The JRC-110MA Military Metal Relay represents precision-engineered replacement technology specifically developed as a direct form-fit-function substitute for the renowned Teledyne 411D series relays. Engineered with TO-5 package compatibility and 27V DC operation, this Military Metal Sealing Relay delivers authentic performance replacement for legacy military, aerospace, and high-reliability industrial systems where original Teledyne components are obsolete or unavailable, while maintaining the exact mechanical and electrical characteristics required for seamless system integration.

The JRC-110MA is engineered as a direct drop-in replacement for Teledyne 411D series relays, maintaining exact TO-5 package dimensions, pin configuration, and electrical characteristics. This authentic replacement capability provides a reliable solution for systems where original Teledyne components are no longer available, surpassing the compatibility of generic Aviation DC Relays or standard PCB Board Relays.
Featuring industry-standard TO-5 packaging, this relay maintains compatibility with existing PCB layouts, mounting hardware, and thermal management systems designed for the original 411D series. This standardization ensures seamless integration without circuit redesign, unlike many modern Automotive Relays or specialized Flash Relays with different form factors.
While maintaining exact mechanical and electrical compatibility, the JRC-110MA incorporates modern manufacturing techniques and material improvements that enhance reliability beyond the original 411D design. These improvements include advanced contact materials for reduced wear and enhanced coil insulation for longer service life.
Our specialized knowledge in legacy component replacement, developed through extensive work with Military Electromagnetic Relays and Sealed Magnetic Latching Relays, ensures that each JRC-110MA provides authentic performance while incorporating modern reliability enhancements unavailable in the original design.
The JRC-110MA is manufactured to meet or exceed original Teledyne 411D specifications:
YUMU Electronics maintains specialized expertise in legacy component replacement, applying rigorous quality controls developed through manufacturing Polarized Relay JH-2S, Industrial Power Relays, and other specialized military components.
Each JRC-110MA undergoes specialized manufacturing to ensure authentic replacement capability:
Yes, the JRC-110MA is engineered as a direct form-fit-function replacement with identical TO-5 package dimensions, pin configuration, electrical characteristics, and performance specifications, ensuring seamless integration without circuit modifications.
Each production batch undergoes comprehensive testing including dimensional verification, electrical parameter matching, environmental testing to original specifications, and functional testing in circuits designed for 411D relays to validate replacement compatibility.
While modern DPDT 8Pin 27V Relay designs offer different configurations and packages, the JRC-110MA specifically maintains the TO-5 package and electrical characteristics of the original Teledyne 411D series for legacy system compatibility where package standardization is critical.
We maintain production capability for legacy replacement components with typical lead times of 4-6 weeks. Priority production can be arranged for urgent system sustainment requirements.
