Substitute Part Grouping Explanation

Substitute parts for the V5.5MLA1206WH are determined by strict equivalence across the following critical parameters:

• Maximum DC Volts: 5.5 V
• Varistor Voltage (Typical): 8.2 V
• Current - Surge: 150 A
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCV
• Operating Temperature Range: -40°C ~ 125°C (TA)
• Series: MLA
• RoHS Status: ROHS3 Compliant

The identified substitute parts maintain identical electrical and mechanical specifications. The primary distinction between the main part and substitutes is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Both V5.5MLA1206NH and V5.5MLA1206NT are direct parametric equivalents to the obsolete V5.5MLA1206WH. Selection between these active alternatives should be based on packaging and procurement requirements:

V5.5MLA1206NH and V5.5MLA1206NT are both supplied in Tape & Reel (TR) packaging and maintain active product status with Littelfuse Inc. Both parts carry ROHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment for current manufacturing environments. The electrical and mechanical specifications are identical across all three part numbers, confirming direct substitutability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can V5.5MLA1206NH or V5.5MLA1206NT be used as direct replacements for V5.5MLA1206WH?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (5.5 V maximum DC, 8.2 V typical varistor voltage, 150 A surge current), mechanical package (1206 / 3216 Metric), and operating temperature range (-40°C to 125°C). The primary difference is product status; V5.5MLA1206WH is obsolete while the alternatives are active.

Q: What is the difference between V5.5MLA1206NH and V5.5MLA1206NT?

A: Both parts are electrically and mechanically identical. The difference lies in packaging configuration and inventory availability. Both are supplied in Tape & Reel (TR) format and carry active product status.

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

A: No. All three parts maintain ROHS3 compliance, identical ECCN (EAR99) classification, and the same HTSUS code (8533.40.4000). Moisture sensitivity level is 1 (Unlimited) for all variants.

Q: Can these varistors be used in both AC and DC applications?

A: These components are rated for both AC and DC operation. Maximum AC voltage is 4 V and maximum DC voltage is 5.5 V. Application design must respect these voltage limits.

Q: What is the package footprint compatibility?

A: All three parts use the 1206 (3216 Metric) surface mount package with MLCV mounting type. PCB footprints and reflow profiles are identical across all variants.
