TMOV14R150E Equivalent & Substitute Parts

Part Overview

The TMOV14R150E is a 240 V, 6 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc package (14mm). This component is designed for transient voltage protection in electronic circuits with a maximum DC voltage rating of 200 V and surge current capacity of 6 kA.

The TMOV14R150E is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TMOV14R150E is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (typical value 240 V, range 216 V – 264 V)
• Maximum DC voltage (200 V)
• Surge current capacity (6 kA)
• Energy absorption (60 J)
• Mounting type (through hole)
• Package form factor (disc 14mm)
• Single circuit configuration
• Operating temperature range (-55°C to 85°C)
• Thermal protection feature

The TMOV14RP150E meets all these criteria and is therefore a direct substitute. Additional cross-references (V14E150P, MOVTP14V150N) are identified as secondary equivalents within the Littelfuse varistor product family.

Parameter Comparison

Engineering Selection Recommendations

The TMOV14RP150E is the primary substitute for the obsolete TMOV14R150E. Both components are electrically and mechanically identical across all functional parameters. The key distinction is product status and regulatory compliance:

• TMOV14R150E: Obsolete product, RoHS non-compliant
• TMOV14RP150E: Active product, ROHS3 compliant, REACH unaffected

For new designs or ongoing production requiring transient voltage suppression at 240 V with 6 kA surge capacity, the TMOV14RP150E is the recommended selection. This part maintains full electrical and mechanical compatibility while providing current product support and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can TMOV14RP150E be used as a direct replacement for TMOV14R150E?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters, including varistor voltage (240 V typical), surge current (6 kA), energy absorption (60 J), and operating temperature range (-55°C to 85°C) are equivalent. Both use through-hole mounting in a 14mm disc package.

Q: What is the difference between TMOV14R150E and TMOV14RP150E?

A: The primary differences are product status and compliance. TMOV14R150E is obsolete and RoHS non-compliant. TMOV14RP150E is an active product that meets ROHS3 compliance standards. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use identical through-hole disc packaging (14mm). The TMOV14R150E is available in standard packaging, while TMOV14RP150E is supplied in bulk packaging. This does not affect electrical or mechanical compatibility.

Q: What parameters must match for a valid substitution?

A: Critical parameters for substitution include varistor voltage rating (240 V ±24 V), maximum DC voltage (200 V), surge current capacity (6 kA), energy absorption (60 J), mounting type (through hole), package form factor (disc 14mm), and operating temperature range (-55°C to 85°C).

Q: Is TMOV14RP150E suitable for RoHS-compliant applications?

A: Yes. TMOV14RP150E is ROHS3 compliant and REACH unaffected, making it suitable for applications requiring regulatory compliance. TMOV14R150E is not RoHS compliant.
