Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2552CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence:

Resistance value: 25.5 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 ~ 155°C (exact match required)

Mechanical Equivalence:

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

Compliance & Environmental:

RoHS3 Compliant (required)
Moisture Sensitivity Level 1 (required)
REACH Unaffected status (required)

All substitute parts listed below satisfy these criteria. Variations in physical dimensions (length, width, height) within manufacturing tolerances do not affect functional substitution.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW120625K5FKEA (Vishay Dale), RC1206FR-0725K5L (YAGEO), and RMCF1206FT25K5 (Stackpole Electronics Inc) are qualified substitutes with Active product status. These parts maintain full electrical and mechanical equivalence to the RCS3216F2552CS and are suitable for new designs and ongoing production.

Secondary Substitute (Legacy Status):

ERJ-8ENF2552V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" product status. This part is suitable for replacement applications, field service, and legacy system maintenance only. Use of this part in new designs is not recommended.

Compliance Alignment:

All listed substitutes comply with ROHS3 and REACH requirements, matching the environmental and regulatory profile of the main part. Moisture Sensitivity Level 1 (Unlimited) is maintained across all alternatives, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW120625K5FKEA replace RCS3216F2552CS in new product designs?

A: Yes. CRCW120625K5FKEA is electrically identical (25.5 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and mechanically compatible (1206 package). Both parts are Active status and ROHS3 compliant. Direct substitution is supported.

Q: What is the difference between the main part and substitute parts in terms of features?

A: The RCS3216F2552CS features anti-sulfur and moisture-resistant construction. CRCW120625K5FKEA and RMCF1206FT25K5 include Automotive AEC-Q200 qualification. RC1206FR-0725K5L features moisture-resistant construction. ERJ-8ENF2552V includes Automotive AEC-Q200 qualification but is not recommended for new designs. All parts meet the core electrical and environmental specifications.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within manufacturing tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm). Height ranges from 0.024" to 0.028" (0.60mm to 0.70mm). These variations do not affect PCB layout compatibility or functional performance in 1206 package footprints.

Q: Can ERJ-8ENF2552V be used in production applications?

A: ERJ-8ENF2552V is electrically and mechanically equivalent but carries "Not For New Designs" status. Use is restricted to replacement, repair, and legacy system support. For ongoing production, select from Active status alternatives: CRCW120625K5FKEA, RC1206FR-0725K5L, or RMCF1206FT25K5.

Q: Do all substitute parts have the same Moisture Sensitivity Level?

A: Yes. All listed parts, including the main part RCS3216F2552CS, have Moisture Sensitivity Level 1 (Unlimited). Handling, storage, and reflow requirements are identical across all alternatives.

Q: Which substitute offers the highest inventory availability?
