MS13ASG40 Equivalent & Substitute Parts Reference

Part Overview

The MS13ASG40 is a slide switch manufactured by NKK Switches, configured as a Single Pole Double Throw (SPDT) with non-shorting contact timing. This through-hole, right-angle vertical switch is rated for 0.4VA at 28V AC/DC and features a standard polybutylene terephthalate actuator with gold-plated copper contacts. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and legacy system support.

Substitute Part Grouping Explanation

Substitution of the MS13ASG40 is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain SPDT with non-shorting contact timing to maintain functional compatibility with existing circuit designs. Electrical ratings must match or exceed the 0.4VA at 28V AC/DC specification. Mounting configuration must be through-hole, right-angle, vertical orientation with PC pin termination to ensure mechanical fit within the PCB layout. Contact material and finish specifications (copper with gold plating) must be maintained to preserve electrical performance and reliability. Operating temperature range must encompass the -30°C to 85°C specification. RoHS3 compliance is required for regulatory alignment.

The MSN13ASG40, manufactured by NKK Switches, meets all these criteria and is classified as the manufacturer-recommended substitute.

Engineering Selection Recommendations

The MSN13ASG40 is the direct substitute for the obsolete MS13ASG40. Both parts are manufactured by NKK Switches and maintain identical electrical and mechanical specifications. The MSN13ASG40 carries active product status, ensuring availability and ongoing manufacturer support. Both parts maintain ROHS3 compliance and equivalent regulatory certifications (ECCN: EAR99, HTSUS: 8536.50.9050). Selection of the MSN13ASG40 eliminates obsolescence risk while preserving full functional and physical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the MSN13ASG40 be used as a direct replacement for the MS13ASG40?

A: Yes. Both parts are manufactured by NKK Switches with identical circuit configuration (SPDT), contact timing (non-shorting), electrical ratings (0.4VA at 28V AC/DC), mounting type (through-hole, right-angle, vertical), and termination style (PC pin). The MSN13ASG40 is the manufacturer-recommended substitute.

Q: What is the primary reason for substitution?

A: The MS13ASG40 is obsolete. The MSN13ASG40 is an active product that provides equivalent functionality and maintains full compatibility with legacy designs.

Q: Are there any differences in mechanical fit?

A: No. Both parts share identical mounting specifications: through-hole, right-angle, vertical orientation with PC pin termination. PCB layout modifications are not required.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the MS13ASG40 and MSN13ASG40 are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications.

Q: What are the critical parameters that must match for substitution?

A: Circuit configuration (SPDT), contact timing (non-shorting), electrical rating (0.4VA at 28V AC/DC), mounting type (through-hole, right-angle, vertical), termination style (PC pin), and operating temperature range (-30°C to 85°C) must all remain constant.
