Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS65ZU2GA102MYGKA is determined by the following critical parameters:

Primary Compatibility Criteria:

• Capacitance value: 1000 pF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: Minimum 300VAC/440VAC capability
• Safety ratings: X1, Y2 (required for safety applications)
• Mounting type: Through Hole (required for PCB compatibility)
• Lead spacing: 0.295" (7.50mm) (required for footprint compatibility)
• Package type: Radial, Disc (required for mechanical fit)

Secondary Compatibility Considerations:

• Temperature coefficient: Z5U preferred; E or Y5U acceptable if operating temperature range remains within -25°C ~ 125°C
• Operating temperature range: Must support minimum -25°C ~ 125°C
• RoHS compliance: ROHS3 required

The substitute parts listed below meet all primary criteria and maintain functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

TDK CS65ZU2GA102MANKA is the primary substitute for the CS65ZU2GA102MYGKA. Both parts share identical electrical specifications (1000 pF, ±20%, 300VAC/440VAC, Z5U), mechanical dimensions (0.276" diameter, 7.50mm lead spacing), and safety ratings (X1, Y2). The CS65ZU2GA102MANKA offers extended operating temperature range (-55°C ~ 125°C) and includes AEC-Q200 automotive qualification, providing enhanced reliability for demanding applications. Inventory availability is significantly higher (4672 units).

TDK CS45-E2GA102M-GKA and CS45-E2GA102M-NKA are functionally equivalent substitutes with the following considerations: voltage rating is 440VAC only (no 300VAC rating), temperature coefficient is E instead of Z5U, and physical diameter is smaller (0.256" vs. 0.276"). These parts maintain all safety ratings and lead spacing compatibility. The CS45-E2GA102M-NKA offers superior inventory availability (2400 units).

Vishay VY2102M29Y5US63V7 is a cross-manufacturer substitute with equivalent electrical performance. Temperature coefficient is Y5U (E) with operating range -40°C ~ 125°C. Physical diameter is larger (0.295"), and voltage rating is 440VAC only. This part provides the highest inventory availability (44400 units) and represents an alternative sourcing option from a different manufacturer.

All substitute parts maintain ROHS3 compliance and active product status. Selection should be based on specific application requirements regarding voltage rating, temperature coefficient stability, physical space constraints, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can CS45-E2GA102M-GKA replace CS65ZU2GA102MYGKA in all applications?

A: CS45-E2GA102M-GKA is electrically compatible for applications operating at 440VAC. However, it is not suitable for circuits requiring 300VAC operation. The temperature coefficient difference (E vs. Z5U) may affect capacitance stability across the operating temperature range. Physical dimensions are smaller (0.256" vs. 0.276" diameter), which may affect PCB layout compatibility.

Q: What is the difference between Z5U and E temperature coefficients?

A: Both Z5U and E are temperature coefficients for ceramic capacitors. Z5U specifies capacitance change limits across -25°C ~ 125°C. E specifies tighter tolerances across -25°C ~ 125°C. The choice depends on application sensitivity to capacitance variation with temperature.

Q: Is the Vishay VY2102M29Y5US63V7 suitable for safety-rated applications?

A: Yes. The VY2102M29Y5US63V7 carries X1, Y2 safety ratings identical to the main part and all TDK substitutes, qualifying it for safety applications.

Q: Why does CS65ZU2GA102MANKA have a larger inventory than the main part?

A: CS65ZU2GA102MANKA is the automotive-qualified variant (AEC-Q200) with extended temperature range (-55°C ~ 125°C). Higher inventory reflects broader market demand for automotive and industrial applications requiring enhanced reliability specifications.

Q: Can I use VY2102M29Y5US63V7 if PCB space is limited?

A: No. The VY2102M29Y5US63V7 has a larger physical diameter (0.295" vs. 0.276"), which may exceed available PCB space. Verify physical dimensions against your PCB layout before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the environmental compliance status of the main part.

Q: Which substitute offers the best supply availability?

A: VY2102M29Y5US63V7 from Vishay offers the highest inventory (44400 units). For TDK-only sourcing, CS65ZU2GA102MANKA provides the best availability (4672 units).
