39-31-0048
Mini-Fit Jr. Vertical Header, 4.20mm Pitch, Dual Row, 4 Circuits, without Snap-in Plastic Peg PCB Lock, Gold, Natural
Part Aliases: Molex 0039310048 Molex 5566-04BGS-210
The 39-31-0048, a Mini-Fit Jr. Vertical Header designed for high-performance connectivity in electronic applications. With a pitch of 4.20mm and featuring a dual-row configuration, this header offers reliable power and signal transmission. Boasting 4 circuits and constructed without a snap-in plastic peg PCB lock, it facilitates easy installation. The gold-plated brass contacts ensure excellent conductivity, rated for up to 9A and 600V. Engineered for durability, the nylon body is suitable for a wide range of operating environments, withstanding temperatures from -40 to 105°C. PCB retention is enhanced through a built-in locator, while polarization to both the PCB and mating part guarantees proper alignment. RoHS compliant and lead-free process capable, this header is a dependable choice for wire-to-board connections in various electronic devices.

Product Change Notice
| Effective Date | Description of Change | Download |
|---|---|---|
| 08/17/2022 | 511610 - Change to product. currently vertical header housings have drain hole and non-drain hole version housing. the drain holes are no longer needed they were used in the past when PCB boards were being washed and are no longer needed. therefore we are eliminating the drain hole option going forward | Download |
| 07/18/2022 | 510809 - Change to product. current vertical header housings have a drain hole and non-drain hole version housing the drain holes are no longer needed (they were used in the past when PCB boards were being washed and are no longer needed) therefore we are eliminating the drain hole option going forward | Download |
| 02/14/2022 | 511607 - Retraction of PCN 510948. This PCN is a retraction/ recall of PCN 510809 communicated on 1/18/22 for "current vertical header housings have a drain hole and non-drain hole version housing the drain holes are no longer needed (they were used in the past when PCB boards were being washed and are no longer needed) therefore we are eliminating the drain hole option going forward." the reason for retraction is that part numbers that did not contain the drain hole option were included in the impacted parts list used to create pcn 510809 a new pcn will be created and customers will be notified | Download |
| 12/24/2018 | 506262 - Capacity Change or Tool Replacement. This letter is to inform you that another set of tooling is being added to meet the current and future demands of this product.
