Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 1.69 MOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.1W minimum (exact match)
• Temperature coefficient: ±100ppm/°C or ±200ppm/°C (both acceptable for general applications)
• Operating temperature range: -55°C to 155°C minimum (exact match)

Mechanical Equivalence Requirements:

• Package type: 0603 (1608 Metric) (exact match)
• Termination count: 2 (exact match)
• Moisture resistance: Required
• MSL rating: Level 1 or better (exact match)

Compliance Equivalence Requirements:

• RoHS3 compliance (mandatory)
• REACH unaffected status (mandatory)
• Packaging: Tape & Reel format (standard for production use)

All substitute parts listed meet these criteria. Automotive-grade variants (AEC-Q200 rated) represent functional upgrades with enhanced reliability qualification but maintain full backward compatibility with standard applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (RC0603FR-071M69L by YAGEO): This part provides direct functional equivalence to the RC1608F1694CS. Both components share identical electrical specifications, temperature coefficient, and package dimensions. Selection is appropriate for applications requiring standard industrial-grade thick film resistors without automotive qualification requirements. High inventory availability (27,518 units) supports production continuity.

Automotive-Grade Upgrade (RMCF0603FT1M69 by Stackpole Electronics Inc): This variant introduces AEC-Q200 automotive qualification while maintaining all core electrical parameters. The temperature coefficient specification increases to ±200ppm/°C, which remains within acceptable tolerance for most circuit applications. This upgrade is suitable for automotive, industrial control, and mission-critical applications requiring enhanced reliability qualification. Stackpole RMCF series components are qualified for automotive environments per AEC-Q200 standard.

Automotive-Grade Upgrade (CRCW06031M69FKEA by Vishay Dale): This alternative provides AEC-Q200 automotive qualification with temperature coefficient of ±100ppm/°C, matching the original Samsung specification. Vishay Dale CRCW series components maintain identical electrical performance while offering automotive-grade reliability certification. Physical dimensions show minor variation (1.55mm x 0.85mm vs. 1.60mm x 0.80mm) and seated height of 0.020" (0.50mm) versus 0.022" (0.55mm), which remain within standard PCB assembly tolerances for 0603 package format.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory compliance across global markets.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M69L by YAGEO be used as a direct replacement for RC1608F1694CS?

A: Yes. Both components share identical resistance value (1.69 MOhms), tolerance (±1%), power rating (0.1W), package format (0603/1608 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Electrical and mechanical compatibility is complete. Substitution is valid for all applications not requiring automotive qualification.

Q: What is the difference between standard and automotive-grade variants?

A: Automotive-grade variants (RMCF0603FT1M69 and CRCW06031M69FKEA) carry AEC-Q200 qualification, indicating enhanced reliability testing and qualification for automotive environments. RMCF0603FT1M69 specifies ±200ppm/°C temperature coefficient, while CRCW06031M69FKEA maintains ±100ppm/°C. Both are functionally equivalent to the standard RC1608F1694CS for general applications but provide additional reliability assurance for automotive and mission-critical use.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within 0603 package tolerance. RC1608F1694CS and RC0603FR-071M69L specify 1.60mm x 0.80mm dimensions. RMCF0603FT1M69 and CRCW06031M69FKEA specify 1.55mm x 0.80mm and 1.55mm x 0.85mm respectively. Seated height varies between 0.022" (0.55mm) and 0.020" (0.50mm). These variations remain within standard 0603 package specifications and do not affect PCB assembly compatibility.

Q: Which substitute part offers the best inventory availability?

A: RC0603FR-071M69L by YAGEO provides the highest inventory level at 27,518 units, followed by CRCW06031M69FKEA (17,782 units) and RMCF0603FT1M69 (13,038 units). Selection based on inventory should be balanced against application requirements for automotive qualification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RC0603FR-071M69L, RMCF0603FT1M69, and CRCW06031M69FKEA) maintain ROHS3 compliance and REACH unaffected status, matching the regulatory compliance profile of the original RC1608F1694CS.

Q: Can automotive-grade parts be used in non-automotive applications?

A: Yes. Automotive-grade components (AEC-Q200 rated) are fully compatible with standard industrial and consumer applications. The enhanced qualification represents a reliability upgrade and does not restrict use in non-automotive circuits. Substitution in either direction (standard to automotive or automotive to standard) is valid based on application requirements.
