Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMP-3860-TR2G is determined by the following criteria:

Electrical Compatibility Requirements:

• Diode Type: PIN - Single (functional category match)
• Voltage - Peak Reverse (Max): Must equal or exceed 50V
• Current - Max: Must equal or exceed 1A
• Resistance @ If, F: Must be within acceptable operating range (1.5Ohm @ 100mA, 100MHz reference)
• Capacitance @ Vr, F: Must support RF switching performance at specified frequency

Thermal & Environmental Requirements:

• Operating Temperature: Must support minimum 150°C (TJ)
• Moisture Sensitivity Level: MSL 1 or equivalent

Physical Requirements:

• Package compatibility: SOT-23-3 or equivalent footprint

The identified substitute parts meet these criteria with the following considerations:

CLA4606-085LF exceeds voltage and current ratings (75V, 1.5A) with improved thermal performance (175°C) and higher power dissipation capability (3W), suitable for applications requiring enhanced margin.

SMP1302-001LF provides significantly higher voltage rating (200V) with reduced power dissipation (250mW) in identical SOT-23-3 packaging, applicable where voltage headroom is prioritized.

Parameter Comparison

Engineering Selection Recommendations

CLA4606-085LF is the primary recommended substitute for new designs and procurement. This part is Active status with ROHS3 compliance, providing superior electrical performance margins (75V/1.5A versus 50V/1A) and enhanced thermal capability (175°C junction temperature). The 3-QFN package requires PCB layout modification from the original SOT-23-3 footprint. This substitute is suitable for applications where component longevity and regulatory compliance are prioritized.

SMP1302-001LF provides an alternative for applications requiring higher voltage rating (200V) while maintaining SOT-23-3 package compatibility. However, this part is also Obsolete status, limiting its utility for long-term supply chain stability. ROHS3 compliance is confirmed. This option is applicable only where existing SOT-23-3 layouts must be preserved and voltage headroom is a critical design parameter.

For applications requiring immediate substitution with minimal redesign, CLA4606-085LF is the preferred choice despite package differences, as it offers Active product status and superior performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can CLA4606-085LF be used as a direct pin-for-pin replacement for HSMP-3860-TR2G?

A: No. CLA4606-085LF uses a 3-QFN (2x2) package versus the SOT-23-3 package of the original part. PCB layout and footprint redesign is required. However, electrical performance is fully compatible and exceeds original specifications.

Q: What are the key electrical differences between the substitute parts?

A: CLA4606-085LF provides higher voltage (75V) and current (1.5A) ratings with 3W power dissipation capability. SMP1302-001LF provides the highest voltage rating (200V) but with lower power dissipation (250mW). Both maintain the 1.5Ohm resistance characteristic at 100MHz.

Q: Why is CLA4606-085LF recommended over SMP1302-001LF?

A: CLA4606-085LF has Active product status, ensuring long-term availability and supply chain support. SMP1302-001LF is Obsolete, presenting the same procurement challenges as the original HSMP-3860-TR2G. Both are ROHS3 compliant.

Q: Are there thermal performance differences between these parts?

A: Yes. CLA4606-085LF operates to 175°C junction temperature with 3W power dissipation capability. SMP1302-001LF operates to 150°C ambient temperature with 250mW power dissipation. CLA4606-085LF provides superior thermal margin for high-power RF applications.

Q: What is the capacitance impact of substitution?

A: CLA4606-085LF exhibits 0.38pF @ 6V versus the original 0.2pF @ 50V. SMP1302-001LF exhibits 0.3pF @ 30V. Capacitance variation affects RF switching speed and frequency response. Circuit simulation is required to confirm performance in specific RF applications.

Q: Are all substitute parts MSL 1 rated?

A: Yes. All parts listed, including the original HSMP-3860-TR2G, carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.
