C&K 7203SPD9CME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203SPD9CME is a through-hole mounted toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features an anti-rotation actuator with brass chrome-plated construction and epoxy sealed terminals. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203SPD9CME is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Current rating: 5A (AC/DC)
• Voltage rating - AC: 120V minimum
• Voltage rating - DC: 28V
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C minimum

Allowable Variations:

• Actuator type (anti-rotation vs. standard round)
• Actuator length (within mechanical compatibility range)
• Product status (active substitutes preferred for obsolete parts)
• RoHS compliance status
• Electrical life (equal or greater)
• Ingress protection rating (additional protection acceptable)

Two substitute parts meet these criteria: the C&K 7203SPD9CSE (direct manufacturer upgrade) and the Grayhill Inc. 34BWDP31B4M2QT (cross-manufacturer alternative).

Parameter Comparison

Engineering Selection Recommendations

C&K 7203SPD9CSE (Direct Manufacturer Substitute): This part represents the active production equivalent within the C&K 7000 series. It maintains identical electrical specifications, actuator geometry, and mechanical interface with the obsolete 7203SPD9CME. The primary distinction is product status (active vs. obsolete) and RoHS compliance. Selection of this part is appropriate for designs requiring direct form-fit-function replacement with current manufacturing support and compliance documentation.

Grayhill Inc. 34BWDP31B4M2QT (Cross-Manufacturer Alternative): This part satisfies all mandatory electrical and mechanical parameters while offering enhanced specifications in electrical life (50,000 cycles vs. 40,000) and ingress protection (IP67 rating). The actuator type differs (standard round vs. anti-rotation) and actuator length increases by 0.15mm. AC voltage rating is 125V versus 120V. Selection of this part is appropriate for applications where enhanced environmental protection or extended cycle life provides design benefit, provided mechanical envelope constraints are verified.

Frequently Asked Questions (FAQ)

Q: Can the 7203SPD9CSE directly replace the 7203SPD9CME without circuit modification? A: Yes. The 7203SPD9CSE maintains identical DPDT circuit configuration, current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), and PC pin termination. No circuit modification is required.

Q: What is the significance of the actuator type difference between the main part and the Grayhill substitute? A: The 7203SPD9CME features an anti-rotation actuator, while the 34BWDP31B4M2QT uses a standard round actuator. Anti-rotation design prevents unintended rotation during installation. The standard round actuator does not provide this constraint. Mechanical panel design must accommodate this difference.

Q: Does the 0.15mm actuator length difference between substitutes affect mechanical compatibility? A: The 7203SPD9CME and 7203SPD9CSE both specify 12.45mm actuator length. The Grayhill 34BWDP31B4M2QT specifies 12.60mm. This 0.15mm difference must be evaluated against panel cutout and mechanical envelope constraints in the specific application.

Q: Why is RoHS compliance status different between the main part and substitutes? A: The 7203SPD9CME is classified as RoHS non-compliant, reflecting its obsolete status and manufacturing date. The 7203SPD9CSE and 34BWDP31B4M2QT are both RoHS compliant, meeting current regulatory requirements for new production designs.

Q: What does the IP67 rating on the Grayhill part provide? A: IP67 classification indicates dust-tight and waterproof performance. The 7203SPD9CME and 7203SPD9CSE do not specify ingress protection ratings. Selection of the IP67-rated part is appropriate for applications requiring environmental sealing.

Q: Are there any compliance or certification differences between the three parts? A: All three parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications. RoHS and REACH status differ: the 7203SPD9CME is RoHS non-compliant and REACH unaffected; the 7203SPD9CSE is RoHS compliant and REACH affected; the 34BWDP31B4M2QT is RoHS compliant and REACH unaffected.
