EDZ950/18 Terminal Block Plug – Equivalent & Substitute Parts

Part Overview

The EDZ950/18 is an 18-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.200" (5.08mm) pitch spacing. This component is designed for free-hanging (in-line) applications requiring screw termination with a rated voltage of 300V and operating temperature range of -30°C to 105°C. The part is currently active in production with 894 units in stock. Alternative equivalent parts may be required due to supply constraints, design revisions, or specific application requirements for enhanced performance parameters such as expanded wire gauge compatibility or improved contact materials.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-796634-8 (TE Connectivity AMP Connectors, Buchanan series) qualifies as a direct equivalent based on the following critical parameters:

• Electrical Compatibility: Both parts maintain 300V UL voltage rating and support the same pitch spacing (0.200"/5.08mm)
• Mechanical Compatibility: Both are 18-position terminal block plugs with female sockets, free-hanging (in-line) mounting configuration
• Termination Method: Both utilize screw-based termination, though the substitute employs rising cage clamp technology
• Environmental Compliance: Both meet UL94 V-0 flammability rating and maintain MSL 1 (unlimited moisture sensitivity level)
• Regulatory Alignment: Both are ROHS compliant and classified under identical HTSUS code 8536.90.4000

The substitute part offers extended wire gauge compatibility (12-30 AWG versus 12-22 AWG) and broader operating temperature range (-40°C to 110°C versus -30°C to 105°C), making it suitable for applications requiring enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

Both the EDZ950/18 and 1-796634-8 are active production components with full regulatory compliance. Selection between these parts should be based on application-specific requirements:

Select EDZ950/18 when:

• Standard wire gauge range (12-22 AWG) meets application requirements
• Operating temperature range of -30°C to 105°C is sufficient
• Lower screw torque specification (0.5 Nm) is preferred for assembly processes
• Copper contact material is specified in design documentation

Select 1-796634-8 when:

• Extended wire gauge compatibility (12-30 AWG) is required
• Broader operating temperature range (-40°C to 110°C) provides design margin
• Rising cage clamp termination technology is preferred for enhanced contact retention
• Higher screw torque specification (0.79 Nm) is acceptable for assembly equipment
• PA66 nylon housing material meets material specification requirements

Both parts maintain identical electrical ratings (300V), mechanical configuration (18-position, 5.08mm pitch), and environmental compliance (UL94 V-0, MSL 1). Physical footprint and mating interface are compatible for direct substitution in free-hanging (in-line) mounting applications.

Frequently Asked Questions (FAQ)

Q: Can 1-796634-8 be used as a direct replacement for EDZ950/18 in existing designs?

A: Yes. Both parts share identical pitch spacing (5.08mm), position count (18), voltage rating (300V), and mounting configuration (free-hanging in-line). The substitute part is mechanically and electrically compatible for direct substitution. Assembly personnel must use the correct screw torque specification (0.79 Nm for the substitute versus 0.5 Nm for the original).

Q: What is the primary difference in wire gauge compatibility?

A: The EDZ950/18 accepts wire gauges from 12-22 AWG (2.5mm²), while 1-796634-8 supports 12-30 AWG (0.05-3mm²). The substitute part accommodates finer wire gauges, making it suitable for applications requiring smaller conductor cross-sections.

Q: Are the contact materials interchangeable?

A: The EDZ950/18 uses copper contacts, while 1-796634-8 uses phosphor bronze contacts. Both materials are suitable for 300V applications. Phosphor bronze offers enhanced spring properties and wear resistance. Material selection should align with design specifications and environmental exposure requirements.

Q: What is the significance of the rising cage clamp termination in 1-796634-8?

A: The rising cage clamp design in the substitute part provides enhanced wire retention and contact pressure compared to standard screw termination. This feature improves connection reliability and reduces the risk of wire displacement during thermal cycling or vibration exposure.

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

A: Both parts are UL94 V-0 rated, RoHS compliant, and classified under HTSUS code 8536.90.4000. The EDZ950/18 is ROHS3 compliant, while 1-796634-8 is RoHS compliant. Both maintain MSL 1 (unlimited) moisture sensitivity level. REACH status differs: EDZ950/18 is REACH unaffected, while 1-796634-8 status is vendor-defined.

Q: What packaging format is available for both parts?

A: Both the EDZ950/18 (894 units in stock) and 1-796634-8 (738 units in stock) are supplied in bulk packaging suitable for manufacturing assembly operations.
