OSTHP115052 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTHP115052 is an 11-position terminal block plug manufactured by On-Shore Technology, 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 eligibility for the OSTHP115052 is determined by strict alignment of the following critical parameters:

• Position Count: Must be 11 positions
• Pitch Spacing: Must be 0.200" (5.08mm)
• Connector Type: Must be plug with female sockets
• Termination Method: Must be IDC
• Mounting Configuration: Must be free hanging (in-line)
• Voltage Rating: Must meet or exceed 300V UL specification
• Wire Gauge Compatibility: Must support 18-22 AWG
• Flammability Compliance: Must maintain UL94 V-0 rating
• Environmental Compliance: Must be RoHS compliant

The Phoenix Contact 1883446 satisfies all substitution criteria through matching position count, pitch, connector type, termination style, and mounting configuration. Additional electrical specifications (10A current rating, 1kV IEC voltage) and material composition (polyamide housing) provide equivalent or enhanced performance characteristics within the defined parameter set.

Engineering Selection Recommendations

The Phoenix Contact 1883446 (COMBICON QC series) is the designated manufacturer-recommended substitute for the obsolete OSTHP115052. Selection of this alternative is supported by:

• Active Product Status: The 1883446 maintains active production status, ensuring long-term availability and supply chain continuity.
• Compliance Alignment: Both components maintain UL94 V-0 flammability ratings and RoHS compliance, satisfying regulatory requirements for equivalent applications.
• Electrical Equivalence: Matching voltage (300V UL), current capacity (10A), and wire gauge specifications (18-22 AWG) ensure functional interchangeability in existing circuit designs.
• Mechanical Compatibility: Identical pitch spacing (5.08mm), position count (11), and mounting configuration (free hanging, in-line) guarantee physical fit within existing connector housings and harness assemblies.
• Enhanced Material Specification: Polyamide (PA) nylon housing provides equivalent or superior thermal and mechanical performance compared to generic thermoplastic construction.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1883446 be used as a direct replacement for OSTHP115052 in existing assemblies?

A: Yes. The 1883446 matches all critical substitution parameters: 11 positions, 5.08mm pitch, IDC termination, free hanging mounting, 300V UL rating, and 18-22 AWG wire gauge compatibility. No mechanical or electrical modifications are required.

Q: What is the significance of the 180° plug wire entry specification on the 1883446?

A: The 180° wire entry orientation describes the connector's mating angle relative to the housing. This parameter does not affect substitution eligibility, as the OSTHP115052 specification does not define wire entry angle. Both components function identically in free hanging (in-line) configurations.

Q: Are there compliance differences between ROHS3 and RoHS designations?

A: ROHS3 Compliant and RoHS Compliant both indicate compliance with Restriction of Hazardous Substances regulations. The 1883446's RoHS Compliant status satisfies the same regulatory requirements as the OSTHP115052's ROHS3 designation for equivalent applications.

Q: Does the polyamide housing material of the 1883446 affect performance compared to the thermoplastic housing of OSTHP115052?

A: No. Both materials maintain UL94 V-0 flammability ratings and support identical operating temperature ranges (-30°C to 105°C). Polyamide provides equivalent thermal and mechanical performance for this application category.

Q: What inventory status should be considered when selecting between these parts?

A: The OSTHP115052 is obsolete with 700 pieces in stock. The Phoenix Contact 1883446 is active production with 745 pieces available. For new designs and long-term applications, the 1883446 is the appropriate selection due to active manufacturer support and ongoing availability.
