Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging format. Ensure the procurement documentation explicitly states compliance with MIL-PRF-19500/559 for military qualification. Confirm that the RoHS3 status aligns with project environmental requirements. Validate the manufacturer source to ensure authenticity of the Microchip Technology product.

Selection Notes

Select this component when a quad NPN array is required for space-constrained surface-mount designs. The high junction temperature rating makes it suitable for harsh environment applications. Compare against through-hole alternatives like the standard 2N6989 if PCB layout flexibility allows. Verify that the 50V voltage rating and 800mA current capacity meet the specific circuit load requirements.

Part Context

This part belongs to the 2N6989 family of multiple PNP silicon switching transistors produced by Microchip Technology. The JANS prefix indicates a specific military grade variant within this series. Other variants in the family include different packaging options and qualification levels, such as JAN or JANTX designations, offering flexibility for various reliability tiers.

Replacement Considerations

Direct functional substitutes may include other qualified quad NPN arrays from Microchip. Verify pinout compatibility and electrical parameters before substitution. Cross-reference with equivalent parts listed in official replacement guides.
