Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V42MLA1206NT are identified based on the following critical parameters that determine functional equivalence:

• Varistor Voltage Range: 46 V (Min) to 60 V (Typ/Max at 53 V)
• Current - Surge Rating: 180 A
• Maximum DC Volts: 42 V
• Maximum AC Volts: 30 V
• Energy Absorption: 0.8 J
• Package / Case: 1206 (3216 Metric) Surface Mount
• Number of Circuits: 1
• Operating Temperature: -40°C ~ 125°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The V42MLA1206NH qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, thermal performance, and mechanical compatibility. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) & Digi-Reel® format. This distinction affects procurement and assembly processes but does not impact electrical or thermal performance.

Parameter Comparison

Engineering Selection Recommendations

Both the V42MLA1206NT and V42MLA1206NH are Active products from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

The V42MLA1206NT in Tape & Reel format is suitable for high-volume automated assembly operations requiring continuous reel feeding. The V42MLA1206NH in Cut Tape & Digi-Reel® format provides flexibility for lower-volume production runs or mixed-component assembly scenarios. Both parts deliver identical electrical performance, thermal characteristics, and reliability in transient voltage suppression applications rated for 53 V typical operation and 180 A surge current handling.

Frequently Asked Questions (FAQ)

Q: Can V42MLA1206NH be used as a direct replacement for V42MLA1206NT?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, thermal performance, and mechanical compatibility. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), which does not affect circuit performance.

Q: What determines if a varistor can substitute for the V42MLA1206NT?

A: Substitute parts must match the following critical parameters: Varistor Voltage range (46-60 V with 53 V typical), Current - Surge rating (180 A), Maximum DC Volts (42 V), Maximum AC Volts (30 V), Energy absorption (0.8 J), 1206 (3216 Metric) package, and operating temperature range (-40°C ~ 125°C).

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape & Digi-Reel® formats contain identical components. Packaging format only impacts procurement logistics and assembly line compatibility.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both V42MLA1206NT and V42MLA1206NH are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for industrial and commercial applications.

Q: What is the Moisture Sensitivity Level for these parts?

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