Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 4.7 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.098" (2.50 mm) (exact match required)
Case Diameter: 0.248" (6.30 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Secondary Substitution Criteria (Voltage Rating): Substitute parts may have equal or higher voltage ratings than the original 160 V specification. Higher voltage ratings provide design margin and are electrically compatible in circuits designed for 160 V operation.

Tertiary Substitution Criteria (Lifetime & Temperature): Substitute parts may have equal or extended lifetime ratings and operating temperature ranges. Extended specifications provide improved reliability margins.

Substitute parts are grouped into two categories:

Upgrade Substitutes (200 V or 250 V rated): Parts with voltage ratings of 200 V or 250 V that maintain all other mechanical and electrical parameters. These provide enhanced voltage margin over the original 160 V specification.

Parametric Equivalent (160 V rated): Parts with identical voltage rating to the original specification, providing direct functional equivalence.

Engineering Selection Recommendations

For Active Production Designs:

Select from Rubycon LEX or LLE series parts (200LEX4.7MEFC6.3X11, 200LEX4R7MEFC6.3X11, 200LLE4R7MEFC6.3X11, 200LLE4R7MEFCMZ6.3X11) or Chemi-Con KMQ series parts (EKMQ201ELL4R7MF11D, EKMQ251ELL4R7MF11D). These parts carry Active product status and ROHS3 compliance, ensuring long-term supply availability and regulatory conformance.

The Rubycon LLE series (200LLE4R7MEFC6.3X11, 200LLE4R7MEFCMZ6.3X11) offers extended lifetime ratings of 12000 hours at 105°C, providing superior reliability margins compared to the original 1000-hour specification.

For Height-Constrained Applications:

Parts with 0.492" (12.50 mm) seated height match the original dimension: 200PX4.7MEFC6.3X11, EKMQ201ELL4R7MF11D, EKMQ251ELL4R7MF11D, UVY2D4R7MED, UVY2E4R7MED, and UVZ2C4R7MED. Parts with 0.512" (13.00 mm) height require PCB layout verification.

For Voltage Margin Requirements:

Parts rated at 200 V (Rubycon LEX, LLE, PX series and Chemi-Con EKMQ201) or 250 V (Chemi-Con EKMQ251, Nichicon UVY2E) provide enhanced voltage headroom over the original 160 V specification.

Parametric Equivalent:

UVZ2C4R7MED provides direct parametric equivalence with identical 160 V voltage rating and 1000-hour lifetime at 105°C. However, this part carries Obsolete status.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V or 250 V rated capacitor in place of the 160 V original?

A: Yes. Higher voltage ratings are electrically compatible in circuits designed for 160 V operation. The capacitor will function correctly and provide additional voltage margin. No circuit modifications are required.

Q: What is the significance of the height difference between 0.492" and 0.512"?

A: The 0.020" (0.50 mm) height difference may affect PCB layout clearance in space-constrained designs. Verify available vertical clearance before selecting parts with 0.512" height. Parts with matching 0.492" height include 200PX4.7MEFC6.3X11, EKMQ201ELL4R7MF11D, EKMQ251ELL4R7MF11D, and the Nichicon UVY series.

Q: Why do some substitute parts have extended lifetime ratings?

A: Extended lifetime ratings (4000 hours at 125°C for Rubycon LEX series, 12000 hours at 105°C for Rubycon LLE series) reflect improved capacitor design and materials. These parts provide enhanced reliability margins and longer operational life under thermal stress compared to the original 1000-hour specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original part's regulatory status.

Q: What is the difference between Rubycon LEX and LLE series?

A: Both series maintain 4.7 µF capacitance and ±20% tolerance with identical mechanical dimensions. The LEX series provides 4000-hour lifetime at 125°C operating temperature. The LLE series provides 12000-hour lifetime at 105°C operating temperature. Selection depends on thermal environment and required reliability margin.

Q: Can I substitute an Obsolete-status part for the original?

A: Obsolete parts (UVY2D4R7MED, UVY2E4R7MED, UVZ2C4R7MED) are electrically and mechanically compatible but carry Obsolete product status, indicating discontinued manufacturing. For new designs and ongoing production, select Active-status alternatives to ensure supply continuity.

Q: What does "Parametric Equivalent" mean?

A: UVZ2C4R7MED is classified as a parametric equivalent because it matches the original part's voltage rating (160 V), capacitance (4.7 µF), tolerance (±20%), lifetime (1000 Hrs @ 105°C), and all mechanical dimensions. It provides direct functional replacement with identical electrical performance.
