EM260-RTY Equivalent & Substitute Parts

Part Overview

The EM260-RTY is an integrated RF transceiver with embedded microcontroller (MCU) designed for 802.15.4 Zigbee® 2.4GHz wireless applications. This component combines RF transmission and reception capabilities with an on-chip MCU in a 40-pin VFQFN surface mount package. The EM260-RTY is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EM260-RTY is determined by strict alignment of the following electrical and mechanical parameters:

• RF Family/Standard: 802.15.4
• Protocol: Zigbee®
• Frequency: 2.4GHz
• Type: TxRx + MCU
• Package / Case: 40-VFQFN Exposed Pad
• Serial Interfaces: SPI, UART
• Voltage Supply Range: 2.1V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C

The EM260-RTR qualifies as a direct substitute based on identical electrical specifications and package configuration. Both parts share the same RF transceiver architecture, protocol support, and physical form factor, differing only in packaging format (Cut Tape vs. standard packaging) and minor compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The EM260-RTR is the qualified substitute for the EM260-RTY. Both components are obsolete products from Silicon Labs with identical electrical and RF performance characteristics. The EM260-RTR offers improved compliance status with RoHS certification and a lower Moisture Sensitivity Level (MSL 2 vs. MSL 3), providing better long-term storage and handling characteristics. Inventory availability of the EM260-RTR (16,385 units) exceeds that of the EM260-RTY (3,845 units), supporting sustained procurement for legacy system maintenance and repair operations.

Frequently Asked Questions (FAQ)

Q: Can the EM260-RTR be used as a direct replacement for the EM260-RTY in existing designs?

A: Yes. Both parts share identical electrical specifications, RF performance parameters, serial interfaces, and package configuration. The primary difference is packaging format and compliance certifications. No circuit modifications are required.

Q: What is the difference between the EM260-RTY and EM260-RTR packaging?

A: The EM260-RTY is supplied in standard packaging, while the EM260-RTR is supplied in Cut Tape (CT) format. Both use the same 40-VFQFN Exposed Pad physical package.

Q: Why does the EM260-RTR have a lower Moisture Sensitivity Level (MSL)?

A: MSL 2 (1 Year) indicates superior moisture resistance compared to MSL 3 (168 Hours). The EM260-RTR maintains functionality under higher humidity conditions for extended periods, reducing risk during storage and assembly operations.

Q: Are there any functional differences between these parts?

A: No. Both parts implement identical 802.15.4 Zigbee® 2.4GHz RF transceiver functionality with embedded MCU, identical power output, sensitivity, current consumption, and operating temperature range.

Q: What compliance certifications apply to each part?

A: The EM260-RTR is RoHS Compliant. Both parts are REACH Unaffected and share identical ECCN and HTSUS classifications for export and tariff purposes.
