C&K 7105SYZBES Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105SYZBES is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features a mom-off-mom (momentary-off-momentary) function with a satin chrome actuator and operates across a temperature range of -30°C to 85°C. The 7105SYZBES is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105SYZBES is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Actuator type and length (Standard Round, 10.67mm)
• Termination style (Solder Lug)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (40,000 Cycles)

The substitute part 7105SYZBE meets all these criteria while differing only in packaging format (Tray vs. Bulk) and product status (Active vs. Obsolete). This part maintains full electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The 7105SYZBE is the direct functional equivalent to the 7105SYZBES. Both parts are ROHS3 compliant and REACH affected, meeting current regulatory requirements. The primary distinction is product status: the 7105SYZBES is obsolete while the 7105SYZBE is active. For applications currently using the 7105SYZBES, the 7105SYZBE provides continuity of supply with identical electrical performance and mechanical fit. The packaging difference (Tray vs. Bulk) does not affect component functionality or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 7105SYZBE directly replace the 7105SYZBES in existing designs?

A: Yes. The 7105SYZBE is electrically and mechanically identical to the 7105SYZBES. All critical parameters—circuit configuration, voltage and current ratings, mounting dimensions, and operating specifications—are equivalent. The only differences are packaging format and product status.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 7105SYZBES is classified as obsolete, indicating it is no longer in production. The 7105SYZBE is active and currently manufactured. For new designs or ongoing procurement, the 7105SYZBE ensures continued availability and supply chain stability.

Q: Does packaging format affect component selection?

A: Packaging format (Bulk vs. Tray) affects order quantities and handling procedures but does not impact electrical performance or mechanical compatibility. Component functionality remains identical regardless of packaging.

Q: Are both parts compliant with current regulations?

A: Yes. Both the 7105SYZBES and 7105SYZBE are ROHS3 compliant and REACH affected, meeting current environmental and regulatory standards.

Q: What are the critical parameters that must match for substitution?

A: Circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (0.4VA), voltage rating (20V AC/DC), mounting type (Panel Mount), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), actuator specifications, termination style (Solder Lug), and operating temperature range (-30°C to 85°C) must all remain constant for functional equivalence.
