Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F1910CS are qualified based on the following critical parameters that must match or exceed the main part specifications:

Electrical Parameters (Must Match):

• Resistance value: 191 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these core requirements. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances and differences in packaging format (Tape & Reel vs. bulk) do not affect functional substitutability. Product status and specific feature sets (such as automotive AEC-Q200 qualification) are noted for application-specific selection but do not disqualify substitution based on electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW1206191RFKEA (Vishay Dale) and RC1206FR-07191RL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring continued availability and manufacturer support. CRCW1206191RFKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-07191RL provides moisture-resistant thick film construction matching the feature set of the main part.

Secondary Substitute (Legacy Status):

ERJ-8ENF1910V (Panasonic Electronic Components) meets all electrical and mechanical specifications with automotive AEC-Q200 qualification. However, this part carries "Not For New Designs" product status, indicating it is suitable for replacement and maintenance applications only, not for new product development.

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating, confirming compatibility with standard PCB assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206191RFKEA directly replace RCS3216F1910CS in existing designs?

A: Yes. Both parts share identical electrical specifications (191 Ohms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and 1206 package dimensions. CRCW1206191RFKEA is available in Tape & Reel packaging versus the main part's standard packaging, but this affects only procurement and assembly logistics, not functional performance.

Q: What is the difference between the anti-sulfur feature of RCS3216F1910CS and the automotive AEC-Q200 qualification of CRCW1206191RFKEA?

A: Anti-sulfur and moisture-resistant properties are material-level protections against environmental degradation. Automotive AEC-Q200 qualification is a reliability standard covering design, manufacturing, and testing processes. These are distinct feature sets; the presence of AEC-Q200 does not replace anti-sulfur protection, and vice versa. Selection depends on application requirements.

Q: Why is ERJ-8ENF1910V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and promotion of this part number. It remains available for replacement and maintenance of existing equipment but should not be selected for new product designs. Use CRCW1206191RFKEA or RC1206FR-07191RL for new applications.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within standard 1206 package tolerances. RCS3216F1910CS and RC1206FR-07191RL measure 0.126" L × 0.063" W with heights of 0.026" and 0.026" respectively. CRCW1206191RFKEA measures 0.126" L × 0.063" W with height 0.024". ERJ-8ENF1910V measures 0.126" L × 0.063" W with height 0.028". These variations do not affect PCB layout or assembly compatibility.

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

A: Yes. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard dry storage and handling procedures apply uniformly across all four part numbers.

Q: Which substitute offers the highest inventory availability?

A: ERJ-8ENF1910V has the highest inventory at 150,996 pieces. However, due to its "Not For New Designs" status, CRCW1206191RFKEA (12,996 pieces) or RC1206FR-07191RL (10,752 pieces) are preferred for new applications requiring active product support.
