Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F225CS is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (2.2 MOhms), tolerance (±1%), power rating (0.1W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package type (0603/1608 Metric), physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm), and number of terminations (2) must match to ensure PCB footprint compatibility.

Environmental & Compliance: Operating temperature range (-55°C ~ 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH status must align with the original specification.

Composition & Features: Thick film construction is required. Additional features such as moisture resistance and automotive qualification (AEC-Q200) are supplementary attributes that do not disqualify substitution but may indicate enhanced performance characteristics.

All identified substitute parts meet these core criteria. Packaging format (Tape & Reel vs. Cut Tape) represents a logistics variation and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Electrical & Mechanical Equivalence):

RC0603FR-072M2L (YAGEO) qualifies as a direct substitute. All core electrical parameters, mechanical dimensions, and compliance certifications are identical to the RC1608F225CS. This part is Active status with high inventory availability (301,604 units). Packaging format differs (Cut Tape & Digi-Reel vs. Tape & Reel) but does not affect component functionality.

Enhanced Specification Alternatives (Automotive-Qualified):

KTR03EZPF2204 (Rohm Semiconductor), AC0603FR-072M2L (YAGEO), and CRCW06032M20FKEA (Vishay Dale) are all electrically and mechanically equivalent to the RC1608F225CS with the addition of AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability. All three maintain identical electrical specifications, operating temperature range, and RoHS3 compliance. Selection among these three depends on supply chain availability and packaging preference.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. No design-level changes are required when substituting any identified part for the RC1608F225CS in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-072M2L replace RC1608F225CS directly on the PCB?

A: Yes. RC0603FR-072M2L is electrically and mechanically equivalent. Both components share identical resistance (2.2 MOhms), tolerance (±1%), power rating (0.1W), package dimensions (0603/1608 Metric), and operating specifications. The only difference is packaging format (Cut Tape vs. Tape & Reel), which does not affect PCB assembly or performance.

Q: What is the difference between the standard RC1608F225CS and the automotive-qualified alternatives?

A: The RC1608F225CS does not carry AEC-Q200 automotive qualification. KTR03EZPF2204, AC0603FR-072M2L, and CRCW06032M20FKEA all include AEC-Q200 certification, indicating compliance with automotive reliability and testing standards. Electrical and mechanical specifications remain identical across all parts. Automotive-qualified versions are suitable for applications requiring enhanced reliability documentation.

Q: Are there any dimensional differences between substitute parts?

A: Nominal dimensions are equivalent (0.063" L x 0.031" W / 1.60mm x 0.80mm). CRCW06032M20FKEA shows slightly different maximum seated height (0.020" vs. 0.022") and minor dimensional variations (0.061" L x 0.033" W vs. 1.60mm x 0.80mm), but these fall within standard PCB footprint tolerances for 0603 packages and do not affect assembly compatibility.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All identified substitutes, including RC1608F225CS, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns during storage or handling.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-072M2L (YAGEO) has the highest inventory with 301,604 units in stock, followed by CRCW06032M20FKEA (Vishay Dale) with 28,862 units, and AC0603FR-072M2L (YAGEO) with 17,312 units.

Q: Can I use KTR03EZPF2204 in a non-automotive application?

A: Yes. KTR03EZPF2204 is electrically and mechanically equivalent to RC1608F225CS and functions identically in any application. AEC-Q200 qualification is an additional certification that does not restrict use in non-automotive circuits.
