Product/RoHS Directive Inquiries

Q1. Does Sharp still sell numerical display, light bar, and bar graph LEDs? Are these LEDs RoHS-compliant?
Q2. What is the difference between optoelectronics and regulators with suffixes of “0F” or “0H” and those without?
Q3. Have the model numbers for LED lamps and chip LEDs changed as a result of their becoming RoHS-compliant?
Q4. Is there a way to tell which products are RoHS-compliant and which aren't?
Q5. Two electronic components with different model numbers are listed as being the same component. Are they?
Q6. Even with photocouplers that have the same product numbers, there are some that have an underlined “4” and some that don't. What's the difference?
Q7. What does “OPIC output” signify?
 
Q1. Does Sharp still sell numerical display, light bar, and bar graph LEDs? Are these LEDs RoHS-compliant?
Production of numerical, light bar, and bar graph LEDs has ceased.
Such LED products were unable to receive RoHS certification due to their use of lead-containing elements. We thank you for your understanding.

Q2. What is the difference between optoelectronics and regulators with suffixes of “0F” or “0H” and those without?
Examples: GP1S52V has been changed to GP1S52VJ000F, PC357NT to PC357NTJ000F. When products are designated RoHS-compliant, their product numbers are changed to reflect that, by adding either “0F” or “0H.” However, certain products without “0F” or “0H” designation may still be RoHS-compliant (GP2S60 or PT100MC0MP for example).

Q3. Have the model numbers for LED lamps and chip LEDs changed as a result of their becoming RoHS-compliant?
Since the currently listed (in both the website and the catalog) LEDs and chip LEDs from Sharp were never targets of the RoHS directive, there has been no change to their product numbers.

Q4. Is there a way to tell which products are RoHS-compliant and which aren't?
• LSIs are indicated by underlined date codes in their product markings.
• Low power-loss voltage and chopper regulators are indicated by the presence of the letter “H” in their markings.
It is not possible to distinguish other types of products from their markings only.

Q5. Two electronic components with different model numbers are listed as being the same component. Are they?
Examples: GP1S52VJ000F and GP7S52VJ000F, GP1A05AJ000F and GP5A05AJ000F, PC817XJ0000F and PC817R6J000F, PC900V0NSZXF and PC900V0NSZX6. Certain identical items may have different product numbers depending on the factory that produced them. Parts like GP1S52VJ000F and GP1A05AJ000F are in fact interchangeable and may be substituted one for the other.

Q6. Even with photocouplers that have the same product numbers, there are some that have an underlined “4” and some that don't. What's the difference?
An underlined “4” indicates that the product has received VDE approval (example: DIN EN60747-5-2 : successor standard of DIN VDE0884).
Please refer to the datasheets and specification sheets for information on relevant models.

Q7. What does “OPIC output” signify?
“OPIC” (Optical IC) is a trademark of SHARP Corporation. An OPIC component consists of a light-detecting element and a signal-processing circuit integrated onto a single chip, making it possible to output directly to logic circuits like TTL or CMOS circuits.
