Key Parameters

Substitute Part Grouping Explanation

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

• Resistance Value: Must be 309 Ohms
• Package / Case: Must be 0603 (1608 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Moisture Sensitivity Level: Must be MSL 1 or equivalent
• RoHS Status: Must be ROHS3 Compliant

Substitute parts may vary in:

• Tolerance: Tighter tolerance (±0.5%, ±0.1%) represents an upgrade
• Power Rating: Higher power rating (0.167W) represents an upgrade
• Temperature Coefficient: Lower temperature coefficient represents improved stability
• Manufacturer: Different manufacturers with equivalent specifications
• Certifications: Additional automotive qualification (AEC-Q200) or anti-sulfur features

Frequently Asked Questions (FAQ)

Q: Can RT0603DRD07309RL replace RT0603FRE07309RL in any application?

A: Yes. Both components share identical resistance value (309 Ohms), package (0603), power rating (0.1W), composition (thin film), and operating temperature range (-55°C ~ 155°C). The substitute offers improved tolerance (±0.5% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for direct substitution with enhanced performance.

Q: What is the difference between the automotive-qualified parts and the standard parts?

A: ERA-3AEB3090V and RG1608P-3090-B-T5 carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. RG1608P-3090-B-T5 additionally features anti-sulfur protection. These certifications are relevant only if the application requires automotive-grade components.

Q: Can RP73PF1J309RBTDF be used where 0.1W power rating is specified?

A: Yes. RP73PF1J309RBTDF is rated at 0.167W (1/6W), which exceeds the 0.1W requirement. Higher power rating provides additional thermal margin and is electrically compatible. The 0603 package dimensions remain identical.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, matching the main part RT0603FRE07309RL. Moisture Sensitivity Level is MSL 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Q: Which substitute offers the best tolerance specification?

A: ERA-3AEB3090V, RG1608P-3090-B-T5, and RP73PF1J309RBTDF all offer ±0.1% tolerance, representing the tightest specification available among the substitute options. RT0603DRD07309RL offers ±0.5% tolerance as an intermediate upgrade.
