7103MYCBE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The 7103MYCBE is an active production toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuit configuration with On-Off-On switching function. This panel mount switch is rated for 0.4VA at 20V AC/DC operation and is designed for applications requiring reliable electromechanical switching with sealed terminals. Substitute parts are identified when equivalent electrical ratings, mechanical interfaces, and functional characteristics align with the original specification, enabling direct replacement in compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103MYCBE is determined by strict alignment of the following critical parameters:

Electrical Equivalence: Circuit configuration (SPDT), switch function (On-Off-On), current rating (0.4VA AC/DC), and voltage rating (20V AC/DC) must be identical.

Mechanical Compatibility: Panel mount configuration, panel cutout diameter (6.35mm circular), bushing thread specification (1/4-40), and PC pin termination must match exactly.

Environmental & Compliance: Operating temperature range (-30°C to 85°C), electrical life rating (40,000 cycles), and RoHS3 compliance status must be maintained.

The identified substitute part 100SP3T1B1M2REH from E-Switch meets all these criteria, enabling functional equivalence in panel-mounted switching applications with identical electrical and mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the 7103MYCBE and 100SP3T1B1M2REH are active production components with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts may be based on packaging format (7103MYCBE supplied in bulk; 100SP3T1B1M2REH supplied in tray), inventory availability, or supply chain considerations. The E-Switch 100SP3T1B1M2REH variant features a longer actuator length (10.41mm versus 5.08mm), which may affect panel aesthetics or ergonomic considerations in applications where actuator profile is a design factor, though electrical and mechanical interface compatibility remains unchanged.

Frequently Asked Questions (FAQ)

Q: Can the 100SP3T1B1M2REH directly replace the 7103MYCBE in existing designs?

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC, SPDT On-Off-On), mechanical interfaces (6.35mm panel cutout, 1/4-40 bushing thread, PC pin termination), operating temperature range (-30°C to 85°C), and compliance status (ROHS3). Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between these two parts?

A: The actuator length differs: 7103MYCBE has a 5.08mm actuator, while 100SP3T1B1M2REH has a 10.41mm actuator. This affects the physical profile of the switch lever but does not impact electrical function or panel mounting compatibility.

Q: Are there packaging considerations when substituting?

A: Yes. The 7103MYCBE is supplied in bulk packaging, while the 100SP3T1B1M2REH is supplied in tray packaging. Procurement and handling procedures may differ accordingly.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant and rated for identical operating temperature ranges and electrical life cycles (40,000 cycles).

Q: What parameters must remain identical for substitution to be valid?

A: Circuit configuration (SPDT), switch function (On-Off-On), current and voltage ratings (0.4VA at 20V AC/DC), panel mount interface (6.35mm cutout, 1/4-40 thread), termination style (PC pin), and operating temperature range (-30°C to 85°C) must all match exactly.
