Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F3401CS are qualified based on the following criteria:

Primary Matching Parameters:

• Resistance value: 3.4 kOhms
• Tolerance: ±1%
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Secondary Consideration:

• Power rating may vary (0.125W or 0.5W) depending on application requirements

All identified substitutes maintain identical electrical performance and mechanical compatibility within the specified parameter set. Substitutes are grouped by power rating classification to facilitate selection based on circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (0.125W Power Rating): CRCW08053K40FKEA, ERJ-6ENF3401V, and RC0805FR-073K4L are direct electrical and mechanical equivalents to the RCS2012F3401CS. All three maintain identical power rating, resistance value, tolerance, and operating temperature specifications. Selection among these options may be based on packaging preference (Tape & Reel versus Cut Tape) and supplier availability. CRCW08053K40FKEA and ERJ-6ENF3401V carry AEC-Q200 automotive qualification, while RC0805FR-073K4L provides moisture-resistant characteristics. All are ROHS3 compliant with MSL 1 rating.

Higher Power Rating Alternative (0.5W): CRCW08053K40FKEAHP provides increased power dissipation capability (0.5W versus 0.125W) while maintaining all other electrical parameters. This substitute is suitable for applications requiring enhanced thermal performance or pulse withstanding capability. The component carries AEC-Q200 automotive qualification and is ROHS3 compliant. Physical dimensions remain compatible with 0805 package footprints.

All substitute parts maintain Active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can CRCW08053K40FKEAHP (0.5W) be used as a direct replacement for RCS2012F3401CS (0.125W)?

A: Yes, CRCW08053K40FKEAHP is electrically and mechanically compatible. The higher power rating (0.5W) provides additional thermal margin and does not negatively impact circuit performance. The 0805 package dimensions remain identical. Selection depends on circuit design requirements and thermal considerations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes—CRCW08053K40FKEA, CRCW08053K40FKEAHP, ERJ-6ENF3401V, and RC0805FR-073K4L—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel® packaging (ERJ-6ENF3401V) provides smaller quantities on cut tape segments. Both formats are compatible with standard SMD assembly processes; selection depends on production volume and assembly equipment capability.

Q: Do the substitute parts have automotive qualification?

A: CRCW08053K40FKEA, CRCW08053K40FKEAHP, and ERJ-6ENF3401V carry AEC-Q200 automotive qualification. RC0805FR-073K4L does not list AEC-Q200 rating. Selection should reflect application requirements for automotive-grade components.

Q: Are physical dimensions identical across all substitutes?

A: All parts conform to 0805 (2012 Metric) package specification with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height varies slightly: RCS2012F3401CS (0.026" / 0.66mm), CRCW08053K40FKEA and CRCW08053K40FKEAHP (0.020" / 0.50mm), ERJ-6ENF3401V (0.028" / 0.70mm), and RC0805FR-073K4L (0.024" / 0.60mm). These variations remain within standard 0805 package tolerance and do not affect PCB footprint compatibility.
