Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2103CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (210 kOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Package Compatibility: All substitute parts must use the 1206 (3216 Metric) package with 2 terminations. Physical dimensions and height-seated specifications must accommodate the same PCB footprint and assembly processes.

Composition & Construction: Thick film construction is required for all substitutes to maintain electrical performance characteristics and environmental stability.

Compliance & Certifications: All parts must maintain ROHS3 compliance and MSL 1 rating. Additional certifications such as AEC-Q200 automotive qualification are noted but do not restrict substitution for non-automotive applications.

Product Status Consideration: Active status parts are preferred; parts marked "Not For New Designs" remain functionally equivalent but may have limited future availability.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Designs: CR1206-FX-2103ELF (Bourns Inc.), CRCW1206210KFKEA (Vishay Dale), and RC1206FR-07210KL (YAGEO) are all suitable direct substitutes with Active product status. All three maintain identical electrical specifications and ROHS3 compliance. Selection among these three may be based on inventory availability, packaging format (Tape & Reel), or regional supplier preference.

For Automotive Applications: CRCW1206210KFKEA (Vishay Dale) carries AEC-Q200 automotive qualification. ERJ-8ENF2103V (Panasonic Electronic Components) also provides AEC-Q200 certification but is marked "Not For New Designs," limiting its suitability for new automotive program development.

For Legacy or Maintenance Applications: ERJ-8ENF2103V remains functionally equivalent despite "Not For New Designs" status and may be used for field repairs or production of existing designs where supply chain continuity is established.

Physical Considerations: All substitute parts fit the 1206 (3216 Metric) footprint. Height-seated specifications range from 0.024" to 0.030", all within typical PCB assembly clearance tolerances. No design modifications are required for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F2103CS with CR1206-FX-2103ELF in my circuit?

A: Yes. Both parts share identical electrical specifications (210 kOhms ±1%, 0.25W), operate across -55°C to 155°C, and use 1206 package construction. ROHS3 and MSL 1 compliance are equivalent. Direct substitution is supported.

Q: What is the difference between the Samsung RCS3216F2103CS and the Vishay CRCW1206210KFKEA?

A: The primary difference is AEC-Q200 automotive qualification on the Vishay part. Electrically and mechanically, both are identical 210 kOhms ±1% 0.25W 1206 resistors. The Vishay part is suitable for automotive applications; the Samsung part is not qualified for automotive use.

Q: Why is the Panasonic ERJ-8ENF2103V marked "Not For New Designs"?

A: This designation indicates the manufacturer is phasing out this product line. While the part remains functionally equivalent and in stock, it should not be selected for new product development. Use CR1206-FX-2103ELF, CRCW1206210KFKEA, or RC1206FR-07210KL for new designs.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. CR1206-FX-2103ELF, CRCW1206210KFKEA, ERJ-8ENF2103V, and RC1206FR-07210KL are all supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Do I need to change my PCB layout if I switch from RCS3216F2103CS to a substitute part?

A: No. All substitute parts use the 1206 (3216 Metric) package with identical footprint and 2-termination configuration. PCB layout remains unchanged. Height-seated variations (0.024" to 0.030") are within standard assembly tolerances and do not require design modification.

Q: Which substitute part has the lowest profile?

A: CRCW1206210KFKEA (Vishay Dale) has the lowest seated height at 0.024" (0.60mm), compared to 0.026" to 0.030" for other substitutes. This may be relevant for space-constrained applications.

Q: Are all these parts RoHS compliant?

A: Yes. All listed parts, including the main part RCS3216F2103CS and all four substitutes, are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
