GS01MSAKE(T&R) Equivalent & Substitute Parts
Part Overview
The GS01MSAKE(T&R) is a slide switch SPDT (Single Pole Double Throw) surface mount component manufactured by C&K, rated for 0.4VA at 20V with right-angle mounting configuration. This part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. The GS01MSABE serves as the direct functional equivalent within the GS series product line.

Substitute Part Grouping Explanation
The GS01MSABE is classified as a direct substitute for the GS01MSAKE(T&R) based on the following matching parameters:
- Circuit configuration: SPDT
- Current rating: 0.4VA (AC/DC)
- Voltage ratings: 20V AC and 20V DC
- Mounting type: Surface Mount, Right Angle
- Termination style: Gull Wing
- Switch travel: 1.27mm
- Mechanical and electrical life: 40,000 cycles
- Contact finish: Gold
- Actuator material: Polyetherimide (PEI)
- Series designation: GS
The GS01MSABE differs in contact material composition (copper versus beryllium copper), operating temperature range (-40°C to 85°C versus -30°C to 85°C), and product status (active versus obsolete). These differences do not preclude functional substitution within the specified electrical and mechanical parameters.

Engineering Selection Recommendations
The GS01MSABE is the appropriate selection for applications currently using or specifying the obsolete GS01MSAKE(T&R). The substitute part maintains electrical and mechanical compatibility across all critical parameters including circuit configuration, current and voltage ratings, mounting geometry, and lifecycle specifications.
The GS01MSABE offers the additional advantage of ROHS3 compliance, addressing regulatory requirements for new product designs and manufacturing environments subject to RoHS directives. The extended lower operating temperature limit (-40°C versus -30°C) provides enhanced thermal margin for applications operating in cold environments.
The contact material change from beryllium copper to copper does not affect functional performance within the specified electrical parameters. Both materials achieve the required gold finish and maintain equivalent contact reliability across the 40,000-cycle mechanical and electrical life specifications.
Frequently Asked Questions (FAQ)
Q: Can GS01MSABE directly replace GS01MSAKE(T&R) in existing designs?
A: Yes. The GS01MSABE maintains identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), mounting type (surface mount, right angle), and termination style (gull wing). Mechanical specifications including switch travel (1.27mm) and lifecycle ratings (40,000 cycles) are equivalent.
Q: What is the difference in contact material, and does it affect performance?
A: The GS01MSAKE(T&R) uses beryllium copper contacts while the GS01MSABE uses copper contacts. Both materials are finished with gold plating and perform identically within the specified electrical parameters of 0.4VA at 20V.
Q: Does the GS01MSABE support the same operating temperature range?
A: The GS01MSABE extends the lower temperature limit to -40°C compared to -30°C for the GS01MSAKE(T&R). The upper limit remains 85°C for both parts. Applications operating within -30°C to 85°C experience no temperature-related compatibility issues.
Q: What packaging options are available for the GS01MSABE?
A: The GS01MSABE is supplied in Tape & Reel (TR) packaging format, standard for surface mount component distribution.
Q: Is the GS01MSABE RoHS compliant?
A: Yes. The GS01MSABE is ROHS3 compliant, whereas the obsolete GS01MSAKE(T&R) is RoHS non-compliant. This compliance status is relevant for designs subject to RoHS regulatory requirements.
Q: Are both parts REACH compliant?
A: Both the GS01MSAKE(T&R) and GS01MSABE carry REACH Unaffected status, indicating no REACH substance of concern restrictions apply to either part.
