Key Parameters

Substitute Part Grouping Explanation

Substitution of the 555057-1 is based on strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Requirements:

• Connector Type: Receptacle (50 positions, 2 rows)
• Mounting Configuration: Panel Mount, Through Hole, Right Angle
• Termination Method: Solder
• Connector Style: Outer Shroud Contacts
• Series Classification: CHAMP .085
• Flange Feature: Housing/Shell (4-40)
• Contact Finish: Gold
• Shielding: Shielded construction

The substitute part 5555057-1 maintains full compatibility across all specified electrical and mechanical parameters. Both connectors share identical position count, row configuration, mounting type, termination method, and contact interface specifications. The substitute part is derived from the same base product family (CHAMP .085 series) and maintains the same flange and shielding characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5555057-1

The 5555057-1 is the direct substitute for the obsolete 555057-1. This part maintains complete electrical and mechanical compatibility across all critical interface parameters. The substitute part is currently in Active product status with 953 units available in inventory.

Compliance Advantages:

The 5555057-1 achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The original 555057-1 is RoHS non-compliant. For new designs, system upgrades, or applications subject to environmental regulations, the 5555057-1 provides compliance alignment while maintaining full functional equivalence.

Feature Enhancement:

The substitute part includes an additional Board Lock feature in addition to the Bail Lock mechanism present on the original part. This enhancement provides improved retention characteristics without affecting electrical or mechanical compatibility.

Contact Finish Specification:

The 5555057-1 specifies contact finish thickness at 30.0µin (0.76µm), providing documented gold plating specification. Both parts maintain gold contact finish for equivalent electrical performance and corrosion resistance.

Frequently Asked Questions (FAQ)

Q: Can the 5555057-1 be used as a direct replacement for the 555057-1 in existing applications?

A: Yes. The 5555057-1 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, mounting configuration, termination method, and contact interface. The substitute part is fully compatible with applications originally designed for the 555057-1.

Q: What is the difference between the Bail Lock feature on the original part and the Bail Lock plus Board Lock features on the substitute?

A: The original 555057-1 includes Bail Lock retention. The substitute 5555057-1 includes both Bail Lock and Board Lock features. The Board Lock provides additional mechanical retention to the printed circuit board. This enhancement does not affect electrical compatibility or mechanical interface dimensions.

Q: Does the RoHS3 compliance of the 5555057-1 affect compatibility with the 555057-1?

A: No. RoHS3 compliance is an environmental and regulatory certification that does not alter electrical or mechanical performance. The 5555057-1 maintains identical functional specifications while meeting current environmental standards. For applications subject to RoHS requirements, the 5555057-1 is the appropriate selection.

Q: Are there packaging differences between the 555057-1 and 5555057-1?

A: The 555057-1 packaging is listed as unspecified. The 5555057-1 is supplied in Tray packaging. Both parts are identical in connector specifications and electrical performance. Packaging format does not affect connector functionality or compatibility.

Q: What is the contact finish thickness specification for the 555057-1?

A: The contact finish thickness for the 555057-1 is not specified in the available documentation. The 5555057-1 specifies contact finish thickness at 30.0µin (0.76µm). Both parts maintain gold contact finish for equivalent electrical performance.

Q: Is the 5555057-1 currently available for procurement?

A: Yes. The 5555057-1 is in Active product status with 953 units available in inventory. The original 555057-1 is Obsolete with 1147 units available in inventory.

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

A: Both the 555057-1 and 5555057-1 carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
