SS22SDP4/3 Equivalent & Substitute Parts

Part Overview

The SS22SDP4/3 is a slide switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) switch with a 0.4VA current rating at 28V. This through-hole mounted component features phosphor bronze contacts with gold finish and is designed for On-On switching applications with shorting contact timing (MBB). The part is currently listed as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS22SDP4/3 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Current rating (0.4VA AC/DC)
• Voltage rating (28V AC and DC)
• Contact timing (Shorting/MBB)
• Switch function (On-On)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Contact material and finish (Phosphor Bronze with Gold plating)
• Actuator specifications (2.00mm length and travel)
• Operating temperature range (-15°C to 60°C)
• Mechanical and electrical life (10,000 cycles)

The SS22SBP4 meets all these criteria and is classified as an equivalent substitute. The primary distinction is product status: SS22SBP4 is active and available, whereas SS22SDP4/3 is obsolete.

Parameter Comparison
