Substitute Part Grouping Explanation

Substitution of the CC1111F32RSPRG3 is based on strict electrical and mechanical parameter matching within the CC1111F product family. The substitute part CC1111F32RSPR maintains identical core specifications across all critical parameters:

• RF transceiver type and functionality (TxRx + MCU)
• Frequency band coverage (300MHz ~ 348MHz, 391MHz ~ 464MHz, 782MHz ~ 928MHz)
• Modulation support (2FSK, ASK, GFSK, MSK, OOK)
• Data rate capability (500kBaud maximum)
• RF performance metrics (10dBm output, -112dBm sensitivity)
• Memory configuration (32kB Flash, 4kB SRAM)
• Serial interface set (I2S, USART, USB)
• GPIO count (19 pins)
• Power supply range (3V ~ 3.6V)
• Current consumption specifications
• Operating temperature range (0°C ~ 85°C)
• Physical package (36-VFQFN Exposed Pad, 6x6mm)
• Compliance certifications (ROHS3, REACH Unaffected)

The primary difference is packaging format: the main part uses Digi-Reel® packaging, while the substitute uses Cut Tape (CT) & Digi-Reel® packaging. Both are surface mount variants with identical electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The CC1111F32RSPR is the direct functional equivalent of the CC1111F32RSPRG3. Selection of the substitute part is supported by:

• Identical electrical specifications across all RF, memory, interface, and power parameters
• Matching physical package dimensions and pin configuration (36-VFQFN, 6x6mm)
• Equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Active product status of the substitute part, ensuring ongoing availability and manufacturing support
• Obsolete status of the main part, necessitating transition to an active equivalent

The substitute part is suitable for direct replacement in applications currently using the CC1111F32RSPRG3, with no circuit redesign required.

Frequently Asked Questions (FAQ)

Q: Can CC1111F32RSPR be used as a direct replacement for CC1111F32RSPRG3?

A: Yes. Both parts are identical in electrical performance, RF specifications, memory configuration, interface capabilities, and physical package. The substitute part is the active equivalent.

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

A: The primary difference is packaging format. CC1111F32RSPRG3 uses Digi-Reel® packaging, while CC1111F32RSPR uses Cut Tape (CT) & Digi-Reel® packaging. Electrical and functional specifications are identical.

Q: Why is the main part listed as Obsolete?

A: The CC1111F32RSPRG3 has been discontinued by Texas Instruments. The CC1111F32RSPR remains in active production and is the recommended equivalent for new designs and ongoing procurement.

Q: Are there any compatibility concerns with the 36-VFQFN package?

A: No. Both parts use the identical 36-VFQFN Exposed Pad package in 6x6mm form factor. PCB footprints, solder reflow profiles, and handling requirements are the same.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, with identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours).

Q: What is the frequency coverage of these parts?

A: Both parts operate across three ISM frequency bands: 300MHz ~ 348MHz, 391MHz ~ 464MHz, and 782MHz ~ 928MHz, with support for 2FSK, ASK, GFSK, MSK, and OOK modulation.
