RC1608F7871CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F7871CS is a 7.87 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity rating).

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications permit alternative qualified sources meeting identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F7871CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 7.87 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these mandatory parameters. Substitute parts are grouped into two categories:

Direct Substitutes maintain identical specifications including standard industrial moisture-resistant construction without automotive qualification.

Similar Substitutes meet all mandatory electrical and mechanical parameters but include additional automotive AEC-Q200 qualification, which provides enhanced reliability for automotive applications while maintaining full compatibility with standard industrial designs.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: The CR0603-FX-7871ELF (Bourns Inc.) and RC0603FR-077K87L (YAGEO) are direct substitutes with identical specifications to the RC1608F7871CS. Both maintain Active product status and full ROHS3 compliance. The RC0603FR-077K87L offers significantly higher inventory availability (200,622 pcs) compared to the primary part (801 pcs), making it suitable for high-volume procurement scenarios.

For Automotive or Enhanced Reliability Applications: The AC0603FR-077K87L (YAGEO), CRCW06037K87FKEA (Vishay Dale), ERJ-3EKF7871V (Panasonic), and RMCF0603FT7K87 (Stackpole Electronics) all meet mandatory parameters while providing AEC-Q200 automotive qualification. These parts are suitable for designs requiring automotive-grade components or applications demanding enhanced reliability margins. The RMCF0603FT7K87 provides the highest inventory level (69,850 pcs) among automotive-qualified options.

Supply Chain Optimization: All listed substitutes maintain Active product status and ROHS3 compliance. Selection should prioritize inventory availability and lead time requirements specific to procurement timelines.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F7871CS with any of the listed parts in my design?

A: Yes. All listed parts meet identical electrical specifications (7.87 kOhms ±1%, 0.1W, ±100ppm/°C) and mechanical requirements (0603 package, -55°C to 155°C operating range). Direct substitution is electrically and mechanically compatible without design modification.

Q: What is the difference between "Direct Substitutes" and "Similar Substitutes"?

A: Direct substitutes (CR0603-FX-7871ELF, RC0603FR-077K87L) match all specifications including standard moisture-resistant construction. Similar substitutes include additional AEC-Q200 automotive qualification, which provides enhanced reliability testing and qualification for automotive applications. All parts are functionally equivalent for standard industrial use.

Q: Are the automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents additional testing and quality assurance beyond standard industrial requirements. These parts are fully compatible with non-automotive designs and may be used as direct substitutes without restriction.

Q: Does package size vary between these substitutes?

A: All parts use the 0603 (1608 Metric) package. Physical dimensions are nominally identical (0.063" L x 0.031" W / 1.60mm x 0.80mm), with maximum seated height of 0.022" (0.55mm). Minor dimensional variations within standard tolerances do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the best supply availability?

A: The RC0603FR-077K87L (YAGEO) offers the highest inventory level at 200,622 pcs, followed by RMCF0603FT7K87 (Stackpole) at 69,850 pcs for automotive-qualified applications.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the primary part's environmental and regulatory qualifications.
