2N2324A Equivalent & Substitute Parts

Part Overview

The 2N2324A is a sensitive gate SCR (Silicon Controlled Rectifier) rated for 100 V off-state operation with a maximum gate trigger current of 20 µA. Manufactured by Microchip Technology, this component is housed in a TO-5 metal can package and is qualified to MIL-PRF-19500/276 military standards. The 2N2324A is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations where military-grade sensitive gate SCRs are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N2324A is determined by equivalence in the following critical parameters:

• Voltage Rating (Off State): Both the main part and substitute must support 100 V off-state operation
• SCR Type: Both must be classified as sensitive gate SCRs
• Gate Trigger Characteristics: Gate trigger voltage and current specifications must be compatible with circuit design requirements
• On-State Current Capability: The substitute must support the required average on-state current
• Hold Current: The substitute must meet or exceed the hold current specification
• Operating Temperature Range: The substitute must cover the required temperature envelope
• Mounting Type: Through-hole mounting is required for direct board-level compatibility

The P0130AA 1EA3 manufactured by STMicroelectronics meets these substitution criteria. Both devices are sensitive gate SCRs with 100 V off-state ratings, through-hole mounting configurations, and compatible gate trigger characteristics. The P0130AA 1EA3 provides enhanced on-state current capability (500 mA average, 800 mA RMS) compared to the 2N2324A (220 mA average), making it suitable for applications requiring higher current handling. The substitute operates across a -40°C to 125°C temperature range, which overlaps the 2N2324A operating window.

Parameter Comparison

Engineering Selection Recommendations

The P0130AA 1EA3 is an active production substitute for the obsolete 2N2324A. Both devices share the same off-state voltage rating (100 V) and sensitive gate SCR classification, establishing functional equivalence for circuit-level operation.

Product Status Consideration: The 2N2324A is obsolete, while the P0130AA 1EA3 is in active production. Selection of the P0130AA 1EA3 ensures long-term component availability and supply chain continuity.

Compliance Difference: The 2N2324A carries military qualification (MIL-PRF-19500/276) and is RoHS non-compliant. The P0130AA 1EA3 is ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements. Applications requiring military-grade qualification must evaluate whether the P0130AA 1EA3 meets specific procurement standards.

Temperature Range: The 2N2324A operates from -65°C to 125°C, while the P0130AA 1EA3 operates from -40°C to 125°C. Applications requiring operation below -40°C must retain the 2N2324A or identify alternative solutions.

Package Consideration: The 2N2324A uses TO-5 metal can packaging, while the P0130AA 1EA3 uses TO-92-3 plastic packaging. PCB layout modifications are required for physical substitution.

Frequently Asked Questions (FAQ)

Q: Can the P0130AA 1EA3 directly replace the 2N2324A in existing designs?

A: Electrical substitution is valid based on matching off-state voltage (100 V), sensitive gate SCR type, and compatible gate trigger characteristics. Physical substitution requires PCB layout modification due to different package types (TO-5 versus TO-92-3). Gate trigger voltage tolerance increases from 600 mV to 800 mV maximum, which must be evaluated against circuit design margins.

Q: What are the key differences in gate trigger characteristics?

A: The 2N2324A specifies a maximum gate trigger current of 20 µA, while the P0130AA 1EA3 specifies 1 µA. The P0130AA 1EA3 requires significantly less gate current for triggering. Gate trigger voltage increases from 600 mV to 800 mV maximum. Circuits designed for the 2N2324A gate characteristics must be re-evaluated for the P0130AA 1EA3.

Q: Is the P0130AA 1EA3 suitable for applications requiring military qualification?

A: The 2N2324A carries MIL-PRF-19500/276 military qualification. The P0130AA 1EA3 does not carry this qualification. Applications with military procurement requirements must verify whether the P0130AA 1EA3 meets specific qualification standards or whether the 2N2324A must be retained.

Q: What is the impact of the lower operating temperature limit on the P0130AA 1EA3?

A: The 2N2324A operates from -65°C to 125°C, while the P0130AA 1EA3 operates from -40°C to 125°C. Applications requiring operation below -40°C cannot use the P0130AA 1EA3 as a substitute.

Q: How do the on-state current ratings compare?

A: The 2N2324A supports 220 mA average on-state current. The P0130AA 1EA3 supports 500 mA average on-state current and 800 mA RMS on-state current. The P0130AA 1EA3 provides higher current handling capability, making it suitable for applications requiring increased current capacity.

Q: What packaging considerations apply to substitution?

A: The 2N2324A uses TO-5 metal can (3-pin) packaging. The P0130AA 1EA3 uses TO-92-3 plastic (3-pin) packaging. Pin configurations are compatible, but physical dimensions and PCB footprints differ. PCB layout and mechanical mounting modifications are required for physical substitution.

Q: Does the P0130AA 1EA3 meet current environmental compliance standards?

A: Yes. The P0130AA 1EA3 is ROHS3 compliant and REACH unaffected. The 2N2324A is RoHS non-compliant. Applications subject to environmental regulations benefit from P0130AA 1EA3 selection.
