ED205/2DS Terminal Block - Equivalent & Substitute Parts

Part Overview

The ED205/2DS is a 2-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for vertical PCB mounting with 10mm pitch spacing. This active product provides screw-leaf spring wire termination with side interlocking features, rated for 15A at 300V operation across -30°C to 105°C. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and board-level integration requirements are met within the same terminal block category.

Substitute Part Grouping Explanation

Substitution eligibility for the ED205/2DS is determined by the following critical parameters:

Position Count & Pitch: Must maintain 2 positions at 0.394" (10.00mm) spacing for PCB footprint compatibility
Mating Orientation: Must be vertical with board configuration for through-hole mounting
Electrical Ratings: Substitute must meet or exceed 15A current and 300V voltage requirements
Wire Gauge Compatibility: Must accommodate 14-22 AWG wire range or broader
Termination Method: Screw-based termination required for mechanical compatibility
Mounting Interface: Through-hole configuration mandatory for board integration
Regulatory Compliance: ROHS3 compliance required for equivalent status

The substitute part 282852-2 (TE Connectivity AMP Connectors, Buchanan series) meets these criteria with enhanced electrical ratings (17.5A, 600V) and expanded wire gauge acceptance (12-30 AWG), while maintaining identical pitch, position count, and through-hole mounting configuration.

Engineering Selection Recommendations

Both ED205/2DS and 282852-2 are active products with ROHS3 compliance and EAR99 classification, qualifying them for equivalent substitution in applications requiring 2-position, 10mm-pitch terminal blocks with through-hole PCB mounting.

The 282852-2 provides enhanced electrical performance with 17.5A current capacity and 600V voltage rating, exceeding the ED205/2DS specifications. Wire gauge acceptance extends from 12-30 AWG compared to 14-22 AWG, accommodating a broader range of conductor sizes. The rising cage clamp termination mechanism differs from the leaf spring design but maintains M3 screw compatibility and equivalent mechanical interface.

Selection between these parts should be based on application-specific requirements: the ED205/2DS for standard 15A/300V applications, or the 282852-2 when higher electrical ratings or extended wire gauge flexibility are required within the same footprint and mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can 282852-2 directly replace ED205/2DS on existing PCBs?

A: Yes. Both parts maintain identical 2-position configuration, 10mm pitch spacing, M3 screw thread, and through-hole mounting footprint. PCB layout compatibility is preserved.

Q: What is the difference between leaf spring and rising cage clamp termination?

A: Both are screw-based wire termination methods. Leaf spring uses a spring-loaded contact; rising cage clamp uses a mechanical cage mechanism. Both provide equivalent electrical connection and mechanical retention when properly torqued to M3 specifications.

Q: Does the expanded wire gauge range (12-30 AWG) of 282852-2 affect compatibility?

A: No. The 282852-2 accepts the full 14-22 AWG range of the ED205/2DS plus additional gauges. Existing wire sizes remain fully compatible.

Q: Are there operating temperature differences between these parts?

A: The ED205/2DS specifies -30°C to 105°C operation. The 282852-2 does not provide an operating temperature specification in the available data. Verify temperature requirements for your application before selection.

Q: What is the significance of PA versus PA66 housing material?

A: Both are polyamide nylon materials suitable for terminal block applications. PA66 (nylon 6/6) offers slightly enhanced thermal and mechanical properties. Both materials are compatible with the specified operating conditions and electrical ratings.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ED205/2DS and 282852-2 are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).
