OSTH404705D Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTH404705D is a 4-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 270° wire entry orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part supports wire gauges from 12-26 AWG with screwless push-in spring termination and operates across a temperature range of -30°C to 105°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH404705D is determined by strict alignment across the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 4 positions with 0.197" (5.00mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors.
• Connector Type: Female socket plugs with identical termination methodology (screwless push-in spring) are required for direct replacement.
• Voltage & Current Rating: Substitute parts must meet or exceed the 300 V UL voltage specification.
• Wire Gauge Compatibility: Support for 12-26 AWG wire range ensures compatibility with existing wiring harnesses.
• Mounting Configuration: Free hanging (in-line) mounting type must be preserved.
• Compliance Standards: RoHS3 compliance and UL94 V-0 flammability rating are mandatory for equivalent substitution.

The HW0470520000G from Amphenol Anytek qualifies as a substitute based on these parameters, with the primary difference being wire entry orientation (180° versus 270°), which represents a mechanical variation rather than a functional incompatibility in applications where connector orientation can be accommodated.

Parameter Comparison

Engineering Selection Recommendations

The HW0470520000G represents a functionally equivalent substitute for the obsolete OSTH404705D based on alignment of core electrical and mechanical specifications. Both components maintain identical pitch spacing, position count, termination methodology, voltage rating, wire gauge compatibility, and compliance certifications (RoHS3, UL94 V-0).

The primary distinction is wire entry orientation: the OSTH404705D features 270° entry while the HW0470520000G provides 180° entry. This difference is a mechanical consideration rather than an electrical limitation. Selection of the HW0470520000G is appropriate for applications where connector orientation can be adjusted to accommodate the 180° wire entry configuration.

The HW0470520000G carries active product status, ensuring ongoing availability and supply chain continuity. Its extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) provides additional thermal margin for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the HW0470520000G directly replace the OSTH404705D without modification?

A: Direct mechanical replacement is possible if the 180° wire entry orientation is compatible with your application layout. The electrical and functional characteristics are equivalent. If the 270° orientation is a hard requirement, physical adapter solutions or harness reconfiguration may be necessary.

Q: Are the pitch and position specifications identical between these parts?

A: Yes. Both components feature 4 positions with 0.197" (5.00mm) pitch spacing, ensuring compatibility with mating connectors designed for either part.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the OSTH404705D and HW0470520000G accept 12-26 AWG wire, maintaining compatibility with existing wiring harnesses.

Q: What is the significance of the product status difference?

A: The OSTH404705D is obsolete, indicating discontinued manufacturing and limited availability. The HW0470520000G is active, ensuring reliable supply and ongoing manufacturer support for future procurement.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are RoHS3 compliant and carry UL94 V-0 flammability ratings, meeting identical regulatory and safety standards.

Q: Does the HW0470520000G operate across a wider temperature range?

A: Yes. The HW0470520000G operates from -40°C to 115°C compared to the OSTH404705D range of -30°C to 105°C, providing extended thermal performance capability.
