Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F4020CS are qualified based on the following critical parameters that determine functional equivalence:

Electrical Parameters (Must Match Exactly):

• Resistance value: 402 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) nominal

Environmental & Compliance Parameters:

• Composition: Thick Film
• Features: Moisture Resistant
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria. Two substitute parts (CRCW1206402RFKEA and ERJ-8ENF4020V) include additional Automotive AEC-Q200 qualification, which represents an enhanced specification level suitable for automotive applications while maintaining full compatibility with standard industrial designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Industrial):

• RC1206FR-07402RL (YAGEO): Active product status with highest inventory availability (276,264 pieces). Suitable for standard industrial applications requiring 402 Ohm 1% 1/4W 1206 resistors. Meets all electrical and mechanical specifications with ROHS3 compliance.
• CR1206-FX-4020ELF (Bourns): Active product status with 27,593 pieces in stock. Functionally equivalent with identical electrical parameters and ROHS3 compliance.

Secondary Selection (Enhanced Automotive Qualification):

• CRCW1206402RFKEA (Vishay Dale): Active product status with AEC-Q200 automotive qualification. Suitable for applications requiring automotive-grade reliability. 21,579 pieces in stock.

Not Recommended for New Designs:

• ERJ-8ENF4020V (Panasonic): Product status is "Not For New Designs." While electrically and mechanically equivalent with AEC-Q200 qualification, this part should not be selected for new circuit designs due to its obsolescence trajectory.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F4020CS with any of the listed parts in existing designs?

A: Yes. All listed substitute parts except ERJ-8ENF4020V are functionally equivalent for direct substitution. They share identical electrical specifications (402 Ohms ±1%, 0.25W), mechanical package (1206), and environmental ratings. ERJ-8ENF4020V is electrically equivalent but marked "Not For New Designs" and should only be used if existing inventory must be consumed.

Q: What is the difference between standard and AEC-Q200 qualified parts?

A: CRCW1206402RFKEA and ERJ-8ENF4020V include AEC-Q200 automotive qualification, indicating enhanced reliability testing and qualification for automotive applications. Standard parts (RC3216F4020CS, CR1206-FX-4020ELF, RC1206FR-07402RL) are suitable for industrial and commercial applications. AEC-Q200 parts are backward compatible with standard applications.

Q: Are there dimensional differences between substitute parts?

A: All parts use the 1206 (3216 Metric) package with nominal dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). Maximum seated heights vary slightly: RC3216F4020CS (0.66mm), CR1206-FX-4020ELF (0.75mm), RC1206FR-07402RL (0.65mm), CRCW1206402RFKEA (0.60mm), and ERJ-8ENF4020V (0.70mm). These variations are within standard PCB assembly tolerances and do not affect functional compatibility.

Q: Which substitute part has the best availability?

A: RC1206FR-07402RL (YAGEO) offers the highest inventory with 276,264 pieces in stock, followed by ERJ-8ENF4020V (Panasonic) with 122,325 pieces. For new designs, RC1206FR-07402RL is the recommended choice based on active status and availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial electronics manufacturing.
