Parameter Comparison

Engineering Selection Recommendations

The LM2902DR2G is the direct substitute for the SC2902NG based on the following engineering criteria:

Electrical Compatibility: Both devices operate across the identical supply voltage range (3V to 32V) and contain four general-purpose amplifier circuits. The LM2902DR2G provides specified electrical characteristics (1 MHz gain bandwidth product, 90 nA input bias current, 2 mV input offset voltage, and 40 mA output current per channel) that establish the performance baseline for this device family.

Mechanical Compatibility: Both parts utilize the 14-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90mm). Direct PCB footprint compatibility is assured.

Compliance and Regulatory Status: Both devices maintain REACH Unaffected status, EAR99 ECCN classification, and MSL Level 1 (Unlimited) moisture sensitivity rating. The LM2902DR2G holds RoHS3 Compliance certification, indicating adherence to current environmental standards.

Product Status Advantage: The LM2902DR2G carries Active product status with substantial inventory availability (205,100 pieces), ensuring long-term supply chain continuity compared to the obsolete SC2902NG.

Frequently Asked Questions (FAQ)

Q: Can the LM2902DR2G be used as a direct replacement for the SC2902NG in existing designs?

A: Yes. The LM2902DR2G is a direct substitute. Both devices share identical package geometry (14-SOIC), supply voltage range (3V to 32V), circuit count (4 amplifiers), and mounting type (surface mount). PCB footprints are interchangeable without modification.

Q: What is the primary reason for substituting the SC2902NG?

A: The SC2902NG is classified as obsolete. The LM2902DR2G is the active equivalent from the same manufacturer (onsemi) and provides assured long-term availability and supply chain stability.

Q: Are there any electrical performance differences between these parts?

A: The LM2902DR2G provides documented electrical specifications (1 MHz gain bandwidth product, 90 nA input bias current, 2 mV input offset voltage, 40 mA output current per channel, and -40°C to 105°C operating temperature range). The SC2902NG does not specify these parameters in available documentation. Both devices operate within the same 3V to 32V supply range.

Q: Is the packaging identical between the two parts?

A: Yes. Both the SC2902NG and LM2902DR2G use the 14-SOIC package with 0.154" width and 3.90mm physical dimensions. The LM2902DR2G is supplied in Cut Tape (CT) and Digi-Reel® packaging formats.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both devices are REACH Unaffected, classified as EAR99 for export control purposes, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. The LM2902DR2G additionally holds RoHS3 Compliance certification.

Q: What is the inventory status of the substitute part?

A: The LM2902DR2G has 205,100 pieces in stock as new original inventory, ensuring immediate availability and supporting production schedules without supply constraints.
