Engineering Selection Recommendations
Both QTS-050-03-L-D-A-TR and QTS-050-03-L-D-A are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and inventory availability. The Tape & Reel format (TR) is suitable for automated pick-and-place assembly operations, while the Tray format accommodates manual assembly or alternative handling processes. Both parts meet the same regulatory and environmental standards.
Frequently Asked Questions (FAQ)
Q: Can QTS-050-03-L-D-A be used as a direct replacement for QTS-050-03-L-D-A-TR?
A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. QTS-050-03-L-D-A-TR uses Tape & Reel packaging, while QTS-050-03-L-D-A uses Tray packaging. Component-level performance and board-level compatibility are identical.
Q: What is the primary consideration when choosing between these two parts?
A: Packaging format determines the selection. Tape & Reel (TR) format is optimized for automated assembly lines with pick-and-place equipment. Tray format is used for manual assembly, kit builds, or alternative handling methods. Verify your assembly process requirements before selecting.
Q: Are there any compliance or environmental differences between these parts?
A: No. Both parts carry ROHS3 compliance and have identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). They meet the same regulatory and environmental standards.
Q: Does packaging format affect the component's electrical performance?
A: No. Packaging is a logistics and assembly consideration only. Electrical specifications, contact resistance, signal integrity, and all functional parameters are identical between the two parts.
Q: What is the pitch specification for this connector?
A: The pitch is 0.025" (0.64mm), indicating the center-to-center distance between adjacent contact positions in the 100-position header.
