MEC Switches 3ETL9 Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The MEC Switches 3ETL9 is a tactile switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 0.05A at 24VDC. This through-hole mounted component features top actuation with a plunger-type actuator and sealed design for IP67 ingress protection. The 3ETL9 is classified as obsolete, making identification of functionally equivalent active alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3ETL9 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Contact rating (0.05A @ 24VDC)
• Actuator type and orientation (Plunger for Cap, Top Actuated)
• Mounting method (Through Hole)
• Physical outline (10.10mm x 10.10mm)
• Operating force (300gf)
• Switch travel (1.00mm)
• Ingress protection rating (IP67)
• Termination style (PC Pin)
• Mechanical life specification (10,000,000 Cycles)

The 3ETH9 meets all substitution criteria as an active product within the Multimec® 3 series, maintaining identical electrical and mechanical specifications while offering improved operating temperature range and current product status.

Parameter Comparison

Engineering Selection Recommendations

The 3ETH9 is the direct active equivalent for the obsolete 3ETL9. Both components maintain identical electrical performance, mechanical specifications, and physical form factor. The 3ETH9 provides an extended operating temperature range (-40°C to 160°C versus -40°C to 115°C), offering improved thermal performance for applications requiring higher temperature operation. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The 3ETH9's active product status ensures ongoing availability and manufacturer support, making it the appropriate selection for new designs and obsolescence mitigation.

Frequently Asked Questions (FAQ)

Q: Can the 3ETH9 be used as a direct replacement for the 3ETL9 in existing designs?

A: Yes. The 3ETH9 maintains identical circuit configuration, contact rating, actuator type, mounting method, physical dimensions, operating force, switch travel, and ingress protection rating. The extended operating temperature range of the 3ETH9 does not restrict its use in applications designed for the 3ETL9's temperature range.

Q: What is the primary difference between the 3ETL9 and 3ETH9?

A: The 3ETH9 is the active production equivalent with an extended operating temperature range (-40°C to 160°C compared to -40°C to 115°C) and current product status. All other electrical and mechanical parameters are identical.

Q: Are there any packaging or pin configuration differences?

A: No. Both parts use identical through-hole PC pin termination and maintain the same 10.10mm x 10.10mm outline dimensions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 3ETL9 and 3ETH9 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Is the 3ETH9 suitable for sealed or waterproof applications?

A: Yes. The 3ETH9 maintains the IP67 ingress protection rating (dust tight, waterproof) with sealed flux protection features identical to the 3ETL9.
