Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02J684X is determined by strict equivalence across the following critical parameters:

• Resistance value: 680 kOhms
• 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
• AEC-Q200 automotive qualification
• RoHS3 compliance
• Moisture sensitivity level: 1

All substitute parts listed below meet these parameters without exception. Substitution is based on functional and mechanical interchangeability within the same package footprint and electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—ERJ-S02J684X, ERJ-U02J684X, and ERJ-2GEJ684X—are functionally equivalent and directly interchangeable. Selection between these parts should be based on:

Availability and Lead Time: ERJ-2GEJ684X has the highest inventory level (194,327 units), followed by ERJ-U02J684X (5,034 units), and ERJ-S02J684X (642 units). For applications requiring immediate procurement or high-volume orders, ERJ-2GEJ684X is the preferred choice.

Compliance and Certification: All three parts maintain identical AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. No compliance advantage exists between the alternatives.

Series Designation: The parts belong to different Panasonic series (ERJ-S02, ERJ-U02, and ERJ-2G respectively). Series designation reflects internal Panasonic product line organization and does not affect electrical or mechanical performance.

Feature Parity: ERJ-S02J684X and ERJ-U02J684X both include anti-sulfur coating. ERJ-2GEJ684X does not specify anti-sulfur coating in its feature set. For applications in sulfur-rich environments, ERJ-S02J684X or ERJ-U02J684X are preferred.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J684X be used as a direct replacement for ERJ-S02J684X?

A: Yes. Both parts share identical electrical specifications (680 kOhms ±5%, 0.1W), package (0402), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Both include anti-sulfur coating. Footprint and solder reflow profiles are identical.

Q: What is the difference between ERJ-2GEJ684X and ERJ-S02J684X?

A: The parts are electrically and mechanically equivalent across all critical parameters. The primary difference is that ERJ-S02J684X specifies anti-sulfur coating while ERJ-2GEJ684X does not. Both maintain AEC-Q200 qualification and identical performance characteristics. ERJ-2GEJ684X has significantly higher inventory availability.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. All are suitable for automotive circuit applications within the specified operating temperature range of -55°C ~ 155°C.

Q: Does package compatibility differ between these part numbers?

A: No. All three parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm). PCB footprints and assembly processes are identical.

Q: Which part should be selected for new designs?

A: Selection should prioritize availability and supply chain stability. ERJ-2GEJ684X is recommended for new designs due to high inventory levels and active production status. If anti-sulfur coating is a design requirement, ERJ-S02J684X or ERJ-U02J684X are appropriate alternatives.

Q: Are there any moisture sensitivity concerns with these parts?

A: No. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices are sufficient.
