SWT6-M3GTR Equivalent & Substitute Parts

Part Overview

The SWT6-M3GTR is a tactile switch manufactured by TT Electronics / BI Technologies, designed 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 a 5.00mm actuator height and gull wing termination style.

The SWT6-M3GTR 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

Substitute parts for the SWT6-M3GTR are identified based on functional and mechanical compatibility within the tactile switch category. The primary substitution criteria are:

• Circuit Configuration: SPST-NO topology must be maintained
• Switch Function: Momentary contact (Off-Mom) operation required
• Mounting Type: Surface mount with gull wing termination
• Physical Envelope: 6.00mm x 6.00mm outline and 5.00mm actuator height
• Actuator Orientation: Top actuated design
• Operating Force: 160gf actuation force
• Contact Rating: Minimum 0.05A switching capacity at rated voltage

The FSM4JSMATR meets these core mechanical and functional parameters, enabling direct substitution in applications where the voltage rating differential is acceptable within the circuit design.

Parameter Comparison

Engineering Selection Recommendations

The FSM4JSMATR is an active product from TE Connectivity ALCOSWITCH Switches and represents a viable substitute for the obsolete SWT6-M3GTR. Both components share identical mechanical envelopes, actuator specifications, and circuit topology.

Key considerations for selection:

• Voltage Rating: The FSM4JSMATR is rated for 24VDC versus the SWT6-M3GTR's 12VDC rating. In applications operating at 12VDC or lower, the FSM4JSMATR provides additional voltage margin and is suitable for direct substitution.
• Product Status: The FSM4JSMATR is active and widely available, addressing the obsolescence of the SWT6-M3GTR.
• Compliance: The FSM4JSMATR is ROHS3 compliant, supporting modern regulatory requirements.
• Mechanical Life: The SWT6-M3GTR specifies 500,000 cycles versus 100,000 cycles for the FSM4JSMATR. Applications requiring extended cycle life should account for this difference.
• Temperature Range: The FSM4JSMATR operates across -40°C ~ 85°C, providing broader environmental coverage than the SWT6-M3GTR's -20°C ~ 70°C range.

Frequently Asked Questions (FAQ)

Q: Can the FSM4JSMATR directly replace the SWT6-M3GTR in a 12VDC circuit?

A: Yes. The FSM4JSMATR's 24VDC contact rating is compatible with 12VDC operation. Both components share identical mechanical and functional specifications, including SPST-NO topology, 160gf operating force, 5.00mm actuator height, and 6.00mm x 6.00mm outline. PCB layout and footprint remain unchanged.

Q: What is the impact of the mechanical life difference between these parts?

A: The SWT6-M3GTR specifies 500,000 cycles while the FSM4JSMATR specifies 100,000 cycles. Applications with high-frequency actuation cycles should evaluate whether the FSM4JSMATR's cycle rating meets operational requirements. For typical momentary switch applications with moderate actuation frequency, the FSM4JSMATR is suitable.

Q: Are there packaging differences between these parts?

A: The SWT6-M3GTR packaging is listed as "-" (not specified). The FSM4JSMATR is supplied in Cut Tape (CT) and Digi-Reel® packaging. Verify packaging compatibility with assembly processes and procurement workflows.

Q: Does the FSM4JSMATR meet current regulatory standards?

A: Yes. The FSM4JSMATR is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The SWT6-M3GTR product status is obsolete, making the FSM4JSMATR the preferred choice for new designs and ongoing production.

Q: What is the actuator material difference?

A: The FSM4JSMATR specifies Polyphenylene Sulfide (PPS) as the actuator material. The SWT6-M3GTR actuator material is not specified in available documentation. Both materials are suitable for standard tactile switch applications.
