C&K 7103SYWME Toggle Switch SPDT 5A 120V Equivalent & Substitute Parts

Part Overview

The C&K 7103SYWME is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The switch features wire wrap termination, epoxy sealed terminals, and operates across a temperature range of -30°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103SYWME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 10.67mm length)
• Termination style (Wire Wrap)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

The C&K 7103SYWSE qualifies as a direct substitute, matching all electrical and mechanical parameters while differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103SYWSE is the direct equivalent for the obsolete 7103SYWME. Both components are ROHS3 compliant and share identical electrical and mechanical specifications. The primary distinction is product status: the 7103SYWSE maintains active production status, ensuring continued availability and supply chain reliability. For applications currently utilizing the 7103SYWME, transition to the 7103SYWSE provides functional continuity without design modification. The substitute part is available in bulk packaging, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7103SYWSE directly replace the 7103SYWME without circuit modification?

A: Yes. Both parts share identical electrical ratings (5A at 120V AC, 28V DC), circuit configuration (SPDT), and mechanical specifications (panel mount, wire wrap termination, 1/4-40 bushing thread). No circuit redesign is required.

Q: What is the primary reason to transition from 7103SYWME to 7103SYWSE?

A: The 7103SYWME is classified as obsolete. The 7103SYWSE maintains active production status, ensuring long-term component availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: The 7103SYWME packaging specification is not defined in available data. The 7103SYWSE is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Do both parts meet the same compliance standards?

A: Both the 7103SYWME and 7103SYWSE are ROHS3 compliant. The 7103SYWME is REACH unaffected; the 7103SYWSE is REACH affected. Verify REACH compliance requirements for your application jurisdiction.

Q: What is the panel cutout requirement for installation?

A: Both parts require a circular panel cutout of 6.35mm diameter with a 1/4-40 bushing thread. Mechanical installation is identical between the two components.
