OSTTS16315B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS16315B is a 16-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.150" (3.81mm) pitch spacing. This component is designed for free-hanging (in-line) applications with screw termination and operates across a temperature range of -40°C to 115°C. The part is currently active in production with 899 units in stock.

Alternative equivalent parts are necessary when addressing supply chain constraints, inventory availability, or when design specifications allow for compatible substitutes that meet the same electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS16315B is determined by strict alignment of the following critical parameters:

Position Count & Pitch: All substitutes must maintain 16 positions at 0.150" (3.81mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
Socket Type & Termination: Female socket configuration with screw termination is required for functional equivalence.
Mounting Configuration: Free-hanging (in-line) orientation must be preserved.
Voltage Rating: Minimum 300 V UL rating required.
Wire Gauge Compatibility: Support for 16-28 AWG (1.5mm²) wire range or broader.
Compliance: ROHS3 compliance is mandatory.

The two substitute parts listed (EDZ1710/16 and 1827266) meet these core substitution criteria, though with variations in secondary parameters such as operating temperature range, contact material, and torque specifications.

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance, qualifying them for use in applications requiring regulatory adherence.

OSTTS16315B remains the primary specification with the widest operating temperature range (-40°C to 115°C) and brass housing construction.

EDZ1710/16 provides direct functional equivalence with identical pitch, position count, and wire gauge range. The polyamide housing and higher screw torque specification (0.4 Nm) represent design variations. Operating temperature range is narrower (-30°C to 105°C).

1827266 (Phoenix Contact COMBICON MCVR series) offers expanded wire gauge compatibility (14-30 AWG) and rising cage clamp termination technology. The screw torque specification (0.22-0.25 Nm) aligns closely with the OSTTS16315B. Operating temperature is not specified in the provided data.

Selection between substitutes depends on application-specific requirements for temperature extremes, housing material compatibility, and termination method preferences.

Frequently Asked Questions (FAQ)

Q: Can EDZ1710/16 be used as a direct replacement for OSTTS16315B?

A: EDZ1710/16 meets the core substitution criteria: 16 positions at 3.81mm pitch, female socket configuration, screw termination, 300V UL rating, and 16-28 AWG wire gauge support. The narrower operating temperature range (-30°C to 105°C versus -40°C to 115°C) must be evaluated against application requirements.

Q: What is the primary difference between 1827266 and the other substitutes?

A: The 1827266 features rising cage clamp termination technology in addition to screw termination, and supports a broader wire gauge range (14-30 AWG). These represent design enhancements rather than incompatibilities.

Q: Are all three parts mechanically compatible with the same mating connectors?

A: All three parts maintain 16 positions at 0.150" (3.81mm) pitch with female socket configuration, ensuring mechanical compatibility with standard 3.81mm pitch male header connectors.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.90.4000.

Q: How do screw torque specifications affect component selection?

A: Screw torque values (OSTTS16315B: 0.2 Nm, EDZ1710/16: 0.4 Nm, 1827266: 0.22-0.25 Nm) reflect termination design differences. Selection should align with assembly equipment and wire gauge specifications to prevent under-torque or over-torque conditions.
