Product
What is MPN Radar?
MPN Radar is the public website for Chip Monitor, an electronic component stock monitoring service for purchasing and engineering teams. It tracks supplier availability by exact manufacturer part number (MPN), brings stock, price breaks, and lead times from connected suppliers such as DigiKey, Mouser, and Texas Instruments into one dated view, and alerts you when a monitored condition changes. Every result keeps its source and timestamp; a failed collection is shown as a failure, not as zero stock. Monitoring does not place an order unless a separate safeguarded ordering workflow is enabled.

FAQ
Answers to common monitoring questions.
Can I use it without being technical?
Yes. Add a part and set a stock condition; the platform checks supplier channels that are currently enabled and ready.
Which channels are supported?
Chip Monitor supports integrations for DigiKey, Mouser, Texas Instruments, Microchip, element14, Future Electronics, and Arrow. Channels available for monitoring depend on platform enablement, credentials, region, and quota; Verical offers arrive with the Arrow channel.
When will I receive an alert?
When stock meets a condition you set, we show the channel and timestamp with the change.
Will it place orders automatically?
Only on the Business plan. Monitoring alerts on stock changes; automatic ordering is a separate, safeguarded workflow.
How often is data updated?
Choose the monitoring interval that fits your work. Each observation shows its latest update time.
Is this an electronic component search engine?
It is an exact-part stock search and monitoring tool. Enter a known manufacturer part number to compare supplier availability and keep watching it; use a parametric search tool when you still need to choose the component itself.
