Substitute Part Grouping Explanation

Substitute parts for the REF6033IDGKR are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Fixed 3.3V output voltage
• ±0.05% tolerance specification
• 4 mA output current capability
• 5ppm/°C temperature coefficient
• 3µVp-p noise performance (0.1Hz to 10Hz)
• 4.65V ~ 5.5V input voltage range
• 1.1mA supply current
• -40°C ~ 125°C operating temperature range
• 8-VSSOP package configuration
• Surface mount mounting type
• Active product status
• ROHS3 compliance

The REF6033IDGKR and its substitute share identical base product number (REF6033) and are differentiated only by packaging format designation (IDGKR vs. IDGKT), representing different tape and reel configurations from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both the REF6033IDGKR and REF6033IDGKT are active products from Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts should be based on:

• Tape and reel configuration requirements specific to your assembly process
• Current inventory availability and lead time considerations
• Supply chain logistics and procurement preferences

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility across applications. The electrical performance, including output voltage accuracy, temperature stability, and noise characteristics, is identical between both variants.

Frequently Asked Questions (FAQ)

Q: Can REF6033IDGKT be used as a direct replacement for REF6033IDGKR?

A: Yes. Both parts are electrically and mechanically identical. The difference lies in tape and reel packaging format. Direct substitution is valid for circuit design and electrical performance.

Q: What is the difference between IDGKR and IDGKT designations?

A: These designations represent different tape and reel configurations from Texas Instruments. The electrical specifications, package type (8-VSSOP), and performance characteristics are identical.

Q: Are there any compatibility concerns when switching between these parts?

A: No compatibility concerns exist. Both parts use the same 8-VSSOP package with identical pin configuration, footprint, and electrical characteristics. PCB layout and schematic design remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both REF6033IDGKR and REF6033IDGKT are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 2, 1 Year).

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 125°C (TA), suitable for industrial and extended temperature applications.

Q: Are there any supply chain advantages to selecting one variant over the other?

A: Selection should be based on current inventory levels and procurement lead times. REF6033IDGKT currently has higher inventory availability (1769 Pcs) compared to REF6033IDGKR (744 Pcs).
