2N692 Equivalent & Substitute Parts

Part Overview

The 2N692 is an SCR (Silicon Controlled Rectifier) rated for 800V off-state voltage with 25A RMS on-state current, designed for standard recovery applications in chassis and stud mount configurations. Manufactured by Central Semiconductor Corp, this component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part operates across a temperature range of -65°C to 125°C and is packaged in TO-48 format.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N692 is determined by electrical and mechanical parameter compatibility within the thyristor category. The primary substitution criteria are:

Electrical Parameters (Critical):

• Off-state voltage rating: 800V minimum
• Gate trigger voltage (Vgt): 2V maximum
• Gate trigger current (Igt): 40mA maximum
• On-state voltage (Vtm): 2V maximum
• On-state current (RMS): 25A minimum
• Hold current (Ih): must not exceed application requirements
• SCR type: Standard Recovery

Mechanical Parameters (Critical):

• Mounting type: Chassis, Stud Mount
• Package compatibility: TO-208AA or TO-48 equivalent
• Operating temperature range: -65°C to 125°C minimum

The VS-2N692 manufactured by Vishay General Semiconductor meets all specified electrical and mechanical parameters, with identical voltage ratings, gate trigger specifications, and thermal operating range. Package compatibility is maintained through TO-208AA (TO-48) equivalence.

Parameter Comparison

*Compatible indicates the substitute parameter is equal to or more stringent than the original specification.

Engineering Selection Recommendations

The VS-2N692 is the direct manufacturer-recommended substitute for the obsolete 2N692. Selection is based on the following factors:

Product Status: The 2N692 is obsolete and no longer manufactured by Central Semiconductor Corp. The VS-2N692 is an active product with current manufacturing and supply availability.

Electrical Compatibility: All critical electrical parameters match or exceed the original specification. The VS-2N692 demonstrates lower hold current (20mA vs. 100mA) and off-state leakage current (2mA vs. 4mA), representing improved performance characteristics. Non-repetitive surge current is slightly lower (145-150A vs. 200A) but remains within acceptable margins for standard recovery SCR applications.

Regulatory Compliance: The VS-2N692 is ROHS3 compliant and carries EAR99 ECCN classification, whereas the 2N692 is RoHS non-compliant with obsolete ECCN status. For applications requiring regulatory compliance, the VS-2N692 is the appropriate selection.

Package Compatibility: Both parts utilize equivalent stud mount configurations with TO-48 form factor compatibility (TO-208AA designation for the VS-2N692 represents the same physical package).

Frequently Asked Questions (FAQ)

Q: Can the VS-2N692 be used as a direct replacement for the 2N692 in existing designs?

A: Yes. The VS-2N692 meets all electrical and mechanical specifications of the 2N692. The identical voltage ratings, gate trigger parameters, on-state current rating, and operating temperature range ensure functional equivalence. Package compatibility is maintained through TO-48 form factor equivalence.

Q: What are the differences in electrical performance between the 2N692 and VS-2N692?

A: The VS-2N692 exhibits lower hold current (20mA vs. 100mA) and reduced off-state leakage current (2mA vs. 4mA), both representing improved performance. Non-repetitive surge current is specified at 145-150A compared to 200A for the original part. These differences do not affect substitution suitability for standard recovery SCR applications.

Q: Are there packaging considerations when substituting the VS-2N692 for the 2N692?

A: Both parts use identical stud mount configurations and TO-48 form factor packaging. No mechanical modifications or board layout changes are required for substitution.

Q: Does the VS-2N692 meet current regulatory requirements?

A: Yes. The VS-2N692 is ROHS3 compliant and carries EAR99 ECCN classification, meeting current regulatory standards. The original 2N692 is RoHS non-compliant and carries obsolete ECCN status.

Q: What is the basis for the VS-2N692 substitution recommendation?

A: The VS-2N692 is the manufacturer-recommended substitute specified in the 2N692 product documentation. Substitution is based on matching electrical parameters (800V off-state voltage, 2V gate trigger voltage, 40mA gate trigger current, 2V on-state voltage, 25A RMS on-state current), identical SCR type (Standard Recovery), matching operating temperature range (-65°C to 125°C), and compatible stud mount packaging.
