RC1608F48R7CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F48R7CS is a 48.7 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.1W (1/10W) power dissipation in a 0603 (1608 Metric) surface mount package. 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 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.

• Tolerance: ±1% (exact)
• Power rating: 0.1W / 1/10W (exact)
• Package: 0603 (1608 Metric) (exact)
• Composition: Thick Film (exact)
• Temperature coefficient: ±100ppm/°C (exact)
• Operating temperature range: -55°C to 155°C (exact)
• RoHS3 compliance (minimum requirement)
• MSL 1 rating (minimum requirement)

Substitution Categories:

Direct Equivalent: RC0603FR-0748R7L (YAGEO) — Identical electrical and mechanical specifications with identical packaging format. Moisture-resistant feature maintained. Suitable for one-to-one replacement without design modification.

Upgrade Substitute: MCR03ERTF48R7 (Rohm Semiconductor) — Meets all mandatory electrical parameters. Note: Product status is Discontinued at DiGi Electronics; availability may be limited. Packaging format is Cut Tape (CT) & Digi-Reel® rather than standard Tape & Reel.

Similar Substitutes with Enhanced Certification: CRCW060348R7FKEA (Vishay Dale), ERJ-3EKF48R7V (Panasonic Electronic Components), RMCF0603FT48R7 (Stackpole Electronics Inc) — All meet mandatory electrical and mechanical parameters with addition of Automotive AEC-Q200 certification. Physical dimensions show minor variations within acceptable tolerance for 0603 package class. These parts are suitable for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RC0603FR-0748R7L (YAGEO) is the primary direct equivalent. This part maintains identical electrical specifications, moisture-resistant construction, and standard Tape & Reel packaging. Product status is Active with established supply availability (265,648 pcs in stock). Selection of this part requires no design modification and provides direct functional equivalence.

For Automotive and High-Reliability Applications: CRCW060348R7FKEA (Vishay Dale), ERJ-3EKF48R7V (Panasonic Electronic Components), or RMCF0603FT48R7 (Stackpole Electronics Inc) are appropriate selections when AEC-Q200 automotive qualification is required. All three parts meet the mandatory electrical and mechanical parameters while providing enhanced reliability certification. All three maintain Active product status. Selection among these three parts depends on supply chain availability and procurement preferences.

Regarding MCR03ERTF48R7 (Rohm Semiconductor): This part meets all mandatory electrical and mechanical specifications but carries Discontinued at DiGi Electronics status. While 1,828 pcs are currently in stock, future availability is not assured. This part should be considered only when supply of active alternatives is constrained and existing inventory can be secured.

Packaging Consideration: MCR03ERTF48R7 is supplied in Cut Tape (CT) & Digi-Reel® format rather than standard Tape & Reel. This may require adjustment to automated assembly equipment programming and should be evaluated against production line capabilities.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0748R7L be used as a direct replacement for RC1608F48R7CS without any circuit design changes?

A: Yes. RC0603FR-0748R7L is a direct equivalent meeting all electrical specifications (48.7 Ohms ±1%, 0.1W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range), mechanical specifications (0603 package, 2 terminations), and compliance requirements (RoHS3, MSL 1). No design modification is required.

Q: What is the difference between the substitute parts in terms of application suitability?

A: RC0603FR-0748R7L and MCR03ERTF48R7 are general-purpose industrial equivalents. CRCW060348R7FKEA, ERJ-3EKF48R7V, and RMCF0603FT48R7 include Automotive AEC-Q200 certification, making them suitable for automotive and high-reliability applications where enhanced qualification is specified. All parts are electrically and mechanically identical.

Q: Why do some substitute parts have slightly different physical dimensions listed?

A: Minor dimensional variations within the 0603 package class (such as length 0.061" to 0.063" and height 0.020" to 0.022") are within acceptable tolerance for this component category and do not affect PCB footprint compatibility or assembly process. All parts are specified for the same 0603 (1608 Metric) package designation.

Q: Is MCR03ERTF48R7 still available for new designs?

A: MCR03ERTF48R7 carries Discontinued at DiGi Electronics status. While current inventory exists (1,828 pcs), this part should not be selected for new designs requiring long-term supply assurance. Active alternatives such as RC0603FR-0748R7L or the AEC-Q200 qualified parts are recommended for new designs.

Q: What does the packaging format difference (Tape & Reel vs. Cut Tape & Digi-Reel) mean for production?

A: Tape & Reel (TR) is the standard format for automated pick-and-place assembly equipment. Cut Tape (CT) & Digi-Reel® format used by MCR03ERTF48R7 requires different feeder setup and may require equipment reconfiguration. Verify compatibility with your assembly equipment before selecting this part.

Q: Are all substitute parts RoHS3 compliant and MSL 1 rated?

A: Yes. All listed substitute parts meet RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the RC1608F48R7CS.

Q: Which substitute part should I select if I need the highest inventory availability?

A: RC0603FR-0748R7L (YAGEO) offers the highest inventory availability with 265,648 pcs in stock, compared to 1,828 pcs for MCR03ERTF48R7, 20,076 pcs for CRCW060348R7FKEA, 57,715 pcs for ERJ-3EKF48R7V, and 1,086 pcs for RMCF0603FT48R7.
