Amphenol Wilcoxon Sensing Technologies 780A Accelerometer Equivalent & Substitute Parts

Part Overview

The Amphenol Wilcoxon Sensing Technologies 780A is an active accelerometer sensor designed for single-axis motion measurement applications. This X-axis accelerometer operates within a ±80g acceleration range and delivers analog voltage output across a bandwidth of 0.5Hz to 14kHz. The 780A maintains Active product status and is RoHS Compliant, making it suitable for industrial and aerospace applications requiring reliable vibration and acceleration monitoring.

Substitute parts become necessary when addressing inventory constraints, supply chain disruptions, or when equivalent performance specifications are required from alternative stock sources. The 786A represents a parametrically equivalent alternative that maintains identical electrical and mechanical characteristics while offering independent availability.

Substitute Part Grouping Explanation

The 786A qualifies as a parametric equivalent to the 780A based on strict alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Acceleration Measurement Capability: Both the 780A and 786A measure acceleration across an identical ±80g range on the X axis, ensuring equivalent sensor response to dynamic motion inputs.

Signal Conditioning and Output: Both sensors deliver 100 mV/g sensitivity with analog voltage output, maintaining signal compatibility with existing measurement and data acquisition systems.

Frequency Response: The 0.5Hz to 14kHz bandwidth specification is identical across both models, preserving system frequency response characteristics and filtering behavior.

Power Supply Requirements: Both sensors operate within the 18V to 30V supply voltage range, allowing direct integration into existing power distribution architectures without modification.

Environmental Operating Envelope: Identical operating temperature range of -55°C to 120°C ensures both sensors function within the same thermal constraints and environmental conditions.

Physical Integration: Chassis Mount configuration and Module package type are consistent across both models, supporting direct mechanical substitution without redesign of mounting interfaces.

Regulatory Compliance: Both sensors maintain RoHS Compliant status and MSL 1 (Unlimited) moisture sensitivity rating, satisfying identical regulatory and reliability requirements.

Engineering Selection Recommendations

Primary Selection - 780A: The 780A is the primary component specification and should be selected when available from inventory. Current stock of 1056 units supports immediate deployment in production environments. Active product status confirms ongoing manufacturer support and supply chain stability.

Substitute Selection - 786A: The 786A serves as a direct parametric equivalent when 780A availability is constrained. With 661 units in current inventory, the 786A provides independent supply chain access while maintaining identical electrical and mechanical performance. Both sensors carry Active product status and RoHS Compliance certification, ensuring equivalent regulatory acceptance and long-term support.

Interchangeability Basis: Selection between 780A and 786A is determined solely by inventory availability and supply chain logistics. No performance differentiation exists between the two models based on provided specifications. Both sensors integrate identically into existing circuit designs, measurement systems, and mechanical assemblies.
