HVF1206T2004FE Equivalent & Substitute Parts

Part Overview

The HVF1206T2004FE is a 2 MOhms ±1% 0.3W chip resistor in 1206 (3216 Metric) package manufactured by Ohmite. This high voltage, moisture-resistant thick film resistor is designed for applications requiring non-magnetic components with extended temperature range operation from -55°C to 200°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HVF1206T2004FE is based on the following critical parameters:

• Resistance Value: 2 MOhms exact match required
• Tolerance: ±1% maintained
• Package: 1206 (3216 Metric) form factor for PCB compatibility
• Composition: Thick film technology
• Temperature Coefficient: ±100ppm/°C stability
• Moisture Sensitivity: MSL 1 classification

The ESR18EZPF2004 from Rohm Semiconductor meets these core substitution criteria. While the power rating differs (0.5W versus 0.3W), the higher rating provides design margin. The operating temperature range of the substitute (-55°C ~ 155°C) covers the primary operational window, though the upper limit is reduced compared to the original part.

Engineering Selection Recommendations

The ESR18EZPF2004 is the primary substitute for the obsolete HVF1206T2004FE. Selection of this substitute is supported by:

• Active Product Status: The ESR18EZPF2004 is currently in active production, ensuring long-term availability and supply chain stability.
• Compliance Certifications: ROHS3 compliance and AEC-Q200 automotive qualification provide regulatory alignment and quality assurance.
• Electrical Equivalence: Matching resistance, tolerance, and temperature coefficient values ensure functional compatibility in circuit applications.
• Package Compatibility: Identical 1206 (3216 Metric) package enables direct PCB layout substitution without redesign.
• Power Margin: The 0.5W rating exceeds the original 0.3W specification, providing additional thermal headroom in power dissipation scenarios.

Design applications operating above 155°C require evaluation of the reduced upper temperature limit relative to the original 200°C specification.

Frequently Asked Questions (FAQ)

Q: Can the ESR18EZPF2004 be used as a direct replacement on existing PCBs designed for the HVF1206T2004FE?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical footprint dimensions (0.126" L x 0.063" W). Direct PCB substitution is possible without layout modification.

Q: What is the significance of the power rating difference between 0.3W and 0.5W?

A: The higher power rating of the ESR18EZPF2004 indicates greater thermal dissipation capability. This provides design margin and does not create compatibility issues in applications designed for 0.3W operation.

Q: Are there temperature range limitations when substituting the ESR18EZPF2004?

A: The substitute operates from -55°C to 155°C, compared to the original -55°C to 200°C range. Applications requiring sustained operation above 155°C must evaluate thermal performance or consider alternative solutions.

Q: What compliance advantages does the ESR18EZPF2004 offer?

A: The substitute provides ROHS3 compliance and AEC-Q200 automotive qualification, supporting regulatory requirements and quality standards applicable to automotive and industrial applications.

Q: Are the electrical characteristics identical between the two parts?

A: Yes. Both parts maintain 2 MOhms resistance, ±1% tolerance, and ±100ppm/°C temperature coefficient. Electrical performance in circuit applications is equivalent.

Q: What is the MSL (Moisture Sensitivity Level) classification for both parts?

A: Both the HVF1206T2004FE and ESR18EZPF2004 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
