RC1608F1054CS Equivalent & Substitute Parts

Part Overview

The RC1608F1054CS is a 1.05 MOhm ±1% thick film chip resistor in 0603 (1608 Metric) package rated for 0.1W power dissipation. Manufactured by Samsung Electro-Mechanics, this component is actively produced and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts become necessary when the primary manufacturer's inventory is unavailable, when supply chain optimization is required, or when design flexibility permits equivalent alternatives from qualified manufacturers.

Substitute Part Grouping Explanation

Equivalent substitution for the RC1608F1054CS is determined by strict alignment of electrical and mechanical parameters. All substitute parts must match the following criteria:

• Resistance value: 1.05 MOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Two substitute parts meet these criteria. RC0603FR-071M05L from YAGEO is a direct electrical and mechanical equivalent. CRCW06031M05FKEA from Vishay Dale is functionally equivalent with minor dimensional variations and includes automotive AEC-Q200 qualification, which represents an enhanced specification level rather than a limitation.

Parameter Comparison

Engineering Selection Recommendations

RC0603FR-071M05L from YAGEO provides direct substitution with identical electrical specifications and mechanical dimensions. Both the Samsung and YAGEO parts are actively produced with ROHS3 compliance and unlimited moisture sensitivity rating.

CRCW06031M05FKEA from Vishay Dale is functionally equivalent with automotive AEC-Q200 qualification. Minor dimensional variations exist: length is 0.002" shorter (1.55mm vs 1.60mm), width is 0.002" wider (0.85mm vs 0.80mm), and seated height is 0.002" lower (0.50mm vs 0.55mm). These variations remain within typical PCB layout tolerances for 0603 package designs. The AEC-Q200 rating indicates enhanced reliability qualification for automotive applications and does not restrict use in non-automotive designs.

Selection between these substitutes depends on supply availability and application requirements. All three parts maintain identical electrical performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M05L replace RC1608F1054CS directly?

A: Yes. RC0603FR-071M05L matches all electrical parameters (1.05 MOhms ±1%, 0.1W, ±100ppm/°C) and mechanical dimensions (0603 package, 0.063" x 0.031" x 0.022" max height). No design modifications are required.

Q: What are the dimensional differences with CRCW06031M05FKEA?

A: CRCW06031M05FKEA has minor dimensional variations: 0.002" shorter length (1.55mm), 0.002" wider width (0.85mm), and 0.002" lower seated height (0.50mm). These differences are within standard 0603 package tolerances and do not affect PCB layout compatibility for typical applications.

Q: Does AEC-Q200 qualification on CRCW06031M05FKEA restrict its use?

A: No. AEC-Q200 is an automotive reliability standard that represents enhanced qualification. Parts meeting AEC-Q200 are suitable for all applications, including non-automotive designs.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC1608F1054CS, RC0603FR-071M05L, and CRCW06031M05FKEA are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity).

Q: What determines substitution eligibility for this resistor?

A: Substitution eligibility is determined by matching resistance value (1.05 MOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and regulatory compliance (ROHS3, MSL 1).
