Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F1214CS is determined by strict equivalence across the following critical parameters: resistance value (1.21 MOhms), tolerance (±1%), power rating (0.1W), package format (0603/1608 Metric), composition (thick film), operating temperature range (-55°C to 155°C), and regulatory compliance (RoHS3). All identified substitute parts match these core electrical and mechanical specifications. Variations in secondary parameters such as temperature coefficient, physical dimensions within tolerance, packaging format (Tape & Reel versus Cut Tape), and optional automotive certifications do not disqualify substitution but may influence selection based on application requirements and supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

RC0603FR-071M21L (YAGEO): Direct equivalent with identical electrical specifications and Active product status. Tape & Reel packaging matches the original part. High inventory availability (464,301 pcs) supports supply chain continuity. Recommended as primary substitute for standard applications.

RMCF0603FT1M21 (Stackpole Electronics Inc): Functionally equivalent with Active product status and automotive AEC-Q200 certification. Temperature coefficient of ±200 ppm/°C represents a secondary parameter variation from the original ±100 ppm/°C specification. Select this part for applications requiring automotive-grade qualification or when AEC-Q200 compliance is mandated by design requirements.

CRCW06031M21FKEA (Vishay Dale): Functionally equivalent with Active product status and automotive AEC-Q200 certification. Temperature coefficient matches the original specification at ±100 ppm/°C. Physical dimensions vary slightly (1.55mm x 0.85mm versus 1.60mm x 0.80mm) and seated height is 0.50mm versus 0.55mm. Select for automotive applications or when Vishay Dale supply chain preference exists.

MCR03ERTF1214 (Rohm Semiconductor): Functionally equivalent but marked as Discontinued at DiGi Electronics. Electrical specifications match the original part. Cut Tape packaging differs from Tape & Reel format. Avoid for new designs; consider only for legacy system maintenance where supply exists through alternative channels.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M21L replace RC1608F1214CS in all applications?

A: Yes. RC0603FR-071M21L matches all critical electrical parameters (1.21 MOhms, ±1% tolerance, 0.1W power rating), operates across the identical temperature range (-55°C to 155°C), and maintains RoHS3 compliance. Both parts use thick film composition and 0603 package format. Tape & Reel packaging is identical.

Q: What is the difference between RMCF0603FT1M21 and the original RC1608F1214CS?

A: The primary difference is temperature coefficient: RMCF0603FT1M21 specifies ±200 ppm/°C while RC1608F1214CS specifies ±100 ppm/°C. RMCF0603FT1M21 includes automotive AEC-Q200 certification. All other electrical specifications and operating parameters are identical. The higher temperature coefficient may affect precision applications requiring tight temperature stability.

Q: Why is MCR03ERTF1214 listed as discontinued?

A: MCR03ERTF1214 is marked as Discontinued at DiGi Electronics, indicating reduced availability through primary distribution channels. While electrical specifications remain equivalent, this part should not be selected for new designs. Existing inventory may be available through secondary sources for legacy system support.

Q: Are there packaging differences between substitute parts?

A: Yes. RC1608F1214CS, RC0603FR-071M21L, RMCF0603FT1M21, and CRCW06031M21FKEA use Tape & Reel (TR) packaging. MCR03ERTF1214 uses Cut Tape (CT) & Digi-Reel® packaging. All parts use identical 0603 (1608 Metric) case format and are compatible with standard pick-and-place assembly equipment. Packaging format selection depends on production volume and assembly line configuration.

Q: Which substitute part should be selected for automotive applications?

A: RMCF0603FT1M21 and CRCW06031M21FKEA both carry automotive AEC-Q200 certification. CRCW06031M21FKEA maintains the original ±100 ppm/°C temperature coefficient, while RMCF0603FT1M21 specifies ±200 ppm/°C. Select based on temperature stability requirements and preferred supplier relationship.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (RC0603FR-071M21L, MCR03ERTF1214, RMCF0603FT1M21, and CRCW06031M21FKEA) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RC1608F1214CS specification.
