Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216F27R4CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27.4 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All substitute parts listed maintain these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package envelope and differences in product status or feature sets (such as automotive AEC-Q200 qualification) do not preclude substitution when the core parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-27R4ELF (Bourns Inc.) and RC1206FR-0727R4L (YAGEO) are direct equivalents with Active product status. Both components maintain all mandatory electrical and mechanical parameters identical to the RC3216F27R4CS. Selection between these options is based on supply chain availability and packaging format (Tape & Reel).

Secondary Substitutes (Enhanced Specifications):

CRCW120627R4FKEA (Vishay Dale) is functionally equivalent with the addition of Automotive AEC-Q200 qualification. This component meets all core parameters and provides enhanced reliability certification suitable for automotive applications. Product status is Active.

Legacy Substitute (Not For New Designs):

ERJ-8ENF27R4V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status designation. This component is suitable for replacement and repair applications only and should not be selected for new circuit designs.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-27R4ELF replace RC3216F27R4CS in existing designs?

A: Yes. CR1206-FX-27R4ELF is a direct equivalent with identical resistance, tolerance, power rating, package, composition, temperature coefficient, and operating temperature range. Both components are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the moisture-resistant and automotive AEC-Q200 variants?

A: The RC3216F27R4CS and CR1206-FX-27R4ELF are specified as moisture-resistant thick film resistors. The CRCW120627R4FKEA and ERJ-8ENF27R4V variants include Automotive AEC-Q200 qualification, indicating enhanced reliability testing and qualification for automotive applications. All variants maintain identical core electrical parameters.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within the 1206 package envelope. The RC3216F27R4CS has a maximum seated height of 0.026" (0.66mm), while CR1206-FX-27R4ELF is 0.030" (0.75mm), RC1206FR-0727R4L is 0.026" (0.65mm), CRCW120627R4FKEA is 0.024" (0.60mm), and ERJ-8ENF27R4V is 0.028" (0.70mm). Length dimensions also vary slightly (0.122" to 0.126"). These variations remain within standard 1206 package specifications and do not affect PCB layout compatibility.

Q: Should ERJ-8ENF27R4V be used in new designs?

A: No. ERJ-8ENF27R4V carries a "Not For New Designs" product status. This component is suitable for replacement and repair of existing assemblies only. For new designs, select from CR1206-FX-27R4ELF, RC1206FR-0727R4L, or CRCW120627R4FKEA.

Q: What packaging formats are available for substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format. The RC3216F27R4CS original part does not specify packaging format in the provided data.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (CR1206-FX-27R4ELF, RC1206FR-0727R4L, CRCW120627R4FKEA, and ERJ-8ENF27R4V) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC3216F27R4CS specification.
