TE Connectivity 5-554720-1 Modular Connector RJ45 Plug Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5-554720-1 is an unshielded modular connector plug designed for 8-position 8-contact (8P8C) RJ45 Ethernet applications. This connector accommodates flat oval cable with solid wires and utilizes IDC (Insulation Displacement Contact) termination technology. The part is currently active in production with 895 units in stock.

Substitute parts become necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when alternative manufacturers offer equivalent electrical and mechanical performance. The 5-554720-3 variant has been discontinued at DiGi Electronics, making substitute identification critical for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5-554720-1 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Connector type: Plug
• Contact configuration: 8P8C (RJ45, Ethernet)
• Termination method: IDC
• Shielding: Unshielded
• Housing material: Polycarbonate (PC)
• Contact material: Phosphor Bronze
• Contact finish: Gold plating
• Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Factors:

• Physical length tolerance: 0.850" ± acceptable mechanical variance
• Wire gauge range: 24-26 AWG
• Cable type: Flat oval or round cable with solid wires
• Color: Translucent clear housing

The identified substitutes meet these core electrical and mechanical requirements, enabling direct functional replacement in 8P8C RJ45 Ethernet plug applications with IDC termination.

Parameter Comparison

Engineering Selection Recommendations

5-554720-3 (TE Connectivity AMP Connectors): This part is a direct TE Connectivity variant with identical electrical and mechanical specifications to the 5-554720-1. However, this part number has been discontinued at DiGi Electronics, limiting long-term procurement viability. Selection of this substitute is appropriate only for short-term applications or when existing inventory is available. RoHS status is listed as not applicable, which may present compliance concerns for new designs requiring RoHS certification.

940-SP-3088R-A133 (Stewart Connector): This substitute offers full functional equivalence for 8P8C RJ45 IDC plug applications. The part is currently active with substantial inventory availability (91,666 units). Key differences include cable type accommodation (round cable with solid or stranded wires versus flat oval cable) and a slightly longer physical length (0.885" versus 0.850"). The Stewart Connector part carries ROHS3 compliance certification and provides explicit voltage (150V) and current (1.5 A) ratings. This part is suitable for new designs and ongoing production requiring long-term supply assurance and current regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5-554720-3 be used as a direct replacement for the 5-554720-1?

A: Yes, the 5-554720-3 provides direct functional equivalence with identical electrical and mechanical specifications. However, this part has been discontinued at DiGi Electronics, making it unsuitable for applications requiring long-term supply continuity.

Q: What is the primary difference between the 940-SP-3088R-A133 and the 5-554720-1?

A: The Stewart Connector 940-SP-3088R-A133 accommodates round cable with solid or stranded wires, whereas the TE Connectivity 5-554720-1 is designed for flat oval cable with solid wires. The Stewart part is also 0.035" (0.89mm) longer. Both parts maintain identical 8P8C RJ45 IDC plug functionality and contact specifications.

Q: Is the 940-SP-3088R-A133 compatible with flat oval cable applications?

A: The 940-SP-3088R-A133 is specified for round cable. While physical insertion may be possible, the connector is engineered for round cable geometry. Flat oval cable use with this part falls outside the specified design parameters.

Q: What compliance certifications apply to each substitute?

A: The 5-554720-1 carries RoHS Compliant certification. The 5-554720-3 lists RoHS status as not applicable. The 940-SP-3088R-A133 carries ROHS3 Compliant certification and REACH Unaffected status. All three parts are classified as EAR99 for export control purposes.

Q: Does the 940-SP-3088R-A133 provide electrical ratings?

A: Yes, the Stewart Connector part specifies 150V voltage rating and 1.5 A current rating. The TE Connectivity parts do not provide explicit electrical ratings in their specifications.

Q: Which substitute offers the best long-term supply availability?

A: The 940-SP-3088R-A133 offers the highest inventory level (91,666 units) and active product status, providing superior long-term procurement assurance compared to the discontinued 5-554720-3 or the primary 5-554720-1.

Q: Are all three parts suitable for Cat5 Ethernet applications?

A: The 5-554720-1 and 5-554720-3 are explicitly rated for Cat5. The 940-SP-3088R-A133 does not specify a Cat rating but maintains 8P8C RJ45 IDC plug functionality compatible with standard Ethernet cabling.
