Equivalent & Substitute Parts for 6LT152KCJCA

Part Overview

The 6LT152KCJCA is a 1500 pF ceramic capacitor rated at 3000V (3kV) with Y5P temperature coefficient, manufactured by KYOCERA AVX in a radial, disc configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The necessity to identify alternative models stems from the obsolete product status, which restricts availability through standard distribution channels. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, and temperature coefficient specifications while accommodating potential variations in physical dimensions and lead configuration.

Key Parameters

Parameter	Value	Specification Basis
Capacitance	1500 pF	Core electrical requirement
Tolerance	±10%	Acceptable capacitance deviation
Voltage Rating	3000V (3kV)	Minimum dielectric strength requirement
Temperature Coefficient	Y5P (B)	Temperature stability classification
Mounting Type	Through Hole	PCB assembly compatibility
Package Type	Radial, Disc	Physical form factor

Substitute Part Grouping Explanation

Substitution eligibility for the 6LT152KCJCA is determined by strict equivalence across the following electrical parameters:

Capacitance Value: 1500 pF (exact match required)
Capacitance Tolerance: ±10% (matching tolerance band)
Voltage Rating: 3000V (3kV) minimum (equal or higher acceptable)
Temperature Coefficient: Y5P (B) (exact match required for thermal stability)
Mounting Technology: Through Hole (PCB assembly method)
Package Configuration: Radial, Disc (physical form factor)

The substitute part S152K47Y5PR63K7R meets all electrical equivalence criteria. Physical dimensions and lead spacing differ from the original part; however, these variations are accommodated within standard through-hole assembly tolerances for radial disc capacitors. The substitute maintains active product status with established supply availability.

Engineering Selection Recommendations

The S152K47Y5PR63K7R is electrically equivalent to the 6LT152KCJCA across all critical parameters: capacitance, tolerance, voltage rating, and temperature coefficient. The substitute part carries active product status with established manufacturing and distribution infrastructure, addressing the procurement constraints imposed by the original part's obsolete classification.

Physical dimension differences require PCB layout verification. The substitute exhibits reduced diameter (12.00mm vs. 13.00mm), increased seated height (16.80mm vs. 6.00mm), and reduced lead spacing (7.50mm vs. 10.00mm). These variations necessitate confirmation that the PCB footprint and component clearances accommodate the substitute geometry.

The substitute's operating temperature range (-30°C to 125°C) is narrower at the lower limit compared to the original (-40°C to 125°C). Applications requiring operation below -30°C require alternative component selection.

The substitute meets ROHS3 compliance, aligning with current regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can S152K47Y5PR63K7R be used as a direct replacement for 6LT152KCJCA without PCB modification?

A: Electrical substitution is valid. Physical substitution requires PCB layout verification due to dimensional differences in diameter, height, and lead spacing. Lead configuration differs (straight vs. kinked formed leads), which may affect insertion and retention characteristics.

Q: What are the critical parameters that define substitution eligibility?

A: Capacitance value (1500 pF), tolerance (±10%), voltage rating (3000V minimum), temperature coefficient (Y5P), mounting type (through hole), and package configuration (radial disc) must match or exceed the original specification. These parameters ensure functional equivalence in the circuit application.

Q: Does the substitute part meet current compliance standards?

A: Yes. S152K47Y5PR63K7R is ROHS3 compliant and maintains REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

Q: Are there temperature range limitations with the substitute?

A: The substitute operates from -30°C to 125°C, compared to the original's -40°C to 125°C range. Applications requiring operation below -30°C must identify alternative components.

Q: What is the impact of different lead spacing on assembly?

A: The substitute's 7.50mm lead spacing differs from the original's 10.00mm spacing. PCB hole pattern verification is required to confirm compatibility with existing through-hole footprints. Lead forming (kinked configuration) may affect insertion force and component retention.
