Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 555149-3 and equivalent part 5555149-3 is determined by electrical and mechanical parameter compatibility. Both parts maintain identical specifications across the following critical parameters:

• Connector type: Receptacle
• Position count: 50 positions in 2 rows
• Mounting configuration: Through-hole, right-angle orientation
• Termination method: Solder
• Connector style: Outer shroud contacts
• Series designation: CHAMP .085
• Contact finish and thickness: Gold, 30.0µin (0.76µm)
• Features: Bail lock, board lock, shielded
• Flange specification: Housing/Shell (4-40)
• Moisture sensitivity: MSL 1 (Unlimited)

The primary difference between these parts is packaging format and regulatory compliance status. The 555149-3 is supplied in standard packaging with RoHS non-compliant status, while the 5555149-3 is supplied in tray packaging with ROHS3 compliance. The 555149-3 includes panel mount capability, whereas the 5555149-3 specifies through-hole mounting only.

Parameter Comparison

Engineering Selection Recommendations

Selection between 555149-3 and 5555149-3 is determined by application requirements and regulatory constraints:

Select 555149-3 when:

• Panel mount capability is required for the application
• RoHS non-compliant components are acceptable for the end product
• Standard packaging meets procurement specifications
• Through-hole and panel mount mounting flexibility is needed

Select 5555149-3 when:

• ROHS3 compliance is mandated by product specifications or customer requirements
• Tray packaging is compatible with assembly and logistics processes
• Through-hole mounting configuration is sufficient for the application
• Panel mount capability is not required

Both parts maintain identical electrical and mechanical specifications for the 50-position D-Sub receptacle connector function. The choice between these parts is driven by regulatory compliance status and mounting configuration requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are 555149-3 and 5555149-3 electrically interchangeable?

A: Yes. Both parts are 50-position D-Sub receptacle connectors with identical electrical specifications, including contact finish, contact finish thickness, and connector style. They function identically in solder termination applications.

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

A: The primary differences are packaging format and regulatory compliance. The 555149-3 uses standard packaging and is RoHS non-compliant, while the 5555149-3 uses tray packaging and is ROHS3 compliant. Additionally, the 555149-3 supports both panel mount and through-hole mounting, whereas the 5555149-3 specifies through-hole mounting only.

Q: Can 5555149-3 be used as a direct replacement for 555149-3 in a panel mount application?

A: No. The 5555149-3 is specified for through-hole mounting only and does not include panel mount capability. If panel mount functionality is required, the 555149-3 must be used.

Q: Which part should be selected for a new design requiring RoHS compliance?

A: The 5555149-3 should be selected, as it carries ROHS3 compliance certification. The 555149-3 is RoHS non-compliant and is not suitable for applications with RoHS compliance requirements.

Q: Are the mounting hole specifications identical between these parts?

A: Both parts feature Housing/Shell (4-40) flange specifications and are designed for through-hole, right-angle solder termination. The 555149-3 additionally supports panel mount configuration.

Q: What is the moisture sensitivity level for both parts?

A: Both the 555149-3 and 5555149-3 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts currently available in inventory?

A: Yes. The 555149-3 has 794 units in stock, and the 5555149-3 has 773 units in stock, both listed as new original components.
