Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (2.61 kOhms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH Unaffected, MSL 1). Substitute parts are categorized as Direct, Upgrade, or Similar based on product status and feature alignment. Direct substitutes maintain identical specifications and active product status. Upgrade substitutes are discontinued at primary distributors but retain full electrical and mechanical compatibility. Similar substitutes include automotive-grade variants (AEC-Q200 rated) that exceed base specifications while maintaining all core electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred for Standard Applications): CR0603-FX-2611ELF (Bourns Inc.) and RC0603FR-072K61L (YAGEO) are direct functional equivalents with Active product status, identical electrical specifications, and moisture-resistant construction. Both maintain full RoHS3 compliance and MSL 1 rating. Selection between these and the original RC1608F2611CS depends on supply chain availability and packaging format preference (Tape & Reel vs. Cut Tape & Digi-Reel).

Upgrade Substitute (Legacy Replacement): MCR03ERTF2611 (Rohm Semiconductor) provides complete electrical and mechanical compatibility but carries Discontinued status at DiGi Electronics. This part remains suitable for applications where existing inventory exists or where long-term supply is not critical.

Similar Substitutes (Automotive-Grade Applications): AC0603FR-072K61L (YAGEO), CRCW06032K61FKEA (Vishay Dale), ERJ-3EKF2611V (Panasonic Electronic Components), and RMCF0603FT2K61 (Stackpole Electronics Inc) are automotive-qualified variants with AEC-Q200 certification. These parts exceed base specifications while maintaining all core electrical parameters and are suitable for automotive and high-reliability applications. Selection among automotive variants depends on supply availability and specific design requirements for AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F2611CS with any of the listed alternatives without circuit redesign?

A: Yes. All listed substitute parts maintain identical resistance (2.61 kOhms), tolerance (±1%), power rating (0.1W), package format (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Direct electrical and mechanical compatibility is confirmed across all substitutes.

Q: What is the difference between Direct, Upgrade, and Similar substitutes?

A: Direct substitutes (CR0603-FX-2611ELF, RC0603FR-072K61L) are Active products with identical specifications. Upgrade substitutes (MCR03ERTF2611) are discontinued at primary distributors but retain full compatibility. Similar substitutes (AC0603FR-072K61L, CRCW06032K61FKEA, ERJ-3EKF2611V, RMCF0603FT2K61) include automotive AEC-Q200 certification, exceeding base specifications.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to 0603 (1608 Metric) package format. Minor dimensional variations exist: standard parts measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" max height; automotive variants measure 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" max height or 0.061" L x 0.031" W (1.55mm x 0.80mm) with 0.022" max height. These variations remain within 0603 package tolerance and do not affect PCB layout compatibility.

Q: Which substitute should I select for automotive applications?

A: For automotive applications, select from AEC-Q200 qualified variants: AC0603FR-072K61L, CRCW06032K61FKEA, ERJ-3EKF2611V, or RMCF0603FT2K61. All maintain identical electrical specifications while providing automotive-grade reliability certification.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates Unlimited shelf life without moisture-related degradation. All listed parts carry MSL 1 rating, eliminating moisture-related handling restrictions and enabling standard storage and assembly processes.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
