Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the QSE-028-01-F-D-DP-A-TR are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain identical connector type (Differential Pair Array, Female), position count (56), pitch (0.031"), row configuration (2), and contact finish (Gold).

Mechanical Compatibility: All parts share the same mounting type (Surface Mount), height above board (0.128"), and feature set (Board Guide, Ground Bus).

Environmental Compliance: All parts maintain MSL 1 (Unlimited) rating and are RoHS compliant.

Allowable Variations: Packaging format (Tape & Reel vs. Tray) and manufacturer source are permitted substitution variables. Contact finish thickness may vary (3.00µin vs. Flash). Mated stacking height options may differ within the range provided.

Parameter Comparison

Engineering Selection Recommendations

QSE-028-01-F-D-DP-A (Samtec, Tray Packaging): This part is functionally identical to the main part number with the exception of packaging format. Both are manufactured by Samtec Inc., maintain identical electrical and mechanical specifications, and carry ROHS3 compliance. Selection is appropriate when Tray packaging meets assembly requirements and inventory availability is prioritized.

5-1658043-2 (TE Connectivity, Tape & Reel Packaging): This part maintains all critical electrical and mechanical parameters including connector type, position count, pitch, mounting configuration, and height. Both parts are Active status and RoHS compliant. The contact finish thickness differs (Flash vs. 3.00µin), and mated stacking height options include additional configurations (22mm, 30mm). Selection is appropriate when cross-manufacturer sourcing is acceptable and Tape & Reel packaging is required.

Frequently Asked Questions (FAQ)

Q: Can QSE-028-01-F-D-DP-A (Tray) be used as a direct substitute for QSE-028-01-F-D-DP-A-TR (Tape & Reel)?

A: Yes. Both parts are identical in electrical and mechanical specifications. The difference is packaging format only. Tray packaging is suitable for applications where automated tape feeding is not required or where bulk component handling is preferred.

Q: What is the difference between the Samtec QSE series and the TE Connectivity MICTOR SB series in this application?

A: Both connectors meet the electrical and mechanical requirements for 56-position differential pair array applications at 0.031" pitch. The primary differences are manufacturer source and contact finish thickness specification. The TE Connectivity part offers additional mated stacking height options (22mm and 30mm).

Q: Are there any compliance differences between these parts?

A: All three parts are RoHS compliant and carry MSL 1 (Unlimited) rating. The main part and Samtec substitute are ROHS3 compliant, while the TE Connectivity part is RoHS compliant. All parts carry EAR99 ECCN classification.

Q: Does contact finish thickness affect interchangeability?

A: Contact finish thickness does not affect mechanical or electrical interchangeability in this application. The 3.00µin specification on Samtec parts and Flash specification on the TE Connectivity part both provide adequate gold plating for connector performance and durability.

Q: Can the TE Connectivity 5-1658043-2 be used in applications designed for the Samtec QSE series?

A: Yes. The TE Connectivity part maintains all critical parameters required for differential pair array connector applications. Cross-manufacturer substitution is valid when electrical and mechanical specifications align, as they do in this case.
