MS22AFW01 Equivalent & Substitute Parts

Part Overview

The MS22AFW01 is a slide switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) panel mount switch with a 6A AC rating at 125V. This component features non-shorting contact timing (BBM), silver alloy contacts, and solder lug termination. The product is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS22AFW01 is determined by strict alignment of the following electrical and mechanical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Current and Voltage Ratings: 6A AC at 125V minimum
• Contact Timing: Non-shorting (BBM) operation required
• Mounting Type: Panel mount configuration
• Termination Style: Solder lug connections
• Contact Material: Silver alloy composition
• Environmental Compliance: ROHS3 compliance and REACH unaffected status

The MSN22AFW01, manufactured by NKK Switches, meets all specified electrical and mechanical requirements for direct substitution. Both parts share identical circuit topology, current/voltage ratings, contact material composition, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MSN22AFW01 is the direct substitute for the obsolete MS22AFW01. Both components are manufactured by NKK Switches and maintain identical electrical specifications, circuit topology, and contact characteristics. The MSN22AFW01 carries active product status with current manufacturing support, whereas the MS22AFW01 is obsolete. Both parts maintain ROHS3 compliance and are suitable for equivalent circuit applications. The transition from MS22AFW01 to MSN22AFW01 presents no electrical or mechanical incompatibility for panel mount DPDT switching applications requiring 6A AC at 125V operation.

Frequently Asked Questions (FAQ)

Q: Can the MSN22AFW01 directly replace the MS22AFW01 in existing applications?

A: Yes. Both parts share identical DPDT circuit configuration, 6A AC / 125V ratings, silver alloy contacts, solder lug termination, and panel mount design. Electrical and mechanical compatibility is complete.

Q: What is the primary reason for substitution?

A: The MS22AFW01 is classified as obsolete. The MSN22AFW01 is an active product from the same manufacturer with equivalent specifications, ensuring continued availability and supply chain continuity.

Q: Are there differences in packaging between these parts?

A: The MS22AFW01 is specified with dash packaging notation, while the MSN22AFW01 is supplied in bulk packaging. This represents a packaging format difference only and does not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MS22AFW01 and MSN22AFW01 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What parameters must remain constant for substitution validity?

A: Circuit configuration (DPDT), current rating (6A AC), voltage rating (125V), contact material (silver alloy), mounting type (panel mount), and termination style (solder lug) must all be maintained for direct substitution.
