ERA-S15J471V Equivalent & Substitute Parts

Part Overview

The ERA-S15J471V is a 470 Ohm temperature-sensitive metal film resistor manufactured by Panasonic Electronic Components, rated at 0.1W (1/10W) with ±5% tolerance. Designed for temperature correction circuits, this component features a temperature coefficient of 1500ppm/°C and operates across -40°C to 125°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute components must maintain the same resistance value, tolerance, and core electrical characteristics while accommodating modern packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-S15J471V is determined by the following critical parameters:

• Resistance Value: 470 Ohms (exact match required)
• Tolerance: ±5% (maintains specification accuracy)
• Power Rating: Minimum 0.1W (substitute may exceed this rating)
• Mounting Type: Surface Mount (SMD compatibility)
• Compliance: ROHS3 and REACH compliance maintained

The CRCW0805470RJNEA from Vishay Dale meets these core substitution criteria. While the substitute exhibits a lower temperature coefficient (±200ppm/°C versus 1500ppm/°C) and higher power rating (0.125W versus 0.1W), it maintains identical resistance, tolerance, and surface mount configuration. The expanded operating temperature range (-55°C to 155°C) and automotive AEC-Q200 qualification provide enhanced reliability margins for most applications.

Parameter Comparison

Engineering Selection Recommendations

The CRCW0805470RJNEA qualifies as a direct functional substitute based on matching resistance, tolerance, and compliance certifications. The component's active product status ensures long-term availability and supply chain continuity, addressing the obsolescence of the ERA-S15J471V. The AEC-Q200 automotive qualification and expanded operating temperature range provide additional reliability assurance for demanding applications. Both components maintain ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the CRCW0805470RJNEA directly replace the ERA-S15J471V in existing designs?

A: Yes, for applications where the 470 Ohm resistance and ±5% tolerance are the primary functional requirements. The substitute maintains identical electrical specifications for resistance and tolerance while offering improved availability and active product status.

Q: What is the significance of the different temperature coefficients?

A: The ERA-S15J471V exhibits 1500ppm/°C, characteristic of temperature-sensitive applications. The CRCW0805470RJNEA shows ±200ppm/°C, typical of standard thick film resistors. Applications requiring precise temperature compensation should evaluate whether the substitute's lower temperature coefficient affects circuit performance.

Q: Are there package compatibility considerations?

A: Both components are surface mount devices. The CRCW0805470RJNEA uses the 0805 (2012 Metric) package format. PCB layout and footprint compatibility must be confirmed before implementation.

Q: Does the higher power rating of the substitute create any concerns?

A: No. The CRCW0805470RJNEA's 0.125W rating exceeds the ERA-S15J471V's 0.1W requirement, providing additional thermal margin without adverse effects on circuit operation.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the ERA-S15J471V and CRCW0805470RJNEA maintain ROHS3 compliance and are REACH unaffected, meeting current environmental and regulatory requirements.
