HSMP-3892-TR1 Equivalent & Substitute Parts

Part Overview

The HSMP-3892-TR1 is an RF Diode PIN in a 1 Pair Series Connection configuration, rated for 100V peak reverse voltage and 1A maximum current. Manufactured by Broadcom Limited, this component is packaged in SOT-23-3 (TO-236-3, SC-59) and is currently classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying functionally compatible substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF PIN diodes is determined by the following criteria:

• Diode Configuration: Must be PIN - 1 Pair Series Connection
• Package Compatibility: Must use SOT-23-3 (TO-236-3, SC-59) form factor for direct PCB replacement
• Voltage Rating: Substitute must meet or exceed the 100V peak reverse voltage requirement
• Current Handling: Substitute must support the application's current demands
• Electrical Characteristics: Capacitance and resistance parameters must be compatible with RF circuit performance requirements
• Moisture Sensitivity: MSL rating must be acceptable for storage and assembly conditions

The BAR66E6327HTSA1 meets these substitution criteria through identical package geometry, compatible electrical performance envelope, and active product status with established supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The BAR66E6327HTSA1 is the manufacturer-recommended substitute for the obsolete HSMP-3892-TR1. Selection should be based on the following factors:

Product Status: The HSMP-3892-TR1 is obsolete with no active manufacturing. The BAR66E6327HTSA1 is an active product with 143,839 units in stock, ensuring supply continuity.

Compliance: The BAR66E6327HTSA1 is ROHS3 compliant, meeting current regulatory requirements. The original part is RoHS non-compliant, which may present procurement or end-market restrictions.

Package Compatibility: Both parts use identical SOT-23-3 packaging, enabling direct PCB replacement without layout modifications.

Electrical Performance: The substitute meets or exceeds the original part's voltage rating (150V vs. 100V). Current rating is lower (200 mA vs. 1 A); verify that application current requirements do not exceed 200 mA. Capacitance and resistance characteristics differ; circuit simulation or bench testing is appropriate to confirm RF performance in the specific application context.

Certifications: Both parts carry identical MSL ratings and ECCN classifications, with no REACH restrictions.

Frequently Asked Questions (FAQ)

Q: Can the BAR66E6327HTSA1 directly replace the HSMP-3892-TR1 on the PCB?

A: Yes. Both parts use the SOT-23-3 package with identical pinout and footprint, enabling direct PCB replacement without layout changes.

Q: What is the key difference in current rating between these parts?

A: The HSMP-3892-TR1 is rated for 1 A maximum current, while the BAR66E6327HTSA1 is rated for 200 mA. Verify that your application current does not exceed 200 mA. If higher current is required, alternative parts must be evaluated.

Q: How do the capacitance values differ, and does this matter?

A: The HSMP-3892-TR1 has 0.3pF capacitance at 5V, while the BAR66E6327HTSA1 has 0.6pF at 35V. In RF applications, capacitance affects circuit tuning and frequency response. Evaluate the impact on your specific RF circuit through simulation or testing.

Q: Is the BAR66E6327HTSA1 RoHS compliant?

A: Yes. The BAR66E6327HTSA1 is ROHS3 compliant. The original HSMP-3892-TR1 is RoHS non-compliant. If your end market or procurement policy requires RoHS compliance, the substitute meets this requirement.

Q: Why is the original part obsolete?

A: The HSMP-3892-TR1 is classified as obsolete by Broadcom Limited. Obsolescence typically results from product line consolidation, technology advancement, or market transition. The BAR66E6327HTSA1 represents the active alternative in Infineon's RF PIN diode portfolio.

Q: Are there any REACH or export restrictions on the substitute?

A: No. The BAR66E6327HTSA1 carries REACH Unaffected status and EAR99 ECCN classification, identical to the original part. No additional export or regulatory restrictions apply.

Q: What is the operating temperature range for the substitute?

A: The BAR66E6327HTSA1 datasheet does not specify an operating temperature range in the provided parameters. Consult the manufacturer's datasheet for thermal specifications if operating temperature is a critical design parameter.
