General Purpose amplifier, 1 MHz gain bandwidth, 3 V to 32 V supply, 1.5 mA supply current, -55 to 125 °C operating temperature, 14-CDIP through-hole package.","salesMarkdown":"## Quad op-amp in a hermetic CDIP — what you're getting The Texas Instruments LM124AJ/PB is a quad general-purpose operational amplifier from the LinCMOS™ series, packaged in a 14-CDIP (0.300\", 7.62 mm) ceramic dual-in-line with through-hole mounting. Four independent amplifiers in one package, each with a 1 MHz gain-bandwidth product and 40 mA output current capability. Supply range spans 3 V to 32 V, drawing 1.5 mA total quiescent current. Input offset voltage is 2 mV typical, input bias current 45 nA. The -55 °C to 125 °C junction temperature range puts this squarely in the military / high-reliability tier — avionics, satellite, downhole instrumentation, or any sealed-environment board where a plastic SOIC won't cut it. The ceramic DIP handles thermal cycling and moisture resistance that plastic packages can't match. ## Supply voltage range — why it simplifies the BOM Supply span is 3 V to 32 V. ## 14-CDIP package — rework and handling notes The 14-CDIP (0.300\" body width, 7.62 mm row spacing) is a through-hole ceramic package. ## Active lifecycle — no LTB risk for new designs Product status is Active per the manufacturer. No last-time-buy notice, no end-of-life flag. This part can be specified into new production builds with confidence. ROHS3 compliant — no lead-free conversion concern for legacy Pb-free assembly lines.","metaTitle":"LM124AJ/PB Op Amp, 1 MHz, Quad, 14-CDIP, -55 to 125°C","metaDescription":"LM124AJ/PB quad general-purpose op-amp from TI LinCMOS™ series. 1 MHz GBP, 3-32 V supply, 14-CDIP hermetic package, -55 to 125°C.

The key difference is the package: LM124AJ/PB is a 14-CDIP (ceramic DIP), while LM124N is typically a plastic PDIP. They are pin-compatible in function and pinout, but the ceramic package is specified for hermetic / high-reliability environments. If your board originally used a plastic DIP and the environment doesn't require hermetic sealing, the LM124N is the direct drop-in. If the board was designed for a ceramic DIP socket, the LM124AJ/PB is the correct fi"},{"question":"Is LM124AJ/PB obsolete or EOL?","answer":"No. The product status is Active per the manufacturer.

No separate lead-free variant is needed — this part already meets the ROHS3 directive."},{"question":"When sourcing LM124AJ/PB, what's the closest functional second-source?","answer":"The INA4290A2IRGVR is a quad current-sense amplifier with a 1.1 MHz bandwidth and 2 V/µs slew rate, but it is a current-sense type, not a general-purpose op-amp, and it runs on a 2.7 V supply in a surface-mount package. It is not a pin-compatible or functional replacement for the LM124AJ/PB. For a general-purpose quad op-amp in a similar performance class, the TLV9352IDDFR (dual, 10.6 MHz) or TLV9351IDCKR (single, 3.5 MHz) are newer CMOS alternatives but in surface-mount packages and with fewer channels per package.
