Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Highest Compatibility):

The Mill-Max Manufacturing Corp. 210-43-314-41-001000 and 605-43-314-11-480000 provide the closest functional equivalence to the 4-1571551-3. Both maintain the specified operating temperature range of -55°C to 125°C, contact resistance of 10mOhm, and UL94 V-0 flammability rating. The 210-43-314-41-001000 features a closed frame configuration matching the original design, while the 605-43-314-11-480000 incorporates a carrier with open frame design suitable for low-profile applications. Both are ROHS3 compliant and currently in active production status.

Compatible Alternatives (Functional Equivalence):

The Aries Electronics 14-3518 series (14-3518-10, 14-3518-10E, 14-3518-10H, 14-3518-10M, 14-3518-10T, 14-3518-11, and 14-3518-11H) provide functional equivalence with the following considerations: These parts feature open frame construction and polyamide housing material, differing from the original closed frame PCT polyester design. Operating temperature specifications are not provided for Aries parts. The 14-3518-10 variants employ tin-plated posts, while 14-3518-11 and 14-3518-11H feature gold-plated posts. All Aries parts carry UL94 V-0 flammability rating and ROHS3 compliance with 3 A current rating.

Selection Criteria:

For applications requiring exact thermal performance specification, select Mill-Max 210-43-314-41-001000 or 605-43-314-11-480000. For applications where frame configuration and housing material are non-critical, Aries Electronics 14-3518 series parts provide cost-effective alternatives. All substitute parts maintain the critical 14-position DIP configuration, 0.100" (2.54mm) pitch, gold-plated mating contacts, and through-hole solder termination required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the Aries Electronics 14-3518 series parts directly replace the TE Connectivity 4-1571551-3?

A: Yes, with design considerations. The Aries parts maintain all critical electrical parameters: 14-position DIP configuration, 0.100" (2.54mm) pitch, beryllium copper mating contacts with gold plating, and 0.125" (3.18mm) solder post length. Differences include open frame versus closed frame construction and polyamide housing versus PCT polyester. These differences do not affect electrical function in standard DIP socket applications.

Q: What is the difference between the 14-3518-10 and 14-3518-11 variants?

A: The primary difference is post contact finish. The 14-3518-10 series (including 14-3518-10E, 14-3518-10H, 14-3518-10M, 14-3518-10T) features tin-plated posts with 200.0µin (5.08µm) thickness. The 14-3518-11 and 14-3518-11H feature gold-plated posts with 10.0µin (0.25µm) thickness. Both configurations are compatible with standard solder termination processes.

Q: Why does the Mill-Max 605-43-314-11-480000 have a carrier feature?

A: The carrier design in the 605-43-314-11-480000 provides a low-profile socket configuration, reducing overall assembly height. This feature is beneficial for space-constrained applications while maintaining the same electrical and mechanical compatibility as standard DIP sockets.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The original 4-1571551-3 is RoHS Compliant. All active substitute parts meet current RoHS3 requirements, ensuring regulatory alignment for new designs and production.

Q: What is the significance of the contact finish thickness differences?

A: Contact finish thickness affects durability and wear resistance. The original 4-1571551-3 specifies 25.0µin (0.63µm) mating contact finish. Mill-Max parts provide 30.0µin (0.76µm), offering enhanced durability. Aries parts provide 10.0µin (0.25µm), which remains within acceptable parameters for standard insertion cycles. Selection depends on application insertion cycle requirements.

Q: Can I use the 605-43-314-11-480000 in place of a standard 14-3518 socket?

A: Yes. The 605-43-314-11-480000 maintains the same electrical specifications and pin configuration. The carrier feature provides additional mechanical support and reduced profile height. This part is suitable for applications where standard socket height is a constraint.

Q: What packaging options are available for these substitute parts?

A: Mill-Max parts are supplied in tube packaging. Aries Electronics 14-3518 series parts are available in bulk packaging. Tube packaging provides organized component handling, while bulk packaging offers cost efficiency for high-volume applications. Packaging selection does not affect electrical or mechanical performance.

Q: Is operating temperature specification critical for my application?

A: If your application operates across the full -55°C to 125°C range, select Mill-Max 210-43-314-41-001000 or 605-43-314-11-480000, which explicitly specify this temperature range. Aries Electronics parts do not provide operating temperature specifications. For applications operating within standard industrial ranges (0°C to 70°C), all substitute parts are suitable.
