Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RMC1/8K4752FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 47.5 kOhms
• 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)

All four substitute parts listed meet these electrical and mechanical requirements. Substitutes differ only in manufacturer identity, product status classification, and optional certifications (automotive AEC-Q200 qualification or moisture-resistant features). These differences do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications: RC1206FR-0747K5L (YAGEO) is the primary substitute. This part maintains Active product status, carries ROHS3 compliance, and includes moisture-resistant features. It offers the highest inventory availability (111,332 pcs) and ensures long-term supply continuity.

For Automotive Applications: RMCF1206FT47K5 or RMCF1206FG47K5 (both Stackpole Electronics Inc) are appropriate selections. Both parts carry AEC-Q200 automotive qualification, maintain Active product status, and provide ROHS3 compliance. RMCF1206FT47K5 offers superior inventory depth (50,313 pcs).

For Legacy System Maintenance: ERJ-8ENF4752V (Panasonic) is electrically equivalent but carries "Not For New Designs" status. This part is suitable only for replacement in existing systems where design freeze conditions apply. Inventory availability is adequate (16,652 pcs).

Dimensional Considerations: All substitute parts are housed in 1206 (3216 Metric) packages. Minor dimensional variations exist: RMC1/8K4752FTP and RC1206FR-0747K5L measure 0.122" L × 0.063" W, while ERJ-8ENF4752V and both Stackpole variants measure 0.126" L × 0.063" W. Height differences range from 0.025" to 0.028" maximum seated height. These variations remain within standard PCB layout tolerances for 1206 footprints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF4752V replace RMC1/8K4752FTP in new designs? A: No. ERJ-8ENF4752V carries "Not For New Designs" product status. This classification indicates the manufacturer does not recommend this part for new circuit designs. Use RC1206FR-0747K5L, RMCF1206FG47K5, or RMCF1206FT47K5 for new designs.

Q: What is the difference between RMCF1206FG47K5 and RMCF1206FT47K5? A: Both parts are manufactured by Stackpole Electronics Inc and are electrically and mechanically identical. They share the same resistance (47.5 kOhms), tolerance (±1%), power rating (0.25W), package (1206), and certifications (AEC-Q200). The difference lies in internal manufacturing process designation. Selection between them depends on inventory availability and supplier preference.

Q: Are all substitute parts RoHS compliant? A: RC1206FR-0747K5L, ERJ-8ENF4752V, RMCF1206FG47K5, and RMCF1206FT47K5 are all ROHS3 compliant. RMC1/8K4752FTP does not specify RoHS status in the provided data.

Q: Do substitute parts fit the same PCB footprint? A: Yes. All parts use the 1206 (3216 Metric) package. Minor dimensional variations (0.122" to 0.126" length and 0.025" to 0.028" height) are within standard 1206 footprint tolerances and do not require PCB redesign.

Q: Which substitute offers the best supply availability? A: RC1206FR-0747K5L (YAGEO) provides the highest inventory level at 111,332 pcs. RMCF1206FT47K5 (Stackpole) offers the second-highest availability at 50,313 pcs.

Q: Can I use automotive-qualified parts (AEC-Q200) in non-automotive applications? A: Yes. Automotive-qualified parts exceed standard requirements and are suitable for any application. RMCF1206FG47K5 and RMCF1206FT47K5 can be used in general-purpose circuits without restriction.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture-control storage conditions. All listed parts share this rating, eliminating moisture-related supply chain constraints.
