Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following criteria:

Primary Electrical Criteria (Must Match):

• Resistance value: 3 kOhms
• Tolerance: ±1%
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Primary Mechanical Criteria (Must Match):

• Package / Case: 1210 (3225 Metric)
• Number of Terminations: 2

Allowable Variations:

• Power Rating: Substitute parts may have equal or higher power rating (0.5W / 1/2W acceptable as upgrade from 0.333W / 1/3W)
• Manufacturer certifications: Additional certifications (AEC-Q200) are permissible
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) acceptable

Identified Substitute Parts:

Upgrade Category (Higher Power Rating):

• RC1210FR-073KL (YAGEO) — 0.5W rating
• AC1210FR-073KL (YAGEO) — 0.5W rating with AEC-Q200
• CRCW12103K00FKEA (Vishay Dale) — 0.5W rating with AEC-Q200

All substitute parts maintain identical electrical performance at the specified 3 kOhms ±1% with matching temperature characteristics and operating range.

Parameter Comparison

Engineering Selection Recommendations

RC1210FR-073KL (YAGEO) — Recommended for general-purpose substitution. Maintains identical electrical specifications with increased power rating (0.5W). Active product status with ROHS3 compliance and MSL 1. Suitable for applications where the original 0.333W rating is adequate and no automotive qualification is required.

AC1210FR-073KL (YAGEO) — Recommended for automotive and high-reliability applications. Includes AEC-Q200 certification in addition to increased power rating (0.5W). Active product status with ROHS3 compliance and MSL 1. Select this part when automotive-grade components are specified or when enhanced reliability documentation is required.

CRCW12103K00FKEA (Vishay Dale) — Recommended for automotive and high-reliability applications. Includes AEC-Q200 certification with increased power rating (0.5W). Active product status with ROHS3 compliance and MSL 1. Suitable for applications requiring automotive qualification and Vishay Dale supply chain integration.

All three substitute parts are electrically and mechanically compatible with RC3225F302CS. Selection should be based on supply chain preference, automotive qualification requirements, and packaging format availability (Tape & Reel or Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-073KL replace RC3225F302CS directly?

A: Yes. RC1210FR-073KL is electrically and mechanically compatible. Both components have 3 kOhms ±1% resistance, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and 1210 (3225 Metric) package with 2 terminations. The substitute has a higher power rating (0.5W vs. 0.333W), which is an acceptable upgrade that does not affect circuit performance.

Q: What is the difference between RC1210FR-073KL and AC1210FR-073KL?

A: Both parts are manufactured by YAGEO with identical electrical specifications (3 kOhms ±1%, 0.5W, ±100ppm/°C, -55°C ~ 155°C). The primary difference is that AC1210FR-073KL includes AEC-Q200 automotive qualification, while RC1210FR-073KL does not. Select AC1210FR-073KL for automotive applications; select RC1210FR-073KL for general-purpose applications.

Q: Is CRCW12103K00FKEA compatible with RC3225F302CS?

A: Yes. CRCW12103K00FKEA (Vishay Dale) is electrically and mechanically compatible. It matches the 3 kOhms ±1% resistance, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and 1210 (3225 Metric) package. It includes AEC-Q200 automotive certification and has a 0.5W power rating (upgrade from 0.333W).

Q: Can I use a 0.5W rated resistor in place of a 0.333W rated resistor?

A: Yes. A higher power rating is an acceptable substitution. The 0.5W substitute will operate safely in any circuit designed for the 0.333W original part. Power rating indicates the maximum power the component can dissipate; using a higher-rated component does not degrade performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC3225F302CS, RC1210FR-073KL, AC1210FR-073KL, and CRCW12103K00FKEA are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: What packaging formats are available for these parts?

A: RC3225F302CS is available in standard packaging (format not specified in data). RC1210FR-073KL and AC1210FR-073KL are available in Tape & Reel (TR). CRCW12103K00FKEA is available in Cut Tape (CT) & Digi-Reel®. Confirm packaging requirements with your procurement process.

Q: Do all substitute parts have the same physical dimensions?

A: Dimensions are similar but not identical. RC3225F302CS: 0.126" L x 0.100" W x 0.026" H max. RC1210FR-073KL and AC1210FR-073KL: 0.122" L x 0.102" W x 0.024" H max. CRCW12103K00FKEA: 0.126" L x 0.098" W x 0.024" H max. All fit the 1210 (3225 Metric) package specification and are mechanically compatible in standard PCB layouts.
