Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F1433CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 143 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 compliance

All substitute parts listed meet these mandatory parameters. Substitute parts are grouped into three categories based on product status and feature set:

Direct Substitutes (Functionally Identical): CR0603-FX-1433ELF (Bourns Inc.) and RC0603FR-07143KL (YAGEO) provide direct functional equivalence with identical electrical and mechanical specifications.

Upgrade Substitutes (Enhanced Certifications): AC0603FR-07143KL, CRCW0603143KFKEA, ERJ-3EKF1433V, and RMCF0603FT143K include automotive AEC-Q200 qualification in addition to base specifications, suitable for applications requiring automotive-grade reliability.

Discontinued Status: MCR03ERTF1433 (Rohm Semiconductor) is discontinued at DiGi Electronics but remains functionally equivalent; use only when supply from active manufacturers is unavailable.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR0603-FX-1433ELF (Bourns Inc.) or RC0603FR-07143KL (YAGEO) are recommended as direct substitutes. Both maintain identical electrical and mechanical specifications with active product status and established supply availability. RC0603FR-07143KL offers the highest inventory level (299,920 units), ensuring supply continuity.

For Automotive Applications: AC0603FR-07143KL, CRCW0603143KFKEA, ERJ-3EKF1433V, or RMCF0603FT143K are required when AEC-Q200 automotive qualification is mandated by design specifications. RMCF0603FT143K (Stackpole Electronics Inc) provides the largest inventory (395,992 units) among automotive-qualified options.

For Legacy System Maintenance: MCR03ERTF1433 (Rohm Semiconductor) remains functionally equivalent but is discontinued at DiGi Electronics. This part should be used only when existing inventory is available or when design documentation specifically requires Rohm components.

Compliance Verification: All listed substitutes maintain RoHS3 compliance, REACH unaffected status, and identical moisture sensitivity level (MSL 1). No additional qualification testing is required when substituting between parts within the same application category (industrial or automotive).

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07143KL replace RC1608F1433CS in any application?

A: Yes. RC0603FR-07143KL (YAGEO) meets all mandatory electrical and mechanical parameters: 143 kOhms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and RoHS3 compliance. Direct substitution is valid without design modification.

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

A: Automotive-qualified parts (AC0603FR-07143KL, CRCW0603143KFKEA, ERJ-3EKF1433V, RMCF0603FT143K) carry AEC-Q200 certification, indicating compliance with automotive reliability and testing standards. Standard parts (CR0603-FX-1433ELF, RC0603FR-07143KL) do not carry this certification. Use automotive-qualified parts only when design specifications explicitly require AEC-Q200 compliance.

Q: Are there physical dimension differences between substitutes?

A: Minor dimensional variations exist. Most substitutes maintain 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW0603143KFKEA and RMCF0603FT143K have slightly different dimensions (1.55mm x 0.85mm and 1.55mm x 0.80mm respectively) but remain within 0603 package tolerance and are mechanically compatible with standard PCB footprints.

Q: Is MCR03ERTF1433 still available for new designs?

A: MCR03ERTF1433 is discontinued at DiGi Electronics and should not be specified for new designs. Use active alternatives: CR0603-FX-1433ELF, RC0603FR-07143KL, or automotive-qualified options instead.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All listed substitutes maintain MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. No special precautions are required when substituting between parts.

Q: Which substitute offers the best supply availability?

A: RMCF0603FT143K (Stackpole Electronics Inc) provides the highest inventory level at 395,992 units. RC0603FR-07143KL (YAGEO) is the second option with 299,920 units. Both ensure consistent supply for high-volume production.
