OSTTS04715D Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS04715D is a 4-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 270° wire entry orientation. This component is designed for free-hanging (in-line) mounting 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 alternative manufacturers offer terminal block plugs with compatible electrical ratings, mechanical dimensions, and termination methods that satisfy the same application requirements.

Engineering Selection Recommendations

Both the OSTTS04715D and 1835494 maintain active product status and satisfy RoHS3 and REACH compliance requirements. Selection between these parts depends on application-specific mechanical constraints:

The OSTTS04715D is appropriate for applications requiring 270° wire entry orientation with standard screw termination and operating temperatures up to 105°C.

The 1835494 is appropriate for applications accommodating 90° wire entry orientation and benefiting from rising cage clamp termination, which provides enhanced wire retention. The 1835494 supports an extended wire gauge range (12-30 AWG) and carries IEC current rating of 12A, providing additional electrical specification documentation.

Both parts share identical pitch spacing (5.00mm), position count (4), socket type (female), mounting method (free-hanging in-line), voltage rating (300V UL), and flammability classification (UL94 V-0). Wire gauge overlap exists within the 12-24 AWG range specified for the OSTTS04715D.

Frequently Asked Questions (FAQ)

Q: Can the 1835494 directly replace the OSTTS04715D in existing installations?

A: Direct mechanical replacement requires verification of wire entry orientation compatibility. The OSTTS04715D features 270° wire entry, while the 1835494 features 90° wire entry. If the application's physical layout accommodates the 90° orientation change, electrical and functional compatibility is established through matching pitch (5.00mm), position count (4), socket type (female), voltage rating (300V UL), and flammability rating (UL94 V-0).

Q: Are there wire gauge limitations when substituting?

A: The OSTTS04715D accepts 12-24 AWG (0.34-2.5mm²). The 1835494 accepts 12-30 AWG (0.2-2.5mm²). Wires within the 12-24 AWG range are compatible with both parts. Wires between 24-30 AWG are compatible only with the 1835494.

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

A: Both are screw-based termination methods. Standard screw termination requires manual wire insertion and screw tightening. Rising cage clamp termination integrates a mechanical cage that rises as the screw tightens, providing automatic wire retention and reducing manual handling steps. The 1835494 uses rising cage clamp technology.

Q: Do both parts support the same operating temperature range?

A: The OSTTS04715D specifies -30°C to 105°C operating temperature. The 1835494 does not provide an operating temperature specification in the available data. Applications requiring documented temperature range performance should reference the OSTTS04715D.

Q: Are both parts available in the same packaging format?

A: Both parts are supplied in bulk packaging format, consistent with standard terminal block component distribution.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS3 compliant, REACH unaffected, classified as EAR99 for export control purposes, and carry HTSUS code 8536.90.4000 for tariff classification.
