V42MLA1206T Equivalent & Substitute Parts

Part Overview

The V42MLA1206T is a 53 V 180 A varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in surface mount applications. This component is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts must preserve the core functional parameters: 53 V nominal varistor voltage, 180 A surge current capability, 0.8 J energy rating, and 1206 (3216 Metric) package form factor.

Substitute Part Grouping Explanation

Substitute parts for the V42MLA1206T are identified based on strict parametric equivalence within the MLA series. The substitution criteria are:

• Varistor voltage range: 46 V (minimum) to 60 V (maximum), with 53 V typical value
• Surge current: 180 A
• Energy rating: 0.8 J
• Package: 1206 (3216 Metric) surface mount
• Mounting type: MLCV
• Operating temperature: -40°C to 125°C
• RoHS3 compliance
• Manufacturer: Littelfuse Inc.

The identified substitutes differ only in packaging configuration (Cut Tape & Digi-Reel versus Tape & Reel) and product status (Active versus Obsolete). All electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both V42MLA1206NH and V42MLA1206NT are parametric equivalents of the obsolete V42MLA1206T, with all electrical and mechanical specifications identical. Selection between these substitutes depends on procurement and assembly requirements:

V42MLA1206NH is supplied in Cut Tape (CT) and Digi-Reel® packaging, suitable for lower-volume applications and manual assembly processes.

V42MLA1206NT is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly operations.

Both substitutes maintain Active product status, ensuring long-term availability and supply chain continuity. Both comply with ROHS3 regulations and carry REACH Unaffected designation, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can V42MLA1206NH and V42MLA1206NT be used interchangeably with V42MLA1206T?

A: Yes. All three parts are parametrically identical in electrical performance and mechanical form factor. The differences are limited to packaging configuration and product lifecycle status.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging?

A: Cut Tape & Digi-Reel packaging is supplied in smaller quantities on cut tape spools, suitable for manual pick-and-place or lower-volume assembly. Tape & Reel packaging is supplied on continuous reels optimized for automated high-speed assembly equipment.

Q: Why is the original V42MLA1206T marked as obsolete?

A: Obsolete status indicates the part is no longer in active production. V42MLA1206NH and V42MLA1206NT are active alternatives that provide identical functionality with improved supply chain availability.

Q: Are there any compliance differences between the three parts?

A: No. All three parts are ROHS3 compliant and carry identical electrical certifications. V42MLA1206NH and V42MLA1206NT additionally carry REACH Unaffected designation.

Q: Will substituting these parts require PCB redesign?

A: No. All three parts use identical 1206 (3216 Metric) surface mount packages and MLCV mounting specifications, ensuring direct footprint compatibility without PCB modification.
