ERO-S2PHF2700 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF2700 is a 270 Ohm ±1% 1/4W axial metal film through-hole resistor manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production, maintenance, and repair applications. The ERO series represents a legacy product line, and active alternatives with identical electrical specifications are available from current manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF2700 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 270 Ohms (exact match required)
• Tolerance: ±1% (no deviation permitted)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (required for performance equivalence)
• Temperature coefficient: ±50ppm/°C (required for stability equivalence)
• Operating temperature range: minimum -55°C to 150°C (substitute must meet or exceed this range)
• Package type: Axial (mechanical compatibility requirement)
• Number of terminations: 2 (pin count equivalence)

The RNMF14FTC270R from Stackpole Electronics Inc meets all substitution criteria and is classified as an active product with current manufacturing status.

Engineering Selection Recommendations

The RNMF14FTC270R is a direct functional equivalent to the ERO-S2PHF2700 for applications requiring a 270 Ohm ±1% 1/4W axial metal film resistor. Selection of this substitute is supported by:

• Identical electrical specifications across resistance, tolerance, power rating, and temperature coefficient
• Operating temperature range that exceeds the original specification (-55°C to 155°C versus -55°C to 150°C)
• Active product status with current manufacturing availability
• ROHS3 compliance certification
• Axial package compatibility with existing PCB layouts and through-hole assembly processes
• Minor dimensional variation (0.070" diameter and 0.130" length versus 0.067" diameter and 0.126" length) remains within standard axial resistor tolerance ranges and does not affect mechanical fit in standard component spacing

The RNMF14FTC270R is suitable for direct substitution in new designs, production runs, and field replacements where the ERO-S2PHF2700 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC270R be used as a direct replacement for the ERO-S2PHF2700?

A: Yes. Both components share identical electrical specifications: 270 Ohms, ±1% tolerance, 0.25W power rating, metal film composition, and ±50ppm/°C temperature coefficient. Both are packaged in axial configuration with two terminations. The substitute meets or exceeds all critical parameters.

Q: What is the difference in physical dimensions between these parts?

A: The RNMF14FTC270R has a slightly larger diameter (0.070" versus 0.067") and length (0.130" versus 0.126"). These minor variations are within standard axial resistor tolerances and do not affect compatibility with standard PCB layouts or component spacing.

Q: Why is the ERO-S2PHF2700 listed as obsolete?

A: The ERO series represents a legacy product line from Panasonic Electronic Components. Obsolete status indicates that the manufacturer has discontinued production. The RNMF14FTC270R from Stackpole Electronics Inc provides an active alternative with equivalent specifications.

Q: Does the RNMF14FTC270R have better compliance certifications?

A: The RNMF14FTC270R carries ROHS3 compliance certification. Both components share the same ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Q: What is the operating temperature advantage of the substitute?

A: The RNMF14FTC270R operates across -55°C to 155°C, providing a 5°C upper temperature margin compared to the ERO-S2PHF2700 (-55°C to 150°C). This extended range offers additional thermal headroom in high-temperature applications.

Q: Are there any packaging differences?

A: The RNMF14FTC270R is supplied in Cut Tape (CT) packaging. Both components are axial through-hole resistors suitable for manual and automated assembly processes.
