Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH423705B is determined by strict alignment across the following critical parameters:

• Position Count & Pitch: 23 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical and electrical compatibility)
• Socket Type: Female sockets (connector gender requirement)
• Termination Method: Screwless push-in spring mechanism (functional equivalence)
• Mounting Configuration: Free hanging in-line orientation
• Voltage Rating: 300 V UL minimum
• Wire Gauge Compatibility: 12-26 AWG support
• Contact Material: Phosphor bronze (electrical performance baseline)
• Housing Material: Thermoplastic with UL94 V-0 flammability rating
• Regulatory Compliance: ROHS3 and REACH status alignment

The substitute part HW2370010000G (Amphenol Anytek) meets all mandatory electrical and mechanical parameters. The primary difference is plug wire entry orientation (180° versus 270°), which represents a geometric variation that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

The HW2370010000G qualifies as a functional substitute based on electrical and mechanical parameter alignment. The substitute part carries active product status with extended availability (1074 units in stock versus 985 units for the obsolete OSTH423705B), ensuring supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support. The HW2370010000G provides an expanded operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), offering improved thermal performance margins.

The geometric difference in plug wire entry orientation (180° versus 270°) must be evaluated against specific PCB layout and connector housing constraints. This orientation change does not affect electrical performance but requires physical space verification during integration.

Frequently Asked Questions (FAQ)

Q: Can HW2370010000G directly replace OSTH423705B in existing assemblies?

A: Electrical and mechanical compatibility is confirmed across all critical parameters: 23-position count, 5.00mm pitch, female socket configuration, 300V rating, and 12-26 AWG wire gauge support. Physical integration feasibility depends on the 180° versus 270° plug wire entry orientation difference relative to available mounting space and connector housing design.

Q: What is the significance of the plug wire entry angle difference?

A: Plug wire entry angle (180° versus 270°) defines the spatial orientation of the connector relative to the mating housing. This is a geometric parameter that affects board layout and cable routing but does not impact electrical performance, voltage rating, current capacity, or contact integrity.

Q: Are both parts compliant with current regulatory standards?

A: Both OSTH423705B and HW2370010000G maintain ROHS3 compliance and REACH unaffected status. The substitute part (HW2370010000G) carries active product status, ensuring ongoing compliance updates and supply availability.

Q: What is the wire gauge compatibility range for both parts?

A: Both parts support 12-26 AWG wire gauge range, ensuring consistent termination capability across standard industrial wiring specifications.

Q: How do the operating temperature ranges compare?

A: OSTH423705B operates from -30°C to 105°C, while HW2370010000G operates from -40°C to 115°C. The substitute part provides extended thermal operating margins suitable for wider environmental conditions.

Q: Are the contact materials equivalent?

A: Both parts utilize phosphor bronze contacts with tin mating finish, ensuring equivalent electrical conductivity and corrosion resistance characteristics.
