RC3216F4752CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F4752CS is a 47.5 kOhms ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component is classified as Active product status with moisture-resistant construction and ROHS3 compliance. The RC series resistor is designed for general-purpose applications requiring stable resistance values across extended temperature ranges from -55°C to 155°C.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Resistance Value: 47.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Compatible Variation Parameters:

• Power Rating: 0.25W minimum (higher ratings acceptable for drop-in replacement)
• Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters match
• Packaging Format: Tape & Reel acceptable as equivalent to standard packaging
• RoHS Status: ROHS3 compliance required; non-compliant parts listed separately
• Moisture Resistant Feature: Present in all listed substitutes

Substitute parts are categorized as Direct, Upgrade, or Similar based on feature parity and product status alignment with the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrical and Mechanical Equivalence):

CR1206-FX-4752ELF (Bourns Inc.) and RC1206FR-0747K5L (YAGEO) are direct functional equivalents to RC3216F4752CS. Both parts maintain identical electrical specifications, package dimensions, and ROHS3 compliance. These substitutes are suitable for applications where the original Samsung component is unavailable.

Upgrade Options (Enhanced Specifications):

AC1206FR-0747K5L (YAGEO) and RMCF1206FT47K5 (Stackpole Electronics Inc) provide automotive-grade AEC-Q200 certification in addition to base electrical equivalence. These parts are appropriate for designs requiring automotive-qualified components or enhanced reliability margins. CRCW120647K5FKEAHP (Vishay Dale) offers increased power rating (0.75W) with pulse withstanding capability, suitable for applications with higher thermal or transient stress requirements.

Conditional Substitutes:

CRCW120647K5FKTA (Vishay Dale) matches all electrical and mechanical parameters but carries RoHS non-compliance status and REACH-affected designation. This part is restricted to applications where regulatory exemptions apply or legacy design requirements mandate non-compliant components.

ERJ-8ENF4752V (Panasonic Electronic Components) is classified as "Not For New Designs" despite ROHS3 compliance and AEC-Q200 certification. This designation indicates manufacturer discontinuation trajectory and is unsuitable for new product development.

Selection Criteria:

• For general-purpose replacement: CR1206-FX-4752ELF or RC1206FR-0747K5L
• For automotive applications: AC1206FR-0747K5L or RMCF1206FT47K5
• For high-stress environments: CRCW120647K5FKEAHP
• Avoid: CRCW120647K5FKTA (compliance issues) and ERJ-8ENF4752V (obsolescence trajectory)

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F4752CS with a part having different power rating?

A: Yes, substitution with higher power ratings is acceptable. CRCW120647K5FKEAHP (0.75W) is a valid substitute for the 0.25W RC3216F4752CS. Higher power ratings provide additional thermal margin without affecting electrical performance. Lower power ratings are not acceptable.

Q: What is the difference between Direct, Upgrade, and Similar substitute categories?

A: Direct substitutes (CR1206-FX-4752ELF, RC1206FR-0747K5L) match all specifications of the main part without additional features. Upgrade substitutes (AC1206FR-0747K5L, RMCF1206FT47K5) include automotive AEC-Q200 certification. Similar substitutes include parts with enhanced features (pulse withstanding) or restricted compliance status.

Q: Are all listed substitutes physically compatible with RC3216F4752CS?

A: Yes. All substitutes use identical 1206 (3216 Metric) package format with 0.126" length, 0.063" width, and 2-terminal configuration. Physical PCB footprint compatibility is guaranteed. Height variations (0.024" to 0.030" seated maximum) are within standard component tolerance and do not affect assembly compatibility.

Q: Why is CRCW120647K5FKTA listed if it has RoHS non-compliance?

A: CRCW120647K5FKTA is included for reference in applications where RoHS exemptions apply or legacy designs require non-compliant components. New designs should prioritize ROHS3-compliant alternatives.

Q: What does "Not For New Designs" mean for ERJ-8ENF4752V?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and is transitioning the product to end-of-life status. While currently available in inventory, this part should not be selected for new product designs due to future availability risk.

Q: Can I use these substitutes interchangeably in automotive applications?

A: Only AEC-Q200 certified parts (AC1206FR-0747K5L, CRCW120647K5FKEA, CRCW120647K5FKTA, ERJ-8ENF4752V, RMCF1206FT47K5) are suitable for automotive applications. The base RC3216F4752CS and CR1206-FX-4752ELF lack automotive certification and should not be used in automotive designs.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts carry MSL 1 rating, eliminating moisture sensitivity as a substitution constraint. Standard handling procedures apply without special desiccant or baking requirements.

Q: Are there any dimensional differences that affect PCB layout?

A: Dimensional variations exist within standard tolerances. RC1206FR-0747K5L and AC1206FR-0747K5L measure 0.122" length (versus 0.126" for others), and height ranges from 0.024" to 0.030" seated maximum. These variations are within industry standard component tolerances and do not require PCB layout modification.
