ED120/12DS Equivalent & Substitute Parts

Part Overview

The ED120/12DS is a 12-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with 0.200" (5.08mm) pitch spacing. This component is classified as Active product status and is RoHS3 compliant. Alternative equivalent parts may be required due to inventory constraints, application-specific performance requirements, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution eligibility for the ED120/12DS is determined by strict alignment with the following core parameters: 12 positions per level, 0.200" (5.08mm) pitch, horizontal with board mating orientation, through-hole mounting, and M3 screw thread. All substitute parts must maintain compatibility with these dimensional and mechanical specifications.

The identified substitute parts meet these core requirements:

OSTTA124163 (On Shore Technology Inc.): Matches all core dimensional parameters. Wire termination uses screw with leaf spring and wire guard. Torque specification differs at 0.4 Nm versus 0.5 Nm on the main part.

1-282841-2 (TE Connectivity AMP Connectors): Matches all core dimensional parameters. Wire termination uses screw with rising cage clamp. Current rating is elevated to 17.5 A. Wire gauge range is broader at 12-30 AWG. Torque specification is 0.79 Nm.

Engineering Selection Recommendations

All three parts maintain Active product status and RoHS3 compliance, confirming ongoing manufacturer support and regulatory alignment.

ED120/12DS and OSTTA124163 are both manufactured by On Shore Technology Inc. and are functionally equivalent with identical core specifications. OSTTA124163 includes interlocking side features and carries higher inventory availability (1127 Pcs versus 786 Pcs). The torque specification difference (0.4 Nm versus 0.5 Nm) reflects minor design variation but does not affect substitution eligibility.

1-282841-2 from TE Connectivity AMP Connectors is a cross-manufacturer substitute that meets all core dimensional requirements. This part offers elevated current capacity (17.5 A versus 15 A) and expanded wire gauge compatibility (12-30 AWG versus 14-22 AWG). However, REACH status is listed as Affected, requiring verification against specific regulatory requirements for your application. Operating temperature specification is not provided for this part.

Frequently Asked Questions (FAQ)

Q: Can OSTTA124163 be used as a direct replacement for ED120/12DS?

A: Yes. Both parts share identical core specifications: 12 positions, 0.200" pitch, horizontal with board orientation, through-hole mounting, M3 screw thread, 15 A current rating, and 300 V voltage rating. Both are manufactured by On Shore Technology Inc. and carry RoHS3 compliance.

Q: What are the key differences between ED120/12DS and 1-282841-2?

A: The primary differences are manufacturer (TE Connectivity versus On Shore Technology), wire termination method (leaf spring with wire guard versus rising cage clamp), current rating (15 A versus 17.5 A), wire gauge range (14-22 AWG versus 12-30 AWG), and REACH status (Unaffected versus Affected). All core dimensional parameters remain identical.

Q: Is 1-282841-2 suitable for applications requiring the original ED120/12DS specifications?

A: Substitution is possible due to matching core dimensional and electrical parameters. However, the rising cage clamp termination method differs from the leaf spring design, and REACH status is Affected. Verify compatibility with your specific application requirements and regulatory obligations before selection.

Q: What determines whether a terminal block can substitute for ED120/12DS?

A: Substitution eligibility is determined by: 12 positions per level, 0.200" (5.08mm) pitch, horizontal with board mating orientation, through-hole mounting type, and M3 screw thread. Electrical ratings (current, voltage) and wire gauge compatibility must also align with application requirements.

Q: Are there packaging or inventory considerations for these substitutes?

A: ED120/12DS has 786 Pcs in stock, OSTTA124163 has 1127 Pcs, and 1-282841-2 has 992 Pcs available. All are supplied in Bulk packaging. Inventory levels may influence selection based on project timeline and volume requirements.
