RC3216F9091CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F9091CS is a 9.09 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 1084 pieces available in inventory.

Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical parameters (package type, dimensions, termination count) match the original component. Alternative sources ensure supply chain continuity and design flexibility across equivalent product lines.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

• Resistance value: 9.09 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match)

Mechanical Equivalence Requirements:

• Package type: 1206 (3216 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Composition: Thick Film (exact match)

Compliance Requirements:

• RoHS3 compliance (required)
• MSL 1 rating (required)
• REACH unaffected status (required)

All identified substitute parts meet these criteria. Parts are further categorized as "Direct" substitutes (identical feature sets) or "Similar" substitutes (additional features such as automotive AEC-Q200 qualification that do not conflict with base specifications).

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs:

CR1206-FX-9091ELF (Bourns Inc.), RC1206FR-079K09L (YAGEO), CRCW12069K09FKEA (Vishay Dale), and RMCF1206FT9K09 (Stackpole Electronics Inc) are all suitable direct substitutes. All maintain active product status, full ROHS3 compliance, and MSL 1 rating. Selection among these options may be based on supplier availability, lead time, packaging format (Tape & Reel), or regional sourcing preferences.

For Automotive Applications:

CRCW12069K09FKEA and RMCF1206FT9K09 include AEC-Q200 automotive qualification. These parts are appropriate for designs requiring automotive-grade reliability without introducing incompatible specifications.

Not Recommended for New Designs:

ERJ-8ENF9091V carries "Not For New Designs" status from Panasonic Electronic Components. While electrically and mechanically equivalent, this designation indicates the manufacturer is discontinuing active support. Use only for legacy system maintenance or replacement applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F9091CS with any of the listed parts in existing designs?

A: Yes. CR1206-FX-9091ELF, RC1206FR-079K09L, CRCW12069K09FKEA, and RMCF1206FT9K09 are electrically and mechanically equivalent with active product status. ERJ-8ENF9091V is equivalent but marked "Not For New Designs." All meet identical electrical specifications (9.09 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package requirements (1206, 2 terminations).

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: Direct substitutes match all base specifications without additional features. Similar substitutes include supplementary qualifications (such as AEC-Q200 automotive certification) that do not conflict with or alter the core electrical and mechanical parameters. Both categories are functionally interchangeable for the specified application.

Q: Are there dimensional differences I should consider?

A: Yes. While all parts use the 1206 package, seated heights vary slightly: RC3216F9091CS (0.66mm), CR1206-FX-9091ELF (0.75mm), RC1206FR-079K09L (0.65mm), CRCW12069K09FKEA (0.60mm), ERJ-8ENF9091V (0.70mm), and RMCF1206FT9K09 (0.70mm). Length dimensions also vary between 3.10mm and 3.20mm. Verify PCB layout clearances if height or length constraints exist.

Q: Which substitute has the best inventory availability?

A: RC1206FR-079K09L (YAGEO) has the highest inventory at 161,229 pieces. CR1206-FX-9091ELF (Bourns) has 23,754 pieces. CRCW12069K09FKEA (Vishay Dale) has 18,817 pieces. RMCF1206FT9K09 (Stackpole) has 16,805 pieces. ERJ-8ENF9091V (Panasonic) has 87,472 pieces but is not recommended for new designs.

Q: Can I use CRCW12069K09FKEA or RMCF1206FT9K09 in non-automotive applications?

A: Yes. AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits. These parts meet all base specifications and are suitable for any application requiring a 9.09 kΩ ±1% 0.25W 1206 resistor.

Q: Is ERJ-8ENF9091V still available for purchase?

A: Yes, 87,472 pieces are in stock. However, the "Not For New Designs" status indicates Panasonic is phasing out this product line. Use only for replacement or legacy system support where the original part number is required.

Q: Do all substitutes have identical RoHS and MSL ratings?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) rating and REACH unaffected status, matching the original RC3216F9091CS specifications.
