ERO-S2PHF2R15 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF2R15 is a 2.15 Ohm ±1% metal film axial resistor rated at 0.25W (1/4W) for through-hole applications. Manufactured by Panasonic Electronic Components, this part operates across -55°C to 150°C with a temperature coefficient of ±50ppm/°C. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERO-S2PHF2R15 is determined by matching the following critical parameters:

• Resistance value: 2.15 Ohms (exact match required)
• Tolerance: ±1% (equivalent precision)
• Composition: Metal film (maintains electrical characteristics)
• Package: Axial through-hole configuration
• Temperature coefficient: ±50ppm/°C (stability requirement)
• Operating temperature range: minimum -55°C to 150°C coverage

The MBB02070C2158FRP00 qualifies as a direct substitute based on these parameters. While it features a higher power rating (0.6W versus 0.25W), this represents an upgrade that maintains backward compatibility in circuit applications. The substitute meets or exceeds all critical electrical and environmental specifications.

Engineering Selection Recommendations

The MBB02070C2158FRP00 is the qualified substitute for the obsolete ERO-S2PHF2R15. Selection is based on:

• Electrical equivalence: Identical resistance, tolerance, and temperature coefficient
• Environmental compliance: ROHS3 compliance of the substitute supports modern manufacturing standards
• Product availability: Active status ensures continued supply and procurement reliability
• Thermal performance: Extended operating range (-55°C to 155°C) provides additional margin
• Power rating upgrade: The 0.6W rating of the substitute exceeds the original 0.25W specification, eliminating thermal stress in equivalent applications

Frequently Asked Questions (FAQ)

Q: Can the MBB02070C2158FRP00 replace the ERO-S2PHF2R15 in existing designs?

A: Yes. Both parts share identical resistance (2.15 Ohms), tolerance (±1%), composition (metal film), and temperature coefficient (±50ppm/°C). The substitute's higher power rating (0.6W) is compatible with circuits designed for 0.25W operation.

Q: What is the physical difference between these parts?

A: The MBB02070C2158FRP00 has larger dimensions (0.098" Dia x 0.256" L) compared to the ERO-S2PHF2R15 (0.067" Dia x 0.126" L) due to its higher power rating. PCB layout verification is required before substitution.

Q: Are there packaging differences?

A: The ERO-S2PHF2R15 uses standard axial packaging. The MBB02070C2158FRP00 is supplied in Tape & Reel (TR) format, which is standard for production environments.

Q: Does the substitute meet current compliance requirements?

A: Yes. The MBB02070C2158FRP00 is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: Why is the ERO-S2PHF2R15 obsolete?

A: Panasonic has discontinued this part number. The MBB02070C2158FRP00 provides functional equivalence with active manufacturer support and modern compliance certifications.
