Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RVC1206FT249K are qualified based on the following criteria:

Electrical Parameters: Resistance value (249 kOhms), tolerance (±1%), power rating (0.25W), composition (thick film), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Parameters: Package type (1206 / 3216 Metric) and termination count (2) must be identical to ensure PCB footprint compatibility.

Environmental Ratings: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL rating (1) must be maintained.

Packaging Format: Substitutes may differ in delivery format (Tape & Reel vs. Cut Tape) without affecting circuit performance.

Optional Enhancements: Some substitutes include automotive AEC-Q200 qualification or high-voltage features, which provide additional reliability margins for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FG249K replace RVC1206FT249K in any application? A: Yes. Both parts share identical electrical specifications (249 kOhms ±1%, 0.25W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 1206 package. The RMCF series includes automotive AEC-Q200 qualification, which provides additional reliability screening without affecting standard circuit operation.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Packaging format affects component delivery and handling during assembly. Tape & Reel is suitable for automated pick-and-place equipment, while Cut Tape is used for manual or semi-automated assembly. Both formats contain identical components with no electrical or mechanical differences.

Q: Is KTR18EZPF2493 suitable for high-voltage applications? A: KTR18EZPF2493 includes high-voltage features and AEC-Q200 automotive qualification. However, the 0.25W power rating and 1206 package dimensions remain unchanged. Application suitability depends on specific circuit voltage and current requirements.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating 1, meeting standard environmental and manufacturing requirements.

Q: Can dimensions vary between substitute parts? A: Slight dimensional variations exist within the 1206 package specification. The RVC1206FT249K measures 0.122" L × 0.061" W (3.10mm × 1.55mm), while RMCF1206FG249K measures 0.126" L × 0.063" W (3.20mm × 1.60mm), and CRCW1206249KFKEAC measures 0.120" L × 0.061" W (3.05mm × 1.55mm). These variations remain within standard 1206 footprint tolerances and do not affect PCB compatibility.
