Electrical Parameters (Must Match Exactly):

• Fixed output voltage: 3.3V
• Output current capability: 4 mA
• Voltage tolerance: ±0.05%
• Temperature coefficient: 3 ppm/°C
• Input voltage range: 4.65V ~ 5.5V
• Supply current: 1.1 mA
• Operating temperature range: 0°C ~ 70°C

Mechanical Parameters (Must Match Exactly):

• Package type: 8-VSSOP
• Mounting type: Surface Mount
• Physical dimensions: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)

Compliance & Certification (Must Match):

• RoHS3 Compliance
• Moisture Sensitivity Level: 2 (1 Year)
• REACH Status: REACH Unaffected

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both REF6233IDGKR and REF6233IDGKT are active products from Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts should be based on:

Availability & Inventory: REF6233IDGKT currently has higher inventory availability (1108 Pcs) compared to REF6233IDGKR (810 Pcs), making it suitable for high-volume procurement scenarios.

Compliance Status: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for industrial and commercial applications.

Packaging Designation: The difference between IDGKR and IDGKT designations reflects packaging reel specifications (Tape & Reel format). Both are surface-mount compatible with identical physical dimensions and electrical performance.

Application Continuity: Direct substitution is supported without circuit redesign, PCB layout modification, or firmware updates, as all critical parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can REF6233IDGKT be used as a direct replacement for REF6233IDGKR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (3.3V), tolerance (±0.05%), temperature coefficient (3 ppm/°C), and 8-VSSOP packaging. No circuit modifications are required.

Q: What is the difference between the IDGKR and IDGKT part number suffixes?

A: The suffix designates the packaging reel configuration for tape and reel delivery. Both parts use identical 8-VSSOP surface-mount packages with the same physical dimensions (0.118", 3.00mm width). The difference is in reel specifications only.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both REF6233IDGKR and REF6233IDGKT operate across 0°C to 70°C (TA), with identical temperature coefficient performance of 3 ppm/°C.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 2 (1 Year) rating.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical performance, output specifications, input voltage range (4.65V ~ 5.5V), and supply current (1.1 mA) ensure full interchangeability without design changes.

Q: What is the maximum output current for these reference ICs?

A: Both parts provide 4 mA maximum output current with ±0.05% tolerance and 3 µVp-p noise performance in the 0.1Hz to 10Hz band.
