TE Connectivity 206478-4 D-Sub Backshell Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 206478-4 is a 37-position hinged backshell connector from the AMPLIMITE HD-20 series, designed for D-Sub applications with 45° and 180° cable exit angles. This component functions as an accessory backshell assembly for 37-position and HD62-position D-Sub connectors, featuring unshielded construction with thermoplastic housing and integrated strain relief hardware.

The 206478-4 carries an obsolete product status, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Substitution is necessary to ensure access to components with current manufacturing support, compliance certifications, and inventory availability.

• Cable Interface: Round cable type with 45° and 180° exit angle capability
• Electrical Properties: Unshielded construction
• Material Composition: Thermoplastic housing with black color
• Hardware Specification: 4-40 mating screws with integrated strain relief

The substitute part 5206478-4 satisfies all these parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 5206478-4 is the direct equivalent substitute for the obsolete 206478-4. Selection of the substitute part is supported by the following factors:

Product Status: The 206478-4 is classified as obsolete, whereas the 5206478-4 maintains active product status with ongoing manufacturer support and availability.

Regulatory Compliance: The 5206478-4 is RoHS compliant and carries REACH Unaffected status, compared to the non-compliant and vendor-undefined status of the original part. This compliance improvement is significant for applications subject to environmental and regulatory requirements.

Inventory Availability: The substitute part demonstrates higher stock levels (1244 units versus 697 units), ensuring sustained procurement capability.

Functional Equivalence: All mechanical, electrical, and material specifications are identical between the two parts, confirming direct interchangeability without design modification or system re-qualification.

Packaging: The substitute is supplied in bulk packaging, suitable for production and assembly environments.

Frequently Asked Questions (FAQ)

Q: Are the 206478-4 and 5206478-4 mechanically interchangeable?

A: Yes. Both parts are 37-position hinged backshells from the AMPLIMITE HD-20 series with identical shell size C, cable exit angles (45°, 180°), and hardware specifications (4-40 mating screws). They are direct mechanical equivalents.

Q: What is the primary reason to substitute the 206478-4?

A: The 206478-4 is obsolete. The 5206478-4 is an active product with current manufacturing support, higher inventory availability, and improved regulatory compliance (RoHS compliant, REACH Unaffected).

Q: Will the 5206478-4 work with existing 37-position D-Sub connectors designed for the 206478-4?

A: Yes. Both parts are compatible with 37-position and HD62-position D-Sub connectors with shell size C. No connector redesign or modification is required.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are unshielded backshells with identical electrical properties. Performance in signal integrity and EMI characteristics is equivalent.

Q: What is the difference in packaging between these parts?

A: The 206478-4 packaging is not specified in available documentation. The 5206478-4 is supplied in bulk packaging, which is standard for production environments.

Q: Can the 5206478-4 be used in applications requiring RoHS compliance?

A: Yes. The 5206478-4 is RoHS compliant, making it suitable for applications with environmental and regulatory compliance requirements. The original 206478-4 is non-compliant.

Q: Are both parts suitable for unlimited moisture exposure?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the cable exit angle specification for both parts?

A: Both parts support 45° and 180° cable exit angles, providing flexibility for various cable routing configurations in D-Sub connector assemblies.
