Engineering Selection Recommendations

RG2012P-4871-B-T5 (Susumu): Direct upgrade from the main part with improved tolerance (±0.1%), higher power rating (0.125W), extended operating temperature to 155°C, and automotive AEC-Q200 certification with anti-sulfur properties. Maintains identical manufacturer and series lineage. Suitable for applications requiring enhanced reliability and automotive-grade specifications.

7-2176092-7 (TE Connectivity Passive Product): Offers highest power dissipation capability (0.25W) with improved tolerance (±0.1%) and extended operating temperature range (-55°C ~ 155°C). Increased seated height (0.026") requires verification of PCB layout clearance. Appropriate for applications with higher thermal stress or power dissipation requirements.

RN73C2A4K87BTDF (TE Connectivity Passive Product): Provides superior temperature coefficient (±10ppm/°C) compared to main part (±25ppm/°C) with improved tolerance (±0.1%) and extended operating temperature range. Maintains equivalent power rating (0.1W). Increased seated height (0.026") requires PCB clearance verification. Suitable for precision applications with stringent temperature stability requirements.

ERA-6AEB4871V (Panasonic Electronic Components): Automotive AEC-Q200 certified with improved tolerance (±0.1%), higher power rating (0.125W), and extended operating temperature range (-55°C ~ 155°C). Moderate seated height (0.024") provides balanced form factor. Appropriate for automotive and high-reliability applications.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package dimensions (0.079" L x 0.049" W). Selection should be based on specific application requirements regarding tolerance precision, power dissipation, temperature stability, and environmental certifications.

Frequently Asked Questions (FAQ)

Q: Can RR1220P-4871-D-M be directly replaced with any of the listed substitutes?

A: All listed substitute parts share identical resistance value (4.87 kOhms), package format (0805 / 2012 Metric), and physical dimensions (0.079" L x 0.049" W). Direct replacement is mechanically and electrically feasible. However, seated height variations (0.020" to 0.026") require PCB layout verification to ensure clearance compatibility.

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

A: The main part RR1220P-4871-D-M features ±0.5% tolerance and 0.1W power rating with -55°C ~ 125°C operating range. All substitute parts offer improved tolerance (±0.1%), higher or equivalent power ratings (0.1W to 0.25W), and extended operating temperature range to 155°C. Some substitutes include automotive AEC-Q200 certification or enhanced temperature coefficient specifications.

Q: Which substitute part offers the best temperature stability?

A: RN73C2A4K87BTDF provides the lowest temperature coefficient at ±10ppm/°C compared to ±25ppm/°C for all other parts. This specification is critical for precision analog circuits requiring minimal resistance drift across temperature variations.

Q: Are automotive-grade substitutes available?

A: Yes. RG2012P-4871-B-T5 (Susumu) and ERA-6AEB4871V (Panasonic) both carry AEC-Q200 automotive certification. These parts are suitable for automotive applications and high-reliability environments requiring automotive-grade component qualification.

Q: What is the maximum power dissipation among substitute parts?

A: 7-2176092-7 (TE Connectivity) offers the highest power rating at 0.25W (1/4W), compared to 0.1W for the main part. This part is appropriate for applications with elevated thermal stress or higher current flow through the resistor.

Q: Do all substitute parts maintain the same moisture sensitivity level?

A: Yes. All parts, including the main part RR1220P-4871-D-M, are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is PCB layout modification required when substituting parts with different seated heights?

A: Parts with seated height of 0.026" (7-2176092-7 and RN73C2A4K87BTDF) are 0.006" taller than the main part (0.020"). PCB layout clearance must be verified to ensure no interference with adjacent components or solder mask patterns. Parts with 0.024" seated height (ERA-6AEB4871V and RT0805BRD074K87L) present minimal clearance concerns.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, consistent with the main part RR1220P-4871-D-M.

Q: Which substitute part is recommended for general-purpose applications without specific automotive or precision requirements?

A: RT0805BRD074K87L (YAGEO) provides balanced specifications with improved tolerance (±0.1%), higher power rating (0.125W), extended operating temperature range (-55°C ~ 155°C), and moderate seated height (0.024") without automotive certification overhead.
