Substitute Part Grouping Explanation

Substitute parts for the RC2012F3402CS are qualified based on strict electrical and mechanical parameter matching:

Core Substitution Criteria:

• Resistance value: 34 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these core criteria. Variations in physical dimensions (height-seated maximum) and compliance certifications (RoHS status, AEC-Q200 ratings) are secondary parameters that do not affect electrical interchangeability within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

RC0805FR-0734KL (YAGEO), CRCW080534K0FKEA (Vishay Dale), ERJ-6ENF3402V (Panasonic Electronic Components), and RMCF0805FT34K0 (Stackpole Electronics Inc) are all qualified substitutes with ROHS3 compliance status matching the original RC2012F3402CS specification.

Conditional Substitute:

CRCW080534K0FKTA (Vishay Dale) meets all electrical and mechanical parameters but carries RoHS Non-compliant status. This part is suitable only for applications where RoHS compliance is not a regulatory requirement.

Compliance Considerations:

All recommended primary substitutes maintain ROHS3 Compliant status and REACH Unaffected designation, ensuring regulatory alignment with the original component. Height-seated maximum variations (0.50mm to 0.70mm) remain within typical PCB assembly tolerances and do not affect circuit performance.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0734KL replace RC2012F3402CS in existing designs?

A: Yes. RC0805FR-0734KL meets all core electrical parameters (34 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and maintains identical 0805 package footprint. The 0.06mm reduction in maximum seated height (0.60mm vs 0.66mm) is within standard PCB assembly tolerances.

Q: What is the difference between CRCW080534K0FKEA and CRCW080534K0FKTA?

A: Both parts are electrically and mechanically identical (34 kΩ ±1%, 0.125W, 0805 package). The primary difference is RoHS compliance status: CRCW080534K0FKEA is ROHS3 Compliant, while CRCW080534K0FKTA is RoHS Non-compliant. Select CRCW080534K0FKEA for applications requiring RoHS certification.

Q: Are automotive-rated substitutes (AEC-Q200) compatible with non-automotive applications?

A: Yes. CRCW080534K0FKEA, CRCW080534K0FKTA, ERJ-6ENF3402V, and RMCF0805FT34K0 carry AEC-Q200 automotive qualification. These parts meet or exceed the electrical and reliability requirements of the original RC2012F3402CS and are fully compatible with non-automotive circuit designs.

Q: Does package height variation affect PCB assembly?

A: No. All substitute parts maintain 0805 (2012 Metric) package dimensions with height-seated maximum values ranging from 0.50mm to 0.70mm. These variations fall within standard reflow soldering and automated assembly process windows and do not require design modifications.

Q: Which substitute offers the highest inventory availability?

A: RC0805FR-0734KL (YAGEO) provides 46,272 pieces in stock, followed by RMCF0805FT34K0 (Stackpole Electronics Inc) with 39,027 pieces and ERJ-6ENF3402V (Panasonic Electronic Components) with 22,590 pieces.
