Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QTE-028-01-L-D-DP-A-TR is determined by strict equivalence across the following critical parameters:

• Connector type and differential pair array configuration
• Position count (56 positions)
• Pitch specification (0.031" / 0.80mm)
• Row configuration (2 rows)
• Contact finish material and thickness (Gold, 10.0µin)
• Mechanical dimensions (mated stacking height, height above board)
• Mounting technology (surface mount)
• Electrical features (board guide, ground bus plane)
• Compliance certifications (ROHS3, MSL Level 1)

The primary variable distinguishing substitute parts is packaging format. The QTE-028-01-L-D-DP-A-TR is supplied in Tape & Reel (TR) packaging, while equivalent parts may be available in alternative packaging configurations such as Tray. All other electrical, mechanical, and compliance parameters remain identical across the substitute group.

Parameter Comparison

Engineering Selection Recommendations

Both the QTE-028-01-L-D-DP-A-TR and QTE-028-01-L-D-DP-A are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

The QTE-028-01-L-D-DP-A-TR in Tape & Reel packaging is optimized for automated assembly processes and high-volume production environments. The QTE-028-01-L-D-DP-A in Tray packaging provides flexibility for lower-volume applications or manual assembly workflows.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming suitability for standard manufacturing and storage conditions without moisture sensitivity constraints. Component selection should be based on assembly equipment compatibility and procurement volume requirements.

Frequently Asked Questions (FAQ)

Q: Can QTE-028-01-L-D-DP-A be used as a direct replacement for QTE-028-01-L-D-DP-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. QTE-028-01-L-D-DP-A (Tray) can substitute for QTE-028-01-L-D-DP-A-TR (Tape & Reel) provided the assembly process accommodates tray-packaged components.

Q: What is the primary difference between these substitute parts?

A: Packaging configuration. QTE-028-01-L-D-DP-A-TR uses Tape & Reel packaging for automated pick-and-place assembly. QTE-028-01-L-D-DP-A uses Tray packaging for manual or alternative assembly methods. All connector specifications remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance and MSL Level 1 ratings. No additional testing or qualification is required when switching between these parts.

Q: Does packaging affect the connector's electrical performance?

A: No. Packaging is a supply and assembly consideration only. The connector's electrical characteristics, impedance, contact resistance, and differential pair performance are identical regardless of packaging format.

Q: Which packaging should I select for my application?

A: Selection depends on your assembly process. Tape & Reel (TR) is standard for automated assembly lines. Tray packaging is suitable for manual assembly, lower-volume production, or when automated equipment is not available.
