Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 555764-1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector type (Jack)
• Contact count and configuration (8p8c RJ45 Ethernet)
• Shielding classification (Unshielded)
• Category rating (Cat3)
• Contact material and finish specifications (Phosphor Bronze, Gold 50.0µin)

Mechanical Parameters:

• Orientation (90° right-angle)
• Mounting method (Surface Mount)
• Termination type (Solder)
• Housing material (Polyamide/Nylon)
• Tab direction (Down)
• Operating temperature range (-40°C ~ 85°C)

Functional Features:

• Board Lock capability
• Solder Retention

Parts meeting all these criteria are classified as direct substitutes. Variations in packaging format, product status, or compliance certifications do not affect functional interchangeability when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5555764-1 is a direct functional equivalent to the 555764-1 across all electrical and mechanical parameters. Both connectors are identical in connector type, contact configuration, orientation, mounting method, termination type, shielding, and operating specifications.

Product Status Consideration: The 555764-1 carries Obsolete status, while the 5555764-1 is Active. For new designs or ongoing production requiring long-term supply assurance, the 5555764-1 is the appropriate selection.

Compliance Consideration: The 5555764-1 is ROHS3 Compliant, whereas the 555764-1 is RoHS non-compliant. Applications subject to RoHS regulations or customer requirements mandating RoHS compliance must use the 5555764-1.

Packaging Consideration: The 5555764-1 is supplied in Tray packaging. Verify packaging format compatibility with receiving, storage, and assembly processes.

Both parts are suitable for Cat3 Ethernet applications with identical electrical performance and mechanical fit. Selection between them is determined by product status requirements, regulatory compliance mandates, and packaging specifications.

Frequently Asked Questions (FAQ)

Q: Are the 555764-1 and 5555764-1 electrically interchangeable?

A: Yes. Both connectors are 8p8c (RJ45, Ethernet) jacks with identical contact material (Phosphor Bronze), contact finish (Gold, 50.0µin), and Cat3 rating. Electrical performance is equivalent.

Q: Can the 5555764-1 be used as a direct replacement for the 555764-1 in existing designs?

A: Yes. All electrical and mechanical parameters are identical, including connector type, orientation (90° right-angle), mounting method (Surface Mount), termination (Solder), shielding (Unshielded), and operating temperature range (-40°C ~ 85°C). Physical fit and functional performance are equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (555764-1 is Obsolete; 5555764-1 is Active), RoHS compliance (555764-1 is non-compliant; 5555764-1 is ROHS3 Compliant), and packaging format (5555764-1 is supplied in Tray). Functional specifications are identical.

Q: Which part should be selected for new production?

A: The 5555764-1 is recommended for new production due to its Active product status and ROHS3 compliance. The Obsolete status of the 555764-1 indicates limited future availability.

Q: Does packaging format affect connector performance?

A: No. Packaging format (Tray for the 5555764-1) affects logistics, storage, and assembly handling but does not alter electrical or mechanical performance. Verify packaging compatibility with your receiving and assembly processes.

Q: Are both connectors suitable for Cat3 Ethernet applications?

A: Yes. Both the 555764-1 and 5555764-1 are rated for Cat3 and are functionally equivalent for Ethernet jack applications.

Q: What is the operating temperature range for these connectors?

A: Both connectors operate across -40°C to 85°C, providing equivalent thermal performance for industrial and commercial applications.

Q: Is RoHS compliance a factor in selecting between these parts?

A: Yes, if your application or customer requirements mandate RoHS compliance. The 5555764-1 is ROHS3 Compliant, while the 555764-1 is RoHS non-compliant. Regulatory or contractual obligations may require use of the 5555764-1.
