Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F2210CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 221 Ohms
• 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)
• Composition: Thick Film
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS3 Compliant
• MSL 1 (Unlimited)
• REACH Unaffected

Substitutes are grouped into two categories: Direct Equivalents (identical 0.25W power rating) and Higher Power Variants (0.75W rating, suitable for applications with additional thermal margin). All listed substitutes maintain identical electrical performance and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (0.25W, 1/4W):

The following parts provide direct electrical and mechanical equivalence to the RCS3216F2210CS:

• CRCW1206221RFKEA (Vishay Dale): Active status, AEC-Q200 certified, compact height profile (0.60mm), suitable for automotive and industrial applications.
• AC1206FR-07221RL (YAGEO): Active status, AEC-Q200 certified, high inventory availability (13,127 pcs), automotive-grade performance.
• RC1206FR-07221RL (YAGEO): Active status, highest inventory availability (125,869 pcs), standard industrial-grade performance.
• RMCF1206FT221R (Stackpole Electronics Inc): Active status, AEC-Q200 certified, highest inventory availability (429,700 pcs), automotive-grade performance.
• CR1206-FX-2210ELF (Bourns Inc.): Active status, high inventory availability (29,218 pcs), standard industrial-grade performance.

Higher Power Variant (0.75W, 3/4W):

• CRCW1206221RFKEAHP (Vishay Dale): Active status, AEC-Q200 certified, pulse-withstanding capability, suitable for applications requiring additional thermal margin or transient protection.

Legacy Status (Not Recommended for New Designs):

• ERJ-8ENF2210V (Panasonic Electronic Components): Product status "Not For New Designs," though AEC-Q200 certified and currently in stock. Use only for replacement or maintenance of existing assemblies.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F2210CS with any of the listed parts?

A: Yes, all listed parts with 0.25W power rating and Active product status provide direct substitution. The CRCW1206221RFKEAHP (0.75W variant) is also compatible but provides higher power dissipation capability. The ERJ-8ENF2210V is compatible but carries "Not For New Designs" status and should be used only for existing assembly maintenance.

Q: What is the difference between the 0.25W and 0.75W variants?

A: The 0.75W variant (CRCW1206221RFKEAHP) maintains identical electrical specifications (221 Ω, ±1%, same temperature coefficient and operating range) but provides three times the power dissipation capability. This allows operation under higher current conditions or provides thermal margin in demanding applications. The 1206 package dimensions remain identical.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 Compliant and REACH Unaffected, matching the compliance profile of the RCS3216F2210CS.

Q: Which substitutes carry AEC-Q200 automotive certification?

A: The following substitutes are AEC-Q200 certified: AC1206FR-07221RL, CRCW1206221RFKEA, CRCW1206221RFKEAHP, ERJ-8ENF2210V, and RMCF1206FT221R. These are suitable for automotive and high-reliability applications.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations and does not require special moisture-controlled storage or handling procedures. All listed parts maintain this rating.

Q: Can I use these substitutes interchangeably on the same PCB?

A: Yes, all 0.25W substitutes are mechanically and electrically interchangeable on the same PCB layout. Minor dimensional variations (height range 0.60mm to 0.75mm) are within standard PCB assembly tolerances. The 0.75W variant is also mechanically compatible but should be selected only if the application requires higher power dissipation.

Q: Which substitute has the highest inventory availability?

A: RMCF1206FT221R (Stackpole Electronics Inc) has the highest inventory availability at 429,700 pieces, followed by RC1206FR-07221RL (YAGEO) at 125,869 pieces.
