Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFS-052-04.25-L-D-A-TR is determined by strict equivalence across the following critical parameters:

• Number of positions: 104
• Pitch: 0.025" (0.64mm)
• Number of rows: 2
• Connector type: Receptacle, Center Strip Contacts
• Mounting type: Surface Mount
• Contact finish: Gold with 10.0µin thickness
• Height above board: 0.278" (7.06mm)
• Mated stacking heights: 10mm, 11mm, 14mm
• Features: Board Guide, Ground Bus (Plane)
• Series: Power Q2™ QFS
• RoHS and MSL compliance levels

The identified substitute part differs only in packaging format (Tray versus Tape & Reel), which does not affect electrical or mechanical performance. All other specifications remain identical, making this substitution valid for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the QFS-052-04.25-L-D-A-TR and QFS-052-04.25-L-D-A are active production components with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

The QFS-052-04.25-L-D-A-TR is supplied in Tape & Reel format, suitable for automated assembly processes requiring continuous component feeding. The QFS-052-04.25-L-D-A is supplied in Tray packaging, offering higher current inventory levels (4428 units versus 990 units) and flexibility for manual or semi-automated assembly operations.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. No additional testing or qualification is required when substituting between these packaging formats, as all functional and environmental specifications remain constant.

Frequently Asked Questions (FAQ)
