OSTHP135052 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTHP135052 is a 13-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.200" (5.08mm) pitch spacing and IDC termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates within a 300V UL rating and supports 18-22 AWG wire gauges, with an operating temperature range of -30°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHP135052 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 13 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
• Connector Type: Female socket configuration required for direct functional replacement.
• Termination Method: IDC termination style must be preserved for wire attachment compatibility.
• Mounting Configuration: Free hanging (in-line) orientation must be maintained.
• Electrical Ratings: Voltage rating of 300V UL and wire gauge support of 18-22 AWG are minimum requirements.
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating ensure regulatory and safety alignment.

The Phoenix Contact 1883857 qualifies as a direct substitute based on these parameters. While the substitute introduces additional specifications (180° plug wire entry, tin contact mating finish, polyamide housing, and 10A current rating), these represent enhancements that do not compromise backward compatibility with the original OSTHP135052 application.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1883857 is the designated substitute for the obsolete OSTHP135052. Selection of this alternative is supported by:

• Regulatory Compliance: Both parts maintain UL94 V-0 flammability certification and RoHS compliance, ensuring continued adherence to safety and environmental standards.
• Product Status: The substitute is classified as active, providing assured long-term availability and supply chain stability compared to the obsolete original part.
• Functional Equivalence: Matching position count, pitch, termination method, and electrical ratings guarantee direct replacement capability without circuit redesign.
• Enhanced Specifications: The substitute's additional features (180° wire entry orientation, tin contact finish, polyamide housing, and 10A current rating) provide operational improvements while maintaining backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1883857 be used as a direct replacement for OSTHP135052 in existing applications?

A: Yes. Both parts share identical position count (13), pitch spacing (0.200"/5.08mm), termination style (IDC), mounting configuration (free hanging in-line), voltage rating (300V UL), and wire gauge support (18-22 AWG). The substitute meets or exceeds all critical electrical and mechanical parameters of the original part.

Q: What is the significance of the 180° plug wire entry on the substitute part?

A: The 180° wire entry orientation on the Phoenix Contact 1883857 defines the angular approach of the wire harness to the connector. This specification does not affect electrical compatibility but may require verification of physical space constraints in the installation environment.

Q: Are there differences in housing material between the two parts?

A: Yes. The OSTHP135052 uses thermoplastic housing, while the Phoenix Contact 1883857 uses polyamide (PA) nylon. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range (-30°C to 105°C).

Q: Does the 10A current rating on the substitute part affect compatibility?

A: No. The 10A IEC current rating on the Phoenix Contact 1883857 represents an additional specification not present on the original part. This enhancement does not reduce compatibility; it expands the electrical capability of the substitute for applications requiring higher current capacity.

Q: What packaging considerations apply to the substitute part?

A: The Phoenix Contact 1883857 is supplied in bulk packaging, whereas the original OSTHP135052 packaging specification is not detailed. Verify bulk packaging requirements align with procurement and handling procedures for your application.

Q: Are both parts RoHS compliant?

A: Yes. The OSTHP135052 is ROHS3 compliant, and the Phoenix Contact 1883857 is RoHS compliant. Both meet current environmental and hazardous substance restrictions.
