Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F6491CS are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 6.49 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

Power Rating Consideration: Substitute parts are grouped into two categories based on power rating:

• Direct Equivalents (0.25W / 1/4W): AC1206FR-076K49L, CR1206-FX-6491ELF, CRCW12066K49FKEA, ERJ-8ENF6491V, RC1206FR-076K49L
• Higher Power Rating (0.75W / 3/4W): CRCW12066K49FKEAHP (suitable for applications requiring increased power dissipation capability while maintaining all other electrical parameters)

All substitute parts maintain identical electrical performance characteristics and are suitable for direct replacement in applications designed for the RCS3216F6491CS.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: Select from parts with Active product status: AC1206FR-076K49L, CR1206-FX-6491ELF, CRCW12066K49FKEA, CRCW12066K49FKEAHP, or RC1206FR-076K49L. These parts maintain full manufacturing support and long-term availability.

For Automotive Applications: Parts rated for AEC-Q200 compliance include AC1206FR-076K49L, CRCW12066K49FKEA, CRCW12066K49FKEAHP, and ERJ-8ENF6491V. These are suitable for automotive-grade circuit designs.

For Standard Industrial Applications: CR1206-FX-6491ELF and RC1206FR-076K49L provide moisture-resistant thick film construction without automotive qualification, suitable for general industrial and consumer electronics applications.

For Higher Power Dissipation Requirements: CRCW12066K49FKEAHP offers 0.75W (3/4W) power rating with pulse-withstanding capability while maintaining all other electrical specifications of the RCS3216F6491CS.

Avoid for New Designs: ERJ-8ENF6491V carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12066K49FKEAHP be used as a direct replacement for RCS3216F6491CS?

A: CRCW12066K49FKEAHP is electrically compatible with RCS3216F6491CS for all parameters except power rating (0.75W vs. 0.25W). It can be used in applications where the original 0.25W rating is sufficient, and the higher power rating provides additional thermal margin. Verify circuit design does not depend on the specific power rating specification.

Q: What is the difference between AC1206FR-076K49L and RC1206FR-076K49L?

A: Both are YAGEO 1206 resistors with identical electrical specifications (6.49 kOhms, ±1%, 0.25W). AC1206FR-076K49L includes automotive AEC-Q200 qualification, while RC1206FR-076K49L is standard industrial grade. Select AC1206FR-076K49L for automotive applications; RC1206FR-076K49L for general industrial use.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging. The RCS3216F6491CS packaging format is not specified in the provided data. Verify packaging compatibility with your procurement and assembly requirements.

Q: Why is ERJ-8ENF6491V marked "Not For New Designs"?

A: ERJ-8ENF6491V carries this status from the manufacturer. While electrically equivalent and currently in stock (51,138 units), it should not be selected for new product development. Use active-status alternatives for new designs to ensure long-term supply continuity.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the RCS3216F6491CS compliance profile.

Q: What are the physical dimension differences between substitute parts?

A: Physical dimensions vary slightly across manufacturers. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). Verify PCB layout and assembly clearances if space constraints exist.
