ERA-S15J102V Equivalent & Substitute Parts

Part Overview

The ERA-S15J102V is a temperature-sensitive metal film resistor manufactured by Panasonic Electronic Components with a nominal resistance of 1 kOhms and a temperature coefficient of 1500ppm/°C. This component is designed for temperature correction circuits and operates across a range of -40°C to 125°C. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-S15J102V is based on the following critical parameters:

• Resistance value of 1 kOhms
• Surface mount package configuration
• Operating temperature range compatibility (-40°C to 125°C minimum)
• RoHS compliance status
• Temperature-sensitive application suitability

The substitute part 32207615 (Yageo Nexensos) meets these core requirements as an active product with equivalent resistance, surface mount configuration, and extended operating temperature range. Both components are RoHS compliant and suitable for temperature sensing applications.

Parameter Comparison

Engineering Selection Recommendations

The 32207615 is an active substitute for the obsolete ERA-S15J102V. Both components maintain RoHS compliance and MSL Level 1 ratings, ensuring compatibility with modern manufacturing and environmental standards. The substitute offers improved tolerance (±0.12% versus ±5%) and an extended operating temperature range (-50°C to 130°C versus -40°C to 125°C), providing additional design margin. The higher temperature coefficient of the substitute (3850ppm/°C versus 1500ppm/°C) represents a functional difference that must be evaluated against specific circuit requirements for temperature correction applications.

Frequently Asked Questions (FAQ)

Q: Can the 32207615 directly replace the ERA-S15J102V in existing designs?

A: Both components share the same 1 kOhms resistance value and surface mount configuration. However, the temperature coefficient differs significantly (3850ppm/°C versus 1500ppm/°C). Direct substitution is possible only if the circuit design tolerates this difference in temperature sensitivity.

Q: What is the package size difference between these parts?

A: The 32207615 is specified as 0805 (2012 Metric) package. The ERA-S15J102V package dimensions are not provided in the available data.

Q: Are both parts RoHS compliant?

A: Yes. The ERA-S15J102V is ROHS3 compliant, and the 32207615 is RoHS compliant. Both meet current environmental regulations.

Q: What is the significance of the tolerance difference?

A: The 32207615 offers ±0.12% tolerance compared to ±5% for the ERA-S15J102V. This tighter tolerance may improve circuit accuracy in temperature correction applications but does not prevent substitution in designs that accept the original ±5% specification.

Q: Does the extended temperature range of the substitute provide an advantage?

A: The 32207615 operates from -50°C to 130°C versus -40°C to 125°C for the ERA-S15J102V. This extended range provides additional design margin for applications requiring operation at temperature extremes.
