CC1175RHMT RF Transmitter ISM Band Equivalent & Substitute Parts

Part Overview

The CC1175RHMT is an RF transmitter IC designed for ISM and SRD band applications, operating across 164–192 MHz, 274–320 MHz, 410–480 MHz, and 820–960 MHz frequency ranges. This device delivers 16 dBm output power at 200 kbps data rate with a supply voltage range of 2V to 3.6V, housed in a 32-VFQFN surface mount package with exposed pad.

The CC1175RHMT carries an Obsolete product status. Locating equivalent substitute parts is necessary for ongoing production support, design continuity, and inventory management when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC1175RHMT is determined by strict alignment of the following electrical and mechanical parameters:

Frequency coverage must match all four ISM/SRD bands: 164–192 MHz, 274–320 MHz, 410–480 MHz, and 820–960 MHz. Data rate capability must support 200 kbps maximum. Output power must be 16 dBm. Supply voltage range must encompass 2V–3.6V operation. Current consumption during transmission must not exceed 54 mA. Operating temperature range must span –40°C to +85°C. Package configuration must be 32-VFQFN with exposed pad in surface mount form factor. Data interface and antenna connection must both be PCB surface mount types. Compliance certifications (RoHS3, MSL 3) must be maintained.

The CC1175RHBR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format: CC1175RHBR is supplied in Tape & Reel format, whereas CC1175RHMT uses standard packaging. Both devices share the same base product number (CC1175) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The CC1175RHBR is a direct functional equivalent to the CC1175RHMT. Both devices are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters: frequency coverage, data rate, output power, supply voltage, current consumption, operating temperature range, and package configuration.

The CC1175RHBR holds Active product status, whereas the CC1175RHMT is classified as Obsolete. This status difference makes CC1175RHBR the preferred selection for new designs and ongoing production requirements. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and regulatory compliance.

The sole practical distinction between these parts is packaging format: CC1175RHBR is supplied in Tape & Reel format, which is standard for high-volume manufacturing and automated assembly processes. This packaging difference does not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can CC1175RHBR be used as a direct replacement for CC1175RHMT in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters. The CC1175RHBR operates at identical frequency ranges, output power, data rate, supply voltage, and current consumption. PCB layout and component placement require no modification.

Q: What is the difference between CC1175RHMT and CC1175RHBR?

A: The primary difference is packaging format. CC1175RHMT uses standard packaging, while CC1175RHBR is supplied in Tape & Reel (TR) format. Additionally, CC1175RHBR carries Active product status, whereas CC1175RHMT is Obsolete. The die and electrical specifications are identical.

Q: Why is CC1175RHMT listed as Obsolete?

A: Obsolete status indicates the part is no longer in active production. CC1175RHBR, the Active variant, is the recommended source for current and future procurement.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and MSL 3 (168 Hours) moisture sensitivity ratings. Environmental and regulatory compliance is equivalent.

Q: Does Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a delivery and handling format used for automated assembly. It does not alter electrical performance, frequency response, output power, or any functional characteristic of the device.

Q: Can CC1175RHBR handle the same frequency bands as CC1175RHMT?

A: Yes. Both parts support identical frequency coverage: 164–192 MHz, 274–320 MHz, 410–480 MHz, and 820–960 MHz for ISM and SRD applications.

Q: What is the current availability of these parts?

A: CC1175RHBR is listed as Active with 35,200 units in stock. CC1175RHMT is Obsolete with 3,160 units remaining in inventory. For new procurement, CC1175RHBR is the appropriate selection.
