M2025SS1G01 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The M2025SS1G01 is a panel-mount toggle switch manufactured by NKK Switches, configured as a Double Pole Double Throw (DPDT) switch with momentary operation. This component is rated for 0.4VA at 28V AC/DC with a non-illuminated standard round actuator. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2025SS1G01 is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT to maintain electrical functionality
• Switch Function: Must be On-Momentary to preserve operational behavior
• Current Rating: Must support minimum 0.4VA (AC/DC)
• Voltage Rating: Must support minimum 28V AC and 28V DC
• Mounting Type: Must be Panel Mount with 1/4-40 bushing thread for mechanical compatibility
• Termination Style: Must be Solder Lug for connection compatibility
• Operating Temperature: Must encompass -30°C to 85°C range
• Compliance: Must maintain ROHS3 compliance for regulatory alignment

The C&K 7208SYZBE qualifies as a substitute based on matching circuit configuration, switch function, current rating, mounting type, termination style, and operating temperature range. Voltage rating differences and electrical life variations are noted in the parameter comparison.

Engineering Selection Recommendations

The C&K 7208SYZBE is an active production substitute for the obsolete M2025SS1G01. Both components maintain ROHS3 compliance and identical circuit configuration, switch function, current rating, and operating temperature specifications.

Selection considerations based on provided specifications:

• Voltage Rating: The 7208SYZBE is rated for 20V AC/DC versus the M2025SS1G01's 28V rating. Applications operating at or below 20V are fully compatible. Applications requiring 28V operation must be evaluated against the substitute's lower voltage specification.

• Electrical Life: The M2025SS1G01 supports 50,000 cycles while the 7208SYZBE supports 40,000 cycles. High-cycle-count applications should account for this difference.

• Panel Cutout Dimensions: The M2025SS1G01 requires a 6.50mm diameter hole while the 7208SYZBE requires 6.35mm. Panel modifications may be necessary depending on existing hole dimensions.

• Regulatory Status: The 7208SYZBE is REACH Affected, whereas the M2025SS1G01 is REACH Unaffected. Applications subject to REACH regulations should confirm compliance requirements with the substitute part.

• Availability: The 7208SYZBE is currently in active production with documented inventory, whereas the M2025SS1G01 is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7208SYZBE directly replace the NKK M2025SS1G01 in all applications?

A: The 7208SYZBE matches the M2025SS1G01 in circuit configuration, switch function, current rating, and operating temperature. However, the lower voltage rating (20V versus 28V) and reduced electrical life (40,000 versus 50,000 cycles) must be evaluated against specific application requirements.

Q: What is the impact of the voltage rating difference?

A: The M2025SS1G01 is rated for 28V AC/DC while the 7208SYZBE is rated for 20V AC/DC. If your application operates at 20V or below, the substitute is fully compatible. Applications requiring 28V operation must confirm that the lower-rated substitute meets system safety and performance requirements.

Q: Are the panel mounting dimensions compatible?

A: Both switches use 1/4-40 bushing threads for mounting. However, the panel cutout diameter differs slightly: M2025SS1G01 requires 6.50mm while the 7208SYZBE requires 6.35mm. Existing panel holes may require modification or enlargement to accommodate the substitute.

Q: What is the difference in electrical life between these parts?

A: The M2025SS1G01 is rated for 50,000 electrical cycles while the 7208SYZBE is rated for 40,000 cycles. Applications with high switching frequency should account for this 20% reduction in rated cycle life.

Q: Are both parts RoHS compliant?

A: Yes, both the M2025SS1G01 and 7208SYZBE are ROHS3 compliant. However, the 7208SYZBE is REACH Affected while the M2025SS1G01 is REACH Unaffected. Applications subject to REACH regulations should verify compliance requirements.

Q: What is the actuator length difference?

A: The M2025SS1G01 has a 10.50mm actuator length while the 7208SYZBE has a 10.67mm length. This minimal 0.17mm difference is unlikely to affect panel-mount applications but should be confirmed against specific mechanical constraints.

Q: Is the 7208SYZBE currently available?

A: Yes, the C&K 7208SYZBE is in active production status with documented inventory availability, whereas the M2025SS1G01 is obsolete.
