Engineering Selection Recommendations

Primary Equivalent (Direct Substitution): CR0603-FX-2152ELF (Bourns Inc.) and RC0603FR-0721K5L (YAGEO) are direct electrical and mechanical equivalents to RC1608F2152CS. Both maintain Active product status, ROHS3 compliance, and identical electrical specifications. Selection between these options depends on packaging format requirements: CR0603-FX-2152ELF is available in Tape & Reel format with 77,247 pieces in inventory, while RC0603FR-0721K5L is available in Tape & Reel format with 1,695,486 pieces in inventory.

Secondary Equivalents (Functionally Identical): CRCW060321K5FKEA (Vishay Dale), ERJ-3EKF2152V (Panasonic Electronic Components), and RMCF0603FT21K5 (Stackpole Electronics Inc) are functionally equivalent with identical electrical parameters and Active product status. These parts include AEC-Q200 automotive qualification, which represents an additional feature not present in the primary part but does not preclude substitution in non-automotive applications.

Discontinued Part (Limited Availability): MCR03ERTF2152 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics. While electrically and mechanically equivalent, this part should be selected only when existing inventory is confirmed available and long-term supply is not required.

Inventory Availability Consideration: RC0603FR-0721K5L (YAGEO) offers the highest inventory availability at 1,695,486 pieces, followed by CRCW060321K5FKEA (Vishay Dale) at 64,207 pieces. The primary part RC1608F2152CS maintains 814 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F2152CS with CR0603-FX-2152ELF in my circuit design?

A: Yes. CR0603-FX-2152ELF is electrically and mechanically equivalent. Both parts share identical resistance value (21.5 kOhms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance status (ROHS3, MSL 1). The only difference is packaging format: CR0603-FX-2152ELF is supplied in Tape & Reel format while RC1608F2152CS is supplied in Cut Tape format.

Q: What is the difference between the automotive-qualified parts (AC0603FR-0721K5L, CRCW060321K5FKEA, ERJ-3EKF2152V, RMCF0603FT21K5) and the non-automotive parts?

A: The automotive-qualified parts carry AEC-Q200 certification, which indicates compliance with automotive industry reliability and quality standards. However, all parts listed—both automotive-qualified and non-automotive—meet identical electrical and mechanical specifications for resistance value, tolerance, power rating, package, and operating temperature range. The AEC-Q200 qualification represents an additional feature that does not prevent use in non-automotive applications.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only the manufacturing process and handling logistics. Electrical and mechanical performance is identical between Cut Tape and Tape & Reel formats of the same component. Selection should be based on your assembly equipment compatibility and supply chain requirements.

Q: Why is MCR03ERTF2152 listed as a substitute if it is discontinued?

A: MCR03ERTF2152 is electrically and mechanically equivalent and may be available from existing inventory channels. However, it should be selected only when confirmed inventory is available and when long-term supply continuity is not a design requirement. For new designs requiring sustained supply, select from Active status parts.

Q: Can I use CRCW060321K5FKEA or ERJ-3EKF2152V in place of RC1608F2152CS?

A: Yes. Both parts are functionally equivalent with identical electrical specifications and Active product status. CRCW060321K5FKEA (Vishay Dale) offers 64,207 pieces in inventory, and ERJ-3EKF2152V (Panasonic Electronic Components) offers 74,170 pieces in inventory. Both are supplied in Tape & Reel format.

Q: What parameters must match exactly for a part to be considered a true substitute?

A: The following parameters must match exactly: resistance value (21.5 kOhms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and number of terminations (2). All listed substitute parts meet these requirements.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-0721K5L (YAGEO) has the highest inventory availability at 1,695,486 pieces in stock, followed by CRCW060321K5FKEA (Vishay Dale) at 64,207 pieces.
