Engineering Selection Recommendations

All substitute parts from the Amphenol ICC (FCI) BERGSTIK® II series maintain active product status, ensuring long-term availability and supply chain continuity. Each substitute meets UL94 V-0 flammability requirements and maintains MSL 1 (Unlimited) moisture sensitivity classification, matching the original Molex component's environmental specifications.

Gold-Plated Variants (68020-156HLF, 68020-256HLF, 68021-156HLF, 68021-256HLF): These parts provide gold or gold GXT™ mating contact finishes with 30.0µin or 15.0µin thickness, suitable for applications requiring enhanced corrosion resistance and signal integrity. The 68021 series variants include 110V voltage rating specification.

Tin-Plated Variants (68020-456HLF, 68021-456HLF): These parts feature tin mating and post contact finishes with 100.0µin thickness, appropriate for cost-sensitive applications where gold plating is not required. The 68021-456HLF variant includes 110V voltage rating specification.

Contact Post Length Consideration: The 68020 series provides 0.095" (2.41mm) post length, while the 68021 series provides 0.120" (3.05mm) post length. Selection depends on PCB thickness and solder joint requirements in the target application.

All substitute parts are RoHS compliant and suitable for automotive, medical, telecommunications, and general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 68020 series part as a direct replacement for the Molex 0010892566?

A: Yes. The 68020 series maintains all critical compatibility parameters: 56 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole right-angle mounting, and push-pull fastening. The primary difference is contact post length (0.095" vs. 0.110"), which is acceptable for standard PCB applications.

Q: What is the difference between the 68020 and 68021 series?

A: The 68021 series provides longer contact posts (0.120" vs. 0.095") and includes a 110V voltage rating specification. Select 68021 for applications requiring thicker PCB accommodation or explicit voltage rating documentation.

Q: Should I choose gold-plated or tin-plated contacts?

A: Gold-plated variants (156HLF, 256HLF) provide superior corrosion resistance and are recommended for high-reliability applications in automotive, medical, and telecommunications. Tin-plated variants (456HLF) are suitable for general-purpose applications where cost optimization is prioritized.

Q: What does the contact finish thickness variation mean?

A: Contact finish thickness affects durability and mating cycle life. The 30.0µin (0.76µm) thickness matches the original Molex specification. The 15.0µin (0.38µm) variant provides thinner plating for cost reduction, while 100.0µin (2.54µm) provides maximum durability for high-cycle applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Amphenol ICC (FCI) BERGSTIK® II variants are RoHS compliant. The original Molex part is ROHS3 compliant. Verify REACH status requirements for your specific application, as some variants are REACH Affected.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are in active production with current stock availability: 68020-156HLF (893 pcs), 68020-256HLF (945 pcs), 68020-456HLF (615 pcs), 68021-156HLF (777 pcs), 68021-256HLF (853 pcs), 68021-456HLF (717 pcs).
