Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F2800CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 280 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Specifications:

• Package type: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Compliance & Regulatory:

• RoHS3 Compliant status (exact match required)
• REACH Unaffected status (exact match required)

All substitute parts listed below meet these criteria. Additional features such as Automotive AEC-Q200 qualification represent enhancements that do not preclude substitution but indicate expanded application scope.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Highest Compatibility):

CR0603-FX-2800ELF (Bourns Inc.) and RC0603FR-07280RL (YAGEO) are direct functional equivalents to the RC1608F2800CS. Both maintain Active product status, identical electrical and mechanical specifications, and standard industrial packaging. These parts are suitable for direct substitution without design modification.

Active Alternatives with Enhanced Qualification:

AC0603FR-07280RL (YAGEO), CRCW0603280RFKEA (Vishay Dale), ERJ-3EKF2800V (Panasonic Electronic Components), and RMCF0603FT280R (Stackpole Electronics Inc) are all Active products that meet all electrical and mechanical requirements. These parts carry Automotive AEC-Q200 qualification, which represents an additional quality and reliability standard. This qualification does not restrict their use in non-automotive applications and indicates enhanced manufacturing process control.

Discontinued Alternative:

MCR03ERTF2800 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics. While it maintains full electrical and mechanical equivalence, its discontinued status indicates limited future availability. This part should be considered only when other alternatives are unavailable and existing inventory is confirmed.

Dimensional Considerations:

CRCW0603280RFKEA and RMCF0603FT280R exhibit minor dimensional variations within the 0603 package specification. CRCW0603280RFKEA measures 1.55mm x 0.85mm with 0.50mm maximum height, while RMCF0603FT280R measures 1.55mm x 0.80mm with 0.55mm maximum height. These variations remain within standard 0603 package tolerances and do not affect PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-2800ELF replace RC1608F2800CS without any design changes?

A: Yes. CR0603-FX-2800ELF is a direct equivalent. All electrical specifications (280 Ohms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C), mechanical dimensions (0603 package, 1.60mm x 0.80mm, 0.55mm height), and compliance certifications (ROHS3, MSL 1) are identical. PCB footprints and assembly processes require no modification.

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

A: AEC-Q200 qualification indicates the part meets automotive industry reliability standards including enhanced testing, process control, and traceability requirements. Parts such as AC0603FR-07280RL, CRCW0603280RFKEA, ERJ-3EKF2800V, and RMCF0603FT280R carry this qualification. For non-automotive applications, AEC-Q200 qualification provides additional assurance of manufacturing quality but does not alter electrical or mechanical performance.

Q: Are there packaging differences between substitute parts?

A: Most substitute parts are supplied in Tape & Reel (TR) format, matching the RC1608F2800CS packaging. MCR03ERTF2800 is supplied in Cut Tape (CT) & Digi-Reel format. Tape & Reel packaging is standard for automated assembly processes. Cut Tape format is suitable for manual assembly or lower-volume applications. Verify packaging compatibility with your assembly process before selection.

Q: Why is MCR03ERTF2800 listed if it is discontinued?

A: MCR03ERTF2800 is included because it maintains full electrical and mechanical equivalence to RC1608F2800CS. Its discontinued status at DiGi Electronics indicates reduced future availability. This part should be selected only when inventory is confirmed available and other alternatives are unsuitable. For new designs, select from Active status alternatives.

Q: Do dimensional variations in CRCW0603280RFKEA and RMCF0603FT280R affect PCB compatibility?

A: No. Both parts measure within standard 0603 package tolerances. CRCW0603280RFKEA (1.55mm x 0.85mm x 0.50mm max height) and RMCF0603FT280R (1.55mm x 0.80mm x 0.55mm max height) fit standard 0603 PCB footprints. Minor dimensional variations do not affect placement, soldering, or electrical performance.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, all listed substitute parts are mechanically and electrically interchangeable with RC1608F2800CS. They share identical 0603 package footprints, electrical specifications, and compliance certifications. Assembly equipment, solder profiles, and handling procedures require no modification.

Q: Which substitute part offers the best long-term availability?

A: RC0603FR-07280RL (YAGEO) and ERJ-3EKF2800V (Panasonic Electronic Components) show the highest inventory levels (42,977 and 79,986 pieces respectively) and Active product status, indicating strong market presence and sustained manufacturing. These parts are recommended for designs requiring long-term supply security.
