Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025J472CS is based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 4.7 kOhms (exact match required)
• Package / Case: 2010 (5025 Metric) footprint (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (must meet or exceed)
• RoHS3 compliance (must maintain)
• MSL 1 rating (must maintain or improve)

Allowable Upgrade Parameters:

• Tolerance: ±5% can be upgraded to ±1% for improved precision
• Power rating: 0.667W can be upgraded to 0.75W for increased thermal margin
• Temperature coefficient: ±100ppm/°C can be matched or improved (lower values acceptable)
• Certifications: Automotive AEC-Q200 qualification is an optional enhancement

Substitution Categories:

Upgrade substitutes provide enhanced specifications (higher power rating and/or tighter tolerance) while maintaining all mandatory parameters.

Similar substitutes meet all mandatory parameters with optional automotive certification but may have minor variations in non-critical specifications such as seated height or temperature coefficient.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (Non-Automotive):

RC2010JK-074K7L (YAGEO) is the primary upgrade substitute. It provides a 0.083W power rating increase (0.75W vs. 0.667W) while maintaining ±5% tolerance and all mandatory electrical parameters. This part is Active status and suitable for new designs.

RC2010FK-074K7L (YAGEO) is recommended when tolerance improvement to ±1% is required without automotive certification. This part offers both enhanced power rating and precision tolerance.

For Automotive Applications:

AC2010JK-074K7L (YAGEO) combines automotive AEC-Q200 qualification with ±5% tolerance and 0.75W power rating. This part is Active status and suitable for automotive-grade circuit designs.

CRCW20104K70FKEF (Vishay Dale) provides automotive AEC-Q200 qualification with ±1% tolerance and 0.75W power rating. This part is Active status and suitable for precision automotive applications.

For Legacy or Constrained Designs:

ERJ-12ZYJ472U (Panasonic Electronic Components) meets all mandatory parameters with automotive AEC-Q200 qualification. However, this part carries "Not For New Designs" status and should only be selected when design constraints or supply chain requirements necessitate its use. The temperature coefficient is ±200ppm/°C, which is less precise than the main part.

Selection Priority:

1. Verify power dissipation requirements; if actual dissipation exceeds 0.667W, upgrade to 0.75W rated parts
2. Confirm automotive certification requirements; if required, select AEC-Q200 qualified parts
3. Assess tolerance requirements; if ±1% precision is needed, select RC2010FK-074K7L or CRCW20104K70FKEF
4. Avoid ERJ-12ZYJ472U for new designs due to "Not For New Designs" status

Frequently Asked Questions (FAQ)

Q: Can RC5025J472CS be directly replaced with any of the listed substitutes?

A: Yes, all listed substitutes are electrically and mechanically compatible. They share the same 4.7 kOhms resistance, 2010 (5025 Metric) package footprint, thick film composition, and operating temperature range. Substitution is a direct PCB replacement without circuit modification.

Q: What is the difference between "Upgrade" and "Similar" substitute categories?

A: Upgrade substitutes (AC2010JK-074K7L, RC2010FK-074K7L, RC2010JK-074K7L) provide enhanced specifications such as higher power rating (0.75W vs. 0.667W) or tighter tolerance (±1% vs. ±5%). Similar substitutes (CRCW20104K70FKEF, ERJ-12ZYJ472U) meet all mandatory parameters but may have optional certifications or minor specification variations.

Q: Why would I select a substitute with higher power rating if my circuit only requires 0.667W?

A: Higher power ratings provide thermal margin and improved reliability under worst-case operating conditions, including component aging and temperature extremes. A 0.75W rated part operating at 0.667W dissipation experiences lower junction temperature and extended service life.

Q: Are all substitutes suitable for new product designs?

A: No. ERJ-12ZYJ472U carries "Not For New Designs" status and should only be used in legacy designs or when supply constraints require it. All other substitutes (AC2010JK-074K7L, RC2010FK-074K7L, RC2010JK-074K7L, CRCW20104K70FKEF) are Active status and suitable for new designs.

Q: What is the significance of AEC-Q200 certification?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this certification (AC2010JK-074K7L, CRCW20104K70FKEF, ERJ-12ZYJ472U) have undergone additional reliability testing and are approved for automotive applications. Non-automotive parts (RC2010FK-074K7L, RC2010JK-074K7L) are suitable for industrial and consumer applications.

Q: Can I use a ±1% tolerance part in place of a ±5% tolerance part?

A: Yes. Tolerance is a unidirectional upgrade parameter. A ±1% part (RC2010FK-074K7L, CRCW20104K70FKEF) provides tighter resistance accuracy than a ±5% part and is fully compatible. The reverse substitution (±5% for ±1%) is not permitted.

Q: What does MSL 1 (Unlimited) rating mean?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts maintain MSL 1 rating, ensuring consistent moisture resistance and reliability.

Q: Are there physical size differences between the main part and substitutes?

A: All parts share the same 2010 (5025 Metric) package with dimensions 0.197" L x 0.098" W (5.00mm x 2.50mm). Seated height varies slightly (0.026" to 0.028"), but this variation is within standard PCB assembly tolerances and does not affect compatibility.

Q: Which substitute offers the best overall performance?

A: RC2010FK-074K7L provides the optimal balance of specifications: ±1% tolerance for precision, 0.75W power rating for thermal margin, Active product status for long-term availability, and ROHS3 compliance. For automotive applications, CRCW20104K70FKEF offers equivalent performance with AEC-Q200 certification.
