[sdiy] Vactrol/Optocoupler/LDR part numbers (Was: Eu might bebanning Vactrols and LDRs??)

[Jerry Gray-Eskue]

FYI H11F1

http://www.mouser.com/Search/Refine.aspx?Keyword=H11F1

Mouser is showing the H11F1 as RoHS compliant. Apparently the levels are a
low enough percentage to qualify as RoHS.

RoHS Compliant
Environmental Laws restrict the use of certain hazardous substances. "RoHS:
Compliant" addresses the laws transposed from the European Union directive
2002/95/EC known as the RoHS Directive.

The RoHS Compliance of any product so designated is based upon evidence from
the producer (manufacturer) that the part number is in compliance with the
RoHS Directive. Mouser Electronics has taken all reasonable steps to confirm
producers' statements and other evidence regarding the absence of the
restricted substances to support the manufacturers' claim of compliance.

For reference, in compliance with RoHS (EU Directive 2002/95/EC) the maximum
concentration values of the restricted substances by weight in any
homogenous materials are:
. Cadmium/Cadmium Compounds 0.01%
. Hexavalent Chromium/ Hexavalent Chromium Compounds 0.10%
. Lead/Lead Compounds 0.10%
. Mercury/Mercury Compounds 0.10%
. Polybrominated Biphenyls (PBBs) 0.10%
. Polybrominated Diphenylethers (PBDEs)0.10%
   - Including Decabromodiphenyl Ether (Deca-BDE) 0.10%
Date: 9/9/2009
Mouser Part #: 512-H11F1M
Mfr.'s Part #: H11F1M
Mfr.: Fairchild Semiconductor
Description: ANALOG FET

This information is valid when RoHS Compliance is indicated on your packing
list from Mouser Electronics, Inc.

>So can someone give me a quick 101 on availible parts, and what the most
usefull ones are?

Julian,

As far as ready-made optocoupler/LDRs go...

The one I used to use regularly is the H11F3 by Fairchild. The last time I
looked there was stock in the US at decent prices - but I haven't seen it
available in the UK for many months.

There is also a H11F1 and 2 - I think it's only the maximum resistance that
changes (1MOhm, 2MOhm, 3MOhm - if I remember correctly.)

A company called Vactec do/used to do a VTLC5CX that's pretty highly
regarded - again, not seen it in the UK for ages.

Pity.

HTH,

Justin
