ERO-S2PHF2201 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF2201 is a 2.2 kOhms ±1% 0.25W through-hole resistor with axial metal film construction manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates across a temperature range of -55°C to 150°C and features a temperature coefficient of ±50ppm/°C, typical for metal film resistor applications requiring moderate precision and stability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERO-S2PHF2201 are qualified based on the following critical parameters:

• Resistance value: 2.2 kOhms (exact match required)
• Power rating: 0.25W minimum
• Package type: Axial configuration
• Composition: Metal film construction
• Operating temperature range: Must encompass or exceed -55°C to 150°C
• Tolerance: ±1% or better (tighter tolerance acceptable)
• Temperature coefficient: ±50ppm/°C or better

Two substitute parts meet these criteria with variations in secondary characteristics:

RNMF14FTC2K20 (Stackpole Electronics Inc) qualifies as a direct substitute with identical electrical specifications and active product status.

MFP-25BRD52-2K2 (YAGEO) qualifies as a substitute with enhanced tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C), though with larger physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

RNMF14FTC2K20 is the preferred direct substitute. This part maintains electrical equivalence with the ERO-S2PHF2201 while offering active product status, ensuring long-term availability. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Physical dimensions are nearly identical (0.070" Dia x 0.130" L versus 0.067" Dia x 0.126" L), minimizing PCB layout modifications. The operating temperature range extends to 155°C, providing additional thermal margin. Flame retardant coating and safety features provide enhanced reliability in demanding applications.

MFP-25BRD52-2K2 serves as an alternative when enhanced precision is required. The ±0.1% tolerance and ±25ppm/°C temperature coefficient represent significant improvements over the original specification. However, the larger physical dimensions (0.094" Dia x 0.248" L) may necessitate PCB layout adjustments. This part is suitable for applications where tighter tolerance and improved temperature stability justify the increased footprint.

Both substitute parts are ROHS3 compliant and REACH unaffected, supporting compliance with modern environmental and safety standards.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC2K20 be used as a direct replacement for ERO-S2PHF2201?

A: Yes. Both parts share identical resistance (2.2 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), and package type (axial). Physical dimensions are nearly equivalent, and the operating temperature range of RNMF14FTC2K20 (-55°C to 155°C) encompasses the original specification (-55°C to 150°C).

Q: What are the key differences between RNMF14FTC2K20 and MFP-25BRD52-2K2?

A: RNMF14FTC2K20 maintains specification parity with the original part (±1% tolerance, ±50ppm/°C). MFP-25BRD52-2K2 offers enhanced precision (±0.1% tolerance, ±25ppm/°C temperature coefficient) but has significantly larger physical dimensions (0.248" L versus 0.130" L). Selection depends on application requirements for tolerance and available PCB space.

Q: Will the slightly larger dimensions of RNMF14FTC2K20 affect PCB compatibility?

A: The dimensional difference is minimal (0.070" Dia x 0.130" L versus 0.067" Dia x 0.126" L). In most applications, this variation will not require PCB layout modifications. However, designs with tight component spacing should be verified.

Q: Are both substitute parts compliant with current environmental regulations?

A: Yes. Both RNMF14FTC2K20 and MFP-25BRD52-2K2 are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards.

Q: Why is the ERO-S2PHF2201 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Panasonic Electronic Components. Substitute parts from active manufacturers ensure continued availability and support for new designs and production runs.

Q: Can MFP-25BRD52-2K2 be used in applications requiring ±1% tolerance?

A: Yes. MFP-25BRD52-2K2 has ±0.1% tolerance, which is tighter than the ±1% requirement. The part exceeds the original specification and is suitable for applications requiring ±1% tolerance or better.
