Engineering Selection Recommendations

Primary Substitute: Amphenol ICC 68021-106HLF

The 68021-106HLF is the direct manufacturer equivalent from Amphenol ICC, representing the active-production successor to the obsolete 76350-104-06LF. Both components share identical pitch, position count, row configuration, and contact geometry. The 68021-106HLF offers active product status, RoHS compliance, and improved operating temperature range (-65°C ~ 125°C). This part is the preferred choice for direct replacement in existing designs.

Secondary Substitutes: Würth Elektronik 61300621021 and Samtec TSW Series

The Würth Elektronik 61300621021 and Samtec TSW-103-08 variants (TSW-103-08-G-D-RA, TSW-103-08-L-D-RA, TSW-103-08-T-D-RA) provide cross-manufacturer alternatives meeting all core substitution criteria. These parts maintain connector type, pitch, position count, and mounting configuration. Selection among these alternatives depends on specific application requirements regarding contact finish specifications and operating temperature ranges. All substitute parts carry active product status and current RoHS3 compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 68021-106HLF directly replace the 76350-104-06LF without PCB redesign?

A: Yes. Both parts share identical pitch (2.54mm), position count (6), row spacing (2.54mm), and mounting type (through-hole, right-angle). The 68021-106HLF maintains the same contact geometry and solder termination, enabling direct substitution on existing PCB layouts.

Q: What are the key differences between the Amphenol ICC and Samtec substitute options?

A: The primary differences are contact post length and insulation height. The Amphenol ICC 68021-106HLF maintains 0.120" post length and 0.190" insulation height, closely matching the original part. Samtec TSW-103-08 variants feature shorter post length (0.090") and taller insulation height (0.219"). These dimensional variations require verification against mating connector specifications and PCB layout constraints.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 68021-106HLF is RoHS Compliant. The Würth Elektronik 61300621021 and all Samtec TSW-103-08 variants are ROHS3 Compliant, meeting current regulatory requirements.

Q: Which substitute part offers the widest operating temperature range?

A: The Amphenol ICC 68021-106HLF and Samtec TSW-103-08-G-D-RA and TSW-103-08-L-D-RA all support -55°C ~ 125°C or -65°C ~ 125°C operating ranges. The Würth Elektronik 61300621021 operates at -40°C ~ 105°C, and the Samtec TSW-103-08-T-D-RA operates at -55°C ~ 105°C. Application thermal requirements should guide selection.

Q: What is the significance of contact finish variations among substitute parts?

A: Contact finish affects electrical performance and environmental resistance. The original part and most substitutes feature gold plating for superior corrosion resistance. The Samtec TSW-103-08-T-D-RA uses tin finish on both mating and post contacts, suitable for applications where gold plating is not required and cost optimization is prioritized.

Q: Are moisture sensitivity considerations different between substitute parts?

A: The Amphenol ICC 68021-106HLF, Samtec TSW-103-08 variants, and the original part all carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The Würth Elektronik 61300621021 is marked as Not Applicable for MSL, reflecting its polyamide insulation material. Both classifications are acceptable for standard handling and storage conditions.
