TE Connectivity AMP Connectors 2-1571551-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-1571551-3 is a 14-position DIP socket with 0.3" (7.62mm) row spacing, gold-plated contacts, and through-hole solder termination. This component belongs to the Sockets for ICs, Transistors category and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-1571551-3 is determined by strict equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 14 (2 x 7)
• Type: DIP, 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Contact Material - Mating: Beryllium Copper
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C
• Termination Post Length: 0.125" (3.18mm)
• Housing Material: Polycyclohexylenedimethylene Terephthalate (PCT), Polyester

Both substitute parts listed below meet all mandatory matching parameters and are therefore electrically and mechanically compatible with the original TE Connectivity component.

Parameter Comparison

Engineering Selection Recommendations

Mill-Max 210-13-314-41-001000 is the primary substitute for the TE Connectivity 2-1571551-3. This part maintains active product status, is ROHS3 compliant, and features a closed frame design identical to the original component. The gold contact finish on both mating and post surfaces provides superior corrosion resistance and electrical performance consistency with the original specification.

Mill-Max 110-91-314-41-001000 is an alternative substitute with active product status. This part features an open frame design and tin-lead post finish, which differs from the original closed frame and gold post finish. The open frame configuration may affect mechanical stability in certain mounting orientations. Additionally, this part is RoHS non-compliant, which may restrict its use in applications subject to RoHS regulations.

For applications requiring strict compliance with RoHS directives and design continuity with the original closed frame architecture, the Mill-Max 210-13-314-41-001000 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 110-91-314-41-001000 be used as a direct replacement for the TE Connectivity 2-1571551-3?

A: The Mill-Max 110-91-314-41-001000 is electrically and mechanically compatible based on matching pin count, pitch, row spacing, and operating temperature range. However, it differs in frame design (open versus closed) and post contact finish (tin-lead versus gold). These differences may affect performance in applications with specific environmental or reliability requirements.

Q: What is the significance of the closed frame versus open frame design?

A: The closed frame design provides additional mechanical support and containment of the socket structure. The open frame design offers reduced material and cost but may provide less mechanical stability. Both designs accommodate the same 14-position DIP package with 0.3" row spacing.

Q: Are there RoHS compliance differences between the substitute parts?

A: Yes. The Mill-Max 210-13-314-41-001000 is ROHS3 compliant, while the Mill-Max 110-91-314-41-001000 is RoHS non-compliant. Applications subject to RoHS regulations must use the 210-13-314-41-001000 variant.

Q: How do the contact finish specifications differ between the parts?

A: The TE Connectivity 2-1571551-3 features gold flash finish on mating contacts and gold flash finish on posts. The Mill-Max 210-13-314-41-001000 provides 30.0µin (0.76µm) gold on mating contacts and 10.0µin (0.25µm) gold on posts. The Mill-Max 110-91-314-41-001000 provides 10.0µin (0.25µm) gold on mating contacts and tin-lead finish on posts. These variations affect long-term corrosion resistance and contact reliability.

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

A: Yes. All three parts operate across the -55°C to 125°C temperature range, ensuring thermal compatibility in equivalent applications.

Q: What is the packaging difference between the main part and substitutes?

A: The TE Connectivity 2-1571551-3 packaging is not specified in the provided data. Both Mill-Max substitutes are supplied in tube packaging, which is standard for DIP socket components.
