Substitute Part Grouping Explanation

Substitution for the 1206J0630472KXR is determined by the following critical parameters:

• Capacitance Value: Must be 4700 pF
• Tolerance: Must be ±10%
• Temperature Coefficient: Must be X7R
• Package Format: Must be 1206 (3216 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• Voltage Rating: May be equal to or greater than 63V (higher voltage ratings provide additional design margin)
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The identified substitute part KGM31BR72A472KM from KYOCERA AVX meets all substitution criteria with an upgraded voltage rating of 100V, providing enhanced voltage margin while maintaining identical capacitance, tolerance, temperature coefficient, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1206J0630472KXR and KGM31BR72A472KM are active production parts with ROHS3 compliance and MSL 1 rating, making them suitable for general-purpose applications. The substitute part KGM31BR72A472KM offers a higher voltage rating of 100V compared to the 63V rating of the main part, providing additional voltage margin in circuit designs. The substitute part also features a reduced maximum thickness of 0.037" (0.94mm) versus 0.063" (1.60mm), which may provide space advantages in compact PCB layouts. Both parts maintain identical electrical characteristics in capacitance, tolerance, and temperature coefficient, ensuring functional equivalence in applications operating within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can KGM31BR72A472KM be used as a direct replacement for 1206J0630472KXR?

A: Yes. Both parts share identical capacitance (4700 pF), tolerance (±10%), temperature coefficient (X7R), package format (1206), and operating temperature range (-55°C ~ 125°C). The substitute part has a higher voltage rating (100V vs. 63V) and reduced thickness, making it electrically and mechanically compatible.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The 100V rating on KGM31BR72A472KM provides additional voltage margin compared to the 63V rating of the main part. This allows the substitute to operate safely in circuits with higher voltage stress, though it will function identically in applications designed for 63V operation.

Q: Are there any physical installation differences between these parts?

A: Both parts use the same 1206 (3216 Metric) package footprint and surface-mount configuration. The substitute part has a lower maximum thickness (0.94mm vs. 1.60mm), which may provide benefits in space-constrained designs but does not affect PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1206J0630472KXR and KGM31BR72A472KM are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), meeting identical environmental and regulatory requirements.

Q: What determines whether a part can substitute for the 1206J0630472KXR?

A: Substitution requires matching capacitance value (4700 pF), tolerance (±10%), temperature coefficient (X7R), package format (1206), mounting type (surface mount MLCC), and operating temperature range (-55°C ~ 125°C). Voltage rating may be equal to or higher than 63V. Compliance certifications must remain equivalent.
