Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTH-040-03-L-D-DP-A-TR is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Differential Pair Array, Male)
• Position count and row configuration (80 positions, 2 rows)
• Pitch specification (0.020" / 0.50mm)
• Contact material and finish (Gold, 10.0µin thickness)
• Mounting technology (Surface Mount)
• Mechanical envelope (11mm stacking height, 0.404" height above board)
• Compliance certifications (RoHS3, MSL 1)

The identified substitute part QTH-040-03-L-D-DP-A differs only in packaging configuration (Tray versus Tape & Reel). All electrical and mechanical parameters remain identical, making this part functionally interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the QTH-040-03-L-D-DP-A-TR and QTH-040-03-L-D-DP-A maintain active production status with full RoHS3 compliance and MSL 1 rating. Selection between these parts is determined by supply chain and assembly process requirements rather than electrical or mechanical performance.

The QTH-040-03-L-D-DP-A-TR in Tape & Reel packaging is suitable for high-volume automated assembly operations utilizing pick-and-place equipment. The QTH-040-03-L-D-DP-A in Tray packaging accommodates manual assembly processes or lower-volume production runs. Both configurations deliver identical component performance and board-level functionality.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically identical? A: Yes. Both parts feature identical contact configurations, pitch, row count, and gold plating specifications. Electrical performance and signal integrity characteristics are equivalent.

Q: Can I substitute the Tray-packaged part for the Tape & Reel version in production? A: Substitution is feasible at the component level. However, assembly process compatibility must be evaluated. Tape & Reel packaging integrates with automated pick-and-place systems, while Tray packaging requires manual handling or alternative feeder systems.

Q: Do packaging differences affect PCB footprint or mounting? A: No. Packaging configuration does not alter the component's physical footprint, pad layout, or mounting characteristics. PCB design and assembly procedures remain unchanged.

Q: Are both parts compliant with current regulations? A: Yes. Both parts carry ROHS3 compliance and MSL 1 rating, meeting current environmental and reliability standards.

Q: What is the significance of the 0.020" pitch specification? A: The 0.020" (0.50mm) pitch defines the center-to-center spacing between contact positions. This specification is critical for PCB footprint design and connector mating. Both parts maintain identical pitch.
