Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH423705A is determined by strict alignment across the following critical parameters:

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

Electrical Specifications: Voltage rating of 300 V UL and wire gauge support of 12-26 AWG must be maintained or exceeded to preserve circuit integrity and current-carrying capacity.

Termination and Mounting: Screwless push-in spring termination and free-hanging in-line mounting are required functional characteristics.

Material and Compliance: Contact material (phosphor bronze), housing material (thermoplastic), UL94 V-0 flammability rating, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1) establish the baseline for regulatory and environmental compatibility.

Identified Substitute: HW2370010000G (Amphenol Anytek) meets all critical substitution criteria with the exception of wire entry orientation (180° versus 90°), which represents a mechanical design variation that may require installation assessment based on specific application geometry.

Parameter Comparison

Engineering Selection Recommendations

The HW2370010000G qualifies as a functional equivalent based on alignment of electrical ratings, position count, pitch spacing, termination methodology, and regulatory compliance. The substitute maintains ROHS3 compliance and UL94 V-0 flammability certification, ensuring continued adherence to environmental and safety standards.

The primary design variation is wire entry orientation: the OSTH423705A features 90° entry while the HW2370010000G provides 180° entry. This difference affects physical installation geometry and must be evaluated against specific application constraints, including available mounting space and wire routing requirements.

The HW2370010000G offers an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), providing additional thermal margin for demanding environments. Current rating specification (10 A UL) is provided for the substitute, whereas the original part does not specify current capacity.

Product status transition from obsolete (OSTH423705A) to active (HW2370010000G) ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can HW2370010000G directly replace OSTH423705A without modification?

A: Electrical and functional compatibility is established across all critical parameters. Wire entry orientation differs (180° versus 90°), requiring assessment of installation geometry and wire routing in the specific application. Mechanical fit with existing mating connectors and enclosure design must be confirmed.

Q: Are there compliance or certification differences between these parts?

A: Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1). Regulatory equivalence is established.

Q: What is the significance of the extended operating temperature range in HW2370010000G?

A: The substitute supports -40°C to 115°C versus the original -30°C to 105°C. This expanded range provides additional thermal margin but does not affect compatibility in applications operating within the original temperature specification.

Q: Does wire gauge compatibility remain unchanged?

A: Both parts support 12-26 AWG wire gauges. Wire termination capacity is equivalent.

Q: What packaging differences exist?

A: OSTH423705A is listed without specified packaging; HW2370010000G is supplied in bulk packaging. Procurement quantities and handling procedures may differ accordingly.

Q: Is the 10 A current rating of HW2370010000G a limiting factor?

A: The original OSTH423705A does not specify current capacity. The HW2370010000G 10 A UL rating establishes a defined electrical limit for the substitute and should be evaluated against application current requirements.
