Key Parameters

Substitute Part Grouping Explanation

The QMS-052-06.75-L-D-A-TR and QMS-052-06.75-L-D-A are functionally equivalent based on the following criteria:

Identical Parameters:

• Manufacturer: Samtec Inc.
• Series: Power Q2™ QMS
• Number of Positions: 104
• Pitch: 0.025" (0.64mm)
• Number of Rows: 2
• Connector Type: Header, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 10.0µin (0.25µm)
• Features: Board Guide, Ground Bus (Plane)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Base Product Number: QMS-052

Differentiating Factor: The primary difference is packaging: QMS-052-06.75-L-D-A-TR is supplied in Tape & Reel (TR) format, while QMS-052-06.75-L-D-A is supplied in Tray format. This distinction affects handling and storage but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both QMS-052-06.75-L-D-A-TR and QMS-052-06.75-L-D-A meet identical electrical and mechanical specifications for 104-position surface mount connector header applications. Selection between these parts should be based on:

Packaging Requirements: Choose QMS-052-06.75-L-D-A-TR for automated assembly processes requiring tape and reel format. Select QMS-052-06.75-L-D-A for manual assembly or applications where tray packaging is preferred.

Height Tolerance: Note the minor height above board difference (0.250" vs 0.265"). Verify PCB layout clearance if vertical space is constrained.

Compliance: Both parts are ROHS3 compliant and carry MSL 1 rating, suitable for unlimited shelf life storage without baking requirements.

Frequently Asked Questions (FAQ)

Q: Can QMS-052-06.75-L-D-A be used as a direct replacement for QMS-052-06.75-L-D-A-TR?

A: Yes, from an electrical and mechanical standpoint. The parts are functionally identical. The difference is packaging format (Tray vs. Tape & Reel). Verify your assembly process accommodates the tray format before substitution.

Q: What is the significance of the height above board difference between these parts?

A: QMS-052-06.75-L-D-A-TR has a height of 0.250" (6.35mm), while QMS-052-06.75-L-D-A measures 0.265" (6.73mm). This 0.015" (0.38mm) difference is minor but should be confirmed against PCB layout constraints, particularly in space-limited applications.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry ROHS3 compliance and MSL 1 rating. Compliance certifications are identical. Application suitability depends on your specific reliability requirements and environmental conditions, which should be evaluated against Samtec's published specifications.

Q: Does packaging format affect component performance?

A: No. Tape & Reel and Tray packaging formats do not alter electrical or mechanical performance. The choice is driven by assembly process requirements and inventory management practices.

Q: What is the base product number, and why is it relevant?

A: The base product number is QMS-052. This identifier groups all variants within the same connector family. Parts sharing the same base number maintain core design compatibility within their specified parameter ranges.
