RC1608F2494CS Equivalent & Substitute Parts

Part Overview

The RC1608F2494CS is a 2.49 MOhm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This surface mount device is rated for 0.1W (1/10W) power dissipation and operates across the temperature range of -55°C to 155°C. The component features moisture-resistant construction with unlimited moisture sensitivity level (MSL 1) and maintains active product status with full RoHS3 compliance.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package dimensions and termination count), and environmental operating parameters. Substitute components enable design flexibility, supply chain optimization, and application-specific feature selection while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F2494CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2.49 MOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)

Mechanical Compatibility Requirements:

• Package type: 0603 (1608 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 0603 footprint

Environmental & Compliance Requirements:

• Operating temperature range: -55°C to 155°C (minimum)
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Thick film composition

All identified substitute parts meet these core requirements. Variations in temperature coefficient, packaging format (Cut Tape vs. Tape & Reel), and optional automotive certifications (AEC-Q200) represent secondary differentiators that do not affect functional substitution but may influence application-specific selection criteria.

Parameter Comparison

Engineering Selection Recommendations

RC0603FR-072M49L (YAGEO) is a direct functional equivalent with identical electrical specifications and environmental ratings. This substitute maintains the ±100ppm/°C temperature coefficient of the original part and offers the largest available inventory (190,850 pcs). Selection of this part is appropriate for applications requiring standard industrial-grade thick film resistors without automotive qualification requirements.

RMCF0603FT2M49 (Stackpole Electronics Inc) qualifies as an upgrade substitute due to AEC-Q200 automotive qualification. This part is suitable for automotive and high-reliability applications. The temperature coefficient specification of ±200ppm/°C represents a relaxation from the original ±100ppm/°C; this difference is acceptable in applications where the broader tolerance does not compromise circuit performance. Inventory availability is substantial at 116,799 pcs.

CRCW06032M49FKEA (Vishay Dale) qualifies as a similar substitute with AEC-Q200 automotive qualification and maintains the ±100ppm/°C temperature coefficient matching the original part. Physical dimensions show minor variations (0.061" L x 0.033" W vs. 0.063" L x 0.031" W for the original), which remain within 0603 package compatibility. This part is suitable for automotive applications requiring temperature coefficient equivalence. Inventory availability is 30,195 pcs.

All substitute parts maintain active product status, full RoHS3 compliance, and unlimited moisture sensitivity level (MSL 1). Selection between substitutes should be based on application requirements (automotive vs. industrial), temperature coefficient tolerance, and packaging format preference (Cut Tape vs. Tape & Reel).

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-072M49L (YAGEO) be used as a direct replacement for RC1608F2494CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (2.49 MOhms, ±1%, 0.1W), operate across the same temperature range (-55°C to 155°C), and are packaged in 0603 (1608 Metric) format with two terminations. Temperature coefficient, RoHS compliance, and moisture sensitivity level are equivalent. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and manufacturer.

Q: What is the difference between the automotive-rated substitutes (RMCF0603FT2M49 and CRCW06032M49FKEA) and the standard industrial part?

A: RMCF0603FT2M49 and CRCW06032M49FKEA carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental stress testing standards. The original RC1608F2494CS and YAGEO RC0603FR-072M49L do not carry this certification. Automotive-rated parts are required for applications in automotive systems; standard industrial parts are suitable for consumer and industrial electronics.

Q: Does the ±200ppm/°C temperature coefficient of RMCF0603FT2M49 affect substitution compatibility?

A: The ±200ppm/°C specification represents a relaxation from the original ±100ppm/°C. This difference affects long-term stability and temperature-dependent drift characteristics. Substitution is valid only if the application circuit design tolerates the broader temperature coefficient. For precision analog circuits with tight temperature stability requirements, CRCW06032M49FKEA (±100ppm/°C) or RC0603FR-072M49L (±100ppm/°C) are preferred.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist. The original RC1608F2494CS specifies 0.063" L x 0.031" W (1.60mm x 0.80mm). RMCF0603FT2M49 and CRCW06032M49FKEA specify 0.061" L x 0.031" W (1.55mm x 0.80mm) and 0.061" L x 0.033" W (1.55mm x 0.85mm) respectively. All dimensions remain within 0603 package tolerance and are compatible with standard 0603 PCB footprints. Height specifications are equivalent across all parts (0.020" to 0.022" maximum seated height).

Q: What packaging format differences exist, and does this affect substitution?

A: The original RC1608F2494CS is supplied in Cut Tape (CT) format. All substitute parts are supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical or mechanical compatibility. Cut Tape format is typically used for small-quantity orders or manual assembly; Tape & Reel format is standard for automated pick-and-place assembly. Selection depends on manufacturing process requirements, not circuit functionality.

Q: Which substitute part offers the best inventory availability?

A: RC0603FR-072M49L (YAGEO) offers the highest inventory level at 190,850 pcs. RMCF0603FT2M49 (Stackpole) provides 116,799 pcs, and CRCW06032M49FKEA (Vishay Dale) provides 30,195 pcs. Inventory levels support supply chain planning and lead-time optimization.
