Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SY9CLE are grouped based on strict electrical and mechanical compatibility criteria:

Direct Equivalent (Same Electrical Ratings):

• 7201SY9CRE (C&K): Maintains identical circuit configuration (DPDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), mounting type (Through Hole), actuator specifications (Standard Round, 10.67mm), and termination style (PC Pin). Primary difference is active product status and RoHS compliance.

Similar Substitutes (Matching Core Electrical Parameters with Noted Variations):

• 100DP1T1B2M2QE (E-Switch): Matches DPDT configuration, On-On function, 5A current rating, 120V AC / 28V DC voltage ratings, Through Hole mounting, and PC Pin termination. Actuator length differs at 10.41mm. Electrical life rated at 40,000 cycles versus 100,000 cycles.
• 100DP1T3B4M2RE (E-Switch): Shares DPDT configuration, On-On function, Through Hole mounting, Standard Round actuator, and PC Pin termination. Electrical ratings differ significantly: 0.4VA at 20V AC/DC (reduced from 5A at 120V AC). Actuator length 13.97mm. Electrical life 40,000 cycles.
• A223S1D9CQ (Electroswitch): Matches DPDT configuration, On-On function, Through Hole mounting, Standard Round actuator (10.41mm), and PC Pin termination. Current rating elevated to 6A at 125V AC / 28V DC. Electrical life 60,000 cycles. Operating temperature range -30°C to 90°C.
• A223P32D9CQ (Electroswitch): Matches DPDT configuration, On-On function, Through Hole mounting, and PC Pin termination. Actuator type is Flatted (not Standard Round) with length 11.38mm. Current rating 6A at 125V AC / 28V DC. Electrical life 60,000 cycles.
• A223L21D9CQ (Electroswitch): Matches DPDT configuration, On-On function, Through Hole mounting, Standard Round actuator (13.97mm), and PC Pin termination. Current rating 6A at 125V AC / 28V DC. Electrical life 60,000 cycles.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 7201SY9CRE is the primary direct equivalent, maintaining all electrical and mechanical specifications of the 7201SY9CLE while offering active product status. The 7201SY9CRE is RoHS Compliant and REACH Affected, providing improved regulatory alignment compared to the obsolete 7201SY9CLE.

For Applications Requiring Higher Current Capacity: The A223S1D9CQ, A223P32D9CQ, and A223L21D9CQ from Electroswitch provide 6A current rating at 125V AC, exceeding the 5A specification of the original part. These parts are RoHS Compliant and suitable for designs requiring enhanced current handling. Actuator length variations (10.41mm, 11.38mm, 13.97mm) must be verified against panel cutout and mechanical constraints.

For Low-Voltage Applications: The 100DP1T3B4M2RE is suitable only for applications operating at 20V AC/DC or lower. This part is not interchangeable with the 7201SY9CLE in standard 120V AC circuits due to reduced voltage rating.

For Standard 5A / 120V AC Applications: The 100DP1T1B2M2QE maintains the 5A / 120V AC electrical specification. Electrical life is reduced to 40,000 cycles compared to 100,000 cycles in the original part. This substitution is acceptable for applications with lower cycle count requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7201SY9CRE directly replace the 7201SY9CLE without circuit modification? A: Yes. The 7201SY9CRE maintains identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (DPDT On-On), mounting type (Through Hole), actuator specifications (Standard Round, 10.67mm), and termination style (PC Pin). No circuit modification is required.

Q: What is the primary difference between the 7201SY9CLE and 7201SY9CRE? A: The 7201SY9CRE is an active product with RoHS Compliance and REACH Affected status, whereas the 7201SY9CLE is obsolete and RoHS Non-Compliant. Electrical and mechanical specifications are identical.

Q: Are the Electroswitch A223 series parts compatible with the 7201SY9CLE? A: The A223 series parts share the same DPDT On-On configuration and Through Hole mounting. However, they provide higher current capacity (6A at 125V AC versus 5A at 120V AC) and reduced electrical life (60,000 cycles versus 100,000 cycles). Actuator lengths vary between 10.41mm and 13.97mm. Compatibility depends on circuit voltage requirements and mechanical panel constraints.

Q: What is the significance of the 100DP1T3B4M2RE having a 0.4VA rating instead of 5A? A: The 100DP1T3B4M2RE is rated for low-voltage applications at 20V AC/DC maximum. This part is not suitable for replacement in circuits designed for 120V AC operation. It is listed as a similar substitute only for applications requiring reduced voltage and current specifications.

Q: How do actuator length variations affect substitution? A: Actuator length determines the physical engagement depth with panel-mounted controls. The 7201SY9CLE has a 10.67mm actuator. Substitute parts range from 10.41mm to 13.97mm. Verify that the selected substitute's actuator length is compatible with the panel cutout depth and mechanical assembly constraints of the target application.

Q: What is the impact of reduced electrical life in substitute parts? A: The 7201SY9CLE is rated for 100,000 electrical cycles. E-Switch 100 series parts are rated for 40,000 cycles, and Electroswitch A223 series parts for 60,000 cycles. Select substitutes based on the expected number of switch actuations over the product lifetime. Applications with high cycle counts may require the original specification or the 7201SY9CRE equivalent.

Q: Are all substitute parts RoHS Compliant? A: Yes. All active substitute parts listed (7201SY9CRE, 100DP1T1B2M2QE, 100DP1T3B4M2RE, A223S1D9CQ, A223P32D9CQ, A223L21D9CQ) are RoHS Compliant or ROHS3 Compliant. The original 7201SY9CLE is RoHS Non-Compliant.

Q: Can the A223P32D9CQ with a Flatted actuator replace the 7201SY9CLE with a Standard Round actuator? A: The A223P32D9CQ has a Flatted actuator type versus the Standard Round actuator of the 7201SY9CLE. This affects the mechanical interface with control knobs or levers. Verify that the target application's mechanical assembly is compatible with a Flatted actuator profile before substitution.
