RC1608F2672CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F2672CS is a 26.7 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format with 0.1W power rating. This component is classified as Active product status with moisture-resistant construction and unlimited moisture sensitivity level (MSL 1). The part is ROHS3 compliant and REACH unaffected, suitable for general industrial and commercial applications requiring precision resistive elements in compact surface-mount form factors.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required, or when design specifications permit selection from multiple qualified suppliers offering identical or functionally equivalent electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F2672CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 26.7 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant minimum
• Moisture Sensitivity Level: MSL 1 (Unlimited) minimum

Substitute parts are categorized as follows:

Direct Substitutes: Parts meeting all electrical, mechanical, and compliance requirements with identical functional performance. Packaging format may differ (Tape & Reel vs. Cut Tape).

Upgrade Substitutes: Parts meeting all core requirements but with additional features or certifications (such as Automotive AEC-Q200 qualification) that provide enhanced reliability for specialized applications while maintaining backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Substitutes (Recommended for Standard Applications):

CR0603-FX-2672ELF (Bourns Inc.) and RC0603FR-0726K7L (YAGEO) are fully qualified direct substitutes with identical electrical and mechanical specifications. Both maintain Active product status with ROHS3 compliance and MSL 1 rating. Selection between these and the primary part depends on supplier availability and packaging preference (Tape & Reel vs. Cut Tape & Digi-Reel).

Alternative Direct Substitutes (Active Status):

AC0603FR-0726K7L (YAGEO), CRCW060326K7FKEA (Vishay Dale), ERJ-3EKF2672V (Panasonic Electronic Components), and RMCF0603FT26K7 (Stackpole Electronics Inc) are all Active products meeting identical electrical and mechanical requirements. These parts include Automotive AEC-Q200 certification, which provides enhanced reliability qualification for automotive and high-reliability applications while maintaining full backward compatibility with standard industrial designs.

Discontinued Parts (Not Recommended for New Designs):

MCR03ERTF2672 (Rohm Semiconductor) and CRCW060326K7FKEB (Vishay Dale) are discontinued at DiGi Electronics. While electrically and mechanically equivalent, these parts should not be selected for new designs due to limited future availability.

Selection Criteria:

• For new designs: Select from Active status parts (CR0603-FX-2672ELF, RC0603FR-0726K7L, AC0603FR-0726K7L, CRCW060326K7FKEA, ERJ-3EKF2672V, or RMCF0603FT26K7)
• For automotive or high-reliability applications: Select from AEC-Q200 qualified parts (AC0603FR-0726K7L, CRCW060326K7FKEA, ERJ-3EKF2672V, or RMCF0603FT26K7)
• For standard industrial applications: Any Active status part is acceptable
• Packaging format selection (Tape & Reel vs. Cut Tape & Digi-Reel) depends on assembly equipment and procurement workflow requirements

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F2672CS with any of the listed equivalent parts?

A: Yes, all parts listed with Active product status are fully qualified substitutes. They meet identical electrical specifications (26.7 kOhms ±1%, 0.1W, ±100 ppm/°C, -55°C to 155°C), mechanical requirements (0603 package, 2 terminations, thick film composition), and compliance standards (ROHS3, MSL 1). Discontinued parts should not be used for new designs.

Q: What is the difference between Direct Substitutes and Upgrade Substitutes?

A: Direct substitutes (CR0603-FX-2672ELF, RC0603FR-0726K7L) provide identical functionality without additional certifications. Upgrade substitutes include Automotive AEC-Q200 qualification (AC0603FR-0726K7L, CRCW060326K7FKEA, ERJ-3EKF2672V, RMCF0603FT26K7), which certifies enhanced reliability for automotive and high-reliability applications. Upgrade parts are fully backward compatible and can replace standard parts in any application.

Q: Does packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) affect electrical performance?

A: No. Packaging format affects only procurement and assembly logistics, not electrical or mechanical performance. Both formats contain identical components. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I use discontinued parts (MCR03ERTF2672, CRCW060326K7FKEB) in existing designs?

A: Electrically and mechanically, yes. However, discontinued parts have limited future availability. For ongoing production or new designs, select from Active status parts to ensure long-term supply chain reliability.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. The component can be stored indefinitely without special moisture control measures, simplifying inventory management and reducing production constraints.

Q: Are there any dimensional differences between substitute parts?

A: All parts use 0603 (1608 Metric) package format. Minor dimensional variations exist within tolerance (for example, CRCW series shows 0.061" L x 0.033" W vs. standard 0.063" L x 0.031" W), but these fall within PCB footprint design tolerances and do not affect interchangeability.

Q: Which substitute should I select for automotive applications?

A: For automotive applications, select from AEC-Q200 qualified parts: AC0603FR-0726K7L (YAGEO), CRCW060326K7FKEA (Vishay Dale), ERJ-3EKF2672V (Panasonic Electronic Components), or RMCF0603FT26K7 (Stackpole Electronics Inc). These parts meet automotive reliability standards while maintaining full electrical and mechanical equivalence.
