Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH424705D is determined by the following critical parameters:

• Position Count & Pitch: 24 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical and electrical compatibility)
• Connector Type: Plug with female sockets (required for mating interface compatibility)
• Termination Method: Screwless push-in spring termination (ensures compatibility with existing wire preparation and installation procedures)
• Mounting Configuration: Free hanging (in-line) orientation (required for form factor compatibility)
• Electrical Ratings: Minimum 300 V UL voltage rating and support for 12-26 AWG wire gauge (ensures electrical safety and wire compatibility)
• Material Compliance: UL94 V-0 flammability rating and ROHS3 compliance (maintains regulatory and safety standards)

The substitute part HW2470020000G from Amphenol Anytek meets all critical substitution criteria. The primary difference is wire entry orientation (180° versus 270°), which represents a mechanical variation that may require installation procedure adjustment but does not affect electrical compatibility or functional performance.

Parameter Comparison

Engineering Selection Recommendations

The HW2470020000G qualifies as a direct substitute for the obsolete OSTH424705D based on matching electrical specifications, mechanical dimensions, and regulatory compliance. Both components maintain identical position counts, pitch spacing, termination methodology, and voltage ratings. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

The HW2470020000G provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), which represents an operational advantage for applications requiring broader thermal performance. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, satisfying regulatory requirements for equivalent applications.

The wire entry orientation difference (180° on the substitute versus 270° on the original) constitutes a mechanical variation that affects installation geometry but does not impact electrical performance or connector compatibility. System integration must account for this orientation change during physical layout planning.

Frequently Asked Questions (FAQ)

Q: Can HW2470020000G directly replace OSTH424705D without any modifications?

A: The HW2470020000G meets all critical electrical and mechanical compatibility requirements. The primary consideration is wire entry orientation: the substitute features 180° entry versus the original 270°. Physical installation geometry must be evaluated to confirm spatial compatibility within the application enclosure.

Q: Are the electrical ratings identical between these two parts?

A: Both components support 300 V UL voltage rating, 12-26 AWG wire gauge range, and identical termination methodology. The substitute provides a wider operating temperature range (-40°C to 115°C versus -30°C to 105°C), which is operationally equivalent or superior for most applications.

Q: What is the significance of the wire entry orientation difference?

A: Wire entry orientation (180° versus 270°) determines the physical angle at which wires enter the connector. This affects installation routing and enclosure layout but does not alter electrical function, mating compatibility, or signal integrity.

Q: Are both parts RoHS and REACH compliant?

A: Both OSTH424705D and HW2470020000G are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage, handling, or installation.

Q: Are the contact materials and finishes equivalent?

A: Both components utilize phosphor bronze contacts with tin mating finish, ensuring equivalent electrical conductivity and corrosion resistance characteristics.
