TE Connectivity 5221014-1 SMB Coaxial Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5221014-1 is an SMB connector jack with male pin configuration, designed for 75 ohm RF applications. This right-angle through-hole solder connector operates at frequencies up to 4 GHz and is rated for 335 V with an operating temperature range of -65°C to 165°C. The part is currently active in production status with 734 units in stock.

Substitute parts are identified based on matching connector style, type, mounting configuration, and core electrical parameters. Alternative sources become necessary for supply chain continuity, design flexibility across manufacturers, or when specific impedance or material requirements align with application needs.

Substitute Part Grouping Explanation

Substitute parts are classified into two functional groups based on impedance specification:

Group 1: 75 Ohm Impedance (Direct Electrical Equivalents) Parts that maintain the 75 ohm impedance specification of the main part. These substitutes are electrically interchangeable for applications requiring 75 ohm characteristic impedance.

TE Connectivity 5415895-1
Samtec SMB7H-J-P-HN-RA-TH1

Group 2: 50 Ohm Impedance (Functional Alternatives) Parts that operate at 50 ohm impedance instead of 75 ohms. These are mechanically and functionally compatible SMB jack connectors with identical mounting and termination characteristics but different impedance specification. Selection of 50 ohm alternatives requires confirmation that the application circuit supports 50 ohm operation.

Engineering Selection Recommendations

For Direct 75 Ohm Replacement:

TE Connectivity 5415895-1 is the primary substitute for 5221014-1. Both parts are manufactured by TE Connectivity, maintain 75 ohm impedance, and carry identical electrical ratings. The primary difference is dielectric material (Polymethylpentene versus Polypropylene). Both parts are active in production status with RoHS compliance. Inventory availability is higher for 5415895-1 (1106 units versus 734 units).

Samtec SMB7H-J-P-HN-RA-TH1 is an alternative 75 ohm substitute with significantly higher inventory availability (92700 units). This part uses PTFE dielectric material and carries ROHS3 compliance. Insertion loss specification is not provided for this part.

For 50 Ohm Applications:

When circuit design supports 50 ohm impedance, the following active parts are available:

Amphenol RF 903-373J-51A offers the highest inventory level (1536 units) among 50 ohm alternatives. This part maintains all electrical ratings of the main part including 0.6 dB insertion loss and 335 V voltage rating. ROHS3 compliance is confirmed. Body finish is tin rather than nickel.

Cinch Connectivity Solutions 131-3701-306 and Radiall USA 2010-7511-000 are both active 50 ohm alternatives with PTFE dielectric material and ROHS3 compliance. Both support the full operating temperature range and snap-on fastening.

TE Connectivity 5228435-1 is not recommended for new designs due to obsolete product status, despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 5415895-1 be used as a direct replacement for 5221014-1?

A: Yes. Both parts are SMB jack connectors with 75 ohm impedance, identical mounting configuration (through hole, right angle), solder termination, and matching electrical ratings (335 V, -65°C to 165°C operating range). The dielectric material differs (Polymethylpentene versus Polypropylene), but both materials support the specified frequency range and operating conditions.

Q: What is the difference between 75 ohm and 50 ohm SMB connectors?

A: Impedance is a characteristic of the connector design that must match the transmission line impedance of the circuit. 75 ohm connectors are used in video and certain RF applications, while 50 ohm connectors are standard for RF and microwave applications. The connectors are mechanically identical but electrically incompatible if impedance mismatch is not acceptable in the application.

Q: Can I use a 50 ohm substitute in a 75 ohm circuit?

A: Impedance matching is determined by application requirements. Using a 50 ohm connector in a 75 ohm circuit creates an impedance discontinuity that may cause signal reflections and performance degradation. Substitution with different impedance requires circuit design confirmation.

Q: Why is TE Connectivity 5228435-1 listed as obsolete?

A: Product status is obsolete, indicating this part is no longer in active production. While inventory is currently available (900 units), new designs should not incorporate obsolete parts. Active alternatives are recommended for long-term supply chain stability.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. Parts marked as either RoHS Compliant or ROHS3 Compliant meet hazardous substance restrictions and are suitable for use in regulated applications.

Q: How do dielectric materials affect connector performance?

A: Dielectric materials (Polypropylene, Polymethylpentene, PTFE) determine electrical properties including insertion loss, frequency response, and temperature stability. All materials specified in these parts support the 4 GHz maximum frequency and -65°C to 165°C operating range. Material selection may affect specific performance characteristics not detailed in this reference.

Q: What is the significance of insertion loss specification?

A: Insertion loss (measured in dB) quantifies signal attenuation through the connector. Parts specifying 0.6 dB insertion loss provide measurable performance data. Parts without insertion loss specification do not provide this performance metric in available documentation.

Q: Are all substitute parts available in the same packaging?

A: The main part and most substitutes are supplied in bulk packaging. TE Connectivity 5228435-1 does not specify packaging information. Packaging requirements should be confirmed with supplier documentation for procurement purposes.
