ED950/9 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The ED950/9 is a 9-position terminal block plug manufactured by On Shore Technology Inc., designed for screw-terminated connections with female sockets at 5mm pitch. This component is classified as Active and maintains full RoHS3 compliance. Terminal block plugs serve as critical interconnection components in industrial control systems, power distribution panels, and modular equipment where reliable, field-serviceable connections are required. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ED950/9 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 9 (fixed requirement)
• Pitch: 0.197" (5.00mm) (fixed requirement)
• Type: Plug with female sockets (fixed requirement)
• Mounting: Free hanging (in-line) configuration (fixed requirement)
• Termination: Screw-based connection method (fixed requirement)

Allowable Parameter Ranges for Substitution:

• Wire gauge range: Must accommodate 12 AWG minimum; upper limit may extend beyond 22 AWG
• Voltage rating: Must meet or exceed 300 V UL specification
• Current rating: Must meet or exceed 15 A UL specification
• Operating temperature: Must encompass or exceed -30°C to 105°C range
• Material flammability: Must maintain UL94 V-0 rating
• Regulatory compliance: RoHS3 and REACH status must be maintained

The identified substitute parts (OSTTJ097150 and 796640-9) satisfy these core compatibility requirements while offering variations in contact materials, wire gauge acceptance ranges, and thermal operating windows.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and meet the core electrical and mechanical requirements for 9-position, 5mm-pitch terminal block plug applications.

ED950/9 (Primary Part): Maintains the original specification with copper contacts and standard polyamide housing. Suitable for applications requiring the specified wire gauge range of 12-22 AWG and operating temperature window of -30°C to 105°C.

OSTTJ097150 (Substitute): Offers extended wire gauge acceptance (12-30 AWG) and broader operating temperature range (-40°C to 115°C). Contact material is brass rather than copper. Housing material specification differs from the primary part. RoHS3 compliance is maintained. This substitute accommodates applications requiring finer wire gauges or extended thermal operating windows.

796640-9: Manufactured by TE Connectivity, this part features rising cage clamp termination technology in addition to screw termination, phosphor bronze contacts, and PA66 nylon housing. Supports the widest wire gauge range (12-30 AWG, 0.05-3mm²) and extended operating temperature (-40°C to 110°C). Includes side stacking capability and tin contact mating finish. RoHS compliance is maintained; REACH status is affected. This substitute is suitable for applications requiring enhanced termination security and broader wire gauge compatibility.

Selection should be based on specific application requirements regarding wire gauge, operating temperature, and termination method preferences.

Frequently Asked Questions (FAQ)

Q: Can OSTTJ097150 be used as a direct replacement for ED950/9?

A: OSTTJ097150 is electrically and mechanically compatible as a substitute. Both maintain 9 positions at 5mm pitch, screw termination, and 300V UL rating. The primary differences are contact material (brass vs. copper), extended wire gauge range (12-30 AWG vs. 12-22 AWG), and broader operating temperature (-40°C to 115°C vs. -30°C to 105°C). Substitution is valid when application requirements fall within OSTTJ097150 specifications.

Q: What is the difference between the termination methods in 796640-9 compared to ED950/9?

A: ED950/9 uses standard screw termination. The 796640-9 employs rising cage clamp technology combined with screw termination, providing enhanced wire retention and reduced risk of wire displacement during operation. Both achieve the same 15A current rating and 300V voltage rating. The rising cage clamp method may require different installation procedures.

Q: Are all three parts RoHS compliant?

A: ED950/9 and OSTTJ097150 are ROHS3 compliant. The 796640-9 is RoHS compliant but carries REACH Affected status, whereas the other two are REACH Unaffected. Regulatory requirements of the end application should determine which part is appropriate.

Q: Can finer wire gauges (smaller than 12 AWG) be used with these terminal blocks?

A: The ED950/9 specification limits wire gauge to 12-22 AWG. OSTTJ097150 and 796640-9 accept wire gauges down to 12 AWG minimum (with extended upper ranges). None of these parts are specified for wire gauges finer than 12 AWG. Application requirements demanding finer wire gauges require alternative component selection.

Q: What is the significance of the different screw torque specifications?

A: ED950/9 specifies 0.5 Nm (4.4 Lb-In), OSTTJ097150 specifies 0.56 Nm (5.0 Lb-In), and 796640-9 specifies 0.79 Nm (7.0 Lb-In). These values represent the recommended tightening torque for screw terminals. Exceeding specified torque may damage contacts or housing; insufficient torque may result in poor electrical connection. Installation procedures must follow the specific part's torque requirements.

Q: Which substitute part supports the widest operating temperature range?

A: OSTTJ097150 supports -40°C to 115°C, which is the broadest range among the three parts. ED950/9 operates from -30°C to 105°C, and 796640-9 operates from -40°C to 110°C. Application thermal requirements should guide selection.
