CS45SL2GA470JYNKA Equivalent & Substitute Parts

Part Overview

The CS45SL2GA470JYNKA is a 47 pF ceramic capacitor manufactured by TDK Corporation, rated for 300VAC/440VAC operation with SL temperature coefficient. This component is classified as a high-voltage safety-rated capacitor (X1, Y2) designed for through-hole radial mounting in applications requiring reliable AC voltage suppression and filtering. The part maintains Active product status with 1635 units currently in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range, ensuring functional interchangeability in target applications.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	47 pF	Core electrical specification; must match exactly
Tolerance	±5%	Defines acceptable capacitance range; substitutes must meet or exceed
Voltage Rating	300VAC/440VAC	Safety-critical parameter; substitutes must support minimum 440VAC
Temperature Coefficient	SL	Determines capacitance stability across operating range
Operating Temperature	-40°C ~ 125°C	Defines environmental limits; substitutes must cover or exceed range
Safety Ratings	X1, Y2	Regulatory compliance for AC applications; must be maintained
Mounting Type	Through Hole, Radial	Physical installation requirement; must match
Lead Spacing	0.295" (7.50mm)	PCB footprint compatibility; critical for board layout
RoHS Status	ROHS3 Compliant	Environmental regulation compliance

Substitute Part Grouping Explanation

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

Capacitance Value: Must be 47 pF ±5%
Voltage Rating: Must support minimum 300VAC/440VAC
Temperature Coefficient: Must be SL type
Safety Ratings: Must include X1 and Y2 certifications
Mounting Configuration: Must be through-hole radial with formed kinked leads
Lead Spacing: Must be 0.295" (7.50mm) for PCB compatibility
Regulatory Compliance: Must maintain ROHS3 compliance

The substitute part CS45SL2GA470JANKA meets all substitution criteria while offering extended operating temperature range (-55°C ~ 125°C) and automotive-grade qualification (AEC-Q200).

Engineering Selection Recommendations

Both CS45SL2GA470JYNKA and CS45SL2GA470JANKA are Active products from TDK Corporation with identical electrical specifications and safety certifications. Selection between these parts should be based on:

CS45SL2GA470JYNKA is appropriate when:

Compact board layout requires minimum component diameter (7.00mm)
Operating temperature range of -40°C ~ 125°C is sufficient
Standard industrial applications without automotive qualification requirements

CS45SL2GA470JANKA is appropriate when:

Extended low-temperature operation to -55°C is required
Automotive-grade reliability (AEC-Q200) is specified
Slightly larger component diameter (8.00mm) is acceptable within board layout constraints
Higher inventory availability (24751 units) supports supply chain continuity

Both parts maintain ROHS3 compliance and identical lead spacing for PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can CS45SL2GA470JANKA be used as a direct replacement for CS45SL2GA470JYNKA?

A: Yes, provided board layout clearance accommodates the larger component diameter (8.00mm vs 7.00mm). All electrical parameters, safety ratings, and lead spacing are identical.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive-grade qualification standard. This certification is not required for the main part but is present on the substitute, indicating enhanced reliability screening. It does not affect substitution eligibility for non-automotive applications.

Q: Are the temperature coefficient specifications identical?

A: Yes, both parts use SL temperature coefficient. The substitute offers an extended operating range (-55°C ~ 125°C vs -40°C ~ 125°C), which is a superset of the main part's range.

Q: Does the physical size difference affect electrical performance?

A: No. The diameter difference (7.00mm vs 8.00mm) is a mechanical characteristic only. Electrical performance remains identical. Verify PCB layout clearance before substitution.

Q: Are both parts currently available?

A: Yes. CS45SL2GA470JYNKA has 1635 units in stock; CS45SL2GA470JANKA has 24751 units in stock, providing greater supply availability.

Q: What certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry X1/Y2 safety ratings for AC applications. Both are classified under ECCN EAR99 and HTSUS 8532.23.0060.
