OSTTS02515D Terminal Block Plug Equivalent & Substitute Parts
Part Overview
The OSTTS02515D is a 2-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 from 12-24 AWG (0.34-2.5mm²). The part maintains Active product status and is RoHS3 compliant with UL94 V-0 flammability rating.
Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement while maintaining system compatibility and performance specifications.

Substitute Part Grouping Explanation
Substitution eligibility for the OSTTS02515D is determined by the following critical parameters:
- Position Count & Pitch: Substitute must maintain 2 positions at 0.200" (5.08mm) spacing for mechanical compatibility with mating connectors
- Connector Type: Female socket plugs only; maintains gender compatibility in the connection interface
- Termination Method: Screw-based termination required for wire attachment consistency
- Mounting Configuration: Free-hanging in-line orientation for identical installation geometry
- Wire Gauge Compatibility: Substitute wire gauge range must accommodate 12-24 AWG minimum requirement
- Voltage Rating: Substitute voltage rating must meet or exceed 300 V UL specification
- Flammability & Compliance: UL94 V-0 and RoHS3 compliance required for regulatory equivalence
The substitute part 1912621 (Phoenix Contact COMBICON MVSTBR series) satisfies these core substitution criteria while introducing enhanced specifications in current rating and termination technology.

Engineering Selection Recommendations
Both the OSTTS02515D and substitute 1912621 maintain Active product status with full RoHS3 and UL94 V-0 compliance, ensuring regulatory equivalence for applications requiring these certifications.
The OSTTS02515D provides baseline screw termination with standard specifications across the 12-24 AWG wire range. The 1912621 substitute offers enhanced wire gauge accommodation (12-30 AWG) and rising cage clamp termination technology while maintaining identical pitch, position count, voltage rating, and flammability classification.
Selection between these parts depends on application-specific requirements: the OSTTS02515D for standard screw termination applications, or the 1912621 for installations requiring extended wire gauge flexibility or enhanced cage clamp termination security.
Frequently Asked Questions (FAQ)
Q: Can the 1912621 directly replace the OSTTS02515D in existing assemblies?
A: Yes. Both parts maintain identical 2-position configuration at 0.200" (5.08mm) pitch, female socket type, free-hanging in-line mounting, and 300 V UL voltage rating. Mechanical and electrical compatibility is confirmed across these core parameters.
Q: What is the difference in termination technology between these parts?
A: The OSTTS02515D uses standard screw termination. The 1912621 employs rising cage clamp screw termination, which provides enhanced wire retention through spring-loaded contact mechanisms while maintaining screw-based adjustment.
Q: Does the extended wire gauge range of the 1912621 affect compatibility?
A: No. The 1912621 wire gauge range (12-30 AWG) encompasses the OSTTS02515D requirement (12-24 AWG). Applications using 12-24 AWG wire remain fully compatible with identical electrical performance.
Q: Are there packaging or inventory considerations for substitution?
A: Both parts are supplied in bulk packaging. Current inventory shows 857 pcs for OSTTS02515D and 1262 pcs for 1912621. Substitution does not introduce packaging compatibility issues.
Q: Do both parts meet the same regulatory and compliance standards?
A: Yes. Both parts are RoHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.90.4000) codes.
