Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F30R1CS is determined by the following mandatory parameters:

Electrical Compatibility Requirements:

• Resistance value: 30.1 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility Requirements:

• Package / Case: 2010 (5025 Metric) (exact match required)
• Number of Terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Allowable Variations:

• Power Rating: Substitute parts may have equal or higher power rating (0.75W acceptable as upgrade from 0.667W)
• Features: Substitute parts may include additional certifications (AEC-Q200) without affecting base functionality
• Packaging Format: Tape & Reel (TR) acceptable as alternative to standard packaging

All three identified substitute parts meet these criteria with matching electrical and mechanical specifications while offering enhanced power ratings and automotive-grade certifications.

Parameter Comparison

Engineering Selection Recommendations

CRCW201030R1FKEF (Vishay Dale): Active product status with automotive AEC-Q200 certification. Power rating of 0.75W exceeds the 0.667W requirement. Suitable for applications requiring automotive-grade reliability and extended power margin. ROHS3 compliant with unlimited moisture sensitivity rating.

ERJ-12SF30R1U (Panasonic Electronic Components): Marked as "Not For New Designs" product status. While electrically and mechanically compatible with automotive AEC-Q200 certification, this part should not be selected for new circuit designs. Existing designs currently using this component may continue operation with this part.

RMCF2010FT30R1 (Stackpole Electronics Inc): Active product status with automotive AEC-Q200 certification. Power rating of 0.75W provides margin above the 0.667W specification. Recommended for new designs requiring automotive-grade performance and enhanced power handling capability. ROHS3 compliant with unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can CRCW201030R1FKEF, ERJ-12SF30R1U, or RMCF2010FT30R1 be used as direct replacements for RC5025F30R1CS?

A: Yes, all three substitute parts are electrically and mechanically compatible. They share identical resistance (30.1 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), package format (2010/5025 Metric), and termination count (2). The substitute parts feature higher power ratings (0.75W vs. 0.667W), which represents an upgrade in power handling capability.

Q: What is the difference in height between the main part and substitute parts?

A: The RC5025F30R1CS has a maximum seated height of 0.026" (0.66mm), while all three substitute parts have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB layout tolerances for 2010 package components and does not affect functional compatibility.

Q: Why do the substitute parts have higher power ratings?

A: The substitute parts (CRCW201030R1FKEF, ERJ-12SF30R1U, RMCF2010FT30R1) are rated at 0.75W (3/4W) compared to the main part's 0.667W (2/3W). This represents a design enhancement by the respective manufacturers and does not affect compatibility. Higher power rating provides additional thermal margin in the application.

Q: What does "Not For New Designs" mean for ERJ-12SF30R1U?

A: This product status indicates that Panasonic Electronic Components has discontinued this part for new design applications. While the part remains electrically and mechanically compatible and is suitable for replacement in existing designs, it should not be selected for new circuit development. Use CRCW201030R1FKEF or RMCF2010FT30R1 for new designs.

Q: Are all substitute parts automotive-grade?

A: Yes, all three substitute parts carry AEC-Q200 automotive certification, which is an additional qualification beyond the moisture-resistant feature of the main part. This certification indicates suitability for automotive applications with enhanced reliability requirements.

Q: What is the significance of the 0.002" height difference in PCB assembly?

A: The height difference between the main part (0.66mm) and substitute parts (0.70mm) is negligible for standard PCB assembly processes. Both dimensions fall within the acceptable range for 2010 package components and do not require PCB layout modifications.

Q: Can I mix RC5025F30R1CS and substitute parts in the same circuit?

A: Yes. All parts share identical electrical specifications (resistance, tolerance, temperature coefficient, operating temperature range) and mechanical compatibility (package, termination count, dimensions). Mixing parts from different manufacturers in the same circuit does not create functional or reliability issues.
