Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5-557963-3 is determined by strict alignment with the following core parameters:

Primary Substitution Criteria:

• Connector type: Plug
• Contact configuration: 10p10c (RJ50)
• Shielding: Unshielded
• Termination: IDC
• Housing material: Polycarbonate (PC)
• Contact finish: Gold
• Color: Translucent - Clear
• Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Factors:

• Cable type compatibility (round or flat oval stranded wire configurations)
• Contact material (Phosphor Bronze or Copper Alloy)
• Physical length tolerance
• Wire gauge range support

The identified substitute parts meet all primary substitution criteria. Variations in cable type, contact material, and electrical ratings are documented to enable informed selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Stewart Connector 937-SP-301010R

This substitute part is classified as active and ROHS3 compliant. It maintains identical contact configuration, shielding, termination method, and housing material specifications. The physical length differential of 0.010" (0.25mm) is within typical mechanical tolerance ranges for modular connector applications. The phosphor bronze contact material matches the original specification. This part is suitable for direct replacement in applications where the original TE Connectivity component is no longer available.

Assmann WSW A-MO 10/10-F50

This substitute part is classified as active and ROHS3 compliant. It meets all primary substitution criteria with identical contact configuration, shielding, termination method, and housing material. The cable type differs from the original specification (flat oval versus round), which may affect mechanical fit in existing cable assemblies. The copper alloy contact material provides equivalent electrical performance. The physical length is 0.081" (2.06mm) longer than the original part. This part is suitable for applications where flat oval cable compatibility is acceptable or preferred.

Both substitute parts provide REACH compliance status and maintain the same ECCN and HTSUS classifications as the original component.

Frequently Asked Questions (FAQ)

Q: Can the Stewart Connector 937-SP-301010R directly replace the TE Connectivity 5-557963-3 in existing assemblies?

A: Yes. Both parts share identical connector type, contact configuration (10p10c RJ50), shielding (unshielded), termination method (IDC), housing material (polycarbonate), and contact finish specifications. The 0.010" length difference is within standard mechanical tolerances for modular connector applications.

Q: What is the primary difference between the Stewart Connector and Assmann WSW substitute options?

A: The Stewart Connector 937-SP-301010R is designed for round cable with stranded wires, matching the original cable type specification. The Assmann WSW A-MO 10/10-F50 is designed for flat oval cable with stranded wires. Both maintain identical electrical and mechanical interface specifications for the connector plug itself.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the Stewart Connector 937-SP-301010R and Assmann WSW A-MO 10/10-F50 are ROHS3 compliant. The original TE Connectivity part has a status of "Not applicable" for RoHS compliance.

Q: What are the voltage and current ratings for the substitute parts?

A: The Stewart Connector 937-SP-301010R is rated for 150V and 1.5 A. The Assmann WSW A-MO 10/10-F50 is rated for 250V and 2 A. The original TE Connectivity part does not specify voltage or current ratings in the available documentation.

Q: Do the substitute parts have the same contact material as the original?

A: The Stewart Connector 937-SP-301010R uses phosphor bronze contacts, matching the original specification. The Assmann WSW A-MO 10/10-F50 uses copper alloy contacts. Both materials provide equivalent electrical performance with gold finish plating at 50.0µin thickness.

Q: Are there any compliance or regulatory differences between the parts?

A: All three parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. Both substitute parts are REACH unaffected. The original part has undefined REACH status. All parts maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What inventory availability exists for these substitute parts?

A: The Stewart Connector 937-SP-301010R has 35,183 pieces in stock. The Assmann WSW A-MO 10/10-F50 has 1,614 pieces in stock. The original TE Connectivity part has 684 pieces listed as new original in stock but is classified as obsolete.
