OSTTS08715B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS08715B is an 8-position terminal block plug manufactured by On Shore Technology Inc., designed for screw-terminated connections with 0.197" (5.00mm) pitch spacing. This component features female sockets with free-hanging (in-line) mounting orientation and supports wire gauges from 12-24 AWG (0.34-2.5mm²). The part is actively produced and maintains RoHS3 compliance with UL94 V-0 flammability rating.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's core specifications, enabling direct replacement in applications where form factor variations are acceptable.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1912359 qualifies as a substitute based on the following alignment of critical parameters:

• Position Count & Pitch: Both parts feature 8 positions at 0.197" (5.00mm) pitch, ensuring mechanical compatibility with mating connectors
• Type & Termination: Both are plug-type female socket configurations with screw-based termination methods
• Mounting Configuration: Both utilize free-hanging (in-line) mounting orientation
• Voltage Rating: Both support 300 V UL rating, meeting the same electrical safety requirements
• Wire Gauge Compatibility: The substitute accepts 12-30 AWG (0.2-2.5mm²), which encompasses the main part's 12-24 AWG range
• Compliance & Safety: Both maintain RoHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1)

The primary difference is the plug wire entry orientation (90° vs. 270°), which affects physical installation geometry but does not alter electrical or core mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTS08715B and 1912359 maintain active product status with full RoHS3 compliance and UL94 V-0 certification. Selection between these parts should be based on installation geometry requirements:

• OSTTS08715B (270° wire entry): Select when wire routing requires the connector orientation specified in the original design
• 1912359 (90° wire entry): Select when 90° wire entry geometry is compatible with the application layout and when extended wire gauge range (12-30 AWG) provides operational flexibility

Both parts satisfy identical electrical safety requirements (300 V UL) and environmental compliance standards. The rising cage clamp termination in the substitute part provides an alternative to standard screw termination while maintaining equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1912359 directly replace the OSTTS08715B in existing assemblies?

A: Electrical and mechanical compatibility is confirmed for the 8-position, 5.00mm pitch configuration. Physical installation feasibility depends on wire entry orientation (90° vs. 270°) and available space in the enclosure or panel.

Q: Are there wire gauge limitations when substituting?

A: The OSTTS08715B accepts 12-24 AWG. The 1912359 accepts 12-30 AWG, providing broader compatibility. Both support the same maximum wire cross-section of 2.5mm².

Q: Do both parts meet the same safety and compliance standards?

A: Yes. Both parts are RoHS3 compliant, carry UL94 V-0 flammability rating, maintain REACH unaffected status, and support 300 V UL voltage rating.

Q: What is the difference in termination methods?

A: The OSTTS08715B uses standard screw termination. The 1912359 uses screw-based rising cage clamp termination, which provides wire retention latches on the wire side. Both are screw-terminated connection methods suitable for equivalent applications.

Q: Are there packaging or inventory considerations?

A: Both parts are available in bulk packaging. Verify current inventory status and lead times with your supplier, as availability may vary by region and order volume.
