OSTH423705D Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH423705D is a 23-position terminal block plug manufactured by On-Shore Technology, featuring female sockets with 0.197" (5.00mm) pitch spacing and 270° 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 is designed for free-hanging (in-line) mounting applications with screwless push-in spring termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH423705D is determined by strict alignment across the following critical parameters:

• Position Count & Pitch: Substitute must maintain 23 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors
• Connector Type: Must be a plug with female sockets to match the original interface
• Termination Method: Screwless push-in spring termination is required for installation compatibility
• Mounting Configuration: Free-hanging (in-line) mounting type must be preserved
• Electrical Ratings: Voltage rating of 300 V UL and wire gauge range of 12-26 AWG must be maintained or exceeded
• Material Specifications: Phosphor bronze contacts and thermoplastic housing with UL94 V-0 flammability rating ensure safety and performance equivalence
• Regulatory Compliance: RoHS3 compliance is mandatory for modern procurement standards

The HW2370020000G 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 assessment based on specific application geometry.

Parameter Comparison

Engineering Selection Recommendations

The HW2370020000G qualifies as a direct functional substitute for the OSTH423705D based on electrical, mechanical, and regulatory equivalence. Both components maintain identical position counts, pitch spacing, termination methods, and safety certifications (UL94 V-0, RoHS3 compliance).

The HW2370020000G offers operational advantages: active product status ensures long-term availability, an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), and documented current rating of 10 A UL. The substitute is available in bulk packaging with 958 units in stock.

The primary consideration is wire entry orientation: the OSTH423705D features 270° entry while the HW2370020000G provides 180° entry. This difference is mechanical and does not affect electrical performance. Installation feasibility depends on available space and cable routing geometry in the target application. Physical verification of connector orientation compatibility with the mating receptacle and surrounding enclosure is necessary before final selection.

Frequently Asked Questions (FAQ)

Q: Can the HW2370020000G directly replace the OSTH423705D without modification?

A: Electrical and mechanical compatibility is confirmed across all critical parameters. However, the 90° difference in wire entry orientation (270° versus 180°) may require assessment of installation space. If the original 270° orientation is essential to your application geometry, physical fit verification is required before deployment.

Q: Are the electrical ratings equivalent?

A: Yes. Both components support 300 V UL, 12-26 AWG wire gauge, and identical contact materials (phosphor bronze). The HW2370020000G additionally specifies 10 A UL current rating, which is not documented for the OSTH423705D but does not create incompatibility.

Q: What is the significance of the product status difference?

A: The OSTH423705D is obsolete, meaning On-Shore Technology no longer manufactures or supports this part. The HW2370020000G is active, ensuring continued availability, technical support, and compliance with evolving regulatory standards. For new designs or long-term procurement, the active substitute is preferred.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the OSTH423705D and HW2370020000G meet RoHS3 compliance requirements, confirming suitability for applications subject to EU and equivalent regulatory frameworks.

Q: Does the wider operating temperature range of the HW2370020000G (-40°C to 115°C) affect compatibility?

A: No. A wider operating temperature range represents an enhancement, not a limitation. If your application operates within the original OSTH423705D range (-30°C to 105°C), the substitute will perform equivalently or better.

Q: What packaging differences exist between these parts?

A: The OSTH423705D packaging is not specified in available documentation. The HW2370020000G is supplied in bulk packaging with 958 units currently in stock. Confirm packaging requirements with your procurement process.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts carry identical safety certifications (UL94 V-0 flammability rating) and regulatory compliance status (RoHS3, REACH Unaffected, EAR99 ECCN classification). No compliance barriers exist for substitution.
