OSTH422705C Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH422705C is a 22-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 90° wire entry orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The part is designed for free-hanging (in-line) mounting applications with screwless push-in spring termination, suitable for wire gauges 12-26 AWG and operating temperatures from -30°C to 105°C.

Substitute Part Grouping Explanation

Substitution of the OSTH422705C is determined by strict equivalence across the following critical parameters:

Position Count & Pitch: Both main and substitute parts must maintain 22 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
Connector Type: Female socket configuration is required for functional interchangeability.
Termination Method: Screwless push-in spring termination must be preserved to maintain installation compatibility.
Mounting Configuration: Free-hanging (in-line) mounting type is mandatory.
Electrical Ratings: Voltage rating of 300 V UL and wire gauge compatibility (12-26 AWG) must be maintained or exceeded.
Material & Compliance: Contact material (Phosphor Bronze), housing material (Thermoplastic), and UL94 V-0 flammability rating ensure functional equivalence.
Environmental Specifications: Operating temperature range and RoHS3 compliance must be met or exceeded.

The primary difference between the main part and substitute is the wire entry orientation (90° versus 180°), which represents a geometric variation that may require mechanical re-evaluation in specific applications but does not affect electrical performance or core functional parameters.

Engineering Selection Recommendations

The HW2270020000G from Amphenol Anytek qualifies as a functional substitute for the obsolete OSTH422705C based on equivalence across all critical electrical and mechanical parameters. Both components maintain identical position counts, pitch spacing, termination methodology, and material specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The HW2270020000G provides enhanced environmental performance with an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and includes specified current rating (10 A UL) and additional dimensional data (wire strip length 8-9mm, insulation height 0.591"). Both parts maintain ROHS3 compliance and identical flammability ratings.

The primary design difference is wire entry orientation: the OSTH422705C features 90° entry while the HW2270020000G features 180° entry. This geometric variation requires mechanical evaluation within the specific application context to confirm spatial compatibility with existing harness routing and connector positioning.

Frequently Asked Questions (FAQ)

Q: Can HW2270020000G directly replace OSTH422705C in all applications?

A: Electrical and functional compatibility is confirmed across all specified parameters. However, the 180° wire entry orientation of the HW2270020000G differs from the 90° orientation of the OSTH422705C. Physical space constraints and harness routing must be evaluated for each specific installation to confirm mechanical fit.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on equivalence in position count (22), pitch spacing (5.00mm), connector type (female sockets), termination method (screwless push-in spring), mounting configuration (free-hanging in-line), wire gauge compatibility (12-26 AWG), voltage rating (300 V UL), contact material (Phosphor Bronze), housing material (Thermoplastic), and flammability rating (UL94 V-0).

Q: Does the HW2270020000G meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and maintain identical UL94 V-0 flammability ratings. The substitute part exceeds the original operating temperature range and includes specified current rating documentation.

Q: What is the availability status of the substitute part?

A: The HW2270020000G is in active production status with current inventory availability, whereas the OSTH422705C is classified as obsolete. This makes the HW2270020000G suitable for new designs and ongoing procurement requirements.

Q: Are there any packaging differences between these parts?

A: The OSTH422705C packaging is unspecified in available documentation. The HW2270020000G is supplied in bulk packaging. Confirm packaging requirements for your specific procurement and assembly processes.
