Substitute Part Grouping Explanation

Substitution eligibility for the QSE-020-01-F-D-A-K is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and its substitute is packaging format.

The substitute part QSE-020-01-F-D-A-K-TR maintains identical specifications across the following critical parameters:

• Number of positions (40)
• Pitch (0.031" / 0.80mm)
• Number of rows (2)
• Connector type (Receptacle, Center Strip Contacts)
• Mounting type (Surface Mount)
• Contact finish and thickness (Gold, 3.00µin)
• Height above board (0.128" / 3.25mm)
• Mated stacking heights (5mm through 25mm)
• Compliance certifications (ROHS3, REACH Unaffected)
• Base product number (QSE-020)

The only variation is packaging: the main part is supplied in Tray format, while the substitute is supplied in Tape & Reel (TR) format. Both parts are manufactured by Samtec Inc. and carry active product status.

Parameter Comparison

Engineering Selection Recommendations

Both QSE-020-01-F-D-A-K and QSE-020-01-F-D-A-K-TR are active products manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on assembly process requirements and packaging compatibility.

The Tray packaging format (QSE-020-01-F-D-A-K) is suitable for manual assembly and lower-volume production runs. The Tape & Reel format (QSE-020-01-F-D-A-K-TR) is optimized for automated pick-and-place assembly processes and high-volume manufacturing.

Both parts meet ROHS3 compliance requirements and carry REACH Unaffected status. Moisture sensitivity level 1 indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can QSE-020-01-F-D-A-K-TR be used as a direct replacement for QSE-020-01-F-D-A-K?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Substitution is valid provided your assembly process can accommodate Tape & Reel packaging.

Q: What is the difference between Tray and Tape & Reel packaging?

A: Tray packaging is manual-friendly and suitable for hand assembly or low-volume pick operations. Tape & Reel packaging is designed for automated pick-and-place equipment and high-volume production lines. The connector itself is identical in both formats.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance and REACH Unaffected status. Moisture sensitivity level is 1 (Unlimited) for both variants.

Q: What are the mated stacking height options?

A: Both parts support mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm. Selection depends on your application's vertical space requirements.

Q: Is the contact finish identical between both parts?

A: Yes. Both parts feature gold-plated contacts with 3.00µin (0.076µm) thickness, ensuring equivalent electrical performance and reliability.
