MJS22R Equivalent & Substitute Parts

Part Overview

The MJS22R is a slide switch manufactured by APEM Inc., configured as a Double Pole Double Throw (DPDT) switch with a 100mA DC current rating at 12V. This component features a through-hole, right-angle mounting configuration with PC pin termination and is designed for On-On switching applications. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MJS22R is determined by strict equivalence across the following critical parameters:

• Circuit configuration must remain DPDT
• Switch function must remain On-On
• Current rating must support minimum 100mA DC operation
• Voltage rating must support minimum 12V DC operation
• Mounting type must be through-hole, right-angle configuration
• Termination style must be PC pin
• Actuator length must be 2.50mm
• Switch travel must be 2.00mm
• Contact finish must be silver

The SS22SBH2 manufactured by NKK Switches meets all substitution criteria. This part maintains identical circuit topology, switching function, current capacity, and mechanical dimensions while providing enhanced voltage rating (30V) and extended operating temperature range (-15°C to 60°C). The SS22SBH2 is classified as active product status, ensuring continued availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The SS22SBH2 is the qualified substitute for the MJS22R based on functional equivalence and compliance alignment. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory consistency in system design. The SS22SBH2 provides superior voltage margin (30V versus 12V) and extended lower temperature operating range (-15°C versus -10°C), offering enhanced performance headroom for applications originally designed around the MJS22R specification.

The transition from obsolete MJS22R to active SS22SBH2 status ensures long-term component availability and supply chain continuity. Mechanical and electrical parameters remain equivalent, supporting direct substitution in existing PCB layouts and circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can the SS22SBH2 be used as a direct replacement for the MJS22R in existing designs?

A: Yes. The SS22SBH2 maintains identical circuit configuration (DPDT), switching function (On-On), current rating (100mA DC), mechanical dimensions (2.50mm actuator length, 2.00mm travel), and mounting configuration (through-hole, right-angle PC pin). The higher voltage rating (30V) and extended temperature range provide additional design margin without requiring circuit modification.

Q: What is the primary advantage of substituting to the SS22SBH2?

A: The SS22SBH2 is classified as active product status, ensuring continued manufacturing and supply availability. The MJS22R is obsolete, creating procurement risk and potential supply discontinuation. The SS22SBH2 provides equivalent electrical and mechanical performance with enhanced voltage and temperature specifications.

Q: Are there packaging differences between these components?

A: The MJS22R is supplied in standard packaging, while the SS22SBH2 is supplied in tray packaging. Both maintain identical through-hole, right-angle PC pin termination suitable for PCB assembly. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both components meet the same regulatory standards?

A: Yes. Both the MJS22R and SS22SBH2 are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for applications requiring environmental compliance certification.

Q: What is the contact timing difference noted in the parameter comparison?

A: The MJS22R contact timing is not specified in available documentation. The SS22SBH2 specifies shorting contact timing (Make-Before-Break, MBB), which ensures continuity between switching positions during transition. This characteristic is typical for DPDT On-On switches and does not affect substitution compatibility.
