RMCS1206FT82R5 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT82R5 is a 1206 chip resistor manufactured by Stackpole Electronics Inc., rated at 82.5 Ohms with ±1% tolerance and 0.25W power dissipation. This thick film resistor features anti-sulfur construction and operates across the -55°C to 155°C temperature range. The part is currently in active production status with 731 units in stock.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification or alternative moisture resistance features.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT82R5 is determined by strict equivalence across the following parameters:

• Resistance value: 82.5 Ohms
• Tolerance: ±1%
• Power rating: 0.25W
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1

All four substitute parts meet these core electrical and mechanical requirements. Variations exist only in secondary features such as moisture resistance technology, automotive certification, and physical dimensions within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

CR1206-FX-82R5ELF (Bourns Inc.) is suitable for applications requiring moisture-resistant thick film construction with active product status and full RoHS3 compliance. Current inventory of 974 units supports immediate procurement.

CRCW120682R5FKEA (Vishay Dale) is the preferred selection for automotive applications requiring AEC-Q200 certification. This part maintains active production status with the highest inventory availability at 18,554 units, ensuring supply continuity.

ERJ-8ENF82R5V (Panasonic Electronic Components) meets automotive AEC-Q200 requirements but carries a "Not For New Designs" status. This designation indicates the manufacturer is transitioning away from this product line. Selection should be limited to legacy design support or applications where existing qualification data is already established. Inventory of 26,862 units remains available.

RC1206FR-0782R5L (YAGEO) provides moisture-resistant thick film construction with active product status. The highest inventory level of 45,300 units ensures reliable supply availability for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts interchangeably with the RMCS1206FT82R5?

A: Yes, all four substitute parts are electrically and mechanically equivalent. They share identical resistance values, tolerance, power rating, package type, temperature coefficient, and operating temperature range. Selection should be based on feature requirements (automotive certification, moisture resistance) and product status considerations.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur construction protects against sulfur-containing environmental contaminants, while moisture-resistant construction provides protection against humidity and moisture ingress. Both are thick film technologies with equivalent electrical performance for this 82.5 Ohm 1206 resistor.

Q: Should I use ERJ-8ENF82R5V if it has the highest inventory?

A: The ERJ-8ENF82R5V carries a "Not For New Designs" status from Panasonic. While electrically equivalent and currently in stock, this designation indicates the manufacturer is discontinuing the product line. Use this part only for legacy design support or when existing qualification documentation is available. For new designs, select from CR1206-FX-82R5ELF, CRCW120682R5FKEA, or RC1206FR-0782R5L.

Q: Which substitute is best for automotive applications?

A: Both CRCW120682R5FKEA (Vishay Dale) and ERJ-8ENF82R5V (Panasonic) carry AEC-Q200 automotive certification. CRCW120682R5FKEA is recommended for new automotive designs due to its active product status and superior inventory availability.

Q: Are there dimensional differences between these parts?

A: All parts use the 1206 (3216 Metric) package. Minor variations exist in seated height and length/width dimensions within standard tolerances. The RMCS1206FT82R5 measures 0.122" L × 0.061" W with 0.026" max height. Substitute parts measure 0.126" L × 0.063" W with heights ranging from 0.024" to 0.030". These variations are within standard PCB design tolerances for 1206 components.

Q: Do all parts meet REACH and RoHS requirements?

A: Yes, all five parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.
