Substitute Part Grouping Explanation

Substitution eligibility for the QTE-020-04-L-D-A-TR is determined by strict equivalence across the following critical parameters:

• Number of Positions: 40
• Pitch: 0.031" (0.80mm)
• Number of Rows: 2
• Connector Type: Header, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 10.0µin (0.25µm)
• Height Above Board: 0.600" (15.24mm)
• Mated Stacking Heights: 16mm
• Features: Board Guide, Ground Bus (Plane)
• Series: Q Strip® QTE
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

The identified substitute part differs only in packaging format (Tape & Reel versus Tray), which does not affect electrical or mechanical performance. Both parts are manufactured by Samtec Inc. and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both QTE-020-04-L-D-A-TR and QTE-020-04-L-D-A are Active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts is determined by packaging requirements and supply chain considerations rather than functional performance.

The QTE-020-04-L-D-A-TR (Tape & Reel packaging) is suitable for high-volume automated assembly operations where tape-fed component handling is standard. The QTE-020-04-L-D-A (Tray packaging) accommodates manual assembly processes or applications where tray-based component management is preferred. Both parts deliver identical electrical and mechanical performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can QTE-020-04-L-D-A be used as a direct replacement for QTE-020-04-L-D-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. QTE-020-04-L-D-A uses Tray packaging while QTE-020-04-L-D-A-TR uses Tape & Reel packaging. Substitution is valid provided assembly equipment and handling procedures accommodate the different packaging format.

Q: What determines substitution eligibility for this connector?

A: Substitution is valid when the following parameters remain identical: number of positions (40), pitch (0.031"/0.80mm), number of rows (2), connector type (Header, Outer Shroud Contacts), mounting type (Surface Mount), contact finish (Gold at 10.0µin thickness), height above board (0.600"/15.24mm), mated stacking height (16mm), and features (Board Guide, Ground Bus Plane).

Q: Are there compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and MSL rating of 1 (Unlimited). Both are Active products from Samtec Inc.

Q: Which packaging format should I select?

A: Selection depends on assembly process requirements. Tape & Reel (TR) packaging is standard for automated pick-and-place assembly. Tray packaging is used for manual assembly or when tape-fed component handling is not available.
