Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F82R5CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

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

Mechanical Parameters (Must Match Exactly):

Package type: 0805 (2012 Metric)
Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs and Replacements):

RC0805FR-0782R5L (YAGEO), CRCW080582R5FKEA (Vishay Dale), ERJ-6ENF82R5V (Panasonic Electronic Components), and RMCF0805FT82R5 (Stackpole Electronics Inc) are fully qualified substitutes. All four parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status. These parts are electrically and mechanically identical to the RC2012F82R5CS and are suitable for direct replacement in production environments.

Conditional Substitute (Compliance Restrictions Apply):

CRCW080582R5FKTA (Vishay Dale) is electrically and mechanically equivalent but carries RoHS non-compliant and REACH Affected designations. This part is restricted for use in applications or regions requiring RoHS3 compliance or REACH compliance. Selection of this part requires explicit design approval and compliance verification.

Inventory and Availability Considerations:

RC0805FR-0782R5L maintains the highest inventory level (116,566 pcs), followed by ERJ-6ENF82R5V (107,497 pcs). CRCW080582R5FKTA and RMCF0805FT82R5 have lower inventory levels (4,572 pcs and 4,102 pcs respectively). Packaging format differs for ERJ-6ENF82R5V (Cut Tape & Digi-Reel) versus all other parts (Tape & Reel), which may affect automated assembly line compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0782R5L be used as a direct replacement for RC2012F82R5CS?

A: Yes. RC0805FR-0782R5L is a direct electrical and mechanical equivalent. Both parts share identical resistance (82.5 Ω), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 0805 package format. The seated height difference (0.60mm vs. 0.66mm) does not affect PCB assembly or circuit performance.

Q: What is the difference between CRCW080582R5FKEA and CRCW080582R5FKTA?

A: Both parts are electrically and mechanically identical with 82.5 Ω resistance, ±1% tolerance, and 0.125W power rating in 0805 package. The primary difference is compliance status: CRCW080582R5FKEA is ROHS3 Compliant and REACH Unaffected, while CRCW080582R5FKTA is RoHS non-compliant and REACH Affected. Selection depends on regulatory requirements for the end application.

Q: Why does ERJ-6ENF82R5V have different packaging (Cut Tape & Digi-Reel) compared to other substitutes?

A: ERJ-6ENF82R5V is supplied in Cut Tape and Digi-Reel format by Panasonic, while most other substitutes use standard Tape & Reel packaging. This packaging difference does not affect electrical performance but may require different handling procedures during automated assembly. Verify compatibility with your assembly equipment before selection.

Q: Are all substitute parts rated for automotive applications?

A: CRCW080582R5FKEA, CRCW080582R5FKTA, ERJ-6ENF82R5V, and RMCF0805FT82R5 carry AEC-Q200 automotive qualification ratings. RC0805FR-0782R5L and RC2012F82R5CS do not carry explicit AEC-Q200 designation. For automotive applications, select from the AEC-Q200 qualified parts.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. All listed parts, including the main part RC2012F82R5CS, carry MSL 1 rating, meaning they do not require special moisture-controlled storage or baking procedures prior to assembly. This simplifies inventory management and reduces handling complexity.

Q: Can I use CRCW080582R5FKTA in a design requiring RoHS compliance?

A: No. CRCW080582R5FKTA is marked as RoHS non-compliant and REACH Affected. For designs requiring RoHS3 compliance, select RC0805FR-0782R5L, CRCW080582R5FKEA, ERJ-6ENF82R5V, or RMCF0805FT82R5 instead.

Q: Are there any height restrictions that would prevent substitution?

A: No. Seated height variations among substitutes range from 0.50mm to 0.70mm, all within acceptable tolerances for standard 0805 package PCB assembly. These minor height differences do not affect circuit functionality or assembly compatibility.
