Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 553811-2 is determined by strict equivalence across all core electrical and mechanical parameters. The substitute part 5553811-2 maintains identical specifications for connector type, position count, row configuration, mounting methodology, termination approach, connector styling, shielding characteristics, contact material and finish, and flange specifications. Both parts belong to the CHAMP .085 series, ensuring mechanical and electrical compatibility.

The primary differentiators between the main part and its substitute are product status (obsolete versus active), packaging format (unspecified versus tray), RoHS compliance status (non-compliant versus ROHS3 compliant), and HTSUS classification. These differences do not affect functional interchangeability in applications where the connector specifications are met.

Parameter Comparison

Engineering Selection Recommendations

The 5553811-2 serves as the direct functional equivalent to the obsolete 553811-2. Selection of the substitute part is appropriate for all applications requiring a 24-position D-Sub receptacle connector with panel mount, through-hole, right-angle solder termination in the CHAMP .085 series.

The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain reliability. Additionally, the 5553811-2 achieves ROHS3 compliance, making it suitable for applications subject to RoHS regulatory requirements. The main part's RoHS non-compliant status may restrict its use in regulated markets and new product designs.

Both parts maintain identical electrical and mechanical specifications, including connector positioning, contact finish, shielding characteristics, and flange configuration. The difference in packaging format (tray for the substitute) does not affect functional performance and represents a standard industry packaging variation.

Frequently Asked Questions (FAQ)

Q: Are the 553811-2 and 5553811-2 electrically and mechanically interchangeable?
