Key Parameters

Substitute Part Grouping Explanation

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

• Connector type and position count (56-position differential pair array, male)
• Electrical specifications (pitch, contact finish, contact finish thickness)
• Mechanical dimensions (mated stacking height, height above board, number of rows)
• Mounting technology (surface mount)
• Compliance certifications (RoHS3, MSL rating)
• Series designation (Q Strip® QTE)

The primary variable among equivalent parts is packaging format. The QTE-028-01-F-D-DP-A-TR is supplied in tape and reel (TR) packaging, while substitute parts may be available in alternative packaging configurations such as tray. All other electrical, mechanical, and compliance parameters remain identical across the substitution group.

Parameter Comparison

Engineering Selection Recommendations

Both the QTE-028-01-F-D-DP-A-TR and QTE-028-01-F-D-DP-A are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on packaging requirements and inventory availability rather than functional differences.

The QTE-028-01-F-D-DP-A-TR in tape and reel packaging is suitable for high-volume automated assembly operations. The QTE-028-01-F-D-DP-A in tray packaging accommodates manual assembly processes or lower-volume production runs. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard surface mount assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Are QTE-028-01-F-D-DP-A-TR and QTE-028-01-F-D-DP-A electrically identical?

A: Yes. Both parts are 56-position differential pair array connectors with identical pitch (0.031"), contact finish (gold, 3.00µin thickness), and electrical characteristics. They differ only in packaging format.

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

A: The QTE-028-01-F-D-DP-A-TR is supplied in tape and reel packaging for automated pick-and-place assembly. The QTE-028-01-F-D-DP-A is supplied in tray packaging for manual handling or lower-volume applications. All other specifications are identical.

Q: Can I use QTE-028-01-F-D-DP-A in place of QTE-028-01-F-D-DP-A-TR on the same PCB?

A: Yes. The connectors are mechanically and electrically equivalent. Packaging format does not affect board-level compatibility or performance.

Q: Are both parts RoHS compliant?

A: Yes. Both QTE-028-01-F-D-DP-A-TR and QTE-028-01-F-D-DP-A are ROHS3 compliant with MSL 1 rating.

Q: What are the mated stacking height specifications?

A: Both parts have a mated stacking height of 5mm and a height above board of 0.168" (4.27mm).
