Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1912CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 19.1 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel versus bulk) do not affect functional substitutability. Product status and specific feature sets (such as automotive AEC-Q200 qualification or anti-sulfur properties) are noted for application-specific selection but do not preclude substitution at the component level.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW120619K1FKEA (Vishay Dale) and RC1206FR-0719K1L (YAGEO) are both active production parts with full compliance to ROHS3 and equivalent electrical specifications. CRCW120619K1FKEA carries automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-0719K1L maintains moisture-resistant properties consistent with the original RCS3216F1912CS design.

Secondary Substitute (Legacy Status):

ERJ-8ENF1912V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable for replacement or repair applications in existing designs but should not be selected for new product development.

All substitute parts are ROHS3 compliant with MSL rating 1, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW120619K1FKEA replace RCS3216F1912CS in any application?

A: Yes. Both parts share identical resistance (19.1 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW part includes automotive AEC-Q200 qualification, which provides additional reliability assurance for automotive applications.

Q: What is the difference between the physical dimensions listed for each part?

A: Minor variations in length, width, and height (for example, RCS3216F1912CS at 0.126" L vs. RC1206FR-0719K1L at 0.122" L) fall within standard 1206 package tolerances and do not affect PCB footprint compatibility or functional performance.

Q: Why is ERJ-8ENF1912V marked "Not For New Designs"?

A: This designation indicates the part is in legacy status. While it meets all electrical and mechanical specifications for substitution, Panasonic recommends using active production alternatives for new product designs. The part remains suitable for repair and replacement in existing applications.

Q: Does packaging format (Tape & Reel vs. bulk) affect substitutability?

A: No. Packaging format affects logistics and handling but does not impact electrical or mechanical compatibility. All listed substitutes are functionally equivalent regardless of packaging configuration.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the original RCS3216F1912CS specification.
