Frequently Asked Questions (FAQ)

Q: Can the Aries Electronics 40-6518-10 be used as a direct replacement for the TE Connectivity 5-1571552-2 in existing designs?

A: Yes. The 40-6518-10 maintains identical mechanical footprint, electrical pin configuration, pitch specifications (0.100" mating and post), termination post length (0.125"), and through-hole solder termination. Both parts accommodate 40-position DIP packages with 0.6" row spacing. The 3 A current rating and gold-plated mating contacts match the original specification.

Q: What is the difference between the Aries 40-6518-10 and 40-6518-11 variants?

A: The primary difference is the contact finish on the termination posts. The 40-6518-10 features tin-plated posts, while the 40-6518-11 features gold-plated posts. Both maintain identical mating contact specifications, current ratings (3 A), and mechanical dimensions. Selection depends on application requirements for post contact finish.

Q: Are there current rating differences between substitute options?

A: Yes. The Aries Electronics 40-6518-10, 40-6518-10H, 40-6518-10M, 40-6518-10T, 40-6518-11, and 40-6518-11H all support 3 A current rating, matching the original 5-1571552-2. The Mill-Max 110-43-640-41-001000 also supports 3 A. However, the Preci-Dip 110-83-640-41-001101 and Samtec ICA-640-SGT are limited to 1 A current rating. Applications requiring 3 A operation must select from the higher-rated options.

Q: Do all substitute parts support the same operating temperature range as the original?

A: No. The original 5-1571552-2 operates from -55°C to 105°C. The Mill-Max 110-43-640-41-001000, Preci-Dip 110-83-640-41-001101, and Samtec ICA-640-SGT extend the upper limit to 125°C. The Aries Electronics variants do not specify operating temperature. Applications requiring operation above 105°C should select from the extended-range options.

Q: What packaging formats are available for the substitute parts?

A: Packaging varies by manufacturer. Mill-Max 110-43-640-41-001000 is supplied in Tube packaging. Preci-Dip 110-83-640-41-001101 is supplied in Bulk packaging. All Aries Electronics variants (40-6518-10, 40-6518-10H, 40-6518-10M, 40-6518-10T, 40-6518-11, 40-6518-11H) are supplied in Bulk packaging. Samtec ICA-640-SGT is supplied in Tube packaging. Packaging selection should align with assembly process requirements and inventory management procedures.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification. The original 5-1571552-2 carries RoHS compliance. ROHS3 certification represents an enhanced compliance standard and is fully compatible with RoHS requirements.

Q: What is the contact material difference between the original and substitutes?

A: The original 5-1571552-2 uses Copper Alloy for both mating and post contacts. Most substitute parts use Beryllium Copper for mating contacts and Brass or Brass Alloy for post contacts. These material variations maintain electrical performance and contact resistance specifications while offering improved durability and spring characteristics in the substitute designs.

Q: Can I mix different substitute part numbers in the same assembly?

A: All identified substitute parts maintain identical mechanical footprint and electrical pin configuration, allowing interchangeability within a single assembly. However, design documentation should specify a single part number to ensure consistency in manufacturing, testing, and field service procedures.

Q: What is the contact resistance specification for all substitute parts?

A: The original 5-1571552-2 specifies 10mOhm contact resistance. The Preci-Dip 110-83-640-41-001101 and Samtec ICA-640-SGT also specify 10mOhm. The Mill-Max 110-43-640-41-001000 and Aries Electronics variants do not specify contact resistance values. Applications with critical contact resistance requirements should select from parts with published specifications.

Q: Are moisture sensitivity levels identical across all options?

A: Yes. The original 5-1571552-2 and all identified substitute parts carry MSL 1 (Unlimited) moisture sensitivity level classification. This indicates no moisture sensitivity and no special storage or handling requirements beyond standard industrial practices.
