HVR250P180CF Equivalent & Substitute Parts

Part Overview

The HVR250P180CF is a polymeric PTC resettable fuse manufactured by Littelfuse Inc., rated for 60V maximum voltage with 180 mA hold current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The part operates across a temperature range of -40°C to 85°C and is housed in a through-hole radial disc package. Substitute parts must maintain electrical compatibility while meeting current application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HVR250P180CF is determined by the following critical electrical parameters:

• Voltage rating (60V maximum)
• Hold current (180 mA)
• Trip current (650 mA nominal)
• Initial resistance (800 mOhms minimum)
• Post-trip resistance (4 Ohms maximum)
• Operating temperature range (-40°C to 85°C)
• Through-hole radial disc package configuration

Substitute parts are grouped into two categories:

Direct Electrical Equivalents (180 mA Hold Current): Parts maintaining the exact 180 mA hold current specification with 60V voltage rating and compatible resistance characteristics.

Functional Alternatives (Lower Hold Current): Parts with reduced hold current (120 mA or 150 mA) that operate at the same voltage and temperature range but with different trip characteristics. These are suitable only where the lower hold current threshold is acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Equivalent): The 250R180F from Littelfuse Inc. is the direct electrical equivalent to the HVR250P180CF. Both parts maintain identical voltage, hold current, trip current, and resistance specifications. The 250R180F is currently in active production status with higher inventory availability (1394 pcs) compared to the obsolete HVR250P180CF. This part is ROHS3 compliant and carries cURus and TUV approvals.

Alternative with Higher Voltage Rating: The TRF250-180 from Littelfuse Inc. provides the same 180 mA hold current and 650 mA trip current but with a 100V maximum voltage rating. This part is suitable for applications where higher voltage headroom is beneficial. It carries expanded certifications (CSA, TUV, UL) and is actively produced.

Lower Current Alternatives: The 0ZRF0015FF1E and 0ZRF0015FF2B from Bel Fuse Inc. operate at 150 mA hold current with 60V voltage rating. These parts are suitable only where the reduced hold current threshold is compatible with circuit requirements. The 0ZRF0012FF1E and 0ZRF0012FF2B provide 120 mA hold current and are applicable only to designs tolerating this lower threshold.

All substitute options maintain the -40°C to 85°C operating temperature range and through-hole radial disc package configuration. Selection should be based on specific voltage requirements, hold current tolerance, and packaging format (bulk, box, or tape & reel).

Frequently Asked Questions (FAQ)

Q: Can the 250R180F directly replace the HVR250P180CF?

A: Yes. The 250R180F is electrically identical to the HVR250P180CF, maintaining the same 60V voltage rating, 180 mA hold current, 650 mA trip current, and resistance specifications. Both are through-hole radial disc packages. The primary difference is product status: HVR250P180CF is obsolete while 250R180F is in active production.

Q: What is the difference between the TRF250-180 and the 250R180F?

A: Both parts maintain 180 mA hold current and 650 mA trip current. The TRF250-180 has a 100V maximum voltage rating compared to the 250R180F's 60V rating. The TRF250-180 carries additional certifications (CSA, UL) and has a faster trip time (2 seconds versus 20 seconds). Select TRF250-180 for applications requiring higher voltage tolerance.

Q: Can I use the 0ZRF0015FF1E as a substitute?

A: The 0ZRF0015FF1E operates at 150 mA hold current instead of 180 mA. This part is suitable only if your circuit design can tolerate a lower hold current threshold. The voltage rating (60V) and operating temperature range match the original part. Verify that the reduced hold current does not compromise circuit protection requirements.

Q: What is the difference between packaging options (Box, Bulk, Tape & Reel)?

A: Packaging format affects order quantity and handling. Box packaging typically contains smaller quantities suitable for prototyping or low-volume assembly. Bulk packaging is for larger quantities without tape or reel. Tape & Reel (TR) packaging is standard for automated pick-and-place assembly equipment. Electrical specifications remain identical across all packaging formats for the same part number.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the environmental compliance of the original HVR250P180CF.

Q: What certifications should I verify for my application?

A: The 250R180F carries cURus and TUV approvals. The TRF250-180 carries CSA, TUV, and UL approvals. The Bel Fuse 0ZRF series parts carry cURus and TUV approvals. Verify that the certifications of your selected substitute meet your application's regulatory requirements.
