MK22-B-2 Equivalent & Substitute Parts Reference

Part Overview

The MK22-B-2 is an active molded body reed switch manufactured by Standex-Meder Electronics, configured as a single-pole single-throw normally open (SPST-NO) device. This surface mount component operates at 200V AC/DC with a switching capacity of 1A and rated power of 20W. The device is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to address application requirements where current capacity, power rating, or packaging format differ from the primary specification while maintaining core electrical and mechanical compatibility within the MK series product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MK22-B-2 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPST-NO)
• Voltage rating (200V AC/DC)
• Operate range (10 ~ 15AT)
• Mounting type (Surface Mount)
• Termination style (Gull Wing)
• Operating temperature range (-40°C ~ 130°C)
• Compliance certifications (RoHS3, REACH Unaffected)

Variable Parameters Allowing Substitution:

• Current - Switching capacity
• Power - Rated capacity
• Packaging format (Tape & Reel vs. Cut Tape/Digi-Reel)
• Operate and release timing characteristics
• Physical body dimensions
• Capacitance specifications

The MK16-B-2 qualifies as a substitute part because it maintains all mandatory matching parameters while offering reduced current (400mA vs. 1A) and power (10W vs. 20W) ratings. This substitution is valid for applications requiring lower switching current within the same voltage and temperature operating envelope.

Parameter Comparison

Engineering Selection Recommendations

MK22-B-2 Primary Selection: Select the MK22-B-2 for applications requiring full 1A switching current capacity at 200V with 20W power rating. This part maintains active product status with RoHS3 compliance and unlimited moisture sensitivity rating, suitable for standard industrial switching applications.

MK16-B-2 Substitute Selection: The MK16-B-2 substitutes the MK22-B-2 in applications where switching current does not exceed 400mA and power dissipation remains below 10W. Both parts share identical voltage ratings (200V AC/DC), operate range (10 ~ 15AT), mounting configuration, and temperature operating envelope (-40°C ~ 130°C). Both maintain RoHS3 compliance and REACH unaffected status.

Packaging Consideration: The MK22-B-2 is supplied in Tape & Reel format, while the MK16-B-2 is available in Cut Tape and Digi-Reel packaging. Packaging selection depends on assembly process requirements and volume specifications.

Frequently Asked Questions (FAQ)

Q: Can the MK16-B-2 replace the MK22-B-2 in all applications?

A: No. The MK16-B-2 is a valid substitute only when the application switching current requirement does not exceed 400mA and power dissipation remains below 10W. If the circuit requires the full 1A switching capacity or 20W power rating of the MK22-B-2, the MK16-B-2 is not suitable.

Q: What are the key electrical parameters that must match for substitution?

A: Circuit configuration (SPST-NO), voltage rating (200V AC/DC), operate range (10 ~ 15AT), and operating temperature range (-40°C ~ 130°C) must remain identical. These parameters define the core functional compatibility between MK22-B-2 and MK16-B-2.

Q: Are there differences in switching speed between these parts?

A: Yes. The MK22-B-2 has an operate time of 0.5 ms and release time of 0.1 ms, while the MK16-B-2 has an operate time of 0.6 ms and release time of 0.05 ms. Applications with strict timing requirements must account for these differences.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MK22-B-2 and MK16-B-2 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Compliance certifications are identical between the two parts.

Q: What is the difference in packaging between these parts?

A: The MK22-B-2 is supplied in Tape & Reel (TR) format for automated assembly. The MK16-B-2 is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection should align with the assembly process and volume requirements of the application.

Q: Can the MK22-B-2 be used in place of the MK16-B-2?

A: Yes. The MK22-B-2 can substitute the MK16-B-2 in any application. The higher current (1A vs. 400mA) and power (20W vs. 10W) ratings of the MK22-B-2 provide additional capacity margin. However, this substitution may not be cost-effective if the application only requires 400mA switching capacity.
