MS5837-02BA21 Equivalent & Substitute Parts

Part Overview

The MS5837-02BA21 is an active, board-mount absolute pressure sensor manufactured by TE Connectivity Measurement Specialties. This 24-bit digital pressure sensor operates within the 4.35 PSI to 17.4 PSI (30 kPa to 120 kPa) absolute pressure range and communicates via I2C interface. The device is temperature compensated and housed in a 4-SMD module package suitable for surface mount applications. Finding equivalent substitute parts is necessary to address supply chain flexibility, packaging format preferences, and inventory availability while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution of the MS5837-02BA21 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Identical pressure measurement range: 4.35 PSI ~ 17.4 PSI (30 kPa ~ 120 kPa) absolute
• Identical output type: I2C digital interface
• Identical output resolution: 24 bit
• Identical accuracy specification: ±0.007 PSI (±0.05 kPa)
• Identical supply voltage range: 1.5 V ~ 3.6 V
• Identical maximum pressure rating: 145.04 PSI (1000 kPa)
• Identical operating temperature range: -20°C ~ 85°C

Mechanical Equivalence Requirements:

• Identical mounting type: Surface Mount
• Identical package form: 4-SMD Module
• Identical termination style: SMD (SMT) Tab
• Identical pressure type: Absolute
• Identical feature set: Temperature Compensated

Compliance Equivalence Requirements:

• Active product status
• ROHS3 Compliant
• Moisture Sensitivity Level 1 (Unlimited)

The only allowable variation is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), which does not affect electrical or mechanical performance. All substitute parts must belong to the MS5837 series and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The MS583702BA01-50 is a direct parametric equivalent to the MS5837-02BA21. Both parts are manufactured by TE Connectivity Measurement Specialties, belong to the active MS5837 series, and maintain identical electrical specifications, mechanical form factor, and compliance certifications.

The sole difference between these parts is packaging format. The MS5837-02BA21 is supplied in Tape & Reel (TR) format, while the MS583702BA01-50 is supplied in Cut Tape (CT) & Digi-Reel® format. This packaging distinction does not affect component functionality, performance, or board-level integration.

Selection between these equivalent parts should be based on procurement requirements, inventory availability, and packaging format preferences for manufacturing processes. Both parts satisfy identical design requirements for absolute pressure measurement applications requiring I2C digital output, 24-bit resolution, and temperature compensation within the 4.35 PSI to 17.4 PSI operating range.

Frequently Asked Questions (FAQ)

Q: Can MS583702BA01-50 be used as a direct replacement for MS5837-02BA21 in existing designs?

A: Yes. The MS583702BA01-50 is electrically and mechanically identical to the MS5837-02BA21. All electrical specifications, pressure measurement range, I2C interface, 24-bit output resolution, accuracy, supply voltage requirements, operating temperature range, and physical package dimensions are equivalent. Direct substitution in PCB designs and circuit implementations is supported.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments or alternative reel formats, suitable for lower-volume orders or mixed-component procurement. Both packaging formats contain identical components with no functional differences.

Q: Are there any compliance or certification differences between these parts?

A: No. Both MS5837-02BA21 and MS583702BA01-50 are ROHS3 Compliant, carry Moisture Sensitivity Level 1 (Unlimited), and maintain identical regulatory status. Both parts are active products from TE Connectivity Measurement Specialties.

Q: What parameters must remain identical for substitution to be valid?

A: Substitution validity requires identical specifications across pressure type (Absolute), operating pressure range (4.35 PSI ~ 17.4 PSI), output type (I2C), output resolution (24 bit), accuracy (±0.007 PSI), supply voltage (1.5 V ~ 3.6 V), maximum pressure (145.04 PSI), operating temperature (-20°C ~ 85°C), mounting type (Surface Mount), package form (4-SMD Module), and termination style (SMD Tab). Packaging format variation is the only allowable difference.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same design and production environment. Packaging format differences do not affect board-level assembly, soldering processes, or functional performance.

Q: What inventory considerations apply when selecting between these equivalent parts?

A: The MS5837-02BA21 (Tape & Reel format) has 1979 pieces in stock, while the MS583702BA01-50 (Cut Tape & Digi-Reel® format) has 3300 pieces in stock. Selection should account for immediate availability requirements and procurement lead times.
