TE Connectivity 226990-7 BNC Connector Jack Equivalent & Substitute Parts

Part Overview

The TE Connectivity 226990-7 is a BNC connector jack (female socket) rated for 50 ohms impedance, designed for panel mount through-hole applications with right-angle solder termination. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and design applications. The connector features bayonet lock fastening, operates across -55°C to 85°C, and supports frequencies up to 4 GHz with a 500 V voltage rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 226990-7 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain constant for direct substitution:

• Connector style (BNC)
• Connector type (Jack, Female Socket)
• Impedance (50 Ohms)
• Mounting configuration (Panel Mount, Through Hole, Right Angle)
• Termination method (Solder for both contact and shield)
• Fastening mechanism (Bayonet Lock)
• Frequency rating (4 GHz maximum)
• Operating temperature range (-55°C ~ 85°C)
• Voltage rating (500 V)
• Mating cycle rating (500)
• Dielectric material (Polymethylpentene)
• Center contact material (Phosphor Bronze)

Substitute parts are grouped into two categories based on center contact plating and packaging configuration:

Tin-Plated Center Contact (226990-1, 5226990-1): These parts maintain identical center contact plating to the original 226990-7 and differ only in packaging format and product status.

Gold-Plated Center Contact (226990-3, 5226990-3): These parts feature gold plating on the center contact instead of tin, providing enhanced corrosion resistance while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 226990-1

The 226990-1 is the direct functional equivalent to the obsolete 226990-7, maintaining identical center contact plating (tin) and all electrical and mechanical specifications. This part carries active product status and ROHS3 compliance certification, making it suitable for new designs and ongoing production. The tube packaging format aligns with standard component procurement practices.

Secondary Recommendation: 5226990-1

The 5226990-1 provides equivalent electrical and mechanical performance to 226990-7 with ROHS3 compliance and active product status. This part differs in packaging (bulk format) and does not include the connector accessories (lockwasher and nut). Selection of this part requires verification that mounting hardware is sourced separately.

Alternative with Enhanced Corrosion Resistance: 226990-3 or 5226990-3

The 226990-3 and 5226990-3 offer gold-plated center contacts, providing superior corrosion resistance compared to the tin-plated original. Both parts maintain active product status and all critical electrical and mechanical parameters. The 226990-3 is supplied in bulk packaging, while 5226990-3 is also bulk packaged. These parts are suitable for applications requiring extended service life in corrosive environments or high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can 226990-1 be used as a direct replacement for 226990-7?

A: Yes. The 226990-1 maintains identical electrical specifications (50 ohms, 4 GHz, 500 V), mechanical configuration (panel mount, through-hole, right-angle, bayonet lock), and termination method (solder). The primary difference is product status (active versus obsolete) and RoHS compliance certification.

Q: What is the difference between tin-plated and gold-plated center contacts?

A: The center contact plating material does not alter electrical performance within the specified parameters. Gold plating provides enhanced resistance to oxidation and corrosion compared to tin plating, extending component service life in corrosive environments or applications with extended storage periods.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (tube versus bulk) is a procurement and logistics consideration only. Electrical and mechanical specifications remain identical regardless of packaging configuration.

Q: Are the included accessories (lockwasher and nut) essential for operation?

A: The lockwasher and nut are mechanical fastening components for panel mount installation. Parts 226990-1 and 226990-3 include these accessories. Parts 5226990-1 and 5226990-3 do not include accessories and require separate procurement of mounting hardware.

Q: Which substitute part should be selected for new product designs?

A: For new designs, 226990-1 is recommended due to active product status, ROHS3 compliance, and inclusion of mounting accessories. If gold-plated center contacts are required for enhanced corrosion resistance, 226990-3 is the equivalent alternative.

Q: Are all substitute parts RoHS compliant?

A: Parts 226990-1, 5226990-1, and 5226990-3 carry ROHS3 compliance certification. Part 226990-3 is marked as "Not applicable" for RoHS status. The original 226990-7 is RoHS non-compliant.

Q: Can substitute parts be intermixed in the same assembly?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications, allowing intermixing within the same assembly without performance degradation. However, mixing tin-plated and gold-plated variants may introduce inconsistent corrosion resistance characteristics across the assembly.
