Frequently Asked Questions (FAQ)
Q: What are the critical parameters that determine if a part can substitute for the TE Connectivity 4-1571552-2?
A: The critical parameters are: 14-position configuration in 2 x 7 grid, 0.3" (7.62mm) row spacing, 0.100" (2.54mm) pitch for both mating and post contacts, beryllium copper mating contacts with gold finish, through-hole solder termination, and 0.125" (3.18mm) post length. These parameters ensure mechanical and electrical compatibility with existing PCB designs and IC packages.
Q: Can I use a part with tin-plated posts instead of gold-plated posts?
A: Parts with tin-plated posts (such as 110-43-314-41-001000, 110-83-314-41-001101, 14-3518-10, and ICA-314-SGT) are electrically compatible for solder termination. The post finish does not affect the mating contact interface with the IC package. However, design review is required if the original design specified gold posts for specific corrosion resistance or solderability requirements.
Q: What is the difference between direct substitutes and similar parts?
A: Direct substitutes meet all mechanical and electrical parameters with active product status and full compliance certifications. Similar parts meet core mechanical and electrical parameters but include variations in post contact finish, housing material composition, or compliance status that require design review before implementation.
Q: Does the operating temperature range difference affect substitution?
A: The original part specifies -55°C to 105°C. Most substitute parts extend this to -55°C to 125°C, which provides enhanced thermal capability. If the application operates within the original -55°C to 105°C range, the extended range of substitute parts does not create compatibility issues. However, if the application requires operation above 105°C, only substitute parts with extended temperature ratings are suitable.
Q: Are all substitute parts RoHS compliant?
A: Most substitute parts are ROHS3 compliant. However, 110-99-314-41-001000 and 111-93-314-41-001000 are RoHS non-compliant due to tin-lead post finishes. For applications requiring RoHS compliance, select only parts with ROHS3 compliant status.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in tube packaging (110-43-314-41-001000, 14-3518-10, ICA-314-SGT, 110-13-314-41-801000, 110-44-314-41-001000, 110-87-314-41-001101, 110-99-314-41-001000, 111-93-314-41-001000) and bulk packaging (110-83-314-41-001101). Packaging selection depends on production volume and inventory management requirements.
Q: How does the contact resistance specification affect part selection?
A: The original part specifies 10mOhm contact resistance. Substitute parts 110-83-314-41-001101, ICA-314-SGT, and the original part all specify 10mOhm. Other substitute parts do not specify contact resistance in available documentation. For applications with strict contact resistance requirements, select parts with documented 10mOhm specifications.
Q: Can I use a part with a different housing material?
A: The original part uses polycyclohexylenedimethylene terephthalate (PCT) polyester. Substitute parts use PCT polyester, PCT polyester with glass fill, or polyamide (PA46) nylon 4/6 with glass fill. Housing material differences do not affect electrical compatibility but may affect mechanical durability and thermal properties. Design review is required if the original design specified PCT polyester for specific mechanical or thermal performance.
Q: What is the significance of the UL94 V-0 flammability rating?
A: UL94 V-0 indicates the housing material meets the highest flammability classification, meaning it is self-extinguishing and does not propagate flame. The original part and most substitute parts (110-83-314-41-001101, 14-3518-10, ICA-314-SGT, 110-87-314-41-001101) carry this rating. Parts without specified flammability ratings (110-43-314-41-001000, 101-93-314-41-560000, 110-13-314-41-801000, 110-44-314-41-001000, 110-99-314-41-001000, 111-93-314-41-001000) require design review for applications with flammability requirements.
Q: What current rating should I select?
A: The original part does not specify a current rating. Substitute parts specify either 1 A (110-83-314-41-001101, ICA-314-SGT) or 3 A (110-43-314-41-001000, 14-3518-10, 101-93-314-41-560000, 110-13-314-41-801000, 110-44-314-41-001000, 110-99-314-41-001000, 111-93-314-41-001000). Current rating depends on the IC package and circuit requirements. Select parts with current ratings equal to or exceeding application requirements.
