Coto Technology 9814-05-10 Relay RF SPST-NO 250MA 5V

Part Overview

The Coto Technology 9814-05-10 is a non-latching relay with SPST-NO (Single Pole Single Throw - Normally Open) contact form, rated for 250 mA switching current at 5VDC coil voltage. This relay is classified as Obsolete and requires identification of active equivalent alternatives for ongoing applications. The 9814 series represents a surface-mount, magnetically-shielded RF relay design suitable for applications requiring low-power control switching with fast response characteristics.

Key Parameters

Substitute Part Grouping Explanation

The Coto Technology 9814-05-00 serves as a direct functional substitute for the 9814-05-10. Substitution is based on the following electrical and mechanical parameters that must remain equivalent:

• Contact Form and Rating: Both maintain SPST-NO (1 Form A) configuration with 250 mA contact rating
• Coil Voltage and Current: Both operate at 5VDC with 33.3 mA coil current and 150 Ohms coil resistance
• Switching Characteristics: Both feature identical must-operate voltage (3.8 VDC), must-release voltage (0.4 VDC), operate time (0.25 ms), and release time (0.05 ms)
• Electrical Limits: Both support 100VAC and 100VDC maximum switching voltage
• Environmental Specifications: Both operate across -20°C to 85°C temperature range with MSL 2 rating
• Physical Configuration: Both are surface-mount devices with magnetic shielding

The primary difference between the parts lies in termination style (axial versus gull wing) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The 9814-05-00 is the recommended replacement for the obsolete 9814-05-10. Both relays maintain identical electrical performance across all functional parameters, including coil characteristics, contact switching ratings, timing specifications, and environmental operating ranges.

The 9814-05-00 provides the advantage of Active product status, ensuring ongoing availability and manufacturing support. The part also carries ROHS3 compliance, representing the most current regulatory standard, compared to the base RoHS compliance of the 9814-05-10.

Design consideration: The substitution requires accommodation of the termination style difference. The 9814-05-10 features axial termination, while the 9814-05-00 uses gull wing termination. PCB footprint and lead configuration must be evaluated against the target application's physical layout requirements.

Frequently Asked Questions (FAQ)

Q: Are the electrical specifications identical between 9814-05-10 and 9814-05-00? A: Yes. Both relays share identical coil voltage (5VDC), coil current (33.3 mA), contact rating (250 mA), switching voltage limits (100VAC/100VDC max), timing specifications (0.25 ms operate, 0.05 ms release), and operating temperature range (-20°C to 85°C).

Q: What is the primary difference between these two parts? A: The primary differences are termination style (axial vs. gull wing) and product status (obsolete vs. active). The 9814-05-00 also carries ROHS3 compliance while the 9814-05-10 carries base RoHS compliance.

Q: Can I use the 9814-05-00 to replace the 9814-05-10 in an existing design? A: Direct substitution requires PCB footprint compatibility. The gull wing termination of the 9814-05-00 differs from the axial termination of the 9814-05-10, necessitating pad layout modifications if the original design was optimized for the 9814-05-10 footprint.

Q: What is the coil resistance of these relays? A: Both relays have a coil resistance of 150 Ohms at 5VDC.

Q: Do both parts meet current regulatory compliance standards? A: The 9814-05-00 meets ROHS3 compliance and is an active product. The 9814-05-10 is obsolete and carries base RoHS compliance. For new designs, the 9814-05-00 is the appropriate choice.
