EDZ1550/12 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The EDZ1550/12 is a 12-position terminal block plug manufactured by On Shore Technology Inc., designed for screw-terminated connections with 0.150" (3.81mm) pitch spacing. This component is classified as a female socket plug suitable for free-hanging in-line mounting applications. The part is currently active in production with 997 units in stock.

Terminal block plugs require substitute evaluation when original inventory becomes unavailable, when supply chain constraints occur, or when design flexibility permits alternative qualified components. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges to ensure proper circuit function and installation integrity.

Substitute Part Grouping Explanation

Substitution eligibility for the EDZ1550/12 is determined by strict alignment of the following critical parameters:

Position and Pitch Compatibility: The substitute must maintain 12 positions with 0.150" (3.81mm) pitch to ensure mechanical fit within existing connector housings and PCB layouts.

Connector Type and Gender: The substitute must be a plug with female sockets to maintain proper mating with corresponding receptacle components.

Termination Method: The substitute must employ screw-based termination to ensure compatibility with existing wiring practices and installation procedures.

Mounting Configuration: The substitute must support free-hanging in-line mounting to match the original application geometry.

Electrical Ratings: The substitute must meet or exceed the 300 V UL voltage rating and support the wire gauge range of the original specification.

Environmental Compliance: The substitute must maintain ROHS3 compliance and operate within the specified temperature range.

The part 1-284507-2 (TE Connectivity AMP Connectors, Buchanan series) satisfies these substitution criteria while introducing enhanced specifications in certain areas.

Engineering Selection Recommendations

Both the EDZ1550/12 and 1-284507-2 maintain active product status and full ROHS3 compliance, qualifying them for use in applications requiring regulatory adherence. The EDZ1550/12 remains the primary specification when original design validation has been completed against this component.

The 1-284507-2 substitute provides expanded wire gauge accommodation (14-30 AWG versus 16-28 AWG) and an extended operating temperature range (-40°C to 110°C versus -30°C to 105°C). The rising cage clamp termination mechanism in the substitute offers an alternative screw engagement method while maintaining the same 300 V electrical rating.

Selection between these parts should be based on inventory availability, supply chain lead times, and application-specific requirements regarding wire gauge range and temperature extremes. Both components are suitable for equivalent electrical and mechanical function within their specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the 1-284507-2 be used as a direct replacement for the EDZ1550/12?

A: Yes, within the constraints of the specified parameters. Both components share identical pitch (0.150"), position count (12), connector type (plug with female sockets), mounting configuration (free-hanging in-line), and voltage rating (300 V UL). The substitute accommodates a broader wire gauge range and extended temperature limits.

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

A: Both are screw-based termination methods. Rising cage clamp termination uses a spring-loaded mechanism that engages wire during screw tightening, whereas standard screw termination relies on direct screw pressure. Both methods are compatible with the specified wire gauge ranges when properly torqued.

Q: Are there packaging or inventory considerations when switching between these parts?

A: Both parts are supplied in bulk packaging. The EDZ1550/12 currently has 997 units in stock, while the 1-284507-2 has 938 units available. Packaging format compatibility should be confirmed with your procurement process.

Q: Does the substitute support the same wire gauge as the original part?

A: The substitute supports a wider range: 14-30 AWG (0.05-2mm²) compared to the original 16-28 AWG (1.5mm²). Applications using wire gauges within the original specification will function identically with the substitute.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the EDZ1550/12 and 1-284507-2 are ROHS3 compliant, carry MSL rating 1 (unlimited moisture sensitivity), and share the same ECCN (EAR99) and HTSUS classification (8536.90.4000).
