Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F40R2CS are qualified based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 40.2 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Termination count: 2

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these core requirements. Variations in height-seated maximum and exact length dimensions within the 1206 package specification do not affect functional substitution. Additional features such as automotive AEC-Q200 qualification represent enhanced capability and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-40R2ELF (Bourns Inc.) and RC1206FR-0740R2L (YAGEO) are functionally equivalent alternatives with active product status. Both components meet all electrical and mechanical specifications of the RCS3216F40R2CS. CR1206-FX-40R2ELF provides moisture-resistant construction. RC1206FR-0740R2L offers the highest inventory availability (97,157 pieces) among substitute options and maintains moisture-resistant features.

CRCW120640R2FKEA (Vishay Dale) is functionally equivalent with active product status and includes automotive AEC-Q200 qualification. This component is suitable for applications requiring automotive-grade reliability certification.

Secondary Substitute (Legacy Status):

ERJ-8ENF40R2V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries "Not For New Designs" product status. This component is suitable only for replacement or maintenance applications in existing designs. Automotive AEC-Q200 qualification is available with this part.

Compliance Alignment:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity level, ensuring regulatory and environmental compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-40R2ELF replace RCS3216F40R2CS in new designs?

A: Yes. CR1206-FX-40R2ELF meets all electrical specifications (40.2 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), mechanical requirements (1206 package, 2 terminations), and compliance certifications (ROHS3, MSL 1). Product status is active.

Q: What is the difference between the substitute parts?

A: All substitute parts share identical electrical parameters and 1206 package format. Differences exist in: (1) manufacturer features—Vishay Dale CRCW120640R2FKEA and Panasonic ERJ-8ENF40R2V include AEC-Q200 automotive qualification; (2) product status—ERJ-8ENF40R2V is not for new designs; (3) height-seated maximum—ranges from 0.024" to 0.030" within 1206 specification tolerance; (4) inventory availability.

Q: Are height differences between substitute parts significant?

A: Height-seated maximum variations (0.024" to 0.030") fall within standard 1206 package specification tolerances and do not affect functional substitution or PCB assembly compatibility.

Q: Which substitute part has the best availability?

A: RC1206FR-0740R2L (YAGEO) has the highest inventory level at 97,157 pieces in stock.

Q: Can ERJ-8ENF40R2V be used in new product designs?

A: No. ERJ-8ENF40R2V carries "Not For New Designs" product status and is restricted to replacement or maintenance applications in existing designs.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 1 (unlimited) moisture sensitivity level, matching the original RCS3216F40R2CS specification.

Q: Which substitute part is recommended for automotive applications?

A: CRCW120640R2FKEA (Vishay Dale) and ERJ-8ENF40R2V (Panasonic) both include AEC-Q200 automotive qualification. CRCW120640R2FKEA is preferred for new automotive designs due to active product status.
