Engineering Selection Recommendations

For Active Product Status Applications:

The following parts are recommended as direct substitutes with Active product status:

RC1206FR-071K82L (YAGEO): Active status, standard industrial grade, compact dimensions (3.10 x 1.60 mm), lowest seated height (0.65 mm). Suitable for space-constrained PCB layouts.
CR1206-FX-1821ELF (Bourns Inc.): Active status, standard industrial grade, standard dimensions (3.20 x 1.60 mm). Highest seated height (0.75 mm) among active parts.
CRCW12061K82FKEA (Vishay Dale): Active status with AEC-Q200 automotive qualification, standard dimensions (3.20 x 1.60 mm), lowest seated height (0.60 mm). Suitable for automotive and high-reliability applications.
RMCF1206FT1K82 (Stackpole Electronics Inc): Active status with AEC-Q200 automotive qualification, standard dimensions (3.20 x 1.60 mm), seated height (0.70 mm). Suitable for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q1: Can I substitute RC3216F1821CS with any 1.82 kOhm resistor in 1206 package?

A: No. Substitution requires exact matching of all critical parameters: 1.82 kOhms resistance, ±1% tolerance, 0.25W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, thick film composition, 2 terminations, MSL 1 moisture sensitivity, and ROHS3 compliance. Dimensional variations (length, width, height) are acceptable within the 1206 package specification, but all electrical and environmental parameters must match exactly.

Q2: What is the difference between standard industrial grade and AEC-Q200 automotive grade substitutes?

A: AEC-Q200 automotive-qualified parts (AC1206FR-071K82L, CRCW12061K82FKEA, RMCF1206FT1K82) undergo additional qualification testing for automotive applications including thermal cycling, vibration, and reliability assessments. The RC3216F1821CS is standard industrial grade without automotive qualification. Use AEC-Q200 parts only when automotive-grade reliability is required by application specifications.

Q3: Are there dimensional differences between substitute parts that affect PCB layout?

A: Yes. While all parts conform to 1206 package specification, seated heights vary: RC3216F1821CS (0.66 mm), CR1206-FX-1821ELF (0.75 mm), RC1206FR-071K82L (0.65 mm), AC1206FR-071K82L (0.65 mm), CRCW12061K82FKEA (0.60 mm), ERJ-8ENF1821V (0.70 mm), MCR18ERTF1821 (0.65 mm), RMCF1206FT1K82 (0.70 mm). Length and width also vary slightly (3.05-3.20 mm length, 1.55-1.60 mm width). Verify PCB clearances and solder reflow profiles accommodate the selected substitute's physical dimensions.

Q4: Why is ERJ-8ENF1821V marked "Not For New Designs"?

A: "Not For New Designs" status indicates the manufacturer has discontinued active development and recommends against using this part in new product designs. It remains available for existing inventory and legacy system support only. For new designs, select from Active status parts: RC1206FR-071K82L, CR1206-FX-1821ELF, AC1206FR-071K82L, CRCW12061K82FKEA, or RMCF1206FT1K82.

Q5: Is MCR18ERTF1821 a viable substitute despite being discontinued?

A: MCR18ERTF1821 is discontinued at DiGi Electronics and should not be specified for new designs or long-term production. Use only when existing inventory is available and no alternative meets project constraints. For ongoing production, select from Active status alternatives.

Q6: Do all substitute parts meet ROHS3 and REACH compliance?

A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected, matching the RC3216F1821CS compliance profile. This ensures regulatory compliance across all substitutes for applications requiring environmental and hazardous substance restrictions.

Q7: What packaging formats are available for these substitutes?

A: Packaging formats vary by manufacturer: CR1206-FX-1821ELF (Tape & Reel), RC1206FR-071K82L (Tape & Reel), AC1206FR-071K82L (Tape & Reel), CRCW12061K82FKEA (Cut Tape & Digi-Reel), ERJ-8ENF1821V (Tape & Reel), MCR18ERTF1821 (Cut Tape & Digi-Reel), RMCF1206FT1K82 (Tape & Reel). Verify packaging compatibility with your procurement and assembly processes.
