Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F621CS are grouped based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Matching Parameters:

• Resistance value: 620 Ohms
• Tolerance: ±1%
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL 1 rating

Primary Group (Direct 1:1 Substitutes): Parts matching all critical parameters with identical 0.125W (1/8W) power rating. These include AC0805FR-07620RL (YAGEO), ERJ-6ENF6200V (Panasonic), RC0805FR-07620RL (YAGEO), and RMCF0805FT620R (Stackpole Electronics Inc).

Secondary Group (Higher Power Rating): Parts with identical electrical and mechanical specifications but elevated power rating of 0.5W (1/2W). These include CRCW0805620RFKEAHP (Vishay Dale) and RCS0805620RFKEA (Vishay Dale). These are suitable for applications requiring additional thermal margin.

Tertiary Group (Standard Automotive Grade): CRCW0805620RFKEA (Vishay Dale) matches all parameters with standard 0.125W rating and AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Non-Automotive Applications): RC0805FR-07620RL (YAGEO) provides equivalent performance with identical 0.125W power rating and matching dimensional profile. This part is available in Cut Tape (CT) & Digi-Reel® packaging format, suitable for lower-volume procurement requirements.

For Automotive-Grade Applications: CRCW0805620RFKEA (Vishay Dale) or RMCF0805FT620R (Stackpole Electronics Inc) are recommended substitutes. Both parts carry AEC-Q200 automotive qualification, RoHS3 compliance, and maintain identical electrical specifications. CRCW0805620RFKEA offers the lowest maximum seated height (0.50mm), while RMCF0805FT620R provides high inventory availability (320,220 pcs).

For Elevated Thermal Margin Applications: CRCW0805620RFKEAHP (Vishay Dale) or RCS0805620RFKEA (Vishay Dale) provide 0.5W (1/2W) power rating within the same 0805 package footprint. These parts are suitable for circuits requiring additional power dissipation capability while maintaining identical resistance and tolerance specifications.

For High-Volume Procurement: RMCF0805FT620R (Stackpole Electronics Inc) demonstrates the highest inventory level (320,220 pcs) with AEC-Q200 qualification and standard 0.125W rating, supporting extended supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can AC0805FR-07620RL replace RCS2012F621CS directly on the PCB?

A: Yes. AC0805FR-07620RL matches all critical electrical parameters (620Ω ±1%, 0.125W, ±100ppm/°C, -55~155°C operating range) and package format (0805). The maximum seated height of 0.60mm is within acceptable tolerance for standard PCB assembly processes. Both parts are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between the standard CRCW0805620RFKEA and the CRCW0805620RFKEAHP variant?

A: The primary difference is power rating. CRCW0805620RFKEA is rated at 0.125W (1/8W), while CRCW0805620RFKEAHP is rated at 0.5W (1/2W). Both maintain identical resistance (620Ω), tolerance (±1%), package (0805), and operating temperature range (-55~155°C). The higher power rating variant includes pulse withstanding capability. Selection depends on circuit power dissipation requirements.

Q: Are all substitute parts suitable for automotive applications?

A: Not all. AC0805FR-07620RL, ERJ-6ENF6200V, CRCW0805620RFKEA, CRCW0805620RFKEAHP, RCS0805620RFKEA, and RMCF0805FT620R carry AEC-Q200 automotive qualification. RC0805FR-07620RL and the original RCS2012F621CS do not have AEC-Q200 rating. For automotive applications, select only AEC-Q200 qualified parts.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical or mechanical compatibility. RC0805FR-07620RL is supplied in Cut Tape (CT) & Digi-Reel® format, while other substitutes use Tape & Reel (TR) format. Selection depends on procurement volume and assembly line requirements, not board-level performance.

Q: What is the significance of maximum seated height variation among substitute parts?

A: Maximum seated height ranges from 0.50mm (Vishay Dale CRCW series) to 0.70mm (Panasonic ERJ-6EN series). These variations remain within standard PCB assembly tolerances and do not affect electrical performance. Height differences are relevant only for applications with strict vertical clearance constraints or high-density packaging requirements.

Q: Can I use CRCW0805620RFKEAHP (0.5W) in place of RCS2012F621CS (0.125W) without circuit modification?

A: Yes. The 0.5W variant is electrically and mechanically compatible with the 0.125W original part. The higher power rating provides additional thermal margin and does not negatively impact circuit operation. This substitution is suitable when supply constraints affect the standard 0.125W variant.

Q: Are all substitute parts compliant with RoHS3 and REACH regulations?

A: Yes. All listed substitute parts carry RoHS3 compliance and REACH Unaffected status, matching the original RCS2012F621CS specifications. All parts are classified under ECCN EAR99 and HTSUS 8533.21.0030.
