CC2511F16RSPRG3 Equivalent & Substitute Parts

Part Overview

The CC2511F16RSPRG3 is an RF transceiver with integrated microcontroller designed for ISM band applications above 1GHz, specifically optimized for 2.4GHz operation. This device combines a complete RF front-end with an 8051-based microcontroller core, offering integrated functionality for wireless applications requiring minimal external components.

The CC2511F16RSPRG3 carries an Obsolete product status, making identification of compatible alternatives essential for ongoing design support, production continuity, and system maintenance. Active equivalent parts maintain identical electrical and mechanical specifications while offering current manufacturing availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CC2511F16RSPRG3 is determined by strict equivalence across the following critical parameters:

RF and Functional Specifications: Type (TxRx + MCU), RF Family/Standard (General ISM > 1GHz), Frequency (2.4GHz), Modulation support (2FSK, GFSK, MSK), Data Rate (500kBaud maximum), Power output (1dBm), and Sensitivity (-103dBm) must remain identical.

Memory and Interface Configuration: Memory size (16kB Flash, 2kB SRAM), Serial Interfaces (I2S, SPI, USART, USB), and GPIO count (19) must match exactly.

Electrical Characteristics: Supply voltage range (3V ~ 3.6V), receive current (14.7mA ~ 22.9mA), transmit current (15.5mA ~ 26mA), and operating temperature range (0°C ~ 85°C) must be maintained.

Physical and Environmental Compliance: Package type (36-VFQFN Exposed Pad), supplier device package (36-VQFN 6x6), RoHS3 compliance, and MSL rating (3, 168 Hours) must be preserved.

The CC2511F16RSPR represents a direct functional equivalent, differing only in packaging format (Tape & Reel versus individual packaging) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The CC2511F16RSPR is the direct equivalent for the obsolete CC2511F16RSPRG3. Both devices maintain identical electrical specifications, RF performance characteristics, memory configuration, and interface capabilities. The primary distinction is product lifecycle status: CC2511F16RSPR carries Active status with current manufacturing support, while CC2511F16RSPRG3 is classified as Obsolete.

Both parts maintain ROHS3 compliance and identical environmental ratings (MSL 3, 168 Hours), ensuring equivalent reliability and handling requirements. The packaging format difference (Tape & Reel for the active part versus individual packaging for the obsolete part) reflects standard distribution practices and does not affect electrical or mechanical compatibility.

For new designs or production continuity, CC2511F16RSPR is the appropriate selection. For existing inventory management or legacy system support, CC2511F16RSPRG3 remains functionally equivalent where available stock permits.

Frequently Asked Questions (FAQ)

Q: Can CC2511F16RSPR be used as a direct replacement for CC2511F16RSPRG3?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitute part carries Active product status, ensuring ongoing manufacturing availability and supply chain continuity.

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status (Obsolete versus Active) and packaging format (individual packaging versus Tape & Reel). All electrical, RF, memory, interface, and environmental specifications are identical.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. Both parts use the identical 36-VQFN (6x6) package with exposed pad. PCB footprints, solder pad layouts, and thermal management considerations remain unchanged.

Q: Do both parts require the same handling and storage procedures?

A: Yes. Both parts carry MSL rating 3 (168 Hours), requiring identical moisture control, storage temperature, and handling protocols during assembly and deployment.

Q: Which part should be specified for new production?

A: CC2511F16RSPR should be specified for new designs and ongoing production due to its Active status and assured supply availability. CC2511F16RSPRG3 is suitable only where existing inventory is available and product lifecycle discontinuation is acceptable.
