Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 552003-1 is determined by strict equivalence across the following critical parameters:

• Number of Positions: 50 position configuration
• Cable Exit Angle: 180° orientation
• Shielding Configuration: Unshielded design
• Cable Type: Round cable compatibility
• Accessory Classification: Two piece backshell construction
• Primary Material: Plastic housing
• Hardware Integration: Strain relief provision
• Color Specification: Black finish

The substitute part 552008-1 maintains full equivalence across all these parameters, ensuring direct functional and mechanical compatibility with applications originally specified for the 552003-1. Both parts belong to the CHAMP series and share identical electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The 552008-1 serves as the direct active production equivalent for the obsolete 552003-1. Both components maintain identical functional specifications across all critical electrical and mechanical parameters required for D-Sub backshell applications.

Product Status Consideration: The 552003-1 is classified as obsolete, while the 552008-1 maintains active product status with confirmed inventory availability (885 pcs in stock). This status differential establishes the 552008-1 as the current production standard for new designs and ongoing supply requirements.

Compliance Advantage: The 552008-1 carries ROHS3 compliance certification, whereas the 552003-1 is marked as not applicable. For applications subject to RoHS regulatory requirements, the 552008-1 provides documented compliance assurance.

Material Specification: While both parts employ plastic housing, the 552008-1 specifies Polyphenylene Oxide (PPO) material composition, compared to the generic thermoplastic designation of the 552003-1. PPO material provides enhanced thermal and chemical resistance characteristics within the plastic material category.

Export Classification: Both parts share identical ECCN classification (EAR99), confirming equivalent export control status.

Frequently Asked Questions (FAQ)

Q: Can the 552008-1 directly replace the 552003-1 in existing designs?

A: Yes. The 552008-1 maintains full equivalence across all specified electrical and mechanical parameters, including 50 position count, 180° cable exit angle, unshielded configuration, round cable type, two-piece backshell construction, strain relief hardware, and black color finish. Direct substitution is supported without design modification.

Q: What is the material difference between these two parts?

A: The 552003-1 uses thermoplastic material, while the 552008-1 specifies Polyphenylene Oxide (PPO). Both are plastic materials meeting the primary material requirement. PPO offers enhanced thermal and chemical resistance properties within the plastic category.

Q: Does the 552008-1 meet RoHS requirements?

A: Yes. The 552008-1 carries ROHS3 compliance certification. The 552003-1 is marked as not applicable for RoHS status. For applications requiring RoHS compliance documentation, the 552008-1 is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The 552003-1 packaging specification is not provided in the technical data. The 552008-1 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the current availability status?

A: The 552003-1 is obsolete with 1041 pcs reported in stock. The 552008-1 is active production status with 885 pcs in stock. For new orders and ongoing supply, the 552008-1 is the recommended selection.

Q: Are both parts in the same CHAMP series?

A: Yes. Both the 552003-1 and 552008-1 belong to the TE Connectivity AMP Connectors CHAMP series, confirming series-level compatibility and design consistency.

Q: What export control classification applies to these parts?

A: Both parts carry identical ECCN classification EAR99, confirming equivalent export control status and regulatory treatment.
