Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM129200 is determined by the following critical parameters:

• Positions and Pitch: Must maintain 12 positions at 0.200" (5.08mm) spacing to ensure PCB footprint compatibility
• Mating Orientation and Mounting: Must be vertical with board orientation and through-hole mounting for mechanical fit
• Wire Termination Method: Must use screw-based rising cage clamp termination for functional equivalence
• Voltage Rating: Must meet or exceed 300 V specification
• Interlocking Feature: Must include side interlocking for assembly stability

The substitute part 1-282851-2 (TE Connectivity AMP Connectors, Buchanan series) satisfies all critical substitution criteria. This part maintains identical pitch, position count, orientation, mounting type, termination method, voltage rating, and interlocking features. Differences in current rating (17.5 A vs. 10 A), wire gauge range (12-30 AWG vs. 12-28 AWG), housing material, and color do not prevent functional substitution in applications designed for the ELM129200.

Parameter Comparison

Engineering Selection Recommendations

The ELM129200 and 1-282851-2 are functionally equivalent for applications requiring 12-position, 5.08mm-pitch wire-to-board terminal blocks with screw-cage clamp termination. Both parts are active products with current manufacturing status and full RoHS compliance. The substitute part 1-282851-2 provides equal or superior electrical performance, with higher current capacity (17.5 A) and extended wire gauge compatibility (12-30 AWG). Selection between these parts should be based on availability, packaging requirements (tray vs. bulk), and design documentation specifications. No functional degradation occurs when substituting 1-282851-2 for ELM129200 in applications within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can 1-282851-2 be used as a direct replacement for ELM129200 on existing PCBs?

A: Yes. Both parts share identical pitch (5.08mm), position count (12), mounting type (through-hole), and mating orientation (vertical with board). PCB footprints are compatible without modification.

Q: What are the key differences between these parts?

A: The primary differences are housing material (PBT vs. PA66 nylon), color (black vs. green), current rating (10 A vs. 17.5 A), and wire gauge range (12-28 AWG vs. 12-30 AWG). The substitute part exceeds the original specifications in current capacity and wire gauge flexibility.

Q: Are both parts RoHS compliant?

A: Yes. ELM129200 is RoHS Compliant, and 1-282851-2 is ROHS3 Compliant. Both meet environmental compliance requirements.

Q: Does packaging type affect substitution eligibility?

A: Packaging (tray vs. bulk) does not affect electrical or mechanical compatibility. Selection depends on procurement and inventory management requirements.

Q: What is the screw torque specification for both parts?

A: Both parts require 0.79 Nm (7.0 Lb-In) screw torque for proper termination.

Q: Can the wire gauge range difference impact compatibility?

A: No. The substitute part 1-282851-2 accepts 12-30 AWG wire, which encompasses the original 12-28 AWG range. Applications using 12-28 AWG wire are fully compatible with the substitute part.
