CC1020RUZ Equivalent & Substitute Parts

Part Overview

The CC1020RUZ is a radio frequency transceiver integrated circuit designed for ISM band applications below 1GHz, specifically covering 402MHz to 470MHz and 804MHz to 960MHz frequency ranges. This device operates as a TxRx Only transceiver with FSK, GFSK, and OOK modulation support. The CC1020RUZ is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CC1020RUZ is determined by strict equivalence across the following critical parameters:

• RF transceiver type classification (TxRx Only)
• ISM band frequency coverage (402MHz ~ 470MHz, 804MHz ~ 960MHz)
• Modulation support (FSK, GFSK, OOK)
• Serial interface compatibility (SPI, UART)
• Package form factor (32-VQFN Exposed Pad)
• Electrical specifications (supply voltage, output power, sensitivity, data rate)
• Environmental and compliance ratings (operating temperature, RoHS3, MSL)

The CC1020RSST meets all these criteria as an active product variant of the same base product number (CC1020) with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CC1020RSST is the direct active equivalent for the obsolete CC1020RUZ. Both parts share identical electrical performance, frequency coverage, modulation capabilities, and package specifications. The primary distinction is product status: CC1020RUZ is obsolete while CC1020RSST is active.

For new designs and production continuity, CC1020RSST is the appropriate selection. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with current manufacturing and environmental standards. The packaging difference (bulk versus Tape & Reel) reflects standard distribution practices and does not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can CC1020RSST directly replace CC1020RUZ in existing designs?

A: Yes. Both parts are functionally identical across all electrical and mechanical parameters. The CC1020RSST is the active production equivalent of the obsolete CC1020RUZ.

Q: What is the difference between CC1020RUZ and CC1020RSST?

A: The parts are electrically and mechanically identical. The primary difference is product status (obsolete versus active) and packaging format (bulk versus Tape & Reel). Both share the same base product number (CC1020) and specifications.

Q: Are there any compatibility concerns with the 32-VQFN package?

A: No. Both parts use the identical 32-VQFN Exposed Pad package with the same pinout, footprint, and thermal characteristics. PCB layouts and assembly processes require no modification.

Q: Do both parts support the same frequency bands and modulation types?

A: Yes. Both CC1020RUZ and CC1020RSST support 402MHz to 470MHz and 804MHz to 960MHz frequency ranges with FSK, GFSK, and OOK modulation.

Q: Are the supply voltage and current specifications identical?

A: Yes. Both parts operate at 2.3V to 3.6V supply voltage with identical receive current (19.9mA) and transmit current (12.3mA to 27.1mA) specifications.

Q: What compliance certifications apply to both parts?

A: Both CC1020RUZ and CC1020RSST are ROHS3 compliant with MSL rating of 3 (168 Hours). REACH status is unaffected for both parts.
