Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SE95DP,118 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Sensing temperature range: -55°C ~ 125°C (full range match required)
• Output interface: I2C/SMBus digital communication
• Package type: 8-TSSOP or equivalent surface mount packages
• Mounting configuration: Surface mount
• Supply voltage compatibility: Overlap with 2.8V ~ 5.5V range
• RoHS3 compliance and MSL rating

Substitute Categories:

Category 1 - Direct NXP Replacement (Active Status): PCT2075DP,118 maintains NXP manufacturing continuity with identical temperature range, I2C/SMBus interface, and 8-TSSOP packaging. Resolution differs at 11 bits versus 13 bits, with improved accuracy specification (±1°C / ±2°C). Supply voltage range is 2.7V ~ 5.5V.

Category 2 - Analog Devices Alternative (Active Status): DS620U+ and DS620U+T&R provide 12-bit resolution with enhanced accuracy (±0.5°C / ±2°C) and I2C output. These devices operate on 1.7V ~ 4.6V supply and feature one-shot capability with programmable resolution. Package designation is 8-uMAX-EP|8-uSOP-EP with exposed pad.

Category 3 - Microchip Temperature Monitoring Solutions (Active Status): MCP9844T-BE/MNY, MCP9844T-BE/MNYAA, and MCP9844T-BE/MNYAB are internal sensor-based temperature monitoring ICs with -40°C ~ 125°C sensing range, I2C output, and 8-TDFN packaging. These devices operate on 1.7V ~ 3.6V supply with ±3°C accuracy and include alarm and fan control outputs.

Parameter Comparison

Engineering Selection Recommendations

PCT2075DP,118 is the primary recommended substitute. It maintains NXP manufacturing lineage, active product status, and identical temperature sensing range (-55°C ~ 125°C) with I2C/SMBus interface compatibility. The 8-TSSOP package matches the original footprint. Resolution reduction from 13 bits to 11 bits and improved accuracy specification (±1°C / ±2°C) represent functional enhancements for most applications. Supply voltage range (2.7V ~ 5.5V) provides compatibility with existing 2.8V ~ 5.5V designs.

DS620U+ and DS620U+T&R are suitable alternatives for applications where lower supply voltage operation (1.7V ~ 4.6V) is acceptable. These Analog Devices devices offer superior accuracy (±0.5°C / ±2°C) and 12-bit resolution with programmable resolution capability. Package differences (8-uMAX-EP|8-uSOP-EP versus 8-TSSOP) require PCB layout verification. The DS620U+T&R variant with Cut Tape & Digi-Reel packaging provides higher inventory availability (5300 pcs).

MCP9844T-BE variants (MNY, MNYAA, MNYAB) from Microchip Technology are applicable for designs where internal sensor-based temperature monitoring is acceptable. These devices operate on 1.7V ~ 3.6V supply with -40°C ~ 125°C range (narrower low-temperature specification than SE95DP,118). The 8-TDFN package requires PCB redesign. All three variants maintain active product status and ROHS3 compliance.

All substitute options maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and REACH unaffected status, ensuring regulatory continuity with the original SE95DP,118 design.

Frequently Asked Questions (FAQ)

Q: Can PCT2075DP,118 be used as a direct drop-in replacement for SE95DP,118?

A: PCT2075DP,118 is functionally compatible for most applications. Both devices share identical temperature sensing range (-55°C ~ 125°C), I2C/SMBus interface, 8-TSSOP package, and surface mount configuration. The resolution difference (11 bits versus 13 bits) and improved accuracy (±1°C / ±2°C versus ±1°C / ±3°C) represent functional improvements. Supply voltage range compatibility (2.7V ~ 5.5V overlaps with 2.8V ~ 5.5V) requires verification for designs operating below 2.8V.

Q: What are the key differences between NXP and Analog Devices temperature sensor options?

A: PCT2075DP,118 (NXP) maintains the original 8-TSSOP package and higher supply voltage range (2.7V ~ 5.5V). DS620U+ and DS620U+T&R (Analog Devices) offer superior accuracy (±0.5°C / ±2°C), lower supply voltage operation (1.7V ~ 4.6V), and programmable resolution features. Package differences (8-uMAX-EP|8-uSOP-EP) require PCB layout changes. Both maintain -55°C ~ 125°C temperature range and I2C interface compatibility.

Q: Are Microchip MCP9844T-BE variants suitable replacements?

A: MCP9844T-BE variants provide I2C interface and active product status but differ in critical parameters. Sensing temperature range is -40°C ~ 125°C (narrower low-temperature specification), sensor type is internal rather than local, and package is 8-TDFN (2x3) requiring PCB redesign. These devices are applicable only for applications where the -40°C minimum temperature is acceptable and package changes are feasible.

Q: What packaging considerations apply when selecting substitutes?

A: SE95DP,118 uses 8-TSSOP package. PCT2075DP,118 maintains this package for direct PCB compatibility. DS620U+ variants use 8-uMAX-EP|8-uSOP-EP package with exposed pad, requiring PCB layout verification. MCP9844T-BE variants use 8-TDFN (2x3) package, necessitating PCB redesign. Package selection impacts thermal performance, board space, and manufacturing processes.

Q: How do supply voltage ranges affect substitution decisions?

A: SE95DP,118 operates on 2.8V ~ 5.5V. PCT2075DP,118 operates on 2.7V ~ 5.5V, providing full compatibility. DS620U+ and MCP9844T-BE variants operate on lower voltage ranges (1.7V ~ 4.6V and 1.7V ~ 3.6V respectively). Designs operating at 2.8V or above can use any substitute. Designs operating below 2.8V require DS620U+ or MCP9844T-BE variants with corresponding power supply modifications.

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

A: SE95DP,118 is obsolete, indicating discontinued manufacturing and limited future availability. All substitute options maintain active product status, ensuring ongoing supply chain support, manufacturing continuity, and long-term availability. Active status is critical for new designs and sustained production requirements.
