Key Parameters

Substitute Part Grouping Explanation

The QTS-025-01-L-D-A-TR has one equivalent substitute part: QTS-025-01-L-D-A. Both parts share identical electrical and mechanical specifications across all critical parameters that determine functional compatibility:

• Number of positions: 50
• Pitch: 0.025" (0.64mm)
• Number of rows: 2
• Connector type: Header, Outer Shroud Contacts
• Mounting type: Surface Mount
• Contact finish: Gold at 10.0µin (0.25µm)
• Height above board: 0.160" (4.06mm)
• Mated stacking height: 5mm
• Features: Board Guide, Ground Bus (Plane)
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1

The only difference between these parts is the packaging format: QTS-025-01-L-D-A-TR is supplied in Tape & Reel format, while QTS-025-01-L-D-A is supplied in Tray format. This distinction affects procurement logistics and assembly line integration but does not alter the component's electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both QTS-025-01-L-D-A-TR and QTS-025-01-L-D-A are active production components manufactured by Samtec Inc. with full ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on packaging requirements and assembly process compatibility:

QTS-025-01-L-D-A-TR (Tape & Reel) is suitable for high-volume automated assembly operations utilizing pick-and-place equipment with tape feeder compatibility. This packaging format optimizes component handling efficiency in continuous production environments.

QTS-025-01-L-D-A (Tray) is suitable for manual assembly operations, lower-volume production runs, or assembly processes that do not utilize tape-based feeding systems. Tray packaging provides flexibility for mixed-component assembly workflows.

Both parts meet identical electrical and mechanical specifications and are interchangeable from a functional standpoint. The choice between them depends solely on manufacturing process requirements and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Are QTS-025-01-L-D-A-TR and QTS-025-01-L-D-A electrically and mechanically identical?

A: Yes. Both parts are functionally equivalent. They share identical specifications for position count, pitch, connector type, mounting method, contact finish, height, and all other electrical and mechanical parameters. The only difference is packaging format.

Q: Can I use QTS-025-01-L-D-A (Tray) in place of QTS-025-01-L-D-A-TR (Tape & Reel)?

A: From a component functionality standpoint, yes. However, assembly process compatibility must be evaluated. If your production line requires tape-fed components for automated pick-and-place equipment, the tray-packaged version requires manual feeding or alternative handling. Conversely, if your process uses manual assembly or tray-compatible feeders, the tape & reel version may require repackaging.

Q: What does the "-TR" suffix indicate?

A: The "-TR" suffix designates Tape & Reel packaging. Removal of this suffix indicates Tray packaging. All other designations in the part number remain identical between these two variants.

Q: Are both parts currently in production?

A: Yes. Both QTS-025-01-L-D-A-TR and QTS-025-01-L-D-A are active production components with current inventory availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection and full regulatory compliance for their respective applications.

Q: Which part should I specify for a new design?

A: Specify based on your manufacturing process requirements. For automated assembly with tape feeders, specify QTS-025-01-L-D-A-TR. For manual assembly or tray-compatible processes, specify QTS-025-01-L-D-A. Both are equally valid for new designs.
