Frequently Asked Questions (FAQ)

Q: What makes a part a direct substitute for the 4-1571552-4?

A: A direct substitute must match all mandatory parameters: 16-position DIP configuration, 0.3" row spacing, 0.100" pitch for both mating and post, beryllium copper mating contacts with gold finish, through-hole solder termination, open frame design, 0.125" post length, and MSL 1 rating. The part must also be in active product status.

Q: Can I use a substitute with a different post contact material?

A: Yes. The original 4-1571552-4 uses copper post contacts with gold finish. Substitutes with tin-plated brass or brass alloy posts are functionally compatible due to equivalent electrical conductivity and solder joint reliability. Beryllium copper post contacts offer superior contact resistance (4mOhm versus 10mOhm) and are also acceptable.

Q: What is the significance of the operating temperature range difference?

A: The original part operates from -55°C to 105°C. Most active substitutes extend the upper limit to 125°C, providing additional thermal margin. The AR 16-HZL/07-TT has a lower upper limit of 105°C, matching the original specification. For applications operating within the original -55°C to 105°C range, all substitutes are suitable. For applications requiring operation above 105°C, select substitutes with 125°C upper limit.

Q: Why do some substitutes have different current ratings?

A: Current rating reflects the maximum continuous current the socket can safely carry. The original part does not specify a current rating. Substitutes rated at 1A or 3A are both acceptable for typical IC socket applications. The 3A rating provides additional margin for high-current applications.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant refers to the original Restriction of Hazardous Substances directive. ROHS3 Compliant refers to the updated directive (2011/65/EU as amended by 2015/863/EU) with additional restricted substances. For new designs, ROHS3 Compliant parts are preferred. The original 4-1571552-4 is RoHS Compliant; most active substitutes are ROHS3 Compliant.

Q: Can I use the 110-99-316-41-001000 with tin-lead mating contacts?

A: The 110-99-316-41-001000 features tin-lead mating contacts instead of gold. While mechanically compatible, this represents a material change that may affect contact reliability and corrosion resistance in certain environments. Use only if your application explicitly permits tin-lead mating contacts and has been validated for this material change.

Q: What is the difference between the Aries Electronics 16-3518-10, 16-3518-10E, and 16-3518-10H variants?

A: All three parts (16-3518-10, 16-3518-10E, and 16-3518-10H) share identical electrical and mechanical specifications. The suffix designations (base, E, and H) indicate packaging or internal design variations that do not affect functional performance. All are ROHS3 Compliant, active status, and directly interchangeable.

Q: Does the 110-93-316-41-801000 decoupling capacitor feature affect compatibility?

A: The integrated decoupling capacitor in the 110-93-316-41-801000 is an additional feature that does not interfere with standard IC socket operation. This part is mechanically and electrically compatible with the original 4-1571552-4. Select this variant only if the decoupling capacitor function is beneficial to your application.

Q: What packaging options are available for these substitutes?

A: Substitutes are available in Tube, Bulk, or unspecified packaging. Tube packaging provides organized component presentation suitable for automated assembly. Bulk packaging offers cost efficiency for high-volume applications. Packaging selection does not affect electrical or mechanical performance.

Q: Is the contact finish thickness variation significant?

A: The original 4-1571552-4 specifies 20.0µin (0.51µm) gold mating contact finish. Substitutes range from 10.0µin to 30.0µin (0.25µm to 0.76µm). All values within this range provide adequate corrosion protection and contact reliability. Thicker finishes (30.0µin) offer extended service life in harsh environments; thinner finishes (10.0µin) are suitable for standard applications.
