Substitute Part Grouping Explanation

Substitution of the REF4132A40DBVRQ1 is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Fixed output voltage of 4.096V
• Output current capability of 10 mA
• Voltage tolerance of ±0.05%
• Temperature coefficient of 12 ppm/°C
• Noise specifications: 15 µVp-p (0.1Hz to 10Hz) and 24 µVrms (10Hz to 10kHz)
• Input voltage operating range compatibility
• Supply current of 100 µA

Mechanical Equivalence Criteria:

• SOT-23-5 package (SC-74A, SOT-753)
• Surface mount configuration
• Pin-compatible footprint

Compliance Equivalence Criteria:

• Active product status
• RoHS3 compliance
• Moisture Sensitivity Level 2 (1 Year)
• REACH unaffected status

The REF4132A40DBVR meets all electrical and mechanical equivalence requirements. The primary distinction between the main part and substitute is the packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) and Digi-Reel® format. Both parts share identical electrical specifications and the same base product number (REF4132).

Parameter Comparison

*The substitute part specifies a minimum input voltage of 4.146V compared to 4.05V for the main part. Applications requiring operation below 4.146V input voltage must use the main part REF4132A40DBVRQ1.

Engineering Selection Recommendations

REF4132A40DBVRQ1 (Tape & Reel Format): Select this part for high-volume production runs and automated assembly processes where Tape & Reel packaging is standard. This part is actively produced with AEC-Q100 automotive qualification and is suitable for automotive-grade applications requiring precision voltage reference functionality.

REF4132A40DBVR (Cut Tape & Digi-Reel® Format): Select this part for lower-volume applications, prototype development, or when Cut Tape packaging is preferred. This part maintains identical electrical specifications and automotive-grade compliance. The minimum input voltage specification of 4.146V must be verified against application requirements.

Substitution Compatibility: Both parts are electrically and mechanically equivalent for applications where the input voltage remains at or above 4.146V. The choice between them is determined by packaging requirements and supply chain logistics rather than functional performance. Both parts carry active product status and full compliance certifications (RoHS3, REACH unaffected, AEC-Q100).

Frequently Asked Questions (FAQ)

Q: Can REF4132A40DBVR be used as a direct replacement for REF4132A40DBVRQ1?

A: Yes, for applications where the input voltage is 4.146V or higher. Both parts are electrically identical with matching output voltage (4.096V), tolerance (±0.05%), temperature coefficient (12 ppm/°C), and noise specifications. The primary difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). If your application requires input voltage operation below 4.146V, the main part REF4132A40DBVRQ1 must be used.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated assembly. Cut Tape (CT) and Digi-Reel® packaging supplies components on cut segments of carrier tape, suitable for lower-volume production and manual assembly. Both formats use identical SOT-23-5 packages with the same pin configuration and footprint.

Q: Are both parts suitable for automotive applications?

A: Yes. Both REF4132A40DBVRQ1 and REF4132A40DBVR carry AEC-Q100 automotive qualification and are classified as automotive-grade components. Both are actively produced and comply with RoHS3 and REACH requirements.

Q: What is the minimum input voltage requirement for each part?

A: REF4132A40DBVRQ1 operates with input voltage from 4.05V to 5.5V. REF4132A40DBVR operates with input voltage from 4.146V to 5.5V. If your circuit operates below 4.146V input, use REF4132A40DBVRQ1.

Q: Are the pin configurations identical between these parts?

A: Yes. Both parts use the SOT-23-5 package (SC-74A, SOT-753) with identical pin assignments. They are pin-compatible and require no PCB layout modifications for substitution.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL rating of 2 with a 1-year shelf life. This indicates moderate moisture sensitivity requiring standard moisture control during storage and handling.

Q: Can these parts be substituted in either direction?

A: Substitution from REF4132A40DBVR to REF4132A40DBVRQ1 is always compatible. Substitution from REF4132A40DBVRQ1 to REF4132A40DBVR requires verification that the application input voltage remains at or above 4.146V.
