OSTV4020180 Equivalent & Substitute Parts

Part Overview

The OSTV4020180 is a 2-circuit barrier block connector manufactured by On-Shore Technology, designed for chassis and panel mounting applications. This connector features enclosed barrier protection, screw termination on top, and closed termination on the bottom. The part is currently active in production with 814 units in stock.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters, including circuit count, voltage rating, current capacity, wire gauge compatibility, and termination method. Alternative models may be required due to inventory constraints, lead time considerations, or specific mounting configuration needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the OSTV4020180 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Voltage rating must equal or exceed 600V
• Current rating must support the application requirements
• Wire gauge acceptance range must accommodate 6-22 AWG conductors

Mechanical Compatibility Requirements:

• Terminal block type must be barrier block
• Number of circuits must equal 2
• Number of wire entries must equal 4
• Top termination must be screw-based
• Bottom termination must be closed
• Barrier type must be enclosed

Regulatory & Material Requirements:

• Material flammability rating must meet UL94 V-0
• RoHS3 compliance required
• REACH unaffected status required

The substitute part 071022000 (Curtis Industries) meets these criteria with equivalent circuit configuration, voltage rating, termination method, and regulatory compliance. Differences in current rating options, wire gauge range, mounting type, and insulation material do not preclude substitution when the application requirements fall within the overlapping specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTV4020180 and 071022000 are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component applications.

The OSTV4020180 provides a fixed 65A current rating with wire gauge acceptance from 6-22 AWG and chassis/panel mounting configuration. The 071022000 offers dual current rating options (50A and 86A) with expanded wire gauge range (1-22 AWG) and channel/DIN rail/track mounting options.

Selection between these parts should be based on the specific mounting configuration required by the application and the current rating that matches the circuit design. Both components satisfy the core functional requirements of a 2-circuit, 600V barrier block connector with enclosed protection and screw termination.

Frequently Asked Questions (FAQ)

Q: Can the 071022000 directly replace the OSTV4020180 in all applications?

A: Substitution is valid when the application current requirements fall within the 071022000 current rating options and the mounting configuration is compatible with channel, DIN rail, or track mounting. The OSTV4020180 is optimized for chassis and panel mounting, while the 071022000 supports rail-based mounting. Verify mounting compatibility before substitution.

Q: What are the key electrical parameters that must match for barrier block substitution?

A: The voltage rating (600V), circuit count (2), wire entry count (4), and termination method (screw top, closed bottom) must remain constant. Current rating and wire gauge range may vary provided the application requirements are satisfied by the substitute part's specifications.

Q: Are there differences in insulation material between these parts?

A: Yes. The OSTV4020180 uses polyamide (PA) nylon with glass filling, while the 071022000 uses polybutylene terephthalate (PBT) polyester. Both materials meet UL94 V-0 flammability requirements. Material selection should be verified against specific environmental and chemical exposure requirements of the application.

Q: Do both parts meet the same regulatory standards?

A: Both the OSTV4020180 and 071022000 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component distribution and use in regulated markets.

Q: What is the significance of the wire gauge range difference?

A: The OSTV4020180 accepts 6-22 AWG wire, while the 071022000 accepts 1-22 AWG wire. The 071022000 supports larger diameter conductors (1-5 AWG range). Verify that the substitute part's wire gauge range accommodates the conductor sizes specified in your circuit design.
