ERJ-S02J3R0X Equivalent & Substitute Parts

Part Overview

The ERJ-S02J3R0X is a 3 Ohm ±5% 0.1W (1/10W) chip resistor manufactured by Panasonic Electronic Components in the 0402 (1005 Metric) package format. This thick film resistor features anti-sulfur properties and automotive AEC-Q200 qualification, making it suitable for automotive and harsh environment applications. The part is currently in active production status with 803 pieces available in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required but alternative packaging configurations or series designations are acceptable for system integration.

Substitute Part Grouping Explanation

Substitution of the ERJ-S02J3R0X is based on electrical and mechanical parameter equivalence. The primary substitute identified is the ERJ-U02J3R0X, which maintains identical electrical specifications including resistance value (3 Ohms), tolerance (±5%), power rating (0.1W), and package format (0402 / 1005 Metric). Both parts share the same composition (thick film), anti-sulfur feature set, automotive AEC-Q200 qualification, temperature coefficient (-100 / +600 ppm/°C), and operating temperature range (-55°C ~ 155°C). The key differentiator between these parts is the series designation (ERJ-S02 versus ERJ-U02) and packaging configuration (standard packaging versus Tape & Reel). Substitution is valid when these packaging and series variations are acceptable within the application context.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02J3R0X and ERJ-U02J3R0X are active production parts manufactured by Panasonic Electronic Components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by packaging requirements and supply chain availability. The ERJ-S02J3R0X is suitable for applications requiring standard packaging with current inventory of 803 pieces. The ERJ-U02J3R0X provides equivalent electrical and mechanical performance in Tape & Reel packaging format with higher inventory availability (5360 pieces), making it appropriate for high-volume production environments or when tape and reel handling is required. Both parts satisfy automotive AEC-Q200 qualification requirements and maintain identical electrical performance across the specified operating temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J3R0X replace ERJ-S02J3R0X in existing designs?

A: Yes. The ERJ-U02J3R0X provides identical electrical specifications (3 Ohms ±5%, 0.1W), mechanical dimensions (0402 / 1005 Metric), and performance characteristics. The primary difference is packaging format (Tape & Reel versus standard packaging). Substitution is valid when the receiving system can accommodate tape and reel component handling.

Q: Are there differences in reliability or performance between these parts?

A: No. Both parts share identical composition (thick film), anti-sulfur features, AEC-Q200 automotive qualification, temperature coefficient (-100 / +600 ppm/°C), and operating temperature range (-55°C ~ 155°C). Performance and reliability characteristics are equivalent.

Q: What is the significance of the series designation change (ERJ-S02 to ERJ-U02)?

A: The series designation reflects the base product number classification within Panasonic's product line. This designation does not affect electrical or mechanical compatibility. Both series maintain the same 0402 package format and electrical specifications for the 3 Ohm ±5% 0.1W resistor.

Q: How does packaging configuration affect component selection?

A: The ERJ-S02J3R0X uses standard packaging suitable for manual handling and smaller quantity orders. The ERJ-U02J3R0X uses Tape & Reel (TR) packaging optimized for automated assembly equipment and high-volume production. Selection depends on manufacturing process requirements and handling capabilities.

Q: Are both parts compliant with automotive standards?

A: Yes. Both the ERJ-S02J3R0X and ERJ-U02J3R0X carry AEC-Q200 automotive qualification and are ROHS3 compliant with REACH unaffected status, making them suitable for automotive and regulated applications.

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

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. Standard storage conditions are acceptable for both the ERJ-S02J3R0X and ERJ-U02J3R0X.
