QJ6016NH2RP Equivalent & Substitute Parts

Part Overview

The QJ6016NH2RP is an Alternistor-type TRIAC manufactured by Littelfuse Inc., rated for 600V off-state voltage and 16A on-state current in a surface mount TO-263 (D2PAK) package. This snubberless design is actively produced and widely stocked. Substitute parts are identified based on matching electrical ratings, package compatibility, and compliance certifications to support procurement flexibility and supply chain continuity.

RoHS Status	ROHS3 Compliant
Moisture Sensitivity Level (MSL)	1 (Unlimited)

Substitute Part Grouping Explanation

Substitution eligibility for the QJ6016NH2RP is determined by the following criteria:

Off-state voltage rating of 600V or higher
On-state current rating of 16A or higher
Gate trigger voltage (Vgt) of 1.3V or lower
Gate trigger current (Igt) of 10mA or lower
Hold current (Ih) of 15mA or lower
Surface mount D2PAK package compatibility
Single configuration
Active product status
ROHS3 compliance

The T1610-600G-TR from STMicroelectronics meets all substitution criteria. While classified as a Logic-type TRIAC with sensitive gate characteristics rather than Alternistor-type, it maintains electrical parameter compatibility within the specified tolerances and package footprint.

Engineering Selection Recommendations

Both the QJ6016NH2RP and T1610-600G-TR are active products with ROHS3 compliance and unlimited moisture sensitivity ratings. The primary distinction is the operating temperature range: the QJ6016NH2RP supports -40°C to 150°C, while the T1610-600G-TR is rated to -40°C to 125°C. Applications requiring operation above 125°C junction temperature must use the QJ6016NH2RP. For applications within the 125°C limit, both parts are electrically equivalent and package-compatible. Non-repetitive surge current ratings differ slightly (QJ6016NH2RP: 167A/200A vs. T1610-600G-TR: 160A/168A at 50/60Hz), which may be relevant for transient protection requirements.

Frequently Asked Questions (FAQ)

Q: Can the T1610-600G-TR directly replace the QJ6016NH2RP on a PCB?

A: Yes, both parts use the TO-263-3 D2PAK package with identical pinout and footprint. No PCB layout modifications are required.

Q: What is the difference between Alternistor and Logic TRIAC types?

A: Both are TRIAC variants with different internal gate structures. The Alternistor type (QJ6016NH2RP) is optimized for snubberless operation, while the Logic type (T1610-600G-TR) features sensitive gate characteristics. Both meet the specified electrical parameters for this application.

Q: Are there temperature limitations when substituting?

A: The T1610-600G-TR has a maximum junction temperature of 125°C, compared to 150°C for the QJ6016NH2RP. Applications requiring sustained operation above 125°C must use the QJ6016NH2RP.

Q: Do both parts meet regulatory compliance requirements?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Both have MSL rating of 1 (unlimited moisture sensitivity).

Q: What are the surge current differences?

A: The QJ6016NH2RP is rated for 167A (50Hz) and 200A (60Hz) non-repetitive surge current. The T1610-600G-TR is rated for 160A (50Hz) and 168A (60Hz). Applications with high transient current requirements should verify compatibility with the lower T1610-600G-TR ratings.
