REF5050IDGKT Equivalent & Substitute Parts

Part Overview

The REF5050IDGKT is a Series Voltage Reference IC manufactured by Texas Instruments, designed to provide a fixed 5V output with ±0.05% tolerance. This precision voltage reference operates across an input range of 5.2V to 18V and delivers a maximum output current of 10 mA. The device is housed in an 8-VSSOP surface mount package and is classified as Active product status, making it suitable for applications requiring stable reference voltages in power management circuits.

Identifying equivalent and substitute parts becomes necessary when managing inventory constraints, ensuring supply chain continuity, or optimizing procurement across multiple production batches. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure seamless integration into existing designs.

Substitute Part Grouping Explanation

Substitution of the REF5050IDGKT is permissible with parts that maintain strict equivalence across the following critical parameters:

• Reference Type: Series
• Output Type: Fixed
• Voltage - Output: 5V (fixed)
• Current - Output: 10 mA
• Tolerance: ±0.05%
• Temperature Coefficient: 3ppm/°C
• Operating Temperature Range: -40°C ~ 125°C (TA)
• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

The REF5050IDGKR qualifies as a parametric equivalent substitute. Both parts are manufactured by Texas Instruments, share the same base product number (REF5050), and maintain identical electrical specifications for output voltage, current capacity, tolerance, and temperature coefficient. Input voltage range and noise characteristics may vary within acceptable engineering margins, provided all critical performance parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the REF5050IDGKT and REF5050IDGKR maintain Active product status from Texas Instruments, ensuring continued manufacturer support and availability. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

The REF5050IDGKR presents an equivalent alternative with identical electrical performance specifications. The minor variation in minimum input voltage (5.3V versus 5.2V) does not affect substitution suitability for applications operating within the specified input range. Selection between these parts should be based on inventory availability, packaging preference (Cut Tape or Digi-Reel), and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can REF5050IDGKR be used as a direct replacement for REF5050IDGKT?

A: Yes. Both parts share identical output voltage (5V), tolerance (±0.05%), temperature coefficient (3ppm/°C), output current (10 mA), and operating temperature range (-40°C ~ 125°C). Package and mounting specifications are equivalent. The parts are electrically and mechanically interchangeable.

Q: What is the difference between the input voltage ranges?

A: REF5050IDGKT specifies 5.2V ~ 18V input, while REF5050IDGKR specifies 5.3V ~ 18V input. This 0.1V difference in minimum input voltage does not affect substitution for applications operating within both ranges. Verify your circuit's input voltage to confirm compatibility.

Q: Are both parts available in the same packaging options?

A: Yes. Both REF5050IDGKT and REF5050IDGKR are available in Cut Tape (CT) and Digi-Reel packaging formats. Both use the 8-VSSOP supplier device package with 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) case designation.

Q: Do these parts meet current compliance requirements?

A: Both parts are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level is rated at 2 (1 Year) for both parts, meeting standard handling and storage requirements for surface mount components.

Q: What determines substitution eligibility for REF5050 series parts?

A: Substitution eligibility is determined by equivalence in reference type, output type, fixed output voltage, output current capacity, tolerance, temperature coefficient, operating temperature range, package designation, and compliance certifications. All these parameters must match between the original and substitute part.
