OSTTS13315B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS13315B is a 13-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 maintains Active product status and is RoHS3 compliant, making it suitable for industrial control and power distribution applications where reliable electrical connections are required across multiple conductor positions.

Substitute parts become necessary when addressing supply chain constraints, lead time requirements, or when design specifications allow for alternative termination methods or wire entry configurations that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS13315B is determined by the following critical parameters that must remain constant or compatible:

• Position Count & Pitch: Substitute must maintain 13 positions at 0.150" (3.81mm) pitch to ensure mechanical and electrical compatibility with mating connectors
• Connector Type: Must be a plug with female sockets to maintain proper mating orientation
• Mounting Configuration: Must support free-hanging in-line mounting to preserve installation geometry
• Voltage Rating: Substitute voltage rating must meet or exceed 300 V UL specification
• Wire Gauge Compatibility: Substitute must accommodate wire gauges within or overlapping the 16-28 AWG range
• Termination Method: Screw-based termination is the primary requirement; alternative screw mechanisms (such as rising cage clamp) are acceptable if they maintain equivalent electrical performance
• Compliance: Both parts must maintain RoHS3 compliance and equivalent regulatory status

The Phoenix Contact 1827237 qualifies as a substitute based on these criteria, offering identical position count, pitch, connector type, and mounting configuration, while providing enhanced wire gauge range and equivalent voltage performance.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTS13315B and 1827237 maintain Active product status with full RoHS3 compliance, ensuring long-term availability and regulatory alignment for industrial applications.

The OSTTS13315B remains the primary specification choice when the original design parameters, including standard wire entry orientation and nickel contact finish, are required for existing installations or when compatibility with existing mating connectors is critical.

The Phoenix Contact 1827237 serves as a qualified substitute when supply constraints necessitate an alternative source. The 1827237 provides expanded wire gauge accommodation (14-30 AWG versus 16-28 AWG), enhanced IEC current rating (8A), and rising cage clamp termination technology. The 90° wire entry configuration represents a geometric difference that must be evaluated against installation space constraints. Both parts maintain equivalent UL voltage ratings (300 V) and identical position/pitch specifications, ensuring electrical compatibility with standard 3.81mm pitch receptacles.

Selection between these parts should be based on availability, lead time requirements, and physical installation geometry constraints related to wire entry orientation.

Frequently Asked Questions (FAQ)

Q: Can the 1827237 directly replace the OSTTS13315B in existing installations?

A: Electrical compatibility is maintained due to identical position count, pitch, voltage rating, and connector type. However, the 90° wire entry orientation on the 1827237 differs from the standard entry on the OSTTS13315B. Physical installation geometry must be verified to ensure the angled entry does not conflict with existing wiring paths or enclosure layouts.

Q: What is the significance of the wire gauge range difference?

A: The OSTTS13315B accommodates 16-28 AWG, while the 1827237 supports 14-30 AWG. The 1827237 provides broader compatibility with both larger conductors (14 AWG) and smaller gauges (30 AWG). If your application uses wire gauges outside the 16-28 AWG range, the 1827237 offers extended flexibility.

Q: Are the termination methods equivalent?

A: Both parts use screw-based termination. The OSTTS13315B employs standard screw termination, while the 1827237 uses rising cage clamp technology. Rising cage clamp provides enhanced contact reliability and simplified wire insertion. Both methods achieve equivalent electrical performance for this application category.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the OSTTS13315B and 1827237 are RoHS3 compliant, REACH unaffected, and classified under the same HTSUS code (8536.90.4000). Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special storage or handling requirements.

Q: What is the impact of different contact finishes?

A: The OSTTS13315B features nickel contact finish, while the 1827237 uses tin finish. Both finishes provide corrosion resistance suitable for industrial environments. Contact finish selection typically depends on application-specific requirements for oxidation resistance and contact resistance stability over time.

Q: Can I use the 1827237 if my design specifies the OSTTS13315B?

A: Substitution requires engineering review to confirm that the 90° wire entry orientation does not conflict with installation constraints and that the rising cage clamp termination method is acceptable for your assembly process. Electrical specifications remain compatible.
