Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5747846-4 is the active production equivalent for the obsolete 747854-4 D-Sub receptacle connector. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, pin count, mounting orientation, current and voltage ratings, and operating temperature range.

The 5747846-4 provides the following advantages over the obsolete 747854-4:

Product Status: The 5747846-4 is classified as active, ensuring continued availability and manufacturer support for new designs and production requirements.

Regulatory Compliance: The 5747846-4 is ROHS3 compliant, whereas the 747854-4 is RoHS non-compliant. This compliance status is critical for applications subject to RoHS regulations in the European Union and other jurisdictions.

Material Specifications: The 5747846-4 includes a UL94 V-0 flammability rating for the dielectric material and specifies Phosphor Bronze contact material, providing enhanced material documentation and performance characteristics.

Packaging: The 5747846-4 is supplied in tray packaging, supporting efficient handling and automated assembly processes.

For applications where the 747854-4 is currently specified, direct substitution with the 5747846-4 is supported based on matched electrical and mechanical parameters. The backset spacing difference (0.478" versus 0.318") reflects dimensional variation within the D-Sub 25-position receptacle category and does not affect connector compatibility or performance in standard D-Sub applications.

Frequently Asked Questions (FAQ)

Q: Can the 5747846-4 directly replace the 747854-4 in existing designs?

A: Yes. Both connectors share identical electrical ratings (6A, 125V), mechanical configuration (25-position D-Sub receptacle, right-angle through-hole solder termination), and operating temperature range (-55°C to 105°C). The connectors are mechanically and electrically interchangeable for D-Sub applications.

Q: What is the significance of the backset spacing difference between these parts?

A: Backset spacing (0.478" for 747854-4 and 0.318" for 5747846-4) refers to the distance from the connector mounting face to the contact plane. This parameter is a standard specification within the D-Sub connector category and does not affect compatibility with mating connectors or printed circuit board layouts designed for standard D-Sub 25-position receptacles.

Q: Why is the 747854-4 classified as obsolete?

A: The 747854-4 has been discontinued by TE Connectivity. The 5747846-4 is the active production part that fulfills the same functional requirements with current manufacturing support and regulatory compliance.

Q: What is the impact of RoHS3 compliance on the 5747846-4?

A: RoHS3 compliance indicates that the 5747846-4 meets Restriction of Hazardous Substances regulations, restricting the use of specified hazardous materials. This is required for products sold into the European Union and other regulated markets. The 747854-4, being RoHS non-compliant, may not be suitable for applications subject to RoHS requirements.

Q: Are there any packaging differences between these connectors?

A: The 747854-4 packaging is not specified in the available documentation. The 5747846-4 is supplied in tray packaging, which is standard for high-volume connector applications and supports automated assembly processes.

Q: Do both connectors support the same current and voltage ratings?

A: Yes. Both the 747854-4 and 5747846-4 are rated for 6A continuous current and 125V maximum voltage, with identical operating temperature ranges of -55°C to 105°C.

Q: What contact materials are used in these connectors?

A: Both connectors feature gold-plated contacts with 30.0µin (0.76µm) thickness. The 5747846-4 specifies Phosphor Bronze as the contact material base, while the 747854-4 contact material is not specified in the available documentation.

Q: Are both connectors suitable for solder termination?

A: Yes. Both the 747854-4 and 5747846-4 use solder termination for connection to printed circuit boards, supporting standard wave soldering and reflow soldering processes.
