Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A22-LCG are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Number of Positions or Pins (Grid): 22 (2 x 11)
• Type: DIP, 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Contact Material - Mating: Beryllium Copper
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 3 A
• Operating Temperature: -55°C ~ 125°C

The identified substitutes are manufactured by Mill-Max Manufacturing Corp. and maintain identical electrical and mechanical specifications across all critical parameters. Both substitute parts are active products with full RoHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Both Mill-Max substitute parts (110-13-322-41-001000 and 612-13-322-41-001000) are active products with full RoHS3 compliance and REACH unaffected status. The primary distinction between the two substitutes is the termination post length: 110-13-322-41-001000 features 0.125" (3.18mm) post length, while 612-13-322-41-001000 features 0.124" (3.15mm) post length. This 0.01" (0.25mm) difference may be relevant for specific PCB design requirements. The 110-13-322-41-001000 variant offers higher current inventory availability at 986 units. Selection between substitutes should be based on PCB hole depth specifications and immediate availability requirements.

Frequently Asked Questions (FAQ)

Q: What makes these parts functionally equivalent to the A22-LCG?

A: All three parts share identical critical specifications: 22-position DIP configuration, 0.3" (7.62mm) row spacing, 0.100" (2.54mm) mating pitch, gold contact finish, through-hole mounting, and solder termination. These parameters define the mechanical and electrical compatibility for standard DIP socket applications.

Q: Are there any differences in contact materials between the main part and substitutes?

A: The Mill-Max substitutes specify beryllium copper for mating contacts and brass alloy for post contacts. The A22-LCG contact materials are not specified in the provided data. Both materials are standard for DIP socket applications and provide equivalent performance characteristics.

Q: What is the significance of the termination post length difference between the two Mill-Max substitutes?

A: The 110-13-322-41-001000 has 0.125" (3.18mm) post length, while the 612-13-322-41-001000 has 0.124" (3.15mm) post length. This 0.01" difference is within standard manufacturing tolerances but may affect fit in PCBs with specific hole depth specifications. Verify PCB design requirements before selection.

Q: Are both Mill-Max substitutes compliant with environmental regulations?

A: Yes. Both 110-13-322-41-001000 and 612-13-322-41-001000 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Which substitute should be selected for new designs?

A: Selection depends on PCB specifications and availability. The 110-13-322-41-001000 offers higher inventory (986 units) and longer post length (0.125"). The 612-13-322-41-001000 provides a slightly shorter post option (0.124"). Both are active products suitable for production use.
