Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F6813CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

Resistance value: 681 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 ~ 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturing features (automotive AEC-Q200 certification), and product lifecycle status are secondary considerations that do not affect functional equivalence in standard applications.

Engineering Selection Recommendations

Primary Selection (Active Status): CRCW1206681KFKEA (Vishay Dale) and RC1206FR-07681KL (YAGEO) are both Active product status components with full RoHS3 compliance and unlimited MSL rating. CRCW1206681KFKEA includes automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. RC1206FR-07681KL offers the highest inventory availability (202,199 pcs) and is available in Cut Tape & Digi-Reel® packaging format.

Secondary Selection (Legacy Status): ERJ-8ENF6813V (Panasonic) carries "Not For New Designs" product status. This component meets all electrical and mechanical specifications but is designated for replacement in existing production lines only. Use of this part in new circuit designs is not recommended.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification identical to the original RCS3216F6813CS component.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206681KFKEA directly replace RCS3216F6813CS in existing designs? A: Yes. Both components share identical electrical specifications (681 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C), package dimensions (1206 / 3216 Metric), and compliance certifications (ROHS3, MSL 1). The primary difference is packaging format (Tape & Reel vs. original format) and automotive AEC-Q200 certification on the Vishay part.

Q: What is the significance of the "Not For New Designs" status on ERJ-8ENF6813V? A: This designation indicates the component is in end-of-life phase. While electrically and mechanically equivalent, Panasonic has discontinued this part for new applications. Selection should prioritize Active status alternatives (CRCW1206681KFKEA or RC1206FR-07681KL) for new circuit designs.

Q: Are there dimensional differences between substitute parts? A: Minor variations exist in seated height: RCS3216F6813CS (0.66mm), CRCW1206681KFKEA (0.60mm), ERJ-8ENF6813V (0.70mm), and RC1206FR-07681KL (0.65mm). Length dimension for RC1206FR-07681KL is 3.10mm versus 3.20mm for other parts. These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute offers the best inventory availability? A: RC1206FR-07681KL (YAGEO) provides the highest stock level at 202,199 pcs. CRCW1206681KFKEA (Vishay Dale) offers 32,533 pcs, and ERJ-8ENF6813V (Panasonic) provides 42,617 pcs.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are handling and delivery methods only. Electrical specifications, performance characteristics, and reliability remain identical regardless of packaging format.
