QTS-050-02-L-D-A-TR Equivalent & Substitute Parts

Part Overview

The QTS-050-02-L-D-A-TR is a 100-position rectangular connector header manufactured by Samtec Inc. as part of the Q Strip® QTS series. This surface mount connector features outer shroud contacts with gold plating and is designed for high-density interconnect applications requiring a 0.025" pitch configuration. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging or delivery format differs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the QTS-050-02-L-D-A-TR is determined by equivalence in the following critical parameters:

• Number of positions: 100
• Pitch configuration: 0.025" (0.64mm)
• Number of rows: 2
• Connector type: Header with outer shroud contacts
• Mounting type: Surface mount
• Contact finish: Gold at 10.0µin thickness
• Height above board: 0.278" (7.06mm)
• Mated stacking height: 8mm
• Features: Board guide and ground bus plane
• Series: Q Strip® QTS
• RoHS compliance: ROHS3
• Moisture sensitivity: Level 1

The substitute part QTS-050-02-L-D-A differs only in packaging format (Tray versus Tape & Reel). All electrical, mechanical, and environmental specifications remain identical. This substitution is valid when packaging requirements permit tray delivery instead of tape and reel format.

Parameter Comparison

Engineering Selection Recommendations

Both the QTS-050-02-L-D-A-TR and QTS-050-02-L-D-A are active production parts with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is determined solely by packaging requirements. The tape and reel format (TR suffix) is suitable for automated pick-and-place assembly operations. The tray format is suitable for manual assembly or alternative handling processes. Both parts meet identical electrical and mechanical specifications for the 100-position, 0.025" pitch connector header application. Inventory availability may also influence selection, with 933 units available in tape and reel format and 1047 units available in tray format.

Frequently Asked Questions (FAQ)

Q: Can QTS-050-02-L-D-A (Tray) be used as a direct replacement for QTS-050-02-L-D-A-TR (Tape & Reel)?

A: Yes, from an electrical and mechanical standpoint. Both parts are identical in all functional specifications. The difference is packaging format only. Compatibility depends on your assembly process requirements. Automated pick-and-place systems typically require tape and reel format, while manual assembly or alternative handling may accommodate tray format.

Q: Are there any performance differences between the two packaging formats?

A: No. The connector specifications, contact finish, pitch, position count, and all mechanical dimensions are identical. Packaging format does not affect electrical performance or mechanical fit.

Q: What is the significance of the "-TR" suffix?

A: The "-TR" suffix designates tape and reel packaging. Removal of this suffix indicates tray packaging. All other part number elements remain constant.

Q: Can I mix inventory from both packaging formats in the same production run?

A: This depends on your assembly process. If your equipment can handle both tape and reel and tray formats, mixing is possible. If your process is optimized for a single format, maintaining consistency is recommended.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QTS-050-02-L-D-A-TR and QTS-050-02-L-D-A carry ROHS3 compliance certification.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without special moisture control requirements. No baking or desiccant storage is necessary for either part.
