Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Resistance value: 665 kOhms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of Terminations: 2

Secondary Consideration:

• Power Rating: 0.25W (1/4W) for direct equivalence; higher power ratings (0.75W) are acceptable for applications with power margin requirements

All identified substitute parts meet the primary criteria. The CRCW1206665KFKEAHP variant operates at 0.75W power rating and includes automotive AEC-Q200 qualification and pulse withstanding capability, representing an enhanced specification suitable for demanding applications.

Engineering Selection Recommendations

Direct Equivalents (Active Status, Standard Specifications):

RC1206FR-07665KL (YAGEO) and CRCW1206665KFKEA (Vishay Dale) are direct functional equivalents to the RC3216F6653CS. Both components maintain identical electrical specifications, package dimensions, and compliance certifications. YAGEO RC1206FR-07665KL is available in higher inventory quantity (35,323 pcs). CRCW1206665KFKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability.

Enhanced Specification Alternative:

CRCW1206665KFKEAHP (Vishay Dale) operates at 0.75W power rating with pulse withstanding capability and AEC-Q200 automotive qualification. This component is suitable for applications requiring higher power dissipation margin or automotive environmental conditions. Physical dimensions remain compatible with 1206 package footprints.

Legacy Component:

ERJ-8ENF6653V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries "Not For New Designs" product status. This component is suitable only for legacy system maintenance or repair applications where original component continuity is required.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07665KL replace RC3216F6653CS directly?

A: Yes. RC1206FR-07665KL meets all primary substitution criteria: 665 kOhms ±1% resistance, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. Physical dimensions are compatible with existing PCB layouts.

Q: What is the difference between CRCW1206665KFKEA and CRCW1206665KFKEAHP?

A: CRCW1206665KFKEAHP operates at 0.75W power rating compared to CRCW1206665KFKEA at 0.25W. Both include AEC-Q200 automotive qualification. CRCW1206665KFKEAHP additionally features pulse withstanding capability. Both maintain identical resistance, tolerance, temperature coefficient, and operating temperature specifications.
