Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 31-335-RFX is a direct electrical and mechanical equivalent to the 112182. Both parts are manufactured by Amphenol RF and share identical electrical specifications, mechanical construction, and material composition.

Product Status Consideration: The 112182 carries a "Not For New Designs" designation, while the 31-335-RFX maintains "Active" product status. For applications requiring long-term component availability and manufacturer support, the 31-335-RFX is the appropriate selection.

Compliance and Certification: Both parts are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Both are REACH affected and classified under ECCN EAR99. No compliance differential exists between the two parts.

Packaging Difference: The 112182 is supplied in bag packaging, while the 31-335-RFX is supplied in bulk packaging. This distinction affects inventory management and procurement processes but does not alter electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 31-335-RFX be used as a direct replacement for the 112182?

A: Yes. The 31-335-RFX meets all electrical and mechanical specifications of the 112182. Both parts are 50-ohm BNC male plug connectors with right-angle crimp termination, identical frequency ratings, voltage ratings, and cable compatibility.

Q: What is the significance of the "Not For New Designs" status on the 112182?

A: This designation indicates the part has been superseded in the manufacturer's product line. While existing inventory may remain available, Amphenol RF recommends using the active equivalent (31-335-RFX) for new applications to ensure continued availability and manufacturer support.

Q: Are there any performance differences between the two parts?

A: No. Both parts exhibit identical insertion loss (0.2 dB), frequency response (4 GHz maximum), voltage rating (500 V), and mating cycle rating (500 cycles). Material composition, plating, and dielectric properties are identical.

Q: Does the packaging difference affect compatibility?

A: No. The packaging difference (bag versus bulk) is a supply and logistics consideration only. It does not affect the electrical or mechanical performance of the connector itself.

Q: Are both parts suitable for RG-58 cable applications?

A: Yes. Both the 112182 and 31-335-RFX are compatible with RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cable types.

Q: What is the operating temperature range for these connectors?

A: The 31-335-RFX is rated for -65°C to 165°C operation. Operating temperature data for the 112182 was not provided in the specification parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both the 112182 and 31-335-RFX are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).
