RC1608F28R7CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F28R7CS is a 28.7 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 full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is designed for general industrial applications requiring moisture-resistant thick film construction across an operating temperature range of -55°C to 155°C.

Equivalent and substitute parts are necessary when the original manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative qualified sources meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F28R7CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 28.7 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package designation: 0603 (1608 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture sensitivity level: MSL 1 (Unlimited)

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• REACH Unaffected status
• Packaging format: Tape & Reel (TR)

All substitute parts listed below meet these criteria without exception. Dimensional variations within supplier tolerances (height-seated maximum and length/width within ±0.05mm) do not affect substitution eligibility for this component category.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are direct functional equivalents to the RC1608F28R7CS based on identical electrical specifications, mechanical package compatibility, and regulatory compliance status.

Direct Equivalent (Preferred for Drop-In Replacement): RC0603FR-0728R7L (YAGEO) - Maintains identical moisture-resistant thick film construction without automotive qualification. Suitable for general industrial applications. Highest inventory availability at 20,016 pieces.

Automotive-Qualified Alternatives: CRCW060328R7FKEA (Vishay Dale), ERJ-3EKF28R7V (Panasonic Electronic Components), and RMCF0603FT28R7 (Stackpole Electronics Inc) all include AEC-Q200 automotive qualification. These parts are functionally equivalent to the RC1608F28R7CS and provide additional qualification for automotive applications. Selection among these three depends on supply chain availability and procurement preferences.

All substitute parts maintain Active product status, full RoHS3 compliance, and REACH unaffected designation. No performance degradation occurs when substituting any listed part for the RC1608F28R7CS in applications within the specified operating temperature range and power dissipation limits.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0728R7L replace RC1608F28R7CS in all applications?

A: Yes. RC0603FR-0728R7L is a direct electrical and mechanical equivalent. Both parts share identical resistance (28.7 Ohms), tolerance (±1%), power rating (0.1W), package (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and compliance status (RoHS3, REACH unaffected, MSL 1). The primary difference is manufacturer source (YAGEO vs. Samsung Electro-Mechanics).

Q: What is the difference between the standard RC1608F28R7CS and the automotive-qualified substitutes?

A: The RC1608F28R7CS is specified for general industrial use with moisture-resistant thick film construction. CRCW060328R7FKEA, ERJ-3EKF28R7V, and RMCF0603FT28R7 include AEC-Q200 automotive qualification, indicating compliance with automotive reliability and testing standards. All other electrical and mechanical parameters remain identical. Automotive-qualified parts are suitable for both automotive and general industrial applications.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within supplier tolerances. RC1608F28R7CS, RC0603FR-0728R7L, and ERJ-3EKF28R7V specify 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW060328R7FKEA and RMCF0603FT28R7 specify 0.061" L x 0.033" W (1.55mm x 0.85mm) and 0.061" L x 0.031" W (1.55mm x 0.80mm) respectively, with 0.020" (0.50mm) and 0.022" (0.55mm) maximum seated heights. These variations are within standard PCB design tolerances for 0603 package footprints and do not affect substitution eligibility.

Q: Which substitute part has the best supply availability?

A: ERJ-3EKF28R7V (Panasonic Electronic Components) has the highest inventory at 143,378 pieces. RC0603FR-0728R7L (YAGEO) has 20,016 pieces available. CRCW060328R7FKEA (Vishay Dale) has 29,150 pieces. RMCF0603FT28R7 (Stackpole Electronics Inc) has 1,457 pieces. Availability should be confirmed with your supplier at time of procurement.

Q: Can I use these substitutes in high-reliability applications?

A: All listed parts maintain Active product status, RoHS3 compliance, and MSL 1 (unlimited) moisture sensitivity rating. Automotive-qualified options (CRCW060328R7FKEA, ERJ-3EKF28R7V, RMCF0603FT28R7) provide additional qualification documentation suitable for high-reliability and automotive applications. For mission-critical applications, consult manufacturer datasheets and qualification documentation.

Q: Is tape and reel packaging available for all substitutes?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging format, matching the original RC1608F28R7CS packaging specification.
