MS12ANA03 Equivalent & Substitute Parts

Part Overview

The MS12ANA03 is a slide switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) configuration with a 6A AC rating at 125V. This through-hole component is designed for On-On switching applications with non-shorting contact timing. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS12ANA03 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (6A AC minimum)
• Voltage rating (125V AC minimum)
• Contact timing (Non-Shorting/BBM)
• Switch function (On-On)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C minimum)
• Mechanical life (100,000 cycles minimum)
• Electrical life (25,000 cycles minimum)
• RoHS compliance status

The MSN12ANA03, also manufactured by NKK Switches, meets these substitution criteria as an active product within the same manufacturer series, ensuring functional and electrical compatibility with the obsolete MS12ANA03.

Parameter Comparison

Engineering Selection Recommendations

The MSN12ANA03 is the direct substitute for the obsolete MS12ANA03. Both components are manufactured by NKK Switches and maintain identical electrical and mechanical specifications across all critical parameters. The MSN12ANA03 holds active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and identical export classification (EAR99), supporting regulatory requirements for new designs and legacy system maintenance.

Packaging differs between the two parts: the MS12ANA03 is supplied in Tray packaging, while the MSN12ANA03 is supplied in Bulk packaging. This distinction affects procurement quantities and handling procedures but does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MSN12ANA03 directly replace the MS12ANA03 in existing designs?

A: Yes. The MSN12ANA03 maintains identical electrical ratings (6A at 125V AC), circuit configuration (SPDT), contact timing (Non-Shorting/BBM), and mechanical specifications (100,000 cycle mechanical life, 25,000 cycle electrical life). Through-hole mounting and PC pin termination are identical, enabling direct substitution without circuit modification.

Q: What is the difference between the MS12ANA03 and MSN12ANA03?

A: The primary difference is product status: MS12ANA03 is obsolete, while MSN12ANA03 is active. Both are NKK Switches products with identical electrical and mechanical performance. Packaging differs (Tray versus Bulk), which affects procurement and handling but not functionality.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications, and operate within the same temperature range (-30°C to 85°C).

Q: Does packaging type affect electrical performance?

A: No. Packaging type (Tray versus Bulk) affects only procurement, storage, and handling procedures. Electrical and mechanical performance remains identical regardless of packaging format.

Q: What is the operating temperature range for both parts?

A: Both the MS12ANA03 and MSN12ANA03 operate across -30°C to 85°C, supporting applications in standard industrial and commercial environments.
