Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3225J623CS is determined by the following critical parameters:

Resistance Value: The substitute part must maintain 62 kOhms nominal resistance to ensure circuit function.

Package Compatibility: The 1210 (3225 Metric) package dimension is mandatory for PCB layout compatibility. Substitute parts must fit within the specified footprint: 0.126" L x 0.100" W (3.20mm x 2.55mm) with height not exceeding 0.026" (0.66mm).

Electrical Specifications: Operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C) must be maintained or exceeded.

Compliance Requirements: RoHS3 compliance and MSL 1 rating are required for equivalent substitution.

Performance Enhancement: Substitute parts may offer improved tolerance (tighter than ±5%) or increased power rating (greater than 0.333W) while maintaining all other specifications.

The RC1210FR-0762KL from YAGEO qualifies as a substitute based on identical resistance value, compatible package dimensions, matching temperature range, equivalent composition, and full compliance certification.

Parameter Comparison

Engineering Selection Recommendations

RC3225J623CS (Samsung Electro-Mechanics): Select this part when the original design specification requires ±5% tolerance and 0.333W power rating. This component is active in production with established supply availability (815 pieces in stock). Full ROHS3 and MSL 1 compliance supports applications requiring regulatory certification.

RC1210FR-0762KL (YAGEO): Select this substitute when improved tolerance performance (±1% versus ±5%) or increased power dissipation capability (0.5W versus 0.333W) benefits circuit performance. The YAGEO part maintains identical resistance value, package footprint compatibility, and full compliance certifications. Dimensions are within acceptable tolerance for 1210 package specifications. Higher inventory availability (5731 pieces) supports extended production runs.

Both parts are active products with current manufacturing status and equivalent regulatory compliance. Selection between them depends on tolerance and power rating requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0762KL directly replace RC3225J623CS on existing PCBs?

A: Yes. Both components use the 1210 (3225 Metric) package with compatible footprint dimensions. The YAGEO part dimensions (0.122" L x 0.102" W, height 0.024") are within the tolerance band of the Samsung part (0.126" L x 0.100" W, height 0.026"). PCB layout compatibility is maintained.

Q: What is the tolerance difference between these parts?

A: RC3225J623CS has ±5% tolerance, while RC1210FR-0762KL has ±1% tolerance. The YAGEO substitute provides tighter tolerance performance. Both maintain the same 62 kOhms nominal resistance value.

Q: Does the increased power rating of RC1210FR-0762KL affect circuit operation?

A: No. The RC1210FR-0762KL is rated for 0.5W (1/2W) compared to the RC3225J623CS at 0.333W (1/3W). Higher power rating does not degrade performance in circuits designed for lower power dissipation. This provides additional thermal margin in the application.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC3225J623CS and RC1210FR-0762KL are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, supporting applications requiring regulatory certification.

Q: What is the temperature coefficient specification for both parts?

A: Both components have identical temperature coefficient of ±100ppm/°C and operate across -55°C to 155°C. Temperature stability performance is equivalent.

Q: Which part should be selected for new designs?

A: For new designs, RC1210FR-0762KL is suitable when tolerance and power rating specifications align with circuit requirements. For designs requiring exact specification match to RC3225J623CS, the Samsung part remains the primary selection.
