SWT6-M2BTR Equivalent & Substitute Parts

Part Overview

The SWT6-M2BTR 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 a 4.30mm actuator height and 260gf operating force. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives from active manufacturers for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SWT6-M2BTR is determined by the following critical parameters:

Electrical Compatibility: Circuit configuration (SPST-NO), contact rating (0.05A minimum), and voltage rating (12VDC minimum) must be maintained or exceeded.

Mechanical Compatibility: Surface mount mounting type, 6.00mm x 6.00mm outline, 4.30mm actuator height, top actuated orientation, and gull wing termination style must match exactly to ensure PCB footprint compatibility.

Operational Characteristics: Operating force, operating temperature range, and mechanical life cycle rating determine functional equivalence for specific applications.

Regulatory Compliance: Moisture sensitivity level MSL 1 and REACH/RoHS status ensure compatibility with manufacturing and environmental requirements.

The substitute parts identified below satisfy these core parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Direct Mechanical and Electrical Equivalents (Preferred):

TL3301NF260QG from E-Switch provides the closest functional match to the SWT6-M2BTR. This part maintains identical mechanical dimensions, actuator height, operating force (260gf), operating temperature range (-20°C ~ 70°C), and electrical specifications (0.05A @ 12VDC). The TL3301NF260QG is active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Alternative Mechanical Equivalents with Reduced Operating Force:

TL3301NF160QG-KR and TL3301NF160RG from E-Switch offer identical mechanical compatibility and electrical ratings but with reduced operating force (160gf). These parts are suitable for applications where lower actuation force is acceptable. Both are active products with ROHS3 compliance and high inventory availability (267,888 and 875 units respectively).

Extended Temperature Range Alternative:

LL3301NF065QG from E-Switch provides extended operating temperature range (-30°C ~ 85°C) with identical mechanical compatibility. This part features significantly reduced operating force (65gf) and is suitable for temperature-sensitive applications where lower actuation force is compatible with circuit requirements.

Voltage-Rated Alternative:

FSM2JSMATR from TE Connectivity ALCOSWITCH Switches is rated for 0.05A @ 24VDC, providing higher voltage margin. This part maintains all mechanical specifications and is suitable for applications operating at elevated voltage levels. The extended operating temperature range (-35°C ~ 85°C) offers thermal flexibility.

All substitute parts maintain MSL 1 classification, REACH compliance, and surface mount gull wing termination, ensuring manufacturing process compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can TL3301NF160QG-KR be used as a direct replacement for SWT6-M2BTR?

A: TL3301NF160QG-KR is mechanically and electrically compatible with SWT6-M2BTR. Both parts share identical outline dimensions (6.00mm x 6.00mm), actuator height (4.30mm), mounting type (surface mount), and electrical rating (0.05A @ 12VDC). The primary difference is operating force: TL3301NF160QG-KR operates at 160gf versus 260gf for SWT6-M2BTR. This substitution is valid when the circuit design accommodates the lower actuation force.

Q: What is the difference between TL3301NF160QG-KR and TL3301NF160RG?

A: Both parts are E-Switch TL3301 series switches with identical electrical and mechanical specifications, including 160gf operating force, 0.05A @ 12VDC rating, and 6.00mm x 6.00mm outline. The primary distinction is packaging: TL3301NF160QG-KR and TL3301NF160RG differ in tape and reel configuration. Inventory availability also differs (267,888 units for QG-KR versus 875 units for RG).

Q: Why does TL3301NF260QG have lower mechanical life (100,000 cycles) compared to SWT6-M2BTR (500,000 cycles)?

A: Mechanical life specifications are determined by component design and manufacturing processes specific to each manufacturer. The TL3301NF260QG is rated for 100,000 cycles, which is the specified operational life for this component. Application requirements should be evaluated against this specification to determine suitability.

Q: Is FSM2JSMATR compatible with 12VDC circuits?

A: FSM2JSMATR is rated for 0.05A @ 24VDC. While the contact rating exceeds 12VDC requirements, this part is suitable for 12VDC operation. The higher voltage rating provides margin but does not prevent operation at lower voltages. All other mechanical specifications (6.00mm x 6.00mm outline, 4.30mm actuator height, surface mount, gull wing termination) are identical to SWT6-M2BTR.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 classification indicates unlimited shelf life without moisture control requirements. Both the original SWT6-M2BTR and all substitute parts carry MSL 1 rating, eliminating moisture sensitivity considerations during storage and handling.

Q: Are all substitute parts RoHS compliant?

A: E-Switch parts (TL3301NF160QG-KR, TL3301NF160RG, TL3301NF260QG, LL3301NF065QG) are ROHS3 compliant. FSM2JSMATR RoHS status is not specified in available documentation. For applications requiring RoHS certification, E-Switch alternatives are recommended.
