Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603CRE074K99L is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 4.99 kOhms (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Power rating: minimum 0.1W (1/10W)
• Composition: Thin Film
• Operating temperature range: minimum -55°C ~ 155°C coverage
• RoHS compliance: ROHS3 Compliant

Tolerance Consideration: The main part specifies ±0.25% tolerance. Substitute parts with equal or tighter tolerance (±0.1% or ±0.05%) are electrically compatible and represent upgrades in precision. Parts with looser tolerance are not suitable substitutes.

Temperature Coefficient: The main part specifies ±50ppm/°C. Substitute parts with equal or lower temperature coefficient values (±25ppm/°C or ±10ppm/°C) provide improved stability and are acceptable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Performance): RT0603BRE074K99L (YAGEO) provides equivalent functionality with improved tolerance (±0.1% vs ±0.25%) while maintaining identical power rating, operating temperature range, and packaging. This part is suitable for direct replacement in Tape & Reel format.

Precision Upgrades: RG1608N-4991-W-T1 (Susumu) offers the tightest tolerance specification (±0.05%) and lowest temperature coefficient (±10ppm/°C) among all listed substitutes. This part is suitable for applications requiring enhanced precision and stability. AEC-Q200 automotive qualification is included.

Automotive-Qualified Alternatives: ERA-3AEB4991V (Panasonic) and RG1608N-4991-B-T5 (Susumu) both carry AEC-Q200 automotive qualification. These parts are suitable for automotive and high-reliability applications requiring formal qualification documentation.

Higher Power Rating Option: 7-2176088-2 (TE Connectivity) provides 0.167W (1/6W) power rating, exceeding the 0.1W specification of the main part. This part is suitable for applications with higher thermal dissipation requirements. Operating temperature range is -55°C ~ 155°C. Note: Operating temperature upper limit for MCT06030D4991BP500 is -55°C ~ 125°C, which is below the main part specification.

Anti-Sulfur Feature: MCT06030D4991BP500 (Vishay) and RG1608N-4991-B-T5 (Susumu) include anti-sulfur coating. These parts are suitable for environments with sulfur contamination exposure.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRE074K99L replace RT0603CRE074K99L directly? A: Yes. Both parts share identical resistance (4.99 kOhms), power rating (0.1W), package (0603), and operating temperature range (-55°C ~ 155°C). RT0603BRE074K99L provides tighter tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±50ppm/°C vs ±50ppm/°C), making it a compatible upgrade.

Q: What is the difference between packaging types (Tape & Reel vs Cut Tape)? A: Tape & Reel (TR) packaging is supplied on continuous tape for automated assembly. Cut Tape (CT) & Digi-Reel® packaging is supplied in smaller quantities on cut tape segments. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.

Q: Are Susumu RG1608 series parts suitable for high-precision applications? A: Yes. RG1608N-4991-W-T1 offers ±0.05% tolerance and ±10ppm/°C temperature coefficient, providing superior precision compared to the main part (±0.25% tolerance, ±50ppm/°C). Both Susumu parts include AEC-Q200 automotive qualification and anti-sulfur coating.

Q: Can I use 7-2176088-2 (TE Connectivity) as a substitute? A: Yes, with consideration for power rating. 7-2176088-2 provides 0.167W (1/6W) power rating, which exceeds the 0.1W requirement. This part is suitable for applications requiring higher thermal dissipation. All other electrical parameters are compatible.

Q: Which substitute part has the lowest temperature coefficient? A: RG1608N-4991-B-T5 and RG1608N-4991-W-T1 (both Susumu) specify ±10ppm/°C temperature coefficient, the lowest among all listed parts. This provides superior frequency stability and temperature performance compared to the main part (±50ppm/°C).

Q: Is MCT06030D4991BP500 suitable for all temperature ranges specified for the main part? A: No. MCT06030D4991BP500 specifies operating temperature range of -55°C ~ 125°C, which does not cover the upper limit of the main part specification (-55°C ~ 155°C). This part is suitable only for applications operating within -55°C ~ 125°C range.

Q: What does AEC-Q200 qualification mean? A: AEC-Q200 is an automotive industry qualification standard for passive components. ERA-3AEB4991V (Panasonic) and both Susumu RG1608 parts carry this qualification, indicating suitability for automotive and high-reliability applications with formal qualification documentation.
