Substitute Part Grouping Explanation
Substitution for the MS22BSW13 is determined by the following critical parameters:
- Circuit Configuration: DPDT topology is mandatory for functional equivalence
- Switch Function: On-On operation must be maintained
- Current Rating: Minimum 6A capability required for AC applications
- Voltage Rating: Minimum 125V AC rating required
- Mounting Type: Through-hole mounting is required for PCB compatibility
- Termination Style: PC pin termination is required for board assembly
- Contact Timing: Non-shorting operation preferred for signal integrity
- Environmental Compliance: ROHS3 compliance and REACH unaffected status required
Substitute parts are grouped into two categories:
Category 1 - Direct Manufacturer Equivalent: MSN22BSW13 (NKK Switches) provides identical electrical and mechanical specifications with active product status.
Category 2 - Cross-Manufacturer Alternatives: C&K 1000 series (1201M2S3V3GE2, 1201M2S3V3QE2, 1201M2S3V3RE2) and Grayhill 48A series (48ASDP1S4V2QAT, 48ASDP1S1V2QAT) provide DPDT through-hole switching with 6A/120V+ ratings and active product status. These alternatives maintain core electrical performance within specified operating ranges.
Category 3 - Lower-Rated Alternatives: C&K 1201M2S3V3BE2, 1201M2S4V3BE2, and Grayhill 48ASDP1S1V2RBT are rated for 0.4VA at 20V and are suitable only for applications with reduced power requirements.

Engineering Selection Recommendations
Primary Recommendation: MSN22BSW13 (NKK Switches) is the preferred direct equivalent. This part maintains identical circuit topology and switching characteristics while offering active product status and guaranteed availability. Both parts share ROHS3 compliance and REACH unaffected status.
Secondary Recommendations for Full Electrical Equivalence: 1201M2S3V3GE2 and 1201M2S3V3QE2 (C&K 1000 series) provide equivalent 6A/120V DPDT through-hole switching with active product status and ROHS3 compliance. These parts exceed the electrical life specification of the original part (40,000 cycles vs. 25,000 cycles). Operating temperature range is reduced to -30°C to 65°C, which may impact applications requiring the full -30°C to 85°C range.
Alternative for Equivalent Performance: 48ASDP1S4V2QAT (Grayhill 48A series) provides 5A/125V DPDT switching with matching operating temperature range (-30°C to 85°C) and ROHS compliance. This part is panel-mounted rather than through-hole, requiring mechanical redesign for PCB integration.
Not Recommended for Direct Substitution: Parts rated for 0.4VA at 20V (1201M2S3V3BE2, 1201M2S4V3BE2, 48ASDP1S1V2RBT) do not meet the current and voltage requirements of the original specification and are suitable only for reduced-power applications.
Frequently Asked Questions (FAQ)
Q: Can MSN22BSW13 be used as a direct replacement for MS22BSW13?
A: Yes. MSN22BSW13 is the NKK Switches equivalent part with active product status. Both parts share identical DPDT on-on configuration, through-hole mounting, and PC pin termination. MSN22BSW13 is the recommended replacement for obsolete MS22BSW13 applications.
Q: What are the key differences between C&K 1201M2S3V3GE2 and the original MS22BSW13?
A: Both parts provide 6A/120V DPDT through-hole switching with equivalent electrical performance. Differences include: contact material (copper vs. silver alloy), reduced operating temperature range (-30°C to 65°C vs. -30°C to 85°C), and higher electrical life rating (40,000 vs. 25,000 cycles). Applications requiring operation above 65°C are not suitable for this substitute.
Q: Why is 48ASDP1S4V2QAT listed as an alternative if it is panel-mounted?
A: 48ASDP1S4V2QAT provides equivalent electrical specifications (5A/125V DPDT on-on) and matches the full operating temperature range (-30°C to 85°C). Panel mounting requires mechanical redesign but may be acceptable for applications where board-level integration is not mandatory. This part is included for design flexibility in applications permitting alternative mounting approaches.
Q: Are low-power alternatives (0.4VA at 20V) suitable for MS22BSW13 applications?
A: No. Low-power alternatives are rated for significantly reduced current (0.4VA) and voltage (20V) compared to the original specification (6A at 125V). These parts are suitable only for applications with substantially lower power requirements and cannot be used as direct substitutes for the MS22BSW13.
Q: What compliance certifications should I verify when selecting a substitute?
A: All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, matching the original MS22BSW13 certifications. Verify that selected parts meet your specific application's environmental and regulatory requirements before final design approval.
Q: Does contact material affect substitution compatibility?
A: Contact material differences (silver alloy vs. copper or copper alloy) may affect contact resistance and signal integrity in specific applications. Silver alloy contacts provide superior conductivity. If contact material is critical to your application, verify performance with the substitute part's contact material before implementation.
