SL151A221JAB Equivalent & Substitute Parts

Part Overview

The SL151A221JAB is a 220 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KYOCERA AVX as part of the SkyCap® SL series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with 1,036 units in stock. Identifying equivalent substitute parts is necessary when the primary part becomes unavailable or when design requirements necessitate alternative compliance certifications, particularly regarding RoHS status.

Substitute Part Grouping Explanation

Substitution eligibility for the SL151A221JAB is determined by strict equivalence across the following critical parameters:

Capacitance value: 220 pF
Tolerance: ±5%
Voltage rating: 100V
Temperature coefficient: C0G/NP0
Operating temperature range: -55°C to 125°C
Mounting type: Through Hole
Package type: Radial
Lead spacing: 0.100" (2.54mm)
Physical dimensions: 0.150" L x 0.100" W (3.81mm x 2.54mm)
Lead style: Straight

The SR151A221JAR meets all these criteria and qualifies as a parametric equivalent. Both parts are manufactured by KYOCERA AVX and share identical electrical and mechanical specifications. The primary distinction lies in series designation (SL versus SR) and RoHS compliance status.

Selection between these parts should be based on regulatory requirements and compliance mandates applicable to the end application. Both parts carry Active product status and are manufactured by KYOCERA AVX, ensuring continued availability and consistent quality. The SR151A221JAR offers higher inventory availability at 2,702 units in stock compared to 1,036 units for the SL151A221JAB.

Frequently Asked Questions (FAQ)

Q: Can the SR151A221JAR be used as a direct replacement for the SL151A221JAB?

A: Yes. The SR151A221JAR is a parametric equivalent with identical capacitance (220 pF), tolerance (±5%), voltage rating (100V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and physical dimensions. Both are through-hole radial components with 0.100" lead spacing and straight leads, making them mechanically and electrically interchangeable.

Q: What is the difference between the SL and SR series designations?

A: The SL and SR designations identify different series within KYOCERA AVX's SkyCap® ceramic capacitor product line. Both series share identical electrical and mechanical specifications for this particular part number. The primary distinction is RoHS compliance status: the SR series (SR151A221JAR) is ROHS3 compliant, while the SL series (SL151A221JAB) is RoHS non-compliant.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts are through-hole radial components with identical lead spacing (0.100"), lead style (straight), and physical dimensions (0.150" L x 0.100" W). PCB layouts and footprints designed for either part will accommodate the other without modification.

Q: Which part should be selected for new designs?

A: Selection should be based on regulatory compliance requirements. If RoHS3 compliance is required, the SR151A221JAR is the appropriate choice. If RoHS compliance is not a design requirement, either part may be used based on availability and supply chain considerations.

Q: How do the inventory levels compare between these parts?

A: The SR151A221JAR has 2,702 units in stock, while the SL151A221JAB has 1,036 units in stock. The SR151A221JAR offers greater immediate availability.
