Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F622CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 6.2 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package / Case: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant
• Number of terminations: 2

Substitute parts are categorized into three groups based on additional features and certifications:

Direct Substitutes: Parts meeting all mandatory parameters with identical feature sets and standard industrial packaging.

Upgrade Substitutes: Parts meeting all mandatory parameters with enhanced features such as automotive AEC-Q200 qualification and high voltage capability.

Similar Substitutes: Parts meeting all mandatory parameters with automotive AEC-Q200 qualification or alternative packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Standard Industrial Applications):

CR0603-FX-6201ELF (Bourns Inc.) and RC0603FR-076K2L (YAGEO) are direct functional equivalents to the RC1608F622CS. Both parts maintain identical electrical specifications, temperature characteristics, and moisture resistance properties. The primary distinction is packaging format: CR0603-FX-6201ELF is supplied in Cut Tape and Digi-Reel format, while RC0603FR-076K2L is also available in Cut Tape and Digi-Reel format. Both parts are ROHS3 compliant and suitable for standard industrial applications where automotive qualification is not required.

Upgrade Substitute (Automotive and High Reliability Applications):

KTR03EZPF6201 (Rohm Semiconductor) meets all mandatory electrical and thermal parameters while providing automotive AEC-Q200 qualification and high voltage capability. This part is supplied in Tape & Reel format and is appropriate for applications requiring enhanced reliability standards and automotive-grade components.

Similar Substitutes (Automotive Applications):

AC0603FR-076K2L (YAGEO), CRCW06036K20FKEA (Vishay Dale), ERJ-3EKF6201V (Panasonic Electronic Components), and RMCF0603FT6K20 (Stackpole Electronics Inc) all meet mandatory electrical specifications and carry automotive AEC-Q200 qualification. These parts are suitable for automotive and high-reliability applications. Packaging options include both Tape & Reel and Cut Tape formats. Minor dimensional variations exist within the 0603 package specification; CRCW06036K20FKEA and RMCF0603FT6K20 exhibit slight length and height differences within acceptable tolerances.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F622CS with any of the listed equivalent parts?

A: Substitution is permissible only when all mandatory electrical and thermal parameters match exactly. All listed parts meet the core requirements of 6.2 kOhms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Selection depends on application requirements and packaging preferences.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (CR0603-FX-6201ELF and RC0603FR-076K2L) provide identical functionality for standard industrial applications. Upgrade substitutes (KTR03EZPF6201) add automotive AEC-Q200 qualification and high voltage capability, making them suitable for automotive and high-reliability applications. All parts maintain identical core electrical specifications.

Q: Does packaging format affect electrical performance?

A: Packaging format (Tape & Reel versus Cut Tape and Digi-Reel) does not affect electrical performance. The choice between packaging formats is determined by manufacturing and assembly process requirements. Tape & Reel format is suitable for automated pick-and-place assembly, while Cut Tape and Digi-Reel formats provide flexibility for lower-volume or mixed-component applications.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to the 0603 (1608 Metric) package specification. Minor dimensional variations exist within standard tolerances. CRCW06036K20FKEA measures 0.061" L x 0.033" W with 0.020" maximum seated height, while most other parts measure 0.063" L x 0.031" W with 0.022" maximum seated height. These variations remain within 0603 package specifications and do not affect PCB layout or assembly compatibility.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select from parts carrying AEC-Q200 qualification: KTR03EZPF6201 (Rohm Semiconductor), AC0603FR-076K2L (YAGEO), CRCW06036K20FKEA (Vishay Dale), ERJ-3EKF6201V (Panasonic Electronic Components), or RMCF0603FT6K20 (Stackpole Electronics Inc). All five parts meet automotive reliability standards while maintaining identical electrical specifications to the RC1608F622CS.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. All listed parts, including the RC1608F622CS, carry MSL 1 rating, meaning they do not require special moisture-controlled storage or baking procedures prior to assembly. This simplifies inventory management and reduces handling requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant, matching the RC1608F622CS compliance status. This ensures compatibility with environmental regulations and customer requirements for lead-free and restricted substance compliance.
