2N5064RP Equivalent & Substitute Parts

Part Overview

The 2N5064RP is a sensitive gate SCR (silicon controlled rectifier) rated for 200 V off-state voltage and 800 mA RMS current in a TO-92 through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The 2N5064RP remains available in inventory but replacement with active-status alternatives ensures long-term supply chain reliability and access to current manufacturing processes.

Substitute Part Grouping Explanation

Substitution of the 2N5064RP is determined by the following critical parameters:

SCR Type: Must be Sensitive Gate
Mounting Type: Must be Through Hole
Package / Case: Must be TO-92-3 (TO-226AA)
Gate Trigger Voltage (Vgt): Maximum 800 mV
Gate Trigger Current (Igt): Maximum 200 µA
Current - Hold (Ih): Maximum 5 mA
RoHS Compliance: ROHS3 Compliant

The substitute parts listed below meet these core requirements. The 2N6565RP provides a direct upgrade path with increased off-state voltage (400 V) while maintaining identical gate trigger characteristics and current ratings. The STMicroelectronics P0102DA series (1AA3, 2AL3, 5AL3) offers equivalent performance with active product status and extended operating temperature range.

Engineering Selection Recommendations

2N6565RP is the direct Littelfuse equivalent with active product status. It maintains identical gate trigger specifications and current ratings while providing doubled off-state voltage capability (400 V vs. 200 V). This part is suitable for applications requiring the same gate sensitivity and current handling as the original 2N5064RP but with enhanced voltage margin.

P0102DA 1AA3, P0102DA 2AL3, and P0102DA 5AL3 are STMicroelectronics alternatives with active product status and extended operating temperature range (-40°C to 125°C vs. -110°C). These parts maintain gate trigger compatibility and RMS current ratings. The on-state voltage specification is slightly higher (1.95 V vs. 1.7 V), and off-state leakage current is higher (10 µA vs. 1 µA). These differences are within acceptable tolerances for most sensitive gate SCR applications. Selection among the three P0102DA variants depends on packaging and inventory requirements: P0102DA 1AA3 is supplied in bulk, while P0102DA 2AL3 and P0102DA 5AL3 are supplied in cut tape.

All substitute parts maintain ROHS3 compliance and moisture sensitivity level 1 (unlimited).

Frequently Asked Questions (FAQ)

Q: Can the 2N6565RP directly replace the 2N5064RP in existing designs?

A: Yes. The 2N6565RP maintains identical gate trigger voltage (800 mV max), gate trigger current (200 µA max), and RMS current rating (800 mA). The increased off-state voltage (400 V vs. 200 V) provides additional voltage margin without affecting gate sensitivity or current handling characteristics. No circuit modifications are required.

Q: What are the differences between the STMicroelectronics P0102DA variants?

A: The P0102DA 1AA3, P0102DA 2AL3, and P0102DA 5AL3 are electrically identical. They differ only in packaging: P0102DA 1AA3 is supplied in bulk, while P0102DA 2AL3 and P0102DA 5AL3 are supplied in cut tape. Selection depends on assembly process requirements and inventory management.

Q: Are there differences in on-state voltage between the 2N5064RP and STMicroelectronics alternatives?

A: Yes. The 2N5064RP specifies a maximum on-state voltage (Vtm) of 1.7 V, while the P0102DA series specifies 1.95 V maximum. This 0.25 V difference is within typical application tolerances for sensitive gate SCR circuits and does not affect functional compatibility.

Q: Do the substitute parts have the same package dimensions?

A: Yes. All substitute parts use the TO-92-3 (TO-226AA) package with formed leads, maintaining identical PCB footprint and through-hole mounting compatibility with the 2N5064RP.

Q: Why is the 2N5064RP classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The substitute parts listed—particularly the 2N6565RP and P0102DA series—are actively manufactured and provide equivalent or superior performance for new designs and production continuity.
