Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07523RL is determined by the following criteria:

Mandatory Parameters (Must Match):

• Resistance value: 523 Ohms
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance

Allowable Variations:

• Tolerance: May be equal to or better (lower) than ±1%
• Power rating: May be equal to or greater than 0.125W
• Temperature coefficient: May be equal to or better (lower) than ±50ppm/°C
• Additional certifications (AEC-Q200, anti-sulfur features) are permissible enhancements

Three substitute parts meet these criteria and are grouped by their performance characteristics relative to the main part.

Parameter Comparison

Engineering Selection Recommendations

9-2176091-1 (TE Connectivity Passive Product): This substitute offers improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W) while maintaining identical package and operating temperature specifications. Selection is appropriate for applications requiring enhanced precision and thermal margin. No automotive certification is provided.

ERA-6AEB5230V (Panasonic Electronic Components): This substitute provides improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) with AEC-Q200 automotive qualification. Power rating and physical dimensions remain equivalent to the main part. Selection is appropriate for automotive applications or designs requiring automotive-grade reliability standards.

RG2012P-5230-B-T5 (Susumu): This substitute combines improved tolerance (±0.1%), lower temperature coefficient (±25ppm/°C), AEC-Q200 automotive certification, and anti-sulfur features. Physical dimensions are equivalent. Selection is appropriate for automotive applications in corrosive environments or designs requiring the highest reliability standards among available substitutes.

All substitute parts maintain full compatibility with the original part's package footprint, thermal characteristics, and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can 9-2176091-1 be used as a direct replacement for RT0805FRE07523RL? A: Yes. Both parts share identical resistance value, package type, operating temperature range, and RoHS compliance. The substitute offers superior tolerance and higher power rating, making it functionally compatible for all applications where the original part is specified.

Q: What is the primary advantage of ERA-6AEB5230V over the original part? A: ERA-6AEB5230V provides AEC-Q200 automotive qualification, improved tolerance (±0.1%), and lower temperature coefficient (±25ppm/°C). These characteristics make it suitable for automotive applications or designs requiring automotive-grade component reliability.

Q: Why does RG2012P-5230-B-T5 include anti-sulfur features? A: Anti-sulfur features protect the resistor from sulfur-containing environmental contaminants that can degrade thin film resistors in certain industrial or automotive applications. This enhancement is relevant for designs exposed to corrosive atmospheres.

Q: Are all substitute parts available in the same packaging format? A: Yes. All parts are supplied in Tape & Reel (TR) packaging in 0805 (2012 Metric) format, ensuring compatibility with standard surface mount assembly processes.

Q: Can substitute parts with ±0.1% tolerance be used in circuits designed for ±1% tolerance? A: Yes. Parts with tighter tolerance specifications are functionally compatible with designs specified for looser tolerances. The substitute will perform within the original specification range.

Q: What is the significance of the temperature coefficient difference between the main part and substitutes? A: The main part has ±50ppm/°C temperature coefficient, while substitutes have ±25ppm/°C. Lower temperature coefficient indicates better resistance stability across temperature variations, beneficial for precision analog circuits or wide temperature range applications.

Q: Are there any physical dimension differences that affect PCB layout? A: All parts use identical 0805 (2012 Metric) package dimensions (0.079" L x 0.049" W). Height variations are minimal (0.020" to 0.026" seated height) and do not affect standard PCB design or assembly processes.
