OSTTS04115B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS04115B is a 4-position terminal block plug manufactured by On-Shore Technology, featuring female sockets with 0.138" (4.60mm) pitch spacing. This component is designed for free-hanging (in-line) applications with screw termination and operates across -40°C to 115°C. The part is currently active in production with 1096 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct functional replacement in applications where the core performance requirements remain constant.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS04115B is determined by alignment across the following critical parameters:

Position Count & Pitch: Both main and substitute parts must maintain 4 positions at 0.138" (4.60mm) spacing to ensure mechanical compatibility with mating connectors.
Connector Type: Female socket configuration required for functional equivalence.
Voltage Rating: Minimum 300 V UL rating to meet electrical safety requirements.
Wire Gauge Compatibility: Support for 16-28 AWG wire range to accommodate standard conductor sizes.
Operating Temperature Range: -40°C to 115°C minimum to ensure thermal performance across specified environments.
Termination Method: Screw-based termination to maintain installation consistency.
Mounting Configuration: Free-hanging (in-line) orientation for direct form-factor replacement.
Compliance: ROHS3 compliance and REACH unaffected status required for regulatory alignment.

The substitute part TS04115A0000G meets these criteria with allowable variations in wire gauge range (0.5-1.5mm²), termination mechanism detail (rising cage clamp), and contact material composition, while maintaining functional equivalence.

Engineering Selection Recommendations

Both the OSTTS04115B and TS04115A0000G maintain active product status with full ROHS3 compliance and REACH unaffected designation, ensuring regulatory alignment for current applications.

The TS04115A0000G substitute introduces a rising cage clamp termination mechanism in place of standard screw termination and expands wire gauge range to 0.5-1.5mm². These variations do not compromise functional equivalence when wire gauges remain within the overlapping 1.0-1.5mm² range. The substitute part includes UL94 V-0 material flammability rating and specified insulation height (0.760"), providing additional material documentation.

Selection between these parts should be based on connector inventory availability, lead time requirements, and specific application constraints regarding termination method preference and wire gauge specifications.

Frequently Asked Questions (FAQ)

Q: Can TS04115A0000G directly replace OSTTS04115B in existing designs?

A: Yes, when wire gauges remain within the 1.0-1.5mm² overlap range. The 4-position, 4.60mm pitch configuration, voltage rating, temperature range, and mounting type are identical. The rising cage clamp termination mechanism functions equivalently to screw termination for this connector class.

Q: What is the difference in wire gauge specifications between these parts?

A: OSTTS04115B supports 1.5mm² maximum, while TS04115A0000G supports 0.5-1.5mm². Both accommodate 16-28 AWG wire. Applications using wire gauges below 1.0mm² require the TS04115A0000G substitute.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -40°C to 115°C, ensuring thermal compatibility across standard industrial and commercial environments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. MSL rating is 1 (Unlimited) for both parts.

Q: What is the significance of the rising cage clamp termination in TS04115A0000G?

A: Rising cage clamp termination provides an alternative screw-based connection method that maintains the same 0.2 Nm torque specification and wire strip length (6-7mm) as the main part, ensuring installation consistency.

Q: Are there inventory considerations when selecting between these parts?

A: OSTTS04115B has 1096 units in stock, while TS04115A0000G has 1439 units available. Selection may depend on lead time requirements and supply chain priorities.
