HSMS-286C-TR1G Equivalent & Substitute Parts

Part Overview

The HSMS-286C-TR1G is an RF Schottky diode manufactured by Broadcom Limited, configured as a 1-pair series connection with a 4V peak reverse voltage rating in SOT-323 packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part is suitable for RF applications requiring low-barrier Schottky diode performance in compact surface-mount packages.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMS-286C-TR1G is determined by the following critical parameters:

• Diode Type: Schottky - 1 Pair Series Connection (mandatory match)
• Package / Case: SOT-323 or compatible form factor
• Voltage - Peak Reverse (Max): 4V or higher
• Capacitance characteristics: Low-capacitance RF performance
• Operating Temperature: 150°C or higher
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Substitute parts are grouped based on voltage rating compatibility and active product status where available. Parts meeting or exceeding the electrical specifications of the main part are considered direct substitutes.

Engineering Selection Recommendations

Primary Substitute: BAT1504WH6327XTSA1

The BAT1504WH6327XTSA1 from Infineon Technologies is the preferred substitute. It matches the 4V peak reverse voltage specification of the main part, maintains SOT-323 packaging compatibility, supports the same 150°C operating temperature, and holds active product status. RoHS3 compliance and REACH unaffected status provide regulatory alignment for current manufacturing environments.

Secondary Substitute: MA4E2054B1-1146T

The MA4E2054B1-1146T from MACOM Technology Solutions is suitable for applications where the 3V peak reverse voltage rating is acceptable. This part is active and provides higher current capacity (20 mA) with lower power dissipation (75 mW). The operating temperature range (-65°C ~ 125°C) is narrower than the main part but covers standard industrial applications. SOT-323 packaging ensures mechanical compatibility.

Tertiary Substitute: SBX201C-TB-E

The SBX201C-TB-E from onsemi is applicable only for applications with 2V or lower voltage requirements. This part is obsolete and uses a different package form factor (TO-236-3, SC-59, SOT-23-3), requiring PCB layout modification. Selection of this part is limited to legacy designs or specific mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the MA4E2054B1-1146T replace the HSMS-286C-TR1G in all applications?

A: The MA4E2054B1-1146T has a 3V peak reverse voltage rating compared to the 4V rating of the main part. It is suitable only for circuits where the maximum reverse voltage does not exceed 3V. Operating temperature range is also narrower (-65°C ~ 125°C versus 150°C TJ).

Q: Is the BAT1504WH6327XTSA1 a direct pin-for-pin replacement?

A: Yes. The BAT1504WH6327XTSA1 uses SOT-323 packaging identical to the HSMS-286C-TR1G and maintains the same pinout for 1-pair series connection Schottky diodes. No PCB layout changes are required.

Q: Why is the SBX201C-TB-E listed as a substitute if it has a lower voltage rating?

A: The SBX201C-TB-E is included for reference in applications where voltage requirements are 2V or lower. However, its different package form factor (TO-236-3, SC-59, SOT-23-3) requires PCB modification and is not recommended for direct replacement.

Q: What is the impact of capacitance differences between substitute parts?

A: All substitute parts maintain capacitance values within 0.03pF of the main part (0.25pF to 0.35pF @ 0V, 1MHz). These variations are typical for RF Schottky diodes and do not significantly affect circuit performance in standard RF applications.

Q: Are all substitute parts RoHS and REACH compliant?

A: The BAT1504WH6327XTSA1 is explicitly RoHS3 compliant and REACH unaffected. The MA4E2054B1-1146T and SBX201C-TB-E do not list RoHS status in the provided specifications. Verify compliance requirements with your procurement or quality department before final selection.

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

A: All parts, including the main part and all substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
