Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTH-040-02-H-D-DP-A-TR is determined by equivalence in the following critical parameters:

• Connector type and gender (Differential Pair Array, Male)
• Position count (80 positions)
• Pitch specification (0.020" / 0.50mm)
• Row configuration (2 rows)
• Surface mount mounting type
• Contact finish material and thickness (Gold, 30.0µin)
• Mechanical dimensions (stacking height, board height)
• Integrated features (Board Guide, Ground Bus)
• Compliance certifications (ROHS3)
• Moisture sensitivity rating (MSL 1)

The identified substitute part QTH-040-02-H-D-DP-A differs only in packaging format (Tray versus Tape & Reel). All electrical and mechanical specifications remain identical, making this part functionally equivalent for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

Both QTH-040-02-H-D-DP-A-TR and QTH-040-02-H-D-DP-A are active production parts with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is based solely on packaging and supply chain requirements. The Tape & Reel format (QTH-040-02-H-D-DP-A-TR) is suitable for automated assembly processes, while the Tray format (QTH-040-02-H-D-DP-A) accommodates manual handling and alternative distribution workflows. Both parts meet the same electrical and mechanical specifications for differential pair array connector applications.

Frequently Asked Questions (FAQ)

Q: Can QTH-040-02-H-D-DP-A be used as a direct replacement for QTH-040-02-H-D-DP-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Substitution is valid for component-level selection.

Q: What determines if a part can substitute for the QTH-040-02-H-D-DP-A-TR?

A: A substitute must maintain identical specifications in connector type, position count (80), pitch (0.020"), row configuration (2), mounting type (Surface Mount), contact finish (Gold, 30.0µin), mechanical dimensions, integrated features, and compliance ratings (ROHS3, MSL 1).

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Tray packaging formats do not alter the electrical or mechanical characteristics of the connector itself. Packaging selection is determined by assembly process requirements and supply logistics.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QTH-040-02-H-D-DP-A-TR and QTH-040-02-H-D-DP-A carry ROHS3 compliance certification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 rating, indicating unlimited shelf life under standard storage conditions without moisture bake-out requirements.
