Parameter Comparison

Engineering Selection Recommendations

For General Industrial and Consumer Applications:

The RC0603FR-0756K2L (YAGEO) and CR0603-FX-5622ELF (Bourns Inc.) are direct functional equivalents to the RC1608F5622CS. Both parts maintain identical electrical specifications, mechanical dimensions, and ROHS3 compliance. Selection between these options depends on packaging format availability and supply chain requirements. The RC0603FR-0756K2L offers flexibility with Cut Tape and Digi-Reel® packaging options, while CR0603-FX-5622ELF is supplied in Tape & Reel format.

For Automotive Applications (AEC-Q200 Required):

When automotive qualification is required, the following parts are suitable substitutes:

• AC0603FR-0756K2L (YAGEO) - Standard automotive grade
• AF0603FR-0756K2L (YAGEO) - Automotive grade with anti-sulfur construction
• CRCW060356K2FKEA (Vishay Dale) - Automotive grade, ROHS3 compliant
• ERJ-3EKF5622V (Panasonic Electronic Components) - Automotive grade
• RMCF0603FG56K2 (Stackpole Electronics Inc) - Automotive grade
• RMCF0603FT56K2 (Stackpole Electronics Inc) - Automotive grade with highest inventory availability

All automotive-qualified substitutes maintain the same electrical performance and operating temperature range as the main part.

Compliance Considerations:

CRCW060356K2FKTA (Vishay Dale) is not ROHS3 compliant and is REACH affected. This part is not recommended for new designs requiring ROHS3 compliance.

All other substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance profile of the RC1608F5622CS.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F5622CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the mandatory electrical parameters (56.2 kOhms, ±1% tolerance, 0.1W power rating, ±100ppm/°C temperature coefficient, -55°C to +155°C operating range) and mechanical specifications (0603 package, 2 terminations, thick film composition). Direct board-level replacement is possible without circuit modification.

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

A: Automotive-qualified parts (AC0603FR-0756K2L, AF0603FR-0756K2L, CRCW060356K2FKEA, ERJ-3EKF5622V, RMCF0603FG56K2, RMCF0603FT56K2) carry AEC-Q200 certification, indicating compliance with automotive industry reliability and quality standards. These parts are suitable for automotive applications where qualification is mandatory. The RC1608F5622CS and non-automotive substitutes (CR0603-FX-5622ELF, RC0603FR-0756K2L) are not automotive-qualified and should not be used in applications requiring AEC-Q200 certification.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Tape & Reel, or Digi-Reel®) affects only handling, storage, and assembly processes. Electrical and mechanical performance is identical across all packaging formats for the same part number. Selection should be based on manufacturing equipment compatibility and supply chain logistics.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 0603 package specification. The RC1608F5622CS, CR0603-FX-5622ELF, RC0603FR-0756K2L, AC0603FR-0756K2L, AF0603FR-0756K2L, ERJ-3EKF5622V, RMCF0603FG56K2, and RMCF0603FT56K2 all measure 0.063" L × 0.031" W (1.60mm × 0.80mm) with maximum seated height of 0.022" (0.55mm). The CRCW060356K2FKEA and CRCW060356K2FKTA measure 0.061" L × 0.033" W (1.55mm × 0.85mm) with maximum seated height of 0.020" (0.50mm). These variations remain within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: What is the difference between AF0603FR-0756K2L and AC0603FR-0756K2L?

A: Both parts are YAGEO automotive-qualified resistors with identical electrical specifications. AF0603FR-0756K2L includes anti-sulfur construction as an additional feature, providing enhanced protection in sulfur-rich environments. AC0603FR-0756K2L is the standard automotive version without anti-sulfur treatment. Selection depends on application environment requirements.

Q: Why is CRCW060356K2FKTA not recommended?

A: CRCW060356K2FKTA is not ROHS3 compliant and is REACH affected, whereas the RC1608F5622CS is ROHS3 compliant and REACH unaffected. For new designs and applications requiring regulatory compliance with ROHS3 standards, CRCW060356K2FKTA is not suitable. Use CRCW060356K2FKEA instead, which maintains ROHS3 compliance.

Q: Which substitute has the highest inventory availability?

A: RMCF0603FT56K2 (Stackpole Electronics Inc) has the highest inventory with 124,921 pieces in stock, followed by CRCW060356K2FKTA with 25,053 pieces and CRCW060356K2FKEA with 30,100 pieces. For applications requiring immediate availability, RMCF0603FT56K2 is the preferred choice among automotive-qualified options.

Q: Can I use these substitutes interchangeably in the same assembly?

A: Yes, all listed substitute parts are electrically and mechanically interchangeable with the RC1608F5622CS. However, if your application requires automotive qualification, you must use only AEC-Q200 qualified parts (AC0603FR-0756K2L, AF0603FR-0756K2L, CRCW060356K2FKEA, ERJ-3EKF5622V, RMCF0603FG56K2, or RMCF0603FT56K2). Mixing qualified and non-qualified parts in the same assembly may violate automotive compliance requirements.
