Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 552073-5 is determined by the following critical parameters that must remain consistent across equivalent parts:

Mandatory Matching Parameters:

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

Variable Parameters Permitting Substitution:

• Shielding: The substitute part may differ in shielding configuration (Unshielded to Shielded)
• Material Composition: The substitute part may utilize alternative plastic formulations (PPE to PPO)
• Product Status: The substitute part may have Active status despite the main part being Obsolete
• RoHS Compliance Level: The substitute part may have updated RoHS certification (ROHS3 to RoHS Compliant)

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

Parameter Comparison

Engineering Selection Recommendations

For 552073-5 Replacement:

The substitute part 554945-1 is available as an active production component from the same manufacturer and series. Selection between the main part and substitute should be based on the following criteria:

Select 552073-5 (Unshielded Configuration) when:

• Applications operate in electromagnetically benign environments
• Unshielded backshell configuration is specified in system design documentation
• Cost optimization for unshielded applications is a requirement

Select 554945-1 (Shielded Configuration) when:

• Applications require electromagnetic shielding for signal integrity
• System design specifications call for shielded backshell assemblies
• Long-term component availability is a priority (Active product status)
• Updated RoHS compliance certification is required for new designs

Both parts maintain identical mechanical compatibility, position count, cable exit angle, and strain relief hardware. The material composition variation (PPE to PPO) and shielding difference represent the primary functional distinctions between these components.

Frequently Asked Questions (FAQ)

Q: Can 554945-1 be used as a direct replacement for 552073-5?

A: The 554945-1 is mechanically and electrically compatible with 552073-5 for all 36-position, 180° cable exit applications within the CHAMP series. The primary difference is the addition of shielding in 554945-1. Direct substitution is permissible when shielded configuration is acceptable or required by the application.

Q: What is the functional difference between the unshielded 552073-5 and shielded 554945-1?

A: The 552073-5 provides basic strain relief and cable management without electromagnetic shielding. The 554945-1 incorporates shielding to attenuate electromagnetic interference. Both maintain identical mechanical interfaces, position counts, and cable exit geometry.

Q: Are there material compatibility concerns between PPE and PPO plastic formulations?

A: Both Polyphenylene (PPE) and Polyphenylene Oxide (PPO) are engineering-grade thermoplastics suitable for D-Sub backshell applications. The material variation between 552073-5 and 554945-1 does not create compatibility issues with standard D-Sub connector systems.

Q: Why is 552073-5 listed as Obsolete?

A: The 552073-5 carries Obsolete product status, indicating it is no longer in active production. The 554945-1 remains in active production and serves as the current equivalent offering from TE Connectivity AMP Connectors for 36-position, 180° cable exit backshell applications.

Q: Are both parts RoHS compliant?

A: Yes. The 552073-5 is ROHS3 Compliant, and the 554945-1 is RoHS Compliant. Both parts meet regulatory requirements for hazardous substance restrictions.

Q: What is the inventory status for these parts?

A: The 552073-5 has 717 pieces in stock as new original inventory. The 554945-1 has 1053 pieces in stock as new original inventory, packaged in bags.

Q: Do both parts have identical moisture sensitivity levels?

A: Yes. Both the 552073-5 and 554945-1 have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or installation.
