Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMP-3864-TR2G is determined by the following critical parameters:

• Diode Type: PIN - 1 Pair Common Cathode configuration (functional equivalence)
• Package / Case: SOT-23-3 form factor (mechanical and thermal compatibility)
• Voltage - Peak Reverse (Max): Must equal or exceed 50V (electrical safety margin)
• Current - Max: Must support application requirements
• Capacitance and Resistance characteristics: Must be compatible with RF circuit performance
• Moisture Sensitivity Level: MSL 1 (Unlimited) preferred for supply chain consistency

The identified substitute parts meet these criteria while maintaining functional compatibility within RF diode applications.

Parameter Comparison

Engineering Selection Recommendations

BAP70-05,215 (NXP USA Inc.) is the primary substitute recommendation. This part maintains electrical equivalence at the 50V peak reverse voltage specification, shares identical SOT-23-3 packaging, and carries Active product status with ROHS3 compliance. The extended operating temperature range (-65°C to 150°C) provides additional thermal margin compared to the original part.

BAP64-05-TP (Micro Commercial Co) serves as an alternative substitute with elevated voltage rating (175V), providing additional design margin for applications requiring higher reverse voltage tolerance. However, this part is classified as Obsolete, which may present long-term supply constraints. The reduced maximum current (100 mA versus 1 A) requires verification against application requirements.

Both substitute parts maintain the PIN - 1 Pair Common Cathode diode type and SOT-23-3 package compatibility. Selection between BAP70-05,215 and BAP64-05-TP depends on specific application voltage and current requirements, with BAP70-05,215 preferred for new designs due to Active status and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can BAP70-05,215 directly replace HSMP-3864-TR2G in existing designs?

A: Yes. Both parts share identical peak reverse voltage (50V), SOT-23-3 packaging, and PIN - 1 Pair Common Cathode configuration. The primary design consideration is the reduced maximum current rating (100 mA for BAP70-05,215 versus 1 A for HSMP-3864-TR2G). Verify that application current requirements do not exceed 100 mA.

Q: What is the difference between BAP64-05-TP and BAP70-05,215?

A: BAP64-05-TP operates at 175V peak reverse voltage, providing higher voltage margin. BAP70-05,215 matches the original 50V specification. BAP70-05,215 is preferred for direct substitution due to Active product status. BAP64-05-TP is suitable only when elevated voltage tolerance is required.

Q: Are there thermal or operating temperature differences?

A: Both substitute parts support the full -65°C to 150°C operating range, which exceeds the original part's 150°C maximum. This provides additional thermal design margin.

Q: Do the substitute parts meet compliance requirements?

A: Both BAP64-05-TP and BAP70-05,215 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original part's compliance profile.

Q: What are the capacitance and resistance differences?

A: Capacitance values are comparable (0.2pF to 0.35pF range), with minimal impact on RF circuit performance. Resistance at 100mA, 100MHz ranges from 1.35Ohm to 1.9Ohm. Verify RF performance characteristics for specific circuit applications.
