TS3000B3ANRG Temperature Sensor Equivalent & Substitute Parts

Part Overview

The TS3000B3ANRG is a digital temperature sensor manufactured by Renesas Electronics Corporation, designed for local temperature measurement across the -20°C to 125°C range with I2C/SMBus output interface. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The sensor operates on 3V to 3.6V supply voltage with 11-bit resolution and ±1°C accuracy, packaged in an 8-VFQFPN (2x3) surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS3000B3ANRG are selected based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Sensor type: Digital, local temperature measurement
• Temperature sensing range: -20°C to 125°C minimum coverage
• Output interface: I2C/SMBus serial communication
• Supply voltage compatibility: Overlap with 3V to 3.6V range
• Package type: Surface mount, 8-pin VFQFPN/WDFN/TDFN variants
• Mounting footprint: 2x3mm form factor

Substitute Parts Identified:

1. AT30TSE002B-MAH-T (Microchip Technology) – Primary substitute with active product status
2. STTS2004B2DN3F (STMicroelectronics) – Active alternative with DDR memory application support
3. MCP9844T-BE/MNY (Microchip Technology) – Active variant with extended supply voltage range
4. MCP9844T-BE/MNYAB (Microchip Technology) – Active variant, tape & reel packaging
5. MCP9844T-BE/MNYAA (Microchip Technology) – Active variant, tape & reel packaging

Parameter Comparison

Engineering Selection Recommendations

AT30TSE002B-MAH-T is the primary recommended substitute. This Microchip part maintains the -20°C to 125°C sensing range and I2C/SMBus interface compatibility. It operates within the 3V to 3.6V supply range with extended lower voltage capability (2.7V minimum). The 10-bit resolution represents a minor reduction from the original 11-bit specification. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance and MSL 3 rating are suitable for standard manufacturing environments.

STTS2004B2DN3F provides an alternative from STMicroelectronics with identical temperature range coverage (-20°C to 125°C) and I2C output. This part includes DDR memory application support and maintains MSL 1 rating. Supply voltage range extends to 2.2V minimum, providing greater flexibility in power-constrained applications. Active product status and ROHS3 compliance support production continuity.

MCP9844T-BE/MNY, MCP9844T-BE/MNYAB, and MCP9844T-BE/MNYAA are functionally equivalent Microchip variants with extended operating temperature range (-40°C to 125°C) and lower minimum supply voltage (1.7V). These parts include output alarm and fan control features. All three variants maintain I2C compatibility and MSL 1 rating. Selection between these variants depends on packaging requirements: MCP9844T-BE/MNY uses cut tape & digi-reel packaging, while MNYAB and MNYAA use tape & reel packaging.

Frequently Asked Questions (FAQ)

Q: Can AT30TSE002B-MAH-T directly replace TS3000B3ANRG without firmware changes?

A: Yes, for applications operating within the -20°C to 125°C range. Both parts use I2C/SMBus interface and operate on 3V to 3.6V supply. The 10-bit resolution of AT30TSE002B-MAH-T versus 11-bit of TS3000B3ANRG represents a 0.1°C LSB difference, acceptable for most thermal management applications. Verify register map compatibility with your firmware implementation.

Q: What is the difference between the three MCP9844 variants?

A: MCP9844T-BE/MNY, MCP9844T-BE/MNYAB, and MCP9844T-BE/MNYAA are functionally identical. The suffix designates packaging format: MNY indicates cut tape & digi-reel, while MNYAB and MNYAA indicate tape & reel configurations. Select based on your procurement and assembly process requirements.

Q: Does STTS2004B2DN3F require different PCB layout compared to TS3000B3ANRG?

A: Both parts use 8-pin surface mount packages with 2x3mm footprints. Package designations differ (TDFN versus VFQFPN), but pin pitch and thermal pad dimensions are compatible. Verify exact footprint dimensions in component datasheets before finalizing PCB layout.

Q: Which substitute offers the best accuracy specification?

A: AT30TSE002B-MAH-T matches the original ±1°C accuracy specification at 75°C to 95°C operating range. STTS2004B2DN3F and all MCP9844 variants specify ±3°C maximum accuracy. For applications requiring ±1°C accuracy across the full -20°C to 125°C range, AT30TSE002B-MAH-T is the appropriate selection.

Q: Are all substitutes ROHS3 compliant?

A: Yes. AT30TSE002B-MAH-T, STTS2004B2DN3F, MCP9844T-BE/MNY, MCP9844T-BE/MNYAB, and MCP9844T-BE/MNYAA all carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Q: What is the impact of MSL rating differences?

A: TS3000B3ANRG and STTS2004B2DN3F carry MSL 1 (unlimited shelf life). AT30TSE002B-MAH-T carries MSL 3 (168-hour floor life after moisture exposure). MCP9844 variants carry MSL 1. For standard manufacturing environments with controlled humidity, MSL 3 presents no practical limitation. Extended storage or high-humidity environments favor MSL 1 rated parts.
