• Current - Surge: 40 kA
• Maximum AC Volts: 200 V
• Maximum DC Volts: 265 V
• Energy: 430 J
• Capacitance @ 1 MHz: 6500 pF
• Operating Temperature Range: -55°C to 85°C

Mechanical Parameters (Must Match):

• Package / Case: Square 34mm, Formed Tabs, 3-Lead
• Mounting Type: Through Hole
• Number of Circuits: 1
• Features: Thermally Protected

All identified substitutes maintain identical electrical and mechanical specifications, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

TMOV34S201MP is the primary direct substitute for the obsolete TMOV34S201M. This part maintains identical electrical and mechanical specifications while offering the advantage of active product status. TMOV34S201MP is ROHS3 compliant and REACH unaffected, providing improved regulatory compliance compared to the original part.

TMOV34S201MPX2696 is a parametric equivalent offering identical electrical and mechanical performance. This variant is also active, ROHS3 compliant, and REACH unaffected. Selection between TMOV34S201MP and TMOV34S201MPX2696 may be determined by packaging availability, inventory levels, or specific procurement requirements.

Both substitute parts are suitable for direct replacement in applications currently using TMOV34S201M, with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can TMOV34S201MP be used as a direct replacement for TMOV34S201M?

A: Yes. TMOV34S201MP is electrically and mechanically identical to TMOV34S201M. All electrical parameters, including varistor voltage, surge current rating, and energy dissipation, are equivalent. The through-hole mounting configuration and square 34mm package dimensions are identical, enabling direct board-level substitution.

Q: What is the difference between TMOV34S201MP and TMOV34S201MPX2696?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The designation suffix "X2696" indicates a specific manufacturing or packaging variant. Both are active products with ROHS3 compliance and REACH unaffected status. Selection between these variants should be based on availability and procurement requirements.

Q: Why is the original TMOV34S201M listed as obsolete?

A: The TMOV34S201M is obsolete due to product lifecycle management by Littelfuse Inc. Active substitutes TMOV34S201MP and TMOV34S201MPX2696 provide equivalent functionality with improved regulatory compliance, including ROHS3 certification.

Q: Are there any compliance differences between the original part and substitutes?

A: Yes. The original TMOV34S201M is RoHS non-compliant. Both substitute parts (TMOV34S201MP and TMOV34S201MPX2696) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Will substituting these parts require PCB modifications?

A: No. The substitute parts maintain identical package dimensions (square 34mm), lead configuration (3-lead formed tabs), and through-hole mounting type. No PCB layout changes are required.

Q: What inventory status should be considered when selecting a substitute?

A: TMOV34S201MP has 1088 pieces in stock, while TMOV34S201MPX2696 has 1044 pieces in stock. Both substitutes offer adequate inventory availability for procurement planning.
