Fitment FAQ

Will this part fit my specific model and year?

This voltage regulator rectifier is intended for Honda; CBR600 F4i; 2001–2006; CBR900RR / 929RR; 2000–2002. It is best matched to original part number(s) 31600-MCJ-641, 31600-MCJ-640, 31600-MCZ-003, 31600-MEE-003. Key physical/spec details from the product data include Voltage: 12V DC, 12V. Use the compatibility table and product photos together before ordering.

Do I need to match the OEM part number?

Yes. Match your original part number to 31600-MCJ-641, 31600-MCJ-640, 31600-MCZ-003, 31600-MEE-003 before purchase. For this voltage regulator rectifier, also compare the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. This is especially important for Honda MCJ-641/CBR600 models because similar model names can use different parts by year or trim.

What models or situations does this part not fit?

Do not order this voltage regulator rectifier for machines outside the listed compatibility, or for units with different pin counts, plug shapes, AC/DC system types, or mounting-hole spacing. If your original part number does not cross-reference with 31600-MCJ-641, 31600-MCJ-640, 31600-MCZ-003, 31600-MEE-003, treat the fitment as unconfirmed. Model years outside 2001–2006, 2000–2002, 2002–2003, 2001, 2006 should be verified separately. Do not rely only on the model name or engine size.

What should I check before ordering?

Before ordering, compare your original part with the photos and check the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. Confirm OEM/cross-reference number(s): 31600-MCJ-641, 31600-MCJ-640, 31600-MCZ-003, 31600-MEE-003. Recheck listed specs such as Voltage: 12V DC, 12V. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
