HSMP-4810-TR2G Equivalent & Substitute Parts

Part Overview

The HSMP-4810-TR2G is an RF PIN diode manufactured by Broadcom Limited, designed for RF switching and attenuation applications. This single PIN diode operates at a peak reverse voltage of 100V with a maximum current rating of 1A, housed in a SOT-23-3 package. The product is currently obsolete, making identification of functionally equivalent substitute components essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMP-4810-TR2G is determined by the following electrical and mechanical criteria:

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

The identified substitutes (CLA4611-085LF and SMP1304-079LF) satisfy these criteria with enhanced electrical specifications, providing higher voltage ratings and improved RF characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Skyworks Solutions Inc. and maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete HSMP-4810-TR2G.

CLA4611-085LF provides enhanced electrical performance with 180V peak reverse voltage and 1.5A maximum current, exceeding the original specifications. This part operates at a maximum junction temperature of 175°C and is ROHS3 compliant. The 2-VDFN package requires PCB layout modification from the original SOT-23-3 footprint.

SMP1304-079LF offers the highest voltage rating at 200V peak reverse voltage with improved RF characteristics (0.3pF capacitance and 2Ohm resistance). This part is ROHS3 compliant and operates across an extended temperature range (-65°C to 150°C). The SC-79 package is a smaller form factor than SOT-23-3, requiring PCB redesign.

Both substitutes meet or exceed the electrical requirements of the original part and carry equivalent moisture sensitivity ratings and REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can CLA4611-085LF or SMP1304-079LF be used as direct drop-in replacements for HSMP-4810-TR2G?

A: Both parts are electrically compatible as PIN diode substitutes, but package differences require PCB layout modifications. HSMP-4810-TR2G uses SOT-23-3, while CLA4611-085LF uses 2-VDFN and SMP1304-079LF uses SC-79 packaging.

Q: What are the key electrical advantages of the substitute parts?

A: CLA4611-085LF and SMP1304-079LF both exceed the original 100V voltage rating (180V and 200V respectively) and provide lower capacitance values, improving RF performance at higher frequencies. SMP1304-079LF offers the lowest capacitance at 0.3pF.

Q: Are the substitute parts RoHS compliant?

A: Yes, both CLA4611-085LF and SMP1304-079LF are ROHS3 compliant. The original HSMP-4810-TR2G RoHS status is not specified.

Q: What is the moisture sensitivity level for these parts?

A: All three parts, including the original and both substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions.

Q: Which substitute should be selected for RF switching applications?

A: Selection depends on circuit requirements. CLA4611-085LF provides higher current capability (1.5A) and voltage margin. SMP1304-079LF offers superior RF characteristics with the lowest capacitance and resistance values, suitable for high-frequency applications.
