RC3216F2373CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F2373CS is a 237 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant resistor operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 933 pieces available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package format and performance envelope. Four direct and similar alternatives are available from established manufacturers including Bourns Inc., YAGEO, Vishay Dale, and Panasonic Electronic Components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F2373CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 237 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Compatibility Requirements:

• Package format: 1206 (3216 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)
• Moisture resistance: Required feature (exact match)

Compliance Requirements:

• RoHS3 compliance (mandatory)
• MSL 1 rating (unlimited moisture sensitivity)
• REACH unaffected status

All four substitute parts meet these criteria. Dimensional variations in height and length remain within acceptable tolerances for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Production):

CR1206-FX-2373ELF (Bourns Inc.) and RC1206FR-07237KL (YAGEO) are recommended as primary substitutes. Both parts maintain active production status, identical electrical specifications, and full ROHS3 compliance. Bourns inventory (19,723 pcs) and YAGEO inventory (8,683 pcs) provide supply continuity. Dimensional compatibility is confirmed within PCB assembly tolerances.

Secondary Selection (Automotive-Qualified):

CRCW1206237KFKEA (Vishay Dale) qualifies as a secondary substitute with AEC-Q200 automotive certification. This part is suitable for applications requiring automotive-grade reliability. Inventory availability (14,448 pcs) supports production requirements.

Restricted Selection:

ERJ-8ENF2373V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting all electrical and mechanical specifications. This part is suitable only for legacy system maintenance or existing design continuations. High inventory (85,117 pcs) reflects end-of-life phase-out status.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07237KL replace RC3216F2373CS in existing designs?

A: Yes. RC1206FR-07237KL (YAGEO) is a direct electrical and mechanical equivalent. Identical resistance (237 kOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C) confirm substitution compatibility. Height variation (0.65mm vs. 0.66mm) is within PCB assembly tolerances.

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

A: Direct substitutes (CR1206-FX-2373ELF, RC1206FR-07237KL) are functionally identical with no additional features. Similar substitutes (CRCW1206237KFKEA, ERJ-8ENF2373V) include additional certifications such as AEC-Q200 automotive qualification. All four parts meet the core electrical and mechanical requirements for substitution.

Q: Is CRCW1206237KFKEA suitable for automotive applications?

A: CRCW1206237KFKEA carries AEC-Q200 automotive certification, making it suitable for automotive-grade applications. The RC3216F2373CS does not specify automotive qualification. Selection depends on application requirements.

Q: Why is ERJ-8ENF2373V marked "Not For New Designs"?

A: ERJ-8ENF2373V is in end-of-life phase-out status. Panasonic designates this part unsuitable for new design implementations. Use this part only for legacy system maintenance or existing design continuations where supply from active alternatives is unavailable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (CR1206-FX-2373ELF, RC1206FR-07237KL, CRCW1206237KFKEA, ERJ-8ENF2373V) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the RC3216F2373CS specification.

Q: What packaging formats are available for substitute parts?

A: CR1206-FX-2373ELF, RC1206FR-07237KL, and ERJ-8ENF2373V are supplied in Tape & Reel (TR) format. CRCW1206237KFKEA is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly process requirements.

Q: Can height variations affect PCB assembly compatibility?

A: Height variations among substitutes range from 0.60mm to 0.75mm (CRCW1206237KFKEA to CR1206-FX-2373ELF). These variations remain within standard PCB assembly tolerances for 1206 package components and do not affect reflow soldering or component placement processes.
