Substitute Part Grouping Explanation

The 40-516-10 and 40-516-11 are functionally equivalent DIP ZIF sockets within the Aries Electronics 516 series. Substitution between these parts is determined by the following parameters that remain constant across both components:

• Number of positions: 40 (2 x 20)
• Pitch specifications: 0.100" (2.54mm) for both mating and post
• Contact material: Beryllium Copper
• Mounting type: Through Hole
• Termination method: Solder
• Current rating: 1 A
• Housing material: Polyamide (PA46), Nylon 4/6, Glass Filled
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The primary difference between these parts is the contact finish specification: the 40-516-10 uses tin finish, while the 40-516-11 uses gold finish. Both finishes maintain the same contact finish thickness of 10.0µin (0.25µm) and are applied to both mating and post contacts.

Parameter Comparison

Engineering Selection Recommendations

The 40-516-11 is the recommended substitute for the obsolete 40-516-10. Both components maintain identical mechanical and electrical specifications, with the exception of contact finish material. The 40-516-11 carries active product status and is ROHS3 compliant, supporting long-term design continuity and regulatory compliance. The gold contact finish of the 40-516-11 provides enhanced corrosion resistance compared to the tin finish of the 40-516-10, making it suitable for applications requiring extended shelf life or exposure to corrosive environments. Both parts are REACH unaffected and carry the same UL94 V-0 flammability rating, ensuring equivalent safety performance in end-use applications.

Frequently Asked Questions (FAQ)

Q: Can the 40-516-11 be used as a direct replacement for the 40-516-10?

A: Yes. Both parts share identical pin counts (40 positions), pitch specifications (0.100" / 2.54mm), mounting type (through-hole), and current ratings (1 A). The mechanical and electrical interfaces are fully compatible.

Q: What is the difference between the tin and gold contact finishes?

A: The 40-516-10 features tin contact finish, while the 40-516-11 features gold contact finish. Both maintain the same contact finish thickness of 10.0µin (0.25µm). Gold finish provides superior corrosion resistance and is preferred for applications with extended storage or exposure to corrosive environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the 40-516-10 and 40-516-11 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the 40-516-10 listed as obsolete?

A: The 40-516-10 has been superseded by the 40-516-11 within the Aries Electronics product line. The 40-516-11 is the active equivalent and is recommended for new designs and ongoing production.

Q: Are the housing materials identical between both parts?

A: Yes. Both parts use Polyamide (PA46), Nylon 4/6, Glass Filled housing material with UL94 V-0 flammability rating.

Q: What is the termination post length for these sockets?

A: Both the 40-516-10 and 40-516-11 have a termination post length of 0.150" (3.81mm), ensuring consistent PCB assembly compatibility.
