ED950/14 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The ED950/14 is a 14-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 actively produced and widely used in industrial control, automation, and power distribution applications where screw-terminated connections are required.

Substitute parts become necessary due to inventory constraints, supply chain disruptions, or specific application requirements that may benefit from alternative contact materials or expanded wire gauge compatibility.

Acceptable Variations:

• Contact material (copper, brass, phosphor bronze)
• Housing material (polyamide PA, nylon variants)
• Wire strip length (6-8mm acceptable)
• Screw torque specifications (0.5-0.79 Nm acceptable)
• Plug wire entry angle (180° or unspecified)
• Expanded wire gauge ranges (12-30 AWG acceptable if minimum 12 AWG maintained)

Parameter Comparison

Engineering Selection Recommendations

OSTTJ147150 (On Shore Technology Inc.): This substitute maintains identical pitch, position count, and mounting configuration. Both parts originate from the same manufacturer, ensuring design consistency. The OSTTJ147150 provides expanded wire gauge compatibility (12-30 AWG versus 12-22 AWG) and an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C). The brass contact material and brass housing differ from the ED950/14 copper contacts and polyamide housing. This part is suitable for applications requiring broader wire gauge accommodation or enhanced temperature performance. ROHS3 compliance and UL94 V-0 rating are maintained.

1-796640-4 (TE Connectivity AMP Connectors): This substitute provides identical electrical ratings (15 A, 300 V) and pitch specifications. The rising cage clamp termination method offers an alternative to standard screw termination while maintaining M3 screw compatibility. The phosphor bronze contacts and PA66 nylon housing provide corrosion resistance and mechanical durability. Wire gauge range extends to 12-30 AWG with maximum cross-section of 3mm². Operating temperature range (-40°C to 110°C) exceeds the ED950/14 specification. Retention latches and side stacking features are included. ROHS3 compliance is maintained; however, REACH status is affected (versus unaffected for ED950/14). This part is suitable for applications requiring enhanced contact material performance or advanced termination features.

Frequently Asked Questions (FAQ)

Q: Can OSTTJ147150 be used as a direct replacement for ED950/14?

A: OSTTJ147150 is mechanically and electrically compatible with ED950/14 for applications within the ED950/14 operating temperature range (-30°C to 105°C) and wire gauge range (12-22 AWG). Both parts share identical pitch, position count, and mounting configuration. The expanded specifications of OSTTJ147150 do not create incompatibility; however, the different contact material (brass versus copper) and housing material (brass versus polyamide) represent design variations that may affect performance in specific corrosive or thermal environments.

Q: Can 1-796640-4 be used as a direct replacement for ED950/14?

A: 1-796640-4 is mechanically and electrically compatible with ED950/14. Both parts maintain 14 positions at 0.197" (5.00mm) pitch, 300 V UL rating, 15 A UL rating, and free hanging in-line mounting. The rising cage clamp termination method is functionally equivalent to screw termination for connection purposes. The expanded wire gauge range (12-30 AWG) and enhanced operating temperature range (-40°C to 110°C) provide additional capability. The phosphor bronze contact material and PA66 housing represent material upgrades suitable for demanding applications.

Q: What are the key differences between the three parts?

A: ED950/14 features copper contacts and polyamide housing with a standard screw termination torque of 0.5 Nm. OSTTJ147150 uses brass contacts and brass housing with slightly higher torque (0.56 Nm) and extended temperature range. 1-796640-4 employs phosphor bronze contacts, PA66 nylon housing, rising cage clamp termination, and the highest torque specification (0.79 Nm). All three parts meet UL94 V-0 flammability and ROHS3 compliance requirements.

Q: Are there wire gauge compatibility concerns when substituting?

A: ED950/14 is rated for 12-22 AWG (2.5mm²). OSTTJ147150 and 1-796640-4 both support 12-30 AWG ranges. If the original application uses wire gauges within 12-22 AWG, both substitutes are compatible. If the application requires gauges smaller than 12 AWG or larger than 22 AWG, only OSTTJ147150 or 1-796640-4 can accommodate these requirements.

Q: What is the significance of the contact material differences?

A: ED950/14 uses copper contacts, which provide good electrical conductivity and cost efficiency. OSTTJ147150 uses brass contacts, offering improved corrosion resistance. 1-796640-4 uses phosphor bronze contacts, which provide superior corrosion resistance and mechanical strength. Contact material selection depends on environmental exposure, humidity levels, and long-term reliability requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes, ED950/14, OSTTJ147150, and 1-796640-4 are all ROHS3 compliant. However, 1-796640-4 has affected REACH status, while ED950/14 and OSTTJ147150 have unaffected REACH status. This distinction may be relevant for applications subject to REACH regulatory requirements.

Q: What is the difference between standard screw termination and rising cage clamp termination?

A: Both termination methods provide secure electrical connections. Standard screw termination (ED950/14 and OSTTJ147150) requires manual screw tightening to specified torque. Rising cage clamp termination (1-796640-4) uses a spring-loaded mechanism that automatically adjusts to wire diameter, potentially reducing assembly time and torque specification variability.
