RC3225F7870CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F7870CS is a 787 Ohm ±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 and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for thick film chip resistor applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F7870CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 787 Ohms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power dissipation capacity (0.5W or greater is acceptable for 0.333W applications)
• Physical dimensions: Minor variations within supplier device package specifications are acceptable provided the 1210 package designation is maintained

The identified substitute parts meet all mandatory parameters while providing equal or superior power handling capability.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210787RFKEA (Vishay Dale) is the primary substitute for new designs. This part maintains Active product status, meets all electrical and mechanical specifications, and provides 0.5W power rating capability. The Vishay Dale CRCW series includes AEC-Q200 automotive qualification, offering enhanced reliability for demanding applications. Inventory availability is substantial at 7101 pieces.

ERJ-14NF7870U (Panasonic Electronic Components) is functionally equivalent but carries a "Not For New Designs" product status designation. This part is suitable only for legacy system maintenance, repair, or continuation of existing production runs where design changes are not permitted. The ERJ-14NF7870U provides 0.5W power rating and AEC-Q200 automotive qualification. Inventory availability is high at 20737 pieces.

For new circuit designs, CRCW1210787RFKEA is the recommended substitute. For existing designs currently using RC3225F7870CS, either substitute part provides electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210787RFKEA or ERJ-14NF7870U be used as direct replacements for RC3225F7870CS?

A: Yes. Both substitute parts match the critical electrical parameters (787 Ohms ±1%, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical specifications (1210 package, 2 terminations). The higher power ratings (0.5W vs. 0.333W) provide additional thermal margin without affecting circuit performance.

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

A: CRCW1210787RFKEA maintains Active product status and is recommended for new designs. ERJ-14NF7870U carries "Not For New Designs" status and should be used only for legacy system support or existing production continuation.

Q: Are there physical dimension differences between these parts?

A: All three parts use the 1210 (3225 Metric) package designation. Minor variations exist within supplier specifications: RC3225F7870CS has maximum seated height of 0.026" (0.66mm), CRCW1210787RFKEA is 0.024" (0.60mm), and ERJ-14NF7870U is 0.028" (0.70mm). These variations remain within standard 1210 package tolerances and do not affect PCB layout or assembly compatibility.

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

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.

Q: Are all parts ROHS3 compliant?

A: Yes. RC3225F7870CS, CRCW1210787RFKEA, and ERJ-14NF7870U are all ROHS3 compliant with REACH Unaffected status.

Q: Which part should be selected for automotive applications?

A: Both CRCW1210787RFKEA and ERJ-14NF7870U include AEC-Q200 automotive qualification. For new automotive designs, CRCW1210787RFKEA is the appropriate choice due to Active product status.
