OSTTS04515D Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS04515D is a 4-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.200" (5.08mm) pitch spacing. This component is designed for free-hanging (in-line) applications requiring screw termination with wire gauges between 12-24 AWG (0.34-2.5mm²). The part maintains Active product status and is RoHS3 compliant with UL94 V-0 flammability rating.

Equivalent and substitute parts are identified when they maintain compatibility across critical electrical and mechanical parameters including pitch spacing, number of positions, termination method, voltage rating, wire gauge compatibility, and mounting configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS04515D is determined by strict alignment of the following critical parameters:

Pitch and Position Count: Substitute parts must maintain 0.200" (5.08mm) pitch with 4 positions to ensure mechanical and electrical compatibility with mating connectors.
Connector Type: Female socket plugs with free-hanging (in-line) mounting configuration are required.
Termination Method: Screw-based termination is the primary requirement; alternative screw mechanisms (such as rising cage clamp) are acceptable if they maintain functional equivalence.
Voltage Rating: Minimum UL voltage rating of 300 V is required.
Wire Gauge Compatibility: Wire gauge range must accommodate 12-24 AWG (0.34-2.5mm²) or broader ranges that encompass this specification.
Flammability and Compliance: UL94 V-0 rating and RoHS3 compliance are mandatory.

The Phoenix Contact 1913086 qualifies as a substitute part based on these criteria.

Engineering Selection Recommendations

Both the OSTTS04515D and Phoenix Contact 1913086 maintain Active product status and satisfy all mandatory compliance requirements including RoHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status. Both components are classified under identical HTSUS and ECCN codes.

The Phoenix Contact 1913086 provides expanded wire gauge compatibility (12-30 AWG versus 12-24 AWG) and incorporates rising cage clamp termination technology in addition to standard screw termination. The 1913086 also specifies IEC current and voltage ratings (16A at 630V IEC) in addition to UL ratings, providing broader international application scope.

Selection between these parts should be based on specific application requirements regarding wire gauge range, termination mechanism preference, and regional compliance standards.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1913086 directly replace the OSTTS04515D in existing installations?

A: Yes, provided the mating connector is compatible with the 0.200" (5.08mm) pitch and 4-position configuration. The rising cage clamp termination in the 1913086 is functionally equivalent to standard screw termination for this application class.

Q: What is the significance of the expanded wire gauge range in the 1913086?

A: The 1913086 accommodates wire gauges from 12-30 AWG (0.2-2.5mm²), compared to the OSTTS04515D range of 12-24 AWG (0.34-2.5mm²). This provides flexibility for applications using smaller gauge conductors while maintaining full compatibility with the OSTTS04515D wire range.

Q: Are there differences in screw torque specifications between these parts?

A: Yes. The OSTTS04515D specifies 0.4 Nm (4.6 Lb-In) torque, while the 1913086 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In). Installation procedures must follow the respective manufacturer specifications.

Q: Do both parts meet the same voltage and temperature requirements?

A: Both parts are rated for 300V UL and maintain UL94 V-0 flammability rating. Operating temperature specifications differ: the OSTTS04515D specifies -30°C to 105°C, while the 1913086 does not provide an operating temperature range in the available data.

Q: What packaging and inventory considerations apply?

A: The OSTTS04515D is available in bulk packaging with 993 pieces in stock. The Phoenix Contact 1913086 is also available in bulk packaging with 1127 pieces in stock. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.
