Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K4532FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 45.3 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: MSL 1

All four substitute parts meet these criteria. Differences exist only in manufacturer identity, packaging format (Tape & Reel versus Cut Tape), inventory availability, and optional certifications (AEC-Q200 automotive qualification). These differences do not affect electrical or mechanical compatibility in applications where the base specifications are required.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

ERJ-6ENF4532V (Panasonic) and RMCF0805FT45K3 (Stackpole) are both Active products with AEC-Q200 automotive qualification. These are suitable for applications requiring automotive-grade reliability. ERJ-6ENF4532V is available in Cut Tape format with 29,216 pieces in stock. RMCF0805FT45K3 is available in Tape & Reel format with 312,483 pieces in stock, providing the highest inventory availability.

RC0805FR-0745K3L (YAGEO) is an Active product with moisture-resistant thick film composition and the lowest seated height (0.024"). This part is available in Tape & Reel format with 156,650 pieces in stock.

Secondary Substitute (Discontinued Status):

MCR10ERTF4532 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics. While electrically and mechanically equivalent, this part should be selected only when existing inventory must be depleted or when alternative sources confirm continued availability. Current stock is 1,000 pieces.

Compliance Considerations:

All substitute parts maintain REACH compliance status equivalent to the main part. Panasonic ERJ-6ENF4532V and Stackpole RMCF0805FT45K3 carry ROHS3 compliance certification, providing additional regulatory alignment for applications in restricted substance environments.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF4532V replace RMC1/10K4532FTP in any application?

A: Yes. Both parts share identical electrical specifications (45.3 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical package (0805 2012 Metric). The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and AEC-Q200 automotive certification on the Panasonic part. Seated height differs by 0.002" (0.05mm), which is negligible for standard PCB assembly.

Q: What is the significance of AEC-Q200 certification on ERJ-6ENF4532V and RMCF0805FT45K3?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this certification have undergone additional reliability testing for automotive applications. If your application does not require automotive qualification, this certification provides no functional benefit but does not prevent use in non-automotive applications.

Q: Why does RC0805FR-0745K3L have a lower seated height?

A: RC0805FR-0745K3L has a maximum seated height of 0.024" (0.60mm) compared to 0.026" (0.65mm) for most other substitutes. This difference results from manufacturing process variations in thick film composition and does not affect electrical performance. Height becomes relevant only in space-constrained PCB designs with minimal clearance above components.

Q: Is MCR10ERTF4532 still available for new designs?

A: MCR10ERTF4532 is marked as Discontinued at DiGi Electronics. While 1,000 pieces remain in current inventory, this part should not be selected for new production designs. Use RC0805FR-0745K3L, ERJ-6ENF4532V, or RMCF0805FT45K3 for ongoing projects.

Q: What packaging format should I select?

A: Tape & Reel (TR) format is standard for high-volume automated assembly. RMC1/10K4532FTP, RC0805FR-0745K3L, and RMCF0805FT45K3 are available in TR format. Cut Tape (CT) & Digi-Reel® format (ERJ-6ENF4532V) is suitable for lower-volume or mixed-component orders but requires different handling equipment.

Q: Are all substitutes RoHS compliant?

A: The main part RMC1/10K4532FTP is REACH Unaffected. All four substitute parts are ROHS3 Compliant, which exceeds the regulatory requirement and provides additional environmental compliance assurance for applications in restricted substance jurisdictions.
