Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S02F2R40X is based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters:

• Resistance value: 2.4 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Temperature coefficient: -100 / +600 ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package format: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 qualification (required for automotive applications)
• Anti-sulfur feature (required for reliability in corrosive environments)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level 1 (required for handling and storage compatibility)

The identified substitute part maintains all electrical specifications, mechanical dimensions, and compliance certifications while differing only in packaging format and manufacturer series designation.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S02F2R40X and ERJ-U02F2R40X are active production components manufactured by Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements:

ERJ-S02F2R40X is suitable for applications requiring standard packaging with 895 pieces currently in inventory.

ERJ-U02F2R40X is suitable for high-volume production environments requiring tape and reel packaging format, with 10,897 pieces currently in inventory. This part is the direct substitute when tape and reel packaging is specified for automated assembly processes.

Both parts maintain full compliance with ROHS3 regulations, AEC-Q200 automotive qualification, and unlimited moisture sensitivity level (MSL 1). The identical electrical performance, temperature characteristics, and anti-sulfur feature ensure functional interchangeability in circuit applications where the 2.4 Ohm ±1% 0.1W 0402 resistor specification is required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F2R40X be used as a direct replacement for ERJ-S02F2R40X?

A: Yes. The ERJ-U02F2R40X is a direct electrical and mechanical substitute. Both parts have identical resistance (2.4 Ohms), tolerance (±1%), power rating (0.1W), package format (0402), temperature characteristics, and compliance certifications. The primary difference is packaging format: ERJ-U02F2R40X is supplied in tape and reel format suitable for automated assembly, while ERJ-S02F2R40X uses standard packaging.

Q: Are there any dimensional differences between these parts?

A: No. Both parts have identical physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). They are fully compatible for PCB layout and assembly.

Q: Do both parts meet automotive specifications?

A: Yes. Both ERJ-S02F2R40X and ERJ-U02F2R40X carry AEC-Q200 automotive qualification and anti-sulfur features, making them suitable for automotive applications requiring reliability in corrosive environments.

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

A: The series designation reflects the packaging format. ERJ-S02 indicates standard packaging, while ERJ-U02 indicates tape and reel packaging. The electrical and mechanical specifications remain identical across both series for this resistance value and package size.

Q: Are both parts RoHS compliant?

A: Yes. Both ERJ-S02F2R40X and ERJ-U02F2R40X are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

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

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