L2N3RP TRIAC Equivalent & Substitute Parts

Part Overview

The L2N3RP is a Logic - Sensitive Gate TRIAC rated for 200 V off-state voltage and 1 A on-state current in a Surface Mount DO-214 package. This component is classified as Obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and production continuity. The part maintains RoHS3 compliance and operates across the industrial temperature range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L2N3RP is determined by the following criteria:

Mandatory Compatibility Parameters:

• Triac Type: Logic - Sensitive Gate (must match)
• Current - On State (It (RMS)) (Max): 1 A (must match)
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V (must match)
• Current - Gate Trigger (Igt) (Max): 3 mA (must match)
• Current - Hold (Ih) (Max): 5 mA (must match)
• Operating Temperature: -40°C ~ 125°C (must match)
• Mounting Type: Surface Mount (must match)
• Package / Case: DO-214AA, SMB (3 Leads), Compak (must match)
• RoHS Status: RoHS3 Compliant (must match)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (must match)

Allowable Variation:

• Voltage - Off State: Higher voltage ratings are acceptable as they provide enhanced voltage margin while maintaining all other electrical characteristics

The substitute parts L4N3RP and L6N3RP meet all mandatory compatibility parameters. Both are Active status components with higher off-state voltage ratings (400 V and 600 V respectively), providing design flexibility for applications requiring additional voltage headroom.

Parameter Comparison

Engineering Selection Recommendations

Both L4N3RP and L6N3RP are qualified substitutes for the obsolete L2N3RP. Selection between these alternatives depends on application voltage requirements:

L4N3RP (400 V Rating): Suitable for applications requiring moderate voltage margin above the original 200 V specification. This part is in Active production status with 3200 units available in inventory.

L6N3RP (600 V Rating): Suitable for applications requiring maximum voltage margin. This part is in Active production status with 4080 units available in inventory.

Both substitute parts maintain identical gate trigger characteristics, on-state current ratings, hold current specifications, and thermal operating range as the original L2N3RP. All three parts share the same RoHS3 compliance status, MSL rating, and export classification codes.

Frequently Asked Questions (FAQ)

Q: Can L4N3RP or L6N3RP be used as direct replacements for L2N3RP?

A: Yes. Both parts are direct substitutes. They maintain identical gate trigger voltage (1.3 V maximum), gate trigger current (3 mA maximum), hold current (5 mA maximum), on-state current (1 A maximum), operating temperature range (-40°C to 125°C), and package configuration (DO-214AA, SMB 3-Lead, Compak). The higher voltage ratings provide additional design margin.

Q: What is the difference between L4N3RP and L6N3RP?

A: The primary difference is the off-state voltage rating. L4N3RP is rated for 400 V while L6N3RP is rated for 600 V. All other electrical and mechanical parameters are identical. Selection depends on the maximum voltage the application will encounter.

Q: Are there any package or mounting differences between these parts?

A: No. All three parts use identical Surface Mount packaging: DO-214AA, SMB (3 Leads), Compak configuration. They are mechanically and electrically interchangeable at the board level.

Q: Do all three parts meet the same compliance standards?

A: Yes. L2N3RP, L4N3RP, and L6N3RP are all RoHS3 compliant with MSL rating of 1 (Unlimited). They share the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Q: Why is L2N3RP marked as Obsolete?

A: The L2N3RP is classified as Obsolete, which is why substitute parts are necessary. L4N3RP and L6N3RP are both in Active production status and provide equivalent functionality with higher voltage ratings.
