Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4323CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (432 kOhms), tolerance (±1%), and power rating (0.125W / 1/8W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0805 / 2012 Metric) and physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) ensure PCB footprint compatibility. Height variation within seated maximum specifications (0.020" to 0.028" / 0.50mm to 0.70mm) remains within assembly process tolerances.

Environmental & Compliance Requirements: RoHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification must be maintained. Composition (Thick Film) and moisture-resistant construction are preserved across all substitutes.

Packaging Format: Tape & Reel (TR) packaging ensures compatibility with automated assembly equipment and handling procedures.

All identified substitute parts meet these criteria without exception.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07432KL (YAGEO) be used as a direct replacement for RC2012F4323CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (432 kOhms, ±1%, 0.125W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), package format (0805 / 2012 Metric), and compliance status (RoHS3, MSL 1). Physical dimensions and seated height fall within acceptable assembly tolerances.

Q: What is the difference between moisture-resistant and AEC-Q200 qualified substitutes?

A: RC0805FR-07432KL features moisture-resistant construction matching the original RC2012F4323CS specification. CRCW0805432KFKEA (Vishay Dale), ERJ-6ENF4323V (Panasonic), and RMCF0805FT432K (Stackpole) incorporate Automotive AEC-Q200 qualification, which includes moisture resistance plus additional automotive reliability testing and documentation. Both categories are functionally equivalent for the specified electrical and thermal parameters.

Q: Are there any height restrictions when substituting these parts?

A: Seated height maximum specifications range from 0.020" (0.50mm) to 0.028" (0.70mm) across all parts. This variation is within standard PCB assembly process tolerances and does not affect component placement, solder reflow, or functional performance. Verify clearance with specific PCB design constraints if height-sensitive applications exist.

Q: Do all substitute parts maintain the same packaging format?

A: Yes. All identified substitutes are supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated pick-and-place assembly equipment and standard component handling procedures.

Q: Which substitute offers the best supply availability?

A: RC0805FR-07432KL (YAGEO) maintains the highest inventory level at 65,875 units in stock, followed by ERJ-6ENF4323V (Panasonic) at 61,692 units. Both provide immediate availability for high-volume production requirements.
