Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4872CS is determined by strict matching of the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 48.7 kOhms
• 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 to 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of Terminations: 2

All identified substitute parts meet these mandatory electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel versus bulk) do not affect functional substitution. Product status and specific feature sets (such as automotive AEC-Q200 certification or anti-sulfur coating) are noted for application-specific selection but do not prevent substitution at the component level.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW120648K7FKEA (Vishay Dale) and RC1206FR-0748K7L (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturer support. CRCW120648K7FKEA includes automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. RC1206FR-0748K7L provides moisture-resistant construction comparable to the original RCS3216F4872CS anti-sulfur and moisture-resistant features.

Secondary Substitute (Legacy Status):

ERJ-8ENF4872V (Panasonic Electronic Components) is functionally equivalent but carries a "Not For New Designs" product status. This part is suitable for replacement in existing applications or legacy system maintenance where component continuity is required. New circuit designs should prioritize Active-status alternatives.

Compliance and Certification:

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring compatibility with modern manufacturing processes and storage requirements. The Vishay Dale CRCW120648K7FKEA additionally provides AEC-Q200 automotive qualification for applications requiring automotive-grade component specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW120648K7FKEA directly replace RCS3216F4872CS in existing designs?

A: Yes. Both parts share identical electrical specifications (48.7 kOhms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and 1206 package dimensions. The primary difference is packaging format (Tape & Reel versus bulk) and the addition of automotive AEC-Q200 certification on the Vishay part, which does not prevent substitution.

Q: What is the significance of "Not For New Designs" status on ERJ-8ENF4872V?

A: This designation indicates that Panasonic has transitioned this part to legacy status and recommends against its use in new circuit designs. However, the part remains functionally equivalent and suitable for replacement in existing applications or maintenance scenarios where component continuity is required.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within standard tolerances. RCS3216F4872CS measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.026" max height. RC1206FR-0748K7L measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" max height. ERJ-8ENF4872V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" max height. These variations do not affect PCB footprint compatibility or functional performance in standard 1206 package applications.

Q: Does the anti-sulfur feature of RCS3216F4872CS require a specific substitute?

A: No. While RCS3216F4872CS includes anti-sulfur coating and RC1206FR-0748K7L includes moisture-resistant construction, all substitute parts meet the same operating temperature range and MSL 1 rating. Selection between anti-sulfur and moisture-resistant variants depends on specific environmental exposure requirements, not substitution compatibility.

Q: What packaging considerations apply when substituting with Tape & Reel format parts?

A: Tape & Reel packaging (CRCW120648K7FKEA, ERJ-8ENF4872V, RC1206FR-0748K7L) is standard for automated assembly processes. If the original RCS3216F4872CS was supplied in bulk format, substitutes in Tape & Reel format require compatible handling equipment. Component-level electrical and mechanical specifications remain unchanged regardless of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RCS3216F4872CS, CRCW120648K7FKEA, ERJ-8ENF4872V, and RC1206FR-0748K7L are all ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring compatibility with modern manufacturing and environmental regulations.
