ESLM21100 Equivalent & Substitute Parts

Part Overview

The ESLM21100 is a 21-position wire-to-board terminal block manufactured by Amphenol PCD, designed for side-entry horizontal mounting with 5.00mm pitch spacing. This component is classified as an active product and serves as a connection interface in PCB applications requiring screw-based wire termination. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling component interchangeability in circuit designs where pin count flexibility or alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 2-282836-1 (TE Connectivity AMP Connectors, Buchanan series) qualifies as an equivalent based on the following alignment of critical parameters:

• Pitch: 0.197" (5.00mm) — identical spacing
• Current Rating: 14.6 A — identical electrical capacity
• Voltage Rating: 300 V — identical electrical capacity
• Mounting Type: Through Hole — identical PCB integration method
• Wire Termination: Screw - Rising Cage Clamp — identical connection mechanism
• Mating Orientation: Horizontal with Board — identical board orientation
• Housing Material: Polyamide (PA66), Nylon 6/6 — identical material composition
• RoHS Compliance: Both parts are RoHS Compliant

The primary difference is the position count: the substitute provides 20 positions versus the main part's 21 positions. This substitution is valid in applications where the circuit design accommodates a 20-position configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the ESLM21100 and 2-282836-1 are active products with RoHS compliance certification, making them suitable for modern electronics manufacturing. The ESLM21100 supports wire gauges from 14 AWG, while the substitute 2-282836-1 begins at 16 AWG. Selection between these parts depends on whether the circuit design requires the full 21-position capacity of the main part or can operate with the 20-position configuration of the substitute. Both parts maintain identical electrical ratings (14.6 A, 300 V) and identical mechanical interfaces (5.00mm pitch, through-hole mounting, screw termination). The choice between manufacturers (Amphenol PCD versus TE Connectivity) should be based on supply chain availability, lead time, and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2-282836-1 substitute directly replace the ESLM21100 in all applications?

A: Direct substitution is possible only in applications designed for 20-position terminal blocks. The ESLM21100 provides 21 positions; the substitute provides 20 positions. PCB layout and circuit design must accommodate this difference.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts are rated for 14.6 A current and 300 V voltage. Both support screw-based wire termination with identical cage clamp mechanisms.

Q: What is the difference in wire gauge compatibility?

A: The ESLM21100 accepts wire gauges from 14-30 AWG. The 2-282836-1 accepts 16-30 AWG. If your application requires 14 or 15 AWG wire termination, only the ESLM21100 is suitable.

Q: Do both parts have the same pitch spacing?

A: Yes. Both parts feature 0.197" (5.00mm) pitch spacing, ensuring identical PCB footprint dimensions for the contact positions that exist on both parts.

Q: Are both parts RoHS compliant?

A: Yes. Both the ESLM21100 and 2-282836-1 are RoHS Compliant, meeting environmental and regulatory requirements for modern electronics manufacturing.

Q: What is the difference in packaging?

A: The ESLM21100 is supplied in Tray packaging, while the 2-282836-1 is supplied in Bulk packaging. This affects handling and storage but does not impact electrical or mechanical performance.
