Engineering Selection Recommendations

Both AXK7L40217G and AXK7L40227G are suitable direct replacements for the obsolete AXK7L40223G based on parametric equivalence. Selection between the two active alternatives should be based on:

Product Status: Both substitute parts are active products, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance: Both substitute parts carry RoHS Compliant certification, meeting current environmental and regulatory requirements for electronic component manufacturing and assembly.

Packaging Availability: Both alternatives are supplied in Tape & Reel (TR) format, standard for automated surface mount assembly processes.

Inventory Considerations: AXK7L40227G offers higher current stock levels (2230 pcs) compared to AXK7L40217G (711 pcs), which may influence procurement decisions based on project timelines and volume requirements.

Frequently Asked Questions (FAQ)

Q: Can AXK7L40217G and AXK7L40227G be used interchangeably with AXK7L40223G?

A: Yes. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting type, contact finish, and dimensional characteristics. They are parametric equivalents suitable for direct substitution.

Q: What is the primary reason for substituting the AXK7L40223G?

A: The AXK7L40223G is classified as obsolete. AXK7L40217G and AXK7L40227G are active products from the same manufacturer and series, providing assured long-term availability and supply chain reliability.

Q: Are there packaging differences between the main part and substitutes?

A: The main part packaging is not specified in the technical data. Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly and provides improved handling and placement efficiency.

Q: Do the substitute parts meet current environmental standards?

A: Yes. Both AXK7L40217G and AXK7L40227G are RoHS Compliant, meeting current environmental and regulatory requirements. The main part's RoHS status is not specified.

Q: How do the MSL ratings compare?

A: All three parts share an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching connector type, position count (40), pitch (0.016"/0.40mm), row configuration (2), mounting type (surface mount), contact finish (gold), solder retention feature, and dimensional specifications (0.9mm stacking height, 0.034" height above board).
