ERO-S2PHF68R0 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF68R0 is a 68 Ohm ±1% 0.25W (1/4W) through-hole resistor with axial metal film construction manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications and compatible physical dimensions to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERO-S2PHF68R0 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 68 Ohms (exact match required)
• Tolerance: ±1% (maintains circuit accuracy specifications)
• Power Rating: 0.25W / 1/4W (thermal handling capability)
• Composition: Metal Film (ensures temperature coefficient and stability characteristics)
• Temperature Coefficient: ±50ppm/°C (frequency response and drift performance)
• Operating Temperature Range: Minimum -55°C ~ 150°C (environmental compatibility)
• Package Type: Axial (physical form factor for PCB mounting)
• Termination Count: 2 (circuit connectivity requirement)

The RNMF14FTC68R0 from Stackpole Electronics Inc meets all mandatory electrical parameters and maintains compatible physical dimensions within acceptable tolerances for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC68R0 is the qualified substitute for the obsolete ERO-S2PHF68R0 based on the following criteria:

Electrical Equivalence: Both components provide identical resistance (68 Ohms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±50ppm/°C). The RNMF14FTC68R0 extends the upper operating temperature limit to 155°C, providing enhanced thermal margin.

Physical Compatibility: Dimensional differences are minimal (0.003" diameter and 0.004" length variance). These tolerances fall within standard PCB pad and lead spacing specifications for axial through-hole components, ensuring mechanical fit without design modification.

Compliance Status: The RNMF14FTC68R0 is actively manufactured and carries ROHS3 and REACH compliance certifications, supporting current regulatory requirements. The ERO-S2PHF68R0 is obsolete and no longer in production.

Additional Features: The RNMF14FTC68R0 includes flame retardant coating and safety-rated construction, providing enhanced reliability characteristics beyond the original specification.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC68R0 be used as a direct replacement for the ERO-S2PHF68R0?

A: Yes. Both components share identical electrical specifications (68 Ohms ±1%, 0.25W, ±50ppm/°C) and compatible axial package geometry. Physical dimensions vary by less than 0.005 inches, which is within standard PCB tolerance for through-hole mounting.

Q: What is the significance of the dimensional difference between these parts?

A: The RNMF14FTC68R0 is 0.003 inches larger in diameter and 0.004 inches longer. These variations are within standard manufacturing tolerances for axial resistors and do not affect PCB pad spacing, lead hole sizing, or circuit performance.

Q: Why is the ERO-S2PHF68R0 listed as obsolete?

A: Panasonic has discontinued this product line. The RNMF14FTC68R0 from Stackpole Electronics Inc provides equivalent functionality with active manufacturing support and current compliance certifications.

Q: Are there compliance differences between these components?

A: The RNMF14FTC68R0 carries ROHS3 and REACH compliance certifications. The ERO-S2PHF68R0 compliance status is not specified in available documentation. For applications requiring regulatory compliance, the RNMF14FTC68R0 is the appropriate selection.

Q: Does the extended operating temperature range of the RNMF14FTC68R0 affect substitution suitability?

A: No. The extended upper temperature limit (155°C versus 150°C) provides additional thermal margin and does not create incompatibility. The component remains suitable for all applications within the original -55°C ~ 150°C specification.

Q: What is the significance of the flame retardant coating on the RNMF14FTC68R0?

A: The flame retardant coating and safety-rated construction are additional features that enhance component reliability. These features do not affect electrical performance or substitution compatibility; they represent an improvement over the original specification.
