Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3402CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 34 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8533.21.0030

All identified substitute parts meet these core requirements. Variations in height (seated maximum), specific feature sets (automotive AEC-Q200 certification), and RoHS compliance status are secondary differentiators that do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are functionally equivalent to the RCS2012F3402CS based on electrical and mechanical parameters. Selection among substitutes should be based on the following compliance and certification criteria:

ROHS3 Compliant Options (Preferred for regulated applications):

• CRCW080534K0FKEA (Vishay Dale)
• ERJ-6ENF3402V (Panasonic Electronic Components)
• RC0805FR-0734KL (YAGEO)
• RMCF0805FT34K0 (Stackpole Electronics Inc)

REACH Unaffected Options (Preferred for international supply chain):

• CRCW080534K0FKEA (Vishay Dale)
• ERJ-6ENF3402V (Panasonic Electronic Components)
• RC0805FR-0734KL (YAGEO)
• RMCF0805FT34K0 (Stackpole Electronics Inc)

Automotive AEC-Q200 Certified Options (For automotive applications):

• CRCW080534K0FKEA (Vishay Dale)
• CRCW080534K0FKTA (Vishay Dale)
• ERJ-6ENF3402V (Panasonic Electronic Components)
• RMCF0805FT34K0 (Stackpole Electronics Inc)

The CRCW080534K0FKTA part carries RoHS non-compliance and REACH Affected status and should be avoided in applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CRCW080534K0FKEA directly replace RCS2012F3402CS in all applications?

A: Yes. Both parts share identical electrical specifications (34 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), identical package dimensions (0805 / 2012 Metric, 0.079" L x 0.049" W), and equivalent compliance status (ROHS3 Compliant, REACH Unaffected). The height difference (0.020" vs 0.026" seated maximum) is within typical PCB assembly tolerances and does not affect functionality.

Q: What is the difference between CRCW080534K0FKEA and CRCW080534K0FKTA?

A: Both are Vishay Dale CRCW series 34 kOhms ±1% 0.125W 0805 resistors with identical electrical and mechanical specifications. The primary difference is regulatory compliance: CRCW080534K0FKEA is ROHS3 Compliant and REACH Unaffected, while CRCW080534K0FKTA is RoHS non-compliant and REACH Affected. Selection depends on application regulatory requirements.

Q: Are automotive AEC-Q200 certified parts required for non-automotive applications?

A: No. Automotive AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive applications. Parts with AEC-Q200 certification (CRCW080534K0FKEA, CRCW080534K0FKTA, ERJ-6ENF3402V, RMCF0805FT34K0) are suitable for any application requiring 34 kOhms ±1% 0.125W 0805 resistors. Selection should be based on compliance requirements and supply chain availability.

Q: Does the height variation among substitute parts affect PCB assembly?

A: Height variations range from 0.020" (0.50mm) to 0.028" (0.70mm) seated maximum. These differences are within standard PCB assembly process tolerances for 0805 components and do not affect reflow soldering, component placement, or electrical performance. All parts are mechanically compatible with standard 0805 footprints.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF3402V (Panasonic Electronic Components) has 22,590 pieces in stock. RC0805FR-0734KL (YAGEO) has 46,272 pieces in stock, representing the highest available inventory among all substitute options.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts meet the core electrical and mechanical requirements for direct substitution. No circuit design changes are required. PCB footprints, trace routing, and component placement remain unchanged. Substitution is transparent to circuit operation.
