ED950/20 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The ED950/20 is a 20-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 180° free-hanging in-line mounting. This component is classified as Active product status and is designed for screw-terminated electrical connections in industrial and control applications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling component interchangeability in system designs where inventory or supply constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ED950/20 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 20 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors.
• Connector Type & Mounting: Female socket plugs with free-hanging in-line configuration are required to maintain form factor compatibility.
• Termination Method: Screw termination is mandatory for consistent installation procedures and electrical performance.
• Voltage & Current Ratings: Substitute parts must meet or exceed 300 V UL voltage and 15 A UL current specifications.
• Wire Gauge Compatibility: Acceptable wire gauge ranges must overlap with or encompass the 12-22 AWG specification of the main part.
• Regulatory Compliance: RoHS3 compliance and UL94 V-0 flammability rating are required for equivalent substitution.

The OSTTJ207150 qualifies as a direct substitute based on these parameters, with noted variations in contact material composition and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the ED950/20 and OSTTJ207150 maintain Active product status and satisfy ROHS3 compliance and UL94 V-0 flammability requirements. Selection between these parts should be based on the following criteria:

• Standard Operating Conditions: The ED950/20 is suitable for applications within the -30°C to 105°C temperature range with wire gauges between 12-22 AWG.
• Extended Temperature or Wire Gauge Requirements: The OSTTJ207150 accommodates extended operating temperatures (-40°C to 115°C) and broader wire gauge acceptance (12-30 AWG, 0.34-2.5mm²), making it applicable to more demanding environmental or installation scenarios.
• Material Considerations: The ED950/20 uses copper contacts with polyamide housing, while the OSTTJ207150 uses brass contacts and housing. Material selection should align with application-specific corrosion resistance and thermal conductivity requirements.
• Torque Specification Variance: The OSTTJ207150 specifies 0.56 Nm screw torque compared to the ED950/20's 0.5 Nm. Installation procedures must reflect the appropriate torque value for each part.

Frequently Asked Questions (FAQ)

Q: Can OSTTJ207150 be used as a direct replacement for ED950/20 in existing designs?

A: Yes, the OSTTJ207150 qualifies as a direct substitute based on matching position count, pitch, connector type, mounting configuration, termination method, and voltage/current ratings. However, the difference in contact material (brass vs. copper) and housing material (brass vs. polyamide) should be evaluated for application-specific requirements such as corrosion resistance or thermal performance.

Q: What is the significance of the extended wire gauge range in OSTTJ207150?

A: The OSTTJ207150 accepts wire gauges from 12-30 AWG (0.34-2.5mm²), compared to the ED950/20's 12-22 AWG specification. This extended range provides flexibility for installations using finer gauge wiring, though the ED950/20 remains suitable for applications limited to the 12-22 AWG range.

Q: Are there temperature-related constraints when substituting these parts?

A: The ED950/20 operates within -30°C to 105°C, while the OSTTJ207150 extends to -40°C to 115°C. If an application requires operation below -30°C or above 105°C, the OSTTJ207150 is the appropriate selection. For standard industrial temperature ranges, both parts are functionally equivalent.

Q: How do the screw torque specifications differ between these parts?

A: The ED950/20 specifies 0.5 Nm (4.4 Lb-In) screw torque, while the OSTTJ207150 specifies 0.56 Nm (5.0 Lb-In). Installation procedures must use the correct torque value for each part to ensure proper electrical contact and mechanical security.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes, both the ED950/20 and OSTTJ207150 are ROHS3 compliant, UL94 V-0 rated, and carry identical REACH and ECCN classifications. Both maintain Moisture Sensitivity Level 1 (Unlimited) and are suitable for applications requiring these certifications.
