Engineering Selection Recommendations

Recommended Primary Substitute: SA56004ED,118

SA56004ED,118 is the direct active production equivalent from NXP USA Inc. This part maintains identical electrical specifications, temperature operating range, resolution, accuracy, and 8-SOIC package configuration as the SA56004GD,118. The only differences are product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging). This part is ROHS3 compliant and carries REACH Unaffected status, matching the original part's compliance profile. Selection of SA56004ED,118 requires no design modifications and ensures maximum compatibility.

Secondary Substitutes: TMP411 Series (TMP411ADR, TMP411BDR)

TMP411ADR and TMP411BDR from Texas Instruments are active production alternatives suitable for applications where enhanced specifications are acceptable. These parts provide 11-bit resolution (versus 10-bit), improved accuracy (±1°C at 15°C ~ 85°C versus ±2°C), and extended remote temperature sensing capability (-64°C ~ 191°C). Both maintain I2C/SMBus compatibility, 8-SOIC packaging, and ROHS3 compliance. TMP411ADR is available in Cut Tape & Digi-Reel packaging; TMP411BDR is available in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can SA56004ED,118 be used as a direct replacement for SA56004GD,118?

A: Yes. SA56004ED,118 is the active production equivalent from NXP USA Inc. with identical electrical specifications, temperature range (-40°C ~ 125°C), resolution (10-bit), accuracy (±2°C / ±3°C), and 8-SOIC package. The only differences are product status (Active) and packaging format (Tape & Reel). No design modifications are required.

Q: What are the key differences between SA56004GD,118 and TMP411ADR?

A: TMP411ADR provides higher resolution (11-bit versus 10-bit), improved accuracy (±1°C versus ±2°C at 15°C ~ 85°C), and extended remote temperature sensing (-64°C ~ 191°C versus -40°C ~ 125°C). Both maintain I2C/SMBus output, 8-SOIC packaging, and -40°C ~ 125°C local temperature range. TMP411ADR has lower minimum supply voltage (2.7V versus 3V). These enhancements are compatible with SA56004GD,118 applications.

Q: Can LM86CIMX/NOPB replace SA56004GD,118 in all applications?

A: No. LM86CIMX/NOPB operates within 0°C ~ 85°C local temperature range, which does not cover the full -40°C lower limit of SA56004GD,118. Supply voltage is also limited to 3V ~ 3.6V versus 3V ~ 5.5V. This part is suitable only for applications where local temperature sensing does not require operation below 0°C and supply voltage remains within 3V ~ 3.6V.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm Width) package is a surface mount configuration with 8 pins. All substitute parts listed maintain this identical package footprint and pin configuration, ensuring mechanical and electrical compatibility on printed circuit boards without layout modifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (SA56004ED,118, TMP411 series, LM86CIMX/NOPB, LM89CIMX/NOPB, LM95245CIMX/NOPB) are ROHS3 compliant. Compliance status is consistent across all alternatives.

Q: What is the difference between I2C/SMBus and SMBus output types?

A: I2C/SMBus indicates compatibility with both I2C and SMBus protocols. SMBus indicates compatibility with SMBus protocol only. SMBus is a subset of I2C with stricter timing specifications. Parts specified as SMBus-only (LM86, LM89, LM95245 series) are compatible with SMBus applications but may have different protocol implementation details compared to I2C/SMBus parts.

Q: Can TMP411BDR be used in applications requiring the full -40°C ~ 125°C temperature range?

A: Yes. TMP411BDR supports -40°C ~ 125°C local temperature sensing range, matching SA56004GD,118. The part also extends remote temperature sensing to -64°C ~ 191°C. TMP411BDR is suitable for applications requiring the full temperature envelope of the original part.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active status indicates the part is in current production and available for new designs. Obsolete status indicates the part is no longer manufactured. For new designs and long-term production applications, active status parts are recommended to ensure sustained supply chain availability.
