Substitute Part Grouping Explanation

Substitution of the TL431IDMR2 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Adjustable
• Voltage Range: 2.495V to 36V
• Output Current: 100mA
• Tolerance: ±2.2%
• Temperature Coefficient: 50ppm/°C Typical
• Operating Temperature Range: -40°C to 85°C
• Package: 8-MSOP surface mount

The TL431IDMR2G qualifies as a direct substitute, maintaining identical electrical specifications and mechanical compatibility. The primary distinction lies in RoHS compliance status and manufacturing date codes.

Parameter Comparison

Engineering Selection Recommendations

The TL431IDMR2G serves as the direct functional equivalent to the TL431IDMR2. Both devices share identical electrical performance specifications and mechanical compatibility within the 8-MSOP package footprint.

The TL431IDMR2G offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant RoHS status of the original TL431IDMR2. This distinction is relevant for applications subject to RoHS directives or procurement policies requiring compliant components.

Both parts maintain equivalent moisture sensitivity levels and export classification codes, ensuring consistent handling and logistics requirements.

Frequently Asked Questions (FAQ)

Q: Can TL431IDMR2G replace TL431IDMR2 in existing designs?
