TMCS1101A2BQDR Equivalent & Substitute Parts

Part Overview

The TMCS1101A2BQDR is a Hall Effect current sensor manufactured by Texas Instruments, designed for bidirectional AC/DC current measurement with a sensing range of ±22.5A. This surface-mount device operates across a supply voltage range of 3V to 5.5V and delivers ratiometric voltage output with 100mV/A sensitivity. The component is housed in an 8-SOIC package measuring 0.154" (3.90mm width) and is currently in active production status.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and packaging standards. Substitute parts enable design flexibility, support supply chain continuity, and accommodate different procurement requirements while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMCS1101A2BQDR are identified through parametric equivalence. All substitute parts maintain identical electrical specifications across the critical parameters that define functional compatibility: current sensing range (±22.5A), output characteristics (ratiometric voltage at 100mV/A sensitivity), frequency response (80kHz), linearity (±0.05%), supply voltage range (3V ~ 5.5V), response time (6.5µs), operating temperature range (-40°C ~ 125°C), and package form factor (8-SOIC, 0.154" width).

The substitutes differ in packaging configuration and product qualification status. These differences address specific procurement scenarios, supply chain requirements, and application-level certifications without affecting the core electrical performance or mechanical fit of the component.

Parameter Comparison

Engineering Selection Recommendations

TMCS1101A2BQDRQ1 is suitable for applications requiring automotive-grade qualification. This variant carries AEC-Q100 certification and ROHS3 compliance, making it appropriate for automotive and industrial applications with stringent reliability requirements. The Cut Tape and Digi-Reel packaging configuration supports automated assembly processes. This part is in active production status with substantial inventory availability.

TMCS1101A2BQDT is available in Tape & Reel packaging for high-volume manufacturing environments. This configuration is optimized for pick-and-place assembly operations. The part carries ROHS3 compliance and REACH Unaffected status. However, this variant is designated as Last Time Buy, indicating limited future availability. Selection of this part should account for long-term supply chain planning.

TMCS1101A2BQDR (original part number) is available in bulk packaging configuration. This variant is in active production status and supports standard procurement workflows. Selection depends on packaging requirements and assembly process compatibility.

All three variants are electrically and mechanically equivalent and interchangeable at the circuit level when package form factor compatibility is confirmed.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. The TMCS1101A2BQDR, TMCS1101A2BQDRQ1, and TMCS1101A2BQDT are parametrically equivalent. All three parts deliver identical electrical performance across current sensing range (±22.5A), output sensitivity (100mV/A), frequency response (80kHz), linearity (±0.05%), supply voltage range (3V ~ 5.5V), response time (6.5µs), and operating temperature range (-40°C ~ 125°C). Substitution is valid at the circuit design level.

Q: What is the difference between these part numbers?

A: The differences are limited to packaging configuration and product qualification status. TMCS1101A2BQDR uses bulk packaging, TMCS1101A2BQDRQ1 uses Cut Tape and Digi-Reel packaging with automotive-grade AEC-Q100 qualification, and TMCS1101A2BQDT uses Tape & Reel packaging. These distinctions address procurement, assembly, and application-level certification requirements rather than electrical performance.

Q: Can I substitute TMCS1101A2BQDT for TMCS1101A2BQDR in a new design?

A: Electrical substitution is valid. However, TMCS1101A2BQDT is designated Last Time Buy, indicating limited future production. For new designs requiring long-term component availability, TMCS1101A2BQDR or TMCS1101A2BQDRQ1 are preferred selections.

Q: Which part should I select for automotive applications?

A: TMCS1101A2BQDRQ1 is qualified for automotive use with AEC-Q100 certification. This variant is appropriate for automotive and safety-critical applications. The other variants are suitable for general industrial and consumer applications.

Q: Are all three parts compatible with my PCB layout?

A: Yes, all three parts use the identical 8-SOIC package form factor (0.154", 3.90mm width) and surface-mount configuration. PCB footprints and land patterns are identical across all variants. Substitution requires no layout modifications.

Q: What is the difference between bulk, Cut Tape, and Tape & Reel packaging?

A: Bulk packaging is supplied in standard quantities without tape or reel configuration. Cut Tape and Digi-Reel packaging provides components on continuous tape in cut lengths, suitable for automated assembly. Tape & Reel packaging supplies components on continuous reels optimized for high-volume pick-and-place operations. Selection depends on assembly process requirements and production volume.

Q: Do all parts have the same compliance certifications?

A: TMCS1101A2BQDRQ1 and TMCS1101A2BQDT carry ROHS3 compliance and REACH Unaffected status. TMCS1101A2BQDR does not specify these certifications. For applications requiring documented RoHS or REACH compliance, TMCS1101A2BQDRQ1 or TMCS1101A2BQDT are appropriate selections.

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

A: TMCS1101A2BQDRQ1 has 8212 pieces in stock. TMCS1101A2BQDR has 3300 pieces in stock. TMCS1101A2BQDT has 855 pieces in stock. Inventory levels support immediate procurement for all variants.
