Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

• Capacitance value: 4700 pF (exact match required)
• Voltage rating: 400VAC (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: Y5V (F) or Y5U (E) acceptable
• Operating temperature range: -30°C ~ 125°C (exact match required)
• Safety ratings: X1, Y2 (exact match required)
• Mounting configuration: Through Hole, Radial, Disc (exact match required)
• Lead spacing: 0.252" (6.40mm) (exact match required)

The substitute parts are grouped into two categories:

MFR Recommended Substitutes (Temperature Coefficient Y5U): Parts 30LVSD47-R and 30LVSD47BJ-R differ from the main part only in temperature coefficient (Y5U vs. Y5V) while maintaining all other electrical and mechanical specifications. These are active products with higher inventory availability.

Parametric Equivalent (Temperature Coefficient Y5V): Part 30LVSVD47-R maintains identical temperature coefficient to the main part and represents the closest parametric match, with the distinction of active product status.

Engineering Selection Recommendations

For Direct Replacement (Identical Footprint and Temperature Coefficient): Select 30LVSVD47-R. This part maintains the Y5V temperature coefficient of the original design and preserves the original physical dimensions (0.429" diameter, 0.555" height). Active product status ensures long-term availability and supply chain continuity.

For Alternative Substitution (Larger Footprint, Different Temperature Coefficient): Parts 30LVSD47-R and 30LVSD47BJ-R are acceptable substitutes where PCB layout permits accommodation of larger dimensions (0.488" diameter, 0.614" height). These parts employ Y5U temperature coefficient instead of Y5V. Both are active products with robust inventory levels (760 and 1059 units respectively). Selection between these two depends on packaging requirements (Bulk for both).

All substitute options maintain compliance with ROHS3 and REACH requirements, preserve safety ratings (X1, Y2), and operate within the specified temperature range (-30°C ~ 125°C).

Frequently Asked Questions (FAQ)

Q: Can 30LVSD47-R and 30LVSD47BJ-R be used interchangeably with 30LVSVD47QF-R? A: Both parts are electrically equivalent in capacitance, voltage rating, tolerance, and safety ratings. The primary difference is temperature coefficient (Y5U vs. Y5V) and physical dimensions. Substitution is valid where circuit design permits the larger package footprint and temperature coefficient variation.

Q: What is the difference between Y5V and Y5U temperature coefficients? A: Both Y5V (F) and Y5U (E) designations indicate Class II ceramic capacitors with -30°C to +125°C operating range. The distinction lies in capacitance change characteristics across temperature. Selection depends on circuit tolerance requirements for capacitance drift over the operating temperature range.

Q: Are there physical compatibility concerns when substituting 30LVSVD47-R for the obsolete 30LVSVD47QF-R? A: No. Part 30LVSVD47-R maintains identical physical dimensions (0.429" diameter, 0.555" height) and lead spacing (0.252") as the original, ensuring direct PCB compatibility.

Q: What are the physical constraints when using 30LVSD47-R or 30LVSD47BJ-R? A: These parts have larger dimensions (0.488" diameter, 0.614" height) compared to the original. PCB layout must accommodate the increased footprint. Lead spacing remains compatible at 0.252" (6.40mm).

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (30LVSD47-R, 30LVSD47BJ-R, and 30LVSVD47-R) are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original part.

Q: Which substitute offers the best supply chain continuity? A: Part 30LVSVD47-R is the recommended choice for supply continuity, as it is the closest parametric equivalent with active product status and identical physical dimensions. Parts 30LVSD47-R and 30LVSD47BJ-R offer higher inventory levels but require PCB layout verification due to larger package dimensions.
