C&K 7101SYWME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SYWME is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features epoxy-sealed terminals, wire wrap termination, and operates across a temperature range of -30°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101SYWME are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for direct substitution:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Panel Mount
• Termination style: Wire Wrap
• Bushing thread: 1/4-40
• Current rating: Equal to or greater than 5A
• Voltage ratings: Equal to or greater than 120V AC and 28V DC
• Actuator type: Standard Round
• Features: Epoxy Sealed Terminals

Substitute parts are grouped into two categories: direct manufacturer equivalents (same manufacturer, active product status) and similar cross-manufacturer alternatives (different manufacturer, compatible electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

C&K 7101SYWSE is the primary direct equivalent for the obsolete 7101SYWME. Both parts share identical electrical ratings, mechanical dimensions, and operational characteristics. The 7101SYWSE maintains active product status with current manufacturing support, ROHS3 compliance, and equivalent electrical life specifications. This part is recommended for direct replacement in existing designs.

Electroswitch A123S1YWQ serves as a cross-manufacturer alternative when C&K 7101SYWSE availability is constrained. The A123S1YWQ exceeds the electrical requirements of the original part with 6A current rating and 125V AC rating, providing operational margin. The actuator length differs by 0.26mm and electrical life is rated at 60,000 cycles versus 100,000 cycles on the original specification. This part is suitable for applications where higher electrical ratings provide design flexibility, though the reduced electrical life cycle count should be evaluated against application duty cycles.

Frequently Asked Questions (FAQ)

Q: Can the 7101SYWSE directly replace the obsolete 7101SYWME?

A: Yes. The 7101SYWSE is a direct equivalent with identical electrical ratings (5A, 120V AC, 28V DC), mechanical configuration (panel mount, 1/4-40 bushing thread, 6.35mm circular cutout), and operational characteristics (SPDT On-On, 100,000 cycle life, epoxy sealed terminals). No circuit modifications are required.

Q: What are the key differences between the 7101SYWSE and A123S1YWQ?

A: The primary differences are manufacturer (C&K versus Electroswitch), current rating (5A versus 6A), AC voltage rating (120V versus 125V), actuator length (10.67mm versus 10.41mm), and electrical life (100,000 versus 60,000 cycles). Both maintain SPDT On-On configuration, 28V DC rating, wire wrap termination, and 1/4-40 bushing thread compatibility.

Q: Is the A123S1YWQ suitable for applications requiring 100,000 cycle electrical life?

A: The A123S1YWQ is rated for 60,000 electrical cycles. Applications requiring 100,000 cycle life should use the 7101SYWSE or 7101SYWME. The A123S1YWQ is appropriate for applications with lower duty cycle requirements.

Q: Are there panel cutout dimension differences between substitute parts?

A: The 7101SYWME and 7101SYWSE both specify circular 6.35mm diameter panel cutouts with 1/4-40 bushing threads. The A123S1YWQ does not specify panel cutout dimensions in available documentation but maintains the same 1/4-40 bushing thread standard, indicating mechanical compatibility with standard panel mounting hardware.

Q: What compliance certifications apply to each part?

A: The 7101SYWME carries ROHS3 compliance. The 7101SYWSE and A123S1YWQ both carry RoHS compliance. All three parts are classified under ECCN EAR99 and HTSUS 8536.50.9065.
