Is there an alternative to H2102B01 for the same board thickness?

You can see our full range of terminal pins in this section of the catalog. One of our technical engineers will also be in touch to help you identify the closest match to your requirements.



What is the recommended material thickness for clip S0991-46R?

The recommended material thickness for use with the S0991-46R clip is 0.20 to 0.25mm thick - that's 0.008 to 0.010 inch thickness. We use 0.2mm thick as one of our standard material thicknesses for shield cans, but it may also be possible to locate 0.25mm material thickness shield cans. If you need to use a different material thickness to these, you'll need to use a different SMT clip.


Merrimack, NH, USA

For M80-4861005A can we use the M80-0190005 contacts in place of supplied contacts?

Yes you can. Crimp contacts M80-01100xx, M80-01300xx and M80-01900xx all fit in the same housings, and are therefore interchangeable. You can even mix them within the same housing if you wish. Just make sure you use the right crimp tool setting for each contact.

Neu-Anspach, Germany

Why is there no voltage rating for single contacts, like S7091-42R or S7081-42R?

Voltage rating is calculated from the flashover voltage - the voltage at which the electricity can break down the air gap and jump between two contacts. With a single contact, the voltage rating you achieve will depend on the space you leave between two contacts, or a contact and any other conducting element. So we are unable to give a voltage rating for single contacts.


Gdynia, Poland

Are the G125-2042696L0 connectors sold together with female crimp contacts?

The G125-2042696L0 is just the crimp housing, it does not include the contacts. As you can see on the product page, there is a choice of loose crimp contacts (G125-0010005 for 26 AWG, G125-0020005 for 28-32 AWG) and pre-wired crimp contacts (G125-FW series) that you can purchase separately.


Dallas, TX, USA

We do not have any specific recommendations on cable type - this range is based on the same physical dimensions and specifications as MIL-DTL-5015, so any cable compatible with this standard will work for these connectors.


Salisbury, MD, USA

What is the manual crimp tool for the M40-1000046?

Sorry, but there is no manual crimp tool for the M40-1000046, it is just too small a crimp. We can supply pre-cabled contacts (the M40-9 series), or you can ask us to quote for a complete cable assembly. Otherwise, you would need to contact a crimp machine supplier and commission crimp tooling for an automatic or semi-automatic machine.

Are connectors M80-8630442 & M80-8890405 tested for vibration / shock / bump / acceleration as mated items?

M80-863 is a friction latch Datamate L-Tek, we only recommend locking latches for vibration. Please use M80-8530442 instead. We test male PCB to female PCB, as the weight of an attached cable would heavily influence the results, and cause wide variation. You'll need to do your own testing for your specific cable layout.

I need to know the difference between a British Standard PN and the Harwin commercial PN call out. I know they are the same but what makes a BS number BS?

Commercial & British Standard (BS) Datamate are manufactured on the same line. But BS product is 100% inspected, product from every batch is tested, & yearly tests are also carried out; to meet the requirements of BS9525 F0033. BS Datamate are generally specified only in safety-critical applications, as it carries a price premium.
