Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603J102CS is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 1 kOhms
• Power rating: 0.05W (1/20W)
• Package / Case: 0201 (0603 Metric)
• Composition: Thick Film
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Number of terminations: 2
• RoHS3 compliance status
• MSL Level 1 rating

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter than ±5%
• Temperature coefficient: May be equal to or lower than ±250ppm/°C
• Operating temperature range: May be equal to or wider than -55°C ~ 125°C
• Packaging format: Cut Tape (CT), Tape & Reel (TR), or Digi-Reel® formats are interchangeable

The identified substitute parts meet all mandatory matching criteria while offering improved tolerance and temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three components maintain Active product status with full RoHS3 compliance and REACH Unaffected classification, ensuring regulatory compliance across all substitution options.

CRCW02011K00FKED (Vishay Dale): This substitute provides ±1% tolerance with ±100ppm/°C temperature coefficient and extends the operating temperature range to -55°C ~ 155°C. It is available in Cut Tape (CT) and Digi-Reel® packaging formats with significantly higher inventory availability (200,828 pcs).

ERJ-1RHD1001C (Panasonic Electronic Components): This substitute offers the tightest tolerance specification at ±0.5% with the lowest temperature coefficient at ±50ppm/°C. Operating temperature range matches the original specification at -55°C ~ 125°C. Packaging is supplied in Tape & Reel (TR) format with 1,823 pcs in stock.

Component selection depends on application requirements for tolerance precision, temperature stability, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW02011K00FKED replace RC0603J102CS in all applications?

A: CRCW02011K00FKED meets all mandatory electrical and mechanical parameters for direct substitution. The ±1% tolerance is tighter than the original ±5%, and the extended operating temperature range to 155°C provides additional thermal margin. Packaging format differences (Cut Tape/Digi-Reel vs. original Cut Tape) do not affect electrical compatibility.

Q: What is the primary difference between the two substitute parts?

A: ERJ-1RHD1001C provides superior tolerance (±0.5%) and temperature coefficient (±50ppm/°C) compared to CRCW02011K00FKED (±1% tolerance, ±100ppm/°C). CRCW02011K00FKED offers a wider operating temperature range extending to 155°C. Both are electrically and mechanically compatible with RC0603J102CS.

Q: Are there packaging compatibility concerns when substituting these parts?

A: All three components use identical 0201 (0603 Metric) package dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) with 0.010" (0.26mm) maximum seated height. Packaging format differences (Cut Tape, Tape & Reel, Digi-Reel) relate to supply and handling only and do not affect PCB assembly compatibility.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. RC0603J102CS, CRCW02011K00FKED, and ERJ-1RHD1001C are all ROHS3 Compliant with REACH Unaffected status, ensuring regulatory compliance across all substitution options.

Q: Which substitute should be selected for high-precision applications?

A: ERJ-1RHD1001C is specified for applications requiring high precision, offering ±0.5% tolerance and ±50ppm/°C temperature coefficient. This component provides the most stable resistance value across temperature variations.

Q: Is moisture sensitivity a factor in selecting substitutes?

A: All three components carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Storage and handling requirements are identical across all options.
