Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHP125052 is determined by strict alignment with the following critical parameters:

Core Compatibility Criteria:

• 12-position configuration with 0.200" (5.08mm) pitch spacing
• Female socket plug type with IDC termination
• Free hanging (in-line) mounting orientation
• 300V minimum voltage rating (UL specification)
• 18-22 AWG wire gauge support
• UL94 V-0 flammability rating
• Operating temperature range encompassing -30°C to 105°C

The substitute part 1883459 (Phoenix Contact COMBICON QC series) meets all mandatory compatibility parameters. While this substitute introduces additional specifications not present in the original part (such as 10A current rating, tin contact mating finish, and polyamide housing material), these enhancements do not conflict with the original design requirements and represent functional improvements within the same electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

The 1883459 (Phoenix Contact) terminal block plug is a direct functional equivalent for OSTHP125052 applications. Selection is based on the following engineering factors:

Product Status Alignment: The substitute part maintains active product status with current manufacturing support, addressing the obsolescence of the original component.

Electrical Compliance: Both parts meet identical UL voltage specifications (300V) and support the same wire gauge range (18-22 AWG). The substitute provides additional current rating specification (10A UL) not declared in the original part, representing enhanced electrical capability within the same form factor.

Regulatory Compliance: Both components maintain UL94 V-0 flammability ratings and RoHS compliance status, ensuring continued suitability for regulated applications.

Mechanical Compatibility: Identical pitch spacing (5.08mm), position count (12), and mounting configuration (free hanging, in-line) ensure direct mechanical interchangeability in existing connector systems.

Material Specification: The substitute's polyamide (nylon) housing material provides equivalent or superior performance compared to the original thermoplastic specification, with maintained operating temperature range compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1883459 be used as a direct replacement for OSTHP125052 in existing assemblies?

A: Yes. Both components share identical pitch spacing (5.08mm), position count (12), termination method (IDC), and mounting configuration (free hanging, in-line). Mechanical and electrical compatibility is confirmed across all specified parameters.

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

A: The 180° wire entry angle on the 1883459 specifies the connector orientation relative to the mating interface. This parameter was not declared in the original OSTHP125052 specification but does not affect functional compatibility when used in applications where wire entry angle is not constrained.

Q: Are there voltage or current limitations when substituting the 1883459?

A: No. The substitute part meets or exceeds the original specification. Both components are rated for 300V UL operation. The substitute provides an additional 10A current rating specification not present in the original part documentation, representing enhanced capability.

Q: How do the housing materials compare between the original and substitute parts?

A: The original OSTHP125052 uses thermoplastic housing, while the 1883459 uses polyamide (nylon). Both materials meet UL94 V-0 flammability requirements and support the identical operating temperature range (-30°C to 105°C), ensuring functional equivalence.

Q: What packaging considerations apply when sourcing the 1883459?

A: The substitute part is available in bulk packaging, compared to the original part's unspecified packaging format. Bulk packaging is standard for terminal block components and does not affect component performance or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The original OSTHP125052 is ROHS3 compliant, and the substitute 1883459 is RoHS compliant. Both meet current regulatory requirements for hazardous substance restrictions.
