NRC INFORMATION NOTICE NO. 91-01: SUPPLIER OF MISREPRESENTED RESISTORS

Addressees

All holders of operating licenses or construction permits for nuclear powler

reactors.

Purpose

This information notice is intended to notify addressees of the potential for

improperly marked and/or misrepresented resistors from Impala Electronics, an

electrical parts distributor located in Tampa, Florida. It is expected that

recipients of this notice will review the information for applicability to

their facilities and consider actions, as appropriate, to avoid similar problems.

However, suggestions contained in this information notice do not constitute NRC

requirements; therefore, no specific action or written response is required.

Discussion:

On September 25, 1990, and on November 15, 1990, the Government-Industry Data

Exchange Program (GIDEP) office issued Alert data sheets that discussed

concerns regarding the sale by an electrical parts distributor, Impala

Electronics, of improperly remarked Qualified Product List-(QPL) resistors and

non-QPL resistors that are misrepresented as QPL resistors. All remarked

resistors obtained from or through Impala were identified in the Alert to be

suspect. These resistors may be remarked witt incorrect information that may

include failure rate (FR) levels, tolerances, date codes, temperature

coefficient of resistance (TCR), etc.

In the Alert, the Defense Criminal Investigative Service recommended the

following actions for the disposition of all remarked products obtained

from or through this distributor:

a. All remarked products in stock should be returned to the original

manufacturer for replacement or credit, or

b. All products in stock should be screened to verify that the TCR and

tolerance are correct as marked, or that the parts are usable as is.

Because there are no known effective screens to verify the correctness

of marked date code or FR level, all parts used, or to be used in

applications in which proper date code or FR level are critical

should be removed and returned to the manufacturer.

Electronics, known for its responsiveness to requests for quick delivery of

resistors, was suspended from government contracting in December 1989, closed

its doors for business as of January 1990, and was indicted in August 1990.

This information notice requires no specific action or written response. If

you have any questions about the information in this notice, please contact the
