MS12ASW30 Equivalent & Substitute Parts

Part Overview

The MS12ASW30 is a slide switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) configuration with 6A AC current rating at 125V. This component is designed for through-hole, right-angle mounting applications with non-shorting contact timing and silver alloy contacts. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS12ASW30 is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Current Rating: Minimum 6A AC capability required
• Voltage Rating: Minimum 125V AC rating required
• Contact Timing: Non-shorting (BBM) contact sequence
• Switch Function: On-On operation
• Mounting Type: Through hole, right angle configuration
• Termination Style: PC pin termination
• Contact Material: Silver alloy composition
• Operating Temperature Range: -30°C to 85°C minimum
• Mechanical Life: 100,000 cycles minimum
• Electrical Life: 25,000 cycles minimum
• RoHS Compliance: ROHS3 Compliant status

The MSN12ASW30 meets all specified electrical and mechanical parameters and is classified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The MSN12ASW30 is the manufacturer-recommended substitute for the obsolete MS12ASW30. Both components are manufactured by NKK Switches and maintain identical electrical and mechanical specifications across all critical parameters. The MSN12ASW30 carries active product status with current manufacturing support and inventory availability, whereas the MS12ASW30 is obsolete. Both parts maintain ROHS3 compliance and equivalent performance characteristics for SPDT slide switch applications requiring 6A at 125V AC with through-hole, right-angle mounting.

Frequently Asked Questions (FAQ)

Q: Can the MSN12ASW30 directly replace the MS12ASW30 in existing designs?

A: Yes. The MSN12ASW30 maintains identical electrical ratings (6A AC, 125V), circuit configuration (SPDT), contact timing (non-shorting BBM), mounting type (through hole, right angle), and termination style (PC pin). All mechanical and thermal specifications are equivalent.

Q: What is the primary reason for substitution?

A: The MS12ASW30 is obsolete. The MSN12ASW30 is the active equivalent from the same manufacturer with identical performance specifications.

Q: Are there packaging differences between these parts?

A: The MS12ASW30 is specified with standard packaging, while the MSN12ASW30 is supplied in bulk packaging. This does not affect component functionality or performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MS12ASW30 and MSN12ASW30 are ROHS3 compliant and carry EAR99 ECCN classification.

Q: What operating conditions are supported by the substitute?

A: The MSN12ASW30 operates across the same temperature range (-30°C to 85°C) with identical mechanical life (100,000 cycles) and electrical life (25,000 cycles) ratings.
