TE Connectivity AMP Connectors 5-557965-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5-557965-3 is a modular plug connector with 6 positions and 4 contacts (6p4c), conforming to RJ11 and RJ14 standards. This unshielded connector is designed for flat oval cable with solid wires and utilizes IDC (Insulation Displacement Contact) termination technology. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5-557965-3 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector type must be Plug
• Position and contact configuration must be 6p4c (RJ11, RJ14)
• Shielding must be Unshielded
• Termination method must be IDC
• Housing material must be Polycarbonate (PC)
• Contact material must be Phosphor Bronze with gold finish

Secondary Compatibility Factors:

• Cable type compatibility with flat oval cable
• Physical length tolerance within connector specifications
• RoHS and environmental compliance status

The Stewart Connector 940-SP-3046 meets all primary substitution criteria and is classified as a direct equivalent for the discontinued TE Connectivity part.

Parameter Comparison

Engineering Selection Recommendations

The Stewart Connector 940-SP-3046 is the direct equivalent substitute for the discontinued TE Connectivity 5-557965-3. Both connectors share identical core specifications: 6p4c configuration, unshielded design, IDC termination, polycarbonate housing, and phosphor bronze gold-plated contacts.

Compliance Status: The Stewart Connector part maintains ROHS3 compliance, exceeding the RoHS compliance of the original part. Both parts carry EAR99 ECCN classification and share identical HTSUS codes, confirming regulatory equivalence.

Availability Advantage: The Stewart Connector 940-SP-3046 is currently in active production with 31,108 pieces in stock, compared to the discontinued status of the TE Connectivity part.

Physical Compatibility: The length differential of 0.005" (0.12mm) between the two connectors falls within standard manufacturing tolerances for modular connectors and does not affect functional compatibility with standard RJ11/RJ14 applications.

Wire Gauge Flexibility: The Stewart Connector part accommodates both solid and stranded wires, providing broader cable compatibility than the original part specification of solid wires only.

Frequently Asked Questions (FAQ)

Q: Can the Stewart Connector 940-SP-3046 directly replace the TE Connectivity 5-557965-3 in existing applications?

A: Yes. Both connectors meet identical specifications for 6p4c RJ11/RJ14 modular plug configuration, unshielded design, IDC termination, and contact materials. The physical length difference of 0.005" is within standard connector tolerances and does not affect mating or performance.

Q: What is the significance of the Stewart Connector part accepting both solid and stranded wires?

A: The Stewart Connector 940-SP-3046 specification permits both solid and stranded wire types, while the original TE Connectivity part specifies solid wires only. This provides design flexibility for applications using either wire construction without requiring different connector models.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The Stewart Connector part carries ROHS3 certification, which represents a more current compliance standard than the RoHS compliance of the TE Connectivity part. Both parts are classified as REACH Unaffected or Vendor Undefined, and both carry EAR99 ECCN designation.

Q: What are the electrical ratings for the Stewart Connector substitute?

A: The Stewart Connector 940-SP-3046 is rated for 1.5 A current and 150V voltage. The original TE Connectivity part does not specify these ratings in the available documentation.

Q: Does the packaging format differ between the two parts?

A: The TE Connectivity part packaging is not specified in available documentation. The Stewart Connector 940-SP-3046 is supplied in bulk packaging, which is standard for modular connector components.

Q: Are there any wire gauge restrictions for the Stewart Connector part?

A: Wire gauge specifications are not provided in the Stewart Connector documentation. The original TE Connectivity part specifies 26-28 AWG compatibility. For applications requiring specific wire gauge confirmation, consult the detailed product specifications from Stewart Connector.
