Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSH-090-01-L-D-A-TR is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Number of positions (180), pitch (0.020"/0.50mm), number of rows (2), connector type (receptacle with center strip contacts), and contact finish (gold at 10.0µin thickness)
• Mechanical Compatibility: Mounting type (surface mount), height above board (0.128"/3.25mm), mated stacking heights (5mm through 25mm), and features (board guide and ground bus plane)
• Compliance & Environmental: RoHS3 compliance, MSL rating (1 - unlimited), and active product status
• Packaging Variation: The primary substitute differs only in packaging format (tray versus tape & reel), which does not affect electrical or mechanical function

The identified substitute maintains complete functional equivalence and is suitable for direct replacement in applications where the QSH-090-01-L-D-A-TR is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the QSH-090-01-L-D-A-TR and QSH-090-01-L-D-A are active products from Samtec Inc. with identical electrical and mechanical specifications. The parts are fully equivalent for circuit design and PCB assembly applications. Selection between these parts should be based on packaging requirements and procurement logistics:

• QSH-090-01-L-D-A-TR (Tape & Reel): Suitable for high-volume automated assembly operations where tape and reel packaging is standard for pick-and-place equipment.
• QSH-090-01-L-D-A (Tray): Suitable for lower-volume applications, manual assembly, or where tray packaging is preferred for handling and storage.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can QSH-090-01-L-D-A be used as a direct replacement for QSH-090-01-L-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tray versus tape & reel). Direct substitution is valid for circuit function and PCB assembly.

Q: Does packaging format affect connector performance?

A: No. Packaging format (tape & reel or tray) is a logistics and handling consideration only. It does not affect electrical performance, mechanical fit, or reliability of the connector itself.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status, MSL rating (1 - unlimited), and active product status. They meet the same environmental and regulatory standards.

Q: What determines if a part can substitute for the QSH-090-01-L-D-A-TR?

A: Substitution requires matching specifications across: number of positions (180), pitch (0.020"/0.50mm), number of rows (2), connector type (receptacle with center strip contacts), contact finish (gold at 10.0µin), mounting type (surface mount), height above board (0.128"/3.25mm), mated stacking heights (5mm-25mm), and features (board guide and ground bus plane).

Q: Which packaging option should I select for my application?

A: Select tape & reel (QSH-090-01-L-D-A-TR) for automated high-volume assembly. Select tray (QSH-090-01-L-D-A) for manual assembly, prototyping, or lower-volume production where tray handling is preferred.
