QSE-020-01-F-D-A-GP Equivalent & Substitute Parts

Part Overview

The QSE-020-01-F-D-A-GP is a 40-position rectangular connector receptacle manufactured by Samtec Inc. as part of the Q Strip® QSE series. This surface mount connector features center strip contacts with gold plating and is designed for applications requiring reliable interconnection with mated stacking height flexibility. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from compatible alternatives within the same electrical and mechanical parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSE-020-01-F-D-A-GP is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Electrical specifications (40 positions, 0.031" pitch, 2 rows)
• Physical mounting characteristics (Surface Mount)
• Contact material and finish (Gold, 3.00µin thickness)
• Mechanical dimensions (Height Above Board: 0.128")
• Regulatory compliance (ROHS3, MSL 1)
• Series designation (Q Strip® QSE)

Parts meeting all these criteria are classified as parametric equivalents and may be substituted without modification to PCB layout, mating interface, or electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both QSE-020-01-F-D-A-GP and QSE-020-01-F-D-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and packaging considerations. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The substitute part QSE-020-01-F-D-A carries significantly higher inventory levels (92,600 pcs vs. 975 pcs), making it the preferred choice for applications where supply chain continuity is a priority.
