Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.7 kOhms
• Tolerance: ±1%
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistance: Required
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitutes may have equal or higher power ratings (0.333W or greater). Higher power ratings provide thermal margin without affecting electrical performance in applications designed for the original specification.

Identified Substitutes:

1. RC1210FR-072K7L (YAGEO): Upgrade substitute with 0.5W power rating. Maintains all mandatory parameters with enhanced thermal capacity.

2. CRCW12102K70FKEA (Vishay Dale): Similar substitute with 0.5W power rating and automotive AEC-Q200 qualification. Suitable for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

RC3225F272CS (Samsung Electro-Mechanics) remains the primary specification. Select this part for applications where the 1/3W power rating is sufficient and Samsung sourcing is preferred.

RC1210FR-072K7L (YAGEO) is the recommended upgrade substitute. The 0.5W power rating provides additional thermal margin while maintaining identical electrical characteristics and compliance certifications. This part is suitable for applications requiring higher reliability margins or where thermal stress may be a concern. YAGEO maintains active production status with substantial inventory availability (32,762 units).

CRCW12102K70FKEA (Vishay Dale) is the recommended substitute for automotive and mission-critical applications. The AEC-Q200 qualification provides automotive-grade reliability assurance. The 0.5W power rating and identical electrical specifications make this part suitable for automotive electronics, industrial control systems, and applications requiring enhanced quality documentation. Vishay maintains active production with 10,564 units in stock.

All three parts are ROHS3 compliant, MSL 1 rated, and operate across the identical temperature range. Selection should be based on application requirements, supply chain preferences, and any automotive or quality certifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-072K7L replace RC3225F272CS directly?

A: Yes. Both parts share identical resistance (2.7 kOhms), tolerance (±1%), package (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). The RC1210FR-072K7L has a higher power rating (0.5W vs. 0.333W), which provides thermal margin without affecting electrical performance.

Q: Can CRCW12102K70FKEA replace RC3225F272CS directly?

A: Yes. All electrical and environmental specifications are identical. The CRCW12102K70FKEA includes AEC-Q200 automotive qualification, making it suitable for automotive applications or where enhanced quality assurance is required.

Q: What is the difference between the three parts?

A: The primary differences are manufacturer, power rating, and certifications. RC3225F272CS (Samsung) is rated 1/3W. RC1210FR-072K7L (YAGEO) and CRCW12102K70FKEA (Vishay Dale) are both rated 1/2W. CRCW12102K70FKEA includes AEC-Q200 automotive qualification. All other electrical and environmental parameters are identical.

Q: Are there physical size differences?

A: All three parts use the 1210 (3225 Metric) package. Minor dimensional variations exist within standard tolerances: length ranges from 0.122" to 0.126", width from 0.098" to 0.102", and height from 0.024" to 0.026". These variations are within standard PCB design tolerances and do not affect footprint compatibility.

Q: Which part should I select for a new design?

A: For general applications, RC1210FR-072K7L (YAGEO) is recommended due to the higher power rating providing thermal margin and excellent inventory availability. For automotive or mission-critical applications, CRCW12102K70FKEA (Vishay Dale) is recommended due to AEC-Q200 qualification.

Q: Are all parts currently in production?

A: Yes. All three parts maintain active production status. RC3225F272CS has 1,022 units in stock, RC1210FR-072K7L has 32,762 units, and CRCW12102K70FKEA has 10,564 units available.

Q: Do packaging formats differ?

A: Yes. RC3225F272CS uses standard packaging. RC1210FR-072K7L is available in Cut Tape (CT) and Digi-Reel® formats. CRCW12102K70FKEA is supplied in Tape & Reel (TR) format. Confirm packaging compatibility with your assembly process requirements.
