ERO-S2PHF1500 Equivalent & Substitute Parts

Part Overview

The ERO-S2PHF1500 is a 150 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 ERO-S2PHF1500 is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications requiring this resistance value and tolerance specification.

Substitute Part Grouping Explanation

Substitution for the ERO-S2PHF1500 is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Package configuration: Axial through-hole
• Operating temperature range: Minimum -55°C to 150°C or higher
• Termination count: 2

The RNMF14FTC150R from Stackpole Electronics Inc meets all substitution criteria. This part is currently in active production status with high inventory availability, making it a direct functional equivalent for the obsolete ERO-S2PHF1500.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC150R is the direct substitute for the obsolete ERO-S2PHF1500. Both parts share identical electrical specifications: 150 Ohm resistance, ±1% tolerance, 0.25W power rating, metal film composition, and ±50ppm/°C temperature coefficient. The operating temperature range of the RNMF14FTC150R extends to 155°C, exceeding the original part's 150°C maximum.

Physical dimensions differ slightly: the RNMF14FTC150R measures 0.070" diameter by 0.130" length compared to the original 0.067" by 0.126". These dimensional variations remain within typical axial resistor tolerances and do not affect electrical performance or standard PCB footprint compatibility.

The RNMF14FTC150R carries active product status with ROHS3 compliance and REACH unaffected certification, providing regulatory compliance advantages over the obsolete original part. Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Frequently Asked Questions (FAQ)

Q: Can the RNMF14FTC150R replace the ERO-S2PHF1500 in existing designs?

A: Yes. The RNMF14FTC150R meets all electrical and mechanical substitution criteria. Resistance, tolerance, power rating, temperature coefficient, and operating temperature range are equivalent or superior. Axial package configuration and two-termination design ensure direct compatibility with existing through-hole PCB layouts.

Q: What are the physical dimension differences between these parts?

A: The RNMF14FTC150R is slightly larger: 0.070" diameter by 0.130" length versus the original 0.067" by 0.126". These differences fall within standard axial resistor manufacturing tolerances and do not impact PCB footprint compatibility or circuit performance.

Q: Does the RNMF14FTC150R have better temperature performance?

A: The RNMF14FTC150R operates to 155°C maximum, compared to the ERO-S2PHF1500 at 150°C. Both maintain identical ±50ppm/°C temperature coefficient. The extended upper temperature limit of the substitute provides additional thermal margin in high-temperature applications.

Q: What regulatory certifications does the RNMF14FTC150R carry?

A: The RNMF14FTC150R is ROHS3 compliant and REACH unaffected. Both parts share EAR99 export classification and 8533.21.0090 HTSUS code.

Q: Is the RNMF14FTC150R currently available?

A: Yes. The RNMF14FTC150R is in active production status with 41,238 pieces in stock, providing reliable supply for production and maintenance requirements.
