RC1608F6810CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F6810CS is a 681 Ohms ±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 and is RoHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). The part is widely used in general-purpose electronic applications requiring precision resistive elements with moisture resistance and stable temperature characteristics across industrial temperature ranges.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization requires alternative sourcing, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F6810CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 681 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to +155°C

Mechanical Parameters (Must Match Exactly):

• Package type: 0603 (1608 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters:

• RoHS3 compliance status
• REACH compliance status

All substitute parts listed in this reference meet these exact specifications. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) does not affect electrical or mechanical compatibility and represents a logistics variable only. Additional features such as Automotive AEC-Q200 certification present in some substitute parts exceed the base specification and do not prevent substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Compliance Match):

The following parts are direct substitutes meeting all electrical, mechanical, and compliance requirements identical to RC1608F6810CS:

• CR0603-FX-6810ELF (Bourns Inc.) – Tape & Reel packaging, ROHS3 compliant, 43,638 units in stock
• RC0603FR-07681RL (YAGEO) – Tape & Reel packaging, ROHS3 compliant, 69,652 units in stock
• ERJ-3EKF6810V (Panasonic Electronic Components) – Tape & Reel packaging, ROHS3 compliant, 107,719 units in stock
• RMCF0603FT681R (Stackpole Electronics Inc) – Tape & Reel packaging, ROHS3 compliant, 206,606 units in stock

These parts carry identical electrical specifications and RoHS3 compliance status. Selection among these options may be based on supply availability, lead time, or established supplier relationships.

Automotive-Qualified Substitutes (Enhanced Specification):

The following parts meet all base specifications and additionally carry Automotive AEC-Q200 certification:

• AC0603FR-07681RL (YAGEO) – Tape & Reel packaging, ROHS3 compliant, AEC-Q200 rated, 15,969 units in stock
• CRCW0603681RFKEA (Vishay Dale) – Cut Tape & Digi-Reel packaging, ROHS3 compliant, AEC-Q200 rated, 1,982 units in stock
• RMCF0603FG681R (Stackpole Electronics Inc) – Cut Tape packaging, ROHS3 compliant, AEC-Q200 rated, 23,071 units in stock

These parts are suitable for automotive and industrial applications requiring enhanced reliability qualification. AEC-Q200 certification does not prevent use in non-automotive applications.

Non-Compliant Substitute (Restricted Use):

• CRCW0603681RFKTA (Vishay Dale) – Tape & Reel packaging, RoHS non-compliant, REACH affected, 5,984 units in stock

This part meets all electrical and mechanical specifications but does not comply with RoHS3 requirements. Use is restricted to applications and jurisdictions where RoHS3 compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F6810CS with any of the listed parts without circuit redesign?

A: Yes. All listed parts except CRCW0603681RFKTA meet identical electrical specifications (681 Ω ±1%, 0.1W, ±100ppm/°C, -55°C to +155°C) and mechanical package (0603 Thick Film). Direct substitution is electrically and mechanically compatible. CRCW0603681RFKTA is electrically compatible but RoHS non-compliant.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel and Cut Tape represent different supply formats for automated assembly. Tape & Reel provides continuous reel format for high-speed pick-and-place equipment. Cut Tape provides individual tape segments for lower-volume or manual assembly. Both formats contain identical components. Selection depends on assembly equipment capability and order volume requirements.

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

A: Yes. AEC-Q200 certification represents an enhanced reliability qualification exceeding base specifications. Parts carrying this certification are fully compatible with non-automotive applications and may be used as direct substitutes without restriction.

Q: Why is CRCW0603681RFKTA listed if it is RoHS non-compliant?

A: CRCW0603681RFKTA meets all electrical and mechanical specifications. It is included for reference in applications and jurisdictions where RoHS3 compliance is not required. For new designs and applications subject to RoHS3 regulations, use ROHS3-compliant alternatives.

Q: Can I mix different manufacturers' parts in the same circuit board assembly?

A: Yes. All listed ROHS3-compliant parts meet identical electrical and mechanical specifications and are interchangeable. Mixing manufacturers in the same assembly is electrically and mechanically valid. Procurement and supply chain considerations may influence this decision.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. These components do not require special moisture-controlled storage conditions and can be stored under standard industrial conditions indefinitely.

Q: Are there any dimensional differences between substitute parts?

A: All parts conform to 0603 (1608 Metric) package specification. Minor dimensional variations exist within tolerance (height range 0.020" to 0.022", length range 0.061" to 0.063", width range 0.031" to 0.033"). These variations are within standard PCB design tolerances and do not affect assembly or performance.
