ERJ-S06F1821V Equivalent & Substitute Parts

Part Overview

The ERJ-S06F1821V is a 1.82 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Panasonic Electronic Components. This part features anti-sulfur coating and automotive AEC-Q200 qualification, designed for automotive and industrial applications requiring high reliability in harsh environments. The part is currently active in production with 732 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S06F1821V is determined by strict equivalence across the following parameters:

Resistance value: 1.82 kOhms
Tolerance: ±1%
Power rating: 0.125W (1/8W)
Package: 0805 (2012 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
Automotive qualification: AEC-Q200

Parts meeting all these criteria are direct substitutes. Parts with different power ratings, missing automotive qualification, or non-compliant RoHS status are identified separately and require design review before substitution.

Engineering Selection Recommendations

Direct Equivalents (Full Substitution)

ERJ-6ENF1821V, AC0805FR-071K82L, CRCW08051K82FKEA, and RMCF0805FT1K82 are direct equivalents meeting all electrical, mechanical, and compliance requirements of the ERJ-S06F1821V. All are active production parts with ROHS3 compliance and AEC-Q200 automotive qualification. Selection among these parts is based on supply availability and lead time.

Higher Power Rating Alternative

CRCW08051K82FKEAHP provides 0.5W (1/2W) power rating in the same 0805 package with identical resistance, tolerance, and temperature specifications. This part is suitable for applications requiring higher pulse withstanding capability or thermal margin. Design verification is required to confirm the increased power rating does not introduce thermal management changes.

Compliance Considerations

CRCW08051K82FKTA maintains electrical and mechanical equivalence but carries RoHS non-compliant status and REACH affected designation. This part is restricted for new automotive designs and applications subject to environmental compliance requirements.

RC0805FR-071K82L lacks AEC-Q200 automotive qualification. This part is suitable for non-automotive applications or designs where automotive qualification is not required.

CRCW08051K82FKEB is discontinued at the primary distributor and should not be selected for new designs despite meeting all technical specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute ERJ-S06F1821V with any of the listed parts?

A: Direct substitution is possible with ERJ-6ENF1821V, AC0805FR-071K82L, CRCW08051K82FKEA, and RMCF0805FT1K82. These parts are electrically and mechanically equivalent with matching compliance certifications. CRCW08051K82FKEAHP requires design review due to higher power rating. CRCW08051K82FKTA, RC0805FR-071K82L, and CRCW08051K82FKEB require application-specific evaluation.

Q: What is the difference between the 0.125W and 0.5W versions?

A: CRCW08051K82FKEAHP provides four times the power dissipation capability in the same physical package. The higher power rating enables greater thermal margin and pulse withstanding performance. Electrical characteristics including resistance, tolerance, and temperature coefficient remain identical.

Q: Are all substitute parts automotive qualified?

A: ERJ-6ENF1821V, AC0805FR-071K82L, CRCW08051K82FKEA, CRCW08051K82FKEAHP, and RMCF0805FT1K82 carry AEC-Q200 qualification. RC0805FR-071K82L does not include automotive qualification. CRCW08051K82FKTA and CRCW08051K82FKEB are not suitable for new automotive designs.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. CRCW08051K82FKTA is RoHS non-compliant and restricted for applications subject to environmental regulations.

Q: Can I use RC0805FR-071K82L as a substitute?

A: RC0805FR-071K82L is electrically and mechanically equivalent but lacks AEC-Q200 automotive qualification. Substitution is permissible only in non-automotive applications or where automotive qualification is not a design requirement.

Q: Why is CRCW08051K82FKEB listed if it is discontinued?

A: CRCW08051K82FKEB is documented for reference and historical traceability. Existing inventory may remain available through secondary distributors, but this part should not be selected for new designs due to discontinued status.

Q: Do all parts have the same package dimensions?

A: All listed parts use 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height varies slightly between manufacturers: Panasonic ERJ-S06F1821V and ERJ-6ENF1821V at 0.028" (0.70mm), YAGEO AC0805FR-071K82L and RC0805FR-071K82L at 0.024" (0.60mm), and Vishay Dale and Stackpole parts at 0.020-0.026" (0.50-0.65mm). These variations are within standard PCB assembly tolerances.
