Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BGA3018,115 are evaluated based on the following critical parameters: package compatibility (TO-243AA / SOT-89 form factor), surface-mount technology, supply voltage range overlap, and frequency coverage that encompasses or exceeds the CATV band (5MHz ~ 1GHz).

The substitute parts are grouped into two categories based on frequency and power characteristics:

Group 1 (HMC311 Series): General-purpose RF amplifiers with extended frequency coverage (0Hz ~ 6GHz) but reduced output power (13dBm P1dB) and gain (14.5dB) compared to the BGA3018,115. These parts operate at 5V supply voltage and are suitable for applications where frequency flexibility is prioritized over output power.

Group 2 (HMC480 Series): General-purpose RF amplifiers with frequency coverage (0Hz ~ 5GHz) that encompasses the CATV band, higher output power (20dBm P1dB), and gain (19dB) exceeding the BGA3018,115 specifications. These parts require 6V ~ 8V supply voltage and deliver superior performance metrics within the target frequency range.

All substitute parts maintain TO-243AA / SOT-89 package compatibility, surface-mount configuration, ROHS3 compliance, and EAR99 export classification.

Parameter Comparison

Engineering Selection Recommendations

For CATV-band applications requiring output power and gain matching: The HMC480ST89E and HMC480ST89ETR are the primary substitutes. Both parts deliver 20dBm P1dB and 19dB gain, exceeding the BGA3018,115 specifications. The HMC480ST89ETR (Hittite) offers significantly higher inventory availability (61,931 pcs) compared to HMC480ST89E (2,007 pcs). Both maintain ROHS3 compliance and operate within the 6V ~ 8V supply range, which overlaps with the BGA3018,115 voltage specification. Supply current increases to 82mA, requiring thermal and power budget verification.

For applications prioritizing frequency flexibility over output power: The HMC311ST89E and HMC311ST89ETR provide extended frequency coverage (0Hz ~ 6GHz) with reduced output power (13dBm P1dB) and gain (14.5dB). These parts operate at fixed 5V supply voltage and deliver comparable supply current (74mA). The HMC311ST89ETR (Hittite) provides substantially higher inventory (15,975 pcs) versus HMC311ST89E (1,310 pcs). Both maintain ROHS3 compliance where specified.

All substitute parts are in Active product status, ensuring long-term availability and supply chain stability compared to the BGA3018,115 Last Time Buy designation.

Frequently Asked Questions (FAQ)

Q: Can HMC311 parts directly replace BGA3018,115 in existing CATV designs?

A: HMC311 parts are package-compatible and operate within overlapping voltage ranges, but deliver reduced output power (13dBm vs. 18dBm) and gain (14.5dB vs. 18dB). Circuit performance will be degraded. Use only if application specifications permit lower output power and gain margins.

Q: What are the key differences between HMC480 and HMC311 substitutes?

A: HMC480 parts deliver higher output power (20dBm P1dB) and gain (19dB) with frequency coverage to 5GHz, requiring 6V ~ 8V supply. HMC311 parts provide extended frequency coverage to 6GHz with reduced power (13dBm P1dB) and gain (14.5dB) at fixed 5V supply. HMC480 is preferred for CATV-band applications requiring power performance.

Q: Are there packaging differences between substitute options?

A: All substitute parts use TO-243AA / SOT-89 surface-mount packaging, maintaining PCB layout compatibility with BGA3018,115. Packaging variants (Strip, Bulk) affect tape-and-reel configuration but not component form factor or pinout.

Q: Which substitute offers the best inventory availability?

A: HMC480ST89ETR (Hittite) provides the highest inventory at 61,931 pcs. HMC311ST89ETR (Hittite) offers 15,975 pcs. Both Hittite variants ensure supply continuity for production volumes.

Q: Do all substitutes maintain RoHS3 compliance?

A: HMC480ST89E and HMC311ST89E explicitly state ROHS3 compliance. HMC480ST89ETR and HMC311ST89ETR do not specify RoHS status in provided data. Verify RoHS certification with manufacturer documentation if compliance is required.

Q: What supply voltage considerations apply when switching substitutes?

A: BGA3018,115 operates at 5V ~ 8V. HMC311 parts require fixed 5V supply. HMC480 parts require 6V ~ 8V supply. Designs using 5V-only supplies cannot use HMC480 parts without voltage regulation modifications. Designs using 6V ~ 8V supplies can use HMC480 parts directly.
