MICRF010BM RF Receiver ASK/OOK 300-440MHz Equivalent & Substitute Parts

Part Overview

The MICRF010BM is a surface-mount RF receiver module designed for ASK/OOK modulation in the 300MHz to 440MHz frequency band, commonly used in remote keyless entry (RKE) applications. The device operates at -104dBm sensitivity with a maximum data rate of 2kbps and requires a 4.75V to 5.5V supply voltage.

This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Direct substitutes must maintain identical electrical performance characteristics and mechanical compatibility with the 8-SOIC package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MICRF010BM is determined by strict equivalence across the following critical parameters:

• Frequency range: 300MHz ~ 440MHz
• Sensitivity: -104dBm
• Data rate capability: 2kbps maximum
• Modulation support: ASK and OOK
• Supply voltage: 4.75V ~ 5.5V
• Package: 8-SOIC surface mount
• Operating temperature range: -40°C ~ 85°C
• Receiving current: 2.9mA

The primary direct substitute is MICRF010YM, manufactured by Microchip Technology. This part maintains identical electrical specifications and mechanical compatibility. The MICRF010YM differs only in packaging format (Tube vs. Bulk) and regulatory compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

MICRF010YM is the direct functional equivalent to MICRF010BM. Both parts share identical electrical specifications, frequency response, sensitivity, data rate capability, and physical package dimensions. The primary distinction is regulatory compliance: MICRF010YM meets ROHS3 standards, while MICRF010BM does not.

For new designs or applications requiring RoHS compliance, MICRF010YM is the appropriate selection. For legacy systems or applications without RoHS requirements, either part provides equivalent performance. Both parts are manufactured by Microchip Technology and maintain the same pinout and footprint compatibility.

Packaging format differs between the two parts (Tube for MICRF010YM vs. Bulk for MICRF010BM), which may affect procurement quantities and handling procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can MICRF010YM be used as a direct replacement for MICRF010BM?
