Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 552073-6 is determined by alignment across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 36
• Accessory Type: Two Piece Backshell
• Cable Exit Angle: 180°
• Cable Type: Round
• Series: CHAMP
• Primary Material: Plastic
• Hardware: Strain Relief
• Color: Black

Variable Parameters Permitting Substitution:

• Shielding Configuration: The substitute part may differ in shielding characteristics while maintaining all other functional parameters
• Material Composition: Polyphenylene Oxide (PPO) is acceptable as an alternative to Polyphenylene (PPE) within the plastic material category
• Product Status: Active status is preferred over Obsolete status for ongoing availability

The substitute part 554945-1 maintains all mandatory matching parameters while introducing shielded configuration and alternative material composition, making it a valid functional equivalent for applications where electromagnetic shielding is required or beneficial.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using 552073-6:

The substitute part 554945-1 is available as an active production equivalent. Both parts maintain identical mechanical and electrical specifications across all critical parameters including position count, cable exit geometry, strain relief hardware, and material category classification.

The primary distinction between these parts is the shielding configuration. The 554945-1 provides electromagnetic shielding, which is beneficial in environments with electromagnetic interference or where signal integrity is a design consideration. The unshielded 552073-6 is suitable for applications without such requirements.

Both parts maintain equivalent compliance certifications: ROHS3/RoHS compliance and EAR99 export classification. Both carry MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture handling requirements during storage or assembly.

The 554945-1 is manufactured from Polyphenylene Oxide (PPO) rather than Polyphenylene (PPE), representing a material variant within the plastic polymer category that maintains functional equivalence for backshell applications.

Selection between these parts should be based on whether electromagnetic shielding is required for the specific application. The 554945-1 is recommended for new designs and ongoing production due to its Active product status and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 554945-1 be used as a direct replacement for 552073-6?

A: The 554945-1 is mechanically and electrically compatible with applications designed for the 552073-6. Both parts share identical position count (36), cable exit angle (180°), connector series (CHAMP), and strain relief hardware. The primary difference is the addition of electromagnetic shielding in the 554945-1. Compatibility depends on whether the application requires or can accommodate shielded configuration.

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

A: The 552073-6 is unshielded, while the 554945-1 includes electromagnetic shielding. Shielding provides protection against electromagnetic interference and improves signal integrity in noise-sensitive applications. In environments without significant electromagnetic interference, either configuration is functionally equivalent. The choice depends on application-specific requirements.

Q: Are there material differences between these backshells?

A: Yes. The 552073-6 uses Polyphenylene (PPE) while the 554945-1 uses Polyphenylene Oxide (PPO). Both are plastic polymers suitable for D-Sub backshell applications. PPO offers comparable mechanical and thermal properties to PPE in this application context. Both materials maintain the same color (Black) and strain relief functionality.

Q: Why is 552073-6 listed as Obsolete?

A: The 552073-6 carries Obsolete product status, indicating it is no longer manufactured by TE Connectivity. The 554945-1 is the active production equivalent, ensuring continued availability for new orders and ongoing production requirements.

Q: Do both parts have the same compliance certifications?

A: Both parts are RoHS compliant (552073-6 is ROHS3 Compliant; 554945-1 is RoHS Compliant). Both carry EAR99 export classification and identical HTSUS codes (8538.90.8180). Both have MSL Level 1 (Unlimited) moisture sensitivity ratings, requiring no special moisture handling during storage or assembly.

Q: What is the packaging difference?

A: The 552073-6 packaging is not specified in available documentation. The 554945-1 is supplied in Bag packaging. This difference does not affect functional compatibility but may impact receiving, storage, and handling procedures.

Q: Are there inventory considerations for selecting between these parts?

A: Both parts maintain substantial inventory levels (552073-6: 1085 Pcs; 554945-1: 1053 Pcs). Both are listed as New Original In Stock. Inventory availability is not a limiting factor in the selection decision.
