Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F25R5CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 25.5 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these core requirements and are therefore electrically and mechanically interchangeable with the main part number in standard circuit applications.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW120625R5FKEA (Vishay Dale) and RC1206FR-0725R5L (YAGEO) are recommended as primary substitutes. Both maintain Active product status and provide full electrical and mechanical compatibility with the RCS3216F25R5CS. The CRCW120625R5FKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. The RC1206FR-0725R5L offers the highest inventory availability at 120,575 units and maintains moisture-resistant construction consistent with the main part.

Secondary Substitute (Legacy Status):

ERJ-8ENF25R5V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable for replacement and repair applications in existing designs but should not be selected for new circuit development.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 rating, ensuring regulatory and environmental compatibility across all options.

Frequently Asked Questions (FAQ)

Q: Can CRCW120625R5FKEA directly replace RCS3216F25R5CS in existing designs?

A: Yes. Both parts share identical electrical specifications (25.5 Ohms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and 1206 package dimensions. The CRCW120625R5FKEA includes automotive AEC-Q200 qualification, which provides additional reliability assurance without affecting standard circuit compatibility.

Q: What is the difference between the anti-sulfur feature of RCS3216F25R5CS and the automotive qualification of CRCW120625R5FKEA?

A: The RCS3216F25R5CS specifies anti-sulfur and moisture-resistant construction as primary features. The CRCW120625R5FKEA achieves environmental protection through automotive AEC-Q200 qualification, which includes comprehensive reliability testing. Both approaches ensure component durability; the selection depends on application-specific environmental requirements.

Q: Is RC1206FR-0725R5L suitable for new product designs?

A: Yes. RC1206FR-0725R5L maintains Active product status and is appropriate for new designs. It provides the highest inventory availability and meets all electrical, mechanical, and compliance requirements of the RCS3216F25R5CS.

Q: Why is ERJ-8ENF25R5V marked "Not For New Designs"?

A: The ERJ-8ENF25R5V carries a legacy product status designation. While it remains electrically and mechanically compatible with the RCS3216F25R5CS, Panasonic has discontinued active development for this part number. It remains available for replacement and repair of existing assemblies but should not be selected for new circuit development.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. The RCS3216F25R5CS has a maximum seated height of 0.026" (0.66mm), while CRCW120625R5FKEA measures 0.024" (0.60mm) and ERJ-8ENF25R5V measures 0.028" (0.70mm). These variations remain within standard 1206 package tolerances and do not affect PCB assembly compatibility.

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

A: Yes. All listed substitute parts, including the main part RCS3216F25R5CS, maintain MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
