OSTH424705C Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH424705C is a 24-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 90° wire entry orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The part operates across -30°C to 105°C with 300V UL rating and supports wire gauges from 12-26 AWG using screwless push-in spring termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH424705C is determined by strict alignment across the following critical parameters:

• Position Count & Pitch: Substitute must maintain 24 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors
• Connector Type: Female socket plugs only; male pin configurations are not interchangeable
• Termination Method: Screwless push-in spring termination required for wire insertion compatibility
• Mounting Configuration: Free hanging (in-line) orientation mandatory
• Electrical Ratings: Minimum 300V UL voltage rating and support for 12-26 AWG wire gauge required
• Material Compliance: UL94 V-0 flammability rating and ROHS3 compliance required for regulatory alignment
• Contact Material & Finish: Phosphor bronze with tin mating finish ensures electrical performance consistency

The substitute part HW2470020000G from Amphenol Anytek meets all critical substitution criteria. The primary difference is wire entry orientation (180° vs. 90°), which represents a mechanical variation that does not affect electrical function or connector compatibility when properly integrated into the system design.

Parameter Comparison

Engineering Selection Recommendations

The HW2470020000G qualifies as a direct functional substitute for the obsolete OSTH424705C based on matching electrical specifications, mechanical configuration, and regulatory compliance. Both components maintain identical pitch spacing, position count, termination methodology, and material certifications (UL94 V-0, ROHS3).

The HW2470020000G offers extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and specified current rating (10A UL), providing equivalent or superior performance characteristics. The wire entry orientation difference (180° versus 90°) is a mechanical design consideration that does not affect electrical compatibility with standard mating connectors; system integration must account for this orientation change during physical layout planning.

Active product status of the HW2470020000G ensures ongoing availability and supply chain continuity, eliminating procurement risk associated with the obsolete OSTH424705C.

Frequently Asked Questions (FAQ)

Q: Can HW2470020000G directly replace OSTH424705C without modification?

A: Electrical and connector compatibility is maintained. The 180° wire entry orientation requires physical layout adjustment; the connector itself functions identically with mating components designed for 5.00mm pitch, 24-position female socket plugs.

Q: Are there differences in wire termination between these parts?

A: Both components use identical screwless push-in spring termination. Wire gauge acceptance (12-26 AWG) and insertion methodology are equivalent.

Q: What is the significance of the operating temperature range difference?

A: The HW2470020000G supports -40°C to 115°C versus -30°C to 105°C for the OSTH424705C. If your application operates within the original -30°C to 105°C window, both parts are suitable. Applications requiring extended low-temperature operation benefit from the HW2470020000G specification.

Q: Does the HW2470020000G meet the same regulatory requirements?

A: Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification. Regulatory compliance is equivalent.

Q: Is the 10A current rating of HW2470020000G a limiting factor?

A: The OSTH424705C does not specify a UL current rating. The HW2470020000G 10A specification represents a defined electrical limit suitable for standard terminal block applications. System design must confirm current requirements do not exceed this rating.

Q: What packaging differences exist?

A: OSTH424705C is listed as obsolete with no active packaging designation. HW2470020000G is supplied in bulk packaging and maintains active production status.
