Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across all electrical and mechanical parameters. The following criteria must be met for a part to function as a direct substitute:

Mandatory Matching Parameters:

• Resistance value: 1.65 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: 1206 (3216 Metric)
• Termination count: 2
• Composition: Thick Film
• RoHS compliance: ROHS3
• MSL rating: 1

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

Direct Substitutes (Active Status): CR1206-FX-1651ELF (Bourns Inc.), RC1206FR-071K65L (YAGEO)

Upgrade Substitute (Active Status with AEC-Q200): AC1206FR-071K65L (YAGEO) — includes automotive qualification

Similar Substitutes (Active or Legacy Status with AEC-Q200): CRCW12061K65FKEA (Vishay Dale), ERJ-8ENF1651V (Panasonic Electronic Components — Not For New Designs)

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (Non-Automotive): CR1206-FX-1651ELF (Bourns Inc.) and RC1206FR-071K65L (YAGEO) are direct functional equivalents to RC3216F1651CS. Both maintain active product status and identical electrical specifications. Selection between these options depends on supply chain availability and procurement lead times.

For Automotive Applications (AEC-Q200 Required): AC1206FR-071K65L (YAGEO) and CRCW12061K65FKEA (Vishay Dale) are qualified substitutes with AEC-Q200 certification. Both are in active production and meet all electrical and mechanical requirements of the main part. AC1206FR-071K65L is preferred for new automotive designs due to active status and YAGEO supply chain continuity.

For Legacy System Support: ERJ-8ENF1651V (Panasonic Electronic Components) carries "Not For New Designs" status and should be used only for maintenance or repair of existing systems where component continuity is required. This part maintains full electrical and mechanical compatibility but is not recommended for new circuit designs.

Dimensional Considerations: All substitute parts fit the 1206 package envelope. Height variations (0.60 mm to 0.75 mm maximum seated height) are within standard PCB assembly tolerances and do not affect circuit board layout or component placement.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071K65L replace RC3216F1651CS directly on the circuit board?

A: Yes. RC1206FR-071K65L meets all electrical specifications (1.65 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical requirements (1206 package, 2 terminations). The slight dimensional difference (3.10 mm vs 3.20 mm length) is within standard 1206 package tolerance and does not affect PCB assembly or circuit function.

Q: What is the difference between AC1206FR-071K65L and RC1206FR-071K65L?

A: Both are YAGEO 1.65 kΩ ±1% 0.25W 1206 resistors with identical electrical performance. AC1206FR-071K65L includes AEC-Q200 automotive qualification and is designated for automotive applications. RC1206FR-071K65L is the standard industrial version. For non-automotive circuits, either part is functionally equivalent.

Q: Why is ERJ-8ENF1651V marked "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this part to legacy status. While ERJ-8ENF1651V remains electrically and mechanically compatible with RC3216F1651CS and carries AEC-Q200 qualification, it should be used only for repair or maintenance of existing systems. New circuit designs should specify active-status alternatives such as CR1206-FX-1651ELF, RC1206FR-071K65L, or AC1206FR-071K65L.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC3216F1651CS and all identified substitute parts (CR1206-FX-1651ELF, RC1206FR-071K65L, AC1206FR-071K65L, CRCW12061K65FKEA, ERJ-8ENF1651V) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use CRCW12061K65FKEA in a non-automotive application?

A: Yes. CRCW12061K65FKEA is a Vishay Dale 1.65 kΩ ±1% 0.25W 1206 resistor with AEC-Q200 qualification. While designed for automotive use, it meets all electrical and mechanical specifications for standard industrial applications and is fully compatible with RC3216F1651CS.

Q: What is the height difference between substitute parts, and does it matter?

A: Seated height varies from 0.60 mm (CRCW12061K65FKEA) to 0.75 mm (CR1206-FX-1651ELF). These variations are within standard 1206 package tolerance (±0.15 mm typical) and do not affect PCB assembly, solder reflow, or component clearance in standard circuit board designs.
