EDZ1550/3 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The EDZ1550/3 is a 3-position terminal block plug manufactured by On Shore Technology Inc., designed for free-hanging (in-line) applications with 0.150" (3.81mm) pitch spacing. This component features female sockets with screw termination, rated for 300V UL and operating temperatures from -30°C to 105°C. The part is actively produced and ROHS3 compliant, with 1078 units currently in stock.

Substitute parts become necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when application requirements align with parts offering extended operating ranges or enhanced mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EDZ1550/3 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 3-position configuration with 0.150" (3.81mm) pitch spacing (mechanical interchangeability)
• Female socket plug type with screw termination
• Free-hanging (in-line) mounting orientation
• 300V UL voltage rating minimum
• Wire gauge compatibility within the 16-28 AWG range
• Operating temperature range that encompasses or exceeds the application requirement
• ROHS3 compliance and MSL 1 rating

Identified Substitute Parts:

1. OSTTJ0331530 (On Shore Technology Inc.) - Direct manufacturer alternative with identical pitch, position count, and mounting type. Wire gauge range 16-26 AWG overlaps with the main part. Extended operating temperature range (-40°C to 115°C) provides broader environmental compatibility.

2. 284507-3 (TE Connectivity AMP Connectors) - Manufacturer-recommended substitute with matching pitch, position count, and voltage rating. Expanded wire gauge range (14-30 AWG) accommodates broader conductor sizes. Enhanced specifications include current rating (11A UL), improved flammability rating (UL94 V-0), and extended operating temperature (-40°C to 110°C).

Parameter Comparison

Engineering Selection Recommendations

EDZ1550/3 (Primary Part): Select when standard operating conditions (-30°C to 105°C) are sufficient and On Shore Technology Inc. inventory is available. ROHS3 compliance and MSL 1 rating support standard industrial applications.

OSTTJ0331530 (On Shore Alternative): Select as a direct manufacturer substitute when EDZ1550/3 availability is constrained. The extended operating temperature range (-40°C to 115°C) accommodates applications requiring broader environmental tolerance. Wire gauge range 16-26 AWG covers the majority of typical applications within the EDZ1550/3 specification. Higher inventory (1975 units) supports rapid procurement.

284507-3 (TE Connectivity Recommended): Select when applications require enhanced electrical performance (11A current rating), superior flammability characteristics (UL94 V-0), or extended wire gauge compatibility (14-30 AWG). The rising cage clamp termination provides alternative mechanical engagement. Extended operating temperature (-40°C to 110°C) and REACH compliance documentation support regulated environments. Highest inventory availability (5976 units) ensures supply chain continuity.

All three parts maintain ROHS3 compliance, MSL 1 rating, and 300V UL voltage specification, ensuring regulatory and environmental compatibility across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can OSTTJ0331530 directly replace EDZ1550/3 in all applications?

A: OSTTJ0331530 is mechanically and electrically compatible for applications operating within the -40°C to 115°C range and using wire gauges 16-26 AWG. Applications requiring 27-28 AWG conductors must use EDZ1550/3 or 284507-3.

Q: What is the primary difference between EDZ1550/3 and 284507-3?

A: 284507-3 offers expanded wire gauge range (14-30 AWG vs. 16-28 AWG), specified current rating (11A), UL94 V-0 flammability rating, and rising cage clamp termination. EDZ1550/3 uses standard screw termination. Both maintain 300V rating and 3-position 3.81mm pitch configuration.

Q: Are all three parts suitable for low-temperature applications below -30°C?

A: EDZ1550/3 is rated to -30°C minimum. OSTTJ0331530 and 284507-3 are rated to -40°C, making them suitable for extended low-temperature environments. Application requirements determine which part is appropriate.

Q: Does wire gauge compatibility affect substitution decisions?

A: Yes. EDZ1550/3 accommodates 16-28 AWG. OSTTJ0331530 accommodates 16-26 AWG. 284507-3 accommodates 14-30 AWG. Applications using 27-28 AWG conductors cannot use OSTTJ0331530. Applications using 14-15 AWG conductors require 284507-3.

Q: What is the significance of the rising cage clamp termination in 284507-3?

A: Rising cage clamp termination provides an alternative mechanical engagement method compared to standard screw termination. Both methods achieve equivalent electrical connection at 300V. Selection depends on assembly process compatibility and operator preference.

Q: Are all parts available in the same packaging format?

A: All three parts are supplied in bulk packaging. Inventory levels differ: EDZ1550/3 (1078 units), OSTTJ0331530 (1975 units), 284507-3 (5976 units). Procurement timelines may vary based on current stock levels.
