Key Parameters

Substitute Part Grouping Explanation

Substitution of the UMK105CG090DW-F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 9 pF
• Tolerance: ±0.5pF
• Voltage Rating: 50V
• Temperature Coefficient: C0G/NP0
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Moisture Sensitivity Level: MSL 1

All substitute parts listed meet these parameters without exception. Substitutes are grouped into two categories: parametric equivalents from the same manufacturer (Taiyo Yuden) and direct manufacturer equivalents from alternative suppliers (KYOCERA AVX, TDK Corporation, Samsung Electro-Mechanics, Murata Electronics, and Cal-Chip Electronics).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: UMK105CG090DV-F

The UMK105CG090DV-F is the direct parametric equivalent from Taiyo Yuden with active product status. This part maintains identical electrical and mechanical specifications to the obsolete UMK105CG090DW-F while offering ROHS3 compliance and current manufacturing support. Selection of this part eliminates supplier qualification requirements and maintains design continuity with the original component manufacturer.

Secondary Recommendations: Active Manufacturer Alternatives

For applications requiring multi-source qualification or where Taiyo Yuden supply is constrained, the following active parts are suitable:

• C1005NP01H090D050BA (TDK Corporation): Offers extended operating temperature range to 150°C and the highest inventory availability (7987 pcs). Suitable for applications requiring enhanced thermal performance.

• GMC04CG9R0D50NT (Cal-Chip Electronics): Provides the largest inventory stock (40698 pcs) and ensures supply continuity for high-volume production requirements.

• GJM1555C1H9R0DB01D (Murata Electronics): Specified for RF, Microwave, and High Frequency applications with High Q and Low Loss characteristics. Select this part for signal integrity-critical designs.

• 04025A9R0DAT2A (KYOCERA AVX): Active status with standard operating temperature range. Suitable for general-purpose applications.

• CL05C090DB5NNNC (Samsung Electro-Mechanics): Active status with standard specifications. Suitable for general-purpose applications.

Not Recommended for New Designs: GRM1555C1H9R0DA01D

The GRM1555C1H9R0DA01D carries a "Not For New Designs" status despite high inventory availability. This designation indicates the manufacturer has discontinued active development and support for this part line. Use only for legacy system maintenance or repair of existing equipment.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete UMK105CG090DW-F with any of the listed parts?

A: Yes. All listed substitute parts match the mandatory electrical and mechanical parameters: 9 pF capacitance, ±0.5pF tolerance, 50V rating, C0G/NP0 temperature coefficient, 0402 package, and MSL 1 moisture sensitivity. Physical dimensions and mounting characteristics are identical across all parts.

Q: What is the difference between the main part and UMK105CG090DV-F?

A: The UMK105CG090DV-F is functionally identical to the UMK105CG090DW-F. The primary difference is product status: UMK105CG090DV-F is active with ROHS3 compliance, while UMK105CG090DW-F is obsolete. Both are manufactured by Taiyo Yuden and share the same electrical specifications and package form factor.

Q: Are there any operating temperature differences I should consider?

A: The C1005NP01H090D050BA (TDK) extends the upper operating temperature to 150°C compared to 125°C for most other parts. All other substitutes operate within the -55°C to 125°C range. Select the TDK part only if your application requires the extended high-temperature capability.

Q: What does "Not For New Designs" mean for the GRM1555C1H9R0DA01D?

A: This designation indicates that Murata Electronics has transitioned this part to legacy status and no longer recommends it for new product development. While the part remains available and functional, it should be used only for maintenance, repair, or support of existing equipment already using this component.

Q: Which substitute offers the best supply availability?

A: The GMC04CG9R0D50NT from Cal-Chip Electronics offers the highest inventory level at 40,698 pieces. The C1005NP01H090D050BA from TDK is the second-best option with 7,987 pieces available.

Q: Are all substitutes ROHS3 compliant?

A: All active and recommended substitute parts carry ROHS3 compliance certification. The original UMK105CG090DW-F does not specify RoHS status due to its obsolete classification.

Q: Can I use the GJM1555C1H9R0DB01D in general-purpose applications?

A: Yes. While the GJM1555C1H9R0DB01D is specified for RF, Microwave, and High Frequency applications with High Q and Low Loss characteristics, it meets all electrical and mechanical parameters for general-purpose use. However, for standard general-purpose applications, the GMC04CG9R0D50NT or C1005NP01H090D050BA may offer better cost efficiency.

Q: What is the difference between GJM1555C1H9R0DB01D and GJM1555C1H9R0DB01J?

A: Both parts are parametrically equivalent with identical electrical specifications and package form factor. The difference lies in packaging configuration and internal manufacturing codes. Both are active products suitable for RF and high-frequency applications.

Q: Do all substitutes have the same physical dimensions?

A: Yes. All substitute parts conform to the 0402 (1005 Metric) package standard with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum thickness of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts designed for the original part.

Q: Which substitute should I select for a new design?

A: For new designs, select from parts with "Active" product status: UMK105CG090DV-F, 04025A9R0DAT2A, C1005NP01H090D050BA, CL05C090DB5NNNC, GJM1555C1H9R0DB01D, GJM1555C1H9R0DB01J, or GMC04CG9R0D50NT. Avoid GRM1555C1H9R0DA01D due to its "Not For New Designs" status.
