BDFHYK Alternator 23100-ZW40A
Product description
Key points
If you’re replacing an alternator, matching the vehicle application and electrical details matters more than choosing a part with a long feature list.
The BDFHYK is listed for specific Nissan models and engine sizes, with a 12V, 100A output. Its OE reference numbers give you another way to compare it with the part being replaced.
It suits you if your vehicle matches one of the listed applications and the alternator’s specifications line up. This is a targeted replacement, not a universal fit.
The listed applications are the Nissan Sentra with a 2.0L I4 for 2011–2012, Nissan Versa with a 1.8L I4 for 2009–2012, and Nissan NV200 with a 2.0L I4 for 2015. The unit has clockwise rotation, an IR/IF regulator and fan designation, plug code 319, and an SC6 pulley class described as a six-groove pulley. OE references include 23100-ZW40A, 23100ZW40B, and A002TG1581.
How to use it
This is an alternator replacement part, so the useful first step is to identify the unit currently in the vehicle and compare its OE number and configuration with the details here. Matching only the model name can be risky: year, engine, connector, rotation, and pulley details all matter for fitment.
Keep in mind that the compatibility information is limited to the model years and engine sizes listed above, it doesn’t establish fitment for other Nissan versions. If the original alternator’s label is still readable, compare its part number against the supplied OE references rather than relying on a general model match alone.
Practical tips
Picture checking the old unit before arranging a replacement: note its label, inspect the plug shape, and count the pulley grooves. Then compare those details with the BDFHYK’s references, plug code 319, and SC6 pulley class. The listing also specifies 12V, 100A, and clockwise rotation, which can help distinguish this unit from an alternator that looks similar but has different specifications.
A buyer prioritizing a broad, flexible fitment range may prefer a part explicitly listed for more vehicle variants. This one makes more sense when the vehicle and replacement details match closely. You may want to skip it if your year, engine, or OE reference falls outside the information provided, the listing does not establish compatibility beyond its stated applications.
Practical doubts
Which vehicles are listed as compatible? The Nissan Sentra 2.0L I4 for 2011–2012, Versa 1.8L I4 for 2009–2012, and NV200 2.0L I4 for 2015.
What are its electrical specifications? The listing gives a 12V rating and 100A output, with clockwise rotation.
Which OE numbers can I compare? Listed references include 23100-ZW40A, 23100ZW40B, 23100-ZW40B, and A002TG1581, among others. Use the full reference list to compare with your existing part.
Is it worth it?
The BDFHYK is worth considering when you need a replacement for one of the exact Nissan applications listed and can confirm the OE reference and pulley configuration. Its stated electrical ratings and identifying details make it easier to compare against the part coming out of the vehicle. If your vehicle information is incomplete or does not match, this listing alone isn’t enough to confirm fitment, so choosing a part with verified application details for your exact vehicle is the safer route.
