Key Parameters

Substitute Part Grouping Explanation

Substitution for LM2902DRCT in the Linear, Amplifiers category is governed by the following strictly matched parameters:

• Amplifier type
• Number of circuits
• Slew rate
• Gain bandwidth product
• Input bias current
• Input offset voltage
• Supply current
• Output current per channel
• Voltage supply span (minimum and maximum)
• Package/case type
• Mounting type
• Operating temperature range
• RoHS compliance
• Moisture sensitivity level

Substitute parts are selected only when these parameters are compatible with the main part number. Changes in product status such as Obsolete or Last Time Buy also influence the selection when maintaining long-term availability.

Parameter Comparison

Engineering Selection Recommendations

Component selection between LM2902DRCT and LM2902DR must consider product status and compliance attributes. LM2902DRCT is listed as Last Time Buy, indicating limited future availability. LM2902DR is classified as Obsolete, which places constraints on sourcing for high-volume or long-term applications. Both are ROHS3 Compliant with Moisture Sensitivity Level 1, suitable for unlimited floor life and compliant with current environmental regulations.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical when substituting LM2902DRCT in the Linear, Amplifiers category?
A1: The critical parameters for substitution include amplifier type, number of circuits, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current per channel, voltage supply span, operating temperature, mounting type, package/case, RoHS compliance, and moisture sensitivity level.

Q2: Are there any package compatibility issues with LM2902DR as a substitute?
A2: Both LM2902DRCT and LM2902DR use 14-SOIC (0.154", 3.90mm Width) packages, which are mechanically compatible for surface mount PCB assembly.

Q3: Does RoHS3 compliance affect substitute selection?
A3: Both LM2902DRCT and LM2902DR are ROHS3 Compliant, ensuring environmental compatibility for electronic manufacture and shipment.

Q4: What impact does “Last Time Buy” or “Obsolete” product status have on substitution?
A4: “Last Time Buy” indicates limited future availability, and “Obsolete” indicates discontinued production. Substitute selection should take into account availability and supply chain continuity for ongoing projects.

Q5: Are moisture sensitivity levels equivalent between LM2902DRCT and LM2902DR?
A5: Both devices have Moisture Sensitivity Level 1 (Unlimited), suitable for standard SMT assembly and storage conditions.

Q6: Is electrical performance identical between LM2902DRCT and LM2902DR?
A6: Differences exist in slew rate and input offset voltage; refer to the comparison table for exact values. All other key performance parameters are equivalent as listed above.
