OSTH416705B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH416705B is a 16-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 270° wire entry orientation. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The plug utilizes screwless push-in spring termination and is rated for 300V UL operation across a wire gauge range of 12-26 AWG, with operating temperature limits of -30°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH416705B is determined by strict alignment of the following critical parameters:

Position Count & Pitch: The substitute must maintain 16 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connector housings.

Connector Type & Gender: Both the main part and substitute must be plug-type connectors with female sockets to maintain proper mating orientation.

Termination Method: Screwless push-in spring termination is required for compatibility with existing wiring practices and installation procedures.

Mounting Configuration: Free hanging (in-line) mounting type must be preserved to maintain form factor consistency.

Electrical Ratings: Voltage rating of 300V UL and wire gauge compatibility of 12-26 AWG establish the minimum electrical performance envelope.

Material & Compliance: UL94 V-0 flammability rating and RoHS compliance ensure regulatory and safety standard alignment.

The Phoenix Contact 1974876 qualifies as a manufacturer-recommended substitute based on these criteria, with enhanced electrical specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1974876 is the manufacturer-recommended substitute for the obsolete OSTH416705B. Both components meet identical electrical and mechanical specifications for position count, pitch, termination method, mounting configuration, and voltage rating. The substitute maintains UL94 V-0 flammability compliance and RoHS certification status.

The primary difference between the two parts is wire entry orientation: the OSTH416705B features 270° entry while the 1974876 provides 180° entry. This difference must be evaluated against the specific installation geometry and wiring layout of the target application. Both configurations support the same wire gauge range (12-26 AWG) and operating temperature envelope (-30°C to 105°C).

The active product status of the 1974876 ensures ongoing availability and manufacturer support, eliminating supply chain risk associated with the obsolete OSTH416705B.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1974876 be used as a direct replacement for the OSTH416705B?

A: The 1974876 is electrically and mechanically compatible based on position count, pitch, termination style, and voltage rating. The wire entry angle differs (180° versus 270°), requiring verification that the substitute's orientation accommodates the existing wiring layout and installation space.

Q: What are the critical compatibility parameters for this terminal block plug category?

A: Position count (16), pitch spacing (5.00mm), connector gender (female sockets), termination method (push-in spring), and mounting type (free hanging) are the primary determinants of substitution eligibility. Voltage rating and wire gauge compatibility must also align.

Q: Does the substitute maintain the same safety and compliance certifications?

A: Yes. Both the OSTH416705B and 1974876 meet UL94 V-0 flammability requirements and RoHS compliance standards. The substitute carries active RoHS certification while the original part is ROHS3 compliant.

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

A: Wire entry angle (270° versus 180°) affects the physical orientation of incoming wires relative to the connector body. This parameter must be evaluated against the specific installation geometry, available space, and wiring routing requirements of the target application.

Q: Is the substitute available in the same packaging format?

A: The OSTH416705B is supplied in standard packaging, while the 1974876 is available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.
