Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 226990-3 are classified into two categories based on parametric alignment:

Direct Manufacturer Equivalents (TE Connectivity): Parts 5226990-3 and 5226990-1 maintain identical core electrical and mechanical specifications including 50-ohm impedance, 4 GHz maximum frequency, 500 V voltage rating, -55°C to 85°C operating temperature range, 500 mating cycles, and bayonet lock fastening. These parts share the same BNC jack female socket configuration with right-angle panel mount through-hole solder termination. The primary difference between 5226990-3 and 5226990-1 is center contact plating material (gold versus tin). Both are RoHS3 compliant.

Similar Cross-Manufacturer Alternatives (Amphenol RF): Parts 031-5431-1010 and 031-5538-1010 provide functional equivalence with the following constraints: maximum frequency is limited to 1 GHz (versus 4 GHz for the main part), dielectric material differs (polypropylene versus polymethylpentene), and insertion loss is specified at 0.2 dB. These Amphenol RF connectors maintain 50-ohm impedance, 500 V voltage rating, -55°C to 85°C operating temperature, 500 mating cycles, and identical mounting configuration. Both include board lock feature and are RoHS3 compliant.

Engineering Selection Recommendations

For applications requiring 4 GHz maximum frequency operation: Select TE Connectivity parts 226990-3, 5226990-3, or 5226990-1. These three parts maintain full frequency capability and are electrically equivalent. Part 5226990-3 is recommended for new designs due to RoHS3 compliance certification. Part 5226990-1 provides an alternative with tin center contact plating and equivalent RoHS3 compliance status.

For applications with frequency requirements limited to 1 GHz or below: Amphenol RF parts 031-5431-1010 and 031-5538-1010 are functionally suitable. These parts are RoHS3 compliant and provide equivalent 50-ohm impedance, voltage rating, and operating temperature range. Part 031-5538-1010 is supplied in tray packaging, while 031-5431-1010 is supplied in bulk packaging.

For legacy system compatibility: The original TE Connectivity 226990-3 remains the primary specification. Direct substitution with 5226990-3 or 5226990-1 is supported without design modification due to identical mechanical and electrical parameters within the TE Connectivity product line.

For compliance-driven applications: Parts 5226990-3, 5226990-1, 031-5431-1010, and 031-5538-1010 all carry RoHS3 compliance certification. The original 226990-3 is marked as not applicable for RoHS status.

Frequently Asked Questions (FAQ)

Q: Can 031-5431-1010 or 031-5538-1010 be used as direct replacements for 226990-3 in all applications?

A: These Amphenol RF parts are functionally equivalent for applications operating at 1 GHz or below. Applications requiring operation above 1 GHz must use TE Connectivity parts 226990-3, 5226990-3, or 5226990-1, which are rated to 4 GHz. All other electrical and mechanical parameters are compatible.

Q: What is the difference between 5226990-3 and 5226990-1?

A: Both parts are TE Connectivity equivalents with identical specifications except for center contact plating. Part 5226990-3 uses gold plating, while 5226990-1 uses tin plating. Both are RoHS3 compliant and rated to 4 GHz.

Q: Does packaging type affect electrical performance?

A: No. Part 031-5538-1010 is supplied in tray packaging while 031-5431-1010 is supplied in bulk packaging. Electrical and mechanical performance are identical. Packaging selection is based on handling, storage, and assembly process requirements.

Q: Are the dielectric material differences between TE Connectivity and Amphenol RF parts significant?

A: TE Connectivity parts use polymethylpentene (PMP) dielectric, while Amphenol RF parts use polypropylene (PP) dielectric. Both materials support the specified operating temperature range of -55°C to 85°C and 500 V voltage rating. Material selection affects frequency response characteristics; TE Connectivity parts support 4 GHz while Amphenol RF parts are rated to 1 GHz.

Q: Can the original 226990-3 be used interchangeably with 5226990-3 in new designs?

A: Yes. Both parts are mechanically and electrically identical. Part 5226990-3 is recommended for new designs due to RoHS3 compliance certification, while 226990-3 is marked as not applicable for RoHS status.

Q: What is the significance of the board lock feature on Amphenol RF parts?

A: The board lock feature on 031-5431-1010 and 031-5538-1010 provides additional mechanical retention on the PCB. This is a supplementary feature not present on TE Connectivity parts. The feature does not affect electrical compatibility or core mechanical mounting characteristics.
