Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F4020CS are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters:

• Resistance value: 402 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package type: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film
• Moisture resistance: Required

Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status alignment

All substitute parts listed maintain identical electrical specifications and package dimensions. Variations in physical dimensions (length, width, height) within tolerance ranges and packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitution. Parts with AEC-Q200 automotive qualification represent enhanced reliability variants suitable for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (No Functional Difference): RC0603FR-07402RL (YAGEO) provides direct substitution with identical electrical and mechanical specifications. Both components lack AEC-Q200 automotive qualification and share equivalent RoHS3 compliance status.

Automotive-Grade Alternatives (Enhanced Reliability): AC0603FR-07402RL, CRCW0603402RFKEA, ERJ-3EKF4020V, RMCF0603FG402R, and RMCF0603FT402R all include AEC-Q200 automotive qualification. These parts maintain all electrical specifications and operating parameters of the RC1608F4020CS while providing additional reliability validation for automotive applications.

Compliance Consideration: CRCW0603402RFKTA is RoHS non-compliant and REACH-affected. This part is suitable only for applications where RoHS3 compliance is not required.

Packaging Format Selection:

• Tape & Reel format: RC0603FR-07402RL, AC0603FR-07402RL, CRCW0603402RFKTA, ERJ-3EKF4020V, RMCF0603FT402R
• Cut Tape format: CRCW0603402RFKEA, RMCF0603FG402R

Selection between packaging formats depends on assembly process requirements and volume specifications.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07402RL replace RC1608F4020CS in all applications? A: Yes. RC0603FR-07402RL is a direct equivalent with identical resistance value (402 Ohms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and RoHS3 compliance status.

Q: What is the difference between standard and AEC-Q200 qualified parts? A: AEC-Q200 qualification indicates the part has undergone automotive-grade reliability testing and validation. Parts AC0603FR-07402RL, CRCW0603402RFKEA, ERJ-3EKF4020V, RMCF0603FG402R, and RMCF0603FT402R carry this certification. All maintain identical electrical specifications to the base RC1608F4020CS.

Q: Are there dimensional differences between substitute parts? A: Minor dimensional variations exist within tolerance ranges. RC1608F4020CS, RC0603FR-07402RL, ERJ-3EKF4020V measure 0.063" L x 0.031" W. CRCW0603402RFKEA and CRCW0603402RFKTA measure 0.063" L x 0.033" W. RMCF0603FG402R and RMCF0603FT402R measure 0.061" L x 0.031" W. Height variations range from 0.020" to 0.022". These differences do not affect PCB layout or functional performance.

Q: Should I use CRCW0603402RFKTA if RoHS3 compliance is required? A: No. CRCW0603402RFKTA is RoHS non-compliant. Use CRCW0603402RFKEA instead, which provides identical specifications with ROHS3 compliance and AEC-Q200 qualification.

Q: What is Moisture Sensitivity Level (MSL) 1? A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed substitute parts carry MSL 1 rating, matching the RC1608F4020CS specification.

Q: Can I mix packaging formats (Tape & Reel vs. Cut Tape) in production? A: Packaging format selection depends on assembly equipment and process requirements. Electrically and mechanically, all substitute parts are interchangeable regardless of packaging format.

Q: Is temperature coefficient ±100ppm/°C consistent across all substitutes? A: Yes. All substitute parts maintain the ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range specified for RC1608F4020CS.
