Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

Electrical Parameters: Resistance value (1.62 MOhms), tolerance (±1%), and power rating (0.1W) must be identical. Temperature coefficient variation is permitted within the range of ±100ppm/°C to ±200ppm/°C for automotive-qualified alternatives.

Mechanical Parameters: Package designation must be 0603 (1608 Metric). Physical dimensions may vary within manufacturer tolerances (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height maximum 0.50mm to 0.55mm).

Material & Composition: Thick film construction is required. Moisture-resistant or automotive AEC-Q200 features are compatible enhancements.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating are mandatory. Operating temperature range -55°C to 155°C is standard across all qualified substitutes.

Product Status: Active or recently discontinued parts are acceptable; obsolete parts are excluded.

Four substitute parts meet these criteria and are grouped as follows:

• Direct Equivalent (YAGEO): RC0603FR-071M62L
• Automotive Upgrade (Stackpole): RMCF0603FT1M62
• Automotive Alternatives (Vishay Dale): CRCW06031M62FKEA, CRCW06031M62FKEB

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RC0603FR-071M62L (YAGEO) provides direct electrical and mechanical equivalence with identical temperature coefficient (±100ppm/°C) and superior inventory availability (10976 units). This part maintains all compliance certifications and operating parameters of the original RC1608F1624CS.

For Automotive Applications: RMCF0603FT1M62 (Stackpole Electronics Inc) or CRCW06031M62FKEA (Vishay Dale) are qualified alternatives with AEC-Q200 automotive certification. RMCF0603FT1M62 offers the highest inventory level (91726 units) and is recommended for high-volume automotive designs. CRCW06031M62FKEA provides equivalent automotive qualification with 26790 units in stock.

For Discontinued Part Replacement: CRCW06031M62FKEB (Vishay Dale) is marked as discontinued at DiGi Electronics and should not be selected for new designs or long-term supply chain planning. Existing inventory (20602 units) may be available through alternative distributors but carries supply risk.

Compliance Verification: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and operating temperature range -55°C to 155°C. No additional qualification testing is required for direct substitution in equivalent circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M62L (YAGEO) be used as a direct replacement for RC1608F1624CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (1.62 MOhms ±1%, 0.1W), mechanical package (0603/1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and compliance certifications (ROHS3, MSL 1). Direct substitution is valid without circuit redesign.

Q: What is the difference between RMCF0603FT1M62 and CRCW06031M62FKEA?

A: Both are automotive AEC-Q200 qualified alternatives with identical resistance, tolerance, and power rating. RMCF0603FT1M62 has a temperature coefficient of ±200ppm/°C versus ±100ppm/°C for CRCW06031M62FKEA. RMCF0603FT1M62 offers significantly higher inventory (91726 vs 26790 units). Selection depends on temperature stability requirements and supply availability.

Q: Are there mechanical dimension differences between substitute parts?

A: Minor variations exist within manufacturer tolerances. Length ranges from 1.55mm to 1.60mm, width from 0.80mm to 0.85mm, and height from 0.50mm to 0.55mm. These variations are within standard PCB design tolerances and do not affect placement or functionality in 0603 footprints.

Q: Should CRCW06031M62FKEB be used for new designs?

A: No. CRCW06031M62FKEB is discontinued at DiGi Electronics and carries supply chain risk. For new designs, select RC0603FR-071M62L (standard applications) or RMCF0603FT1M62 (automotive applications).

Q: Do all substitute parts meet the same environmental and compliance standards?

A: Yes. All four substitute parts are ROHS3 compliant, rated MSL 1 (unlimited moisture sensitivity), and operate across -55°C to 155°C. REACH status is unaffected for all parts. Compliance verification is not required for substitution.

Q: What inventory considerations should guide part selection?

A: RMCF0603FT1M62 (Stackpole) provides the highest inventory at 91726 units, followed by CRCW06031M62FKEA (Vishay) at 26790 units and RC0603FR-071M62L (YAGEO) at 10976 units. For high-volume production, RMCF0603FT1M62 is recommended. CRCW06031M62FKEB should be avoided due to discontinued status.
