OSTTS14315B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS14315B is a 14-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 requiring screw termination with wire gauges from 16-28 AWG. The part is currently active in production with 1007 units in stock.

Terminal block plugs are essential interconnection components in industrial control systems, power distribution panels, and modular equipment where reliable, field-serviceable connections are required. Equivalent and substitute parts become necessary when managing supply chain continuity, accommodating design revisions, or optimizing procurement across multiple suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS14315B is determined by the following critical parameters that must align with the original specification:

Mandatory Matching Parameters:

• Number of Positions: 14
• Pitch: 0.150" (3.81mm)
• Type: Plug, Female Sockets
• Mounting Type: Free Hanging (In-Line)
• Voltage Rating: Minimum 300 V (UL)

Compatible Variation Parameters:

• Termination Style: Screw-based methods (including rising cage clamp variants)
• Wire Gauge Range: Must accommodate 16-28 AWG minimum
• Operating Temperature: Must support -40°C ~ 115°C range
• Contact Mating Finish: Nickel or Tin acceptable
• Housing Material: Brass or Polyamide (PA) acceptable

The substitute part 1827240 (Phoenix Contact COMBICON MCVR series) meets all mandatory matching parameters and operates within compatible variation ranges, making it a valid electrical and mechanical equivalent for applications requiring OSTTS14315B functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTS14315B and 1827240 are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial applications.

The OSTTS14315B remains the primary specification when original design validation and exact parameter matching are required. The On Shore Technology part carries established field history and is currently in stock with 1007 units available.

The 1827240 (Phoenix Contact) serves as a valid substitute when supply constraints affect the primary part. The Phoenix Contact component offers enhanced wire gauge accommodation (14-30 AWG versus 16-28 AWG) and rising cage clamp termination, which provides improved wire retention characteristics compared to standard screw termination. Both parts maintain equivalent electrical performance at 300 V UL rating and support the same 3.81mm pitch spacing required for connector interchangeability.

Selection between these parts should be based on availability, lead time requirements, and application-specific termination preferences. Both components are suitable for the same mechanical and electrical operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the 1827240 be used as a direct replacement for OSTTS14315B in existing installations?

A: Yes. Both parts share identical position count (14), pitch spacing (3.81mm), socket type (female), mounting configuration (free hanging in-line), and voltage rating (300 V UL). The 1827240 features rising cage clamp termination instead of standard screw termination, which is mechanically and electrically compatible with the same connector interface.

Q: What is the difference between screw termination 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 uses a spring-loaded cage mechanism that opens when the screw is loosened, allowing easier wire insertion and removal while maintaining equivalent electrical contact and current-carrying capacity.

Q: Are the wire gauge ranges compatible between these parts?

A: The OSTTS14315B accepts 16-28 AWG (1.5mm²). The 1827240 accepts 14-30 AWG (0.14-1.5mm²). The 1827240 range is broader and fully encompasses the original specification range, making it compatible for any wire gauge originally specified for the OSTTS14315B.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the OSTTS14315B and 1827240 are ROHS3 compliant and REACH unaffected, meeting current industrial equipment regulatory requirements.

Q: What is the torque specification difference between these parts?

A: The OSTTS14315B specifies 0.2 Nm (1.7 Lb-In) screw torque. The 1827240 specifies 0.22-0.25 Nm (1.9-2.2 Lb-In). These ranges are similar and within acceptable variation for equivalent screw-based termination systems.

Q: Can these parts be intermixed in the same connector housing?

A: No. Each part is a complete plug assembly with integrated housing. They are not interchangeable at the individual component level. However, they are electrically and mechanically equivalent as complete assemblies for applications requiring 14-position, 3.81mm pitch terminal block plugs.
