Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS22BSG13 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Mounting type must be Through Hole
• Termination style must be PC Pin
• Voltage rating must meet or exceed 28V (AC and DC)
• Current rating must support 0.4VA minimum
• Operating temperature range must encompass -30°C to 85°C or be compatible with application requirements
• RoHS compliance status must be ROHS3 or equivalent

Secondary Considerations:

• Contact material and finish (Copper with Gold preferred for signal integrity)
• Actuator length and switch travel (mechanical fit within PCB layout constraints)
• Electrical life rating (minimum 50,000 cycles preferred)

Substitute parts are grouped into two categories: direct manufacturer recommended alternatives and functionally equivalent cross-manufacturer options from C&K and Grayhill Inc.

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitute: MSN22BSG13

MSN22BSG13 is the manufacturer-recommended equivalent from NKK Switches with active product status. This part maintains design continuity with the original MS22BSG13 and is the preferred choice for direct replacement in existing designs.

Active Cross-Manufacturer Alternatives:

For applications requiring confirmed active product availability and extended electrical life, the following C&K parts meet core electrical requirements:

• 1201M2S3V3BE2 and 1201M2S3V3PE2: Rated 0.4VA at 20V DC with 100,000 cycle electrical life. Suitable for applications operating at or below 20V. Operating temperature limited to -30°C to 65°C.

• 1201M2S4V3BE2: Identical electrical specifications to 1201M2S3V3BE2 with longer actuator length (6.88mm vs. 4.72mm). Select based on mechanical clearance requirements.

• 1201M2S3V3GE2, 1201M2S3V3QE2, and 1201M2S3V3RE2: Rated 6A at 120V AC with 28V DC capability. These parts provide higher current capacity but reduced electrical life (40,000 cycles). Contact finish varies (Gold or Silver). Operating temperature limited to -30°C to 65°C.

Grayhill Inc. Alternatives:

• 48ASDP1S1V2RBT: Through-hole mount, 0.4VA at 20V, operating temperature -30°C to 85°C matching original specification range. Electrical life 30,000 cycles. RoHS compliant.

• 48ASDP1S1V2QAT and 48ASDP1S4V2QAT: Panel mount configuration (not through-hole). Suitable only if mechanical redesign is acceptable. Rated 5A at 125V AC with 28V DC capability.

Compliance Verification:

All recommended substitutes maintain ROHS3 or RoHS compliance and REACH unaffected status consistent with the original MS22BSG13. ECCN and HTSUS classifications remain unchanged across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part rated at 20V DC instead of 28V DC?

A: No. The MS22BSG13 is rated 28V DC. Substitute parts must meet or exceed this voltage rating. Parts rated 20V DC (such as 1201M2S3V3BE2) are not suitable for 28V applications and present electrical safety and reliability risks.

Q: What is the difference between the C&K 1201M2S3V3BE2 and 1201M2S4V3BE2?

A: Both parts are electrically identical (0.4VA, 20V, 100,000 cycle life, ROHS3 compliant). The primary difference is actuator length: 1201M2S3V3BE2 has 4.72mm actuator length, while 1201M2S4V3BE2 has 6.88mm. Select based on PCB layout and mechanical clearance constraints.

Q: Why do some substitute parts have higher current ratings (6A) than the original (0.4VA)?

A: Higher current-rated parts (1201M2S3V3GE2, 1201M2S3V3QE2, 1201M2S3V3RE2) are functionally compatible but represent different product lines within the DPDT through-hole category. They are suitable for applications requiring higher current capacity. However, they have reduced electrical life (40,000 cycles vs. 50,000 cycles original) and lower operating temperature ceiling (-30°C to 65°C vs. -30°C to 85°C).

Q: Is MSN22BSG13 a direct replacement for MS22BSG13?

A: MSN22BSG13 is the manufacturer-recommended equivalent from NKK Switches. However, detailed electrical and mechanical specifications are not provided in available documentation. Verification with NKK Switches technical support is recommended before design implementation.

Q: Can I use Grayhill 48ASDP1S1V2QAT or 48ASDP1S4V2QAT as substitutes?

A: These parts are panel-mount configuration, not through-hole. They are electrically compatible (5A at 125V AC, 28V DC) but require mechanical redesign of the PCB mounting interface. Use only if panel-mount conversion is acceptable for your application.

Q: What is the impact of contact finish differences (Gold vs. Silver)?

A: Contact finish affects signal integrity and corrosion resistance. The original MS22BSG13 uses gold-plated contacts. Gold finish is preferred for low-signal applications and superior corrosion resistance. Silver-finish alternatives (1201M2S3V3QE2, Grayhill parts) are acceptable for general switching applications but may have different long-term reliability characteristics in corrosive environments.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitutes are RoHS compliant. MSN22BSG13, C&K parts (1201M2S series), and most Grayhill parts carry ROHS3 or RoHS certification. Verify specific compliance documentation for your regulatory requirements.

Q: What is the minimum electrical life requirement for my application?

A: The original MS22BSG13 specifies 50,000 electrical cycles. C&K alternatives (1201M2S3V3BE2, 1201M2S3V3PE2, 1201M2S4V3BE2) offer 100,000 cycles, exceeding original specifications. Higher-current C&K parts and Grayhill alternatives provide 30,000 to 40,000 cycles. Select based on your application's switching frequency and expected product lifetime.
