TE Connectivity 520250-2 Modular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 520250-2 is a modular jack connector designed for telecommunications and data applications. This component is a 6-position 4-conductor (6p4c) right-angle unshielded connector, commonly referenced as RJ11 or RJ14 format, suitable for Cat3 rated installations. The part features through-hole solder termination with board lock and panel stop functionality.

The 520250-2 carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement. Active substitute components maintain identical electrical and mechanical specifications while offering improved availability and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 520250-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must maintain identical specifications in the following categories:

Electrical Parameters:

• Connector type (Jack)
• Position and conductor count (6p4c)
• Category rating (Cat3)
• Contact material and finish specifications

Mechanical Parameters:

• Mounting configuration (Through Hole)
• Orientation (90° Right Angle)
• Termination method (Solder)
• Housing material composition
• Physical features (Board Lock, Panel Stops)

Environmental Parameters:

• Operating temperature range (-40°C to 85°C)
• Shielding classification (Unshielded)

The identified substitute maintains complete parameter alignment with the original component, differing only in product status classification and regulatory compliance certifications.

Engineering Selection Recommendations

The TE Connectivity 5520250-2 serves as the direct functional equivalent for the obsolete 520250-2 modular connector. Selection of the substitute component is based on the following engineering criteria:

Product Status Consideration: The original 520250-2 carries obsolete classification, indicating discontinued manufacturing and limited long-term availability. The 5520250-2 maintains active product status with confirmed inventory of 6,237 pieces, ensuring procurement reliability for current and future production requirements.

Regulatory Compliance: The substitute component achieves RoHS compliance, meeting current environmental and hazardous substance restrictions applicable to electronic components in regulated markets. The original component is classified as RoHS non-compliant. For applications subject to RoHS requirements, the 5520250-2 is the appropriate selection.

Functional Equivalence: All electrical and mechanical parameters remain identical between the original and substitute components. Pin configuration, contact specifications, mounting geometry, and environmental operating ranges are unchanged, ensuring direct interchangeability at the circuit board level.

Packaging Consideration: The substitute component is supplied in tray packaging, which may differ from the original packaging format. Verify packaging compatibility with existing assembly and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the 5520250-2 be used as a direct replacement for the 520250-2 in existing designs?

A: Yes. The 5520250-2 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, mounting configuration, orientation, termination method, contact materials, and operating temperature range. Direct substitution is supported at the component level.

Q: What is the primary reason for substituting the 520250-2?

A: The 520250-2 carries obsolete product status, indicating discontinued manufacturing. The 5520250-2 is an active product with substantially higher inventory availability (6,237 pieces versus 797 pieces), ensuring reliable procurement for ongoing production.

Q: Are there any compliance differences between the two components?

A: Yes. The 5520250-2 is RoHS compliant, while the 520250-2 is RoHS non-compliant. For applications subject to RoHS requirements or regulations in restricted markets, the 5520250-2 is the required selection. Both components share identical ECCN and HTSUS classifications.

Q: Does the packaging format affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The 5520250-2 is supplied in tray packaging. Verify that tray packaging is compatible with your assembly, storage, and handling procedures. Contact your procurement department if packaging format requires adjustment.

Q: Are the contact specifications identical between both components?

A: Yes. Both components feature phosphor bronze contacts with gold finish at 50.0µin (1.27µm) thickness. Contact material, finish type, and thickness specifications are identical.

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

A: Both the 520250-2 and 5520250-2 operate across the identical temperature range of -40°C to 85°C, supporting equivalent thermal performance in all applications.

Q: Can the 5520250-2 be used in Cat3 rated installations?

A: Yes. The 5520250-2 maintains Cat3 category rating identical to the original 520250-2, supporting equivalent performance in Cat3 telecommunications and data applications.
