Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the F930J157MCC are qualified based on the following criteria:

Primary Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

Allowable Variations:

• Voltage Rating: Equal to or greater than 6.3 V
• Tolerance: ±10% or ±20%
• ESR: Equal to or less than 700 mOhm @ 100kHz
• Lifetime @ Temp.: 2000 Hrs @ 125°C or unspecified

Three substitute parts meet these criteria across manufacturers KEMET and Vishay Sprague, each offering different tolerance and voltage specifications while maintaining identical mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

293D157X96R3C2TE3 (Vishay Sprague TANTAMOUNT™ Series) This substitute provides tighter tolerance (±10%) at the same 6.3 V rating and identical ESR specification. It is ROHS3 compliant and suitable for applications requiring improved capacitance accuracy. Lifetime data is not specified; verify against application requirements if extended temperature operation is critical.

T491C157M006AT (KEMET T491 Series) This substitute matches the original ±20% tolerance and 6.3 V rating with identical thermal specifications (2000 Hrs @ 125°C). ESR is higher at 1.2 Ohm compared to 700 mOhm; this is acceptable for general-purpose applications but may impact performance in high-frequency or low-impedance circuits. ROHS3 compliant.

T494C157K010AT (KEMET T494 Series) This substitute offers higher voltage rating (10 V) with tighter tolerance (±10%) and identical ESR (700 mOhm). It provides design margin for voltage stress and improved capacitance stability. ROHS3 compliant with 2000 Hrs @ 125°C lifetime rating. Suitable for applications where voltage headroom and tolerance precision are beneficial.

All substitutes are active production parts with full RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original component's environmental qualifications.

Frequently Asked Questions (FAQ)

Q: Can T491C157M006AT be used as a direct replacement for F930J157MCC? A: Yes. Both parts share identical capacitance (150 µF), voltage rating (6.3 V), tolerance (±20%), package (2312), and operating temperature range (-55°C to 125°C). The higher ESR (1.2 Ohm vs. 700 mOhm) is acceptable for general-purpose applications but may affect performance in circuits sensitive to impedance.

Q: What is the advantage of using T494C157K010AT over the original F930J157MCC? A: T494C157K010AT provides two benefits: higher voltage rating (10 V vs. 6.3 V) for increased design margin, and tighter tolerance (±10% vs. ±20%) for improved capacitance accuracy. ESR remains identical at 700 mOhm. Physical dimensions and mounting are unchanged.

Q: Is 293D157X96R3C2TE3 compatible with the original circuit design? A: Yes. This part is mechanically and electrically compatible. It matches all critical parameters: capacitance, voltage, package, and operating temperature. The ±10% tolerance is tighter than the original ±20%, providing better capacitance stability. Lifetime data is not specified; confirm this meets application requirements if long-term reliability at elevated temperature is critical.

Q: Do all substitute parts have the same physical dimensions? A: Yes. All substitute parts use the 2312 (6032 Metric) package with identical dimensions: 0.236" L × 0.126" W (6.00 mm × 3.20 mm) and maximum seated height of 0.110" (2.80 mm). They are direct mechanical replacements on PCBs designed for the F930J157MCC.

Q: Are there any compliance differences between the original and substitute parts? A: No. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical across all parts.

Q: Which substitute should I choose for high-frequency applications? A: For circuits operating at high frequencies where ESR is critical, select either 293D157X96R3C2TE3 or T494C157K010AT, both with 700 mOhm ESR. Avoid T491C157M006AT in high-frequency applications due to its higher 1.2 Ohm ESR.
