Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F274CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 270 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package format: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Parts are further categorized as Direct Substitutes (functionally identical with standard industrial specifications) or Upgrade Substitutes (identical electrical and mechanical specifications with enhanced certifications such as Automotive AEC-Q200 qualification).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Standard Industrial Applications):

CR0603-FX-2703ELF (Bourns Inc.), CRG0603F270K (TE Connectivity Passive Product), and RC0603FR-07270KL (YAGEO) are direct functional equivalents to the RC1608F274CS. These parts share identical electrical specifications, package dimensions, and environmental compliance ratings. Selection among these direct substitutes is based on component availability and supply chain considerations.

Upgrade Substitutes (Enhanced Certifications):

KTR03EZPF2703 (Rohm Semiconductor), AC0603FR-07270KL (YAGEO), CRCW0603270KFKEA (Vishay Dale), ERJ-3EKF2703V (Panasonic Electronic Components), and RMCF0603FT270K (Stackpole Electronics Inc) are qualified to Automotive AEC-Q200 standard while maintaining all electrical and mechanical specifications of the primary part. These components are suitable for applications requiring automotive-grade reliability and qualification documentation. The upgrade substitutes provide enhanced quality assurance and traceability suitable for automotive, industrial control, and mission-critical applications.

Packaging Considerations:

The RC1608F274CS is supplied in Tape & Reel (TR) format. RC0603FR-07270KL is available in Cut Tape (CT) & Digi-Reel® format. CRCW0603270KFKEA is available in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly process requirements and production volume.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-2703ELF replace RC1608F274CS in all applications?

A: Yes. CR0603-FX-2703ELF meets all mandatory electrical and mechanical parameters: 270 kOhms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, RoHS3 compliance, and MSL 1 rating. Both parts feature moisture-resistant thick film composition.

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

A: Automotive AEC-Q200 qualified parts (KTR03EZPF2703, AC0603FR-07270KL, CRCW0603270KFKEA, ERJ-3EKF2703V, RMCF0603FT270K) undergo additional qualification testing and documentation requirements mandated by automotive industry standards. These parts are electrically and mechanically identical to standard parts but carry enhanced reliability certifications. Use automotive-qualified parts when application requirements specify AEC-Q200 compliance or when enhanced traceability documentation is required.

Q: Are there dimensional differences between substitute parts?

A: All substitute parts conform to 0603 (1608 Metric) package specification with maximum seated height of 0.022" (0.55mm). Minor dimensional variations exist within standard tolerance ranges: CRCW0603270KFKEA has dimensions of 0.061" L x 0.033" W (1.55mm x 0.85mm) and height 0.020" (0.50mm); RMCF0603FT270K has dimensions of 0.061" L x 0.031" W (1.55mm x 0.80mm). These variations remain within 0603 package specification and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the highest inventory availability?

A: RC0603FR-07270KL (YAGEO) has the highest documented inventory at 124,369 pieces. ERJ-3EKF2703V (Panasonic) has 67,363 pieces, and RMCF0603FT270K (Stackpole) has 64,038 pieces available. Inventory levels are subject to change and should be verified with current suppliers.

Q: Can I use CRG0603F270K if moisture resistance is not required?

A: Yes. CRG0603F270K meets all mandatory electrical and mechanical specifications. This part does not list moisture-resistant features but maintains all other critical parameters including RoHS3 compliance and MSL 1 rating. Selection depends on application environmental requirements.

Q: What packaging format should I specify for high-volume production?

A: Tape & Reel (TR) format is standard for automated assembly processes. RC1608F274CS, CR0603-FX-2703ELF, KTR03EZPF2703, AC0603FR-07270KL, ERJ-3EKF2703V, and RMCF0603FT270K are available in TR format. Cut Tape (CT) & Digi-Reel® format (RC0603FR-07270KL, CRCW0603270KFKEA) is suitable for lower-volume or mixed-component assembly operations.
