OSTTS13715B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS13715B is a 13-position terminal block plug manufactured by On-Shore Technology, designed for screw-terminated electrical connections with 5.00mm pitch spacing. This component is classified as a female socket plug suitable for free-hanging in-line mounting applications. The part is currently in active production status with 649 units available in inventory.

Terminal block plugs require substitute evaluation when original stock becomes unavailable, when supply chain constraints necessitate alternative sourcing, or when design flexibility permits the use of functionally equivalent components from alternative manufacturers. Substitute parts must maintain compatibility across critical electrical and mechanical parameters including position count, pitch spacing, voltage rating, wire gauge compatibility, and termination methodology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS13715B is determined by the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 13 positions with pitch spacing within acceptable tolerance. The OSTTS13715B operates at 0.197" (5.00mm) pitch. The substitute part 1792359 operates at 0.200" (5.08mm) pitch, representing a 0.003" (0.08mm) variance. This minor pitch difference is within mechanical tolerance for free-hanging in-line applications where connector bodies are not rigidly constrained to a fixed header.

Electrical Ratings: The substitute must meet or exceed the voltage requirement of 300 V UL. The OSTTS13715B is rated at 300 V UL; the substitute 1792359 is rated at 300 V UL and 630 V IEC, satisfying this requirement.

Wire Gauge Compatibility: The substitute must accommodate the wire gauge range of 12-24 AWG (0.34-2.5mm²). The OSTTS13715B accepts 12-24 AWG; the substitute 1792359 accepts 12-30 AWG (0.2-2.5mm²), providing full compatibility with the original specification range.

Termination and Mounting: Both parts utilize screw-based termination and free-hanging in-line mounting, ensuring mechanical and functional compatibility.

Regulatory Compliance: Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings, meeting identical compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The OSTTS13715B remains the primary component choice when availability permits, as it is the specified design component with active production status and confirmed inventory of 649 units.

Substitute Selection Criteria: The 1792359 (Phoenix Contact COMBICON MVSTBR series) qualifies as a functional substitute based on the following factors:

• Both parts maintain active production status
• Electrical ratings are equivalent or superior (300 V UL minimum requirement met)
• Wire gauge compatibility is maintained across the specified range (12-24 AWG)
• Pitch variance of 0.003" (0.08mm) is within acceptable mechanical tolerance for free-hanging applications
• Regulatory compliance is identical (ROHS3, REACH unaffected, UL94 V-0)
• Both components utilize screw-based termination with free-hanging in-line mounting

Compliance Verification: Both parts carry identical regulatory certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification, 8536.90.4000 HTSUS code), confirming suitability for equivalent application contexts.

Frequently Asked Questions (FAQ)

Q: Can the 1792359 substitute directly replace the OSTTS13715B in existing designs?

A: The 1792359 is mechanically and electrically compatible for free-hanging in-line applications. The pitch difference of 0.003" (0.08mm) is within tolerance for non-constrained mounting. However, if the connector body is rigidly positioned against a fixed header or mounting surface, physical interference may occur. Mechanical verification is required for constrained mounting scenarios.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm variance represents approximately 1.6% tolerance deviation. For free-hanging applications where connectors mate with corresponding receptacles without rigid positional constraints, this variance is within standard mechanical tolerance. For applications requiring precise pitch alignment with fixed headers, this difference may be significant.

Q: Are the wire gauge ranges compatible?

A: Yes. The OSTTS13715B accepts 12-24 AWG (0.34-2.5mm²). The 1792359 accepts 12-30 AWG (0.2-2.5mm²), providing full coverage of the original specification range with extended capability for smaller gauge wires.

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

A: The OSTTS13715B uses standard screw termination. The 1792359 uses screw-based rising cage clamp termination, which provides additional wire retention features. Both are screw-actuated termination methods suitable for equivalent applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What inventory status should influence component selection?

A: The OSTTS13715B has 649 units in stock; the 1792359 has 800 units in stock. Both parts maintain active production status. Substitute selection should be based on availability requirements and lead time constraints in addition to technical compatibility.
