RCS3216F1331CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1331CS is a 1.33 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 rating and is currently in active production status with 1079 pieces in stock.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from multiple qualified manufacturers offering identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1331CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.33 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Parameters:

• Package type: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All five substitute parts listed below meet these criteria without exception. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances and differences in packaging format (Tape & Reel) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

AC1206FR-071K33L (YAGEO), CR1206-FX-1331ELF (Bourns Inc.), CRCW12061K33FKEA (Vishay Dale), and RC1206FR-071K33L (YAGEO) are all suitable direct replacements. These parts maintain active production status and carry ROHS3 compliance with identical electrical and mechanical specifications. Selection among these options should be based on availability, lead time, and existing supply chain relationships.

Secondary Substitute (Legacy Status):

ERJ-8ENF1331V (Panasonic Electronic Components) meets all electrical and mechanical equivalence criteria but carries a "Not For New Designs" product status. This part is suitable for replacement in existing designs or maintenance applications but should not be selected for new product development.

Compliance Considerations:

All substitute parts are ROHS3 compliant and carry MSL 1 rating, indicating unlimited moisture sensitivity protection. No additional environmental or regulatory constraints apply to substitution decisions.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F1331CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance values (1.33 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No circuit redesign is required.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in manufacturer and minor physical dimensions within standard manufacturing tolerances. Electrical performance and functional behavior are identical. AC1206FR-071K33L and CRCW12061K33FKEA include automotive AEC-Q200 qualification, while CR1206-FX-1331ELF and RC1206FR-071K33L do not. ERJ-8ENF1331V is designated "Not For New Designs."

Q: Why is ERJ-8ENF1331V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development of this product line. While the part remains functionally equivalent and suitable for replacement in existing applications, it should not be selected for new product designs due to potential future availability constraints.

Q: Are there any package or footprint compatibility issues?

A: All parts use the 1206 (3216 Metric) package. Minor variations in physical dimensions (length 3.10mm to 3.20mm, height 0.60mm to 0.75mm) fall within standard PCB design tolerances and do not affect footprint compatibility or solderability.

Q: Do I need to verify compatibility before substitution?

A: Verification is not required from an electrical or mechanical standpoint, as all parameters are identical. However, standard engineering practice recommends confirming part availability, lead times, and cost with your supplier before finalizing procurement decisions.

Q: What is the significance of AEC-Q200 qualification on some parts?

A: AEC-Q200 is an automotive industry qualification standard. AC1206FR-071K33L and CRCW12061K33FKEA carry this certification, indicating suitability for automotive applications. Parts without this certification are equally suitable for general industrial and consumer applications.
