SR151C472MAATR2 Equivalent & Substitute Parts

Part Overview

The SR151C472MAATR2 is a 4700 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part maintains Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified to provide design flexibility for procurement, inventory management, and application requirements where tolerance or packaging specifications differ from the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SR151C472MAATR2 is determined by electrical and mechanical parameter alignment. The primary substitutes maintain identical capacitance (4700 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), package type (radial), and lead spacing (0.100"). The key differentiator among substitutes is tolerance specification and packaging format. The SR151C472MAATR2 specifies ±20% tolerance with cut tape (CT) packaging. Substitute parts SR151C472KAR and SR151C472KARTR2 offer tighter ±10% tolerance while maintaining all other electrical and mechanical parameters. Packaging differences (bulk versus cut tape) do not affect electrical performance and represent alternative procurement formats for the same component specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The SR151C472MAATR2 with ±20% tolerance is suitable for general-purpose applications where capacitance variation within this range is acceptable. The SR151C472KAR and SR151C472KARTR2 substitutes offer ±10% tolerance, providing tighter capacitance control for applications requiring improved accuracy. Selection between SR151C472KAR (bulk packaging) and SR151C472KARTR2 (cut tape packaging) depends on procurement and assembly requirements rather than electrical performance. All parts are mechanically and electrically interchangeable within their respective tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can SR151C472KAR replace SR151C472MAATR2 in my design? A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range, physical dimensions, and lead spacing. The SR151C472KAR offers tighter ±10% tolerance compared to the ±20% tolerance of the SR151C472MAATR2. This substitution is electrically and mechanically compatible.

Q: What is the difference between SR151C472KAR and SR151C472KARTR2? A: Both parts are electrically identical with 4700 pF capacitance, ±10% tolerance, and 100V rating. The difference is packaging format: SR151C472KAR is supplied in bulk packaging, while SR151C472KARTR2 is supplied in cut tape (CT) format. Selection depends on your assembly process and procurement requirements.

Q: Does tighter tolerance (±10%) affect circuit performance compared to ±20%? A: Tolerance affects capacitance accuracy but not electrical performance characteristics. ±10% tolerance provides tighter capacitance control, which may be beneficial in applications sensitive to capacitance variation. Both tolerances are within the X7R temperature coefficient specification across the -55°C to 125°C operating range.

Q: Are all substitute parts ROHS3 compliant? A: Yes. SR151C472MAATR2, SR151C472KAR, and SR151C472KARTR2 are all ROHS3 compliant, meeting environmental and regulatory requirements.

Q: Can I use these parts interchangeably on the same PCB? A: Yes. All three parts have identical physical dimensions (0.150" L x 0.100" W), lead spacing (0.100"), and height (0.150" max), making them mechanically interchangeable on through-hole PCB layouts.
