REF6145IDGKR Equivalent & Substitute Parts

Part Overview

The REF6145IDGKR is a series voltage reference integrated circuit manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This fixed 4.5V reference IC delivers ±0.05% tolerance with 4.6 mA output current in an 8-VSSOP surface mount package. The device is actively produced and maintains ROHS3 compliance with REACH unaffected status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitute parts for the REF6145IDGKR are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Critical Matching Parameters:

• Fixed output voltage of 4.5V
• Voltage tolerance of ±0.05%
• Output current capability of 4.6 mA
• Temperature coefficient of 8 ppm/°C
• Input voltage range of 4.75V ~ 5.5V
• 8-VSSOP package configuration
• Surface mount mounting type
• Active product status
• ROHS3 compliance

The REF6145IDGKT meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, package dimensions, and compliance certifications, making them directly interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both REF6145IDGKR and REF6145IDGKT are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on availability and packaging format (Tape & Reel). Both devices maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The REF6145IDGKR currently maintains 990 units in stock, while the REF6145IDGKT maintains 925 units. Either part is suitable for direct substitution in fixed 4.5V reference applications requiring ±0.05% tolerance and 4.6 mA output current within the -40°C to 125°C operating range.

Frequently Asked Questions (FAQ)
