Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A20-LCG are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Number of Positions and Grid Configuration: 20 positions in 2 x 10 arrangement
• Row Spacing: 0.3" (7.62mm) center-to-center
• Mating Pitch: 0.100" (2.54mm)
• Contact Finish: Gold plating on mating contacts
• Mounting Type: Through hole solder termination
• Housing Material: PCT/Polyester construction
• Termination Post Pitch: 0.100" (2.54mm)

All substitute parts listed maintain these core electrical and mechanical parameters, ensuring direct compatibility in applications designed for the A20-LCG.

Parameter Comparison

Engineering Selection Recommendations

110-13-320-41-001000 (Mill-Max Manufacturing Corp.) is the recommended substitute for new designs and ongoing production. This part carries Active product status, ROHS3 compliance, and an extended operating temperature range of -55°C to 125°C compared to the TE Connectivity alternative. The Mill-Max part is available in higher inventory (1,048 units) and is supplied in tube packaging, supporting manufacturing automation requirements.

820-AG11D-ESL-LF (TE Connectivity AMP Connectors) is a functional equivalent with Obsolete product status. This part maintains full electrical and mechanical compatibility but carries a narrower operating temperature range (-55°C to 105°C) and RoHS Compliant status rather than ROHS3. Selection of this part should be limited to legacy system maintenance or applications where existing qualification data exists.

Both substitute parts satisfy the core electrical and mechanical requirements of the A20-LCG and are suitable for direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 110-13-320-41-001000 be used as a direct replacement for the A20-LCG?

A: Yes. Both parts share identical position count (20), row spacing (0.3"), mating pitch (0.100"), gold contact finish, through-hole mounting, and solder termination. The Mill-Max part is electrically and mechanically compatible for PCB assembly without design modification.

Q: What is the difference between the TE Connectivity and Mill-Max substitutes?

A: The primary differences are product status (TE Connectivity is Obsolete; Mill-Max is Active), operating temperature range (TE: -55°C to 105°C; Mill-Max: -55°C to 125°C), RoHS certification level (TE: RoHS Compliant; Mill-Max: ROHS3 Compliant), and inventory availability. Both maintain identical electrical and mechanical specifications for the socket interface.

Q: Are there packaging differences between these parts?

A: The Mill-Max 110-13-320-41-001000 is supplied in tube packaging, which supports automated pick-and-place assembly. Packaging information for the A20-LCG and TE Connectivity part is not specified in the available data.

Q: What parameters must remain constant for substitution compatibility?

A: The following parameters are non-negotiable for direct substitution: 20-position count in 2 x 10 configuration, 0.3" row spacing, 0.100" mating pitch, gold contact finish, through-hole solder termination, and PCT/polyester housing material. Any deviation in these parameters requires design re-qualification.

Q: Is the Mill-Max part suitable for high-temperature applications?

A: The Mill-Max 110-13-320-41-001000 supports operating temperatures up to 125°C, making it suitable for applications requiring extended thermal performance compared to the TE Connectivity alternative (105°C maximum).
