Substitute Part Grouping Explanation

Substitution for the HSEC8-125-01-S-DV-A-L2-K is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is HSEC8-125-01-S-DV-A-L2-K-TR, which maintains identical specifications across all critical dimensions and performance characteristics. The sole difference between these parts is packaging format: the main part number is supplied in Tray packaging, while the substitute is supplied in Tape & Reel (TR) format.

Substitution eligibility is based on the following invariant parameters:

  • 50-position configuration with dual-edge, dual-read architecture
  • 0.031" (0.80mm) pitch spacing
  • 0.062" (1.57mm) card thickness tolerance
  • Female gender with cantilever contact type
  • Beryllium copper contacts with 30.0µin gold finish
  • Surface mount solder termination
  • -55°C to 125°C operating temperature range
  • Liquid Crystal Polymer insulation
  • RoHS3 and MSL Level 1 compliance

Engineering Selection Recommendations

Both the HSEC8-125-01-S-DV-A-L2-K and HSEC8-125-01-S-DV-A-L2-K-TR are active products with full RoHS3 compliance and MSL Level 1 rating. Selection between these parts should be based on assembly process requirements and supply chain logistics. The Tray-packaged variant is suitable for manual assembly or lower-volume production runs, while the Tape & Reel format is optimized for automated pick-and-place assembly operations. Both variants are electrically and mechanically identical and will perform identically in the target application. Inventory availability may also influence selection, as the Tape & Reel variant currently shows higher stock levels (1414 pcs vs. 1127 pcs).

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. The HSEC8-125-01-S-DV-A-L2-K and HSEC8-125-01-S-DV-A-L2-K-TR are electrically identical. All contact materials, finishes, pitch spacing, and electrical performance characteristics are identical.

Q: What is the only difference between these part numbers? A: The packaging format. The base part number uses Tray packaging, while the -TR suffix indicates Tape & Reel packaging. The connector itself is identical.

Q: Can I use the Tape & Reel version in manual assembly? A: Yes. While Tape & Reel packaging is optimized for automated assembly, the connectors can be manually extracted and used in manual assembly processes.

Q: Are both parts RoHS3 compliant? A: Yes. Both variants maintain full RoHS3 compliance and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which packaging should I specify for my design? A: Specify based on your manufacturing process. Use Tray for manual or semi-automated assembly. Use Tape & Reel for fully automated pick-and-place operations.

Q: Do these parts require different PCB footprints? A: No. Both parts use identical footprints and mounting specifications. PCB design files do not require modification when switching between packaging variants.
