Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 226993-1 is determined by strict equivalence across the following critical parameters: connector style (BNC), connector type (jack/female socket), impedance (50 ohms), mounting configuration (panel mount through-hole), contact and shield termination method (solder), fastening mechanism (bayonet lock), operating temperature range (-55°C ~ 85°C), voltage rating (500 V), and mating cycle rating (500 cycles).

Parts are classified into two substitution categories:

Direct Equivalent: Parts that match all critical electrical and mechanical parameters without deviation. These parts are functionally interchangeable in the same application context.

Similar Equivalent: Parts that satisfy all critical electrical and mechanical parameters but may differ in secondary characteristics such as frequency maximum rating, dielectric material, center contact plating, body material specification, or housing color. These parts are electrically and mechanically compatible but require engineering review for application-specific frequency or environmental constraints.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5226993-1 (Direct Equivalent): This part is the direct equivalent to the 226993-1, matching all critical electrical and mechanical parameters including impedance, frequency rating (4 GHz), operating temperature, voltage rating, and mating cycle specification. The 5226993-1 is supplied in tube packaging and carries ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the main part. Selection of the 5226993-1 is appropriate for applications requiring RoHS3 compliance or when tube packaging is preferred for automated assembly processes.

Amphenol RF 031-5539 (Similar Equivalent): This part satisfies all critical electrical and mechanical parameters for BNC 50-ohm panel mount through-hole solder termination. The 031-5539 differs from the main part in maximum frequency rating (1 GHz versus 4 GHz), dielectric material (polypropylene versus polymethylpentene), center contact plating (gold versus tin), and includes a board guide feature. The 031-5539 is ROHS3 compliant and REACH affected. Selection of the 031-5539 is appropriate for applications operating at frequencies up to 1 GHz where the lower frequency specification is acceptable and where the board guide feature provides mechanical benefit. Applications requiring operation above 1 GHz must use the 226993-1 or 5226993-1.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5226993-1 be used as a direct replacement for the 226993-1?

A: Yes. The 5226993-1 is a direct equivalent with identical electrical and mechanical specifications. Both parts are BNC jack connectors rated for 50 ohms, 4 GHz maximum frequency, panel mount through-hole solder termination, and 500 V operation. The primary differences are packaging format (tube versus unspecified) and regulatory compliance status (ROHS3 compliant versus non-compliant).

Q: What is the frequency limitation of the Amphenol RF 031-5539 compared to the TE Connectivity 226993-1?

A: The 031-5539 is rated for a maximum frequency of 1 GHz, while the 226993-1 is rated for 4 GHz. Both parts are mechanically and electrically compatible for 50-ohm BNC applications. The 031-5539 is suitable for applications operating at frequencies up to 1 GHz. Applications requiring operation above 1 GHz must use the 226993-1 or 5226993-1.

Q: Are there differences in dielectric material between these parts?

A: Yes. The 226993-1 and 5226993-1 use polymethylpentene (PMP) dielectric material, while the 031-5539 uses polypropylene (PP). Both materials are suitable for RF applications within their specified frequency ranges. The PMP dielectric in the TE Connectivity parts supports the higher 4 GHz frequency rating.

Q: What is the significance of the board guide feature on the 031-5539?

A: The board guide feature on the 031-5539 provides mechanical alignment and support during PCB assembly and mating operations. This feature is not present on the 226993-1 or 5226993-1. The board guide may provide assembly benefits in high-volume manufacturing environments but is not required for electrical or mechanical compatibility.

Q: Does center contact plating affect substitution compatibility?

A: Center contact plating (tin on the 226993-1 and 5226993-1 versus gold on the 031-5539) does not affect electrical or mechanical compatibility for the specified operating parameters. Both plating materials are suitable for solder termination and 500-cycle mating life. Gold plating on the 031-5539 may provide enhanced corrosion resistance in certain environmental conditions.

Q: What packaging options are available for these parts?

A: The 226993-1 packaging is not specified in the provided data. The 5226993-1 is supplied in tube packaging, suitable for automated assembly processes. The 031-5539 is supplied in bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are all three parts RoHS compliant?

A: No. The 226993-1 is RoHS non-compliant. The 5226993-1 and 031-5539 are both ROHS3 compliant. For applications requiring RoHS compliance, the 5226993-1 or 031-5539 must be selected.

Q: What is the REACH status difference between these parts?

A: The 226993-1 has vendor-undefined REACH status. The 5226993-1 is REACH unaffected, indicating no REACH-regulated substances are present. The 031-5539 is REACH affected, indicating the presence of REACH-regulated substances. For applications in REACH-regulated markets, the 5226993-1 is the preferred choice.
