QFSS-048-04.25-L-D-DP-A-P Equivalent & Substitute Parts

Part Overview

The QFSS-048-04.25-L-D-DP-A-P is a 96-position differential pair array connector manufactured by Samtec Inc. in the Q2™ QFSS series. This surface mount rectangular connector features a 0.025" (0.64mm) pitch, dual-row configuration with shielding and ground bus plane integration. The connector is designed for high-density interconnect applications requiring differential signaling with controlled impedance characteristics.

The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Identifying equivalent and substitute components is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QFSS-048-04.25-L-D-DP-A-P is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Differential Pair Array, Female orientation with 96 positions across 2 rows
• Pitch & Spacing: 0.025" (0.64mm) pitch maintaining identical contact spacing and alignment
• Mounting Technology: Surface mount configuration with identical board engagement and stacking height (11mm mated)
• Electrical & Mechanical Features: Board guide, ground bus plane, and shielding characteristics
• Contact Material & Finish: Gold plating at 10.0µin (0.25µm) thickness for consistent electrical performance
• Physical Dimensions: Height above board of 0.278" (7.06mm) for PCB clearance compatibility
• Compliance & Environmental: RoHS3 compliance and MSL 1 rating for manufacturing and storage conditions

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in any of these parameters disqualify a part from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

Both the QFSS-048-04.25-L-D-DP-A-P and QFSS-048-04.25-L-D-DP-A maintain Active product status within the Q2™ QFSS series, confirming ongoing manufacturer support and availability. Both parts carry full RoHS3 compliance certification, meeting current environmental and regulatory requirements for commercial and industrial applications.

The QFSS-048-04.25-L-D-DP-A substitute part demonstrates identical electrical, mechanical, and environmental specifications. Selection between these parts may be based on inventory availability, lead time requirements, or procurement source preferences, as both parts are functionally and mechanically interchangeable for applications requiring 96-position differential pair array connectors with the specified pitch, mounting configuration, and shielding characteristics.

Frequently Asked Questions (FAQ)

Q: What defines substitution eligibility for the QFSS-048-04.25-L-D-DP-A-P?

A: Substitution requires exact equivalence across connector type (Differential Pair Array, Female), position count (96), pitch (0.025"), row configuration (2), mounting method (Surface Mount), contact finish (Gold, 10.0µin), stacking height (11mm), and compliance certifications (RoHS3, MSL 1).

Q: Are the QFSS-048-04.25-L-D-DP-A-P and QFSS-048-04.25-L-D-DP-A mechanically compatible?

A: Yes. Both parts share identical mechanical dimensions, including height above board (0.278"), mated stacking height (11mm), board guide configuration, and shielding structure. PCB footprints and mounting requirements are identical.

Q: What is the difference between these two part numbers?

A: The QFSS-048-04.25-L-D-DP-A-P includes a "-P" suffix designation compared to QFSS-048-04.25-L-D-DP-A. All electrical, mechanical, and environmental parameters remain identical. The suffix may indicate packaging or distribution channel differentiation without affecting functional or physical compatibility.

Q: Can these connectors be used interchangeably in production?

A: Yes. Both parts meet identical specifications for differential pair array applications requiring 96-position, 0.025" pitch surface mount connectors with shielding and ground bus integration. Both maintain Active status and full RoHS3 compliance.

Q: What inventory status should be considered when selecting between these parts?

A: The QFSS-048-04.25-L-D-DP-A-P has 745 pieces in stock, while the QFSS-048-04.25-L-D-DP-A has 935 pieces available. Selection may prioritize the substitute part for immediate availability or the main part based on existing design documentation and procurement preferences.
