OSTH407705C Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH407705C is a 7-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 maintenance and new design implementations. The part supports wire gauges from 12-26 AWG with push-in spring termination and operates across a temperature range of -30°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH407705C is determined by strict alignment across the following critical parameters:

• Position Count & Pitch: Substitute must provide exactly 7 positions at 0.197" (5.00mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors
• Connector Type: Substitute must be a plug with female sockets to maintain proper mating interface
• Termination Method: Substitute must employ screwless push-in spring termination for equivalent installation procedures
• Mounting Configuration: Substitute must support free-hanging in-line mounting orientation
• Electrical Ratings: Substitute must meet or exceed 300 V UL voltage rating and support 12-26 AWG wire gauge range
• Material Compliance: Substitute must maintain UL94 V-0 flammability rating and ROHS3 compliance status
• Contact Materials: Substitute must use phosphor bronze contacts with tin mating finish for equivalent electrical performance

The HW0770020000G from Amphenol Anytek satisfies all mandatory substitution criteria, with the primary distinction being wire entry orientation (180° versus 90°), which represents a mechanical configuration difference rather than an electrical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The HW0770020000G qualifies as a direct functional substitute for the OSTH407705C based on electrical and mechanical parameter alignment. Both components maintain identical position counts, pitch spacing, termination methodology, and compliance certifications (ROHS3, UL94 V-0). The HW0770020000G offers the additional advantage of active product status, ensuring continued availability and supply chain reliability compared to the obsolete OSTH407705C.

The primary design consideration is wire entry orientation: the OSTH407705C features 90° entry while the HW0770020000G provides 180° entry. This difference affects physical installation geometry and must be evaluated within the context of the specific application's spatial constraints and wiring layout requirements. The HW0770020000G also provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), which may offer improved performance in temperature-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the HW0770020000G directly replace the OSTH407705C without modification?

A: The HW0770020000G is electrically and mechanically compatible with the OSTH407705C. The primary difference is wire entry orientation (180° versus 90°). Physical installation geometry must be verified to confirm spatial compatibility within the target application.

Q: What does the difference in wire entry orientation mean for installation?

A: Wire entry orientation specifies the angle at which wires enter the terminal block connector. The 90° orientation of the OSTH407705C directs wires perpendicular to the connector body, while the 180° orientation of the HW0770020000G directs wires in the opposite direction. Installation feasibility depends on available space and wiring routing in the specific application.

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

A: Both components support 300 V UL voltage rating, 12-26 AWG wire gauge range, and identical contact materials (phosphor bronze with tin finish). Electrical performance is equivalent for standard applications within these specifications.

Q: Does the extended temperature range of the HW0770020000G affect compatibility?

A: The HW0770020000G operates from -40°C to 115°C compared to the OSTH407705C range of -30°C to 105°C. This represents an expanded operating envelope and does not create incompatibility. Applications requiring operation within the original temperature range remain fully supported.

Q: Are both parts RoHS and REACH compliant?

A: Both the OSTH407705C and HW0770020000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the OSTH407705C listed as obsolete?

A: Obsolete status indicates the OSTH407705C is no longer manufactured or actively supported by On Shore Technology Inc. The HW0770020000G from Amphenol Anytek provides equivalent functionality with active product status and ongoing supply availability.
