REF5040AIDGKT Equivalent & Substitute Parts

Part Overview

The REF5040AIDGKT is a series voltage reference IC manufactured by Texas Instruments, designed for precision analog applications requiring a fixed 4.096V output. This active product operates as a fixed reference with ±0.1% tolerance and supports input voltages from 4.296V to 18V. The device is packaged in 8-VSSOP surface mount configuration and is ROHS3 compliant. Substitute parts are identified when packaging format or supply chain availability requires alternative sourcing while maintaining identical electrical performance and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the REF5040AIDGKT is determined by strict equivalence across all electrical parameters and mechanical specifications. The substitute part REF5040AIDGKR maintains identical performance characteristics:

Critical Equivalence Parameters:

  • Fixed output voltage: 4.096V
  • Output tolerance: ±0.1%
  • Output current capability: 10 mA
  • Temperature coefficient: 8 ppm/°C
  • Input voltage range: 4.296V ~ 18V
  • Supply current: 1.2 mA
  • Operating temperature range: -40°C ~ 125°C
  • Package type: 8-VSSOP (8-TSSOP, 8-MSOP)
  • Mounting type: Surface Mount

The only difference between the main part and substitute is the packaging format: REF5040AIDGKT is supplied in Tape & Reel (TR) format, while REF5040AIDGKR is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the same base product number REF5040 and share identical electrical and mechanical characteristics.

Engineering Selection Recommendations

Both REF5040AIDGKT and REF5040AIDGKR are active products from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between these parts is based on packaging and supply chain requirements:

REF5040AIDGKT is appropriate for high-volume production environments utilizing automated tape and reel handling systems.

REF5040AIDGKR is appropriate for lower-volume applications, prototype development, or environments using cut tape and Digi-Reel® supply formats.

Both parts maintain ROHS3 compliance and REACH unaffected status. MSL rating of 2 (1 Year) applies to both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Are REF5040AIDGKT and REF5040AIDGKR electrically identical?

A: Yes. Both parts share the same base product number (REF5040) and deliver identical electrical performance: 4.096V fixed output, ±0.1% tolerance, 10 mA output current, and 8 ppm/°C temperature coefficient across the -40°C to 125°C operating range.

Q: What is the difference between these two part numbers?

A: The difference is packaging format only. REF5040AIDGKT is supplied in Tape & Reel (TR) format, while REF5040AIDGKR is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the same 8-VSSOP package for surface mount assembly.

Q: Can I substitute REF5040AIDGKR for REF5040AIDGKT in my design?

A: Yes, from an electrical and mechanical standpoint. The parts are pin-compatible and functionally equivalent. Substitution is valid when packaging format change does not conflict with assembly or supply chain requirements.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL rating of 2 (1 Year). Regulatory and environmental compliance status is identical.

Q: What input voltage range does this reference IC support?

A: The input voltage range is 4.296V to 18V for both REF5040AIDGKT and REF5040AIDGKR.

Q: What is the maximum output current specification?

A: Both parts support a maximum output current of 10 mA.
