RCS3216F392CS Equivalent & Substitute Parts

Part Overview

The RCS3216F392CS is a 3.9 kOhm ±1% 1/4W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant construction with an operating temperature range of -55°C to 155°C. The part maintains Active product status with 934 units in current stock inventory.

Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating) and mechanical parameters (package, dimensions) are equivalent within allowable tolerances, enabling direct circuit board replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS3216F392CS is valid with parts meeting the following criteria:

Critical Electrical Parameters (Must Match):

• Resistance Value: 3.9 kOhms
• Tolerance: ±1%
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C

Critical Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Number of Terminations: 2
• Composition: Thick Film

Power Rating Consideration:

• Primary substitutes: 0.25W (1/4W) rating
• Extended capability: 0.75W (3/4W) rating permissible in same package footprint

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

All identified substitute parts maintain these core parameters, allowing direct replacement in circuit applications without circuit board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Active Status): All substitute parts with Active product status maintain full electrical and mechanical compatibility with the RCS3216F392CS. Selection among AC1206FR-073K9L, CR1206-FX-3901ELF, CRCW12063K90FKEA, RC1206FR-073K9L, and the 0.75W variant CRCW12063K90FKEAHP is determined by supply availability and automotive qualification requirements.

Automotive Applications: For circuits requiring AEC-Q200 automotive qualification, AC1206FR-073K9L, CRCW12063K90FKEA, CRCW12063K90FKEAHP, and ERJ-8ENF3901V provide compliant alternatives.

Extended Power Capability: CRCW12063K90FKEAHP offers 0.75W power rating in the same 1206 package, providing increased pulse withstanding capacity within the identical footprint.

End-of-Life Consideration: ERJ-8ENF3901V is designated "Not For New Designs" despite maintaining electrical and mechanical equivalence, suitable only for redesign situations or repair of existing applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly into my existing circuit design? A: Yes, all parts listed with Active product status meet the electrical and mechanical specifications of the RCS3216F392CS and require no circuit design modification. The ERJ-8ENF3901V is electrically equivalent but is not recommended for new circuit designs due to its "Not For New Designs" status.

Q: What is the difference between 0.25W and 0.75W variants? A: The CRCW12063K90FKEAHP provides enhanced pulse withstanding capability at 0.75W rating within the same 1206 package footprint. Selection depends on circuit power dissipation requirements. The standard RCS3216F392CS is rated 0.25W.

Q: Do automotive-qualified parts like AC1206FR-073K9L work in non-automotive applications? A: Yes. AEC-Q200 qualified parts exceed standard requirements and are suitable for all application categories. Automotive qualification indicates additional validation but does not restrict use to automotive circuits.

Q: What does MSL 1 (Unlimited) mean for moisture handling? A: Moisture Sensitivity Level 1 indicates the component tolerates unlimited floor-life storage without desiccant packaging. Both the main part and all substitutes carry this rating.

Q: Are there size differences between substitute parts? A: All parts conform to 1206 (3216 Metric) package with minor dimensional variations within 0.004" (0.1mm) maximum in length and height. These variations are within standard PCB pad tolerances and do not affect placement or soldering.

Q: Why does the parameter comparison show different inventory levels? A: Inventory levels reflect current stock at the distribution point and change continuously. Selection should prioritize product status and application requirements over inventory availability.
