Substitute Part Grouping Explanation

Substitution of the QJ6006DH2RP is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Off State: 600 V
• Current - On State (It (RMS)) (Max): 6 A
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V
• Current - Gate Trigger (Igt) (Max): 10 mA
• Current - Hold (Ih) (Max): 25 mA
• Current - Non Rep. Surge 50, 60Hz (Itsm): 60A, 72A
• Operating Temperature Range: -40°C to 150°C (TJ)

Mechanical & Packaging Equivalence Criteria:

• Triac Type: Alternistor - Snubberless
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Configuration: Single

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all electrical parameters, operate within the specified temperature range, maintain identical package footprint and pinout, and satisfy all regulatory compliance requirements. Parts within the QJxx06xHx series sharing these specifications are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both QJ6006DH2RP and QJ6006DH3RP are active-status components manufactured by Littelfuse Inc. and maintain full compliance with ROHS3 and REACH regulatory requirements. All electrical parameters, thermal operating ranges, and mechanical package specifications are identical between the two parts. Selection between these substitutes is based on availability and supply chain considerations, as both components satisfy identical functional and compliance requirements for AC switching applications requiring 600 V, 6 A snubberless TRIAC Alternistor functionality in TO-252 surface mount packages.
