RC1608F8452CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F8452CS is a 84.5 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.1W (1/10W) power dissipation in a 0603 (1608 Metric) surface mount package. This component is classified as Active product status with moisture resistant construction and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications permit the use of functionally identical components from different manufacturers that meet the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F8452CS are classified based on strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 84.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

Substitution Categories:

Direct Substitutes (Functionally Identical): Parts that match all mandatory parameters with identical packaging format (Cut Tape or Tape & Reel).

Upgrade Substitutes: Parts that match all mandatory parameters but are discontinued at primary distributors, suitable only when alternative sourcing is available.

Similar Substitutes (Enhanced Features): Parts that match all mandatory parameters but include additional certifications such as Automotive AEC-Q200 qualification. These parts are electrically and mechanically interchangeable with the primary part and may be used in non-automotive applications without restriction.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Compliance):

RC0603FR-0784K5L (YAGEO) is the recommended primary substitute based on highest inventory availability (738,200 pcs) and active product status. This part meets all mandatory electrical and mechanical parameters identical to the RC1608F8452CS.

CR0603-FX-8452ELF (Bourns Inc.) is an alternative direct substitute with active status and substantial inventory (43,171 pcs), suitable for applications requiring Bourns component qualification.

Secondary Selection (Active Status, Enhanced Certifications):

AC0603FR-0784K5L (YAGEO), CRCW060384K5FKEA (Vishay Dale), ERJ-3EKF8452V (Panasonic), and RMCF0603FT84K5 (Stackpole) are all qualified to Automotive AEC-Q200 standard. These parts are electrically and mechanically interchangeable with the RC1608F8452CS and may be used in non-automotive applications. Selection among these options is based on inventory availability and existing supplier relationships.

Avoid Selection:

MCR03ERTF8452 (Rohm Semiconductor) is discontinued at primary distributors and should be selected only when alternative sourcing channels are established and inventory verification is confirmed.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC0603FR-0784K5L for RC1608F8452CS in my design?

A: Yes. RC0603FR-0784K5L matches all mandatory electrical parameters (84.5 kΩ, ±1%, 0.1W), thermal specifications (±100ppm/°C, -55°C to 155°C), package format (0603), composition (thick film), and compliance certifications (ROHS3, MSL 1). The only difference is packaging format (Tape & Reel versus Cut Tape), which does not affect component performance.

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

A: AEC-Q200 qualification indicates the part meets automotive industry reliability and quality standards. Parts such as AC0603FR-0784K5L, CRCW060384K5FKEA, ERJ-3EKF8452V, and RMCF0603FT84K5 carry this certification. These parts are fully compatible with the RC1608F8452CS in non-automotive applications and may be used as direct substitutes without design modification.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect component performance?

A: No. Packaging format affects only the supply and handling method, not electrical or mechanical performance. Cut Tape and Tape & Reel formats contain identical components. Selection between formats depends on manufacturing process requirements and inventory management practices.

Q: Why is MCR03ERTF8452 listed as discontinued?

A: MCR03ERTF8452 is discontinued at DiGi Electronics, the primary distributor reference. This designation indicates reduced availability through standard distribution channels. Use of this part requires verification of alternative sourcing and inventory confirmation before design implementation.

Q: Are all listed substitutes interchangeable on the PCB?

A: Yes. All listed parts share identical 0603 (1608 Metric) package dimensions and footprint specifications. Physical PCB layout compatibility is guaranteed. Electrical performance is identical across all substitutes due to matching resistance value, tolerance, power rating, and temperature coefficient specifications.

Q: What compliance certifications apply to all listed parts?

A: All parts listed are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). All parts carry EAR99 export classification and HTSUS code 8533.21.0030.
