RC3216F9311CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F9311CS is a 9.31 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 with a temperature coefficient of ±100ppm/°C. The part is currently Active in product status with ROHS3 compliance and MSL 1 rating. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters across all candidates:

Electrical Parameters (Must Match):

• Resistance value: 9.31 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Number of terminations: 2

Material & Composition (Must Match):

• Composition: Thick Film
• Features: Moisture Resistant

Compliance & Environmental (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All three identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in product status or additional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but are noted for application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-079K31L (YAGEO): This part is the primary direct substitute. It maintains Active product status, matches all electrical and mechanical specifications, and carries ROHS3 compliance with MSL 1 rating. The part is available in Tape & Reel packaging with 59,312 units in stock. Physical dimensions vary slightly (3.10mm L vs. 3.20mm L; 0.65mm H vs. 0.66mm H) but remain within 1206 package tolerances.

CRCW12069K31FKEA (Vishay Dale): This substitute adds AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. It maintains Active product status and all core electrical specifications. Physical dimensions match the original part exactly (3.20mm L x 1.60mm W; 0.60mm H). Inventory availability is 11,090 units in Tape & Reel packaging.

ERJ-8ENF9311V (Panasonic): This part meets all electrical and mechanical requirements with AEC-Q200 automotive qualification. However, its product status is listed as "Not For New Designs," indicating this part is in mature/end-of-life phase. Use this substitute only for legacy system maintenance or when existing design documentation specifies this part number. Inventory shows 49,326 units available in Tape & Reel packaging.

For new designs, select RC1206FR-079K31L or CRCW12069K31FKEA. For automotive applications, CRCW12069K31FKEA is preferred. Avoid ERJ-8ENF9311V for new product development.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-079K31L replace RC3216F9311CS in existing designs?

A: Yes. Both parts share identical electrical specifications (9.31 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), composition (thick film), and environmental ratings (ROHS3, MSL 1). Physical dimensions fall within 1206 package tolerances. The substitute is mechanically and electrically compatible.

Q: What is the difference between the three substitute parts?

A: All three substitutes meet the core electrical and mechanical requirements. CRCW12069K31FKEA and ERJ-8ENF9311V include AEC-Q200 automotive qualification, while RC1206FR-079K31L does not. ERJ-8ENF9311V carries "Not For New Designs" status. For new applications, RC1206FR-079K31L or CRCW12069K31FKEA are recommended.

Q: Are there packaging differences between these parts?

A: The original part (RC3216F9311CS) packaging is listed as "-" (unspecified). All three substitutes are available in Tape & Reel (TR) packaging. If your assembly process requires a specific packaging format, confirm availability with your supplier before selection.

Q: Does the slight variation in physical dimensions affect PCB layout?

A: No. All parts conform to the 1206 (3216 Metric) package standard. Variations in length (3.10mm to 3.20mm), width (1.60mm consistent), and height (0.60mm to 0.70mm) are within package specification tolerances and do not require PCB redesign.

Q: Can I use CRCW12069K31FKEA in non-automotive applications?

A: Yes. AEC-Q200 qualification exceeds standard commercial requirements. CRCW12069K31FKEA is fully compatible with non-automotive applications and offers enhanced reliability margins.

Q: Why is ERJ-8ENF9311V marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase with potential future discontinuation. While currently available and functionally equivalent, it should not be selected for new product development. Use this part only for legacy system support or replacement in existing designs already using this part number.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). ECCN classification is EAR99 for all parts. HTSUS code 8533.21.0030 applies uniformly.
