Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BLM8G0710S-30PBY is determined by the following critical parameters:

• Gain: 35dB (exact match required)
• Frequency Range: 957.5MHz operation capability (must fall within or encompass this frequency)
• Technology: LDMOS FET architecture
• Mounting Type: Surface Mount
• Package Compatibility: Physical and electrical compatibility with SOT-1211-3 footprint or equivalent LGA package

The substitute part B10H0710N40DX meets these criteria through matching gain specification (35dB), overlapping frequency range (700MHz ~ 1GHz encompasses 957.5MHz), identical LDMOS technology, surface mount configuration, and compatible LGA package format.

Parameter Comparison

Engineering Selection Recommendations

The B10H0710N40DX serves as an active substitute for the BLM8G0710S-30PBY based on the following factors:

• Product Status: B10H0710N40DX maintains Active status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.
• Compliance: BLM8G0710S-30PBY is ROHS3 Compliant; RoHS compliance status for B10H0710N40DX is not specified in available documentation.
• Frequency Coverage: The B10H0710N40DX frequency range of 700MHz ~ 1GHz fully encompasses the 957.5MHz operating point of the original design.
• Gain Specification: Both parts deliver identical 35dB gain, maintaining amplification performance.
• Package Transition: Migration from SOT-1211-3 (16-HSOPF) to 34-TLGA Exposed Pad requires PCB layout redesign and thermal management evaluation due to different package geometries and pin configurations.

Frequently Asked Questions (FAQ)

Q: Can B10H0710N40DX be used as a direct pin-for-pin replacement?

A: No. The BLM8G0710S-30PBY uses a 16-HSOPF package (SOT-1211-3), while the B10H0710N40DX uses a 34-LGA (12x8) package. Pin count, pinout, and physical dimensions differ, requiring PCB redesign.

Q: Are the gain specifications identical between these parts?

A: Yes. Both parts specify 35dB gain, ensuring equivalent amplification performance in RF applications.

Q: Does the frequency range difference affect compatibility?

A: The B10H0710N40DX frequency range of 700MHz ~ 1GHz encompasses the 957.5MHz operating frequency of the original part. The substitute is suitable for this application frequency.

Q: What is the impact of different supply voltage specifications?

A: The original part specifies 28V supply voltage, while the substitute specifies 48V rated voltage with 110V maximum. Circuit design modifications may be required to accommodate different voltage operating points.

Q: Is RoHS compliance maintained with the substitute part?

A: The original BLM8G0710S-30PBY is ROHS3 Compliant. RoHS compliance status for B10H0710N40DX is not specified in the provided documentation and must be verified with the manufacturer.

Q: What thermal considerations apply to the package change?

A: The 34-TLGA Exposed Pad package of the B10H0710N40DX provides different thermal characteristics compared to the 16-HSOPF package. Thermal analysis and PCB layout optimization are necessary to ensure adequate heat dissipation.
