• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 10.0µin (0.25µm)
• Mated Stacking Heights: 11mm
• Height Above Board: 0.265" (6.73mm)
• Features: Board Guide, Ground Bus (Plane), Shielded
• Series: Q2™ QMSS
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part QMSS-026-01-L-D-EM2 maintains identical electrical and mechanical specifications across all critical parameters, ensuring direct functional equivalence within the Q2™ QMSS connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the QMSS-026-06.75-L-D-A-GP and QMSS-026-01-L-D-EM2 are Active products from Samtec Inc. with full ROHS3 compliance and MSL 1 rating. The parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on inventory availability and supply chain requirements, as both parts meet identical performance and compliance criteria for rectangular connector applications requiring 52-position, 0.025" pitch surface mount headers with gold-plated contacts and shielded features.

Frequently Asked Questions (FAQ)

Q: Are QMSS-026-06.75-L-D-A-GP and QMSS-026-01-L-D-EM2 directly interchangeable?

A: Yes. Both parts maintain identical electrical and mechanical specifications including position count, pitch, mounting type, contact finish, stacking height, and feature set. They are functionally equivalent within the Q2™ QMSS series.

Q: What determines substitution eligibility for this connector?

A: Substitution is valid when the alternative part maintains the same number of positions (52), pitch (0.025"), row configuration (2), mounting type (Surface Mount), contact finish (Gold at 10.0µin thickness), height above board (0.265"), mated stacking height (11mm), and feature set (Board Guide, Ground Bus, Shielded).

Q: Do both parts have the same compliance certifications?

A: Yes. Both QMSS-026-06.75-L-D-A-GP and QMSS-026-01-L-D-EM2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between these two part numbers?

A: The parts differ only in their internal configuration codes (06.75-L-D-A-GP versus 01-L-D-EM2), which do not affect the electrical or mechanical performance specifications provided for this connector category.

Q: Are there any packaging differences?

A: Both parts are supplied in Tray packaging with identical handling and storage requirements.
