ESTM02400 Equivalent & Substitute Parts

Part Overview

The ESTM02400 is a 2-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with side entry wire connections. This component operates at 24 A and 300 V, accommodating wire gauges from 11-30 AWG with screw-based rising cage clamp termination. The part is currently active in production and RoHS compliant, making it suitable for industrial and commercial applications requiring reliable wire-to-board connections.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and functional characteristics align with the main part's specifications, enabling component interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

The ESTM02400 and its identified substitute (282861-2) share critical electrical and mechanical parameters that establish substitution eligibility. Both components maintain identical pitch spacing (0.300"/7.62mm), position count (2 positions), mating orientation (horizontal with board), current capacity (24 A), voltage rating (300 V), mounting method (through hole), termination style (screw-based rising cage clamp), and side interlocking features. Both utilize polyamide housing material and are RoHS compliant.

Substitution is valid based on these aligned parameters: equivalent electrical performance (24 A/300 V), compatible mechanical form factor (7.62mm pitch, 2-position configuration), identical mounting approach (through-hole PCB), and matching termination technology (screw rising cage clamp).

Parameter Comparison

Engineering Selection Recommendations

Both the ESTM02400 and 282861-2 are active production components with RoHS compliance and MSL Level 1 ratings, establishing equivalent regulatory and environmental qualification status. Selection between these parts should be based on availability, packaging format (ESTM02400 supplied in trays; 282861-2 supplied in bulk), and wire gauge requirements. The ESTM02400 accommodates wire gauges from 11-30 AWG, while the 282861-2 supports 12-30 AWG, making the ESTM02400 suitable for applications requiring smaller gauge wire termination. Both components meet identical electrical performance criteria and mechanical compatibility requirements for direct substitution in 2-position, 7.62mm pitch terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 282861-2 directly replace the ESTM02400 in existing designs?

A: Yes, the 282861-2 is a direct substitute for the ESTM02400 in applications where wire gauge requirements fall within the 12-30 AWG range. Both components share identical pitch (7.62mm), position count (2), current rating (24 A), voltage rating (300 V), mounting type (through hole), and termination method (screw rising cage clamp). If your design requires wire gauges smaller than 12 AWG, the ESTM02400 remains the appropriate choice.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Amphenol PCD vs. TE Connectivity), wire gauge range (ESTM02400: 11-30 AWG; 282861-2: 12-30 AWG), housing color (black vs. green), contact material composition (copper alloy vs. brass), screw torque specification (0.5 Nm vs. 0.79 Nm), and packaging format (tray vs. bulk). All electrical and mechanical parameters remain equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both the ESTM02400 and 282861-2 are RoHS compliant. The 282861-2 is additionally REACH affected.

Q: What packaging options are available?

A: The ESTM02400 is supplied in trays with 825 pieces in stock. The 282861-2 is supplied in bulk packaging with 5021 pieces in stock.

Q: Which part should I select for new designs?

A: Selection depends on wire gauge requirements and availability. For applications using wire gauges 11 AWG and smaller, specify the ESTM02400. For applications using wire gauges 12-30 AWG, either part is suitable. Verify component availability and lead times with your supplier before finalizing design specifications.
