Substitute Part Grouping Explanation

Substitute components for the M2019TYG03 are identified based on the following criteria:

• Manufacturer alignment: NKK Switches product family
• Product classification: Switch category with compatible actuation mechanism
• Compliance equivalence: Matching ECCN and HTSUS classifications
• Functional category: Rocker switch variants within the same electrical classification

The MN19TYG03 qualifies as a manufacturer-recommended substitute based on shared compliance framework (ECCN EAR99, HTSUS 8536.50.9065) and NKK Switches product lineage, despite the actuation mechanism difference (rocker versus toggle).

Parameter Comparison

Engineering Selection Recommendations

The MN19TYG03 is designated as the manufacturer-recommended substitute for the obsolete M2019TYG03. Both components share identical compliance classifications (ECCN EAR99, HTSUS 8536.50.9065), confirming regulatory equivalence for procurement and export purposes. The MN19TYG03 maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete M2019TYG03. Component selection should prioritize the active MN19TYG03 for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Why is the M2019TYG03 listed as obsolete? A: The M2019TYG03 has reached end-of-life status within NKK Switches product portfolio. The MN19TYG03 represents the active replacement within the same compliance and electrical classification framework.

Q: Are the M2019TYG03 and MN19TYG03 electrically equivalent? A: Both components share identical ECCN and HTSUS classifications, confirming regulatory and compliance equivalence. Functional compatibility depends on specific circuit requirements and mechanical form factor accommodation.

Q: What is the difference between a toggle switch and a rocker switch? A: The primary difference is actuation mechanism. The M2019TYG03 uses toggle actuation, while the MN19TYG03 uses rocker actuation. Both are classified under the same electrical switch category (HTSUS 8536.50.9065).

Q: Is inventory availability a factor in component selection? A: Both components maintain current inventory stock (M2019TYG03: 1122 Pcs; MN19TYG03: 988 Pcs). For new designs, the active MN19TYG03 is recommended to ensure sustained supply availability beyond current stock levels.

Q: Can I use MN19TYG03 as a direct replacement in existing designs? A: Substitution feasibility depends on mechanical mounting compatibility and circuit requirements specific to your application. Verify form factor and actuation mechanism compatibility with your design specifications.
