Engineering Selection Recommendations

All listed substitute parts maintain identical electrical and mechanical specifications to the 0230.600HXSW. The primary distinctions are:

Product Status: The original 0230.600HXSW is obsolete. All substitute parts (0230.600HXSP, 0230.600HXP, 0230.600MXP, 0230.600MXSP, 0230.600VXP, 0230.600VXSP) are active products with current manufacturing support.

Regulatory Compliance: The 0230.600HXSW is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental regulations. Substitute parts additionally carry CE certification in addition to CSA and UL approvals held by the original part.

DC Voltage Rating: The 0230.600HXSW specifies AC voltage only (250 V AC). All substitute parts extend DC voltage capability to 125 V DC with breaking capacity of 10 kA DC, providing enhanced circuit protection in mixed AC/DC applications.

Packaging: The 0230.600HXSW is supplied in standard packaging. Substitute parts are available in bulk packaging format.

Inventory Availability: Substitute parts demonstrate consistent stock levels ranging from 841 to 1780 pieces, ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the 0230.600HXSP, 0230.600HXP, 0230.600MXP, 0230.600MXSP, 0230.600VXP, or 0230.600VXSP be used as direct replacements for the 0230.600HXSW?

A: Yes. All substitute parts maintain identical current rating (600 mA), AC voltage rating (250 V), fuse type (cartridge, glass), response time (slow blow), package configuration (cartridge, non-standard axial), physical dimensions (0.177" Dia x 0.571" L), and operating temperature range (-55°C ~ 125°C). Mechanical and electrical compatibility is assured.

Q: What is the significance of the DC voltage rating on substitute parts?

A: The 0230.600HXSW is rated for AC voltage only. Substitute parts add 125 V DC rating with 10 kA DC breaking capacity. This enhancement allows use in circuits with DC components without compromising protection. In AC-only applications, this additional rating does not affect performance.

Q: Are there differences in thermal or electrical performance between substitute parts?

A: No. All substitute parts share identical melting I²t values (1.75) and DC cold resistance specifications (0.4805 Ohms), ensuring equivalent thermal and electrical response characteristics.

Q: Why do substitute parts carry additional certifications?

A: Substitute parts include CE certification alongside existing CSA and UL approvals. This reflects current regulatory requirements for component distribution in European markets and represents updated compliance standards.

Q: Does RoHS3 compliance affect circuit performance?

A: No. RoHS3 compliance indicates conformance to hazardous substance restrictions in manufacturing. Electrical and mechanical performance remains unchanged. RoHS3 compliance is required for new component procurement in regulated industries.

Q: Are all substitute parts interchangeable in terms of packaging?

A: All substitute parts are supplied in bulk packaging. The 0230.600HXSW was supplied in standard packaging. Bulk packaging does not affect component performance or mechanical fit; it reflects supply format only.
