Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMK063CG040CP-F are grouped based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Capacitance: 4 pF (exact match required)
• Tolerance: ±0.25pF (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Package / Case: 0201 (0603 Metric) (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Voltage Rating Considerations: Substitute parts are classified into two categories based on voltage rating:

1. Direct Equivalents (25V Rated): Parts with identical 25V voltage rating provide direct functional replacement without circuit modification.

2. Upgrade Substitutes (50V and 100V Rated): Parts with higher voltage ratings (50V or 100V) are electrically compatible and provide enhanced voltage margin. These upgrades maintain all other electrical and mechanical parameters while offering increased voltage headroom for circuit protection.

All substitute parts maintain REACH Unaffected status, EAR99 ECCN classification, and MSL 1 rating, ensuring regulatory and environmental compliance equivalence.

Engineering Selection Recommendations

Direct Equivalent Selection:

For applications requiring exact electrical and mechanical equivalence to the TMK063CG040CP-F, the following active parts are recommended:

• 02013A4R0CAT2A (KYOCERA AVX): Active product status with ROHS3 compliance. Identical 25V voltage rating and all electrical parameters. Packaged in Tape & Reel format with 801 units in stock.

• GRM0335C1E4R0CA01D (Murata Electronics): Active product status with ROHS3 compliance. Identical 25V voltage rating and all electrical parameters. Packaged in Tape & Reel format with 137,855 units in stock, providing superior availability.

• GRM0335C1E4R0CA01J (Murata Electronics): Active product status with ROHS3 compliance. Identical 25V voltage rating and all electrical parameters. Packaged in Tape & Reel format with 869 units in stock.

Upgrade Substitute Selection:

For applications where circuit design permits higher voltage ratings, upgrade substitutes provide enhanced voltage margin while maintaining all other electrical and mechanical specifications:

• GRM0335C1H4R0CA01D (Murata Electronics): 50V rated upgrade with active product status and ROHS3 compliance. 3,630 units in stock.

• GRM0335C1H4R0CA01J (Murata Electronics): 50V rated upgrade with active product status and ROHS3 compliance. 825 units in stock.

• GRM0335C2A4R0CA01D (Murata Electronics): 100V rated upgrade with active product status and ROHS3 compliance. 932 units in stock.

All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory equivalence with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V or 100V rated substitute in place of the 25V rated TMK063CG040CP-F?

A: Yes. Higher voltage-rated parts (50V and 100V) are electrically compatible substitutes. The capacitance, tolerance, temperature coefficient, package dimensions, and operating temperature range remain identical. The higher voltage rating provides additional circuit protection margin without affecting circuit performance at the original 25V operating point.

Q: What is the difference between the direct equivalents 02013A4R0CAT2A, GRM0335C1E4R0CA01D, and GRM0335C1E4R0CA01J?

A: All three parts are direct equivalents with identical electrical specifications (4 pF, ±0.25pF, 25V, C0G/NP0). The primary differences are manufacturer (KYOCERA AVX versus Murata Electronics) and inventory availability. GRM0335C1E4R0CA01D offers the highest stock level (137,855 units), making it the most readily available option.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original TMK063CG040CP-F does not specify RoHS status, but all active replacement options meet current RoHS3 requirements.

Q: Do the substitute parts have the same package dimensions as the original?

A: Yes. All substitute parts are housed in the 0201 (0603 Metric) surface mount package with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). They are directly compatible with existing PCB layouts and assembly processes.

Q: What is the moisture sensitivity level for the substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited) rating, identical to the original TMK063CG040CP-F. This indicates no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Can I mix different substitute parts in the same production run?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 25V rated options. However, mixing 25V and 50V/100V rated parts in the same design requires circuit-level verification to ensure voltage rating compatibility with your specific application requirements.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across the identical temperature range of -55°C to 125°C, matching the original TMK063CG040CP-F specifications.

Q: Are there any compliance or export restrictions on these substitute parts?

A: No. All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification, identical to the original part. No additional compliance documentation or export licensing is required.
