QFS-032-04.25-L-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QFS-032-04.25-L-D-DP-A-TR is a 64-position differential pair array connector from Samtec Inc.'s Power Q2™ QFS series. This surface mount female connector features gold-plated contacts and is designed for high-density interconnect applications requiring differential signaling. The part is currently active in production and ROHS3 compliant. Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFS-032-04.25-L-D-DP-A-TR is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Differential Pair Array, Female)
• Position count (64 positions)
• Pitch specification (0.025" / 0.64mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold, 10.0µin thickness)
• Mechanical envelope (Height above board, mated stacking heights)
• Compliance certifications (ROHS3, MSL 1)

The primary variable among qualified substitutes is packaging format. The QFS-032-04.25-L-D-DP-A-TR is supplied in Tape & Reel (TR) packaging, while equivalent alternatives may be available in alternative packaging configurations such as Tray. All other electrical, mechanical, and environmental specifications remain identical across the substitute group.

Parameter Comparison

Engineering Selection Recommendations

Both the QFS-032-04.25-L-D-DP-A-TR and QFS-032-04.25-L-D-DP-A are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain considerations:

• QFS-032-04.25-L-D-DP-A-TR (Tape & Reel): Suitable for automated assembly processes requiring continuous reel feeding.
• QFS-032-04.25-L-D-DP-A (Tray): Suitable for manual assembly, lower-volume production, or applications where reel packaging is not required.

Both parts meet ROHS3 compliance and carry MSL 1 rating, indicating no moisture sensitivity restrictions. Export classification (EAR99) and tariff codes (HTSUS 8536.69.4040) are identical, presenting no regulatory differentiation.

Frequently Asked Questions (FAQ)

Q: Can QFS-032-04.25-L-D-DP-A (Tray) be used as a direct replacement for QFS-032-04.25-L-D-DP-A-TR (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Tray packaging is compatible with manual pick-and-place or alternative assembly methods. Tape & Reel packaging is optimized for automated high-speed assembly equipment.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, MSL 1 rating, EAR99 export classification, and HTSUS tariff codes.

Q: What is the significance of the 0.025" (0.64mm) pitch specification?

A: Pitch defines the center-to-center spacing between adjacent contact positions. This 0.025" pitch is a critical mechanical parameter that determines PCB footprint compatibility. Substitutes must maintain this exact pitch specification.

Q: Do the mated stacking heights affect substitution eligibility?

A: Yes. The available mated stacking heights (10mm, 11mm, 14mm) define the connector's vertical engagement range. Substitutes must support the same stacking height options to ensure proper mating with corresponding plug connectors.

Q: Is the gold contact finish thickness critical for substitution?

A: Yes. The 10.0µin (0.25µm) contact finish thickness is a specified parameter that affects contact durability and electrical performance. Substitutes must maintain this exact thickness specification.
