TMP300BIDBVR Equivalent & Substitute Parts

Part Overview

The TMP300BIDBVR is a programmable thermostat with active low open drain output, manufactured by Texas Instruments in SOT-23-6 surface mount packaging. This component operates across a wide supply voltage range of 1.8 V to 18 V and is designed for temperature monitoring applications requiring configurable switching thresholds. The device is currently in Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative models become necessary when inventory constraints occur or when specific accuracy requirements differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMP300BIDBVR is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Package / Case: SOT-23-6 (physical and electrical pin compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Output Type: Open Drain (circuit interface requirement)
• Output Polarity: Active Low (logic level compatibility)
• Switching Temperature: Programmable (functional requirement)
• Voltage - Supply: 1.8 V ~ 18 V (power supply compatibility)
• Current - Supply: 110µA (power budget compatibility)
• Operating Temperature Range: -40°C ~ 150°C (environmental specification)
• Manufacturer: Texas Instruments (design and qualification basis)

The TMP300AIDBVR qualifies as a direct substitute because it matches all critical parameters. Variations in accuracy specification (±4°C versus ±6°C) and product status do not prevent functional substitution when the application tolerance permits the improved accuracy of the substitute part.

Engineering Selection Recommendations

TMP300BIDBVR (Primary Selection): This part is the recommended choice for new designs. It maintains Active product status with full manufacturing support and long-term availability assurance. RoHS3 compliance and unlimited moisture sensitivity rating ensure compatibility with modern assembly and storage requirements.

TMP300AIDBVR (Substitute Selection): This part is suitable for replacement applications where the TMP300BIDBVR is unavailable. The improved accuracy specification (±4°C) provides enhanced performance compared to the primary part. However, the Not For New Designs status indicates this part is in end-of-life phase. Use this substitute only when inventory of the primary part is exhausted and the application can accommodate the legacy product status. Both parts carry identical RoHS3 and REACH compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can TMP300AIDBVR be used as a direct replacement for TMP300BIDBVR in existing designs?

A: Yes. Both parts share identical package, mounting type, output configuration, supply voltage range, supply current, and operating temperature specifications. The improved accuracy of the TMP300AIDBVR (±4°C versus ±6°C) makes it functionally compatible for any application currently using the TMP300BIDBVR.

Q: What is the significance of the "Not For New Designs" status on the TMP300AIDBVR?

A: This status indicates the part is in end-of-life phase and is not recommended for incorporation into new product designs. However, it remains suitable for replacement and repair of existing systems. Inventory availability may be limited compared to Active status parts.

Q: Are there any differences in packaging or handling between these two parts?

A: Both parts use SOT-23-6 surface mount packaging with identical pin configuration and moisture sensitivity level (MSL 1, Unlimited). No differences in handling, storage, or assembly procedures apply.

Q: How does the accuracy difference affect substitution decisions?

A: The TMP300AIDBVR provides tighter accuracy (±4°C) compared to the TMP300BIDBVR (±6°C). Applications with loose tolerance requirements can use either part interchangeably. Applications requiring the ±6°C specification must use the TMP300BIDBVR.

Q: Are both parts RoHS compliant?

A: Yes. Both TMP300BIDBVR and TMP300AIDBVR carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements.
