QTE-020-01-L-D-A-SD Equivalent & Substitute Parts

Part Overview

The QTE-020-01-L-D-A-SD is a 40-position rectangular connector header manufactured by Samtec Inc. as part of the Q Strip® QTE series. This surface mount component features outer shroud contacts with gold plating and is designed for applications requiring dual-row connectivity with board guide and ground bus plane features. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the QTE-020-01-L-D-A-SD is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Header, Outer Shroud Contacts)
• Position count and row configuration (40 positions, 2 rows)
• Pitch specification (0.031" / 0.80mm)
• Surface mount mounting type
• Contact finish material and thickness (Gold, 10.0µin)
• Physical dimensions (Height Above Board: 0.168", Mated Stacking Height: 5mm)
• Integrated features (Board Guide, Ground Bus Plane)
• Compliance certifications (ROHS3, MSL 1)

The QTE-020-01-L-D-A variant qualifies as a parametric equivalent substitute based on identical alignment across all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the QTE-020-01-L-D-A-SD and QTE-020-01-L-D-A maintain Active product status within the Samtec Q Strip® QTE series. Both components satisfy ROHS3 compliance requirements and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling. The QTE-020-01-L-D-A offers significantly higher inventory availability (92,900 pcs vs. 782 pcs), making it the preferred selection for applications where lead time and supply chain continuity are critical factors. Component selection between these equivalents should be based on procurement timeline, inventory requirements, and supply chain strategy rather than electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Are QTE-020-01-L-D-A-SD and QTE-020-01-L-D-A electrically interchangeable?

A: Yes. Both components share identical electrical specifications including 40-position configuration, 0.031" pitch, gold contact finish at 10.0µin thickness, and ground bus plane integration. No circuit redesign or layout modification is required for substitution.

Q: What is the difference between these two part numbers?

A: The QTE-020-01-L-D-A-SD and QTE-020-01-L-D-A are parametrically equivalent. The suffix designation (-SD) on the main part number does not reflect differences in electrical or mechanical performance. The primary distinction is inventory availability and procurement source.

Q: Can I use QTE-020-01-L-D-A as a direct replacement in existing designs?

A: Yes. The QTE-020-01-L-D-A is a direct substitute. All physical dimensions, mounting characteristics, contact specifications, and compliance certifications are identical. No PCB layout or assembly process modifications are necessary.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QTE-020-01-L-D-A-SD and QTE-020-01-L-D-A meet ROHS3 compliance requirements and carry MSL 1 moisture sensitivity rating.

Q: What is the board-to-board mating height for these connectors?

A: The mated stacking height is 5mm for both components. The height above board is 0.168" (4.27mm), which defines the clearance requirement for mating connector placement.
