Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225J682CS are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 6.8 kOhms (exact match required)
• Package format: 1210 (3225 Metric) (physical and electrical compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±100ppm/°C (thermal stability match)
• Operating Temperature Range: -55°C ~ 155°C (thermal envelope match)
• Moisture Resistant: Yes (environmental protection consistency)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (moisture sensitivity compatibility)

Allowable Variations:

• Tolerance: May be equal or tighter (±5% or ±1%)
• Power Rating: May be equal or higher (0.333W or 0.5W)
• Manufacturer: Different manufacturers permitted
• Packaging Format: Tape & Reel acceptable as alternative to standard packaging

The two identified substitutes (RC1210FR-076K8L and RC1210JR-076K8L) both meet all mandatory compatibility parameters while offering enhanced power ratings (0.5W versus 0.333W) and, in one case, improved tolerance specification (±1% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts RC1210FR-076K8L and RC1210JR-076K8L are qualified alternatives to the RC3225J682CS based on electrical and mechanical compatibility within the 1210 package format.

RC1210FR-076K8L Selection Criteria: This YAGEO component provides a tighter tolerance specification (±1% versus ±5%) while maintaining identical resistance value and thermal characteristics. The increased power rating (0.5W versus 0.333W) provides additional thermal margin in applications. This part is suitable for designs requiring improved accuracy or higher power dissipation capability. RoHS3 compliance and MSL 1 rating ensure regulatory and environmental compatibility. Current inventory of 7382 pieces supports production requirements.

RC1210JR-076K8L Selection Criteria: This YAGEO component maintains the ±5% tolerance specification of the original part while providing increased power rating (0.5W versus 0.333W). The component is electrically and mechanically interchangeable with the RC3225J682CS. RoHS3 compliance and MSL 1 rating ensure regulatory and environmental compatibility. Current inventory of 10154 pieces provides the highest availability among all options.

Both substitutes are Active status products from an established manufacturer, ensuring long-term supply continuity and technical support.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-076K8L and RC1210JR-076K8L be used interchangeably with RC3225J682CS?

A: Both parts are mechanically and electrically compatible substitutes. The 1210 package format is identical across all three components. Resistance value (6.8 kOhms), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) are matched. The primary differences are tolerance specification and power rating, both of which represent equal or improved performance characteristics.

Q: What is the difference between RC1210FR-076K8L and RC1210JR-076K8L?

A: The RC1210FR-076K8L offers ±1% tolerance compared to the ±5% tolerance of RC1210JR-076K8L. Both components share identical 6.8 kOhms resistance, 0.5W power rating, and thermal specifications. Selection between these two depends on circuit accuracy requirements. The RC1210JR-076K8L maintains tolerance parity with the original RC3225J682CS.

Q: Are the physical dimensions compatible across all three parts?

A: All three components use the 1210 (3225 Metric) package format. The RC3225J682CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with maximum seated height of 0.026" (0.66mm). The YAGEO substitutes measure 0.122" L x 0.102" W (3.10mm x 2.60mm) with maximum seated height of 0.024" (0.60mm). These minor dimensional variations remain within the 1210 package specification and do not affect PCB layout compatibility or mounting procedures.

Q: Do all parts meet the same regulatory and compliance standards?

A: Yes. The RC3225J682CS and both substitute parts (RC1210FR-076K8L and RC1210JR-076K8L) are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. All components are classified under ECCN EAR99 and HTSUS 8533.21.0030. Regulatory and environmental compliance is equivalent across all three options.

Q: What is the power dissipation difference between the main part and substitutes?

A: The RC3225J682CS is rated for 0.333W (1/3W) power dissipation. Both substitute parts (RC1210FR-076K8L and RC1210JR-076K8L) are rated for 0.5W (1/2W) power dissipation. The increased power rating in substitute parts provides additional thermal margin and allows operation in higher power applications without exceeding component limits.

Q: Which substitute part should be selected for maximum inventory availability?

A: The RC1210JR-076K8L offers the highest current inventory with 10154 pieces in stock, compared to 7382 pieces for RC1210FR-076K8L and 948 pieces for the original RC3225J682CS. If supply continuity is the primary concern, RC1210JR-076K8L provides the best availability position.
