MS22AFG01 Equivalent & Substitute Parts

Part Overview

The MS22AFG01 is a slide switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) panel mount component with a 0.4VA current rating at 28V. This switch features non-shorting contact timing (BBM), gold-plated copper contacts, and solder lug termination with epoxy sealed terminals. The product is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS22AFG01 is based on strict equivalence of the following electrical and mechanical parameters:

• Circuit configuration (DPDT)
• Contact timing specification (Non-Shorting BBM)
• Switch function (On-On)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)
• Contact material and finish (Copper with Gold plating)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications

The MSN22AFG01 meets all these criteria and is identified as the manufacturer-recommended substitute part from NKK Switches.

Parameter Comparison

Engineering Selection Recommendations

The MSN22AFG01 is the manufacturer-recommended substitute for the obsolete MS22AFG01. Both parts are manufactured by NKK Switches and maintain identical ROHS3 compliance and EAR99 export classification. The transition from the obsolete MS22AFG01 to the active MSN22AFG01 is supported by equivalent electrical specifications, mechanical characteristics, and regulatory certifications. The primary distinction is product status: the MS22AFG01 is obsolete while the MSN22AFG01 remains in active production, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MSN22AFG01 directly replace the MS22AFG01 in existing applications?

A: Yes. Both parts share identical circuit configuration (DPDT), contact timing (Non-Shorting BBM), current and voltage ratings (0.4VA at 28V), mounting type (Panel Mount), and termination style (Solder Lug). The MSN22AFG01 is the manufacturer-recommended substitute.

Q: What is the difference between the tray and bulk packaging options?

A: Packaging affects logistics and handling but does not alter electrical or mechanical performance. Tray packaging (MS22AFG01) provides organized component presentation, while bulk packaging (MSN22AFG01) is typically used for high-volume procurement. Selection depends on assembly process requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the MS22AFG01 and MSN22AFG01 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications.

Q: Why is the MS22AFG01 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The MSN22AFG01 represents the current active equivalent from the manufacturer, ensuring continued availability and support.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in circuit configuration (DPDT), contact timing (Non-Shorting BBM), current rating (0.4VA), voltage rating (28V AC/DC), mounting type (Panel Mount), termination style (Solder Lug), and operating temperature range (-30°C to 85°C).
