Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 207473-2 is determined by strict equivalence across the following critical parameters:

Position Count: 37 positions (non-negotiable for connector compatibility)

Shell Size: Size C (mechanical fit requirement)

Compatible D-Sub Sizes: 37pos and HD62pos (interface specification)

Cable Exit Configuration: 90° and 180° dual-angle capability (functional requirement)

Shielding Type: Unshielded (electrical specification)

Material Classification: Plastic construction (primary material category)

Color: Black (specification match)

Hardware Configuration: Assembly Hardware and Strain Relief (functional components)

Cable Type: Round (mechanical specification)

The substitute part 207473-1 maintains identical specifications across all these parameters, differing only in material composition (Polypropylene versus Thermoplastic), packaging format, product status, and regulatory compliance certifications. These differences do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 207473-1

The 207473-1 is the direct functional equivalent of the obsolete 207473-2. Both components share identical specifications for all critical parameters governing D-Sub backshell compatibility: position count, shell size, cable exit angles, shielding configuration, and mechanical interface requirements.

Compliance Advantage: The 207473-1 carries active product status and meets current regulatory requirements. It is ROHS3 compliant and REACH unaffected, whereas the 207473-2 is classified as obsolete with undefined compliance status. For new designs and procurement activities, the 207473-1 is the appropriate selection.

Material Consideration: The 207473-1 specifies Polypropylene (PP) as the material composition, whereas the 207473-2 lists Thermoplastic. Both are plastic polymers suitable for the backshell application. Polypropylene is a well-established thermoplastic material with consistent performance characteristics in connector backshell applications.

Inventory Status: The 207473-1 maintains higher inventory availability (1306 pieces) compared to the 207473-2 (1089 pieces), supporting supply chain reliability for ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can the 207473-1 directly replace the 207473-2 in existing designs?

A: Yes. The 207473-1 maintains identical specifications across all functional and mechanical parameters. The components are mechanically and electrically interchangeable for 37-position D-Sub connector applications.

Q: What is the difference between the Thermoplastic material in 207473-2 and the Polypropylene in 207473-1?

A: Polypropylene is a specific type of thermoplastic polymer. Both materials are plastic-based and suitable for backshell applications. The 207473-1 specifies the material composition more precisely as Polypropylene (PP).

Q: Why is the 207473-2 classified as obsolete?

A: The 207473-2 is no longer in active production. The 207473-1 serves as the current active equivalent and should be used for new procurement and design activities.

Q: Are there any compatibility restrictions when substituting the 207473-1 for the 207473-2?

A: No. Both parts are compatible with 37-position and HD62-position D-Sub connectors, Shell Size C, with identical cable exit angles (90° and 180°) and unshielded configuration.

Q: What is the packaging difference between these parts?

A: The 207473-2 packaging is not specified in the documentation. The 207473-1 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet current regulatory standards?

A: The 207473-1 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 207473-2 has undefined compliance status due to its obsolete classification. For applications requiring current compliance certification, the 207473-1 is the appropriate selection.

Q: Are the cable exit angles identical between both parts?

A: Yes. Both the 207473-2 and 207473-1 support dual cable exit angles of 90° and 180°, providing identical flexibility for cable routing configurations.

Q: What is the moisture sensitivity level for these backshells?

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited moisture tolerance with no special storage or handling requirements.
