Engineering Selection Recommendations

Primary Recommendation: LM2902MT/NOPB

The LM2902MT/NOPB is the direct equivalent of the LM2902MT, manufactured by Texas Instruments with identical electrical specifications and 14-TSSOP packaging. This part maintains active product status and is the preferred choice for direct replacement in existing designs. Both parts share the same base product number (LM2902), LinCMOS™ series designation, and ROHS3 compliance. The /NOPB suffix indicates lead-free, halogen-free packaging.

Secondary Recommendation: LM2902MTX/NOPB

The LM2902MTX/NOPB provides an alternative from Texas Instruments with identical electrical performance but delivered in tape and reel format. This packaging format is suitable for automated assembly environments and high-volume production. The part maintains active status and full compatibility with the original LM2902MT specification.

Extended Temperature Alternative: LM2902VDTBR2G

The LM2902VDTBR2G, manufactured by onsemi, extends the operating temperature range to -40°C to 125°C while maintaining 1 MHz gain bandwidth product and 40 mA output current per channel. This part is delivered in tape and reel format and is suitable for applications requiring enhanced thermal performance. Input bias current is specified at 90 nA, which remains within acceptable substitution parameters.

Automotive-Grade Alternative: LM2902WYPT

The LM2902WYPT, manufactured by STMicroelectronics, is qualified to AEC-Q100 automotive standards and carries automotive-grade designation. This part features push-pull output configuration, 1.3 MHz gain bandwidth product, and extended temperature range to 125°C. Supply voltage maximum is specified at 30V. This part is suitable for automotive and harsh-environment applications requiring automotive qualification.

High Output Current Alternative: LM2902YPT

The LM2902YPT, manufactured by STMicroelectronics, provides 60 mA output current per channel, exceeding the original 40 mA specification. This part carries automotive-grade qualification and AEC-Q100 certification. Supply voltage maximum is 30V. This part is suitable for applications requiring higher output drive capability.

Compliance and Certification Status:

All recommended substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original LM2902MT. Moisture sensitivity level is rated at MSL 1 (Unlimited) across all parts. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001.

Frequently Asked Questions (FAQ)

Q: Can LM2902MT/NOPB be used as a direct replacement for LM2902MT?

A: Yes. The LM2902MT/NOPB is manufactured by Texas Instruments with identical electrical specifications, package type (14-TSSOP), and functional performance. The /NOPB designation indicates lead-free, halogen-free packaging. Both parts are pin-compatible and functionally equivalent.

Q: What is the difference between tube and tape & reel packaging formats?

A: Tube packaging delivers components in plastic tubes suitable for manual handling and lower-volume applications. Tape and reel packaging delivers components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment used in high-volume manufacturing. Electrical performance is identical; packaging format selection depends on assembly process requirements.

Q: Can I substitute LM2902DTBR2G for LM2902MT in my design?

A: LM2902DTBR2G, manufactured by onsemi, maintains the same 14-TSSOP package, 1 MHz gain bandwidth product, and 40 mA output current per channel. However, input bias current is specified at 90 nA compared to 45 nA for the original part. Operating temperature range extends to 125°C. This part is suitable for substitution if your application can tolerate the higher input bias current specification and does not require the original -40°C to 85°C temperature range limitation.

Q: What are the advantages of LM2902WYPT over the original LM2902MT?

A: LM2902WYPT offers automotive-grade qualification (AEC-Q100), extended operating temperature range to 125°C, higher gain bandwidth product (1.3 MHz), and push-pull output configuration. Input bias current is lower at 20 nA. These enhancements make it suitable for automotive and demanding industrial applications. Supply voltage maximum is 30V compared to 32V for the original part.

Q: Is LM2902YPT compatible with LM2902MT?

A: LM2902YPT is pin-compatible and maintains the 14-TSSOP package and 1.3 MHz gain bandwidth product. The primary difference is higher output current per channel (60 mA versus 40 mA). This part is suitable for applications requiring higher output drive capability. Supply voltage maximum is 30V. Automotive-grade qualification and AEC-Q100 certification are included.

Q: Why does BA2902SFV-E2 have different package designation (14-LSSOP vs 14-TSSOP)?

A: BA2902SFV-E2, manufactured by Rohm Semiconductor, uses 14-LSSOP (Leadless Small-Outline Package) designation, which is mechanically and electrically compatible with 14-TSSOP footprints. Both packages have identical 0.173" (4.40mm) width and pin spacing. However, gain bandwidth product is lower at 500 kHz, and output current per channel is 30 mA. This part is suitable for substitution only if your application can tolerate reduced bandwidth and output current specifications.

Q: What does "Last Time Buy" status mean for LM2902MT?

A: Last Time Buy status indicates that Texas Instruments has announced discontinuation of the LM2902MT. Customers have a final opportunity to purchase remaining inventory before the part is completely removed from production. After the Last Time Buy date, the part will no longer be available from the manufacturer. Identifying and qualifying substitute parts is necessary to ensure long-term design continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance and REACH unaffected status, consistent with the original LM2902MT. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, indicating no moisture sensitivity precautions are required during storage or handling.

Q: Can NCV2902DTBR2G be used in commercial applications?

A: NCV2902DTBR2G is manufactured by onsemi and maintains the same electrical specifications as LM2902MT (1 MHz gain bandwidth product, 40 mA output current, 3-32V supply range). This part is suitable for commercial applications and carries active product status. Extended temperature range to 125°C provides additional thermal margin for demanding environments.
