Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMP-389B-TR2G is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Diode Type: PIN - Single (functional equivalence)
• Voltage Rating: Equal to or greater than 100V peak reverse voltage
• Current Rating: Equal to or greater than 1 A maximum current
• Capacitance and Resistance characteristics: Within acceptable operating ranges for RF applications
• Operating Temperature: Equal to or greater than 150°C (TJ)
• Moisture Sensitivity: MSL 1 or better
• Compliance: REACH Unaffected status maintained

The CLA4611-085LF from Skyworks Solutions Inc. meets these criteria with enhanced electrical performance (180V rating, 1.5 A current, 2 W power dissipation) and improved operating temperature (175°C). The substitute maintains PIN diode single-element topology and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

The CLA4611-085LF is suitable as a substitute for the HSMP-389B-TR2G based on the following factors:

• Product Status: The HSMP-389B-TR2G is Obsolete; the CLA4611-085LF is Active, ensuring long-term availability and supply chain continuity.
• Electrical Performance: The substitute exceeds the original part specifications in voltage rating (180V vs. 100V), current capacity (1.5 A vs. 1 A), and operating temperature (175°C vs. 150°C).
• Compliance: Both parts maintain REACH Unaffected status and EAR99 classification, preserving regulatory compliance.
• Functional Equivalence: Both are PIN - Single diode types, maintaining circuit topology compatibility.

Package differences (SC-70 SOT-323 vs. 3-QFN 2x2) require physical layout verification during implementation.

Frequently Asked Questions (FAQ)

Q: Can the CLA4611-085LF directly replace the HSMP-389B-TR2G in existing designs?

A: Electrical substitution is valid based on PIN diode topology and parameter compatibility. Physical package differences (SOT-323 vs. 3-QFN 2x2) require PCB layout modification and footprint verification.

Q: What are the key differences between these parts?

A: The CLA4611-085LF provides higher voltage rating (180V vs. 100V), higher current capacity (1.5 A vs. 1 A), lower resistance (1.2Ohm vs. 2.5Ohm), and higher operating temperature (175°C vs. 150°C). Both maintain identical MSL and REACH compliance.

Q: Why is the HSMP-389B-TR2G listed as Obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Broadcom Limited. The CLA4611-085LF from Skyworks Solutions Inc. is an Active product with ongoing availability.

Q: Are there any compliance concerns with substitution?

A: No. Both parts are REACH Unaffected and classified as EAR99, maintaining identical regulatory status.

Q: Does the lower resistance of the CLA4611-085LF affect circuit performance?

A: Lower resistance (1.2Ohm vs. 2.5Ohm) represents improved RF performance characteristics. Circuit validation is required to confirm compatibility with specific application requirements.
