DIP628-001BLF Equivalent & Substitute Parts
Part Overview
The DIP628-001BLF is a 28-position DIP socket manufactured by Amphenol ICC (FCI) designed for IC and transistor applications. This through-hole socket features gold-plated mating contacts with beryllium copper material and tin-plated brass posts. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements. Substitute parts maintain the core electrical and mechanical specifications while offering active product status and improved availability.

Engineering Selection Recommendations
For RoHS3 Compliant Designs: 110-13-628-41-801000, 110-43-628-41-605000, 110-43-628-41-801000, 110-11-628-41-001000, 111-41-628-41-001000, and 115-41-628-41-001000 are all ROHS3 compliant and active products. These parts provide the most direct path for designs requiring regulatory compliance.
For Closest Electrical Match: 110-43-628-41-605000 and 110-43-628-41-801000 maintain identical mating contact finish thickness (30.0µin gold) and post finish (200.0µin tin) as the original DIP628-001BLF, with active product status and ROHS3 compliance.
For Standard Post Length (0.125"): All parts except 111-41-628-41-001000, 111-91-628-41-001000, and 115-41-628-41-001000 maintain the original 0.125" termination post length. These three alternatives feature extended (0.170") or reduced (0.108") post lengths and require PCB design verification.
For Non-Compliant Designs: 110-93-628-41-605000 and 110-93-628-41-801000 are active products with tin-lead post finish but are RoHS non-compliant. These are suitable only for applications without RoHS requirements.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with a different post length? A: Post length variations (0.108", 0.125", 0.170") affect PCB hole depth and solder joint formation. Substitutes with different post lengths require PCB design review to confirm compatibility with existing through-hole specifications and solder reflow profiles.
Q: What is the difference between gold and tin-lead post finishes? A: Gold post finishes (110-11-628-41-001000, 110-13-628-41-801000, 111-41-628-41-001000) provide superior corrosion resistance and are preferred for long-term reliability. Tin-lead finishes (110-93-628-41-605000, 110-93-628-41-801000, 111-91-628-41-001000) are traditional but non-RoHS compliant. Tin finishes (110-43-628-41-605000, 110-43-628-41-801000, 111-41-628-41-001000, 115-41-628-41-001000) offer a compliant middle ground.
Q: Are all substitute parts pin-compatible with the original DIP628-001BLF? A: Yes. All listed substitutes maintain 28 positions in a 2x14 configuration with 0.6" row spacing and 0.100" pitch, ensuring direct footprint compatibility.
Q: Which substitute offers the highest inventory availability? A: 110-13-628-41-801000 has the highest inventory at 1239 pieces, followed by 110-93-628-41-801000 at 1177 pieces.
Q: What is the significance of contact finish thickness? A: Mating contact finish thickness (10.0µin to 30.0µin gold) affects contact durability and wear resistance. Thicker finishes (30.0µin) provide extended service life in high-cycle applications. Post finish thickness (10.0µin to 300.0µin) influences solder joint strength and thermal cycling performance.
Q: Can I mix substitute parts from different manufacturers in the same design? A: All listed substitutes are manufactured by Mill-Max Manufacturing Corp. and maintain compatible electrical and mechanical specifications. However, assembly process validation is recommended when introducing new part numbers to production.
