SWT6-M2GTR Equivalent & Substitute Parts

Part Overview

The SWT6-M2GTR is a tactile switch manufactured by TT Electronics/BI, configured as a SPST-NO (Single Pole Single Throw - Normally Open) momentary contact switch rated for 0.05A at 12VDC. This surface mount component features a 6.00mm x 6.00mm outline with top actuation and gull wing termination, designed for applications requiring reliable tactile feedback with 500,000 mechanical cycles.

The SWT6-M2GTR is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for systems utilizing this switch.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SWT6-M2GTR is based on the following critical parameters that must align between the main part and substitute candidates:

Circuit configuration (SPST-NO) and switch function (momentary contact) establish the fundamental electrical behavior required for the application. Surface mount mounting type and gull wing termination ensure mechanical and electrical compatibility with existing PCB designs. The 6.00mm x 6.00mm outline dimension is a critical constraint for board layout compatibility.

Operating force (160gf) and actuator orientation (top actuated) define the tactile response and user interface characteristics. Contact rating and voltage specifications determine electrical load capacity. Moisture sensitivity level (MSL 1) indicates compatibility with standard storage and handling conditions.

The FSM4JSMATR from TE Connectivity ALCOSWITCH Switches qualifies as a substitute based on matching circuit configuration (SPST-NO), switch function (momentary), mounting type (surface mount), outline dimensions (6.00mm x 6.00mm), actuator orientation (top actuated), termination style (gull wing), operating force (160gf), and moisture sensitivity level (MSL 1). The substitute maintains functional and mechanical compatibility despite differences in voltage rating, actuator height, operating temperature range, and mechanical life cycle specifications.

Parameter Comparison

Engineering Selection Recommendations

The FSM4JSMATR is an active product from TE Connectivity ALCOSWITCH Switches and is available in high volume (950,200 pieces in stock). This substitute maintains mechanical and electrical compatibility with the obsolete SWT6-M2GTR through matching circuit topology, mounting configuration, and physical outline.

The FSM4JSMATR is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts share MSL 1 classification and EAR99 export control status.

Design considerations for substitution include the 0.70mm increase in actuator height (5.00mm versus 4.30mm), which may require verification of clearance in applications with height constraints. The substitute part supports a higher voltage rating (24VDC versus 12VDC), providing additional margin in higher-voltage applications. The extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) of the FSM4JSMATR accommodates broader environmental conditions.

The mechanical life specification of the FSM4JSMATR (100,000 cycles) is lower than the original part (500,000 cycles). Applications requiring extended cycle life should evaluate this difference against actual usage patterns and system reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can the FSM4JSMATR directly replace the SWT6-M2GTR in existing designs?

A: The FSM4JSMATR maintains the same circuit configuration (SPST-NO), mounting type (surface mount), outline dimensions (6.00mm x 6.00mm), and termination style (gull wing) as the SWT6-M2GTR. Physical board layout compatibility is preserved. The increased actuator height (5.00mm versus 4.30mm) must be verified against enclosure or overlay clearance requirements specific to your application.

Q: What are the voltage rating differences between these parts?

A: The SWT6-M2GTR is rated for 0.05A at 12VDC, while the FSM4JSMATR is rated for 0.05A at 24VDC. The higher voltage rating of the substitute part does not restrict its use in 12VDC applications; it indicates the maximum voltage the switch can safely interrupt. Both parts are suitable for 12VDC circuits.

Q: How do the mechanical life specifications compare?

A: The SWT6-M2GTR specifies 500,000 mechanical cycles, while the FSM4JSMATR specifies 100,000 cycles. For applications with high actuation frequency or extended operational life requirements, this difference should be evaluated against actual usage patterns to determine if the substitute meets reliability objectives.

Q: Are there compliance or certification differences?

A: The FSM4JSMATR is RoHS3 compliant and active in production. The SWT6-M2GTR is obsolete. Both parts are REACH unaffected and carry EAR99 export classification. The active status and current compliance certifications of the FSM4JSMATR support ongoing design and manufacturing requirements.

Q: What is the operating temperature range difference?

A: The SWT6-M2GTR operates from -20°C to 70°C, while the FSM4JSMATR operates from -40°C to 85°C. The extended range of the substitute part provides additional margin for applications in extreme temperature environments.

Q: Are packaging options different between these parts?

A: The FSM4JSMATR is available in Cut Tape (CT) and Digi-Reel packaging options. Packaging selection should align with your procurement and assembly process requirements.
