Substitute Part Grouping Explanation

Substitute parts for the RMCF2010FT1K33 are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 1.33 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Package: 2010 (5025 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)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable in applications requiring the RMCF2010FT1K33.

Parameter Comparison

Engineering Selection Recommendations

CRCW20101K33FKEF (Vishay Dale) is the primary substitute option. This part maintains active production status and carries identical electrical and mechanical specifications to the RMCF2010FT1K33. With 8200 units in stock, it provides superior supply chain availability. Both parts are ROHS3 compliant, AEC-Q200 qualified, and suitable for automotive applications requiring -55°C to 155°C operation.

ERJ-12SF1331U (Panasonic) is a secondary substitute option. While electrically and mechanically equivalent, this part carries a "Not For New Designs" status, indicating it is in mature or declining production phase. This part remains suitable for legacy system maintenance and repair applications where supply exists (5812 units in stock). New design implementations should prioritize CRCW20101K33FKEF or the primary RMCF2010FT1K33.

Frequently Asked Questions (FAQ)

Q: Can CRCW20101K33FKEF replace RMCF2010FT1K33 in existing designs?

A: Yes. Both parts share identical resistance (1.33 kOhms), tolerance (±1%), power rating (0.75W), package (2010), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 automotive qualification. No circuit redesign or validation is required for direct substitution.

Q: Why is ERJ-12SF1331U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase with declining manufacturer support. While electrically and mechanically equivalent and suitable for repair or legacy applications, new product designs should specify RMCF2010FT1K33 or CRCW20101K33FKEF to ensure long-term supply continuity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RMCF2010FT1K33, CRCW20101K33FKEF, and ERJ-12SF1331U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the 2010 package designation?

A: The 2010 package (5025 Metric) is the physical footprint standard for all listed parts. This ensures mechanical compatibility on PCBs designed for any of these part numbers. Dimensions are 0.197" L × 0.098" W (5.00mm × 2.50mm) with maximum seated height of 0.028" (0.70mm).

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and operate across the identical temperature range (-55°C to 155°C), making them suitable for direct substitution in automotive circuits without additional qualification testing.
