RCS3216F6341CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F6341CS is a 6.34 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is currently active in production with 714 pieces available in stock.

Substitute parts are identified when they maintain identical electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical compatibility (package type, footprint dimensions, termination count) while potentially offering alternative manufacturing sources, packaging formats, or enhanced feature sets such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F6341CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 6.34 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 Equivalence Requirements:

• Package type: 1206 (3216 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Footprint compatibility: 0.126" L x 0.063" W nominal dimensions

Compliance Requirements:

• RoHS3 compliance (mandatory)
• Moisture Sensitivity Level 1 (unlimited)

All three identified substitute parts meet these core equivalence criteria. Variations in height (seated maximum), packaging format (tape & reel vs. bulk), and optional features (automotive AEC-Q200 qualification, anti-sulfur coating) do not affect functional substitutability but may influence selection based on application requirements and supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW12066K34FKEA (Vishay Dale) and RC1206FR-076K34L (YAGEO) are functionally equivalent alternatives with active product status. Both maintain identical electrical and mechanical specifications. CRCW12066K34FKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-076K34L provides moisture-resistant thick film construction aligned with the original part's environmental protection features.

Secondary Substitute (Legacy Status):

ERJ-8ENF6341V (Panasonic Electronic Components) meets all electrical and mechanical equivalence criteria but carries "Not For New Designs" product status. This part is suitable for replacement applications, field service, and legacy system maintenance where existing inventory or supply chain continuity is prioritized. New design implementations should utilize active-status alternatives.

Selection Criteria:

• For new designs: Select from CRCW12066K34FKEA or RC1206FR-076K34L
• For automotive applications: CRCW12066K34FKEA (AEC-Q200 qualified)
• For legacy system replacement: ERJ-8ENF6341V acceptable if supply constraints exist
• For general industrial applications: Any active-status substitute provides equivalent performance

Frequently Asked Questions (FAQ)

Q: Can CRCW12066K34FKEA directly replace RCS3216F6341CS in existing designs?

A: Yes. Both parts share identical electrical specifications (6.34 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), identical 1206 package footprint, and equivalent mechanical dimensions. Seated height difference (0.024" vs. 0.026") is within standard PCB assembly tolerances and does not affect functionality or placement.

Q: What is the significance of AEC-Q200 qualification on CRCW12066K34FKEA?

A: AEC-Q200 is an automotive industry standard qualification indicating enhanced reliability testing and quality assurance. This certification is required for automotive applications but is optional for general industrial, consumer, or commercial electronics. Non-automotive applications do not require this qualification.

Q: Why is ERJ-8ENF6341V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has transitioned this product line and recommends alternative parts for new development. However, the part remains functionally equivalent and is suitable for replacement, repair, and legacy system support where existing designs are already in production.

Q: Are there any height restrictions that would prevent substitution?

A: The seated height variations (0.024" to 0.028" maximum) are all within standard 1206 package specifications and PCB assembly clearance requirements. No height-related substitution restrictions apply to these parts.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All four parts (RCS3216F6341CS, CRCW12066K34FKEA, ERJ-8ENF6341V, RC1206FR-076K34L) are rated MSL 1 (Unlimited), indicating no moisture-related handling or storage restrictions during assembly and deployment.

Q: Which substitute offers the best long-term supply availability?

A: CRCW12066K34FKEA (Vishay Dale) and RC1206FR-076K34L (YAGEO) both carry active product status with substantial inventory levels (21,113 and 22,740 pieces respectively), indicating stable long-term availability. ERJ-8ENF6341V, despite higher inventory (56,625 pieces), has "Not For New Designs" status, suggesting potential future discontinuation.
