ESLM21200 Equivalent & Substitute Parts

Part Overview

The ESLM21200 is a 21-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with side entry wire connections. This component operates at 300V with a 14.6A current rating and accommodates wire gauges from 14-30 AWG using screw-based rising cage clamp termination. The part is currently active in production with 1139 units in stock. Equivalent parts are identified when they maintain the same functional specifications for pitch, positions, mating orientation, current/voltage ratings, and mounting configuration, enabling direct substitution in applications where component availability or supply chain requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

The ESLM21200 has one identified equivalent part: 2-282837-1 manufactured by TE Connectivity AMP Connectors. Substitution eligibility is determined by the following critical parameters that must match or exceed the main part specifications:

• 21 positions per level (exact match required)
• 0.200" (5.08mm) pitch (exact match required)
• Horizontal with board mating orientation (exact match required)
• Minimum 14.6A current rating (equal or higher acceptable)
• Minimum 300V voltage rating (equal or higher acceptable)
• Through hole mounting configuration (exact match required)
• Screw-based rising cage clamp termination (exact match required)
• Polyamide housing material (exact match required)
• RoHS compliance status (matching compliance required)

The substitute part 2-282837-1 satisfies all critical substitution criteria while maintaining functional equivalence for PCB-mounted wire-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ESLM21200 and 2-282837-1 are active production components with RoHS compliance and MSL Level 1 ratings, qualifying them for equivalent substitution in standard PCB-mounted terminal block applications. The primary distinction between these parts is the wire gauge accommodation range: the ESLM21200 accepts 14-30 AWG while the 2-282837-1 accommodates 16-28 AWG. Applications utilizing wire gauges smaller than 16 AWG or larger than 28 AWG require the ESLM21200. For applications within the 16-28 AWG range, either part provides functional equivalence. Contact material composition differs between the parts (copper alloy versus brass base materials), though both employ tin plating on contacts and nickel plating on clamp and screw components. Selection should be based on wire gauge requirements, supply chain availability, and packaging format preference (ESLM21200 supplied in trays; 2-282837-1 supplied in bulk).

Frequently Asked Questions (FAQ)

Q: Can 2-282837-1 directly replace ESLM21200 in all applications?

A: Direct replacement is possible for applications using wire gauges between 16-28 AWG. Applications requiring accommodation of 14 AWG or 30 AWG wire must use the ESLM21200, as the substitute part's wire gauge range does not extend to these sizes.

Q: What is the significance of the different contact base materials?

A: The ESLM21200 uses copper alloy contacts while 2-282837-1 uses brass contacts. Both are tin-plated for corrosion resistance and electrical performance. Material selection does not affect functional substitution for standard applications, though specific environmental or corrosion resistance requirements may influence part selection.

Q: Are there packaging differences between these parts?

A: Yes. The ESLM21200 is supplied in trays, while 2-282837-1 is supplied in bulk packaging. Procurement and handling procedures may differ accordingly.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry MSL Level 1 ratings. The ESLM21200 is EAR99 classified; 2-282837-1 is also EAR99 classified and REACH affected. Compliance verification should be confirmed for specific regulatory requirements.

Q: What torque specifications apply to each part?

A: The ESLM21200 specifies 0.5 Nm (4.4 Lb-In) screw torque, while 2-282837-1 specifies 0.68 Nm (6 Lb-In). Installation procedures should follow the torque specification of the selected part.
