ERJ-S1DF6812U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF6812U is a 68.1 kOhms ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. Manufactured by Panasonic Electronic Components, this resistor features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications. The part is currently in active production status with 1073 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits equivalent alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF6812U is determined by strict equivalence across the following parameters:

• Resistance value: 68.1 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 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

All identified substitute parts meet these criteria. Substitutes are grouped by manufacturer and product status to facilitate selection based on availability and design phase requirements.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1DF6812U (Panasonic, Active status) is the primary selection. This part maintains active production status and includes anti-sulfur coating, providing enhanced reliability in corrosive environments.

The ERJ-12SF6812U (Panasonic, Not For New Designs) is electrically and mechanically equivalent but carries a legacy product status designation. This part is suitable only for sustaining production of existing designs or as a temporary substitute when primary parts are unavailable.

The CRCW201068K1FKEF (Vishay Dale, Active status) is a cross-manufacturer equivalent from an alternative qualified supplier. This part is suitable for new designs and provides supply diversification. Selection between Panasonic and Vishay alternatives depends on established supplier relationships and procurement strategy.

All three parts satisfy automotive AEC-Q200 qualification and ROHS3 compliance requirements, making them interchangeable from a regulatory and environmental standpoint.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF6812U be used in new designs? A: The ERJ-12SF6812U carries a "Not For New Designs" status. While electrically and mechanically equivalent, it is designated for sustaining production only. New designs should specify either ERJ-S1DF6812U or CRCW201068K1FKEF.

Q: Are all substitute parts physically identical? A: Yes. All parts share the same 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). They are pin-compatible and footprint-compatible.

Q: Do substitute parts meet automotive requirements? A: Yes. All listed substitutes carry AEC-Q200 automotive qualification and operate across the same temperature range (-55°C ~ 155°C). They are suitable for automotive applications.

Q: What is the difference between ERJ-S1DF6812U and ERJ-12SF6812U? A: Both are Panasonic products with identical electrical specifications. The primary difference is product status: ERJ-S1DF6812U is Active, while ERJ-12SF6812U is Not For New Designs. The ERJ-S1DF6812U also includes anti-sulfur coating.

Q: Can I mix manufacturers in the same assembly? A: Yes. All parts meet identical electrical, mechanical, and compliance specifications. Mixing Panasonic and Vishay parts in the same assembly is permissible from an engineering standpoint. Procurement and supply chain considerations may apply.

Q: What does MSL 1 (Unlimited) mean? A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life and require no special moisture control during storage or handling.
