QSS-050-01-L-D-A-TR Equivalent & Substitute Parts

Part Overview

The QSS-050-01-L-D-A-TR is a 100-position rectangular connector socket manufactured by Samtec Inc. as part of the Q Strip® QSS series. This surface mount component features center strip contacts with gold plating and is designed for high-density interconnect applications. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when packaging or inventory requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the QSS-050-01-L-D-A-TR is limited to packaging format variations. The primary substitution criterion is the transition from Tape & Reel (TR) packaging to Tray packaging. Both the main part and substitute maintain identical electrical and mechanical specifications:

• Connector type, position count, and pitch
• Surface mount mounting configuration
• Gold contact finish and thickness
• Board guide and ground bus features
• RoHS3 compliance and MSL 1 rating
• Mated stacking height and height above board

The only distinction between QSS-050-01-L-D-A-TR and QSS-050-01-L-D-A is the packaging method, which affects handling, storage, and supply chain logistics but does not alter component functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both QSS-050-01-L-D-A-TR and QSS-050-01-L-D-A are active production components with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is determined by packaging requirements and supply chain considerations rather than functional performance. The Tape & Reel format (TR) is optimized for automated assembly processes, while Tray packaging accommodates manual handling and alternative distribution channels. Both formats deliver components with equivalent electrical and mechanical performance for 100-position surface mount socket applications.

Frequently Asked Questions (FAQ)

Q: Can QSS-050-01-L-D-A (Tray) be used as a direct replacement for QSS-050-01-L-D-A-TR (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Tray packaging may require different handling procedures during assembly but does not affect component functionality.

Q: What is the primary difference between these two part numbers?

A: The suffix "-TR" indicates Tape & Reel packaging, while the absence of this suffix indicates Tray packaging. All other specifications, including connector configuration, contact materials, and compliance ratings, are identical.

Q: Are there any compatibility concerns when switching between packaging formats?

A: No compatibility concerns exist at the component level. However, assembly line equipment may require adjustment for different packaging formats. Verify that your pick-and-place equipment or manual assembly process can accommodate the selected packaging type.

Q: Do both parts meet the same compliance standards?

A: Yes. Both QSS-050-01-L-D-A-TR and QSS-050-01-L-D-A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) rating. Compliance certifications are identical.

Q: Which packaging format should I select for high-volume production?

A: Tape & Reel (TR) packaging is standard for automated assembly processes. Tray packaging is suitable for lower-volume applications or manual assembly workflows. Selection depends on your manufacturing process requirements, not component performance.
