ESTM02300 Equivalent & Substitute Parts

Part Overview

The ESTM02300 is a 2-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with side entry wire termination. This component is classified as Active product status and is RoHS compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this terminal block category.

Key Parameters

Substitute Part Grouping Explanation

The ESTM02300 accepts 282861-2 as a substitute based on the following critical parameters:

• Both components maintain 2 positions per level
• Both support 24 A current and 300 V voltage ratings
• Both feature horizontal with board mating orientation
• Both use screw-based rising cage clamp termination with side entry
• Both are through-hole mounted on PCB
• Both use polyamide (PA66) housing material
• Both are RoHS compliant with MSL 1 rating
• Pitch tolerance: 0.295" (7.50mm) versus 0.300" (7.62mm) represents a 0.05mm difference within acceptable mechanical spacing for this terminal block category
• Wire gauge compatibility: 11-30 AWG (main part) versus 12-30 AWG (substitute) maintains overlap across the 12-30 AWG range

Parameter Comparison

Engineering Selection Recommendations

Both the ESTM02300 and 282861-2 are Active product status components with RoHS compliance and MSL 1 ratings, qualifying them for equivalent use in applications requiring 2-position, 24 A, 300 V terminal block functionality. The pitch difference of 0.05mm (7.50mm versus 7.62mm) falls within standard PCB layout tolerances for this terminal block class. Wire gauge overlap at 12-30 AWG ensures compatibility for the majority of wire termination applications. Contact material composition differs (copper alloy versus brass), though both are tin-plated for equivalent electrical performance. Selection between these parts should be based on PCB layout constraints, packaging availability, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 282861-2 be used as a direct replacement for ESTM02300 on existing PCBs?

A: The 0.05mm pitch difference (7.50mm versus 7.62mm) requires PCB layout verification. If the PCB is designed specifically for 7.50mm pitch, the 7.62mm substitute may not align with existing through-hole positions. New PCB designs can accommodate either pitch.

Q: What is the significance of the wire gauge difference (11-30 AWG versus 12-30 AWG)?

A: The ESTM02300 accepts 11 AWG wire, while the 282861-2 minimum is 12 AWG. Applications using 11 AWG wire must use the ESTM02300. For 12-30 AWG applications, both parts are compatible.

Q: Are the contact materials interchangeable from an electrical standpoint?

A: Both copper alloy and brass contacts are tin-plated and rated for identical voltage and current specifications. Electrical performance is equivalent for the specified 24 A and 300 V ratings.

Q: What packaging differences exist between these parts?

A: ESTM02300 is supplied in Tray packaging with 1118 pieces in stock. The 282861-2 is supplied in Bulk packaging with 5021 pieces available. Packaging selection depends on assembly process requirements and inventory management.

Q: Is operating temperature specified for both parts?

A: The ESTM02300 specifies -40°C to 110°C operating range. Operating temperature is not specified for the 282861-2 in the provided data. Applications with defined temperature requirements should reference the ESTM02300 specification or request complete thermal data for the 282861-2.
