Packaging and Reliability
How to compare package size, pin compatibility, thermal resistance, MSL, solder profile, qualification grade, lifetime, FIT, and reliability tests.
Back to Engineering FAQsView Engineering GuidesPin count does not guarantee the same pinout, land pattern, exposed pad, height, thermal path, moisture sensitivity, or assembly process. Package drawings and ordering codes should be checked before treating parts as compatible.
Reliability values need model, temperature, voltage, mission profile, confidence level, and qualification context. A lower FIT rate is only meaningful when the assumptions are comparable.
Preserve MSL, reflow profile, peak temperature, solderability, package material, lead finish, underfill or board assumptions, and any qualification standard or test method reference.
