RC3216F4531CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F4531CS is a 4.53 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, operating across -55°C to 155°C temperature range. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package class, resistance value, tolerance, power rating, and operating temperature range. Alternative sources provide design flexibility, supply chain redundancy, and application-specific feature options such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across electrical and mechanical parameters. All identified substitute parts maintain identical resistance value (4.53 kOhms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Substitute parts are grouped into two categories:

Direct Substitutes - Parts with identical specifications and interchangeable performance characteristics:

CR1206-FX-4531ELF (Bourns Inc.)
ERJ-8ENF4531V (Panasonic Electronic Components)
RC1206FR-074K53L (YAGEO)
RMCF1206FT4K53 (Stackpole Electronics Inc)

Similar Substitutes - Parts meeting all critical electrical and mechanical parameters with additional features or certifications:

CRCW12064K53FKEA (Vishay Dale) - Automotive AEC-Q200 qualified
KTR18EZPF4531 (Rohm Semiconductor) - Automotive AEC-Q200 qualified, high voltage rated

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) rating. Physical dimensions remain within acceptable tolerance for 1206 package class applications.

Engineering Selection Recommendations

For Standard Industrial Applications: CR1206-FX-4531ELF (Bourns Inc.) or RC1206FR-074K53L (YAGEO) are recommended. Both parts maintain Active product status, moisture-resistant construction, and full ROHS3 compliance. These options provide equivalent performance to the primary RC3216F4531CS specification.

For Automotive Applications: RMCF1206FT4K53 (Stackpole Electronics Inc) or CRCW12064K53FKEA (Vishay Dale) are specified. Both parts carry AEC-Q200 automotive qualification with Active product status. RMCF1206FT4K53 provides established automotive supply chain support. CRCW12064K53FKEA offers lowest seated height (0.024") for space-constrained layouts.

For High-Voltage Automotive Applications: KTR18EZPF4531 (Rohm Semiconductor) combines AEC-Q200 qualification with high-voltage rating. Active product status ensures continued availability.

Avoid for New Designs: ERJ-8ENF4531V (Panasonic Electronic Components) carries "Not For New Designs" status despite AEC-Q200 qualification. This part is suitable only for legacy system maintenance or existing design continuity.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F4531CS with any of the listed parts without circuit redesign?

A: Yes. All Direct Substitute parts (CR1206-FX-4531ELF, RC1206FR-074K53L, RMCF1206FT4K53) and Similar Substitute parts (CRCW12064K53FKEA, KTR18EZPF4531) maintain identical electrical specifications (4.53 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and 1206 package footprint. No circuit modifications are required.

Q: What is the difference between Direct and Similar substitutes?

A: Direct substitutes provide equivalent performance with identical feature sets (moisture resistance). Similar substitutes add automotive AEC-Q200 qualification or high-voltage rating. Selection depends on application requirements. Standard industrial designs use Direct substitutes; automotive designs use Similar substitutes with AEC-Q200 certification.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within 1206 package tolerance. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm). Height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). All dimensions remain compatible with standard 1206 PCB footprints. Space-constrained designs should specify CRCW12064K53FKEA (0.024" height) or RC3216F4531CS (0.026" height).

Q: Which substitute offers the best supply availability?

A: CR1206-FX-4531ELF (Bourns Inc.) shows highest inventory at 25,659 pieces. RMCF1206FT4K53 (Stackpole Electronics Inc) provides 15,199 pieces with Active status and automotive qualification. Both ensure consistent supply for production requirements.

Q: Can I use ERJ-8ENF4531V in new product designs?

A: No. ERJ-8ENF4531V carries "Not For New Designs" product status. This part is restricted to legacy system support or existing design continuity only. Use RMCF1206FT4K53 or CRCW12064K53FKEA for new automotive designs requiring AEC-Q200 qualification.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all parts. These certifications enable unrestricted use in regulated industrial and consumer applications.

Q: How do I select between RMCF1206FT4K53 and CRCW12064K53FKEA for automotive applications?

A: Both parts meet AEC-Q200 automotive qualification. RMCF1206FT4K53 offers established Stackpole supply chain support. CRCW12064K53FKEA provides lowest seated height (0.024" vs 0.028") for compact PCB layouts. Selection depends on supply chain preference and physical space constraints.
