Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 554923-2 with active equivalent components is determined by strict electrical and mechanical parameter matching within the D-Sub receptacle connector category. The primary substitution criteria include:

Electrical Parameters:

• Connector type (Receptacle)
• Number of positions (24)
• Number of rows (2)
• Contact finish material and thickness (Gold, 30.0µin)

Mechanical Parameters:

• Mounting configuration (Panel Mount, Through Hole, Right Angle)
• Termination method (Solder)
• Connector style (Outer Shroud Contacts)
• Series designation (CHAMP .085)
• Features (Board Lock, Shielded)
• Flange specification (Housing/Shell 6-32)

Environmental Parameters:

• Moisture Sensitivity Level (1 - Unlimited)

The substitute part 5554923-2 maintains identical electrical and mechanical specifications while transitioning from obsolete to active product status. Packaging differences (unspecified for main part versus Tray for substitute) do not affect functional compatibility or electrical performance.

Engineering Selection Recommendations

The 5554923-2 serves as the direct active equivalent to the obsolete 554923-2. Selection of the 5554923-2 is supported by the following engineering factors:

Product Status Transition: The 554923-2 is classified as obsolete, while the 5554923-2 maintains active product status. This transition ensures continued availability, technical support, and manufacturing consistency for new designs and production requirements.

Regulatory Compliance: The 5554923-2 achieves RoHS compliance, whereas the 554923-2 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS-compliant components, the 5554923-2 is the appropriate selection.

Functional Equivalence: All electrical and mechanical parameters remain identical between the two parts. The 5554923-2 maintains the same connector configuration, contact specifications, mounting characteristics, and environmental ratings as the obsolete 554923-2, ensuring direct functional substitution without design modification.

Inventory Availability: The 5554923-2 is available in higher inventory quantities (2508 pieces) compared to the 554923-2 (1080 pieces), supporting procurement reliability and lead-time reduction.

Frequently Asked Questions (FAQ)

Q: Can the 5554923-2 be used as a direct replacement for the 554923-2 in existing designs?

A: Yes. The 5554923-2 is electrically and mechanically identical to the 554923-2. All connector specifications, including position count, mounting configuration, termination method, contact finish, and features, are equivalent. No design modifications are required for substitution.

Q: What is the primary difference between the 554923-2 and 5554923-2?

A: The primary differences are product status and RoHS compliance. The 554923-2 is obsolete and RoHS non-compliant, while the 5554923-2 is active and RoHS compliant. Functionally, both parts are identical.

Q: Does the packaging difference (unspecified for 554923-2 versus Tray for 5554923-2) affect compatibility?

A: No. Packaging format does not affect electrical or mechanical compatibility. The packaging difference reflects only the distribution and handling method and does not impact connector performance or installation.

Q: Are there any pin configuration or contact arrangement differences between these parts?

A: No. Both parts maintain identical 24-position, 2-row configurations with outer shroud contacts and the same contact finish specifications (gold, 30.0µin thickness).

Q: Which part should be specified for new designs?

A: The 5554923-2 should be specified for new designs. As the active equivalent with RoHS compliance, it ensures long-term availability, regulatory alignment, and manufacturing support.

Q: Are the mounting and termination methods identical?

A: Yes. Both parts feature panel mount, through-hole, right-angle mounting with solder termination. Installation procedures and PCB layout requirements are identical.

Q: What is the Moisture Sensitivity Level for both parts?

A: Both the 554923-2 and 5554923-2 have a Moisture Sensitivity Level of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
