Key Parameters

Substitute Part Grouping Explanation

Substitution of the 747021-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 15
• Number of Rows: 2
• Shell Size, Connector Layout: 2 (DA, A)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Current Rating: 6A
• Voltage Rating: 125V
• Operating Temperature Range: -55°C ~ 105°C
• Flange Feature: Mating Side, Female Screwlock (4-40)
• Features: Mounting Brackets

The substitute part 5747021-2 meets all mandatory matching parameters and is therefore classified as a direct equivalent. The primary distinction between the main part and substitute is product status (obsolete versus active) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 5747021-2 is a direct functional equivalent to the 747021-2 across all electrical and mechanical parameters. The substitute part is classified as active product status, ensuring ongoing availability and supply chain continuity.

Compliance Considerations:

The 747021-2 is RoHS non-compliant, while the 5747021-2 is RoHS Compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 5747021-2 is the appropriate selection.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, indicating equivalent export control and tariff treatment.

Dielectric Material Difference:

The main part specifies thermoplastic dielectric material, while the substitute specifies polyamide (PA) nylon with glass filling. Both materials support the identical operating temperature range (-55°C ~ 105°C) and voltage rating (125V).

Contact Finish Thickness:

The main part specifies 30.0µin (0.76µm) gold contact finish thickness, while the substitute specifies flash gold plating. Both finishes provide equivalent electrical performance and corrosion resistance for the 6A, 125V application.

Frequently Asked Questions (FAQ)

Q: Can the 5747021-2 be used as a direct replacement for the 747021-2 in existing designs?

A: Yes. The 5747021-2 meets all electrical and mechanical specifications of the 747021-2, including connector style, position count, shell size, mounting type, current rating, voltage rating, and operating temperature range. The parts are functionally interchangeable.

Q: What is the significance of the product status difference (obsolete versus active)?

A: The 747021-2 is classified as obsolete, indicating TE Connectivity no longer manufactures or supports this part number. The 5747021-2 is active product, ensuring continued availability, technical support, and supply chain reliability for new procurements and ongoing applications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance is a regulatory and material composition requirement, not an electrical performance specification. Both parts deliver identical electrical characteristics. RoHS compliance becomes a selection criterion only when mandated by customer specifications, regional regulations, or design standards.

Q: Are the dielectric material differences significant?

A: Both dielectric materials (thermoplastic and polyamide nylon glass-filled) support the identical operating temperature range and voltage rating. The material difference does not affect electrical performance or mechanical compatibility in this application.

Q: What does the contact finish thickness difference mean?

A: The main part specifies 30.0µin (0.76µm) gold plating, while the substitute specifies flash gold plating (typically 5-10µin). Both finishes provide adequate corrosion resistance and electrical conductivity for the 6A, 125V signal application. Flash plating is a cost-effective alternative that meets performance requirements.

Q: Are there any compatibility issues with existing mating connectors?

A: No. Both the 747021-2 and 5747021-2 are 15-position D-Sub receptacles with identical shell size (2/DA, A), pin configuration, and mating interface. They are compatible with standard D-Sub plugs and cable assemblies designed for 15-position D-Sub receptacles.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts feature identical through-hole right-angle solder termination, mounting bracket configuration, and footprint requirements. They can be used interchangeably in PCB designs without layout or assembly modifications.
