RC3216F5621CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F5621CS is a 5.62 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 necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for alternative qualified sources meeting identical electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F5621CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Resistance Value: 5.62 kOhms
Tolerance: ±1%
Power Rating: 0.25W (1/4W)
Package / Case: 1206 (3216 Metric)
Composition: Thick Film
Temperature Coefficient: ±100ppm/°C
Operating Temperature Range: -55°C ~ 155°C
Number of Terminations: 2
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed below meet these mandatory parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and optional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution eligibility when electrical and core mechanical specifications remain identical.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-5621ELF (Bourns Inc.), RC1206FR-075K62L (YAGEO), RMCF1206FT5K62 (Stackpole Electronics Inc), and CRCW12065K62FKEA (Vishay Dale) are all classified as Active products with current manufacturing and distribution support. These parts are suitable for new designs and ongoing production requirements.

Secondary Substitute (Not For New Designs):

ERJ-8ENF5621V (Panasonic Electronic Components) carries "Not For New Designs" product status. This part remains electrically and mechanically equivalent but should be reserved for legacy system maintenance, repair, or replacement applications only. New design implementations should prioritize Active-status alternatives.

Discontinued Substitute:

MCR18ERTF5621 (Rohm Semiconductor) is listed as "Discontinued at DiGi Electronics." While electrically and mechanically equivalent, this part should be used only when existing inventory is available and no Active alternatives are feasible.

Compliance Considerations:

All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and environmental requirements matching the original RC3216F5621CS specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW12065K62FKEAHP be used as a substitute for RC3216F5621CS?

A: No. CRCW12065K62FKEAHP has a power rating of 0.75W (3/4W), which exceeds the 0.25W (1/4W) specification of RC3216F5621CS. Although both use 1206 package and 5.62 kOhms ±1% resistance, the different power rating disqualifies it as a direct substitute. This part is listed as a similar alternative only.

Q: What is the difference between Direct and Similar substitute classifications?

A: Direct substitutes meet all mandatory electrical and mechanical parameters identically. Similar substitutes share the same resistance, tolerance, and package but may differ in power rating, certifications, or other secondary specifications. Only Direct substitutes should be used for equivalent replacement.

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

A: Yes. While all parts conform to 1206 (3216 Metric) package specification, individual manufacturers report slight variations in seated height: RC3216F5621CS (0.65mm), CR1206-FX-5621ELF (0.75mm), ERJ-8ENF5621V (0.70mm), RC1206FR-075K62L (0.65mm), RMCF1206FT5K62 (0.70mm), CRCW12065K62FKEA (0.60mm), and MCR18ERTF5621 (0.65mm). These variations remain within standard 1206 package tolerance and do not require PCB redesign.

Q: Can I use automotive-qualified parts (AEC-Q200) in non-automotive applications?

A: Yes. Automotive-qualified parts such as RMCF1206FT5K62, CRCW12065K62FKEA, and ERJ-8ENF5621V exceed standard industrial specifications and are fully compatible with non-automotive applications. AEC-Q200 certification represents additional qualification, not a restriction.

Q: What packaging formats are available for these substitutes?

A: CR1206-FX-5621ELF, ERJ-8ENF5621V, RC1206FR-075K62L, RMCF1206FT5K62, CRCW12065K62FKEA, and CRCW12065K62FKEAHP are supplied in Tape & Reel (TR) format. MCR18ERTF5621 is available in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly process requirements and volume specifications.

Q: Is the RC3216F5621CS moisture-resistant feature replicated in all substitutes?

A: CR1206-FX-5621ELF and RC1206FR-075K62L explicitly specify moisture-resistant construction. ERJ-8ENF5621V, RMCF1206FT5K62, CRCW12065K62FKEA, and MCR18ERTF5621 do not explicitly list moisture resistance in their feature descriptions, though all maintain MSL 1 (Unlimited) rating. For applications requiring explicit moisture-resistant construction, CR1206-FX-5621ELF or RC1206FR-075K62L are recommended.
