Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F17R4CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 17.4 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match)

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• Moisture Sensitivity Level 1 (mandatory)

All identified substitute parts meet these criteria without exception. Substitution does not require design verification or testing, as mechanical and electrical parameters are identical across all qualified alternatives.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW120617R4FKEA (Vishay Dale) and RC1206FR-0717R4L (YAGEO) are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and continued manufacturer support. CRCW120617R4FKEA includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-0717R4L provides moisture-resistant construction matching the original part's environmental protection features.

Secondary Substitute (Legacy Status):

ERJ-8ENF17R4V (Panasonic Electronic Components) meets all electrical and mechanical equivalence criteria and carries AEC-Q200 automotive qualification. However, this part is designated "Not For New Designs," indicating discontinued development support. Use of this substitute is limited to replacement applications in existing production lines or legacy system maintenance where supply continuity is established.

Selection Basis:

All substitutes are qualified based on exact parameter matching across resistance, tolerance, power rating, package dimensions, composition, temperature performance, and compliance certifications. Product status and packaging format (Tape & Reel versus bulk) are secondary considerations that do not affect electrical or mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can CRCW120617R4FKEA replace RCS3216F17R4CS in any application?

A: Yes. CRCW120617R4FKEA is electrically and mechanically equivalent. Both parts share identical resistance (17.4 Ohms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The primary difference is packaging format (Tape & Reel versus bulk) and the addition of AEC-Q200 automotive certification on the Vishay part.

Q: What is the difference between the Samsung RCS3216F17R4CS and YAGEO RC1206FR-0717R4L?

A: Both parts are functionally identical in electrical performance and mechanical dimensions. The Samsung part features anti-sulfur and moisture-resistant properties, while the YAGEO part specifies moisture-resistant construction. Both maintain identical operating temperature ranges, tolerance, and power ratings. The YAGEO part is supplied in Tape & Reel packaging, whereas the Samsung part is supplied in bulk.

Q: Why is ERJ-8ENF17R4V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and support for this product line. While the part remains electrically and mechanically equivalent to the RCS3216F17R4CS, it should be used only for replacement or maintenance of existing systems where supply has been established. New designs should prioritize parts with Active status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitutes—CRCW120617R4FKEA, ERJ-8ENF17R4V, and RC1206FR-0717R4L—are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original RCS3216F17R4CS specification.

Q: Does package format (Tape & Reel versus bulk) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical and mechanical performance remain identical regardless of whether the part is supplied in Tape & Reel or bulk format.

Q: Can I use CRCW120617R4FKEA in automotive applications?

A: Yes. CRCW120617R4FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The original RCS3216F17R4CS does not specify automotive certification, so the Vishay substitute provides enhanced qualification for automotive use cases.
