HSMP-4810-TR1G Equivalent & Substitute Parts

Part Overview

The HSMP-4810-TR1G is an RF PIN diode manufactured by Broadcom Limited, designed for high-frequency switching and attenuation applications. This single PIN diode operates at a peak reverse voltage of 100V with a maximum current rating of 1A in a compact SOT-23-3 surface-mount package. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMP-4810-TR1G is determined by the following electrical and mechanical parameters:

• Diode Type: Must be PIN - Single configuration
• Voltage Rating: Substitute must meet or exceed 100V peak reverse voltage
• Current Capacity: Substitute must support minimum 1A maximum current
• Frequency Performance: Capacitance and resistance characteristics must be compatible with RF switching applications
• Operating Temperature: Substitute must support the required thermal range
• Package Compatibility: Physical form factor must be compatible with circuit board layout constraints

The two identified substitutes, CLA4611-085LF and SMP1304-079LF, both satisfy these core electrical requirements while offering enhanced performance specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts exceed the electrical performance requirements of the HSMP-4810-TR1G and carry active product status with full manufacturing support.

CLA4611-085LF provides the highest voltage rating (180V) and current capacity (1.5A) with enhanced power dissipation capability (2W). This part is suitable for applications requiring margin above the original 100V specification. The 2-VDFN package requires PCB layout modification from the original SOT-23-3 footprint.

SMP1304-079LF maintains closer electrical characteristics to the original part, with 200V voltage rating and 2Ohm resistance at 100mA matching the original measurement conditions. The SC-79 package is a direct mechanical alternative to SOT-23-3 for many applications. This part carries ROHS3 compliance and active production status.

Both substitutes are REACH Unaffected and classified under ECCN EAR99, maintaining the same regulatory compliance profile as the original part.

Frequently Asked Questions (FAQ)

Q: Can CLA4611-085LF be used as a direct replacement for HSMP-4810-TR1G?

A: CLA4611-085LF meets all electrical substitution criteria with superior voltage and current ratings. However, the package change from SOT-23-3 to 2-VDFN Exposed Pad requires PCB layout modification and footprint redesign.

Q: What are the key differences between the two substitute options?

A: CLA4611-085LF offers higher power dissipation (2W vs. 250mW for SMP1304-079LF) and current capacity (1.5A). SMP1304-079LF provides a more conservative upgrade path with lower power rating and SC-79 package compatibility closer to the original SOT-23-3 form factor.

Q: Are package changes required for either substitute?

A: Yes. Both substitutes use different packages than the original SOT-23-3. CLA4611-085LF uses 2-VDFN Exposed Pad; SMP1304-079LF uses SC-79. Circuit board layout and footprint modifications are necessary for either option.

Q: Do the substitutes maintain the same operating temperature range?

A: CLA4611-085LF supports 175°C junction temperature, exceeding the original 150°C. SMP1304-079LF specifies -65°C to 150°C ambient temperature range, covering the original operating window.

Q: What is the substitution basis for these parts?

A: Both parts are PIN - Single diodes meeting or exceeding the 100V peak reverse voltage and 1A current requirements. Electrical characteristics including capacitance and resistance are compatible with RF switching applications at the specified frequency ranges.
