Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S02F1R00X is based on strict equivalence of the following critical parameters:

• Resistance Value: 1 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: -100 / +600 ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Automotive Qualification: AEC-Q200 (exact match required)
• Anti-Sulfur Feature: Present (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part ERJ-U02F1R00X meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02F1R00X and ERJ-U02F1R00X are active production parts from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Compliance and Certifications: Both parts maintain ROHS3 compliance, REACH unaffected status, and automotive AEC-Q200 qualification. Both are suitable for applications requiring automotive-grade reliability and environmental compliance.

Packaging Format: Both parts are supplied in Tape & Reel (TR) format, ensuring compatibility with automated assembly equipment.

Electrical Performance: Identical resistance value, tolerance, power rating, temperature coefficient, and operating temperature range ensure direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F1R00X be used as a direct replacement for ERJ-S02F1R00X?

A: Yes. The ERJ-U02F1R00X is electrically and mechanically equivalent to the ERJ-S02F1R00X. All critical parameters including resistance, tolerance, power rating, package dimensions, temperature characteristics, and automotive qualifications are identical.

Q: Are there any differences in the physical package between these two parts?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). They are mechanically interchangeable on PCBs designed for either part number.

Q: Do both parts meet automotive standards?

A: Yes. Both the ERJ-S02F1R00X and ERJ-U02F1R00X carry AEC-Q200 automotive qualification and feature anti-sulfur coating, making them suitable for automotive applications requiring high reliability.

Q: What is the difference between the ERJ-S02 and ERJ-U02 series designations?

A: The series designation difference (S02 versus U02) reflects different product lines within Panasonic's resistor portfolio. However, for the specified 1 Ohm ±1% 0.1W 0402 configuration, both series provide identical electrical and mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERJ-S02F1R00X and ERJ-U02F1R00X are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts have an operating temperature range of -55°C ~ 155°C and identical temperature coefficients of -100 / +600 ppm/°C, ensuring consistent performance across the full temperature range.
