• Connector style: Outer shroud contacts
• Series designation: CHAMP .085
• Shielding: Present
• Contact finish: Gold at 30.0µin (0.76µm) thickness
• Flange specification: Board side with 6-32 mounting

The substitute part maintains complete functional and physical compatibility with the original part while offering enhanced product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 5554501-2 is the direct substitute for the obsolete 554501-2. Selection of the substitute part is based on the following engineering considerations:

Product Status: The original 554501-2 carries an obsolete designation, limiting long-term availability and support. The substitute 5554501-2 maintains active product status, ensuring continued procurement capability and manufacturer support.

Regulatory Compliance: The substitute part is RoHS compliant, whereas the original part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in many jurisdictions.

Functional Equivalence: All electrical and mechanical parameters are identical between the original and substitute parts. The connector maintains the same 24-position configuration, shielded outer shroud design, gold contact finish, and through-hole solder termination.

Inventory Availability: The substitute part is available in higher quantities (995 pieces) compared to the original part (716 pieces), supporting production continuity.

Packaging Consideration: The substitute part is supplied in tray packaging, which may differ from the original bulk packaging. This packaging change does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 554501-2 and 5554501-2 electrically identical?

A: Yes. Both parts are 24-position D-Sub receptacle connectors with identical electrical specifications, including shielded construction, gold contact finish at 30.0µin thickness, and outer shroud contact style.

Q: What is the primary reason to substitute the 554501-2 with the 5554501-2?

A: The original 554501-2 is classified as obsolete. The 5554501-2 is an active product that provides the same functionality with improved product status and RoHS compliance.
