What is the recommended PCB hole size for the PH through-hole headers for harder resin boards?

The following are the recommended drill hole sizes for the most common PCB materials:

JST Part Numbers

B*B-PH-K-S  (LF)(SN)
S*B-PH-K-S  (LF)(SN)

Replace "*" with the applicable number of circuits (2 ~ 16).

Recommend PCB hole size (all dimensions are in mm):

Paper-based epoxy resin

Ø0.70 ~ 0.75 for 2 circuits
Ø0.75 ~ 0.80 for 3 ~ 16 circuits

Glass-based epoxy resin (without through-hole)

Ø0.70 ~ 0.75 for 2 circuits
Ø0.75 ~ 0.80 for 3 ~ 16 circuits

Note: Hole size of the paper-based epoxy PC board and glass-based epoxy resin PC board
(without through hole) is the value set for the drill hole (NC processing).

Glass-based epoxy resin (with through-hole)

Ø0.80 ~ 0.85 for 2 circuits
Ø0.85 ~ 0.90 for 3 ~ 16 circuits

Note: Hole size of glass-based epoxy PC board (with through-hole) is the finished dimension
after plating through-hole.

Is there a 22AWG contact for the PH series?

Yes. There is a contact for the PH series that will work for 22AWG wire. The part number is SPH-001T-P0.5S. It has an AWG range of 26 to 22 with an insulation outer diameter range of 0.9 to 1.5mm. For 26 and 24 AWG, JST suggests using UL1007 wire. For 22AWG, we suggest UL1061 or UL1571.

Header part number difference

What is the difference between B( )B-PH-K-S and B( )B-PH-KL? [replace ( ) with the applicable number of circuits]

B( )B-PH-K-S is the standard, through-hole header in a natural white color. B( )B-PH-KL is a low insertion force type header in gray color.

Difference in contact part numbers

What is the difference between SPH-002T-P0.5S and SPH-002T-P0.5L?

The difference is the insertion force. SPH-002T-P0.5S is the standard contact; SPH-002T-P0.5L is a low insertion force type contact.

These contacts do not share the same tooling.

How do I order the PH series SMT header to include a suction cap?

To order the top-entry, surface mount header of the PH series with removable suction cap (Kapton tape) for ease of pick-and-place vacuum nozzles, the part number would include an extra "T" after the packaging indicator.

For example:

Part number B2B-PH-SM4-TB (LF)(SN) does not include the suction cap.
Part number B2B-PH-SM4-TBT (LF)(SN) includes the suction cap.

JST cannot rework product you have already purchased without the suction cap.
