Engineering Selection Recommendations

Parametric Equivalent:

FCE17B25SC49B is a parametric equivalent to FCE17B25SC48B. Both parts are manufactured by Amphenol ICC, share identical electrical and mechanical specifications, and differ only in packaging format (Box versus standard packaging). Both maintain RoHS Compliance and active product status. This part is suitable for direct substitution in applications where packaging format does not impose constraints.

Similar Parts with Enhanced Specifications:

The TE Connectivity AMPLIMITE HD-20 series parts (5747838-3, 5747838-4, 5747838-6, 747838-3, 747838-4) provide higher current ratings (6A versus 5A) and extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C). These parts are suitable for applications requiring enhanced thermal performance or higher current capacity. Parts 5747838-4 and 747838-4 feature thicker gold contact finish (30.0µin versus 15.0µin or Flash), providing enhanced contact durability.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25SC49B be used as a direct replacement for FCE17B25SC48B?

A: Yes. FCE17B25SC49B is a parametric equivalent with identical electrical and mechanical specifications. The only difference is packaging format (Box). Both parts are manufactured by Amphenol ICC, maintain RoHS Compliance, and are actively produced.

Q: What are the key differences between FCE17B25SC48B and the TE Connectivity AMPLIMITE HD-20 series?

A: The primary differences are: (1) Current Rating: TE Connectivity parts are rated for 6A versus 5A for the Amphenol part; (2) Operating Temperature Range: TE Connectivity parts operate from -55°C ~ 105°C versus -40°C ~ 85°C for the Amphenol part; (3) Additional Features: TE Connectivity parts include Board Lock and Ground Strap; (4) Voltage Rating: TE Connectivity parts are rated for 125V, while the Amphenol part does not specify voltage rating; (5) Flange Feature: TE Connectivity parts feature Housing/Shell mounted flanges (except 5747838-6 which features Mating Side Female Screwlock), while the Amphenol part features Board Side mounting.

Q: Is the NorComp 183-025-213R571 compatible with FCE17B25SC48B?

A: The NorComp part is mechanically and electrically compatible for 25 position D-Sub receptacle applications. Key differences include: (1) Shell Material Finish: Nickel Plated versus Tin Plated; (2) Contact Material: Brass versus Phosphor Bronze; (3) Contact Finish Thickness: Flash versus 15.0µin; (4) Operating Temperature Range: -55°C ~ 105°C versus -40°C ~ 85°C; (5) Flange Feature: Housing/Shell mounted with Panel Mount capability versus Board Side mounting only; (6) Compliance: ROHS3 Compliant versus RoHS Compliant. Compatibility depends on application-specific requirements for shell material, contact material, and mounting configuration.

Q: Why do some substitute parts have higher current ratings?

A: The TE Connectivity AMPLIMITE HD-20 series parts are rated for 6A current capacity compared to 5A for the Amphenol FCE17B25SC48B. This reflects design differences in contact material (Phosphor Bronze), contact geometry, and thermal management. Higher current rating provides design margin for applications with elevated current requirements.

Q: What is the significance of contact finish thickness differences?

A: Contact finish thickness affects contact durability and wear resistance. The Amphenol FCE17B25SC48B features 15.0µin (0.38µm) gold plating. TE Connectivity parts 5747838-4 and 747838-4 feature 30.0µin (0.76µm) thickness, providing enhanced durability for high-cycle mating applications. Parts with Flash specification provide minimal gold plating suitable for standard applications. Thicker plating is beneficial for applications with frequent connector mating cycles.

Q: Are all substitute parts RoHS Compliant?

A: No. Part 747838-3 (TE Connectivity) is RoHS non-compliant. All other substitute parts listed are RoHS Compliant or ROHS3 Compliant. For applications requiring RoHS compliance, use FCE17B25SC49B, 183-025-213R571, 5747838-3, 5747838-4, 5747838-6, or 747838-4.

Q: What packaging formats are available for these D-Sub 25 position receptacles?

A: Packaging formats include: Box (FCE17B25SC49B), Tray (183-025-213R571), and Tube (5747838-3, 5747838-4, 5747838-6, 747838-3, 747838-4). Standard packaging for FCE17B25SC48B is not specified. Packaging selection depends on inventory management, handling, and assembly process requirements.

Q: Can parts with different flange features be interchanged?

A: Flange feature differences affect mounting configuration. FCE17B25SC48B features Board Side (4-40) mounting. NorComp 183-025-213R571 features Housing/Shell (4-40) mounting with Panel Mount capability. TE Connectivity parts feature Housing/Shell (4-40) mounting, except 5747838-6 which features Mating Side Female Screwlock (4-40). Interchangeability depends on PCB layout and mounting hole configuration. Board Side mounting requires mounting holes on the PCB board surface. Housing/Shell mounting uses the connector shell for mounting. Panel Mount capability allows mounting through panel cutouts.

Q: What is the significance of Board Lock and Ground Strap features?

A: Board Lock feature provides mechanical retention of the connector to the PCB, preventing accidental disconnection. Ground Strap provides electrical grounding path for EMI/RFI shielding. These features are present on TE Connectivity AMPLIMITE HD-20 series parts but not on the Amphenol FCE17B25SC48B. These features are beneficial for applications requiring enhanced mechanical security and electromagnetic shielding.
