Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S12J100U is determined by strict equivalence across the following parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 0.75W
• Package dimensions: 1812 (4532 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive compliance: AEC-Q200
• Termination count: 2
• RoHS and environmental compliance

The ERJ-12YJ100U meets all electrical and mechanical equivalence criteria and is therefore classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S12J100U is the preferred selection for new designs due to its active product status and anti-sulfur coating feature. The ERJ-12YJ100U provides electrical and mechanical equivalence and is suitable for replacement applications where the main part is unavailable. However, the ERJ-12YJ100U carries a "Not For New Designs" status, indicating Panasonic has transitioned this series to end-of-life support.

For new circuit designs, the ERJ-S12J100U should be specified. For existing designs currently using ERJ-12YJ100U, the ERJ-S12J100U offers a direct substitute path with enhanced reliability features and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12YJ100U be used as a direct replacement for ERJ-S12J100U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (10 Ohms ±5%, 0.75W), operate across the same temperature range (-55°C ~ 155°C), and are packaged in the same 1812 (4532 Metric) footprint. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between ERJ-S12J100U and ERJ-12YJ100U?

A: The primary difference is product lifecycle status. ERJ-S12J100U is active and includes anti-sulfur coating. ERJ-12YJ100U is marked "Not For New Designs" and lacks the anti-sulfur feature. All other electrical and mechanical parameters are equivalent.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 1812 (4532 Metric) package with identical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum seated height of 0.028" (0.70mm). PCB layout and assembly processes require no modification.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across -55°C ~ 155°C with ±200ppm/°C temperature coefficient. They are suitable for the same thermal environments.

Q: Are both parts RoHS compliant?

A: Yes. Both ERJ-S12J100U and ERJ-12YJ100U are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no special storage or handling requirements.
