Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-1571550-5 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 18 (2 x 9)
• Type: DIP with 0.3" (7.62mm) row spacing
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C

Secondary Compatibility Factors:

• Contact Finish - Mating: Gold (preferred for signal integrity and corrosion resistance)
• Contact Material - Mating: Beryllium Copper
• Pitch - Post: 0.100" (2.54mm)
• Termination Post Length: 0.125" (3.18mm)

All identified substitute parts meet the primary matching criteria. Variations in contact finish thickness, post material composition, and frame design (open versus closed) represent acceptable engineering trade-offs based on application requirements and compliance status.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications:

The Mill-Max 110-13-318-41-801000 and 110-44-318-41-001000, along with the Harwin D2818-42, satisfy ROHS3 compliance requirements. The 110-13-318-41-801000 provides gold-plated mating contacts with integrated decoupling capacitor functionality. The 110-44-318-41-001000 offers tin-plated mating contacts with increased thickness (100.0µin) for enhanced durability in high-cycle insertion applications. The Harwin D2818-42 delivers ROHS3 compliance with flash gold plating and UL94 V-0 flammability rating.

For Closed-Frame Applications:

The Mill-Max 210-93-318-41-001000 provides closed-frame construction matching the original TE Connectivity design, with UL94 V-0 flammability rating and 10mOhm contact resistance specification. This part is suitable for applications requiring mechanical shielding and structural rigidity, though RoHS non-compliance must be evaluated against regulatory requirements.

For Active Product Status:

All identified substitutes maintain active product status with established supply chains. The Mill-Max Series 110 and 210 parts offer higher inventory availability (858–1966 units) compared to the Harwin D2818-42 (971 units).

For Current Rating Considerations:

The Harwin D2818-42 specifies 1 A current rating, compared to 3 A for Mill-Max alternatives. Applications requiring current ratings exceeding 1 A should utilize Mill-Max substitutes.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 110-44-318-41-001000 (tin-plated) replace the TE Connectivity 2-1571550-5 (gold-plated)?

A: Yes. Both parts share identical mechanical and electrical specifications for the 18-position DIP socket configuration. The tin-plated mating contact finish (100.0µin thickness) provides equivalent electrical performance with enhanced wear resistance. Contact finish selection depends on application requirements for signal integrity and environmental exposure.

Q: What is the difference between open-frame and closed-frame DIP sockets?

A: Closed-frame sockets (TE Connectivity 2-1571550-5 and Mill-Max 210-93-318-41-001000) provide mechanical support and shielding around the perimeter of the socket cavity. Open-frame sockets (Mill-Max Series 110 and Harwin D2818-42) eliminate the outer frame structure, reducing material usage and cost while maintaining electrical functionality. Both designs accommodate standard 18-position DIP packages.

Q: Is the Harwin D2818-42 suitable for high-current applications?

A: The Harwin D2818-42 specifies a 1 A current rating, which is lower than the 3 A rating of Mill-Max alternatives. For applications requiring sustained currents above 1 A, Mill-Max Series 110 or 210 parts are appropriate selections.

Q: Which substitute part offers the best RoHS compliance status?

A: The Mill-Max 110-13-318-41-801000, Mill-Max 110-44-318-41-001000, and Harwin D2818-42 all carry ROHS3 Compliant status. The Mill-Max 110-91-318-41-001000, Mill-Max 110-93-318-41-001000, and Mill-Max 210-93-318-41-001000 are RoHS non-compliant due to tin-lead post plating.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts maintain identical pitch specifications (0.100" mating and post pitch) and termination post length (0.125" nominal, with D2818-42 at 0.126"). PCB footprints designed for the TE Connectivity 2-1571550-5 accommodate all identified substitutes without modification.

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

A: Contact finish thickness affects durability and insertion cycle life. The TE Connectivity 2-1571550-5 specifies 25.0µin (0.63µm) gold on mating contacts. Mill-Max alternatives range from 10.0µin to 100.0µin depending on series selection. Thicker finishes (100.0µin tin on 110-44-318-41-001000) provide extended wear life in high-cycle applications. Thinner finishes (10.0µin on 110-91-318-41-001000) reduce material cost while maintaining electrical specifications.

Q: Does the Mill-Max 110-13-318-41-801000 decoupling capacitor feature affect compatibility?

A: The integrated decoupling capacitor in the 110-13-318-41-801000 provides on-socket noise filtering without requiring additional discrete components. This feature does not affect mechanical or electrical compatibility with standard 18-position DIP packages. Applications not requiring decoupling functionality can utilize alternative Mill-Max or Harwin parts without performance impact.

Q: What packaging format is used for these substitute parts?

A: All identified substitute parts are supplied in tube packaging, consistent with standard DIP socket distribution methods. The TE Connectivity 2-1571550-5 packaging format is not specified in available documentation.
