Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 554346-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (36)
• Number of rows (2)
• Mounting configuration (Panel Mount)
• Termination method (IDC)
• Connector style (Outer Shroud Contacts)
• Series designation (CHAMP .085)
• Features (Bail Lock, Shielded)
• Contact finish (Gold)
• Flange feature (Board Side 4-40)

The substitute part 5554346-2 maintains complete equivalence across all these parameters, with the primary distinction being packaging format and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 5554346-2 serves as a direct functional equivalent to the 554346-2 across all electrical and mechanical specifications. Both parts are classified as obsolete products within the CHAMP .085 series.

Compliance Considerations:

The 5554346-2 provides improved regulatory compliance status compared to the main part. The substitute achieves ROHS3 compliance and REACH Unaffected status, whereas the 554346-2 is RoHS non-compliant with vendor-undefined REACH status. For applications subject to environmental regulations or procurement policies requiring RoHS compliance, the 5554346-2 is the appropriate selection.

Packaging and Availability:

The 5554346-2 is supplied in tray packaging with higher current inventory availability (1659 units versus 1116 units). The packaging format difference does not affect connector functionality or performance.

Contact Finish Specification:

The 5554346-2 provides explicit contact finish thickness specification (30.0µin / 0.76µm), whereas the main part does not document this parameter. Both maintain gold contact finish.

Frequently Asked Questions (FAQ)

Q: Are the 554346-2 and 5554346-2 electrically and mechanically interchangeable?

A: Yes. Both connectors maintain identical specifications across connector type, position count, row configuration, mounting method, termination technology, contact style, series designation, features, and contact finish material. They are direct functional equivalents.

Q: What is the primary difference between these two part numbers?

A: The primary differences are packaging format (tray for the 5554346-2), regulatory compliance status (ROHS3 compliant versus non-compliant), and REACH classification (REACH Unaffected versus Vendor Undefined). Electrical and mechanical performance are identical.

Q: Should I select the 5554346-2 over the 554346-2 for new designs?

A: Selection depends on regulatory requirements applicable to your application. If RoHS compliance is mandated, the 5554346-2 is required. If no compliance requirements apply, either part functions identically.

Q: Does the tray packaging of the 5554346-2 affect installation or performance?

A: No. Packaging format is a logistics and handling consideration only. It does not affect connector electrical performance, mechanical fit, or operational characteristics.

Q: Are both parts still in production?

A: Both parts are classified as obsolete. Current availability is limited to existing inventory stock. The 5554346-2 currently has higher inventory availability (1659 units).

Q: What does IDC termination mean for this connector?

A: IDC (Insulation Displacement Contact) termination allows direct connection to flat ribbon cable without stripping insulation. The connector pierces the cable insulation to establish electrical contact.

Q: Can I use the 554346-2 in applications requiring RoHS compliance?

A: No. The 554346-2 is RoHS non-compliant. Applications with RoHS compliance requirements must use the 5554346-2.
