RC1608F9760CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F9760CS is a 976 Ohms ±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 stable resistance values across the -55°C to 155°C operating temperature range. Equivalent and substitute parts are identified to support supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when specific application requirements necessitate alternative manufacturer specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F9760CS are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical or equivalent specifications across all critical parameters: resistance value (976 Ohms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3). These parts are functionally interchangeable without circuit redesign or performance degradation.

Similar Substitutes share all core electrical specifications and package format but include enhanced features such as automotive AEC-Q200 qualification. These parts exceed the baseline requirements of the original component and are suitable for applications requiring higher reliability standards or automotive-grade specifications.

The substitution logic is based strictly on the following allowed parameters:

• Electrical equivalence: Resistance, tolerance, power rating, temperature coefficient
• Physical compatibility: Package type, case dimensions, termination count
• Environmental performance: Operating temperature range, moisture sensitivity
• Regulatory alignment: RoHS and REACH compliance status

Engineering Selection Recommendations

Direct Substitution (Preferred for Standard Applications)

CR0603-FX-9760ELF (Bourns Inc.) and RC0603FR-07976RL (YAGEO) are direct functional equivalents to the RC1608F9760CS. Both parts maintain identical electrical specifications, package format, and regulatory compliance. Selection between these options is based on procurement availability and supply chain logistics. RC0603FR-07976RL demonstrates significantly higher inventory availability (140,904 units) compared to CR0603-FX-9760ELF (25,769 units), making it the preferred choice for high-volume production requirements.

Enhanced Specification Substitution (Automotive and High-Reliability Applications)

CRCW0603976RFKEA (Vishay Dale), ERJ-3EKF9760V (Panasonic Electronic Components), and RMCF0603FT976R (Stackpole Electronics Inc) are qualified to automotive AEC-Q200 standard. These parts exceed the baseline specifications of the RC1608F9760CS while maintaining full electrical and mechanical compatibility. Selection of AEC-Q200 qualified parts is appropriate for applications requiring automotive-grade reliability, extended temperature cycling validation, or enhanced failure rate documentation. All three AEC-Q200 options maintain ROHS3 compliance and identical operating temperature ranges.

Packaging Consideration

CRCW0603976RFKEA is supplied in Cut Tape and Digi-Reel packaging, differing from the standard Tape & Reel format of other substitutes. This packaging option is suitable for lower-volume applications or manual assembly processes where standard reel quantities are excessive.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-9760ELF be used as a direct replacement for RC1608F9760CS without circuit modification?

A: Yes. CR0603-FX-9760ELF is a direct substitute with identical resistance value (976 Ohms), tolerance (±1%), power rating (0.1W), package format (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No circuit redesign is required.

Q: What is the difference between the standard RC1608F9760CS and the AEC-Q200 qualified alternatives?

A: The RC1608F9760CS is a general-purpose thick film resistor. AEC-Q200 qualified alternatives (CRCW0603976RFKEA, ERJ-3EKF9760V, RMCF0603FT976R) meet automotive industry reliability standards including extended temperature cycling, moisture resistance validation, and failure rate documentation. All maintain identical electrical specifications and package format. AEC-Q200 qualification is not required for non-automotive applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the RC1608F9760CS.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-07976RL (YAGEO) has the highest inventory availability at 140,904 units, followed by ERJ-3EKF9760V (Panasonic) at 58,591 units and CRCW0603976RFKEA (Vishay Dale) at 38,505 units.

Q: Can AEC-Q200 qualified parts be used in non-automotive applications?

A: Yes. AEC-Q200 qualified parts exceed baseline specifications and are fully compatible with non-automotive applications. Their use introduces no performance degradation or incompatibility. Selection is based on application requirements and cost considerations.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts, including the RC1608F9760CS and all substitutes, carry MSL 1 rating, eliminating moisture sensitivity constraints during storage and handling.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations are minimal and within standard PCB design tolerances. CRCW0603976RFKEA and RMCF0603FT976R have slightly reduced length (1.55mm vs. 1.60mm) and height (0.50mm vs. 0.55mm) compared to RC1608F9760CS, but these differences do not affect PCB layout compatibility for standard 0603 footprints.

Q: What packaging format should be selected for high-volume production?

A: Tape & Reel packaging is standard for high-volume automated assembly. RC0603FR-07976RL, CR0603-FX-9760ELF, ERJ-3EKF9760V, and RMCF0603FT976R are supplied in Tape & Reel format. CRCW0603976RFKEA offers Cut Tape and Digi-Reel options suitable for lower-volume or manual assembly processes.
