Substitute Part Grouping Explanation

Substitution eligibility for the 7203SD9V3ME is determined by strict equivalence across the following critical parameters:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Mounting type: Through Hole
• Actuator type and length: Standard Round, 12.45mm
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Electrical life: 40,000 Cycles
• Base product number: 7203SD
• Features: Epoxy Sealed Terminals

The C&K 7203SD9V3SE meets all electrical and mechanical parameters required for direct substitution. The primary distinction is product status: the 7203SD9V3SE is active and available, whereas the 7203SD9V3ME is obsolete.

Parameter Comparison

Engineering Selection Recommendations
