Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on substitution relationship type:

Direct Substitutes maintain identical electrical and mechanical specifications with equivalent or superior environmental ratings:

• CR0805-FX-8661ELF (Bourns Inc.)
• ERJ-6ENF8661V (Panasonic Electronic Components)
• KTR10EZPF8661 (Rohm Semiconductor)
• RC0805FR-078K66L (YAGEO)
• RMCF0805FT8K66 (Stackpole Electronics Inc)

Similar Substitutes meet core electrical specifications and package requirements with variations in features or product status:

• CRCW08058K66FKEA (Vishay Dale)
• MCR10ERTF8661 (Rohm Semiconductor) - Discontinued at DiGi Electronics
• RMCS0805FT8K66 (Stackpole Electronics Inc)

Substitution eligibility is determined by the following parameters: Resistance value (8.66 kOhms), Tolerance (±1%), Power rating (0.125W), Package format (0805), Composition (Thick Film), Temperature coefficient (±100ppm/°C), Operating temperature range (-55°C to 155°C), Moisture sensitivity level (1), and RoHS compliance (ROHS3).

Engineering Selection Recommendations

Primary Selection Candidates (Active Status, Direct Substitutes):

CR0805-FX-8661ELF, ERJ-6ENF8661V, KTR10EZPF8661, RC0805FR-078K66L, and RMCF0805FT8K66 are direct substitutes with active product status. All maintain identical electrical specifications and ROHS3 compliance. Selection among these parts depends on application requirements: ERJ-6ENF8661V, KTR10EZPF8661, RMCF0805FT8K66, and CRCW08058K66FKEA carry AEC-Q200 automotive qualification for applications requiring automotive-grade reliability. RMCS0805FT8K66 provides anti-sulfur construction for environments with sulfur exposure risk.

Secondary Selection Candidates (Similar Substitutes):

MCR10ERTF8661 is discontinued at DiGi Electronics and should not be selected for new designs. CRCW08058K66FKEA and RMCS0805FT8K66 are active but classified as similar substitutes due to feature variations. These parts maintain full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC2012F8661CS be replaced with CR0805-FX-8661ELF?

A: Yes. CR0805-FX-8661ELF is a direct substitute. Both parts share identical resistance (8.66 kOhms), tolerance (±1%), power rating (0.125W), package format (0805), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and ROHS3 compliance. Physical dimensions are equivalent with maximum seated heights of 0.65mm and 0.60mm respectively.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (CR0805-FX-8661ELF, ERJ-6ENF8661V, KTR10EZPF8661, RC0805FR-078K66L, RMCF0805FT8K66) maintain all electrical and mechanical specifications with active product status. Similar substitutes (CRCW08058K66FKEA, MCR10ERTF8661, RMCS0805FT8K66) meet core specifications but may have feature variations or discontinued status.

Q: Are automotive-qualified parts (AEC-Q200) interchangeable with standard parts?

A: Yes, for applications not requiring automotive qualification. AEC-Q200 parts (ERJ-6ENF8661V, KTR10EZPF8661, RMCF0805FT8K66, CRCW08058K66FKEA) meet or exceed standard specifications and are suitable for general industrial applications. However, standard parts should not replace AEC-Q200 parts in automotive designs.

Q: What is the significance of anti-sulfur construction in RMCS0805FT8K66?

A: Anti-sulfur construction (RMCS0805FT8K66) provides enhanced resistance to sulfur-containing environments. This feature is relevant for applications in industrial or marine settings with sulfur exposure. For standard environments, this feature is not required.

Q: Can I use MCR10ERTF8661 for new designs?

A: No. MCR10ERTF8661 is discontinued at DiGi Electronics. For new designs, select from active status parts: CR0805-FX-8661ELF, ERJ-6ENF8661V, KTR10EZPF8661, RC0805FR-078K66L, RMCF0805FT8K66, CRCW08058K66FKEA, or RMCS0805FT8K66.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the RC2012F8661CS specification.

Q: What packaging formats are available for these substitutes?

A: All substitute parts are available in 0805 (2012 Metric) package. Packaging delivery formats vary: most are supplied in Tape & Reel (TR) format; ERJ-6ENF8661V and MCR10ERTF8661 are supplied in Cut Tape (CT) & Digi-Reel® format.
