OSTTS05515D Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS05515D is a 5-position terminal block plug manufactured by On Shore Technology Inc., designed for free-hanging (in-line) applications with female sockets at 0.200" (5.08mm) pitch. This active product features screw termination, supports wire gauges from 12-24 AWG (0.34-2.5mm²), and operates across -30°C to 105°C. The component is UL94 V-0 rated, ROHS3 compliant, and rated for 300V UL operation.

Substitute parts become necessary when specific application requirements—such as wire entry angle orientation, enhanced current ratings, or cage clamp termination—differ from the standard inline configuration of the OSTTS05515D.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS05515D is determined by the following critical parameters:

• Position Count & Pitch: Both substitute parts maintain 5 positions at 0.200" (5.08mm) pitch, ensuring mechanical and electrical compatibility with mating connectors designed for the OSTTS05515D.
• Type & Mounting: All parts are plug-type with female sockets in free-hanging (in-line) configuration.
• Voltage & Flammability: Substitute parts meet or exceed the 300V UL rating and maintain UL94 V-0 flammability compliance.
• Wire Gauge Compatibility: Substitute parts accept 12-30 AWG (0.2-2.5mm²), which encompasses the OSTTS05515D range of 12-24 AWG (0.34-2.5mm²).
• Regulatory Compliance: All parts are ROHS3 compliant and REACH unaffected.

The two Phoenix Contact substitutes differ from the main part in wire entry angle (90° and 270° orientations versus inline) and termination mechanism (rising cage clamp versus standard screw), but remain functionally equivalent for applications where these variations are acceptable or preferred.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full regulatory compliance (ROHS3, REACH unaffected, EAR99 classification). Selection between the OSTTS05515D and its Phoenix Contact substitutes depends on application-specific wire entry requirements:

• OSTTS05515D: Select for standard inline wire entry configurations with conventional screw termination.
• 1912650: Select for 90° wire entry angle applications requiring rising cage clamp termination and enhanced current rating (16A UL).
• 1913099: Select for 270° wire entry angle applications requiring rising cage clamp termination and enhanced current rating (16A UL).

All parts support the full operating temperature range and maintain equivalent electrical safety ratings. The Phoenix Contact substitutes provide expanded wire gauge acceptance (12-30 AWG versus 12-24 AWG) and cage clamp technology, which may offer improved wire retention in high-vibration environments.

Frequently Asked Questions (FAQ)

Q: Can OSTTS05515D be directly replaced with 1912650 or 1913099?

A: Direct replacement is possible only if the application accommodates the different wire entry angle (90° or 270° versus inline) and cage clamp termination mechanism. The electrical and mechanical interface (5 positions, 0.200" pitch, 300V UL rating) remains compatible with mating connectors designed for the OSTTS05515D.

Q: What is the primary difference between these substitute parts?

A: The OSTTS05515D features inline wire entry with standard screw termination. Part 1912650 provides 90° wire entry with cage clamp termination. Part 1913099 provides 270° wire entry with cage clamp termination. All maintain identical position count and pitch.

Q: Are the Phoenix Contact substitutes rated for higher current?

A: Yes. The Phoenix Contact parts (1912650 and 1913099) are rated for 16A UL current, whereas the OSTTS05515D does not specify a UL current rating. Both maintain 300V UL voltage compatibility.

Q: Do the substitute parts accept the same wire gauges?

A: The Phoenix Contact substitutes accept 12-30 AWG (0.2-2.5mm²), which encompasses the OSTTS05515D range of 12-24 AWG (0.34-2.5mm²). The substitutes provide expanded wire gauge flexibility.

Q: Are all parts compliant with current regulatory standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All maintain UL94 V-0 flammability ratings.

Q: What is the difference between standard screw termination and rising cage clamp termination?

A: Standard screw termination (OSTTS05515D) uses a screw mechanism to secure the wire. Rising cage clamp termination (Phoenix Contact substitutes) uses a spring-loaded cage that rises when the screw is loosened, allowing wire insertion without full screw removal. Cage clamp technology may provide improved wire retention in vibration-prone applications.
