Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFS-026-04.25-L-D-A-GP is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Electrical specifications (52 positions, 0.025" pitch, 2 rows)
• Physical dimensions (Height above board: 0.278", Mated stacking heights: 10mm, 11mm, 14mm)
• Contact material and finish (Gold, 10.0µin thickness)
• Mounting technology (Surface Mount)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute differs only in packaging format, maintaining identical connector specifications and performance characteristics. This substitution model accommodates different supply chain and manufacturing assembly requirements without affecting electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the QFS-026-04.25-L-D-A-GP and QFS-026-04.25-L-D-A-GP-TR maintain Active product status with identical electrical and mechanical specifications. Selection between these parts is determined by assembly process requirements and packaging compatibility with automated placement equipment.

The Tray packaging (QFS-026-04.25-L-D-A-GP) is suitable for manual assembly operations and lower-volume production runs. The Tape & Reel packaging (QFS-026-04.25-L-D-A-GP-TR) is optimized for high-speed automated pick-and-place assembly systems.

Both parts satisfy ROHS3 compliance and MSL 1 moisture sensitivity requirements. No functional or performance differences exist between the two variants.
