Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F1652CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 16.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package / Case: 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)
• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

Acceptable Variation Parameters:

• Manufacturer identity (different manufacturers permitted)
• Packaging format (Tape & Reel or Cut Tape acceptable)
• Minor dimensional tolerances within 0603 specification
• Additional certifications (AEC-Q200 automotive qualification is additive, not restrictive)

All substitute parts listed below meet these mandatory criteria and are therefore electrically and mechanically interchangeable with the RC1608F1652CS in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

CR0603-FX-1652ELF (Bourns Inc.) and RC0603FR-0716K5L (YAGEO) are direct substitutes with identical electrical and mechanical specifications to the RC1608F1652CS. Both parts are Active status with substantial inventory availability (54034 and 79803 units respectively). These parts are suitable for direct replacement in applications where moisture resistance is the primary environmental requirement and automotive qualification is not mandated.

Automotive-Qualified Alternatives:

AC0603FR-0716K5L (YAGEO), CRCW060316K5FKEA (Vishay Dale), ERJ-3EKF1652V (Panasonic Electronic Components), and RMCF0603FT16K5 (Stackpole Electronics Inc) are all AEC-Q200 automotive-qualified equivalents. These parts maintain identical core electrical specifications while adding automotive-grade reliability certification. Selection among these four options should be based on inventory availability and existing supply chain relationships. CRCW060316K5FKEA offers the highest inventory level (32778 units), while ERJ-3EKF1652V provides the largest stock position (71618 units).

Discontinued Part Consideration:

MCR03ERTF1652 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics and should not be selected for new designs or long-term production applications despite current inventory availability (1097 units). This part is suitable only for legacy system maintenance or repair applications where supply continuity cannot be guaranteed.

Selection Criteria Summary:

• For standard industrial applications: CR0603-FX-1652ELF or RC0603FR-0716K5L
• For automotive applications: AC0603FR-0716K5L, CRCW060316K5FKEA, ERJ-3EKF1652V, or RMCF0603FT16K5
• For maximum inventory availability: ERJ-3EKF1652V (71618 units)
• For cost optimization: Evaluate current pricing across CR0603-FX-1652ELF, RC0603FR-0716K5L, and CRCW060316K5FKEA

Frequently Asked Questions (FAQ)

Q: Can I use an automotive AEC-Q200 qualified resistor in a non-automotive application?

A: Yes. AEC-Q200 qualification represents an additional quality and reliability standard that exceeds standard industrial requirements. Parts such as AC0603FR-0716K5L, CRCW060316K5FKEA, ERJ-3EKF1652V, and RMCF0603FT16K5 are fully compatible with non-automotive applications and provide enhanced reliability margins.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape packaging is supplied in shorter tape segments for manual handling or lower-volume applications. MCR03ERTF1652 is supplied in Cut Tape & Digi-Reel format. Both packaging formats contain electrically and mechanically identical components; selection depends on assembly process requirements.

Q: Are all listed substitute parts truly interchangeable with RC1608F1652CS?

A: Yes, all parts listed in the Parameter Comparison table meet the mandatory matching criteria for electrical and mechanical interchangeability. All parts share identical resistance value (16.5 kOhms), 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 RoHS3 compliance. Dimensional variations within the 0603 specification are acceptable and do not affect circuit performance or PCB layout.

Q: Why should I avoid MCR03ERTF1652 despite available inventory?

A: MCR03ERTF1652 is marked as Discontinued at DiGi Electronics, indicating that the manufacturer has ceased production or the distributor has removed it from active catalog status. Using discontinued parts in new designs creates supply chain risk and may result in unavailability for future production runs, rework, or field replacements. This part should be reserved only for maintenance of existing systems where no alternative is available.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and requires no special moisture control during storage or handling. This is the least restrictive MSL rating and means the part can be stored at standard ambient conditions without desiccant packaging or controlled humidity environments. All listed substitute parts carry MSL 1 rating.

Q: How do I select between multiple substitute options?

A: Primary selection criteria are: (1) Product Status (Active preferred over Discontinued), (2) Inventory availability for your required volume, (3) Application requirements (automotive vs. industrial), (4) Existing supply chain relationships with the manufacturer, and (5) Current pricing. All Active parts listed are technically equivalent and suitable for direct substitution.
