Substitute Part Grouping Explanation

Substitution eligibility for the OSTH423705C is determined by strict alignment across the following critical parameters:

Position Count & Pitch: The substitute must maintain 23 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.

Connector Type & Termination: Both the main part and substitute must be plug-type connectors with female sockets and push-in spring termination to maintain functional equivalence in circuit applications.

Electrical Specifications: Voltage rating of 300 V UL and wire gauge compatibility (12-26 AWG) must be preserved to ensure safe operation within the original design parameters.

Physical Configuration: Free hanging (in-line) mounting type and thermoplastic housing with phosphor bronze contacts establish the baseline mechanical and material requirements.

Compliance & Status: Active product status with ROHS3 compliance and REACH unaffected designation ensures regulatory alignment and supply chain continuity.

The HW2370020000G from Amphenol Anytek meets all substitution criteria while offering enhanced specifications in operating temperature range and current rating.

Engineering Selection Recommendations

The HW2370020000G qualifies as a direct substitute for the OSTH423705C based on complete parameter alignment across all critical electrical and mechanical specifications. Both components maintain identical position count, pitch spacing, termination methodology, and voltage/current handling capacity.

The substitute part offers operational advantages through an extended temperature range (-40°C to 115°C versus -30°C to 105°C) and specified current rating of 10 A UL, providing enhanced performance margins for demanding applications. Both parts maintain equivalent compliance certifications: ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability rating.

The transition from obsolete to active product status with the HW2370020000G ensures long-term supply chain availability and continued manufacturer support. Current inventory levels (958 pcs for HW2370020000G versus 834 pcs for OSTH423705C) support immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can HW2370020000G directly replace OSTH423705C in existing designs?

A: Yes. Both components share identical position count (23), pitch spacing (5.00mm), connector type (plug with female sockets), termination style (push-in spring), and electrical ratings (300V, 12-26 AWG). Mechanical and electrical compatibility is complete.

Q: What is the primary difference between these two parts?

A: The HW2370020000G features a 180° wire entry orientation compared to the OSTH423705C's 90° orientation. This represents a physical configuration difference that may require harness routing adjustments during integration. The substitute also provides extended operating temperature range (-40°C to 115°C) and specified current rating (10 A UL).

Q: Why is the OSTH423705C classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The HW2370020000G from Amphenol Anytek maintains active production status with equivalent functionality, making it the recommended alternative for new designs and ongoing system support.

Q: Are there packaging differences between these parts?

A: The OSTH423705C is supplied in standard packaging, while HW2370020000G is packaged in bulk format. Both are suitable for production environments; bulk packaging may offer cost advantages for high-volume applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Electrical safety and environmental compliance are equivalent.

Q: What wire gauge compatibility exists for these terminal blocks?

A: Both parts accept wire gauges from 12-26 AWG, ensuring compatibility with standard industrial wiring practices and existing harness designs.
