Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMP411ADG4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Sensor Type: Digital, Local/Remote
• Package / Case: 8-SOIC form factor
• Output Interface: I2C/SMBus protocol
• Mounting Type: Surface Mount

Secondary Compatibility Parameters:

• Sensing Temperature - Local: -40°C ~ 125°C range
• Sensing Temperature - Remote: -64°C ~ 191°C range
• Voltage Supply: 2.7V ~ 5.5V range
• Resolution: 11 bits
• Accuracy: ±1°C to ±2.5°C

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalents (Texas Instruments TMP411 Series): Parts TMP411AD and TMP411ADR maintain identical electrical specifications, temperature ranges, resolution, and accuracy as the main part. These differ only in packaging format (Tube vs. Cut Tape & Digi-Reel) and product status (Obsolete vs. Active).

Category 2 - Functional Alternatives (Cross-Manufacturer): Parts SA56004AD,118, SA56004CD,118, and SA56004ED,118 (NXP) provide equivalent local/remote temperature sensing with I2C/SMBus interface in 8-SOIC packaging. These parts operate within the same temperature range and supply voltage but feature 10-bit resolution and ±2°C to ±3°C accuracy.

Category 3 - Limited Compatibility: Part ADM1032ARZ-REEL (Analog Devices) shares the 8-SOIC package and SMBus interface but operates within a narrower temperature range (0°C ~ 100°C local, 0°C ~ 120°C remote) with 7-bit resolution. This part is suitable only for applications not requiring the full -40°C to 125°C operating range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): TMP411ADR is the primary recommended substitute. It maintains identical electrical specifications and temperature ranges as the TMP411ADG4 while offering active product status and superior availability (68,738 units in stock). The part is supplied in Cut Tape & Digi-Reel format, suitable for both manual and automated assembly processes. ROHS3 compliance is maintained.

For Extended Temperature Range Applications: TMP411AD provides equivalent specifications to TMP411ADG4 with the same 11-bit resolution and ±1°C accuracy. Although classified as obsolete, it remains available in Tube packaging (2,400 units in stock) and maintains ROHS3 compliance. This option is suitable when existing inventory management systems require Tube format.

For Cost-Optimized Designs (Non-Critical Accuracy): SA56004AD,118, SA56004CD,118, and SA56004ED,118 offer functional equivalence with reduced resolution (10 bits) and slightly lower accuracy (±2°C to ±3°C). These NXP parts operate within the full -40°C to 125°C local temperature range and maintain I2C/SMBus compatibility. Supply voltage minimum is 3V (versus 2.7V for TMP411 series). All three variants are active products with strong inventory availability (1,074 to 2,200 units).

Not Recommended for Direct Substitution: ADM1032ARZ-REEL operates within a restricted temperature range (0°C ~ 100°C local) and provides only 7-bit resolution. This part is suitable only for applications that do not require the full -40°C to 125°C operating range specified for the TMP411ADG4.

Frequently Asked Questions (FAQ)

Q: Can TMP411ADR be used as a direct drop-in replacement for TMP411ADG4?

A: Yes. TMP411ADR maintains identical electrical specifications, temperature ranges, resolution, and accuracy. The primary difference is packaging format (Cut Tape & Digi-Reel vs. 8-SOIC) and product status (Active vs. Obsolete). Pin configuration and I2C/SMBus protocol remain unchanged.

Q: What is the key difference between TMP411 series and SA56004 series substitutes?

A: TMP411 parts (TMP411ADG4, TMP411AD, TMP411ADR) provide 11-bit resolution with ±1°C accuracy. SA56004 parts provide 10-bit resolution with ±2°C to ±3°C accuracy. Both families support the full -40°C to 125°C local temperature range and I2C/SMBus interface. SA56004 parts require minimum 3V supply voltage, while TMP411 parts operate from 2.7V.

Q: Is the 8-SOIC package identical across all substitute parts?

A: Yes. All substitute parts use the 8-SOIC package with 0.154" width (3.90mm). Pin assignments and footprint compatibility are maintained across TMP411 and SA56004 families. ADM1032ARZ-REEL also uses 8-SOIC packaging.

Q: Can ADM1032ARZ-REEL replace TMP411ADG4 in all applications?

A: No. ADM1032ARZ-REEL operates within 0°C ~ 100°C local temperature range, which is narrower than the TMP411ADG4 specification of -40°C ~ 125°C. This part is suitable only for applications that do not require extended low-temperature operation below 0°C or high-temperature operation above 100°C.

Q: What compliance certifications are maintained across substitute parts?

A: TMP411ADG4, TMP411AD, TMP411ADR, SA56004AD,118, SA56004CD,118, and SA56004ED,118 are all ROHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99. Compliance status for ADM1032ARZ-REEL is not specified in available documentation.

Q: Are there packaging format options for substitute parts?

A: Yes. TMP411AD is supplied in Tube format. TMP411ADR is supplied in Cut Tape & Digi-Reel format. SA56004 variants are supplied in Tape & Reel format. ADM1032ARZ-REEL is supplied in Bulk format. Selection depends on assembly process requirements and inventory management systems.

Q: What is the inventory status for each substitute part?

A: TMP411ADR has the highest availability (68,738 units). SA56004CD,118 has 2,200 units. TMP411AD has 2,400 units. ADM1032ARZ-REEL has 7,538 units. SA56004AD,118 and SA56004ED,118 have 1,074 and 1,900 units respectively. All parts are classified as new original stock.
