Minco Part Numbers Decoded

By Minco Staff

Porsche cars have a unique system of model numbering. The high-performance, rear-engine 911 was followed by the economy, mid-engine 914 co-developed with Volkswagen. A few years later, Porsche introduced the front-engine, eight cylinder 928 luxury tourer. The numbering system makes no apparent sense. Actually, a Porsche model number is taken from the blueprint number of the model’s original drawing and follows that model through its entire life. That’s why entirely unrelated Porsche models could, in theory, have consecutive model numbers. All Porsche model numbers tell you is the order in which the various models were conceived.

Minco’s standard RTD/sensor part numbers are much more informative. For example, a code reading S331PA3T120AC1 indicates:

  • An embedment type resistance temperature sensor (base model number S331)
  • It has a 100-ohm platinum sensing element with a .00392 TCR (PA)
  • It has three leads (3)
  • It has TFE lead insulation (T)
  • Its lead length is 120” (120)
  • It includes a retaining ring and spring for mounting in a hole (AC1) 

The same base model is available in a variety of configurations. Each can be specified by changing characters in the model number. For example, if the “3” following PA were changed to “4”, it would specify four leads instead of three.  If the “T” were changed to “S”, it would change the lead insulation from plain TFE to TFE with stainless steel braid.

Obviously, the information embedded in the part number is useful within Minco to ensure that customers are getting the part they want in the correct configuration. But there are also benefits to the customer in understanding the numbering system. First, it speeds up ordering. But equally important, it gives you a list of options to consider in specifying parts. Moreover, an understanding of the model numbering system allows part configurations to be identified during later repair/refurbishment activities.

A product number this long is a lot for a customer to remember, especially since some of those characters can change depending on the part’s configuration. The good news is that the list of common options for each base model can be found in a table on the part’s Minco catalog page. The process of specifying a part number is simple. Starting at Minco Components, find the catalog page for your desired part, find the table listing available options and plug in the characters that match your desired configuration. Being able to configure your own parts by number simplifies things for both your technical staff and your purchasing people. Of course, if you need one-on-one help to identify and order parts, we’re here to answer your questions and make sure you are getting the best fit for your application.
