C&K 7105SY3AV2KE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105SY3AV2KE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. It features panel mount installation with right angle vertical orientation and mom-off-mom switch function. The part is classified as obsolete, making identification of suitable substitute components necessary for ongoing system maintenance and new design implementations where legacy compatibility is not required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105SY3AV2KE is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current rating (0.4VA AC/DC)
• Voltage rating (20V AC/DC)
• Mounting type (Panel Mount, Right Angle, Vertical)
• Actuator type and length (Standard Round, 10.67mm)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)
• Base product number (7105SY)

Allowable Variations:

• Panel cutout dimensions (mechanical interface tolerance)
• Bushing thread specification (mechanical interface tolerance)
• Product status (active vs. obsolete)
• Compliance certifications (RoHS, REACH)

The C&K 7105SY3AV2PE qualifies as a direct substitute based on identical electrical specifications and functional parameters, with mechanical interface variations that remain within acceptable substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105SY3AV2PE is a qualified substitute for the obsolete 7105SY3AV2KE based on complete electrical and functional equivalence. The substitute part maintains active product status, ensuring ongoing availability and supply chain continuity.

Compliance Considerations:

• Both parts meet RoHS compliance requirements
• The substitute part carries active REACH status, whereas the main part is REACH unaffected; this distinction reflects regulatory classification and does not impact functional substitution
• Both parts carry EAR99 ECCN classification

Mechanical Interface Considerations:

• Panel cutout diameter variation (6.50mm to 6.35mm) represents a 0.15mm reduction
• Bushing thread specification differs (M6 x 0.75 to 1/4-40); panel mounting hardware must be verified for compatibility with the substitute part's thread specification
• These mechanical variations require validation against specific panel mounting requirements in the target application

Frequently Asked Questions (FAQ)

Q: Can the 7105SY3AV2PE directly replace the 7105SY3AV2KE in existing designs?

A: Electrical and functional replacement is direct. Mechanical panel mounting compatibility must be verified, specifically the bushing thread specification (M6 x 0.75 vs. 1/4-40) and panel cutout diameter tolerance (6.50mm vs. 6.35mm).

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part maintains active manufacturing status, ensuring continued availability and supply chain support. The obsolete status of the main part indicates it is no longer in production.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and carry EAR99 ECCN classification. The REACH status differs in regulatory classification only and does not affect functional or electrical substitution suitability.

Q: What parameters must remain identical for substitution?

A: Circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (0.4VA AC/DC), voltage rating (20V), mounting type (Panel Mount, Right Angle, Vertical), actuator specifications (Standard Round, 10.67mm), termination style (PC Pin), operating temperature range (-30°C to 85°C), and electrical life (40,000 Cycles) must all remain identical.

Q: Are the panel cutout and bushing thread differences critical?

A: These mechanical interface parameters require validation against the specific panel mounting design. The 0.15mm cutout diameter reduction and thread specification change (metric to imperial) must be confirmed compatible with existing panel hardware and mounting fixtures.
