MS22BNW03 Equivalent & Substitute Parts

Part Overview

The MS22BNW03 is a slide switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) switch with a 6A AC rating at 125V. This through-hole mounted component features non-shorting contact timing and is designed for on-on switching applications. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS22BNW03 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (DPDT), contact timing (non-shorting), switch function (on-on), current rating (6A AC), and voltage rating (125V AC) must remain identical. These parameters define the electrical performance and safety envelope of the component within the application circuit.

Mechanical Parameters: Mounting type (through hole), termination style (PC pin), and actuator specifications must match to ensure physical compatibility with existing PCB layouts and assembly processes.

Material & Environmental Parameters: Contact material (silver alloy), operating temperature range (-30°C to 85°C), and mechanical/electrical life ratings establish reliability and longevity requirements.

Compliance Parameters: RoHS3 compliance and REACH status ensure regulatory alignment for the application environment.

The MSN22BNW03, also manufactured by NKK Switches, meets these substitution criteria as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MSN22BNW03 is the qualified substitute for the obsolete MS22BNW03. Both components are manufactured by NKK Switches and maintain identical electrical, mechanical, and material specifications across all critical parameters. The MSN22BNW03 carries active product status with current inventory availability, making it the appropriate selection for replacement applications.

Both parts maintain ROHS3 compliance and are classified under ECCN EAR99 with matching HTSUS codes (8536.50.9050), ensuring regulatory and trade compliance equivalence. The transition from the obsolete MS22BNW03 to the active MSN22BNW03 introduces no technical risk when applied within the original design specifications.

Frequently Asked Questions (FAQ)

Q: Can the MSN22BNW03 be used as a direct replacement for the MS22BNW03 in existing designs?

A: Yes. The MSN22BNW03 is electrically and mechanically equivalent to the MS22BNW03 across all specified parameters, including circuit configuration, current and voltage ratings, mounting type, and termination style. No design modifications are required.

Q: What is the primary difference between the MS22BNW03 and MSN22BNW03?

A: The MS22BNW03 is obsolete with no current manufacturing, while the MSN22BNW03 is an active product with current inventory. All functional and physical specifications remain identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring equivalent regulatory status.

Q: What parameters must remain constant when selecting a substitute for the MS22BNW03?

A: The DPDT circuit configuration, 6A AC current rating, 125V AC voltage rating, non-shorting contact timing, on-on switch function, through-hole mounting, PC pin termination, and silver alloy contact material are non-negotiable for substitution.

Q: Is the MSN22BNW03 available in the same packaging as the MS22BNW03?

A: Both parts are supplied in bulk packaging, consistent with standard component distribution for through-hole mounted switches.
