Why obsolete integrated circuits & semiconductors? Why not?
If you have circuit boards to buy or repair, or if an obsolete component is needed, you now have a choice. You can:
- design a new circuit board with replacement chips (if available);
- draw up new specification sheets and get customer or military approval; or
- Accept the fact that this is an expensive and time consuming project and replace the part with the original one that is tried and true.
The trick is finding a part that is no longer made by the manufacturer. This is where Danrock comes in! We specialize and finding obsolete and hard-to-find integrated circuits and semiconductors. Danrock offers competitive pricing on these parts and will have them delivered right to your door.
What about used or reconditioned IC's?
All semiconductors have extremely long life spans. A very high percentage of chips that drop dead while in use fail during the first couple hundred hours. It is called "infant mortality". If a semiconductor makes it through infancy, it's presence adds to the overall expected reliability.
The military subjects semiconductors to costly burn-in tests to increase reliability. Chips may go bad during the burn-in process, but if they survive the odds for later failure are greatly reduced.
Parts that have seen service are, in essence, already burned in and thus tested more rigorously then a new commercial part. Thus, recycling parts can reduce cost, improve reliability and help preserve the environment.
What type of payments does Danrock accept?
Danrock accepts direct payment via Master Charge & Visa only. After purchase order has been received, Danrock will contact you by phone within 48 hours for credit card information.
Danrock can accept all major credit cards if paying via PayPal. You will receive an e-mail invoice within 48 hours after purchase order has been received.

Does Danrock have a minimum order?
We do not have a minimum order, however, an additional fee of $5.00 will be charged to orders totaling less than $100.00.
How will my parts be shipped, and what are the shipping costs?
Unless otherwise indicated, all parts will be shipped via UPS according to the following shipping chart:
| Weight | Ground | 3 Day Air | 2 Day Air | Next Day Air |
