Key Parameters

Substitute Part Grouping Explanation

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

• Diode Configuration: PIN - 1 Pair Common Cathode (must match)
• Package Type: SOT-23-3 (TO-236-3, SC-59) (must match for PCB compatibility)
• Voltage Rating: Peak reverse voltage must be equal to or greater than 50V
• Current Capability: Maximum current must be equal to or greater than 1 A
• Electrical Characteristics: Capacitance and resistance values must be compatible with circuit design requirements

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

BAP70-05,215 (NXP USA Inc.) is the primary substitute option. This part maintains the 50V peak reverse voltage rating of the original HSMP-3864-TR1, ensuring direct electrical compatibility. The BAP70-05,215 carries Active product status and is ROHS3 compliant, providing long-term supply availability and regulatory compliance for new designs.

BAP64-05-TP (Micro Commercial Co) is an alternative substitute with elevated voltage rating (175V) and ROHS3 compliance. This part is suitable for applications where higher voltage margin is required. However, the reduced maximum current rating (100 mA versus 1 A) must be evaluated against circuit requirements. This part carries Obsolete status.

Both substitute parts are packaged in SOT-23-3 format and maintain the PIN - 1 Pair Common Cathode configuration, ensuring mechanical and functional compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can BAP64-05-TP be used as a direct replacement for HSMP-3864-TR1?

A: BAP64-05-TP is mechanically compatible (SOT-23-3 package) and functionally equivalent (PIN - 1 Pair Common Cathode configuration). However, the maximum current rating is reduced from 1 A to 100 mA. Substitution is valid only if circuit current requirements do not exceed 100 mA. The elevated voltage rating (175V) provides additional design margin.

Q: Why is BAP70-05,215 recommended over BAP64-05-TP?

A: BAP70-05,215 maintains the 50V voltage rating of the original part and carries Active product status, ensuring continued availability. Both parts are ROHS3 compliant. BAP70-05,215 is the preferred choice for new designs requiring long-term supply security.

Q: Are all substitute parts in the same package?

A: Yes. HSMP-3864-TR1, BAP64-05-TP, and BAP70-05,215 are all packaged in SOT-23-3 (TO-236-3, SC-59) format. No PCB layout modifications are required for substitution.

Q: What is the impact of different capacitance values on circuit performance?

A: Capacitance values are provided at different measurement conditions. HSMP-3864-TR1 is specified at 0.2pF @ 50V, 1MHz. BAP64-05-TP and BAP70-05,215 are specified at 0.35pF and 0.3pF respectively @ 20V, 1MHz. Circuit designers must verify that these capacitance variations are acceptable for the intended RF application.

Q: What compliance considerations apply to these parts?

A: HSMP-3864-TR1 is RoHS non-compliant. Both substitute parts (BAP64-05-TP and BAP70-05,215) are ROHS3 compliant. For new production requiring RoHS compliance, either substitute part is acceptable. All three parts are REACH Unaffected and classified as EAR99.
