Aries Electronics 28-516-10 DIP ZIF Socket - Equivalent & Substitute Parts

Part Overview

The Aries Electronics 28-516-10 is a 28-position DIP ZIF (Zero Insertion Force) socket with tin contact finish, designed for through-hole mounting of dual inline package integrated circuits. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The socket features a closed frame design with beryllium copper contacts and polyamide housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 28-516-10 is determined by the following critical parameters:

• Position Count & Grid: 28 positions (2 x 14) configuration
• Socket Type: DIP, ZIF (ZIP) mechanism
• Pitch - Mating: 0.100" (2.54mm) standard spacing
• Contact Material: Beryllium Copper
• Mounting Type: Through Hole
• Housing Material: Polyamide (PA46), Nylon 4/6, Glass Filled
• Termination Method: Solder
• Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 Compliant

The 28-516-10 has two identified substitutes within the Aries Electronics product line: 28-516-11 and 28-526-10. Both maintain the core mechanical and electrical specifications required for DIP socket functionality while offering variations in contact finish and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

28-516-11 Substitution: The 28-516-11 is an active product within the same 516 series, maintaining identical mechanical dimensions and electrical specifications as the 28-516-10. The primary difference is the contact finish: gold plating instead of tin. Both parts are ROHS3 compliant and REACH unaffected. Selection of 28-516-11 is appropriate for applications where gold contact finish is preferred for enhanced corrosion resistance or contact reliability.

28-526-10 Substitution: The 28-526-10 represents the Lo-PRO®file series variant, offering a reduced termination post length of 0.105" (2.67mm) compared to the standard 0.150" (3.81mm) of the 28-516-10. This part also provides an increased current rating of 3 A versus 1 A, and includes an operating temperature specification of -55°C to 105°C. The 28-526-10 maintains tin contact finish and full ROHS3 compliance. Selection of 28-526-10 is appropriate for space-constrained PCB layouts or applications requiring higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can the 28-516-11 be used as a direct replacement for the 28-516-10?

A: Yes. The 28-516-11 maintains identical position count (28), pitch (0.100"), mounting type (through hole), and termination post length (0.150"). The contact finish difference (gold vs. tin) does not affect mechanical compatibility. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the primary difference between the 28-516-10 and 28-526-10?

A: The 28-526-10 features a reduced termination post length (0.105" vs. 0.150"), higher current rating (3 A vs. 1 A), and includes an operating temperature range specification (-55°C to 105°C). Both maintain the same 28-position DIP ZIF configuration and tin contact finish.

Q: Is the 28-526-10 suitable for PCB designs originally specified for the 28-516-10?

A: The 28-526-10 is mechanically compatible for through-hole mounting and maintains the same mating pitch and position count. However, the reduced post length (0.105" vs. 0.150") may affect PCB hole depth requirements. Verify PCB design specifications before substitution.

Q: Are all three parts RoHS compliant?

A: Yes. The 28-516-10, 28-516-11, and 28-526-10 are all ROHS3 compliant and REACH unaffected.

Q: Why is the 28-516-10 listed as obsolete?

A: The 28-516-10 has been superseded by active products within the Aries Electronics portfolio. The 28-516-11 and 28-526-10 provide equivalent or enhanced functionality and are recommended for new designs and ongoing production.

Q: What is the significance of the contact finish material (tin vs. gold)?

A: Both tin and gold finishes are applied over beryllium copper base material at 10.0µin (0.25µm) thickness. Gold provides enhanced corrosion resistance and contact reliability in demanding environments, while tin is suitable for standard applications. Selection depends on application requirements and environmental conditions.
