Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF8203U is determined by strict equivalence across the following critical parameters:

• Resistance value: 820 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 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

The ERJ-1TNF8203U qualifies as a direct substitute, meeting all electrical and mechanical parameters. The primary distinction is product status: ERJ-S1TF8203U is Active, while ERJ-1TNF8203U is designated Not For New Designs. Both parts share identical resistance, tolerance, power rating, package dimensions, temperature characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the ERJ-S1TF8203U is the preferred selection due to its Active product status, ensuring long-term availability and manufacturer support. The ERJ-1TNF8203U remains electrically and mechanically equivalent and is suitable for legacy system maintenance, field replacements, or applications where existing inventory is available. Both parts satisfy automotive AEC-Q200 qualification and ROHS3 compliance requirements. Selection between these parts should be based on supply chain availability and design lifecycle requirements rather than electrical performance, as both deliver identical functional characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF8203U be used as a direct replacement for ERJ-S1TF8203U in new designs?

A: Electrically and mechanically, yes. However, ERJ-1TNF8203U carries a "Not For New Designs" status. For new product development, ERJ-S1TF8203U is the recommended choice to ensure long-term supply continuity.

Q: Are there dimensional differences between these parts?

A: No. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.252" L x 0.126" W (6.40mm x 3.20mm) and maximum seated height of 0.028" (0.70mm).

Q: Do both parts meet automotive qualification standards?

A: Yes. Both ERJ-S1TF8203U and ERJ-1TNF8203U are AEC-Q200 qualified and suitable for automotive applications.

Q: What is the significance of the anti-sulfur feature on ERJ-S1TF8203U?

A: The anti-sulfur coating on ERJ-S1TF8203U provides enhanced protection against sulfur-containing environments. ERJ-1TNF8203U does not specify this feature, representing a functional difference in environmental protection capability.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
