IEC 62474 DB
The IEC 62474 database (IEC 62474 DB) is the worldwide regulatory list of restricted substances, applications and thresholds as they apply to electronic products maintained by the IEC 62474 Validation Team committee. This list was the JIG-101 but was sunset in 2012 and became the IEC 62474 DB at that time.
TI products that are compliant to RoHS requirements are also fully compliant to the substances and thresholds defined in the IEC 62474 Database (was previously the Joint Industry Guide).
Data flags under the IEC 62474 DB field can be:
Yes: Fully compliant to IEC 62474 DB.
Affected: Compliant to IEC 62474 DB with the use of REACH SVHC substance(s) when contained above threshold, REACH SVHCs are not restricted from use but if contained above threshold, further information must be available.
No: Not compliant to IEC 62474 DB.
The European Union’s Registration Evaluation, Authorization and restriction of Chemicals (EU REACH) that lists the Substances of Very High Concern (SVHC) as well as substances under restriction, REACH Annex XVII. The REACH SVHC list is usually updated 2 times per year and the REACH Annex XVII list updated as needed. TI’s latest REACH statement is located on our Environmental information page.
Data flags under the REACH field can be:
Yes: Fully compliant to EU REACH.
Affected: Only used when a REACH SVHC substance(s) is contained above threshold 0.1% REACH Article threshold. Any REACH SVHC above the threshold is not restricted from use but if contained above threshold, further information must be available.
No: Not compliant to EU REACH – a restricted substance(s) under REACH Annex XVII is contained outside of allowed application.
Recyclable metals - ppm
The WEEE Directive (Waste Electrical and Electronic Equipment) has created interest in recyclable metals. TI reports values at the mass (mg) and ppm level. For WEEE, ppm calculations are at the component level. An example for calculating the ppm gold content follows.
Example: ppm= 1,000,000 * total amount of gold in component (mg) / total component weight (mg)
Gold mass = 0.23mg & Component mass = 128mg
1,000,0000 * 0.23 mg gold / 128mg component = 1,797 ppm
On January 27, 2003, the European Union passed the "Restriction on Use of Hazardous Substances in Electrical and Electronic Equipment," or "RoHS" legislation 2002/95/EC, which became effective July 1, 2006. TI’s latest RoHS statement is found on our Environmental information page. It restricted the following substances at the homogenous (material) level with associated maximum thresholds.
1. Lead (Pb): 0.1% (1000ppm)
2. Mercury (Hg): 0.1% (1000ppm)
3. Hexavalent Chromium (Cr6+): 0.1% (1000ppm)
4. Cadmium (Cd): 0.01% (100ppm)
5. Polybrominated biphenyls (PBB): 0.1% (1000ppm)
6. Polybrominated diphenyl ethers (PBDE): 0.1% (1000ppm)
Since then, there have been several updates to the Directive, the major ones being 2011/65/EU on 8 June 2011 that recasted exemptions expiring in 2011 to future dates (most in 2016). Amendment EU 2015/863 released on 4 June 2015 and comes into effect 22 July 2019 that added 4 phthalates to the list of 6 restricted substances:
7. Bis(2-ethylhexyl) phthalate (DEPH): 0.1% (1000ppm)
8. Butyl benzyl phthalate (BBP): 0.1% (1000ppm)
9. Dibutyl phthalate (DBP): 0.1% (1000ppm)
10. Diisobultyl phthalate (DIBP): 0.1% (1000ppm)
Further revisions continue to be released and TI will maintain its documentation and requirements as they are released, including information on exemptions that may be required.
Data flags under the RoHS field can be:
Yes: fully compliant to EU RoHS, no exemption required
Exempt: fully compliant to EU RoHS, with an exemption applied
No: Not compliant to EU RoHS
RoHS restricted substances – ppm calculation
The ppm calculations are at the homogeneous material level and are worst-case ppm for each RoHS substance.
PPM = (mass of substance / mass of material) * 1,000,000 * total amount of each RoHS substance contained in the material.
EXAMPLE: Lead (Pb) in leadframe example:
(mass of Lead: 0.006273 mg / total mass of leadframe: 62.730001mg) * 1,000,000 = 100 ppm
