TE Connectivity 520250-3 Modular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 520250-3 is a modular jack connector with 6 positions and 6 contacts (6p6c), configured for RJ11, RJ12, RJ14, and RJ25 applications. This connector features a 90° right-angle orientation, through-hole solder termination, and unshielded design rated for Category 3 performance. The 520250-3 is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The substitute part 5520250-3 provides functional equivalence with active product status and improved compliance characteristics.

Substitute Part Grouping Explanation

Substitution between the 520250-3 and 5520250-3 is valid based on identical electrical and mechanical parameters. Both parts share the following critical specifications that determine functional equivalence:

• Connector type: Jack
• Contact configuration: 6p6c (RJ11, RJ12, RJ14, RJ25)
• Mounting method: Through hole
• Orientation: 90° right angle
• Termination: Solder
• Shielding: Unshielded
• Performance rating: Cat3
• Contact material and finish: Phosphor bronze with 50.0µin gold plating
• Housing material: Polybutylene terephthalate (PBT) and polyester
• Operating temperature: -40°C to 85°C
• Mechanical features: Board lock and panel stops

The primary distinction between these parts is product status and compliance certification. The 520250-3 is obsolete with RoHS non-compliant status, while the 5520250-3 is active with RoHS compliant certification. Packaging differs between the two parts, with the 520250-3 supplied in standard packaging and the 5520250-3 supplied in tray packaging.

Parameter Comparison

Engineering Selection Recommendations

The 5520250-3 is the appropriate selection for new designs and production applications. This part maintains complete electrical and mechanical compatibility with the obsolete 520250-3 while offering active product status and RoHS compliance certification. The 5520250-3 is REACH unaffected, providing regulatory advantage over the 520250-3, which carries REACH affected status.

For applications requiring the 520250-3, transition to the 5520250-3 eliminates obsolescence risk and aligns with current environmental and regulatory compliance standards. Both parts operate across the identical temperature range (-40°C to 85°C) and maintain equivalent performance ratings for Cat3 applications.

The tray packaging of the 5520250-3 supports efficient inventory management and component handling in production environments. No electrical or mechanical redesign is required when substituting the 5520250-3 for the 520250-3.

Frequently Asked Questions (FAQ)

Q: Are the 520250-3 and 5520250-3 electrically identical?

A: Yes. Both parts are 6p6c jack connectors with identical electrical specifications, including contact material (phosphor bronze), contact finish (gold at 50.0µin thickness), and Cat3 performance rating. They function identically in RJ11, RJ12, RJ14, and RJ25 applications.

Q: What is the primary reason to substitute the 520250-3 with the 5520250-3?

A: The 520250-3 is classified as obsolete, while the 5520250-3 is active. Additionally, the 5520250-3 is RoHS compliant and REACH unaffected, whereas the 520250-3 is RoHS non-compliant and REACH affected. These compliance differences make the 5520250-3 the preferred choice for current and future applications.

Q: Are the mechanical dimensions and mounting characteristics identical?

A: Yes. Both parts feature 90° right-angle orientation, through-hole solder termination, identical housing material (PBT and polyester), board lock and panel stops, and down-facing tab direction. No PCB layout modifications are required when substituting these parts.

Q: Does packaging differ between these parts?

A: Yes. The 520250-3 uses standard packaging, while the 5520250-3 is supplied in tray packaging. This difference does not affect electrical or mechanical performance and may provide advantages for automated assembly processes.

Q: What is the operating temperature range for both parts?

A: Both the 520250-3 and 5520250-3 operate across -40°C to 85°C. Thermal performance is identical between the two parts.

Q: Are there any compatibility concerns when substituting the 5520250-3 for the 520250-3?

A: No compatibility concerns exist. The parts are functionally equivalent across all electrical, mechanical, and thermal parameters. Direct substitution is valid for all applications.
