Substitute Part Grouping Explanation

Substitute parts for the A18-LCG are identified based on strict electrical and mechanical parameter alignment:

Critical Matching Parameters:

• Number of Positions: 18 (2 x 9)
• DIP Type: 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Mounting Type: Through Hole
• Termination: Solder
• Housing Material: Polycyclohexylenedimethylene Terephthalate (PCT), Polyester

All identified substitutes meet these core parameters, ensuring mechanical and electrical compatibility with applications designed for the A18-LCG.

Parameter Comparison

Engineering Selection Recommendations

110-13-318-41-001000 (Mill-Max Manufacturing Corp.) is the primary recommended substitute for the A18-LCG. This part carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The Mill-Max socket is packaged in Tube format and maintains full electrical and mechanical compatibility with the original specification.

818-AG11D-ESL-LF (TE Connectivity AMP Connectors) is an alternative substitute with equivalent electrical and mechanical parameters. However, this part is classified as Obsolete, which may impact future procurement and long-term supply chain reliability. It carries RoHS Compliant certification and is available in current inventory.

Both substitutes maintain the critical 18-position DIP configuration with 0.3" row spacing, 0.100" pitch, gold-plated mating contacts, through-hole mounting, and solder termination required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: What determines if a socket can substitute for the A18-LCG? A: Substitutes must match the core mechanical and electrical parameters: 18-position DIP configuration, 0.3" (7.62mm) row spacing, 0.100" (2.54mm) mating pitch, gold contact finish, through-hole mounting type, and solder termination. These parameters ensure physical fit and electrical performance in applications designed for the A18-LCG.

Q: Are the Mill-Max and TE Connectivity sockets electrically identical to the A18-LCG? A: Both substitutes meet the specified electrical and mechanical requirements for 18-position DIP sockets with matching pitch, contact finish, and termination characteristics. They are functionally equivalent for applications requiring these socket specifications.

Q: What is the difference between the Mill-Max and TE Connectivity options? A: The Mill-Max 110-13-318-41-001000 carries Active product status and ROHS3 compliance, supporting long-term availability. The TE Connectivity 818-AG11D-ESL-LF is classified as Obsolete, which may affect future procurement options. Both meet the same electrical and mechanical specifications.

Q: Does packaging format affect compatibility? A: Packaging format (Tube for Mill-Max) does not affect the socket's electrical or mechanical performance. It relates only to handling, storage, and ordering quantities. The socket itself functions identically regardless of packaging.

Q: Are these substitutes suitable for new designs? A: The Mill-Max 110-13-318-41-001000 is recommended for new designs due to its Active status and current compliance certifications. The TE Connectivity part, while functionally equivalent, carries Obsolete status and may present supply chain constraints for future production.
