Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F6042CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 60.4 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
• Termination count: 2

Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant or equivalent
• REACH Status: REACH Unaffected or REACH Affected (application-dependent)

Substitute parts are categorized as Direct, Upgrade, or Similar based on feature parity and additional certifications. Direct substitutes maintain identical specifications. Upgrade substitutes add automotive AEC-Q200 qualification or high-voltage features. Similar substitutes include automotive-qualified variants with minor dimensional tolerances within acceptable assembly parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Functionally Identical):

CR0603-FX-6042ELF (Bourns Inc.) is a direct functional equivalent to RC1608F6042CS. Both parts share identical electrical specifications, package dimensions, and ROHS3 compliance status. This substitute is suitable for applications where moisture-resistant thick film construction is the primary requirement and automotive qualification is not mandated.

Upgrade Substitutes (Enhanced Specifications):

KTR03EZPF6042 (Rohm Semiconductor) qualifies as an upgrade substitute with automotive AEC-Q200 certification and high-voltage features. This part maintains all electrical and thermal parameters of the primary part while adding automotive-grade reliability qualification. Selection of this part is appropriate when designs require automotive-qualified components or when high-voltage stress conditions are present.

Similar Substitutes (Automotive-Qualified Variants):

AC0603FR-0760K4L (YAGEO), CRCW060360K4FKEA (Vishay Dale), ERJ-3EKF6042V (Panasonic), RMCF0603FG60K4 (Stackpole), and RMCF0603FT60K4 (Stackpole) are automotive AEC-Q200 qualified alternatives. These parts maintain electrical equivalence while providing automotive-grade reliability certification. Selection depends on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and supply chain availability.

Compliance Consideration:

CRCW060360K4FKTA (Vishay Dale) is RoHS non-compliant and REACH affected. This part is suitable only for applications where RoHS exemptions apply or where legacy component specifications are required. Use of this part in new designs targeting ROHS3 compliance is not recommended.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F6042CS with CR0603-FX-6042ELF in my design?

A: Yes. CR0603-FX-6042ELF is a direct substitute meeting all electrical, thermal, and mechanical specifications of RC1608F6042CS. Both parts are 60.4 kOhms ±1%, 0.1W, 0603 package, with ±100ppm/°C temperature coefficient and -55°C to 155°C operating range. ROHS3 compliance status is identical. Substitution is valid without design modification.

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

A: Automotive AEC-Q200 qualification indicates the part has undergone additional reliability testing and qualification per automotive industry standards. Parts such as KTR03EZPF6042, AC0603FR-0760K4L, ERJ-3EKF6042V, RMCF0603FG60K4, and RMCF0603FT60K4 carry this certification. Standard parts like RC1608F6042CS and CR0603-FX-6042ELF do not carry automotive qualification. Selection of AEC-Q200 parts is required for automotive applications; standard parts are suitable for industrial and consumer applications.

Q: Does packaging type (Tape & Reel versus Cut Tape & Digi-Reel) affect electrical performance?

A: No. Packaging type affects only handling, storage, and assembly logistics. Electrical and thermal performance is identical regardless of packaging format. RC0603FR-0760K4L (Cut Tape & Digi-Reel) and RC1608F6042CS (Tape & Reel) are electrically equivalent. Selection between packaging types depends on manufacturing equipment compatibility and supply chain requirements.

Q: Why is CRCW060360K4FKTA listed as RoHS non-compliant?

A: CRCW060360K4FKTA carries RoHS non-compliant status and REACH affected designation. This part is suitable only for applications where RoHS exemptions are applicable or where legacy specifications require non-compliant components. For new designs targeting ROHS3 compliance, use CRCW060360K4FKEA (ROHS3 compliant variant) or other ROHS3 qualified alternatives.

Q: Can I use RMCF0603FT60K4 in place of RC1608F6042CS?

A: Yes. RMCF0603FT60K4 (Stackpole Electronics Inc) is a suitable substitute with automotive AEC-Q200 qualification. All electrical parameters match: 60.4 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. The automotive qualification is an additional feature that does not prevent use in standard applications.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. Both RC1608F6042CS and all listed substitutes carry MSL 1 rating, meaning no special moisture control or baking procedures are required prior to assembly. This specification is identical across all substitute parts listed.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within acceptable tolerances. RC1608F6042CS specifies 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" maximum seated height. RMCF0603FG60K4 specifies 0.061" L x 0.031" W (1.55mm x 0.80mm) with identical height. CRCW060360K4FKEA specifies 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" maximum height. These variations remain within standard 0603 package tolerances and do not affect PCB assembly compatibility.
