Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F205CS are qualified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following criteria:

Mandatory Matching Parameters:

• Resistance value: 2 MOhms
• 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
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All five substitute parts listed below meet these mandatory criteria. Dimensional variations within supplier specifications and differences in optional features (such as automotive AEC-Q200 certification or high-voltage capability) do not disqualify substitution eligibility, as these represent enhanced or application-specific capabilities rather than deviations from core electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts satisfy the core electrical and mechanical requirements for direct substitution with the RCS3216F205CS. Selection among these alternatives should be based on the following engineering considerations:

Active Product Status Priority: AC1206FR-072ML (YAGEO), CRCW12062M00FKEA (Vishay Dale), KTR18EZPF2004 (Rohm), and RC1206FR-072ML (YAGEO) carry Active product status and are suitable for new designs. ERJ-8ENF2004V (Panasonic) is marked "Not For New Designs" and should be reserved for legacy system maintenance or replacement applications only.

Automotive Qualification: AC1206FR-072ML, CRCW12062M00FKEA, ERJ-8ENF2004V, and KTR18EZPF2004 carry AEC-Q200 automotive qualification. These parts are appropriate for automotive and high-reliability applications. RC1206FR-072ML and RCS3216F205CS do not carry automotive certification and are suitable for general industrial and consumer applications.

Dimensional Consistency: CRCW12062M00FKEA offers the lowest seated height (0.60mm), while ERJ-8ENF2004V has the highest (0.70mm). AC1206FR-072ML, KTR18EZPF2004, and RC1206FR-072ML maintain 0.65mm height. Length variations (3.10mm vs 3.20mm) are within standard PCB layout tolerances for 1206 packages.

Supply Chain Availability: RC1206FR-072ML (YAGEO) shows the highest inventory level (1,000,100 pcs), followed by ERJ-8ENF2004V (Panasonic, 123,379 pcs) and KTR18EZPF2004 (Rohm, 120,822 pcs). CRCW12062M00FKEA (Vishay Dale) provides 24,124 pcs. AC1206FR-072ML (YAGEO) maintains 7,249 pcs in stock.

Feature Differentiation: KTR18EZPF2004 includes high-voltage capability as an enhanced feature. AC1206FR-072ML emphasizes automotive AEC-Q200 and moisture resistance. CRCW12062M00FKEA and ERJ-8ENF2004V provide automotive AEC-Q200 qualification. RC1206FR-072ML and RCS3216F205CS focus on moisture resistance without automotive certification.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-072ML be used as a direct replacement for RCS3216F205CS?

A: Yes. AC1206FR-072ML meets all mandatory electrical and mechanical parameters: 2 MOhms ±1%, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL Level 1. The addition of AEC-Q200 automotive qualification represents enhanced capability rather than a deviation from core specifications.

Q: What is the significance of the "Not For New Designs" status on ERJ-8ENF2004V?

A: This designation indicates that Panasonic has transitioned this product line and is not recommending it for new circuit designs. While ERJ-8ENF2004V remains electrically and mechanically equivalent to RCS3216F205CS, it should be used only for replacement or maintenance of existing systems. For new designs, select from AC1206FR-072ML, CRCW12062M00FKEA, KTR18EZPF2004, or RC1206FR-072ML.

Q: Are the dimensional differences between substitute parts significant?

A: Dimensional variations are minor and within standard 1206 package tolerances. Length differences (3.10mm vs 3.20mm) and height variations (0.60mm to 0.70mm) do not affect PCB footprint compatibility or electrical performance. These variations reflect normal manufacturing tolerances across different suppliers and do not disqualify substitution.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select from AC1206FR-072ML, CRCW12062M00FKEA, ERJ-8ENF2004V, or KTR18EZPF2004, all of which carry AEC-Q200 qualification. Among these, AC1206FR-072ML, CRCW12062M00FKEA, and KTR18EZPF2004 are preferred due to Active product status. KTR18EZPF2004 offers additional high-voltage capability if required by the application.

Q: What is the difference between the two YAGEO options: AC1206FR-072ML and RC1206FR-072ML?

A: Both are YAGEO 2 MOhms ±1% 1206 thick film resistors with identical electrical specifications. AC1206FR-072ML carries AEC-Q200 automotive qualification and is designated for automotive applications. RC1206FR-072ML is a general-purpose variant without automotive certification but offers significantly higher inventory availability (1,000,100 pcs vs 7,249 pcs). Select AC1206FR-072ML for automotive use; select RC1206FR-072ML for general industrial and consumer applications requiring high availability.

Q: Can I mix different substitute parts within the same circuit board?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 2 MOhms ±1% 0.25W 1206 resistor function. Mixing different manufacturers or part numbers within the same design does not affect circuit performance, provided each part meets the specified parameters. This approach can optimize supply chain flexibility and cost management.

Q: What packaging formats are available for these substitute parts?

A: AC1206FR-072ML and RC1206FR-072ML are supplied in Cut Tape (CT) & Digi-Reel® format. CRCW12062M00FKEA, ERJ-8ENF2004V, and KTR18EZPF2004 are supplied in Tape & Reel (TR) format. Select packaging based on your assembly process requirements and volume needs.

Q: Are all substitute parts REACH compliant?

A: Yes. All substitute parts listed carry REACH Unaffected status, indicating compliance with REACH regulations. All parts are also ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the RCS3216F205CS specifications.
