Substitute Part Grouping Explanation

The QMSS-016-01-H-D-DP-EM2 has one identified parametric equivalent: QMSS-016-06.75-H-D-DP-A.

Substitution eligibility is determined by the following critical parameters:

• Connector Type: Differential Pair Array, Male
• Number of Positions: 32
• Pitch: 0.025" (0.64mm)
• Number of Rows: 2
• Mounting Type: Surface Mount
• Contact Finish: Gold at 30.0µin (0.76µm)
• Height Above Board: 0.265" (6.73mm)
• Mated Stacking Height: 11mm
• Features: Board Guide, Ground Bus (Plane), Shielded
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Both parts belong to the Q2™ QMSS series and maintain identical electrical and mechanical specifications. The difference in part number suffix reflects packaging or configuration variations that do not affect functional compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both QMSS-016-01-H-D-DP-EM2 and QMSS-016-06.75-H-D-DP-A are Active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on:

• Current inventory availability and lead time requirements
• Packaging configuration needs (Tray packaging available for both)
• Supply chain and procurement preferences
• Design documentation and qualification history with either part number

Both parts satisfy identical electrical and mechanical requirements for 32-position differential pair array applications with surface mount integration, gold contact finish, and shielded differential pair architecture.

Frequently Asked Questions (FAQ)

Q: Can QMSS-016-06.75-H-D-DP-A be used as a direct replacement for QMSS-016-01-H-D-DP-EM2?

A: Yes. Both parts are parametric equivalents with identical connector type, position count, pitch, mounting type, contact finish, height specifications, and shielding features. They are functionally interchangeable in applications designed for either part number.

Q: What determines whether a part qualifies as a substitute?

A: Substitution eligibility requires matching specifications across all critical parameters: connector type (Differential Pair Array, Male), 32 positions, 0.025" pitch, 2-row configuration, surface mount mounting, gold contact finish at 30.0µin thickness, 0.265" height above board, 11mm mated stacking height, board guide and shielded features, and ROHS3 compliance with MSL 1 rating.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, MSL 1 (Unlimited), EAR99 export classification, and HTSUS code 8536.69.4040.

Q: What is the difference between the part number suffixes?

A: The part number suffix variations reflect different packaging or configuration options within the Q2™ QMSS series. The electrical and mechanical specifications remain identical.

Q: Are both parts currently in active production?

A: Yes. Both QMSS-016-01-H-D-DP-EM2 and QMSS-016-06.75-H-D-DP-A maintain Active product status with current inventory availability.
