MDS003C Equivalent & Substitute Parts

Part Overview

The MDS003C is a snap-action SPDT switch manufactured by C&K, designed for through-hole, right-angle mounting applications requiring 300mA DC at 30V. This component features a straight lever actuator with PC pin termination and is rated for 30,000 electrical and mechanical cycles. The MDS003C is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the obsolete MDS003C is based on electrical and mechanical parameter alignment within the MDS series. The primary substitute, MDS6500AL02RS, maintains identical electrical specifications: SPDT circuit, 300mA DC current rating, and 30V DC voltage rating. Both components share the same actuator type (straight lever), mounting configuration (through-hole, right-angle), and termination style (PC pin). Operating force and release force values are identical at 50gf and 3.000gf respectively. Cycle life ratings match at 30,000 cycles for both electrical and mechanical operation. The substitute part is currently active in production, ensuring long-term availability and supply chain stability.

Key substitution parameters:

• Circuit: SPDT
• Current Rating: 300mA DC
• Voltage Rating: 30V DC
• Actuator: Lever, Straight
• Mounting: Through Hole, Right Angle
