Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F28R7CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 28.7 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 or wider range acceptable)

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 status
• Moisture Sensitivity Level 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard 1206 tolerances and differences in specific feature sets (automotive certification, anti-sulfur coating) do not affect functional substitutability when electrical and mechanical core parameters align.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW120628R7FKEA (Vishay Dale) and RC1206FR-0728R7L (YAGEO) are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and continued manufacturing support. CRCW120628R7FKEA includes automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. RC1206FR-0728R7L provides moisture-resistant construction comparable to the original RCS3216F28R7CS.

Secondary Substitute (Legacy Status):

ERJ-8ENF28R7V (Panasonic Electronic Components) meets all electrical and mechanical equivalence criteria and carries AEC-Q200 automotive certification. However, this part is designated "Not For New Designs," indicating discontinued development status. Use this substitute only when existing inventory constraints or legacy system requirements necessitate its selection.

Selection Basis:

All substitutes are qualified based on exact matching of resistance value, tolerance, power rating, package format, composition, temperature coefficient, and operating temperature range. RoHS3 compliance and MSL Level 1 rating are maintained across all options. Product status and certification levels (automotive AEC-Q200) are provided as additional selection criteria for specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW120628R7FKEA directly replace RCS3216F28R7CS in existing designs?

A: Yes. Both parts share identical electrical specifications (28.7 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical package format (1206 / 3216 Metric). Physical dimensions vary within standard 1206 tolerances (CRCW height 0.024" vs. RCS height 0.026"), which does not affect circuit performance or PCB assembly compatibility.

Q: What is the difference between the anti-sulfur feature of RCS3216F28R7CS and the automotive AEC-Q200 rating of CRCW120628R7FKEA?

A: Anti-sulfur coating protects against sulfur-containing environmental contaminants in specific industrial applications. AEC-Q200 certification indicates automotive-grade reliability testing and qualification. These are distinct feature sets addressing different application environments. Selection depends on end-use requirements rather than functional equivalence.

Q: Why is ERJ-8ENF28R7V marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued active development of this product line. While the part remains functionally equivalent and currently in stock (26253 units), it is not recommended for new circuit designs due to uncertain long-term availability. Use only when legacy system compatibility or existing inventory constraints require it.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RCS3216F28R7CS, CRCW120628R7FKEA, ERJ-8ENF28R7V, and RC1206FR-0728R7L are all ROHS3 Compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for these substitutes?

A: CRCW120628R7FKEA, ERJ-8ENF28R7V, and RC1206FR-0728R7L are supplied in Tape & Reel (TR) format, standard for automated PCB assembly. Packaging format does not affect electrical or mechanical compatibility; it addresses supply chain and manufacturing process requirements.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts operate across the identical temperature range (-55°C to 155°C) with matching temperature coefficient (±100ppm/°C). Thermal performance is equivalent across all substitutes.
