REF5050AIDGKT Equivalent & Substitute Parts

Part Overview

The REF5050AIDGKT is a series voltage reference IC manufactured by Texas Instruments, designed to provide a fixed 5V output with ±0.1% tolerance. This component operates as a precision voltage reference in power management applications, with an active product status and full RoHS3 compliance. Alternative models become necessary when inventory constraints exist, specific packaging preferences are required, or when noise performance specifications must be evaluated against application requirements.

Key Parameters

Substitute Part Grouping Explanation

The REF5050AIDGKR qualifies as a parametric equivalent to the REF5050AIDGKT based on the following critical substitution criteria:

Matching Parameters:

• Identical output voltage (5V fixed)
• Identical output current rating (10 mA)
• Identical tolerance specification (±0.1%)
• Identical temperature coefficient (8 ppm/°C)
• Identical input voltage range (5.2V ~ 18V)
• Identical supply current (1.2 mA)
• Identical operating temperature range (-40°C ~ 125°C)
• Identical package type (8-VSSOP)
• Identical mounting type (Surface Mount)
• Identical RoHS and compliance status

Variance:

• Noise specification (0.1Hz to 10Hz): REF5050AIDGKT specifies 6µVpp/V; REF5050AIDGKR specifies 15µVpp/V

Both parts share the same base product number (REF5050) and are manufactured by Texas Instruments with identical electrical and mechanical specifications except for the noted noise performance difference.

Parameter Comparison

Engineering Selection Recommendations

Both the REF5050AIDGKT and REF5050AIDGKR maintain active product status with full ROHS3 compliance and REACH unaffected certification. Selection between these parts should be based on the following factors:

REF5050AIDGKT Selection Criteria:

• Applications requiring lower noise performance (6µVpp/V in the 0.1Hz to 10Hz band)
• Designs with stringent noise specifications in sensitive analog circuits

REF5050AIDGKR Selection Criteria:

• Applications where the higher noise specification (15µVpp/V) is acceptable
• Situations requiring higher inventory availability (32863 units versus 7218 units)
• Cost optimization scenarios where noise performance is not a limiting factor

Both parts are suitable for identical electrical and mechanical integration, with package compatibility confirmed across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can REF5050AIDGKR be used as a direct replacement for REF5050AIDGKT?

A: Yes, for applications where the noise specification of 15µVpp/V (0.1Hz to 10Hz) is acceptable. Both parts share identical output voltage, current rating, tolerance, temperature coefficient, input voltage range, supply current, operating temperature, and package specifications. The primary difference is the noise performance in the 0.1Hz to 10Hz band.

Q: What is the key difference between these two parts?

A: The REF5050AIDGKR has a higher noise specification (15µVpp/V) compared to the REF5050AIDGKT (6µVpp/V) in the 0.1Hz to 10Hz frequency band. All other electrical and mechanical parameters are identical.

Q: Are both parts available in the same package?

A: Yes. Both the REF5050AIDGKT and REF5050AIDGKR are supplied in the 8-VSSOP package (8-TSSOP, 8-MSOP with 0.118" width, 3.00mm) as surface mount components.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, carry MSL rating 2 (1 Year), and maintain active product status from Texas Instruments.

Q: Which part should I select for noise-sensitive applications?

A: The REF5050AIDGKT is specified for lower noise performance (6µVpp/V) and is the appropriate choice for applications with stringent noise requirements in the 0.1Hz to 10Hz band.

Q: Are there any differences in supply current or input voltage requirements?

A: No. Both parts require identical supply current (1.2 mA) and operate across the same input voltage range (5.2V ~ 18V).
