Engineering Selection Recommendations
Primary Recommendation: 210-43-624-41-001000 (Mill-Max Manufacturing Corp.)
The Mill-Max 210-43-624-41-001000 is the closest functional equivalent to the obsolete TE Connectivity 4-1571551-8. This part maintains closed-frame construction, identical pitch specifications, and gold-plated mating contacts. The part is active, ROHS3 compliant, and available in tube packaging with 1220 units in stock. The primary difference is post contact finish (tin versus gold), which is acceptable for standard DIP socket applications. This part carries a 3 A current rating and 10mOhm contact resistance specification.
Secondary Recommendation: 110-43-624-41-001000 (Mill-Max Manufacturing Corp.)
The Mill-Max 110-43-624-41-001000 provides an open-frame alternative with identical electrical specifications and the highest inventory availability (2068 units). This part features gold-plated mating contacts with 30.0µin thickness, tin-plated posts, and full temperature range specification. The open-frame design offers cost efficiency while maintaining all critical electrical parameters. Current rating is 3 A.
Alternative Selections for Specific Requirements:
- 110-13-624-41-001000: Offers gold post finish with reduced contact finish thickness (10.0µin) for applications requiring minimal plating thickness.
- 110-13-624-41-801000: Includes integrated decoupling capacitor feature for noise suppression applications.
- 110-44-624-41-001000: Provides tin-plated mating contacts as an alternative to gold finish, with highest inventory (2240 units).
All recommended substitutes are manufactured by Mill-Max Manufacturing Corp., maintain active product status, and comply with ROHS3 and MSL 1 requirements. Selection should be based on specific application requirements regarding frame type, contact finish specifications, and decoupling capacitor integration.
Frequently Asked Questions (FAQ)
Q: Can the Mill-Max 210-43-624-41-001000 directly replace the TE Connectivity 4-1571551-8 in existing PCB designs?
A: Yes. Both parts share identical pitch specifications (0.100" mating and post), 24-position configuration, 0.6" row spacing, through-hole solder termination, and 0.125" post length. The primary difference is post contact finish (tin versus gold), which does not affect mechanical or electrical compatibility in standard DIP socket applications.
Q: What is the difference between closed-frame and open-frame DIP sockets?
A: Closed-frame sockets (such as 210-43-624-41-001000) feature a complete housing structure that provides additional mechanical support and shielding. Open-frame sockets (such as 110-43-624-41-001000) have a reduced housing footprint, offering cost efficiency and reduced board space. Both types maintain identical electrical performance and contact specifications for standard DIP integrated circuits.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All Mill-Max substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original TE Connectivity part.
Q: What does the decoupling capacitor feature in parts 110-13-624-41-801000 and 110-43-624-41-801000 provide?
A: The integrated decoupling capacitor provides on-socket noise suppression for high-frequency applications. This feature is optional and should be selected only when noise filtering at the socket level is required by the application design.
Q: How do contact finish specifications affect socket performance?
A: Contact finish thickness and material affect contact resistance, corrosion resistance, and wear characteristics. The specified ranges (10.0µin to 30.0µin for mating contacts, 10.0µin to 200.0µin for posts) are all acceptable for standard DIP socket applications. Selection should be based on application environment and contact cycling requirements.
Q: Can tin-plated post sockets be used in applications originally designed for gold-plated posts?
A: Yes. Tin-plated posts (200.0µin thickness) provide equivalent electrical performance and solder joint reliability compared to gold-plated posts in standard through-hole PCB assembly. The thicker tin plating (200.0µin) provides enhanced durability and corrosion resistance.
Q: What is the current rating specification for these DIP sockets?
A: Mill-Max substitute parts specify a 3 A current rating per contact. This rating is suitable for standard DIP integrated circuit applications. The original TE Connectivity part does not specify current rating in the provided data.
Q: Are there packaging differences between substitute parts?
A: Yes. The 210-43-624-41-001000 is supplied in tube packaging. Most Mill-Max 110-series parts are supplied in tube packaging. Packaging format does not affect electrical or mechanical performance and is determined by procurement and assembly requirements.
Q: Which substitute part offers the best inventory availability?
A: The Mill-Max 110-44-624-41-001000 offers the highest inventory availability with 2240 units in stock. The 110-43-624-41-001000 provides the second-highest availability with 2068 units. Both parts are suitable for immediate procurement needs.
