Substitute Part Grouping Explanation

Substitution eligibility for the V9MLN41206WT is determined by strict equivalence across the following critical parameters:

• Varistor Voltage range: 11 V (Min) to 16 V (Max), with 14.6 V typical
• Current - Surge rating: 30 A
• Number of Circuits: 4
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCV
• Operating Temperature Range: -55°C ~ 125°C (TA)
• Maximum AC Volts: 6.5 V
• Maximum DC Volts: 9 V
• Energy: 0.1 J
• Capacitance @ Frequency: 300 pF @ 1 MHz

The substitute part V9MLN41206WH meets all electrical and mechanical parameters identically to the main part. The primary distinction is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The V9MLN41206WH is the direct equivalent substitute for the obsolete V9MLN41206WT. Both parts are manufactured by Littelfuse and share identical electrical specifications, mechanical dimensions, and environmental ratings. The V9MLN41206WH maintains active product status, ensuring ongoing availability and supply chain support.

Both parts comply with ROHS3 requirements and carry identical export classification (EAR99) and tariff codes (HTSUS 8533.40.4000). The moisture sensitivity level of 1 (Unlimited) applies to both variants, indicating no special moisture handling requirements during storage or assembly.

The primary operational difference is packaging format: V9MLN41206WH is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. This packaging format does not affect electrical or mechanical performance and is compatible with automated pick-and-place equipment.

Frequently Asked Questions (FAQ)

Q: Can V9MLN41206WH be used as a direct replacement for V9MLN41206WT in existing designs?

A: Yes. The V9MLN41206WH is electrically and mechanically identical to the V9MLN41206WT across all specified parameters. No design modifications are required for substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The V9MLN41206WT is obsolete and no longer manufactured. The V9MLN41206WH is actively produced by Littelfuse, ensuring reliable supply availability for new production runs and field replacements.

Q: Does the Tape & Reel packaging of V9MLN41206WH affect compatibility?

A: No. Tape & Reel packaging is a standard delivery format for surface mount components and is fully compatible with automated assembly processes. The component itself is identical regardless of packaging format.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status, EAR99 export classification, and HTSUS tariff codes. Both have MSL rating of 1 (Unlimited), requiring no special moisture handling.

Q: What are the critical parameters that define substitution eligibility for this varistor?

A: Substitution is based on matching varistor voltage range (11-16 V typical 14.6 V), surge current rating (30 A), circuit count (4), package format (1206 / 3216 Metric), mounting type (Surface Mount MLCV), and operating temperature range (-55°C to 125°C).
