SN104633DR Equivalent & Substitute Parts

Part Overview

The SN104633DR is a prototype component manufactured by Texas Instruments, currently designated as Last Time Buy status. This part is ROHS3 compliant with MSL 1 (Unlimited moisture sensitivity level). Due to its Last Time Buy status and limited availability, identifying functionally equivalent substitute components is essential for design continuity and procurement planning. The primary substitute identified is the LM2902DR, a general-purpose operational amplifier from Rohm Semiconductor.

Substitute Part Grouping Explanation

Substitution of the SN104633DR with the LM2902DR is based on the following criteria:

Compliance Alignment: Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity level, ensuring equivalent environmental and regulatory compliance.

Functional Category: The LM2902DR is classified as a Linear Amplifier, specifically a General Purpose Amplifier with 4 circuits in a 14-SOIC package configuration.

Availability and Status: While the SN104633DR is Last Time Buy, the LM2902DR maintains active inventory (90,223 pcs in stock), though it is marked as Obsolete. This substitution addresses supply chain continuity concerns.

Key Electrical Parameters for Substitution:

• Supply Voltage Range: 3V to 32V
• Operating Temperature Range: -40°C to 125°C
• Slew Rate: 0.3V/µs
• Gain Bandwidth Product: 1.2 MHz
• Input Bias Current: 20 nA
• Input Offset Voltage: 1 mV
• Output Current per Channel: 30 mA
• Supply Current: 1 mA

Parameter Comparison

Engineering Selection Recommendations

Compliance Verification: Both SN104633DR and LM2902DR meet ROHS3 compliance requirements and carry identical MSL 1 ratings, confirming regulatory equivalence for applications requiring these certifications.

Availability Consideration: The SN104633DR's Last Time Buy status necessitates transition planning. The LM2902DR, despite Obsolete designation, maintains substantial inventory (90,223 pcs), providing a viable bridge for procurement continuity.

Cross-Manufacturer Substitution: Selection of LM2902DR represents a cross-manufacturer substitution from Texas Instruments to Rohm Semiconductor. This substitution is valid based on provided compliance and environmental specifications.

REACH and Trade Compliance: The LM2902DR carries REACH Unaffected status and EAR99 ECCN classification, meeting standard export and trade requirements.

Frequently Asked Questions (FAQ)

Q: Can LM2902DR directly replace SN104633DR in all applications?

A: Substitution validity depends on application-specific electrical requirements. Both components share equivalent RoHS3 compliance and MSL 1 ratings. Detailed electrical parameter matching (supply voltage, operating temperature, slew rate, gain bandwidth product) must be verified against your circuit design specifications.

Q: What is the significance of Last Time Buy and Obsolete status?

A: Last Time Buy indicates the SN104633DR will no longer be manufactured; existing inventory represents the final supply. Obsolete status for LM2902DR indicates it is no longer in active production. Both statuses require proactive component selection and inventory planning.

Q: Are there packaging differences between these components?

A: The LM2902DR is specified in 14-SOIC (0.154", 3.90mm Width) package. The SN104633DR packaging is not specified in available data. Package compatibility must be confirmed before substitution.

Q: What electrical parameters are critical for substitution decisions?

A: Key parameters include supply voltage range (3V to 32V for LM2902DR), operating temperature range (-40°C to 125°C), slew rate (0.3V/µs), gain bandwidth product (1.2 MHz), and output current capability (30 mA per channel). These must align with your circuit requirements.

Q: Is cross-manufacturer substitution from Texas Instruments to Rohm Semiconductor acceptable?

A: Cross-manufacturer substitution is acceptable when compliance certifications (ROHS3, MSL 1) and electrical parameters match application requirements. Verification against specific circuit design parameters is mandatory.
