Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F2100CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 210 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

All identified substitute parts meet these mandatory parameters. Substitute parts are further categorized by product status and additional certifications:

Direct Substitutes (Active Status): RC1206FR-07210RL (YAGEO), CR1206-FX-2100ELF (Bourns Inc.)

Upgrade Substitutes (Active Status with AEC-Q200): AC1206FR-07210RL (YAGEO)

Similar Substitutes (Active or Legacy Status with AEC-Q200): CRCW1206210RFKEA (Vishay Dale), ERJ-8ENF2100V (Panasonic Electronic Components)

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (Non-Automotive): RC1206FR-07210RL (YAGEO) and CR1206-FX-2100ELF (Bourns Inc.) are direct functional equivalents to the RC3216F2100CS. Both parts maintain active production status and identical electrical and thermal specifications. Selection between these options is based on procurement availability and supply chain requirements.

For Automotive Applications: AC1206FR-07210RL (YAGEO) and CRCW1206210RFKEA (Vishay Dale) are qualified substitutes with Automotive AEC-Q200 certification. These parts are suitable for automotive-grade applications requiring enhanced reliability and qualification standards. Both maintain active production status.

Legacy Consideration: ERJ-8ENF2100V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable only for sustaining production of existing designs and should not be selected for new development.

Physical Dimension Variations: Minor variations in seated height exist across substitute parts (0.024" to 0.030" maximum). These variations remain within typical PCB assembly tolerances and do not affect functional compatibility in standard applications. Verification against specific PCB design constraints is required only for applications with height-critical placement requirements.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07210RL be used as a direct replacement for RC3216F2100CS?

A: Yes. RC1206FR-07210RL meets all mandatory electrical, thermal, and mechanical parameters. Both parts are 210 Ohm ±1% 0.25W thick film resistors in the 1206 package with identical temperature coefficients and operating ranges. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the standard and automotive-qualified substitutes?

A: AC1206FR-07210RL and CRCW1206210RFKEA include Automotive AEC-Q200 certification, indicating qualification for automotive applications with enhanced reliability requirements. The base electrical and thermal specifications remain identical to standard versions. Selection depends on application requirements, not electrical performance.

Q: Are there physical differences between substitute parts that affect PCB assembly?

A: Seated height varies slightly across manufacturers: RC3216F2100CS (0.026"), CR1206-FX-2100ELF (0.030"), RC1206FR-07210RL (0.026"), AC1206FR-07210RL (0.026"), CRCW1206210RFKEA (0.024"), and ERJ-8ENF2100V (0.028"). These variations are within standard PCB assembly tolerances. Length and width dimensions are nominally equivalent (3.20mm x 1.60mm or 3.10mm x 1.60mm). Verification against specific PCB design height constraints is required only for space-critical applications.

Q: Why is ERJ-8ENF2100V marked "Not For New Designs"?

A: ERJ-8ENF2100V carries a legacy product status indicating the manufacturer is not recommending this part for new design implementations. The part remains functionally equivalent and suitable for sustaining production of existing designs. New designs should select from parts with active production status.

Q: Can substitute parts be mixed within a single assembly?

A: Yes. All substitute parts meet identical electrical specifications (210 Ohm ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C). Mixing parts from different manufacturers within a single PCB assembly is permissible from an electrical and thermal standpoint. Supply chain and procurement policies may impose additional constraints on part mixing.

Q: What packaging formats are available for these substitutes?

A: All identified substitute parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The RC3216F2100CS primary part is supplied in standard packaging. Packaging format compatibility should be confirmed with procurement requirements before part selection.

Q: Are all substitute parts REACH compliant?

A: Yes. All identified substitute parts carry REACH Unaffected status, indicating compliance with REACH regulations. The primary part RC3216F2100CS also maintains REACH Unaffected status.
