Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RCS2012F82R5CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 82.5 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.125W / 1/8W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package / Case: 0805 (2012 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (preferred)
• REACH Status: REACH Unaffected (preferred)

All identified substitute parts meet the electrical and mechanical equivalence criteria. Variations in physical dimensions (height, length, width) within standard tolerances do not affect substitution validity. Differences in features (automotive AEC-Q200 certification, anti-sulfur coating, moisture resistance) represent enhanced or alternative specifications that do not prevent substitution but may indicate suitability for specific application environments.

Parameter Comparison

Engineering Selection Recommendations

All six parts listed meet the core electrical and mechanical substitution criteria for the RCS2012F82R5CS. Selection among these equivalents is based on compliance status and application requirements:

ROHS3 Compliant & REACH Unaffected (Preferred for regulated applications):

• CRCW080582R5FKEA (Vishay Dale)
• ERJ-6ENF82R5V (Panasonic Electronic Components)
• RC0805FR-0782R5L (YAGEO)
• RMCF0805FT82R5 (Stackpole Electronics Inc)

Compliance Restrictions:

• CRCW080582R5FKTA (Vishay Dale) is RoHS non-compliant and REACH Affected. This part is suitable only for applications where RoHS3 compliance is not required.

Automotive Applications: Parts with AEC-Q200 automotive qualification are available: CRCW080582R5FKEA, CRCW080582R5FKTA, ERJ-6ENF82R5V, and RMCF0805FT82R5. These are suitable for automotive circuit applications where AEC-Q200 certification is specified.

Standard Industrial Applications: All parts are suitable for standard industrial applications. RC0805FR-0782R5L (YAGEO) and RC0805FR-0782R5L provide moisture-resistant construction without automotive qualification, appropriate for general-purpose industrial use.

Frequently Asked Questions (FAQ)

Q: Can CRCW080582R5FKTA be used as a direct substitute for RCS2012F82R5CS?

A: CRCW080582R5FKTA meets all electrical and mechanical equivalence criteria. However, it is RoHS non-compliant and REACH Affected. Use this part only in applications where RoHS3 compliance is not a requirement.

Q: What is the difference between the two Vishay Dale parts (CRCW080582R5FKEA and CRCW080582R5FKTA)?

A: Both parts are electrically and mechanically identical 82.5 Ohm ±1% 0805 resistors with AEC-Q200 automotive qualification. The primary difference is compliance status: CRCW080582R5FKEA is ROHS3 Compliant and REACH Unaffected, while CRCW080582R5FKTA is RoHS non-compliant and REACH Affected.

Q: Are there packaging differences between these substitute parts?

A: Most substitute parts are supplied in Tape & Reel (TR) packaging. ERJ-6ENF82R5V (Panasonic) is supplied in Cut Tape (CT) & Digi-Reel® format. All packaging formats are compatible with standard SMD assembly equipment.

Q: Which substitute part has the lowest profile?

A: CRCW080582R5FKEA (Vishay Dale) has the lowest seated height at 0.020" (0.50mm). RC0805FR-0782R5L (YAGEO) has 0.024" (0.60mm), RCS2012F82R5CS has 0.026" (0.66mm), RMCF0805FT82R5 has 0.026" (0.65mm), and ERJ-6ENF82R5V has 0.028" (0.70mm). Height differences are within standard tolerances and do not affect functional substitution.

Q: Can I substitute based on automotive AEC-Q200 certification?

A: AEC-Q200 certification is an enhanced feature, not a substitution requirement. Parts with AEC-Q200 (CRCW080582R5FKEA, CRCW080582R5FKTA, ERJ-6ENF82R5V, RMCF0805FT82R5) are suitable for automotive applications. Parts without AEC-Q200 (RC0805FR-0782R5L) are still electrically and mechanically equivalent and can be used in non-automotive applications.

Q: What inventory levels are available for each substitute?

A: Current inventory: RCS2012F82R5CS (1,078 pcs), CRCW080582R5FKEA (30,200 pcs), CRCW080582R5FKTA (4,572 pcs), ERJ-6ENF82R5V (107,497 pcs), RC0805FR-0782R5L (116,566 pcs), RMCF0805FT82R5 (4,102 pcs).

Q: Are all these parts suitable for the full -55°C to 155°C temperature range?

A: Yes. All substitute parts are rated for -55°C to 155°C operating temperature range with ±100ppm/°C temperature coefficient, matching the RCS2012F82R5CS specification.
