact match required)
Melting I²t: 110 (exact match required)

All substitute parts listed below meet these criteria. The primary distinction between the obsolete 023004.6HXSW and its substitutes is the addition of DC voltage rating (125 V DC) and enhanced RoHS3 compliance in the active alternatives.

Engineering Selection Recommendations

All substitute parts (023004.6HXSP, 023004.6HXP, 023004.6MXP, 023004.6MXSP, 023004.6VXP) are active products with ROHS3 compliance and expanded regulatory approvals including CE and PSE certifications. These parts are direct functional equivalents to the obsolete 023004.6HXSW, with the addition of specified DC voltage rating (125 V DC) and enhanced breaking capacity for DC applications (10kA DC).

Selection among the active substitutes should be based on packaging requirements and inventory availability. All five substitute parts share identical electrical and mechanical specifications, with differences limited to packaging designation and internal product coding.

Frequently Asked Questions (FAQ)

Q: Can the 023004.6HXSP, 023004.6HXP, 023004.6MXP, 023004.6MXSP, or 023004.6VXP be used as direct replacements for the 023004.6HXSW?

A: Yes. All substitute parts meet the critical electrical and mechanical parameters of the obsolete 023004.6HXSW, including current rating (4.6 A), AC voltage rating (250 V), response time (slow blow), physical dimensions (0.177" Dia x 0.571" L), and melting I²t (110). The substitutes are active products with enhanced compliance status.

Q: What is the difference between the substitute part numbers?

A: The five substitute parts are parametrically equivalent. Differences are limited to internal product coding and packaging designation. All share identical electrical specifications, physical dimensions, and performance characteristics.

Q: Does the addition of DC voltage rating (125 V DC) in the substitutes affect compatibility?

A: No. The addition of DC voltage rating in the substitute parts represents an enhancement that expands application capability. AC-only applications remain fully compatible.

Q: Are the substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, whereas the original 023004.6HXSW is RoHS non-compliant. This represents an improvement in environmental and regulatory compliance.

Q: What regulatory approvals do the substitute parts carry?

A: The substitute parts carry CE, CSA, PSE, and UL approvals, compared to CSA, METI, and UL for the original part. The expanded approval set reflects current regulatory requirements.
