Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02J430X is determined by strict equivalence across the following critical parameters:

• Resistance value: 43 Ohms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these parameters. Differences in series designation (ERJ-S02, ERJ-U02, ERJ-2G) reflect manufacturing series variations within Panasonic's product portfolio but do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S02J430X, ERJ-U02J430X, and ERJ-2GEJ430X—are functionally equivalent and interchangeable for applications requiring a 43 Ohm ±5% 0.1W thick film resistor in 0402 package with automotive AEC-Q200 qualification.

Selection between these parts may be based on:

• Inventory availability: ERJ-2GEJ430X has the highest stock level (49,415 units), followed by ERJ-U02J430X (1,124 units) and ERJ-S02J430X (775 units)
• Supply chain lead times and procurement preferences
• Design documentation and qualification history with specific series designations
• Manufacturing facility and traceability requirements

All parts maintain identical electrical performance, thermal characteristics, and compliance certifications. No performance degradation or functional limitation occurs when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J430X be used as a direct replacement for ERJ-S02J430X?

A: Yes. Both parts are 43 Ohm ±5% 0.1W thick film resistors in 0402 package with identical electrical specifications, temperature coefficients, operating temperature ranges, and AEC-Q200 automotive qualification. They are mechanically and electrically interchangeable.

Q: What is the difference between ERJ-S02, ERJ-U02, and ERJ-2G series designations?

A: These designations identify different manufacturing series within Panasonic's resistor portfolio. The series prefix does not affect the electrical or mechanical characteristics of the component. All three series meet the same performance and compliance requirements for this 43 Ohm value.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for the -55°C ~ 155°C operating temperature range required for automotive environments.

Q: Do these parts have the same package dimensions?

A: Yes. All three parts are packaged in 0402 (1005 Metric) with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm).

Q: Are there any RoHS or environmental compliance differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Any of the three parts can be selected for new designs. Selection may be based on current inventory levels, supplier availability, or existing design documentation. All parts provide identical performance and reliability.
