Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F621CS are classified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Resistance value: 620 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Parameters:

• Package type: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• REACH Unaffected status (required)

All substitute parts listed meet these criteria. Additional features such as Automotive AEC-Q200 certification represent enhanced specifications beyond the base requirements and do not prevent substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement of the RC1608F621CS. Selection among equivalent parts should be based on the following criteria:

For General-Purpose Applications: CR0603-FX-6200ELF (Bourns Inc.) and RC0603FR-07620RL (YAGEO) are direct functional equivalents with identical specifications to the main part. Both maintain the standard moisture-resistant thick film composition without automotive certification.

For Automotive Applications: AC0603FR-07620RL (YAGEO), CRCW0603620RFKEA (Vishay Dale), ERJ-3EKF6200V (Panasonic Electronic Components), and RMCF0603FT620R (Stackpole Electronics Inc) include AEC-Q200 automotive qualification. These parts are suitable for automotive-grade circuit designs while maintaining full compatibility with standard applications.

Packaging Considerations: RC1608F621CS and CR0603-FX-6200ELF are supplied in Tape & Reel (TR) packaging. RC0603FR-07620RL is available in Cut Tape (CT) & Digi-Reel® format. All automotive-qualified alternatives are supplied in Tape & Reel (TR) packaging. Packaging format selection depends on assembly process requirements and volume specifications.

Inventory Availability: RC0603FR-07620RL (YAGEO) offers the highest inventory availability at 219,896 pieces. RMCF0603FT620R (Stackpole Electronics Inc) provides 60,692 pieces. CRCW0603620RFKEA (Vishay Dale) stocks 55,850 pieces. All parts maintain active product status with continuous supply.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F621CS with any of the listed parts in my circuit design?

A: Yes. All listed parts meet identical electrical specifications (620Ω ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical requirements (0603 package, thick film composition, 2 terminations). Direct substitution is functionally equivalent.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates automotive-grade qualification with enhanced reliability testing and traceability requirements. Parts with AEC-Q200 (AC0603FR-07620RL, CRCW0603620RFKEA, ERJ-3EKF6200V, RMCF0603FT620R) are suitable for automotive applications. Parts without AEC-Q200 (RC1608F621CS, CR0603-FX-6200ELF, RC0603FR-07620RL) are suitable for general-purpose and industrial applications. AEC-Q200 parts can be used in non-automotive applications without restriction.

Q: Are there dimensional differences between substitute parts?

A: Dimensional variations exist within tolerance. RC1608F621CS, CR0603-FX-6200ELF, and ERJ-3EKF6200V specify 0.063" L x 0.031" W (1.60mm x 0.80mm). CRCW0603620RFKEA and RMCF0603FT620R specify 0.061" L x 0.033" W (1.55mm x 0.85mm) and 0.061" L x 0.031" W (1.55mm x 0.80mm) respectively. All parts conform to 0603 (1608 Metric) package classification and are mechanically interchangeable on standard PCB layouts.

Q: What packaging options are available?

A: RC1608F621CS and CR0603-FX-6200ELF are supplied in Tape & Reel (TR). RC0603FR-07620RL is available in Cut Tape (CT) & Digi-Reel®. All automotive-qualified alternatives (AC0603FR-07620RL, CRCW0603620RFKEA, ERJ-3EKF6200V, RMCF0603FT620R) are supplied in Tape & Reel (TR). Packaging selection depends on assembly equipment compatibility and order volume requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed, including the main part RC1608F621CS, have Moisture Sensitivity Level 1 (Unlimited). This indicates no moisture-related handling restrictions during storage, transport, or assembly.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are RoHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
