Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 557101-5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 40
• Number of Rows: 2
• Connector Type: Receptacle
• Mounting Type: Through Hole, Right Angle
• Termination Method: Solder
• Connector Style: Outer Shroud Contacts
• Features: Board Lock
• Contact Finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts maintain these specifications while offering active product status and improved compliance certifications. Substitutes are sourced from TE Connectivity AMP Connectors and Amphenol ICC (FCI) manufacturers, both established suppliers within the D-Sub, D-Shaped Connectors category.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity AMP Connectors 1734037-4

The 1734037-4 is the direct substitute for the obsolete 557101-5. Both parts are manufactured by TE Connectivity AMP Connectors within the CHAMP .050 I series. The 1734037-4 maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. This part is the preferred selection for applications requiring continuity with the original design intent and manufacturer lineage.

Secondary Recommendation: Amphenol ICC (FCI) PHEC40R-R211LF

The PHEC40R-R211LF provides functional equivalence across all critical parameters. This part is manufactured by Amphenol ICC (FCI) within the PHEC series and maintains active product status. Selection of this alternative is appropriate when supply chain diversification or secondary sourcing is required. Contact finish thickness differs at 10.0µin (0.25µm) compared to the main part specification of 30.0µin (0.76µm), representing a thinner gold plating layer.

Both substitute parts satisfy the mandatory parameter requirements for direct replacement in board-to-board receptacle applications with 40-position, 2-row configurations, right-angle through-hole mounting, and solder termination.

Frequently Asked Questions (FAQ)

Q: Can the 1734037-4 be used as a direct replacement for the 557101-5?

A: Yes. The 1734037-4 maintains identical specifications across all critical parameters including position count, row configuration, connector type, mounting orientation, termination method, and contact finish material. Both parts are manufactured by TE Connectivity AMP Connectors within the same CHAMP .050 I series.

Q: What is the primary difference between the 557101-5 and its substitutes?

A: The 557101-5 is classified as obsolete with RoHS non-compliant status. The 1734037-4 substitute offers active product status and ROHS3 compliance. The PHEC40R-R211LF substitute also provides active status but is sourced from a different manufacturer (Amphenol ICC/FCI).

Q: Are there packaging differences between the main part and substitutes?

A: The 557101-5 packaging specification is not provided in the technical data. Both substitute parts are supplied in Tray packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: How do the contact finish specifications compare?

A: The 557101-5 specifies gold contact finish at 30.0µin (0.76µm) thickness. The 1734037-4 specifies gold contact finish at Flash thickness. The PHEC40R-R211LF specifies gold contact finish at 10.0µin (0.25µm) thickness. All three parts utilize gold plating; thickness variations reflect different manufacturing specifications.

Q: What is the inventory availability for each part?

A: The 557101-5 has 687 pieces in stock (obsolete status). The 1734037-4 has 2284 pieces in stock (active status). The PHEC40R-R211LF has 1058 pieces in stock (active status).

Q: Are there compliance differences between the parts?

A: The 557101-5 is RoHS non-compliant and REACH Affected. The 1734037-4 is ROHS3 Compliant with REACH status listed as Vendor Undefined. The PHEC40R-R211LF is REACH Affected with RoHS status not specified. All three parts share the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Can the PHEC40R-R211LF be used interchangeably with the TE Connectivity parts?

A: Yes, for applications requiring functional equivalence. The PHEC40R-R211LF maintains all critical electrical and mechanical parameters. However, it is sourced from a different manufacturer (Amphenol ICC/FCI) and represents a cross-manufacturer substitute rather than a direct manufacturer equivalent.
