TE Connectivity 834-2000 Accelerometer Equivalent & Substitute Parts

Part Overview

The TE Connectivity Measurement Specialties 834-2000 is a triaxial IEPE accelerometer designed for motion sensing applications requiring ±2000g acceleration measurement across X, Y, and Z axes. This component operates at 2kHz bandwidth with 0.62 mV/g sensitivity and is packaged in a 5-SMD, No Lead surface mount configuration.

The 834-2000 is classified as an obsolete product. Identification of equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this accelerometer.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 834-2000 accelerometer is determined by the following critical parameters that must remain consistent or compatible:

Core Functional Parameters:

• Acceleration range of ±2000g
• Triaxial measurement capability (X, Y, Z axes)
• Analog output signal type
• Operating temperature range of -40°C ~ 125°C
• Supply voltage compatibility within 3V ~ 5.5V range
• Surface mount packaging technology

Compliance & Environmental Parameters:

• ROHS3 compliance status
• Moisture sensitivity level classification
• Supplier device package compatibility

The substitute part 830M1-2000 maintains the core acceleration measurement specification of ±2000g across three axes and operates within the same temperature and voltage ranges. Both components are manufactured by TE Connectivity Measurement Specialties and carry ROHS3 compliance certification. The primary differences lie in output type, bandwidth specification, package configuration, and product status.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 830M1-2000

The 830M1-2000 is the manufacturer-recommended substitute for the obsolete 834-2000. Both components share identical acceleration measurement specifications (±2000g triaxial), equivalent sensitivity values (0.62 mV/g versus 0.63 mV/g), and matching operating temperature ranges (-40°C ~ 125°C). Both devices maintain ROHS3 compliance and MSL 1 classification.

The 830M1-2000 is currently in active product status with 953 units available in inventory, providing supply chain continuity for applications requiring ±2000g triaxial acceleration measurement.

Key Differences Requiring Design Consideration:

The 830M1-2000 differs from the 834-2000 in three areas:

1. Output Signal Type: The 834-2000 provides IEPE (Integrated Electronics Piezoelectric) output, while the 830M1-2000 provides standard Analog Voltage output. Applications utilizing IEPE signal conditioning will require interface modification.

2. Bandwidth Specification: The 834-2000 operates at 2kHz bandwidth, while the 830M1-2000 provides extended bandwidth of 2Hz ~ 15kHz. This expanded frequency response is compatible with applications requiring the original 2kHz specification.

3. Package Configuration: The 834-2000 uses 5-SMD, No Lead packaging, while the 830M1-2000 uses 12-LCC packaging. PCB layout and footprint modifications are required.

4. Supply Voltage Range: The 834-2000 accepts 3V ~ 5.5V, while the 830M1-2000 requires 3.3V ~ 5.5V. Applications operating at 3V supply voltage require verification of compatibility.

The 830M1-2000 includes an integrated temperature sensor feature not present in the 834-2000.

Frequently Asked Questions (FAQ)

Q: Can the 830M1-2000 directly replace the 834-2000 without circuit modifications?

A: Direct replacement requires evaluation of three factors: (1) signal conditioning compatibility with Analog Voltage output versus IEPE output, (2) PCB footprint compatibility between 5-SMD and 12-LCC packages, and (3) supply voltage compatibility if the application operates at 3V. The acceleration measurement specifications are equivalent.

Q: What is the sensitivity difference between these two accelerometers?

A: The 834-2000 provides 0.62 mV/g sensitivity, while the 830M1-2000 provides 0.63 mV/g sensitivity. This 1.6% difference is within typical measurement tolerance for most applications and does not prevent substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the 834-2000 and 830M1-2000 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the bandwidth difference and does it affect compatibility?

A: The 834-2000 operates at 2kHz bandwidth, while the 830M1-2000 provides 2Hz ~ 15kHz bandwidth. The substitute part's extended bandwidth encompasses the original specification and is compatible with applications designed for 2kHz operation.

Q: Why is the 834-2000 listed as obsolete?

A: The 834-2000 has been discontinued by TE Connectivity Measurement Specialties. The 830M1-2000 is the active product replacement offering equivalent acceleration measurement capability with enhanced bandwidth and integrated temperature sensing.

Q: What packaging considerations apply to substitution?

A: The 834-2000 uses 5-SMD, No Lead surface mount packaging, while the 830M1-2000 uses 12-LCC surface mount packaging. Both are surface mount technologies, but PCB footprint, land pattern, and assembly process modifications are required.

Q: Is the integrated temperature sensor in the 830M1-2000 a required feature?

A: The temperature sensor is an additional feature in the 830M1-2000 not present in the 834-2000. Applications not requiring temperature measurement are unaffected by this addition.
