REF6225IDGKR Equivalent & Substitute Parts

Part Overview

The REF6225IDGKR is a Series Voltage Reference IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This fixed 2.5V reference device delivers 4 mA output current with ±0.05% tolerance and operates across the 3V to 5.5V input range. The component is actively produced and widely used in precision analog circuits requiring stable voltage references. Substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across different packaging configurations or tape & reel options.

Engineering Selection Recommendations

Both REF6225IDGKR and REF6225IDGKT are active products manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is determined by procurement and assembly requirements:

REF6225IDGKR is suitable for standard component procurement and manual assembly workflows.
REF6225IDGKT is specified for high-volume automated assembly operations requiring tape & reel packaging.

Both devices maintain ROHS3 compliance and identical moisture sensitivity ratings. No functional or performance differences exist between the two part numbers. The choice between them depends solely on supply chain logistics and manufacturing process requirements.

Frequently Asked Questions (FAQ)

Q: Can REF6225IDGKT be used as a direct replacement for REF6225IDGKR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, tolerance, temperature coefficient, and noise performance. The only difference is packaging format (Tape & Reel vs. standard packaging). Electrical and mechanical compatibility is complete.

Q: What is the difference between REF6225IDGKR and REF6225IDGKT?

A: The parts differ only in packaging configuration. REF6225IDGKR uses standard packaging, while REF6225IDGKT is supplied in Tape & Reel (TR) format for automated assembly. All electrical parameters, pin configurations, and performance characteristics are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status, REACH unaffected designation, and Moisture Sensitivity Level 2 (1 Year) rating. Compliance certifications are equivalent.

Q: Which part should be selected for high-volume production?

A: REF6225IDGKT (Tape & Reel format) is recommended for high-volume automated assembly operations. REF6225IDGKR is suitable for standard procurement and lower-volume applications.

Q: Do these parts require different PCB footprints or layout considerations?

A: No. Both parts use the identical 8-VSSOP package with 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) mechanical specifications. PCB footprints, pin assignments, and layout requirements are identical.

Q: What is the operating temperature range for these voltage reference ICs?

A: Both REF6225IDGKR and REF6225IDGKT operate across 0°C to 70°C (TA). Temperature coefficient is 3 ppm/°C for both parts.
