TE Connectivity 4-943213-1 Modular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-943213-1 is a modular jack connector with 4 positions in a vertical unshielded configuration. This component is classified as obsolete, indicating it is no longer in active production. The part features through-hole solder termination, phosphor bronze contacts with gold finish, and a polyester housing suitable for applications requiring board-guided, keyed modular connections.

Due to its obsolete status, sourcing this exact part number may present supply chain challenges. Equivalent and substitute parts are available to maintain design continuity and ensure project completion without extended lead times.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-943213-1 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector Type: SDL, Jack
• Number of Positions: 4 Positions
• Number of Ports: 1
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Contact Material: Phosphor Bronze
• Contact Finish: Gold, 50.0µin (1.27µm)
• Features: Board Guide, Keyed
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Orientation: Vertical to 90° Angle (Right)
• Shielding: Unshielded to Shielded
• Housing Material: Polyester to Liquid Crystal Polymer (LCP)
• Product Status: Obsolete to Active
• RoHS Compliance: Non-compliant to Compliant

The substitute part 4-1761207-1 maintains all core compatibility parameters while offering enhanced features including shielding and improved housing material. The orientation change from vertical to 90° angle represents a mechanical variation that affects board layout but does not compromise electrical functionality for 4-position modular jack applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 4-943213-1 is classified as obsolete, while the substitute part 4-1761207-1 maintains active production status. Active status ensures continued availability, shorter lead times, and ongoing manufacturer support.

Compliance and Certification: The substitute part 4-1761207-1 is ROHS3 compliant and REACH unaffected, providing superior regulatory alignment compared to the non-compliant main part. This compliance status is critical for applications subject to environmental and safety regulations in the European Union and other jurisdictions with equivalent requirements.

Electrical and Mechanical Compatibility: Both parts share identical contact material, finish specifications, and electrical characteristics. The core 4-position modular jack functionality is preserved. The orientation change from vertical to 90° angle requires board layout modification but does not affect electrical performance or contact integrity.

Housing Material Enhancement: The substitute part utilizes Liquid Crystal Polymer (LCP) housing instead of polyester, offering improved thermal stability and mechanical durability while maintaining the same moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the 4-1761207-1 directly replace the 4-943213-1 without any modifications?

A: Electrical substitution is valid. The 4-position modular jack configuration, contact materials, and termination method are identical. However, the orientation change from vertical to 90° angle requires printed circuit board layout modification. The connector footprint and mounting hole positions differ due to the right-angle configuration.

Q: What are the key differences between these two parts?

A: The primary differences are orientation (vertical versus 90° right angle), shielding (unshielded versus shielded), housing material (polyester versus LCP), and product status (obsolete versus active). All other electrical and mechanical specifications remain consistent.

Q: Is the shielded version compatible with unshielded applications?

A: Yes. A shielded connector can be used in applications originally designed for unshielded connectors. The shielding provides additional electromagnetic interference protection without compromising backward compatibility. The 4-position contact configuration and solder termination remain unchanged.

Q: Does the housing material change affect performance?

A: The Liquid Crystal Polymer housing in the substitute part provides enhanced thermal and mechanical properties compared to polyester. Both materials maintain the same moisture sensitivity level and are suitable for the specified operating temperature range. The LCP housing offers improved durability and dimensional stability.

Q: Are there any compliance advantages to using the substitute part?

A: Yes. The 4-1761207-1 is ROHS3 compliant and REACH unaffected, whereas the original part is RoHS non-compliant with undefined REACH status. For applications subject to environmental regulations, the substitute part provides superior compliance alignment.

Q: What is the packaging difference?

A: The main part 4-943213-1 has undefined packaging, while the substitute part 4-1761207-1 is supplied in tray packaging. Tray packaging is standard for production environments and facilitates automated assembly processes.

Q: Can I use the 4-943213-1 if I can still source it?

A: The 4-943213-1 remains electrically and mechanically valid for its original application. However, its obsolete status presents supply chain risk. The active status of the 4-1761207-1 ensures long-term availability and reduces procurement uncertainty.
