RC1608F28R0CS Equivalent & Substitute Parts

Part Overview

The RC1608F28R0CS is a 28 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format with 0.1W power rating. This component is classified as Active product status with moisture-resistant construction and unlimited moisture sensitivity level (MSL 1). The part is RoHS3 compliant and REACH unaffected, suitable for general industrial and consumer applications requiring precision resistive elements in compact surface-mount form factors.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative sourcing improves supply chain resilience, or when design requirements necessitate components with enhanced certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F28R0CS is determined by strict equivalence across the following mandatory parameters:

Mandatory Matching Parameters:

• Resistance value: 28 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 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)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 (exact match required)

Allowable Variations:

• Manufacturer identity (different suppliers acceptable)
• Packaging format (Tape & Reel or Cut Tape acceptable)
• Product status (Active or Discontinued acceptable for existing inventory)
• Physical dimensions within tolerance (minor variations in length/width/height acceptable if package designation remains 0603)
• Additional certifications (AEC-Q200 automotive qualification is additive, not restrictive)
• Moisture sensitivity level (MSL 1 is baseline; no higher MSL acceptable)

All substitute parts listed below meet these criteria and are direct functional equivalents suitable for drop-in replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Equivalent: RC0603FR-0728RL (YAGEO) is the recommended primary substitute. This part maintains identical electrical specifications, Active product status, and standard Tape & Reel packaging. High inventory availability (58,382 pcs) ensures supply continuity.

Secondary Direct Equivalent: RMCF0603FT28R0 (Stackpole Electronics Inc) provides direct functional equivalence with Active product status. This part includes AEC-Q200 automotive qualification, which is beneficial for applications requiring enhanced reliability standards without introducing incompatibility. Inventory level is adequate at 1,391 pcs.

Automotive-Grade Alternatives: CRCW060328R0FKEA (Vishay Dale) and ERJ-3EKF28R0V (Panasonic Electronic Components) both provide AEC-Q200 automotive qualification while maintaining all core electrical parameters. These parts are suitable for designs requiring automotive-grade components. Inventory levels are robust (24,760 pcs and 48,930 pcs respectively).

Discontinued Part: MCR03ERTF28R0 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics but maintains full electrical equivalence. This part should be selected only when existing inventory is available and future replenishment is not required.

All substitute parts are RoHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications as the primary part.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0728RL replace RC1608F28R0CS in existing designs? A: Yes. RC0603FR-0728RL is a direct functional equivalent with identical resistance (28 Ohms), tolerance (±1%), power rating (0.1W), package (0603), composition (Thick Film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance status (ROHS3). No circuit redesign is required.

Q: What is the difference between the standard RC1608F28R0CS and the AEC-Q200 qualified alternatives? A: The RC1608F28R0CS is a general-purpose industrial component. CRCW060328R0FKEA, ERJ-3EKF28R0V, and RMCF0603FT28R0 include AEC-Q200 automotive qualification, indicating enhanced reliability testing and quality assurance per automotive standards. All electrical parameters remain identical. AEC-Q200 qualification is additive and does not restrict use in non-automotive applications.

Q: Are there any physical dimension differences between these parts? A: Minor variations exist within the 0603 package specification. RC1608F28R0CS, RC0603FR-0728RL, and ERJ-3EKF28R0V share identical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm). CRCW060328R0FKEA and RMCF0603FT28R0 have slightly different length specifications (0.061" / 1.55mm) but remain within 0603 package tolerance. Height variations are negligible (0.020" to 0.022"). These differences do not affect PCB footprint compatibility.

Q: Which substitute part has the best inventory availability? A: RC0603FR-0728RL (YAGEO) offers the highest inventory level at 58,382 pcs. ERJ-3EKF28R0V (Panasonic) provides 48,930 pcs. Both ensure reliable supply for high-volume production requirements.

Q: Can MCR03ERTF28R0 be used as a long-term replacement? A: MCR03ERTF28R0 is electrically equivalent but is Discontinued at DiGi Electronics. This part should be used only when existing inventory is available and future replenishment is not a requirement. For new designs or long-term production, select from Active status parts: RC0603FR-0728RL, CRCW060328R0FKEA, ERJ-3EKF28R0V, or RMCF0603FT28R0.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect substitution? A: Packaging format affects handling, storage, and automated assembly processes but does not affect electrical performance or circuit compatibility. RC1608F28R0CS and most substitutes use Tape & Reel (TR) format. MCR03ERTF28R0 uses Cut Tape (CT) & Digi-Reel®. Selection should be based on assembly equipment compatibility and inventory management requirements.

Q: Are all these parts RoHS3 compliant? A: Yes. All listed parts—RC1608F28R0CS, RC0603FR-0728RL, MCR03ERTF28R0, CRCW060328R0FKEA, ERJ-3EKF28R0V, and RMCF0603FT28R0—are ROHS3 compliant and REACH unaffected. They are suitable for applications subject to RoHS and REACH regulations.

Q: What is the moisture sensitivity level (MSL) for these parts? A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture-controlled storage or baking procedures prior to soldering.
