Key Features & Advantages

• Exact Teledyne RF323 Replacement: Guaranteed form, fit, and electrical function compatibility for seamless system integration without redesign.
• TO-5 Metal Can Reliability: Industry-standard hermetic package provides superior shielding and environmental protection compared to plastic PCB Signal Relays.
• Optimized for High-Density PCBs: Compact TO-5 footprint is ideal for space-constrained PCB Board Relay applications in drones and avionics.
• Military-Grade Construction: Built to withstand the harsh environments typical of Military Electromagnetic Relay applications, including vibration and temperature extremes.
• Long Operational Life: Engineered for a minimum of 100,000 cycles, ensuring reliability over extended service periods and reducing lifecycle costs.

Installation Procedure

1. Verify Compatibility: Confirm your system currently uses a Teledyne RF323 series relay.
2. Prepare PCB: Ensure the board is clean and the TO-5 footprint matches standard layouts.
3. Careful Handling: Use proper ESD precautions when handling the relay.
4. Precise Placement: Align the relay pins correctly with the PCB holes, noting the pin 1 indicator (typically a tab or marked pin).
5. Secure Soldering: Solder using recommended temperature profiles to ensure reliable connections without damaging the seal.
6. Functional Test: Test the circuit to verify proper switching operation before final assembly.

Application Scenarios

This relay is engineered for mission-critical applications where reliability is non-negotiable. It delivers significant value by providing a reliable, readily available alternative to the original RF323. Primary applications include: Drone flight controller and motor control boards, Aircraft engine FADEC (Full Authority Digital Engine Control) systems, Avionics instrumentation and communication equipment, Military ground vehicle electronic systems, and other high-reliability industrial controls where the TO-5 package is specified. It serves as a robust alternative in circuits where a standard DPDT 8Pin 27V Relay in a different package would not suffice.

Quality & Compliance

Manufactured in our ISO 9001 certified facility, the JPW-220M is produced under stringent quality controls. The production process includes 100% electrical testing, hermetic seal verification, and batch reliability testing to ensure performance meets or exceeds the original Teledyne RF323 specifications, a standard we maintain across our Military Metal Relay portfolio.

Customization Options

While the JPW-220M is designed for direct replacement, we offer OEM/ODM services for related projects. Custom coil voltages, specific screening tests (such as extended temperature range), or modified lead configurations can be arranged for volume requirements, similar to services for our Polarized Relay JH-2S.
