ELM123200 Terminal Block Equivalent & Substitute Parts

Part Overview

The ELM123200 is a 12-position wire-to-board terminal block manufactured by Amphenol PCD, designed for angled PCB mounting with 0.200" (5.08mm) pitch spacing. This component is classified as Active product status and serves as a standard interconnection solution for industrial and commercial applications requiring screw-based wire termination. Substitute parts are identified based on matching electrical ratings, mechanical compatibility, and functional equivalence within the terminal block category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM123200 are qualified based on the following electrical and mechanical parameters:

Core Compatibility Criteria:

• 12 positions per level
• 0.200" (5.08mm) pitch spacing
• Through-hole PCB mounting
• Screw-based wire termination with rising cage clamp mechanism
• Minimum 300 V voltage rating
• Minimum 10 A current rating
• Wire gauge acceptance range overlap (12-28 AWG minimum)
• Side interlocking feature
• Tin-plated brass contacts
• RoHS compliance status

Identified Substitutes:

• 1-1546074-2 (TE Connectivity AMP Connectors, Buchanan Series)
• 1-282847-2 (TE Connectivity AMP Connectors, Buchanan Series)

Both substitute parts meet or exceed the electrical specifications and mechanical requirements of the ELM123200, with variations in mating angle orientation, current capacity, and housing material composition.

Parameter Comparison

Engineering Selection Recommendations

ELM123200 (Primary Part): Suitable for applications requiring standard angled terminal block configuration with RoHS compliance. Active product status ensures continued availability and supply chain stability.

1-1546074-2 (Substitute): Qualifies as a direct functional substitute with enhanced current capacity (17.5 A vs. 10 A) and extended operating temperature range (-40°C to 105°C). ROHS3 compliance and Buchanan series designation provide alternative sourcing. Housing material composition (PA66 Nylon 6/6) differs from the primary part but maintains mechanical and electrical compatibility. Black color matches the original specification.

1-282847-2 (Substitute): Meets electrical and mechanical requirements with identical current and voltage ratings to 1-1546074-2. ROHS3 compliance and unlimited moisture sensitivity rating ensure environmental robustness. Green housing color provides visual differentiation from the primary part. Operating temperature specification is not provided in available documentation.

All substitute parts maintain the 0.200" (5.08mm) pitch, 12-position configuration, screw-based termination mechanism, and through-hole mounting compatibility required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can 1-1546074-2 or 1-282847-2 be used as direct replacements for ELM123200?

A: Yes. Both parts meet the core electrical specifications (300 V, minimum 10 A current capacity), mechanical configuration (12 positions, 5.08mm pitch, through-hole mounting), and wire termination method (screw-based rising cage clamp). Mating angle orientation differs slightly (35° vs. standard angled), but this does not prevent functional substitution in standard PCB applications.

Q: What are the key differences between the substitute parts?

A: 1-1546074-2 and 1-282847-2 are functionally equivalent with identical electrical ratings and mechanical specifications. Primary differences are housing color (black vs. green) and operating temperature documentation (1-1546074-2 specifies -40°C to 105°C; 1-282847-2 does not specify minimum temperature).

Q: Does the housing material change affect compatibility?

A: The substitute parts use Polyamide (PA66) Nylon 6/6 housing instead of Polybutylene Terephthalate (PBT). Both materials are suitable for terminal block applications and maintain mechanical integrity and electrical insulation properties required for 300 V operation.

Q: Are there wire gauge compatibility considerations?

A: The ELM123200 accepts 12-28 AWG wire. Substitute parts accept 12-30 AWG, providing expanded compatibility with finer gauge conductors. This represents an enhancement rather than a limitation.

Q: What is the significance of ROHS3 compliance on substitute parts?

A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive 3, confirming restriction of specified hazardous materials. This meets or exceeds the RoHS compliance requirement of the primary part.

Q: Can packaging differences affect substitution decisions?

A: The primary part is supplied in Tray packaging; substitute parts are supplied in Bulk packaging. This affects logistics and handling but does not impact electrical or mechanical performance. Packaging selection should be based on assembly process requirements and inventory management practices.
