C&K 7208SYCBE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7208SYCBE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This switch is currently active in production and widely used in control panel applications requiring low-voltage switching. Equivalent and substitute parts may be necessary due to supply chain constraints, end-of-life considerations for certain alternatives, or specific application requirements that align with available inventory.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7208SYCBE is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT
• Switch Function: Must be On-Mom
• Mounting Type: Must be Panel Mount
• Termination Style: Must be PC Pin
• Voltage Rating (AC/DC): Must support minimum 20V AC and 20V DC
• Current Rating: Must support minimum 0.4VA
• Panel Cutout Dimensions: Must accommodate Circular 6.35mm diameter or compatible bushing thread (1/4-40)
• Operating Temperature: Must cover -30°C to 85°C range
• RoHS Compliance: Must be ROHS3 Compliant

Substitute parts are grouped based on strict adherence to these parameters. Parts that exceed the voltage or current ratings remain compatible. Parts with reduced electrical life, obsolete status, or non-standard panel cutout dimensions are identified for engineering review.

Parameter Comparison

Engineering Selection Recommendations

3-1825138-6 (TE Connectivity ALCOSWITCH Switches)

This part is electrically equivalent to the 7208SYCBE with identical voltage and current ratings (0.4VA at 20V AC/DC). Both parts maintain ROHS3 compliance and identical panel mounting specifications. The primary distinction is reduced electrical life (6,000 cycles versus 40,000 cycles). This part is currently active in production. Selection is appropriate for applications where electrical life requirements do not exceed 6,000 cycles.

M2025SS1G03 (NKK Switches)

This part exceeds the voltage rating of the 7208SYCBE (28V AC/DC versus 20V AC/DC) while maintaining identical current rating and circuit configuration. Electrical life is superior at 50,000 cycles. Panel cutout diameter is 6.50mm, requiring panel modification or adapter consideration. Product status is obsolete. ROHS3 compliance and operating temperature range are maintained. Selection is appropriate for applications requiring higher voltage tolerance and extended electrical life, provided panel cutout compatibility is addressed.

M2025SS1W03 (NKK Switches)

This part significantly exceeds the electrical specifications of the 7208SYCBE with current rating of 6A (AC) and 3A (DC), and voltage rating of 125V AC and 30V DC. Panel cutout diameter is 6.50mm. Product status is obsolete. ROHS3 compliance and operating temperature range are maintained. Selection is appropriate only for applications requiring substantially higher power handling capability and where panel cutout modification is feasible.

Frequently Asked Questions (FAQ)

Q: Can the 3-1825138-6 directly replace the 7208SYCBE?

A: Yes, for applications where electrical life does not exceed 6,000 cycles. Both parts share identical voltage ratings (20V AC/DC), current rating (0.4VA), circuit configuration (DPDT), and panel mounting specifications (6.35mm cutout, 1/4-40 bushing thread). The 3-1825138-6 is currently active in production.

Q: What is the significance of the panel cutout diameter difference between 6.35mm and 6.50mm?

A: The 6.50mm cutout diameter on NKK parts (M2025SS1G03 and M2025SS1W03) requires a larger panel opening than the 7208SYCBE and 3-1825138-6. Panel modification or use of an adapter bushing is necessary for mechanical compatibility.

Q: Why are the NKK parts listed as obsolete?

A: Product status reflects manufacturer availability. Obsolete parts may have limited inventory but remain available through existing stock channels. Current production status should be confirmed with the supplier before design selection.

Q: Can the M2025SS1W03 be used in place of the 7208SYCBE?

A: Electrical compatibility exists due to higher voltage and current ratings. However, the 6.50mm panel cutout diameter requires panel modification. Selection should be based on application requirements for higher power handling and panel design constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—7208SYCBE, 3-1825138-6, M2025SS1G03, and M2025SS1W03—maintain ROHS3 compliance.

Q: What is the electrical life consideration for each part?

A: The 7208SYCBE provides 40,000 cycles, the 3-1825138-6 provides 6,000 cycles, the M2025SS1G03 provides 50,000 cycles, and the M2025SS1W03 provides 25,000 cycles. Application duty cycle requirements should determine selection.
