Engineering Selection Recommendations

LM60CIM3/NOPB (Texas Instruments): Direct equivalent with identical electrical specifications. Offers ROHS3 compliance and REACH unaffected status, addressing regulatory concerns of the original LM60CIM3. Product status is Obsolete, limiting long-term availability. Suitable for applications requiring exact parameter matching with improved compliance.

DS60R+T&R (Analog Devices Inc./Maxim Integrated): Active product with improved accuracy (±2°C vs. ±3°C) and ROHS3 compliance. Supply voltage range is narrower (2.7V ~ 5.5V) compared to the original. Includes standby mode feature. Recommended for new designs and applications where supply voltage remains within specification and improved accuracy is beneficial.

TC1047AVNBTR (Microchip Technology): Active product with ROHS3 compliance and improved accuracy (±2°C). Resolution is 10mV/°C (coarser than 6.25mV/°C). Supply voltage range is 2.5V ~ 5.5V. Suitable for applications where the wider resolution step is acceptable and supply voltage compatibility is confirmed.

TC1047VNBTR (Microchip Technology): Active product with ROHS3 compliance and improved accuracy (±2°C). Resolution is 10mV/°C. Supply voltage range is 2.7V ~ 4.4V (most restrictive). Suitable for low-voltage applications within the specified supply range where resolution tolerance permits substitution.

Frequently Asked Questions (FAQ)

Q: Can LM60CIM3/NOPB be used as a direct replacement for LM60CIM3?

A: Yes. Both parts share identical electrical specifications, temperature range, resolution, and package. The primary differences are product status (Obsolete vs. Not For New Designs) and compliance certifications (ROHS3 Compliant and REACH Unaffected vs. RoHS non-compliant and REACH Affected).

Q: What is the key difference between the LM60 series and TC1047 series substitutes?

A: The primary difference is resolution. LM60 devices output 6.25mV/°C, while TC1047 devices output 10mV/°C. This affects temperature measurement granularity. TC1047 parts also offer improved accuracy (±2°C vs. ±3°C) and active product status.

Q: Are the DS60R+T&R and TC1047 series pin-compatible with LM60CIM3?

A: Yes. All substitute parts use the SOT-23-3 package (TO-236-3, SC-59), ensuring mechanical and electrical pin compatibility. However, verify that the application's supply voltage and resolution requirements are met by the selected substitute.

Q: Which substitute is recommended for new designs?

A: DS60R+T&R, TC1047AVNBTR, and TC1047VNBTR all carry Active product status and ROHS3 compliance. Selection depends on supply voltage requirements and resolution tolerance. DS60R+T&R maintains 6.25mV/°C resolution matching the original. TC1047 variants offer improved accuracy but with 10mV/°C resolution.

Q: What supply voltage considerations apply when selecting a substitute?

A: The original LM60CIM3 operates at 2.7V ~ 10V. DS60R+T&R operates at 2.7V ~ 5.5V, TC1047AVNBTR at 2.5V ~ 5.5V, and TC1047VNBTR at 2.7V ~ 4.4V. Confirm the application's supply voltage falls within the substitute's specification before selection.

Q: Are there compliance or regulatory differences between these parts?

A: Yes. LM60CIM3 is RoHS non-compliant and REACH Affected. All substitutes (LM60CIM3/NOPB, DS60R+T&R, TC1047AVNBTR, TC1047VNBTR) are ROHS3 Compliant and REACH Unaffected, meeting modern regulatory requirements.
