C&K 7101SD9APE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SD9APE is an active-status toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This through-hole, right-angle mounted switch is designed for applications requiring reliable on-on switching functionality with epoxy-sealed terminals. Substitute parts are identified when equivalent electrical ratings, circuit topology, mounting configuration, and environmental specifications align with the original component, enabling direct functional replacement in circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7101SD9APE is determined by the following critical parameters:

Circuit Configuration: SPDT topology required for functional equivalence
Electrical Ratings: Current rating of 0.4VA and voltage rating of 20V AC/DC must be met or exceeded
Switch Function: On-On operation required
Mounting Configuration: Through-hole, right-angle orientation required
Termination Style: PC pin termination required
Operating Temperature: -30°C to 85°C range required
Product Status: Active status preferred for ongoing availability
Compliance: ROHS3 compliance required

The E-Switch 100SP1T1B4M6RE meets all critical substitution criteria, maintaining identical electrical specifications, circuit topology, mounting type, and environmental operating range.

Engineering Selection Recommendations

The E-Switch 100SP1T1B4M6RE is a qualified substitute for the C&K 7101SD9APE based on matching electrical specifications, circuit topology, mounting configuration, and environmental compliance. Both components are active-status products with ROHS3 compliance and identical voltage and current ratings.

Two parameter variations exist between the main part and substitute:

Actuator Length: The E-Switch substitute features a 10.41mm actuator length compared to the C&K original's 12.45mm. This difference may affect panel mounting depth and actuator accessibility in space-constrained applications.
Electrical Life: The E-Switch substitute is rated for 40,000 switching cycles versus the C&K original's 100,000 cycles. This difference impacts component longevity in high-cycle-count applications.

Selection between these parts should be based on specific application requirements regarding actuator length constraints and expected switching cycle frequency over the component's operational lifetime.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B4M6RE directly replace the C&K 7101SD9APE in all applications?

A: The E-Switch substitute maintains electrical equivalence and identical mounting configuration. However, the 2.04mm difference in actuator length and the reduced electrical life rating (40,000 versus 100,000 cycles) must be evaluated against specific application requirements before substitution.

Q: What are the critical parameters that define substitution eligibility for this toggle switch?

A: Substitution eligibility is determined by SPDT circuit configuration, 0.4VA current rating, 20V AC/DC voltage rating, on-on switch function, through-hole right-angle mounting, PC pin termination, -30°C to 85°C operating temperature range, and ROHS3 compliance status.

Q: Are there compliance or certification differences between the main part and substitute?

A: Both components are ROHS3 compliant with EAR99 ECCN classification and identical HTSUS codes. The C&K original is REACH Affected, while the E-Switch substitute is REACH Unaffected. Application requirements regarding REACH compliance should be verified before substitution.

Q: How do the electrical life ratings affect component selection?

A: The C&K 7101SD9APE is rated for 100,000 switching cycles, while the E-Switch 100SP1T1B4M6RE is rated for 40,000 cycles. Applications requiring frequent switching or extended operational life should prioritize the higher-rated component.

Q: What packaging considerations apply to these components?

A: Both components are supplied in bulk packaging. Inventory availability differs: C&K 7101SD9APE has 934 pieces in stock, while E-Switch 100SP1T1B4M6RE has 1574 pieces in stock.
