How Altera's RoHS-Compliant Options are Used and Identified

Altera offers many products in leaded and RoHS-compliant options. Figure 1 shows where the lead (Pb) is present in the leaded devices.

Altera’s RoHS-compliant option replaces the lead (Pb) with the most trusted industry-standard lead alternatives to help ease the transition to RoHS-compliant devices.

Table 1 specifies the RoHS-compliant alternative substances used for different Altera® packages as well as the backwards-compatibility of the manufacturing flow.

  1. External solder ball only. Internal solder bumps in the flip-chip packages will remain unchanged.
  2. The RoHS-compliant alternative materials used in BGA and FineLine BGA (FBGA) packages have a higher melting point than the leaded materials and, therefore, require a different manufacturing flow to mount the devices on a PCB board.

Identifying Altera’s RoHS-Compliant Devices

Identification of RoHS-compliant products is one of the remaining major concerns for RoHS-compliant conversion. Altera recognizes this issue and uses the following mechanisms to identify and distinguish RoHS-compliant components from leaded components.

Ordering Codes: All RoHS-compliant components are denoted by an "N" suffix at the end of the part number. For example, "EP1C12F324C6N."

Device Marking: All RoHS-compliant components are marked with the ordering codes that contain the “N” suffix.

Device Marking and Box Label: All Altera RoHS-compliant device packages with a body size of 17 x 17 mm and greater are marked with eN category codes in accordance with JEDEC standard JESD-97 (PDF). The moisture barrier bag and the shipping box are also marked with information to help identify RoHS-compliant components. Additional information including a sample label is available in ADV0501 (PDF).
