RC3225F7871CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F7871CS is a 7.87 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 724 units currently in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and resistance value. Alternative sources become necessary for supply chain continuity, extended lead time mitigation, or application-specific requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following criteria:

Mandatory Matching Parameters:

• Resistance value: 7.87 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Allowable Variation:

• Power rating: Substitute parts may exceed the 0.333W specification of the main part, provided the package dimensions remain within 1210 (3225 Metric) constraints. Higher power ratings do not compromise circuit compatibility in applications requiring lower power dissipation.

Identified Substitutes:

1. CRCW12107K87FKEA (Vishay Dale) – Matches all mandatory parameters with 0.5W power rating and automotive AEC-Q200 qualification.

2. ERJ-14NF7871U (Panasonic Electronic Components) – Matches all mandatory parameters with 0.5W power rating and automotive AEC-Q200 qualification. Product status is Not For New Designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CRCW12107K87FKEA (Vishay Dale)

This substitute maintains Active product status with full ROHS3 compliance and AEC-Q200 automotive qualification. The 0.5W power rating provides operational margin above the 0.333W requirement of the main part while maintaining identical package footprint and electrical characteristics. Inventory availability is 5318 units.

Secondary Selection: ERJ-14NF7871U (Panasonic Electronic Components)

This substitute meets all electrical and mechanical specifications with AEC-Q200 automotive qualification and ROHS3 compliance. However, the product status is designated as Not For New Designs, limiting its application to legacy system support or replacement scenarios. Inventory availability is 15023 units.

Primary Part Retention: RC3225F7871CS (Samsung Electro-Mechanics)

Recommended for new designs requiring non-automotive specifications. Active product status ensures long-term availability and supply chain stability. Moisture-resistant construction and unlimited MSL rating support standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12107K87FKEA replace RC3225F7871CS in existing designs?

A: Yes. Both components share identical resistance value (7.87 kOhms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The higher power rating (0.5W vs. 0.333W) does not create compatibility issues in circuits designed for the lower power specification.

Q: What is the difference between the two substitute parts?

A: CRCW12107K87FKEA and ERJ-14NF7871U are electrically and mechanically identical. The primary distinction is product status: CRCW12107K87FKEA maintains Active status suitable for new designs, while ERJ-14NF7871U is designated Not For New Designs and should be reserved for legacy applications or replacement inventory.

Q: Are these parts suitable for automotive applications?

A: CRCW12107K87FKEA and ERJ-14NF7871U both carry AEC-Q200 automotive qualification. RC3225F7871CS does not specify automotive rating. Selection depends on application requirements.

Q: Do package dimensions differ between these parts?

A: All three parts use the 1210 (3225 Metric) package format. Dimensional variations are within tolerance: RC3225F7871CS measures 0.126" L x 0.100" W with 0.026" max height; CRCW12107K87FKEA measures 0.126" L x 0.098" W with 0.024" max height; ERJ-14NF7871U measures 0.126" L x 0.098" W with 0.028" max height. These differences do not affect PCB layout compatibility.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All three parts carry this rating, eliminating moisture sensitivity as a selection factor.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your design specifications do not mandate a specific manufacturer or automotive qualification. Electrical performance and mechanical compatibility are equivalent across all three parts within their specified operating parameters.
