Substitute Part Grouping Explanation

Substitution of the MS22ANW03 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Current Rating: 6A AC minimum requirement
• Voltage Rating: 125V AC minimum requirement
• Contact Timing: Non-shorting (BBM) operation
• Switch Function: On-On configuration
• Mounting Type: Through-hole compatibility
• Termination Style: PC pin termination
• Contact Material: Silver alloy contacts
• Environmental Compliance: ROHS3 compliance and REACH status

The MSN22ANW03, manufactured by NKK Switches, meets all specified electrical and mechanical parameters required for direct substitution. Both parts share identical electrical ratings, contact characteristics, and mounting specifications, establishing functional equivalence for replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the MSN22ANW03 directly replace the MS22ANW03 in existing circuit designs?

A: Yes. Both components share identical DPDT circuit configuration, 6A AC current rating, 125V AC voltage rating, non-shorting contact timing, and through-hole PC pin termination. Electrical and mechanical compatibility is established across all specified parameters.

Q: What is the primary reason for substitution?

A: The MS22ANW03 is classified as obsolete. The MSN22ANW03 is an active product from the same manufacturer, providing continued availability and manufacturer support for replacement applications.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, carry identical ECCN and HTSUS classifications, and share equivalent environmental compliance status.

Q: Does the MSN22ANW03 maintain the same operating temperature range?

A: The operating temperature range for the MSN22ANW03 is not specified in the provided data. Verification of thermal operating parameters should be conducted against the MSN22ANW03 datasheet if temperature extremes are critical to the application.

Q: Are there packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. The MS22ANW03 shows 20,400 pieces in stock (legacy inventory), while the MSN22ANW03 shows 1,115 pieces in current stock. For new designs or ongoing production, the MSN22ANW03 is the recommended selection due to active product status.
