NI 783816-01 – Original NI Spare Part for Maintaining Modular Test & Control Systems

The NI 783816-01 is an original National Instruments replacement assembly, typically used to service or refurbish NI modular platforms (PXI, CompactRIO, or CompactDAQ families depending on BOM mapping). From my experience, teams keep this part on the shelf to shorten repair cycles and avoid unnecessary full-module swaps. You might notice that it installs as a drop-in component within the designated NI host assembly, preserving performance without changing system behavior.

One thing I appreciate is the traceable NI part number format—maintenance leads can quickly verify compatibility against their chassis/controller serials and service notes. A customer in an automotive test lab told me they swapped this part during scheduled downtime and were back to running sequences in under an hour, no revalidation needed beyond their standard functional check.

Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock items; no more than one month at the latest
• Payment method: 50% advance payment, full payment for delivery
• Express delivery: FedEx, UPS, DHL
• Pre-ship testing and visual inspection on request (helps reduce DOA risk)

Key Features

• Genuine NI spare part – Sourced to the NI 783816-01 part number for traceability and like-for-like fit.
• Drop-in replacement – Designed to install in the intended NI module or chassis position without mechanical changes.
• Backplane-powered – In most cases, no external power lines; inherits power from the host system.
• Service-friendly packaging – ESD-safe handling and labeling simplify maintenance workflows.
• Lifecycle support – Suitable for sustaining mature test stands where consistency matters more than redesign.
• Technical verification support – We can help validate the P/N against your NI BOM or service bulletin before purchase.

Technical Specifications

Application Fields

This part is typically used for sustaining NI-based systems in:

• Production ATE racks where uptime targets are strict and requalification is costly
• Aerospace and defense validation stands running long-duration sequences
• Automotive HIL benches and end-of-line testers needing consistent behavior
• Energy and research labs with standardized PXI/cRIO builds

Advantages & Value

• Reliability – Genuine NI assemblies tend to preserve calibration integrity and thermal characteristics of the original module.
• Compatibility – Like-for-like fit minimizes firmware or driver changes, reducing retest time.
• Cost control – In many cases, replacing the sub-assembly is more economical than swapping the entire device.
• Technical support – We help check P/N against your NI serial/build sheet before shipment.

Installation & Maintenance

• Install in an ESD-safe workspace; use a grounded wrist strap and anti-static mat.
• Follow the NI service/repair guide for your specific chassis or controller; torque and connector seating matter.
• Power down and disconnect mains before any panel or backplane access.
• Keep the cabinet ventilated; dust removal with dry air (low pressure) typically helps thermal stability.
• If applicable, document firmware/FPGA versions before/after replacement; some teams snapshot configuration to speed rollback.
• Routine checks every 6–12 months: visual inspection, connector integrity, and a quick functional self-test.

Quality & Certifications

NI assemblies are commonly produced under rigorous quality systems and are usually compliant with CE and RoHS requirements for the associated finished products. Many host NI systems carry UL/CE marks; this replacement part is intended to maintain that compliance when installed as specified. Manufacturer’s standard warranty applies; we extend a 365-day warranty on supply.
