Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F270CS is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 27 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Mechanical Compatibility Requirements:

• Package type: 1210 (3225 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Regulatory & Environmental Requirements:

• RoHS3 compliance (mandatory)
• MSL Level 1 or equivalent (mandatory)
• REACH Unaffected status (mandatory)

The RC1210FR-0727RL from YAGEO qualifies as a substitute because it maintains all critical electrical parameters, identical package configuration, and exceeds the power rating specification (0.5W vs. 0.333W), providing enhanced thermal margin while preserving all regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

The RC1210FR-0727RL from YAGEO is a qualified substitute for the RC3225F270CS from Samsung Electro-Mechanics based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical resistance value (27 Ohms), tolerance (±1%), and temperature coefficient (±100ppm/°C). The operating temperature range is identical across both parts (-55°C ~ 155°C).

Mechanical Compatibility: Both components utilize the 1210 (3225 Metric) package with two terminations, ensuring direct footprint compatibility on PCB assemblies.

Regulatory Compliance: Both parts are ROHS3 compliant, REACH Unaffected, and carry MSL Level 1 rating, meeting all environmental and regulatory requirements for equivalent application.

Performance Enhancement: The RC1210FR-0727RL provides a higher power rating (0.5W vs. 0.333W), which increases thermal margin and reliability in the application without introducing any electrical or mechanical incompatibility.

Product Status: Both components maintain Active product status, ensuring continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0727RL be used as a direct replacement for RC3225F270CS in existing designs?

A: Yes. Both components share identical electrical specifications (27 Ohms ±1%, ±100ppm/°C), identical package configuration (1210 / 3225 Metric), and equivalent regulatory certifications. Direct PCB footprint compatibility is maintained.

Q: What is the significance of the higher power rating on the YAGEO substitute?

A: The RC1210FR-0727RL is rated at 0.5W compared to the original 0.333W specification. This higher power rating provides additional thermal margin and does not create any incompatibility. The component will operate safely in applications designed for the lower power rating.

Q: Are there packaging differences between these two parts?

A: The RC3225F270CS is supplied in standard packaging, while the RC1210FR-0727RL is supplied in Tape & Reel (TR) format. Both maintain identical component dimensions and electrical characteristics. Tape & Reel packaging is standard for automated assembly processes.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) rating. They meet identical regulatory requirements for industrial and commercial applications.

Q: What parameters must remain identical for substitution to be valid?

A: Resistance value, tolerance, temperature coefficient, package type, number of terminations, and composition must all match exactly. The RC1210FR-0727RL meets all these criteria. Power rating may exceed the original specification without creating incompatibility.
