RC1608F2554CS Equivalent & Substitute Parts

Part Overview

The RC1608F2554CS is a 2.55 MOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) surface mount package format. This component is rated for 0.1W (1/10W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is actively produced and maintains ROHS3 compliance with Moisture Sensitivity Level 1 (unlimited shelf life). Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental ratings to ensure direct functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1608F2554CS is determined by strict equivalence across the following critical parameters: resistance value (2.55 MOhms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). All identified substitute parts match these core electrical and mechanical specifications. Variations in temperature coefficient (±100ppm/°C versus ±200ppm/°C) and dimensional tolerances (length and height) are noted but do not prevent functional substitution when the primary electrical parameters and package footprint remain identical. Automotive-grade variants (AEC-Q200 rated) are included as substitutes where the application permits enhanced reliability specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (RC0603FR-072M55L, RMCF0603FT2M55, and CRCW06032M55FKEA) are functionally equivalent to the RC1608F2554CS for standard applications. Selection between these options depends on application-specific requirements:

RC0603FR-072M55L (YAGEO) provides direct electrical and thermal equivalence with identical temperature coefficient (±100ppm/°C) and moisture-resistant thick film construction. This part is suitable for general-purpose applications requiring standard industrial specifications.

RMCF0603FT2M55 (Stackpole Electronics Inc) is qualified to AEC-Q200 automotive standards and is appropriate for automotive and high-reliability applications. The temperature coefficient is ±200ppm/°C, which remains within acceptable tolerance for most circuit designs but should be verified for precision analog applications.

CRCW06032M55FKEA (Vishay Dale) is also AEC-Q200 qualified and maintains the ±100ppm/°C temperature coefficient matching the original part. This option is suitable for automotive applications requiring enhanced reliability specifications without compromise to temperature stability.

All parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature ranges. Selection should be based on supply chain availability, cost considerations, and specific application requirements for automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-072M55L be used as a direct replacement for RC1608F2554CS?

A: Yes. Both parts share identical electrical specifications (2.55 MOhms, ±1% tolerance, 0.1W power rating), package format (0603), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). The temperature coefficient is also identical at ±100ppm/°C.

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

A: RMCF0603FT2M55 and CRCW06032M55FKEA are qualified to AEC-Q200 automotive standards, indicating enhanced reliability testing and qualification for automotive applications. The RMCF variant has a temperature coefficient of ±200ppm/°C, while the CRCW maintains ±100ppm/°C. Both are suitable for automotive use; selection depends on temperature stability requirements and supply availability.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The RC1608F2554CS and RC0603FR-072M55L are specified at 0.063" L x 0.031" W (1.60mm x 0.80mm). The RMCF0603FT2M55 is 0.061" L x 0.031" W (1.55mm x 0.80mm). The CRCW06032M55FKEA is 0.061" L x 0.033" W (1.55mm x 0.85mm). These variations are within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All parts, including the original RC1608F2554CS, are rated MSL 1 (Unlimited), indicating no moisture sensitivity concerns and unlimited shelf life under standard storage conditions.

Q: Which substitute part should be selected for cost optimization?

A: Selection based on cost should consider current inventory levels and supplier pricing. YAGEO RC0603FR-072M55L offers standard industrial specifications. Automotive-grade parts (Stackpole RMCF0603FT2M55 and Vishay Dale CRCW06032M55FKEA) may command a price premium due to AEC-Q200 qualification but are necessary for automotive applications.

Q: Are all parts actively manufactured?

A: Yes. All four parts (RC1608F2554CS, RC0603FR-072M55L, RMCF0603FT2M55, and CRCW06032M55FKEA) maintain Active product status with current manufacturing and distribution.
