• Type: DIP with 0.6" (15.24mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Contact Material - Mating: Beryllium Copper
• Mounting Type: Through Hole
• Termination: Solder
• Termination Post Length: 0.125" (3.18mm)
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Contact Finish Thickness - Mating: Variation permitted (25.0µin to 30.0µin)
• Contact Finish - Post: Variation permitted (Gold or Tin)
• Contact Material - Post: Variation permitted (Nickel or Brass Alloy)
• Housing Material: Variation permitted (PCT Polyester or Polyamide PA46 Nylon)
• Frame Configuration: Variation permitted (Closed or Open Frame)
• Packaging: Variation permitted (Tube or Bulk)

Two substitute parts meet these criteria: Mill-Max Manufacturing Corp. 210-43-640-41-001000 (Direct Manufacturer Substitute) and Aries Electronics 40-6518-10 (Similar Manufacturer Substitute).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The TE Connectivity 5-1571551-2 serves as the primary reference part with established specifications.

Mill-Max Manufacturing Corp. 210-43-640-41-001000 functions as a direct manufacturer substitute. This part maintains identical critical parameters including 40-position DIP configuration, 0.6" row spacing, beryllium copper mating contacts with gold finish, and through-hole solder termination. The contact finish thickness on mating surfaces is slightly higher (30.0µin versus 25.0µin), and post contacts use tin finish with brass alloy material instead of gold-plated nickel. Both parts share PCT polyester housing material and identical operating temperature range. This substitute is packaged in tube format and carries 802 pieces in inventory.

Aries Electronics 40-6518-10 functions as a similar manufacturer substitute. This part maintains identical critical parameters for position count, row spacing, mating contact material and finish, and termination specifications. The mating contact finish thickness is lower (10.0µin), and post contacts use tin finish with brass material. The housing material differs, using polyamide PA46 nylon glass-filled composition instead of PCT polyester. The frame configuration is open rather than closed. Operating temperature range is not specified for this part. This substitute is packaged in bulk format and carries 2229 pieces in inventory.

Selection between these parts depends on specific application requirements regarding housing material composition, frame configuration, and contact finish thickness specifications. All three parts satisfy the core electrical and mechanical requirements for 40-position DIP socket applications.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 210-43-640-41-001000 be used as a direct replacement for the TE Connectivity 5-1571551-2?

A: Yes. Both parts share identical position count (40), row spacing (0.6"), mating contact material (beryllium copper with gold finish), mounting type (through-hole), and termination specifications (solder with 0.125" post length). The mating contact finish thickness variation (30.0µin versus 25.0µin) and post contact material difference (tin-plated brass versus gold-plated nickel) remain within allowable substitution parameters for DIP socket applications.

Q: What are the key differences between the Aries Electronics 40-6518-10 and the TE Connectivity 5-1571551-2?

A: The Aries part differs in three areas: housing material (polyamide PA46 nylon glass-filled versus PCT polyester), frame configuration (open frame versus closed frame), and mating contact finish thickness (10.0µin versus 25.0µin). The operating temperature range is not specified for the Aries part, whereas the TE Connectivity part specifies -55°C ~ 125°C. All other critical parameters including position count, row spacing, mating contact material, and termination specifications remain identical.

Q: Does the frame configuration difference between closed and open frame affect socket functionality?

A: Frame configuration affects mechanical structure and contact retention design. The TE Connectivity 5-1571551-2 and Mill-Max 210-43-640-41-001000 use closed frame design, while the Aries Electronics 40-6518-10 uses open frame design. Both configurations support the same electrical function and pin count. Selection depends on specific circuit board layout and mechanical assembly requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The TE Connectivity 5-1571551-2, Mill-Max 210-43-640-41-001000, and Aries Electronics 40-6518-10 all carry ROHS3 Compliant status. All three parts also maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

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

A: Contact finish thickness affects contact durability and wear resistance. The TE Connectivity part specifies 25.0µin (0.63µm) mating contact finish, the Mill-Max part specifies 30.0µin (0.76µm), and the Aries part specifies 10.0µin (0.25µm). These variations remain within acceptable ranges for DIP socket applications. Higher thickness generally provides extended contact life under repeated mating cycles.

Q: How do the packaging options affect part selection?

A: The TE Connectivity 5-1571551-2 packaging is not specified. The Mill-Max 210-43-640-41-001000 is supplied in tube packaging with 802 pieces in inventory. The Aries Electronics 40-6518-10 is supplied in bulk packaging with 2229 pieces in inventory. Packaging selection depends on assembly process requirements and volume needs. Tube packaging typically supports automated pick-and-place operations, while bulk packaging supports manual assembly or high-volume automated processes.

Q: Can the housing material difference between PCT polyester and polyamide PA46 nylon affect performance?

A: Housing material affects mechanical properties and environmental resistance. PCT polyester (used in TE Connectivity and Mill-Max parts) and polyamide PA46 nylon glass-filled (used in Aries part) both support the specified electrical function. Material selection depends on specific environmental conditions, mechanical stress requirements, and thermal cycling expectations in the application. Both materials carry UL94 V-0 flammability rating (TE Connectivity and Aries parts; Mill-Max rating not specified).

Q: Are all parts suitable for the same operating temperature range?

A: The TE Connectivity 5-1571551-2 and Mill-Max 210-43-640-41-001000 both specify -55°C ~ 125°C operating temperature range. The Aries Electronics 40-6518-10 does not specify an operating temperature range. Applications requiring confirmed temperature specifications should prioritize the TE Connectivity or Mill-Max parts.
