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

Part Overview

The C&K 7105SHCLE is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This part operates in a Mom-Off-Mom (momentary-off-momentary) function with a standard round actuator and PC pin termination. The 7105SHCLE is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7105SHCLE are identified based on the following critical parameters that determine functional compatibility:

• Circuit Configuration: SPDT (required match)
• Switch Function: Mom-Off-Mom (required match)
• Mounting Type: Panel Mount (required match)
• Termination Style: PC Pin (required match)
• Bushing Thread: 1/4-40 (required match)
• Current Rating: Minimum 5A AC/DC (equal or higher acceptable)
• Voltage Rating - AC: Minimum 120V (equal or higher acceptable)
• Voltage Rating - DC: Minimum 28V (equal or higher acceptable)
• Actuator Type: Standard Round (required match)
• Operating Temperature Range: Must encompass -30°C to 85°C

Two substitute parts meet these criteria: the C&K 7105SHCRE (direct manufacturer upgrade) and the Electroswitch A127L21HCQ (cross-manufacturer equivalent). The TE Connectivity MTA106GPC provides functional equivalence with noted compliance differences.

Parameter Comparison

Engineering Selection Recommendations

C&K 7105SHCRE: This is the recommended direct substitute. It maintains identical electrical ratings (5A, 120V AC, 28V DC), mechanical configuration, and operating temperature range as the obsolete 7105SHCLE. The 7105SHCRE is active in production with RoHS compliance, making it the preferred choice for direct replacement in existing designs. REACH status differs (REACH Affected vs. REACH Unaffected), requiring compliance verification for specific applications.

Electroswitch A127L21HCQ: This cross-manufacturer equivalent provides higher current capacity (6A) and extended operating temperature range (-30°C to 90°C). The actuator length is longer (13.97mm vs. 10.67mm), which may require panel cutout verification. This part is suitable for applications requiring enhanced electrical performance and is RoHS compliant. REACH status is vendor-undefined, requiring clarification before use in regulated applications.

TE Connectivity MTA106GPC: This substitute offers functional equivalence with higher AC current rating (6A) but reduced DC current rating (4A). The operating temperature range is narrower (-20°C to 80°C), which does not fully encompass the original specification. RoHS non-compliance and REACH-affected status require careful evaluation for regulatory requirements. This option is suitable only when DC current requirements do not exceed 4A and RoHS compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can the 7105SHCRE directly replace the 7105SHCLE without circuit modifications?

A: Yes. The 7105SHCRE maintains identical electrical ratings, circuit configuration, and mechanical mounting specifications. No circuit modifications are required for direct substitution.

Q: What is the primary difference between the 7105SHCRE and A127L21HCQ?

A: The 7105SHCRE is a C&K product with identical specifications to the original part. The A127L21HCQ is an Electroswitch product with higher current capacity (6A vs. 5A), longer actuator length (13.97mm vs. 10.67mm), and extended temperature range (-30°C to 90°C vs. -30°C to 85°C).

Q: Is the MTA106GPC suitable for all applications requiring the 7105SHCLE?

A: The MTA106GPC is suitable only for applications where DC current does not exceed 4A. The original 7105SHCLE is rated for 5A DC. Additionally, the narrower operating temperature range (-20°C to 80°C) may not meet specifications requiring operation at -30°C. RoHS non-compliance must be evaluated against application requirements.

Q: Does actuator length affect panel mounting compatibility?

A: Actuator length affects the protrusion from the panel surface. The A127L21HCQ has a longer actuator (13.97mm vs. 10.67mm), which may require verification against available panel space and user interface design. The 7105SHCRE and MTA106GPC maintain similar actuator lengths to the original part.

Q: What compliance certifications should I verify before selecting a substitute?

A: Verify RoHS compliance requirements for your application. The 7105SHCRE and A127L21HCQ are RoHS compliant; the MTA106GPC is not. Additionally, confirm REACH compliance status with your supplier, as this affects use in regulated markets.

Q: Are all substitute parts available in the same packaging as the original?

A: The 7105SHCLE packaging is listed as "-" (not specified). The A127L21HCQ and MTA106GPC are supplied in bulk packaging. Confirm packaging requirements with your procurement department before ordering.
