OSTH415705B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH415705B is a 15-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 part operates within a temperature range of -30°C to 105°C and supports wire gauges from 12-26 AWG with push-in spring termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH415705B is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 15 positions with 0.197" (5.00mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors.
• Connector Type: Both main and substitute parts must be terminal block plugs with female sockets and free-hanging (in-line) mounting configuration.
• Termination Method: Push-in spring termination with screwless leg spring design ensures compatibility with existing wiring practices.
• Electrical Ratings: Substitute parts must support minimum 300 V UL rating and accommodate 12-26 AWG wire gauges.
• Environmental Compliance: RoHS compliance and UL94 V-0 flammability rating are required for regulatory alignment.

The Phoenix Contact 1974863 qualifies as a substitute based on these core parameters, despite differences in wire entry angle (180° versus 270°) and additional electrical specifications that exceed the original part's ratings.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1974863 is the designated manufacturer-recommended substitute for the obsolete OSTH415705B. Both components meet identical core electrical and mechanical specifications: 15-position configuration, 5.00mm pitch, push-in spring termination, 300 V UL rating, and 12-26 AWG wire gauge compatibility.

The primary design difference is wire entry orientation: the OSTH415705B features 270° entry while the 1974863 provides 180° entry. This difference requires physical layout evaluation during integration but does not affect electrical performance or connector compatibility.

The 1974863 offers additional advantages through active product status and enhanced electrical ratings (12A IEC current, 630V IEC voltage) that exceed the original specification. Both components maintain UL94 V-0 flammability compliance and tin contact mating finish. The substitute part's RoHS compliance aligns with current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1974863 directly replace the OSTH415705B without modification?

A: The 1974863 is mechanically and electrically compatible for mating with the same connector receptacles. The wire entry angle difference (180° versus 270°) may require physical repositioning within the assembly but does not affect electrical function or contact integrity.

Q: Are the electrical ratings of the 1974863 compatible with systems designed for the OSTH415705B?

A: Yes. The 1974863 meets or exceeds all specified electrical parameters: 300 V UL rating, 12-26 AWG wire gauge support, and tin contact finish. The substitute's additional ratings (12A IEC, 630V IEC) provide enhanced capability without compromising compatibility.

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

A: Wire entry angle (270° versus 180°) determines the physical orientation of the connector during installation. This affects cable routing and assembly layout but not electrical performance. System design must accommodate the 180° entry configuration of the substitute part.

Q: Do both parts meet the same compliance standards?

A: Both components are UL94 V-0 rated and RoHS compliant. The OSTH415705B carries ROHS3 compliance while the 1974863 carries standard RoHS compliance. Both meet current regulatory requirements for their respective product statuses.

Q: Why is the OSTH415705B classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of the product line. The Phoenix Contact 1974863 represents the active equivalent within the terminal block plug category, ensuring continued availability and support for new and replacement applications.
