Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1571552-3 is determined by the following critical parameters that must remain consistent across equivalent parts:

Mandatory Matching Parameters:

• Number of Positions: 14 (2 x 7)
• Type: DIP with 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Termination Post Length: 0.125" (3.18mm)
• Contact Material - Mating: Beryllium Copper
• Features: Open Frame

Allowable Variations:

• Contact Finish - Mating: Tin or Gold (both acceptable for DIP socket applications)
• Contact Material - Post: Copper or Brass Alloy (both acceptable for solder termination)
• Housing Material: PCT Polyester or Polyamide (PA46) Nylon 4/6 Glass Filled (both acceptable)
• Operating Temperature Range: Substitute parts with -55°C ~ 125°C exceed the original -55°C ~ 105°C specification and are acceptable
• Product Status: Active substitutes are preferred over obsolete status

All substitute parts listed maintain electrical and mechanical compatibility with the original 1571552-3 connector.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, providing superior long-term availability compared to the obsolete 1571552-3. Selection among substitutes is based on the following criteria:

Direct Tin-Finish Equivalent: The 110-44-314-41-001000 (Mill-Max Manufacturing) maintains the original tin contact finish on the mating surface, providing the closest electrical and material match to the 1571552-3. This part is ROHS3 compliant and rated for -55°C ~ 125°C operation, exceeding the original temperature specification.

Gold-Finish Alternatives: All remaining substitutes feature gold contact finish on the mating surface, which provides enhanced corrosion resistance and contact reliability compared to tin. These parts are suitable for applications requiring improved long-term performance in varied environmental conditions. The gold-finish options include:

• Mill-Max 101-93-314-41-560000, 110-41-314-41-001000, 110-43-314-41-001000, 110-43-314-41-801000, and 111-43-314-41-001000
• Aries Electronics 14-3518-10, 14-3518-101H, 14-3518-10E, and 14-3518-10H

Special Consideration: The 110-43-314-41-801000 includes an integrated decoupling capacitor feature, which may provide additional circuit benefits in applications requiring noise suppression on the socket connection.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1571552-3 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain the critical mechanical and electrical parameters: 14-position DIP configuration, 0.3" row spacing, 0.100" pitch, through-hole solder termination, and 0.125" post length. The primary differences are contact finish material (tin versus gold) and manufacturer, both of which are allowable variations for DIP socket applications.

Q: What is the difference between tin and gold contact finishes?

A: The 1571552-3 features tin contact finish on the mating surface. The 110-44-314-41-001000 provides an equivalent tin finish. Gold-finish alternatives (all other substitutes) offer enhanced corrosion resistance and improved contact reliability, particularly in applications with extended storage periods or exposure to corrosive environments. Both finishes are electrically compatible with standard 14-pin DIP integrated circuits.

Q: Are there packaging differences among the substitutes?

A: Yes. The Aries Electronics parts (14-3518 series) are available in bulk packaging, while most Mill-Max parts are supplied in tube packaging. The 101-93-314-41-560000 does not specify packaging type. Packaging selection should be based on procurement and assembly requirements rather than electrical performance.

Q: Does the operating temperature range difference affect compatibility?

A: The 1571552-3 is rated for -55°C ~ 105°C operation. All substitute parts are rated for -55°C ~ 125°C, which exceeds the original specification. This represents an improvement and does not create compatibility issues. Applications operating within the original -55°C ~ 105°C range will function identically with any substitute part.

Q: What is the significance of the decoupling capacitor feature in the 110-43-314-41-801000?

A: The 110-43-314-41-801000 includes an integrated decoupling capacitor within the socket structure. This feature provides localized noise suppression on the socket connection. Applications that do not require this feature can use any other substitute without functional difference. Applications that benefit from integrated decoupling should specify this part number.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements. The original 1571552-3 is RoHS compliant (earlier standard). ROHS3 compliance ensures compatibility with modern manufacturing and procurement standards.

Q: What is the contact resistance specification for the substitutes?

A: The original 1571552-3 specifies 10 mOhm contact resistance. The Mill-Max and Aries Electronics substitutes do not provide contact resistance specifications in the available data. However, all parts utilize beryllium copper mating contacts with identical geometry and pitch, ensuring equivalent electrical performance for standard DIP socket applications.

Q: Can the 1571552-3 be used interchangeably with the substitutes in existing designs?

A: Yes. The mechanical footprint, pin configuration, and electrical characteristics are identical across all listed parts. Existing PCB designs and component layouts require no modification. The substitutes can be used as direct replacements in new production runs or repair applications.
