Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02J9R1X is determined by strict equivalence across the following parameters:

• Electrical Specifications: Resistance value (9.1 Ohms), tolerance (±5%), and power rating (0.1W) must be identical
• Package Dimensions: 0402 (1005 Metric) form factor with matching physical dimensions (0.039" L x 0.020" W, 0.016" max height)
• Material Composition: Thick film construction with anti-sulfur coating
• Automotive Compliance: AEC-Q200 qualification required
• Environmental Specifications: Operating temperature range (-55°C ~ 155°C) and temperature coefficient (-100 / +600 ppm/°C) must be maintained
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating required

The ERJ-U02J9R1X meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02J9R1X and ERJ-U02J9R1X are active production components manufactured by Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is based on packaging and inventory requirements:

ERJ-S02J9R1X is supplied in standard packaging configuration with 980 pieces currently in stock.

ERJ-U02J9R1X is supplied in Tape & Reel (TR) packaging configuration with 10,614 pieces currently in stock, providing higher availability for high-volume production requirements.

Both parts maintain full compliance with ROHS3 regulations, AEC-Q200 automotive qualification, and MSL 1 moisture sensitivity rating. The selection between these equivalent parts does not impact circuit performance, thermal characteristics, or environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J9R1X replace ERJ-S02J9R1X in existing designs?

A: Yes. The ERJ-U02J9R1X is electrically and mechanically equivalent to the ERJ-S02J9R1X. Both parts have identical resistance (9.1 Ohms), tolerance (±5%), power rating (0.1W), package dimensions (0402), and operating specifications. The primary difference is packaging format (Tape & Reel versus standard packaging).

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

A: The series designation reflects the base product line within Panasonic's resistor portfolio. Both ERJ-S02 and ERJ-U02 series share identical electrical and mechanical specifications for this 9.1 Ohm 0402 component. The series difference does not affect substitution eligibility.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the ERJ-S02J9R1X and ERJ-U02J9R1X carry AEC-Q200 automotive qualification and anti-sulfur coating, meeting automotive reliability and environmental requirements.

Q: What packaging format should be selected for production?

A: ERJ-U02J9R1X in Tape & Reel (TR) packaging is recommended for automated assembly and high-volume production. ERJ-S02J9R1X in standard packaging is suitable for lower-volume applications or manual assembly processes. Both formats are compatible with standard pick-and-place equipment when appropriate feeders are used.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts have identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling. Standard component storage conditions apply to both parts.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications. Regulatory and compliance status is equivalent across both part numbers.
