MDP S Pushbutton Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The MDP S is a through-hole pushbutton switch manufactured by C&K, configured as a single-pole single-throw normally open (SPST-NO) keyswitch with 0.1A rated current at 100V AC/DC. This component features tactile feedback, a black plunger actuator, and PC pin termination suitable for panel-mount applications.

The MDP S is classified as obsolete. Locating direct replacements is necessary for ongoing production support, maintenance, and new design implementations where this switch type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDP S is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Current and voltage ratings (100mA at 100V AC/DC)
• Actuator type and mechanical interface (plunger for cap)
• Termination style (PC pin)
• Mounting method (through hole)
• Operating temperature range (-25°C to 70°C)
• Electrical life specification (200,000 cycles)

The MDPSLFS is a direct substitute within the same MDP series, maintaining identical electrical and mechanical specifications while offering improved product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MDPSLFS is the direct equivalent substitute for the MDP S. Both components share identical electrical and mechanical specifications, ensuring functional interchangeability in circuit applications.

The MDPSLFS offers two significant advantages over the obsolete MDP S:

1. Active product status with confirmed inventory availability (2,398 units in stock versus 648 units for the MDP S)
2. ROHS3 compliance certification, meeting current environmental and regulatory requirements

Selection of the MDPSLFS is appropriate for new designs, production continuity, and maintenance applications where the MDP S specification is required.

Frequently Asked Questions (FAQ)

Q: Are the MDP S and MDPSLFS electrically interchangeable?

A: Yes. Both components are rated for 100mA at 100V AC/DC with SPST-NO configuration and identical electrical life specifications of 200,000 cycles.

Q: What are the mechanical differences between these parts?

A: There are no mechanical differences. Both use plunger-type actuators with black caps, PC pin termination, and through-hole mounting.

Q: Why is the MDPSLFS preferred over the MDP S?

A: The MDPSLFS is an active product with higher inventory availability and ROHS3 compliance certification. The MDP S is obsolete and does not meet current environmental standards.

Q: Can the MDPSLFS be used as a direct replacement in existing designs?

A: Yes. The MDPSLFS maintains identical form factor, pinout, and electrical performance, allowing direct substitution without circuit modification.

Q: What is the packaging difference?

A: The MDP S is supplied in standard packaging, while the MDPSLFS is supplied in tray packaging. This does not affect component functionality or performance.

Q: Are there any compliance or certification differences?

A: The MDPSLFS carries ROHS3 compliance and REACH Unaffected status. The MDP S is RoHS non-compliant. Both share EAR99 ECCN classification and identical HTSUS codes.
