LM2902KPW Equivalent & Substitute Parts

Part Overview

The LM2902KPW is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-TSSOP surface-mount package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The LM2902KPW operates across a wide supply voltage range (3V to 26V) and temperature range (-40°C to 125°C), making it suitable for general analog signal processing applications requiring low input bias current and moderate bandwidth.

Due to Last Time Buy status, identifying functionally equivalent substitute parts is essential for design continuity and long-term component availability. Substitute parts must maintain compatibility across electrical performance parameters, package form factor, and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q1: Can I use LM2902MT/NOPB as a direct replacement for LM2902KPW?

A: LM2902MT/NOPB is electrically compatible in the same 14-TSSOP package. However, the operating temperature range is limited to -40°C to 85°C (versus -40°C to 125°C for LM2902KPW). Use this substitute only if your application does not require operation above 85°C. Input bias current is higher (45 nA vs. 20 nA), which may affect precision analog circuits.

Q2: What is the difference between 14-TSSOP and 14-LSSOP packages?

A: Both packages have identical pin counts and similar body dimensions (0.173" width, 4.40mm). The primary difference is in lead configuration and thermal characteristics. 14-LSSOP (used by BA2902 series) has slightly different lead geometry. PCB footprints are not interchangeable without layout verification. Consult package datasheets before substituting.

Q3: Why do some substitute parts show higher input bias current (90 nA vs. 20 nA)?

A: Input bias current variation reflects different semiconductor process technology. Higher bias current may affect high-impedance input circuits. For applications with input impedances below 1 MΩ, this difference is typically negligible. For precision instrumentation or high-impedance sensor interfaces, select parts with 20 nA bias current (LM2902KPW, LM2902KPWR, BA2902 series, LM2902WPT, LM2902YPT).

Q4: Can I substitute LM2902YPT (60 mA output) for LM2902KPW (30 mA output)?

A: Yes. LM2902YPT provides higher output current capability and is therefore suitable for applications requiring up to 60 mA per channel. The part is pin-compatible in the same 14-TSSOP package. LM2902YPT includes automotive qualification (AEC-Q100), making it suitable for both commercial and automotive applications.

Q5: What does "Last Time Buy" status mean for LM2902KPW?

A: Last Time Buy indicates that Texas Instruments has discontinued production and will not manufacture additional units beyond existing inventory. The 2,492 pieces currently in stock represent the final available supply. For long-term design continuity, transition to an active-status substitute part such as LM2902VDTBR2G or LM2902YPT.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant and REACH unaffected, matching the environmental compliance of LM2902KPW.

Q7: Which substitute part has the best slew rate performance?

A: LM2902YPT and LM2902WPT both offer 0.4 V/µs slew rate (versus 0.5 V/µs for LM2902KPW). LM2902KPW maintains the highest slew rate specification. If slew rate is critical to your application, verify that the 0.4 V/µs specification of STMicroelectronics parts meets your circuit requirements.

Q8: Can I use BA2902FV-E2 in a high-speed application?

A: BA2902FV-E2 has a gain bandwidth product of 500 kHz, which is significantly lower than LM2902KPW (1.2 MHz). This part is suitable only for low-frequency applications (below 100 kHz). For applications requiring bandwidth above 500 kHz, use LM2902VDTBR2G, LM2902WPT, or LM2902YPT.

Q9: What is the difference between LM2902DTBR2G and LM2902VDTBR2G?

A: Both parts are manufactured by onsemi in 14-TSSOP package with identical electrical specifications. The primary difference is operating temperature range: LM2902DTBR2G operates -40°C to 105°C, while LM2902VDTBR2G operates -40°C to 125°C. Select LM2902VDTBR2G for applications requiring full 125°C upper temperature limit.

Q10: Is packaging (Tube vs. Tape & Reel) important for substitution?

A: Packaging affects handling and assembly processes but not electrical performance. Tube packaging (LM2902KPW) is suitable for manual assembly or low-volume production. Tape & Reel packaging (LM2902MTX/NOPB, LM2902VDTBR2G) is required for automated pick-and-place assembly in high-volume manufacturing. Select packaging based on your production process requirements.
