QMSS-032-06.75-L-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QMSS-032-06.75-L-D-DP-A-TR is a 64-position differential pair array connector manufactured by Samtec Inc. in the Q2™ QMSS series. This surface mount male connector features gold-plated contacts, board guide, ground bus plane, and shielding. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when packaging configuration differs while all electrical and mechanical parameters remain identical, enabling equivalent performance in applications where the original packaging is unavailable or inventory constraints exist.

Substitute Part Grouping Explanation

Substitution eligibility for the QMSS-032-06.75-L-D-DP-A-TR is determined by equivalence across the following critical parameters:

  • Connector type and gender (Differential Pair Array, Male)
  • Position count and row configuration (64 positions, 2 rows)
  • Contact pitch and spacing (0.025" / 0.64mm)
  • Surface mount mounting technology
  • Contact material and finish specifications (Gold, 10.0µin thickness)
  • Mechanical features (Board Guide, Ground Bus, Shielding)
  • Physical dimensions (11mm stacking height, 0.265" above board)
  • Compliance certifications (ROHS3, MSL 1)

Packaging configuration (Tape & Reel versus Tray) does not affect electrical or mechanical compatibility and represents the sole differentiator for identified substitutes.

Engineering Selection Recommendations

Both the QMSS-032-06.75-L-D-DP-A-TR and QMSS-032-06.75-L-D-DP-A maintain Active product status from Samtec Inc. and satisfy identical electrical, mechanical, and compliance requirements. Selection between these parts should be based on packaging requirements and supply chain availability.

The Tape & Reel (TR) packaging of the main part supports automated assembly processes, while the Tray packaging of the substitute accommodates manual handling or alternative assembly workflows. Both configurations deliver equivalent connector performance in differential pair array applications requiring 64-position, 0.025" pitch surface mount connectivity with gold contact finish and shielded construction.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically and mechanically identical? A: Yes. Both parts share identical connector type, position count, pitch, mounting technology, contact specifications, and physical dimensions. Substitution is valid from an electrical and mechanical standpoint.

Q: What is the only difference between these parts? A: Packaging configuration. The main part uses Tape & Reel (TR) packaging, while the substitute uses Tray packaging. This difference does not affect connector performance or compatibility.

Q: Can I use the Tray-packaged substitute in automated assembly? A: Tray packaging is designed for manual handling or alternative assembly processes. Automated pick-and-place equipment typically requires Tape & Reel packaging. Verify your assembly process requirements before substitution.

Q: Do both parts meet the same compliance standards? A: Yes. Both parts are ROHS3 compliant, carry MSL 1 rating (Unlimited moisture sensitivity), and share identical ECCN and HTSUS classifications.

Q: Is there an inventory difference between these parts? A: Yes. The main part (QMSS-032-06.75-L-D-DP-A-TR) has 875 pcs in stock, while the substitute (QMSS-032-06.75-L-D-DP-A) has 802 pcs in stock. Availability may vary by supplier and time.
