LM26CIM5-VHA Temperature Sensor Equivalent & Substitute Parts

Part Overview

The LM26CIM5-VHA is a thermostat temperature sensor manufactured by Texas Instruments, designed for thermal management applications requiring active-low open-drain output. This component operates as an over-temperature detection device with a fixed switching temperature of 90°C and is classified as obsolete. Due to its obsolete product status, identifying equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution of the LM26CIM5-VHA is determined by strict equivalence across the following critical parameters:

Switching temperature threshold: 90°C
Output configuration: Open drain, active-low logic
Supply voltage range: 2.7 V ~ 5.5 V
Accuracy specification: ±3°C
Package format: SOT-23-5 surface mount
Thermal operating range: -55°C ~ 125°C

The substitute part LM26CIM5-VHA/NOPB maintains identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the main part's standard packaging, and compliance status differs between RoHS non-compliant and ROHS3 compliant versions.

Engineering Selection Recommendations

The LM26CIM5-VHA/NOPB is a direct functional equivalent suitable for applications requiring identical thermal switching behavior and electrical interface characteristics. Selection between the main part and substitute should be based on:

Packaging requirements: The substitute is supplied in Tape & Reel format, appropriate for automated assembly processes. The main part uses standard packaging suitable for manual or mixed-volume assembly.

Regulatory compliance: The substitute meets ROHS3 compliance standards, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the ROHS3-compliant substitute is the appropriate selection.

Inventory and procurement: Both parts are obsolete. Availability should be verified with authorized distributors. The substitute currently maintains higher inventory levels (1772 Pcs vs. 2400 Pcs), though both are listed as new original stock.

Frequently Asked Questions (FAQ)

Q: Can LM26CIM5-VHA/NOPB be used as a direct replacement for LM26CIM5-VHA?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: switching temperature (90°C), accuracy (±3°C), output configuration (open drain, active low), supply voltage range (2.7 V ~ 5.5 V), and SOT-23-5 package format. The difference is packaging format (Tape & Reel vs. standard) and RoHS compliance status.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB designation indicates lead-free, RoHS3-compliant manufacturing. This part meets environmental and regulatory requirements for applications in regions with RoHS directives.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts maintain identical thermal switching characteristics (90°C threshold, ±3°C accuracy), supply current (16µA), and operating temperature range (-55°C ~ 125°C).

Q: Which part should be selected for new designs?

A: Since both parts are obsolete, neither is recommended for new designs. However, if design continuity requires these specifications, the LM26CIM5-VHA/NOPB is preferable due to ROHS3 compliance and current inventory availability.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel and standard packaging formats contain identical components. The difference is only in delivery and handling method. Tape & Reel is optimized for high-volume automated assembly, while standard packaging is suitable for lower-volume or manual assembly processes.

Q: What is the MSL rating and why does it matter?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity. These components do not require special moisture-controlled storage or handling procedures.
