TMK105BJ104MP-F Equivalent & Substitute Parts

Part Overview

The TMK105BJ104MP-F is a 0.1 µF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V with X5R temperature coefficient in 0402 (1005 Metric) surface mount package. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. The part is designed for SMPS filtering applications and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Due to its obsolescence status, equivalent and upgraded substitute parts are necessary for ongoing production support, maintenance applications, and design continuity where this specific part number is currently specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK105BJ104MP-F is determined by strict equivalence across the following critical parameters:

Direct Equivalence Criteria:

• Capacitance: 0.1 µF (exact match required)
• Voltage Rating: 25V (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• RoHS Compliance: ROHS3 Compliant (compliance maintained)
• Moisture Sensitivity: MSL 1 (Unlimited) (exact match required)

Allowable Parameter Variations:

• Temperature Coefficient: X5R or X7R (both acceptable; X7R provides extended operating temperature range)
• Tolerance: ±20% or ±10% (tighter tolerance acceptable)
• Thickness: 0.022" (0.55mm) or 0.026" (0.65mm) (both within 0402 package specification)
• Operating Temperature: -55°C ~ 85°C (X5R) or -55°C ~ 125°C (X7R) (extended range acceptable)

Substitute parts are grouped into two categories: direct equivalents (matching X5R temperature coefficient) and upgraded alternatives (X7R temperature coefficient with enhanced temperature stability).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

TMK105BJ104MV-F is the direct functional equivalent to TMK105BJ104MP-F. Both parts maintain identical electrical specifications (0.1 µF, ±20%, 25V, X5R) and operating temperature range (-55°C ~ 85°C). This substitute is appropriate for applications requiring exact parameter matching and is suitable for direct replacement in existing designs. The reduced thickness (0.022" versus 0.026") provides improved PCB assembly compatibility without affecting electrical performance.

Upgraded Alternative Selection:

TMK105B7104KV-FR and TMK105B7104MV-FR are upgraded alternatives featuring X7R temperature coefficient, which extends the operating temperature range to -55°C ~ 125°C. These parts are suitable for applications requiring enhanced temperature stability or operation in elevated temperature environments. TMK105B7104KV-FR offers tighter tolerance (±10% versus ±20%), providing improved capacitance accuracy for precision filtering applications.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards. All parts are manufactured by Taiyo Yuden and share the same base product number (TMK105B), confirming design lineage and manufacturing consistency.

Frequently Asked Questions (FAQ)

Q: Can TMK105BJ104MV-F be used as a direct replacement for TMK105BJ104MP-F?

A: Yes. TMK105BJ104MV-F is a direct equivalent with identical electrical specifications (0.1 µF, ±20%, 25V, X5R, -55°C ~ 85°C). Both parts are pin-compatible in 0402 (1005 Metric) surface mount package and maintain equivalent performance in SMPS filtering applications.

Q: What is the difference between X5R and X7R temperature coefficients?

A: X5R temperature coefficient specifies capacitance change of ±15% across the operating temperature range of -55°C ~ 85°C. X7R temperature coefficient specifies capacitance change of ±15% across the extended operating temperature range of -55°C ~ 125°C. X7R provides superior temperature stability and wider operational temperature range.

Q: Are the upgraded parts (TMK105B7104KV-FR and TMK105B7104MV-FR) compatible with the original design?

A: Yes. Both upgraded parts maintain the same 0.1 µF capacitance, 25V voltage rating, and 0402 (1005 Metric) package as the original part. The X7R temperature coefficient and extended operating range provide enhanced performance without affecting circuit compatibility. The tighter tolerance in TMK105B7104KV-FR (±10%) improves capacitance accuracy.

Q: Does the thickness difference between substitute parts affect PCB assembly?

A: No. Both thickness specifications (0.022" and 0.026") are within the 0402 (1005 Metric) package standard. The reduced thickness of TMK105BJ104MV-F (0.022") and the upgraded parts (0.022") provides improved clearance for dense PCB layouts without compromising electrical performance or mechanical stability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TMK105BJ104MV-F, TMK105B7104KV-FR, TMK105B7104MV-FR) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, maintaining compliance with current environmental and manufacturing standards.

Q: What is the inventory status of substitute parts?

A: TMK105BJ104MV-F has 94,858 pieces in stock. TMK105B7104KV-FR has 158,100 pieces in stock. TMK105B7104MV-FR has 41,168 pieces in stock. All parts are available as new original components.
