Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MICRF009BM is determined by strict alignment with the following electrical and mechanical parameters:

• Frequency range: 300MHz ~ 440MHz
• Sensitivity: -102dBm
• Data rate capability: 2kbps maximum
• Modulation support: ASK and OOK
• Supply voltage: 4.75V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 16-SOIC form factor
• Mounting: Surface mount configuration
• Receiving current: 2.9mA

The MICRF009YM is a direct substitute manufactured by Microchip Technology, sharing identical electrical specifications and package configuration. Additional cross-reference parts (ATA8515-GHQW, MICRF219AAYQS, ATA8510-GHQW, MICRF220AYQS, MICRF230YQS) are listed as extended alternatives from the MICRF009YM substitution chain and require individual parameter verification against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The MICRF009YM is the primary direct substitute for the MICRF009BM. Both components share identical electrical performance specifications and mechanical packaging. The MICRF009YM offers improved regulatory compliance with ROHS3 certification, whereas the MICRF009BM is RoHS non-compliant. Both components maintain REACH Unaffected status and EAR99 export classification.

Selection between these parts should be based on regulatory requirements for the end application. If RoHS3 compliance is mandated, the MICRF009YM is the appropriate choice. If legacy RoHS non-compliant designs require exact specification matching, the MICRF009BM remains functionally equivalent where available.

Extended alternatives listed in the MICRF009YM substitution chain require detailed cross-reference verification against specific application parameters before implementation.

Frequently Asked Questions (FAQ)

Q: Can MICRF009YM be used as a direct replacement for MICRF009BM in existing designs?

A: Yes. The MICRF009YM is electrically and mechanically identical to the MICRF009BM. Both components operate at 300MHz ~ 440MHz with -102dBm sensitivity, 2kbps maximum data rate, and identical supply voltage and temperature ranges. The 16-SOIC package footprint is identical, requiring no PCB layout modifications.

Q: What is the primary difference between MICRF009BM and MICRF009YM?

A: The primary difference is regulatory compliance. MICRF009YM is ROHS3 compliant, while MICRF009BM is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are the extended alternatives (ATA8515-GHQW, MICRF219AAYQS, etc.) direct substitutes?

A: The extended alternatives are listed as cross-references from the MICRF009YM substitution chain. These parts require individual parameter verification to confirm compatibility with specific application requirements before selection.

Q: Does package compatibility require any design changes?

A: No. Both MICRF009BM and MICRF009YM use the 16-SOIC (0.154", 3.90mm Width) package. PCB footprints and land patterns are identical, requiring no layout modifications.

Q: What applications are these components designed for?

A: These RF receivers are designed for remote keyless entry (RKE) applications utilizing ASK and OOK modulation in the 300MHz to 440MHz frequency band.
