SUPU Tier-1 distributor Jarwey｜Fixed screw PCB terminal 450612 vs pluggable 450907
Jarwey is a SUPU Tier-1 distributor and can help with shortlisting, datasheets, samples, and lead time.
On a 5.0 mm PCB terminal block, the next split is mechanical, not another pitch family. 450612 is a one-piece screw terminal whose package line already says 5.0 mm-12 pin. 450907 is a two-piece set in the product photo — a wire plug seated on a separate pin header — and its package line is blank. The push-button versus screw note on 435304 / 435318 stays in the other article. This page does not rebuild that table.
None of these pages carries a datasheet. Ask Jarwey for the drawing. The table below uses only words printed on the page and what the photo shows. Current, voltage, and wire size are not copied from a neighbor.
Fixed screw block and pluggable header
| Part | Printed on the page | Photo | Do not extend | Page |
|---|---|---|---|---|
| 450612 | Package line: 5.0 mm-12 pin. The description is only the brand name. No clamp sentence, no current, no voltage, no wire range | One piece. Screw heads sit over the wire entries; solder pins leave the bottom | The 12 positions and the 5.0 mm pitch belong to this page only | 531 |
| 450907 | Package line is a dash. The description is the generic connector sentence (contact resistance, mating life, vibration, RoHS). No pitch, no pin count, no current, no counterpart number | Two pieces. A wire plug sits on a black pin header, with a row of entries and a row of solder pins | The last two characters of the model are not a package line. Counting openings in the photo is not a printed rating | 835 |
| 450907/010 | A separate catalog page. The body says there is no detailed description. The /010 suffix is not defined | No product photo | Do not fill 450907 pitch or pin count from this suffix page | 538 |
Unplug first, then count pins
The harness has to leave the board. Use the 450907 photo as the entry. The page already shows a plug and a header. Pitch and position count still wait for the datasheet. Do not paste 5.0 mm-12 pin into the blank package field.
The wires stay soldered. Use 450612. The package line already states 5.0 mm and 12 positions, and the screw heads are in the photo. Current and wire cross-section are still absent, so temperature rise stays a sample check.
Neither page prints a counterpart part number. This note is not a drop-in approval.
Selection checklist
- Decide whether the cable must disconnect without desoldering.
- Read the package line before the model number. 450612 states 5.0 mm-12 pin. 450907 is a dash.
- Match the photo. 450612 is one screw block. 450907 is a plug on a header.
- Do not copy 12 positions or 5.0 mm onto 450907. The model suffix is not a package line.
- Neither page states current, voltage, or wire size. Do not borrow 10 A / 320 V or 0.14–1.5 mm² from the 435304 page.
- 450907/010 does not define its suffix and has no photo. It cannot complete 450907.
- Request the datasheet from Jarwey. Check the footprint, position count, retention, and temperature rise on a sample before the BOM changes.
