Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the QFS-026-04.25-L-D-A-P are identified based on equivalence in the following critical parameters:

• Number of Positions: 52
• Pitch: 0.025" (0.64mm)
• Number of Rows: 2
• Connector Type: Receptacle, Center Strip Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Contact Finish Thickness: 10.0µin (0.25µm)
• Height Above Board: 0.278" (7.06mm)
• Mated Stacking Heights: 10mm, 11mm, 14mm
• Series: Power Q2™ QFS
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The primary differentiator between the main part and its substitute is packaging configuration. The QFS-026-04.25-L-D-A-P is supplied in Tray packaging, while the substitute variant utilizes Tape & Reel (TR) packaging. Both parts are electrically and mechanically identical, with substitution appropriate when packaging requirements align with assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the QFS-026-04.25-L-D-A-P and QFS-026-04.25-L-D-A-P-TR are Active products with ROHS3 compliance and MSL 1 rating, indicating unlimited shelf life under standard storage conditions. Selection between these parts is determined by assembly process requirements and supply chain logistics rather than electrical or mechanical performance.

The Tray packaging variant (QFS-026-04.25-L-D-A-P) is suitable for manual assembly and lower-volume production runs. The Tape & Reel variant (QFS-026-04.25-L-D-A-P-TR) is optimized for automated pick-and-place assembly processes and high-volume manufacturing environments. Both configurations support the Pick and Place feature set, enabling compatibility with standard surface mount assembly equipment when appropriate packaging is selected.

Frequently Asked Questions (FAQ)

Q: Are the QFS-026-04.25-L-D-A-P and QFS-026-04.25-L-D-A-P-TR electrically identical?

A: Yes. Both parts are identical in electrical performance, contact configuration, pitch, number of positions, and all functional parameters. The only difference is packaging format.

Q: What is the primary difference between Tray and Tape & Reel packaging?

A: Tray packaging is used for manual handling and lower-volume applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment and high-volume production. The connector itself is functionally equivalent.

Q: Can I substitute the Tape & Reel variant for the Tray variant in my assembly process?

A: Substitution is possible only if your assembly equipment supports Tape & Reel feeding. Conversely, Tray packaging cannot be used in automated tape-fed systems. Verify your assembly process compatibility before substitution.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QFS-026-04.25-L-D-A-P and QFS-026-04.25-L-D-A-P-TR are ROHS3 compliant.

Q: What is the Moisture Sensitivity Level for these connectors?

A: Both parts have MSL 1 rating, indicating unlimited shelf life under standard storage conditions with no special moisture control requirements.

Q: Do both packaging variants support automated assembly?

A: The Tape & Reel variant (QFS-026-04.25-L-D-A-P-TR) is specifically designed for automated pick-and-place assembly. The Tray variant (QFS-026-04.25-L-D-A-P) supports manual assembly and can be used with automated equipment if manual feeding is configured.
