LMK105SD472JV-F Equivalent & Substitute Parts

Part Overview

The LMK105SD472JV-F is a 4700 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 10V operation in a 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 This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line.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 features low distortion characteristics and is suitable for general purpose applications requiring compact form factors and reliable performance across the -55°C to 125°C operating temperature range.

Identification of equivalent and substitute parts is necessary due to the product's discontinued status for new designs. Alternative components with compatible electrical and mechanical specifications ensure design continuity and supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMK105SD472JV-F is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 4700 pF
• Tolerance: ±5%
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant

Allowable Variation:

• Voltage Rating: Substitute parts may exceed the 10V rating of the main part, provided the higher voltage rating does not introduce incompatibility with the application circuit. A substitute with higher voltage rating maintains backward compatibility.

The identified substitute part KGM05AR71H472JH from KYOCERA AVX meets all mandatory parameters while providing an elevated voltage rating of 50V, making it suitable for applications where the original 10V specification is adequate.

Engineering Selection Recommendations

Primary Substitute: KGM05AR71H472JH

The KGM05AR71H472JH from KYOCERA AVX is the qualified substitute for the LMK105SD472JV-F. This recommendation is based on the following engineering criteria:

1. Electrical Compatibility: Both parts share identical capacitance (4700 pF) and tolerance (±5%) specifications. The substitute's 50V voltage rating exceeds the original 10V specification, ensuring compatibility in circuits designed for 10V operation.

2. Mechanical Compatibility: Identical package dimensions (0402 / 1005 Metric) and thickness (0.022" maximum) ensure direct board-level substitution without layout modifications.

3. Environmental Compliance: Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and manufacturing process requirements.

4. Product Status: The substitute is classified as Active, providing assured long-term availability and supply chain stability compared to the discontinued status of the original part.

5. Temperature Performance: Matching operating temperature range (-55°C ~ 125°C) ensures thermal performance equivalence across intended application environments.

Frequently Asked Questions (FAQ)

Q: Can the KGM05AR71H472JH directly replace the LMK105SD472JV-F in existing designs?

A: Yes. The substitute part maintains identical capacitance, tolerance, package dimensions, and operating temperature specifications. The higher 50V voltage rating is compatible with circuits designed for 10V operation.

Q: What is the significance of the X7R temperature coefficient on the substitute part?

A: X7R is a temperature coefficient classification for ceramic capacitors indicating capacitance variation of ±15% across the -55°C to 125°C operating range. This specification was not provided for the original part. The X7R rating ensures predictable capacitance stability across temperature extremes.

Q: Are there any board-level design changes required when substituting these parts?

A: No. Both parts use identical 0402 (1005 Metric) packaging with matching dimensions (0.039" L x 0.020" W x 0.022" max thickness). No PCB layout, footprint, or assembly process modifications are necessary.

Q: How does the higher voltage rating of the substitute affect circuit performance?

A: The 50V rating of the substitute provides increased voltage margin in the circuit. For applications operating at or below 10V, this higher rating does not negatively impact performance and may improve reliability by reducing electrical stress on the component.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the original part and substitute are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the moisture sensitivity implication of MSL 1 rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts can be stored and handled under standard industrial conditions without desiccant packaging or time-limited exposure windows.
