KE1877-ND

My customer needs other diameter of this part KE1877-ND.
KE1877-ND is 0,38 mm but they also needs with 0,3 mm and 0,5 mm. What is the part number for these?

Hello @kathrine

for the 0.5mm diameter we have part number KE1871-ND

I did not find solder wire that is RMA and the same composition as part number KE1877-ND in the 0.3 mm diameter

Hi kathrine,

The KE1877-ND (Kester part number 24-6337-9727) is part of the Kester “285” series lead-containing solder with RMA type flux.. It does not appear that Kester makes a “285” series solder in 0.30mm diameter. This would equate to approximately 28.6 AWG.

The only lead-containing wire solder we carry in approximately that diameter is the T0051403399 (specifically, it’s 0.31mm diameter), but it uses a no-clean type flux rather than RMA flux, and has a 60/40 ratio of tin to lead rather than the 63/37 ratio of the KE1877-ND.

The next smaller size that Kester makes in the “285” series is the 30 AWG, 0.25mm diameter KE1878-ND (Kester part number 24-6337-9744). This is your only option if you need “285” type solder in a diameter smaller than the KE1877-ND.
