ICA-316-SST DIP Socket Equivalent & Substitute Parts

Part Overview

The ICA-316-SST is a 16-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting of dual inline package integrated circuits. This socket features gold-plated beryllium copper mating contacts with 0.100" (2.54mm) pitch and 0.3" (7.62mm) row spacing. The part is active in production and ROHS3 compliant. Equivalent and substitute parts are identified when electrical and mechanical parameters align with the original specification, enabling component interchangeability in circuit board designs.

Substitute Part Grouping Explanation

Substitute parts for the ICA-316-SST are qualified based on strict alignment of the following critical parameters:

Number of positions and row spacing (16 positions, 0.3" spacing)
Mating pitch and post pitch (0.100" for both)
Contact material and finish (beryllium copper with gold plating on mating side)
Mounting type (through-hole solder termination)
Termination post length (0.125")
RoHS compliance status
Moisture sensitivity level (MSL 1)

All identified substitutes maintain these core electrical and mechanical specifications, ensuring direct functional equivalence in circuit board applications. Variations in housing material, post contact finish thickness, or current rating do not affect substitutability when the primary contact interface parameters remain constant.

Engineering Selection Recommendations

Primary Substitutes (ROHS3 Compliant):

110-41-316-41-001000 (Mill-Max Manufacturing Corp.) and 110-87-316-41-001101 (Preci-Dip) are direct functional equivalents to the ICA-316-SST. Both maintain full ROHS3 compliance, identical mechanical dimensions, and beryllium copper mating contacts with gold finish. These parts are suitable for applications requiring full compliance with current environmental regulations.

16-3518-10 (Aries Electronics) is functionally equivalent with ROHS3 compliance. This part is supplied in bulk packaging rather than tube format, which may affect procurement and handling procedures.

AR 16-HZL-TT (Assmann WSW Components) differs in mating contact finish (tin instead of gold) and operates within a narrower temperature range (-40°C ~ 105°C versus -55°C ~ 125°C). This part is suitable for applications where the reduced temperature range is acceptable and tin contact finish is compatible with the circuit design.

Secondary Substitute (Non-Compliant):

110-91-316-41-001000 (Mill-Max Manufacturing Corp.) is functionally equivalent but carries RoHS non-compliant status. This part is suitable only for applications where RoHS compliance is not required or where legacy component specifications are maintained.

Frequently Asked Questions (FAQ)

Q: Can I use AR 16-HZL-TT as a direct replacement for ICA-316-SST?

A: AR 16-HZL-TT is mechanically and electrically compatible for most applications. However, it features tin mating contacts instead of gold and operates within -40°C ~ 105°C rather than -55°C ~ 125°C. Use this part only if your application does not require the extended temperature range or if tin contact finish is acceptable for your circuit design.

Q: What is the difference between tube and bulk packaging for 16-3518-10?

A: Tube packaging (used by Samtec, Mill-Max, Preci-Dip, and Assmann) provides organized component storage and handling. Bulk packaging (used by Aries) typically offers cost advantages for high-volume procurement but requires additional handling and organization procedures. The electrical and mechanical specifications are identical.

Q: Why is 110-91-316-41-001000 marked as RoHS non-compliant?

A: This part uses tin-lead solder on the termination posts, which contains lead and does not meet ROHS3 environmental standards. Use this part only in applications where RoHS compliance is not mandated or where legacy component specifications are explicitly required.

Q: Are all substitute parts rated for the same current?

A: No. The ICA-316-SST is rated for 1 A, while 110-41-316-41-001000, 16-3518-10, AR 16-HZL-TT, and 110-91-316-41-001000 are rated for 3 A. Higher current ratings do not affect substitutability; the part can safely handle applications designed for the original 1 A specification.

Q: What determines if a part is a valid substitute?

A: Valid substitutes maintain identical number of positions (16), row spacing (0.3"), mating and post pitch (0.100"), contact material (beryllium copper), mounting type (through-hole), and termination post length (0.125"). Variations in housing material, contact finish thickness, or current rating do not affect functional substitutability.
