QSS-025-01-H-D-A-TR Equivalent & Substitute Parts

Part Overview

The QSS-025-01-H-D-A-TR is a 50-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 applications requiring high-density interconnection with 0.025" pitch spacing. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to packaging availability, inventory constraints, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSS-025-01-H-D-A-TR is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Socket configuration with 50 positions
• Pitch & Row Configuration: 0.025" (0.64mm) pitch with 2-row arrangement
• Contact System: Center strip contacts with gold finish at 30.0µin thickness
• Mounting Technology: Surface mount design
• Physical Dimensions: Height above board of 0.143" (3.63mm) and 5mm mated stacking height
• Electrical & Environmental Compliance: ROHS3 compliance and MSL 1 rating

The identified substitute part differs only in packaging format (Tray versus Tape & Reel), which does not affect electrical or mechanical compatibility. All other specifications remain identical, making this substitution valid for applications where packaging flexibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the QSS-025-01-H-D-A-TR and QSS-025-01-H-D-A are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

• QSS-025-01-H-D-A-TR (Tape & Reel): Suitable for high-volume automated assembly processes where tape and reel packaging provides efficient component feeding and handling.

• QSS-025-01-H-D-A (Tray): Suitable for lower-volume applications, manual assembly, or situations where tray packaging is preferred for component organization and storage.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and long-term storage without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can QSS-025-01-H-D-A be used as a direct replacement for QSS-025-01-H-D-A-TR?

A: Yes. The parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). Substitution is valid provided your assembly process can accommodate the alternative packaging.

Q: Does packaging format affect PCB assembly compatibility?

A: No. Packaging format does not affect the connector's electrical performance, mechanical fit, or board-level compatibility. The component itself remains unchanged regardless of whether it arrives in tape and reel or tray packaging.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance certification and MSL 1 rating. Environmental and regulatory compliance is equivalent.

Q: What determines if a part can substitute for the QSS-025-01-H-D-A-TR?

A: Substitution requires matching specifications across connector type, position count, pitch, row configuration, contact finish, mounting type, height dimensions, and compliance certifications. Packaging format is the only parameter that may differ without affecting substitution validity.

Q: Is inventory status a factor in substitution eligibility?

A: No. Inventory levels do not determine technical substitution eligibility. Parts are substitutes based on electrical and mechanical equivalence. Inventory availability may influence procurement decisions but does not affect engineering compatibility.
