"Cross-reference" here means an engineering/procurement comparison aid — not a claim that every listed pair is mechanically, electrically or functionally interchangeable. Each guide below pulls together the manufacturer's own compatibility tables and lineup data, with the checks worth confirming before you order.
Component families like sensors and relays are often ordered off a shortened model name or a "same size" assumption. These guides go one level deeper: official replacement tables where the manufacturer publishes them, model-to-socket or NPN/PNP lineup counterparts where they don't, and the specific electrical/mechanical checks that decide whether a match actually works in your machine. A cross-reference is a starting point for verification, not a guarantee of interchangeability.
These guides cover the cross-reference requests we see most often. If your component isn't listed yet, send us the full model number or a nameplate photo — we'll tell you what the manufacturer's own replacement data says and what's worth verifying before you order, the same way each guide above does.
Tell us the brand, model and application — get an honest cross-reference assessment within 48 hours. Official replacement data, what changes, and what's worth checking before you order.
