Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F1874CS is determined by strict alignment of the following parameters:

Core Electrical Parameters (Non-Negotiable):

• Resistance value: 1.87 MOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Composition: Thick Film

Physical Parameters (Non-Negotiable):

• Package / Case: 0603 (1608 Metric)
• Number of Terminations: 2

Environmental & Compliance Parameters (Required):

• Operating Temperature Range: -55°C to 155°C (minimum)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Secondary Parameters (Allowable Variation):

• Temperature Coefficient: ±100ppm/°C to ±200ppm/°C
• Physical dimensions: Minor variations within 0603 package specification
• Automotive qualification (AEC-Q200): Optional enhancement

All identified substitute parts meet or exceed these criteria. Substitutes are classified as Direct (equivalent specifications), Upgrade (enhanced automotive qualification), or Similar (minor dimensional variation with enhanced qualification).

Engineering Selection Recommendations

RC0603FR-071M87L (YAGEO) - Direct Equivalent: This part is functionally equivalent to the RC1608F1874CS with identical electrical specifications, temperature coefficient, and environmental ratings. Selection is appropriate for applications requiring standard industrial-grade thick film resistors without automotive qualification requirements. Inventory availability is 16,857 pieces.

RMCF0603FT1M87 (Stackpole Electronics Inc) - Upgrade Option: This part provides AEC-Q200 automotive qualification with identical core electrical parameters. The temperature coefficient is ±200ppm/°C compared to ±100ppm/°C in the original part, which remains within acceptable tolerance for most applications. Selection is appropriate for automotive or mission-critical applications requiring enhanced reliability qualification. Inventory availability is 78,176 pieces.

CRCW06031M87FKEA (Vishay Dale) - Upgrade Option: This part provides AEC-Q200 automotive qualification with temperature coefficient of ±100ppm/°C, matching the original specification. Physical dimensions show minor variation (1.55mm x 0.85mm vs. 1.60mm x 0.80mm) and seated height of 0.020" (0.50mm) vs. 0.022" (0.55mm), which remain within 0603 package tolerance. Selection is appropriate for automotive applications requiring enhanced reliability with matched temperature coefficient performance. Inventory availability is 66,143 pieces.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range. Selection among these options is based on application requirements (automotive vs. standard), temperature coefficient precision needs, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M87L (YAGEO) be used as a direct replacement for RC1608F1874CS (Samsung)?

A: Yes. Both parts share identical resistance value (1.87 MOhms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating. No design modification is required.

Q: What is the difference between the RMCF0603FT1M87 and CRCW06031M87FKEA substitutes?

A: Both parts provide AEC-Q200 automotive qualification. The primary difference is temperature coefficient: RMCF0603FT1M87 has ±200ppm/°C while CRCW06031M87FKEA has ±100ppm/°C. Physical dimensions also vary slightly within 0603 package specification. For applications requiring tighter temperature coefficient control, CRCW06031M87FKEA is preferred.

Q: Are automotive-qualified parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. AEC-Q200 qualified parts (RMCF0603FT1M87 and CRCW06031M87FKEA) meet or exceed all specifications of standard industrial-grade parts. They can be used in any application where the original RC1608F1874CS is specified. Automotive qualification represents enhanced reliability testing and is not restrictive for other applications.

Q: Do all substitute parts use the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging in 0603 (1608 Metric) format, identical to the original RC1608F1874CS. No changes to assembly or handling procedures are required.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 rating indicates unlimited shelf life without moisture baking requirements. All parts in this comparison, including the original and all substitutes, carry MSL 1 rating. This means standard storage conditions are acceptable without special moisture control procedures.

Q: Can these parts be intermixed in the same production batch?

A: Yes. All parts meet identical electrical specifications (1.87 MOhms ±1%, 0.1W), package format (0603), and environmental compliance (ROHS3, MSL 1). They are functionally interchangeable at the circuit level. However, design documentation should be updated to reflect any part number changes for traceability and future maintenance purposes.
