Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH404705C is determined by the following critical parameters:

• Position Count & Pitch: 4 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical and electrical compatibility)
• Connector Type: Plug with female sockets (required for mating with corresponding receptacles)
• Termination Method: Screwless push-in spring termination (functional equivalence)
• Mounting Configuration: Free hanging in-line orientation
• Electrical Ratings: Minimum 300 V UL voltage rating and support for 12-26 AWG wire gauge
• Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Temperature Range: Must support minimum -30°C to 105°C envelope

The substitute part HW0470520000G from Amphenol Anytek meets these core substitution criteria. The primary difference is wire entry orientation (180° versus 90°), which represents a mechanical variation that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

The HW0470520000G qualifies as a functional substitute based on matching electrical specifications, mechanical configuration, and regulatory compliance. The substitute part carries active product status from Amphenol Anytek, ensuring ongoing availability and supply chain continuity compared to the obsolete OSTH404705C.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. The substitute part provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), offering broader environmental tolerance.

The primary design consideration is wire entry orientation: the OSTH404705C features 90° entry while HW0470520000G features 180° entry. This difference affects physical installation geometry and must be evaluated against specific PCB layout, connector positioning, and cable routing requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can HW0470520000G directly replace OSTH404705C without modification?

A: Both parts share identical position count (4), pitch spacing (5.00mm), termination method (push-in spring), and electrical ratings (300V, 12-26 AWG). The wire entry angle differs (90° versus 180°), requiring assessment of physical installation constraints. Mechanical compatibility depends on connector orientation requirements in the specific application.

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

A: Both parts maintain ROHS3 compliance and UL94 V-0 flammability rating. No compliance gaps exist between the two parts.

Q: What is the significance of the operating temperature range difference?

A: The HW0470520000G supports -40°C to 115°C versus the OSTH404705C range of -30°C to 105°C. The substitute part provides extended low-temperature and high-temperature capability, making it suitable for applications requiring broader thermal operating envelopes.

Q: How does wire entry orientation affect substitution?

A: Wire entry orientation (90° versus 180°) determines the physical direction of cable connection relative to the connector body. This affects PCB layout compatibility, cable routing paths, and connector positioning within the assembly. Application-specific mechanical constraints must be evaluated to confirm suitability.

Q: Is the substitute part currently available?

A: HW0470520000G carries active product status with 631 pieces in stock, ensuring supply availability. The original OSTH404705C is obsolete, making the substitute the recommended path for new procurement.
