Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSS5XSFAA48B are identified based on strict alignment with the following critical parameters:

Core Matching Criteria:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 50
• Number of Rows: 3
• Shell Size, Connector Layout: 5 (DD, D)
• Mounting Type: Through Hole
• Termination: Press-Fit
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• Color: Black
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in secondary parameters such as flange feature type, shell material finish, contact finish thickness, dielectric material composition, and operating temperature ranges are noted but do not preclude substitution when core parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—5747143-2, 5747144-2, and D50S91C6PA00LF—are functionally equivalent to the DSS5XSFAA48B based on alignment of core electrical and mechanical parameters. Selection among these alternatives is determined by application-specific requirements and compliance considerations:

5747143-2 (TE Connectivity AMPLIMITE HD-20 Series): This part is RoHS compliant with an operating temperature range of -55°C to 105°C. The flange feature is unthreaded housing/shell type. REACH status is vendor undefined. This part is suitable for applications requiring standard RoHS compliance within the specified temperature range.

5747144-2 (TE Connectivity AMPLIMITE HD-20 Series): This part is RoHS compliant with an operating temperature range of -55°C to 105°C. The flange feature includes 4-40 threaded mounting, matching the board-side flange configuration of the main part. REACH status is affected. This part provides the closest mechanical alignment to the DSS5XSFAA48B in terms of flange mounting configuration and is available in high inventory (35397 units).

D50S91C6PA00LF (Amphenol ICC Delta D Series): This part is RoHS compliant with an extended operating temperature range of -55°C to 125°C. The shell material finish is tin-nickel plated rather than tin plated. Contact material is phosphor bronze rather than copper alloy. REACH status is affected. This part is suitable for applications requiring extended temperature performance and is packaged in trays.

All substitute parts maintain UL94 V-0 flammability rating, MSL 1 (unlimited) moisture sensitivity, and gold contact finish. Selection should be based on flange mounting requirements, temperature operating range, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 5747143-2 be used as a direct replacement for DSS5XSFAA48B?

A: Yes. Both parts share identical core parameters: 50 position D-Sub receptacle, female sockets, 3-row configuration, shell size 5 (DD, D), through-hole mounting, press-fit termination, gold contact finish, and UL94 V-0 flammability rating. The primary difference is the flange feature type (unthreaded housing/shell versus board-side 4-40). Mechanical fit must be verified for the specific application.

Q: What is the difference between 5747144-2 and 5747143-2?

A: Both are TE Connectivity AMPLIMITE HD-20 series parts with identical electrical specifications. The key difference is the flange feature: 5747144-2 includes 4-40 threaded mounting on the housing/shell, while 5747143-2 has unthreaded housing/shell. The 5747144-2 flange configuration more closely matches the DSS5XSFAA48B board-side 4-40 mounting. Additionally, 5747144-2 has significantly higher inventory availability (35397 units versus 846 units).

Q: Is D50S91C6PA00LF compatible with the same mating connector as DSS5XSFAA48B?

A: Yes. Both are 50 position D-Sub receptacles with identical shell size (5, DD, D) and row configuration (3 rows). The connector will mate with standard 50 position D-Sub plugs. However, the shell material finish differs (tin-nickel plated versus tin plated), and the contact material is phosphor bronze rather than copper alloy. These material differences do not affect mating compatibility but may influence electrical performance characteristics in specific applications.

Q: What is the operating temperature difference between these parts?

A: The DSS5XSFAA48B does not specify an operating temperature range. The TE Connectivity parts (5747143-2 and 5747144-2) operate from -55°C to 105°C. The Amphenol ICC part (D50S91C6PA00LF) operates from -55°C to 125°C, providing a 20°C extended upper temperature limit. Selection should be based on the application's thermal requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are RoHS compliant. However, REACH status differs: DSS5XSFAA48B is REACH unaffected, 5747143-2 is vendor undefined, and both 5747144-2 and D50S91C6PA00LF are REACH affected. Applications subject to REACH regulations should verify compliance requirements with the specific part manufacturer.

Q: What packaging formats are available?

A: DSS5XSFAA48B is supplied in standard packaging (not specified). 5747143-2 and 5747144-2 are supplied in bulk packaging. D50S91C6PA00LF is supplied in tray packaging. Packaging format may affect handling, storage, and integration into assembly processes.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical and mechanical interchangeability is confirmed for all core parameters. However, physical fit must be verified due to flange feature variations. The DSS5XSFAA48B uses board-side 4-40 mounting; 5747144-2 matches this configuration, while 5747143-2 and D50S91C6PA00LF use unthreaded housing/shell flanges. PCB mounting hole patterns and mechanical clearances must be evaluated for each application.
