CQ92N Equivalent & Substitute Parts

Part Overview

The CQ92N is an internally triggered TRIAC rated for 800 V off-state voltage and 1 A on-state current in a TO-92-3 through-hole package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The internally triggered configuration provides gate control with specified trigger voltage and current parameters suitable for AC switching applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CQ92N is determined by the following critical parameters:

• Voltage - Off State: 800 V minimum
• Current - On State (It (RMS)) (Max): 1 A minimum
• Mounting Type: Through Hole
• Package / Case: TO-92-3 compatible
• Operating Temperature Range: -40°C ~ 125°C minimum

The L0103NEAP from Littelfuse Inc. meets these core electrical and mechanical requirements. While the L0103NEAP features a logic-sensitive gate configuration (versus internally triggered), it maintains electrical compatibility across the specified voltage, current, and temperature parameters. The gate trigger specifications of the L0103NEAP (Vgt Max 1.3 V, Igt Max 3 mA) represent improved performance characteristics within the allowable substitution envelope.

Parameter Comparison

Engineering Selection Recommendations

The L0103NEAP is the qualified substitute for the CQ92N based on the following factors:

• Electrical compatibility: Both components share identical off-state voltage (800 V) and on-state current ratings (1 A maximum).
• Package compatibility: Both use TO-92-3 through-hole packaging with identical pinout and mechanical dimensions.
• Temperature range: Both operate across -40°C to 125°C, ensuring thermal compatibility in equivalent applications.
• Product status: The L0103NEAP is active and in production, providing supply continuity for the obsolete CQ92N.
• Compliance: The L0103NEAP is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements.

The L0103NEAP gate trigger specifications (Vgt Max 1.3 V, Igt Max 3 mA) are superior to the CQ92N specifications, indicating improved gate sensitivity and lower trigger current requirements.

Frequently Asked Questions (FAQ)

Q: Can the L0103NEAP directly replace the CQ92N in existing designs?

A: Yes. Both components share identical voltage and current ratings (800 V, 1 A), operate across the same temperature range (-40°C ~ 125°C), and use the same TO-92-3 package. Pinout compatibility is maintained.

Q: What is the difference between internally triggered and logic-sensitive gate configurations?

A: The CQ92N uses internal triggering, while the L0103NEAP uses a logic-sensitive gate. Both are TRIAC configurations suitable for AC switching. The L0103NEAP's logic-sensitive gate provides lower trigger voltage and current requirements, representing an enhancement over the CQ92N specification.

Q: Are there any compliance differences between these parts?

A: The CQ92N is RoHS non-compliant, while the L0103NEAP is ROHS3 compliant. Both are REACH unaffected and carry the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Q: What is the moisture sensitivity level for these components?

A: Both the CQ92N and L0103NEAP have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there other substitutes available for the CQ92N?

A: The L0103NEAP is the primary qualified substitute. The L0103NEAP itself lists Z0103NA 2AL2 and Z0107NA 5AL2 as further substitutes, which may also be evaluated for CQ92N replacement based on their electrical and package specifications.
