Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF9092U is determined by strict equivalence across the following critical parameters:

• Resistance value: 90.9 kOhms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The ERJ-12SF9092U meets all electrical and mechanical specifications required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, thermal characteristics, and compliance certifications. The primary distinction is the product lifecycle status: ERJ-S1DF9092U is active for new designs, while ERJ-12SF9092U is designated as not for new designs but remains functionally equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-12SF9092U is electrically and mechanically equivalent to the ERJ-S1DF9092U and is suitable for direct substitution in applications where the main part is unavailable. Both parts carry identical AEC-Q200 automotive qualification and ROHS3 compliance, ensuring compatibility with automotive and industrial applications requiring these certifications.

For new design implementations, the ERJ-S1DF9092U is the preferred selection due to its active product status. The ERJ-12SF9092U may be used in existing designs or where inventory availability of the primary part is constrained, as it maintains full electrical and mechanical compatibility with no performance degradation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF9092U be used as a direct replacement for ERJ-S1DF9092U?

A: Yes. Both parts are identical in resistance (90.9 kOhms), tolerance (±1%), power rating (0.75W), package (2010), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), and automotive qualifications (AEC-Q200). The only difference is product lifecycle status.

Q: What does "Not For New Designs" mean for the ERJ-12SF9092U?

A: This designation indicates that Panasonic has transitioned this part to legacy status and recommends using the ERJ-S1DF9092U for new product development. However, the ERJ-12SF9092U remains fully functional and compliant for use in existing designs or as a substitute when the primary part is unavailable.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.197" L x 0.098" W (5.00mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable in PCB layouts designed for the 2010 (5025 Metric) package.

Q: Do both parts meet automotive standards?

A: Yes. Both ERJ-S1DF9092U and ERJ-12SF9092U carry AEC-Q200 qualification and are suitable for automotive applications. Both are ROHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the difference in available inventory?

A: ERJ-S1DF9092U has 1,055 pieces in stock, while ERJ-12SF9092U has 15,199 pieces available. Inventory levels may influence substitution decisions based on supply requirements and lead time considerations.
