Substitute Part Grouping Explanation

The QMSS-016-06.75-L-D-DP-A-TR has one identified substitute: QMSS-016-06.75-L-D-DP-A. Substitution is valid based on the following criteria:

Identical Parameters:

• Manufacturer: Samtec Inc.
• Series: Q2™ QMSS
• 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
• Contact Finish Thickness: 10.0µin (0.25µm)
• Mated Stacking Height: 11mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameter:

• Packaging: QMSS-016-06.75-L-D-DP-A-TR uses Tape & Reel (TR); QMSS-016-06.75-L-D-DP-A uses Tray

The packaging difference does not affect connector interface compatibility or electrical/mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both QMSS-016-06.75-L-D-DP-A-TR and QMSS-016-06.75-L-D-DP-A are Active status products with identical ROHS3 compliance and EAR99 export classification. Selection between these parts is determined by packaging requirements:

• QMSS-016-06.75-L-D-DP-A-TR (Tape & Reel): Suitable for automated pick-and-place assembly processes requiring continuous reel feeding.
• QMSS-016-06.75-L-D-DP-A (Tray): Suitable for manual assembly or lower-volume production runs.

Both parts maintain identical connector interface specifications and are interchangeable from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Can QMSS-016-06.75-L-D-DP-A be used as a direct replacement for QMSS-016-06.75-L-D-DP-A-TR?

A: Yes. The connector interface, electrical characteristics, and mechanical specifications are identical. The only difference is packaging format (Tray vs. Tape & Reel). Substitution is valid provided assembly process compatibility with the tray packaging is confirmed.

Q: What is the significance of the height above board difference (0.265" vs. 0.250")?

A: The mated stacking height remains 11mm for both parts. The height above board measurement reflects the connector body profile in its unmated state. This minor difference does not affect interface compatibility or mating performance.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both QMSS-016-06.75-L-D-DP-A-TR and QMSS-016-06.75-L-D-DP-A are ROHS3 compliant, classified as EAR99, and carry HTSUS code 8536.69.4040. Both have MSL 1 rating (Unlimited moisture sensitivity level).

Q: Which part should be selected for high-volume automated assembly?

A: QMSS-016-06.75-L-D-DP-A-TR (Tape & Reel packaging) is optimized for automated pick-and-place equipment and continuous production workflows.

Q: Which part should be selected for low-volume or manual assembly?

A: QMSS-016-06.75-L-D-DP-A (Tray packaging) is suitable for manual assembly processes and lower-volume production requirements.
