Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-1478955-0 is determined by strict alignment of core electrical and mechanical parameters. The substitute part Amphenol RF 132198 shares the following critical parameters: SMA connector style, Jack Female Socket type, 50 Ohm impedance, solder contact termination, crimp shield termination, beryllium copper center contact material, PTFE dielectric material, identical operating temperature range (-65°C ~ 165°C), 500 mating cycles, and equivalent RoHS compliance status.

The primary distinction between these parts is the mounting configuration. The main part (1-1478955-0) is configured for panel mount with bulkhead front side nut fastening, while the substitute (132198) is designed for free hanging in-line mounting. This difference affects system integration but does not alter the core RF performance characteristics or electrical specifications. Both parts support threaded fastening and are suitable for the same cable groups with minor variations in supported cable specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1-1478955-0 and Amphenol RF 132198 are active products with current manufacturing status and full RoHS compliance certification. The TE Connectivity part maintains RoHS Compliant status, while the Amphenol RF substitute achieves ROHS3 Compliant status, indicating compliance with the most current RoHS directive requirements.

Selection between these parts depends on system mounting architecture. The TE Connectivity 1-1478955-0 is specified for panel mount applications requiring bulkhead installation with front side nut fastening. The Amphenol RF 132198 is configured for free hanging in-line cable applications without panel mounting requirements.

Frequency capability differs between the parts. The TE Connectivity part supports operation to 18 GHz, while the Amphenol RF substitute operates to 12.4 GHz. Applications requiring frequencies above 12.4 GHz require the TE Connectivity part. For applications operating at or below 12.4 GHz, both parts are electrically equivalent.

The Amphenol RF 132198 provides higher voltage rating (375 V versus 250 V), which may be advantageous in high-voltage RF applications. Both parts share identical operating temperature range, mating cycle rating, center contact material, and dielectric material specifications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 132198 directly replace the TE Connectivity 1-1478955-0 in all applications?

A: Direct replacement is limited by mounting type and frequency requirements. The Amphenol RF part is designed for free hanging in-line mounting, while the TE Connectivity part requires panel mount bulkhead installation.
