Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F4994CS are qualified based on strict electrical and mechanical parameter matching. All substitute candidates maintain identical resistance value (4.99 MOhms), tolerance (±1%), power rating (0.125W), package format (0805 / 2012 Metric), composition (Thick Film), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1).

Substitutes are grouped into three categories based on provided specifications:

Direct Equivalent: Parts with matching temperature coefficient (±100ppm/°C) and standard moisture-resistant thick film composition.

Upgrade Category: Parts with enhanced automotive qualification (AEC-Q200) suitable for applications requiring higher reliability standards, though temperature coefficient may differ (±200ppm/°C).

Alternative Category: Parts with specialized features (High Voltage capability) while maintaining core electrical parameters and standard temperature coefficient (±100ppm/°C).

All substitute parts are Active product status with identical packaging (Tape & Reel), termination count (2), and compliance status (ROHS3, REACH Unaffected, EAR99).

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-074M99L (YAGEO): Direct equivalent with identical electrical specifications and temperature coefficient (±100ppm/°C). Suitable for applications requiring standard moisture-resistant thick film performance. High inventory availability (52,025 pcs) supports production continuity.

RMCF0805FT4M99 (Stackpole Electronics Inc): Upgrade option with Automotive AEC-Q200 qualification. Temperature coefficient specification differs at ±200ppm/°C. Appropriate for automotive and high-reliability applications where AEC-Q200 certification is required. Largest inventory availability (295,776 pcs) ensures supply security.

CHV0805-FX-4994ELF (Bourns Inc.): Alternative option with High Voltage feature capability. Maintains standard temperature coefficient (±100ppm/°C) and moisture-resistant thick film composition. Suitable for high-voltage circuit applications while preserving electrical compatibility with standard designs.

CRCW08054M99FKEA (Vishay Dale): Upgrade option with Automotive AEC-Q200 qualification. Maintains standard temperature coefficient (±100ppm/°C). Lowest seated height specification (0.020" / 0.50mm) provides advantage for space-constrained PCB layouts. Appropriate for automotive applications requiring AEC-Q200 certification.

All substitute parts maintain Active product status, ROHS3 compliance, and MSL 1 (Unlimited) rating, ensuring regulatory and environmental compatibility with the original RC2012F4994CS specification.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitutability for the RC2012F4994CS?

A: The critical parameters are resistance value (4.99 MOhms), tolerance (±1%), power rating (0.125W), package format (0805 / 2012 Metric), composition (Thick Film), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). All listed substitutes match these core specifications.

Q: Can RMCF0805FT4M99 be used as a direct replacement in non-automotive applications?

A: Yes. RMCF0805FT4M99 maintains all core electrical parameters (4.99 MOhms, ±1%, 0.125W, 0805 package) and operating temperature range identical to RC2012F4994CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in standard applications. The temperature coefficient specification (±200ppm/°C) differs from the original (±100ppm/°C); applications with tight tolerance requirements should evaluate this difference.

Q: What is the difference between the High Voltage feature in CHV0805-FX-4994ELF and standard moisture-resistant resistors?

A: The High Voltage feature indicates the CHV0805-FX-4994ELF is designed for circuits with elevated voltage stress conditions. All electrical parameters (resistance, tolerance, power rating, package) remain identical to RC2012F4994CS. Selection depends on circuit voltage requirements; standard applications do not require this feature.

Q: Are there physical compatibility concerns when substituting parts with different seated heights?

A: All substitute parts maintain the same 0805 (2012 Metric) package format and footprint dimensions (0.079" L x 0.049" W). Seated height variations (0.020" to 0.026") are within standard 0805 package tolerances and do not affect PCB assembly compatibility. Height differences may be relevant only for applications with strict vertical clearance constraints.

Q: Do all substitute parts have identical moisture sensitivity levels?

A: Yes. All substitute parts and the original RC2012F4994CS are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard dry storage conditions are not required.

Q: Which substitute offers the best inventory availability?

A: RMCF0805FT4M99 (Stackpole Electronics Inc) provides the highest inventory availability at 295,776 pcs, followed by RC0805FR-074M99L (YAGEO) at 52,025 pcs. Both support high-volume production requirements.
