HSMS-286C-TR2G Equivalent & Substitute Parts

Part Overview

The HSMS-286C-TR2G 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-capacitance Schottky diode performance in compact surface-mount packages.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMS-286C-TR2G is determined by the following critical parameters:

• Diode Type: Schottky - 1 Pair Series Connection (mandatory match)
• Package / Case: SOT-323 or compatible footprint (SC-70)
• Voltage - Peak Reverse (Max): 4V or higher
• Capacitance @ Vr, F: 0.25pF or lower preferred for RF performance
• Operating Temperature: 150°C (TJ) or higher
• Moisture Sensitivity Level: MSL 1 or equivalent

The substitute parts listed below meet these core electrical and mechanical requirements, enabling direct or near-direct replacement in RF circuit applications.

Parameter Comparison

Engineering Selection Recommendations

BAT1504WH6327XTSA1 (Infineon Technologies) is the primary substitute for HSMS-286C-TR2G. This part maintains identical voltage and temperature ratings, shares the same SOT-323 package footprint, and is currently in active production status. The BAT1504WH6327XTSA1 provides higher current capacity (110 mA vs. unspecified for the main part) and greater power dissipation capability (100 mW), making it suitable for applications requiring enhanced performance margins. ROHS3 compliance and unlimited MSL rating ensure compatibility with modern manufacturing and storage requirements.

SBX201C-TB-E (onsemi) is a secondary substitute option with the same diode configuration and operating temperature. However, this part has a reduced peak reverse voltage rating of 2V compared to the 4V requirement of the main part, limiting its applicability to lower-voltage RF circuits. The package footprint differs (SOT-23-3 vs. SOT-323), requiring PCB layout modifications. Additionally, SBX201C-TB-E is classified as obsolete, offering no long-term procurement advantage.

For new designs or long-term production continuity, BAT1504WH6327XTSA1 is the recommended choice due to active product status and full parameter compatibility.

Frequently Asked Questions (FAQ)

Q: Can BAT1504WH6327XTSA1 be used as a direct replacement for HSMS-286C-TR2G?

A: Yes. Both parts share identical peak reverse voltage (4V), operating temperature (150°C), and SOT-323 package specifications. The BAT1504WH6327XTSA1 has slightly higher capacitance (0.35pF vs. 0.25pF), which may affect high-frequency performance in sensitive RF circuits. Verification through circuit simulation or prototype testing is recommended for applications operating near the upper frequency limits.

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

A: SBX201C-TB-E meets the core substitution criteria of diode type, configuration, and package family compatibility. However, its 2V peak reverse voltage rating is insufficient for applications requiring the full 4V specification of the main part. This part is suitable only for circuits designed for 2V operation or lower.

Q: What are the package compatibility considerations?

A: BAT1504WH6327XTSA1 uses PG-SOT323 packaging, which is footprint-compatible with the SC-70/SOT-323 of the main part. SBX201C-TB-E uses 3-CP packaging (SOT-23-3 family), which requires PCB layout changes and is not a direct footprint replacement.

Q: Are there compliance or certification differences between these parts?

A: BAT1504WH6327XTSA1 carries ROHS3 compliance certification, while the main part and SBX201C-TB-E do not specify RoHS status. All three parts are REACH Unaffected and carry EAR99 ECCN classification. MSL ratings are identical across all parts (MSL 1, Unlimited).

Q: What is the procurement status impact?

A: HSMS-286C-TR2G is obsolete, making future availability uncertain. BAT1504WH6327XTSA1 is in active production with substantial inventory (20,483 pcs), ensuring long-term availability. SBX201C-TB-E is also obsolete, offering no procurement advantage over the main part.
