Substitute Part Grouping Explanation

Substitution of the ERJ-S02F4R30X is permissible with parts that maintain identical electrical specifications and mechanical compatibility. The critical parameters governing substitution are:

• Resistance Value: 4.3 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package Format: 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)

The ERJ-U02F4R30X qualifies as a direct substitute based on identical electrical performance, mechanical dimensions, thermal characteristics, and automotive compliance ratings. The primary distinction between these parts is the series designation (ERJ-S02 versus ERJ-U02) and packaging format (bulk versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The ERJ-U02F4R30X is a direct functional equivalent to the ERJ-S02F4R30X. Both components are manufactured by Panasonic Electronic Components and share identical electrical specifications, mechanical dimensions, thermal performance characteristics, and automotive compliance certifications. The parts are interchangeable from an electrical and mechanical standpoint.

The primary distinction between these parts is packaging format. The ERJ-S02F4R30X is supplied in bulk packaging, while the ERJ-U02F4R30X is supplied in Tape & Reel (TR) format. Selection between these parts should be based on assembly process requirements and inventory management practices. Both parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U02F4R30X be used as a direct replacement for the ERJ-S02F4R30X?

A: Yes. Both parts are electrically and mechanically identical. They share the same 4.3 Ohm resistance value, ±1% tolerance, 0.1W power rating, 0402 package format, and automotive AEC-Q200 qualification. The only difference is packaging format (bulk versus Tape & Reel).

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

A: The series designation reflects the manufacturing series within Panasonic's product line. Both series produce identical electrical and mechanical specifications for this 4.3 Ohm resistor value. The series difference does not affect functional performance or compatibility.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C ~ 155°C), share the same temperature coefficient (-100 / +600 ppm/°C), and deliver identical electrical performance under all operating conditions.

Q: Which packaging format should be selected for high-volume assembly?

A: Tape & Reel (TR) packaging, represented by the ERJ-U02F4R30X, is standard for automated pick-and-place assembly operations. Bulk packaging is suitable for manual assembly or lower-volume applications.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both the ERJ-S02F4R30X and ERJ-U02F4R30X carry AEC-Q200 automotive qualification and anti-sulfur construction, making them suitable for automotive applications requiring reliability and environmental resistance.

Q: Are there any RoHS or environmental compliance differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental compliance certifications.
