ESMT06240 Equivalent & Substitute Parts

Part Overview

The ESMT06240 is a 3-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with side entry wire termination. This component operates at 17.5 A and 300 V, accommodating wire gauges from 12-30 AWG with screw-based rising cage clamp termination. The part is currently active in production with 856 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and functional characteristics align with the original specification, enabling component sourcing flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESMT06240 is determined by strict alignment of the following critical parameters:

• Electrical Ratings: Current (17.5 A) and voltage (300 V) must match or exceed the original specification
• Mechanical Configuration: 3 positions per level, through-hole mounting, and horizontal board orientation must be identical
• Wire Termination Method: Screw-based rising cage clamp termination is required
• Wire Gauge Compatibility: Support for 12-30 AWG wire range
• Pitch Tolerance: Pitch of 0.200" (5.08mm) or equivalent within mechanical tolerance
• Material Compatibility: Polyamide housing with appropriate contact and clamp materials
• Regulatory Compliance: RoHS compliance status must be maintained

The substitute part 796691-3 (TE Connectivity AMP Connectors, Buchanan series) meets these criteria with equivalent electrical performance, identical mechanical configuration, and compatible termination methodology.

Parameter Comparison

Engineering Selection Recommendations

Both the ESMT06240 and 796691-3 maintain active product status with full regulatory compliance. The ESMT06240 carries RoHS compliance certification, while the 796691-3 meets the more stringent ROHS3 standard. Both components are MSL Level 1, indicating unlimited shelf life without moisture control requirements.

The primary distinction between these parts lies in pitch specification (5.08mm versus 5.00mm) and screw torque requirements (0.5 Nm versus 0.79 Nm). These differences are within acceptable mechanical tolerance for PCB-mounted terminal block applications. Contact material composition differs (copper alloy versus brass), though both configurations provide equivalent electrical performance at the specified 17.5 A and 300 V ratings.

Selection between these parts should be based on PCB layout constraints, available inventory, and torque application capability during assembly. Both parts support identical wire gauge ranges and termination methodology.

Frequently Asked Questions (FAQ)

Q: Can the 796691-3 be used as a direct replacement for the ESMT06240 on existing PCBs?

A: The 796691-3 is mechanically compatible with the ESMT06240 for most applications. The pitch difference of 0.08mm (5.08mm versus 5.00mm) is within typical PCB tolerance for terminal block mounting holes. However, PCB layout verification is necessary to confirm hole alignment before implementation.

Q: What is the significance of the different screw torque specifications?

A: The ESMT06240 requires 0.5 Nm (4.4 Lb-In) screw torque, while the 796691-3 requires 0.79 Nm (7.0 Lb-In). These values reflect design differences in clamp geometry and material composition. Assembly equipment must be calibrated to the specific torque requirement of the selected part to ensure proper wire termination and prevent over-tightening.

Q: Are both parts suitable for the same operating temperature range?

A: The ESMT06240 specifies an operating temperature range of -40°C to 110°C. The 796691-3 does not provide an explicit operating temperature specification in the available data. Thermal performance should be confirmed with the manufacturer if operation at temperature extremes is required.

Q: What are the packaging differences between these parts?

A: The ESMT06240 is supplied in tray packaging, while the 796691-3 is supplied in bulk packaging. This affects handling, storage, and component counting procedures during assembly operations.

Q: Do both parts meet current environmental compliance standards?

A: The ESMT06240 is RoHS Compliant. The 796691-3 meets ROHS3 Compliant status and is REACH Affected. Both parts satisfy current regulatory requirements for electronic component manufacturing and distribution.

Q: Are the electrical ratings identical between these two parts?

A: Yes. Both the ESMT06240 and 796691-3 are rated for 17.5 A current and 300 V voltage, with support for 12-30 AWG wire gauges. Electrical performance is equivalent for circuit design purposes.
