Substitute Part Grouping Explanation

Substitution of the UVR2W010MPD is determined by strict equivalence in the following parameters:

Capacitance: 1 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Substitute parts are grouped into three categories based on additional performance characteristics:

Direct Equivalents maintain identical electrical and mechanical specifications, including lead spacing (0.138" / 4.60mm) and physical dimensions.

Upgrade Equivalents provide enhanced performance through extended lifetime ratings or higher operating temperature ranges while maintaining mechanical compatibility.

Similar Equivalents share core electrical specifications but may differ in lead spacing, physical dimensions, or ripple current ratings. These require verification of PCB layout compatibility before substitution.

Engineering Selection Recommendations

For Direct Replacement with Active Product Status:

ECA-2WM010 (Panasonic) and ECA-2WM010BJ (Panasonic) are the primary direct equivalents. Both maintain identical electrical specifications and lead spacing (0.138" / 4.60mm). ECA-2WM010BJ is supplied in Tape & Box packaging, while ECA-2WM010 is supplied in Bulk. Both are Active products with ROHS3 compliance.

For Enhanced Performance:

450BXC1MEFC8X11.5 (Rubycon) and ECA-2WHG010 (Panasonic) provide extended lifetime ratings. The Rubycon part offers 8000 Hrs @ 105°C, while the Panasonic ECA-2WHG010 offers 2000 Hrs @ 105°C. Both support higher operating temperatures (-25°C ~ 105°C) compared to the original specification (-25°C ~ 85°C). Both maintain lead spacing compatibility (0.138" / 4.60mm).

For Alternative Sourcing:

105CKS450M (Cornell Dubilier / Illinois Capacitor) and SK010M450ST (Cornell Dubilier Electronics) are parametric equivalents with identical electrical specifications and lead spacing. These parts are suitable when primary substitutes are unavailable.

For Non-Standard Lead Spacing Applications:

ECA-2WM010B (Panasonic) and ESMG451ELL1R0MJC5S (Chemi-Con) feature 0.197" (5.00mm) lead spacing. These parts are suitable only for PCB layouts designed for wider lead spacing and require physical layout verification before substitution.

All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original UVR2W010MPD.

Frequently Asked Questions (FAQ)

Q: Can ECA-2WM010 be used as a direct replacement for UVR2W010MPD?

A: Yes. ECA-2WM010 maintains identical capacitance (1 µF), voltage rating (450 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), operating temperature range (-25°C ~ 85°C), lead spacing (0.138" / 4.60mm), and package type (Radial, Can). It is an Active product with ROHS3 compliance.

Q: What is the difference between ECA-2WM010 and ECA-2WHG010?

A: Both parts share identical electrical specifications and lead spacing. The primary difference is operating temperature range and lifetime rating. ECA-2WHG010 supports -25°C ~ 105°C and is rated for 2000 Hrs @ 105°C, compared to ECA-2WM010 which supports -25°C ~ 85°C and is rated for 2000 Hrs @ 85°C. ECA-2WHG010 is suitable for applications requiring higher temperature operation.

Q: Can I use ECA-2WM010B as a substitute?

A: ECA-2WM010B is electrically equivalent but has different lead spacing (0.197" / 5.00mm versus 0.138" / 4.60mm). Substitution requires verification that the PCB layout accommodates the wider lead spacing. If the original PCB is designed for 0.138" spacing, ECA-2WM010B will not fit without modification.

Q: What is the difference between Bulk and Tape & Box packaging?

A: Bulk packaging (ECA-2WM010) is supplied loose in containers, suitable for high-volume manufacturing. Tape & Box packaging (ECA-2WM010BJ) is supplied on tape reels in boxes, suitable for automated assembly equipment. Electrical and mechanical specifications are identical; packaging choice depends on assembly process requirements.

Q: Is 450BXC1MEFC8X11.5 a suitable upgrade?

A: Yes, for applications requiring extended component lifetime or higher operating temperatures. The Rubycon part provides 8000 Hrs @ 105°C compared to the original 2000 Hrs @ 85°C. It maintains identical lead spacing (0.138" / 4.60mm) and electrical specifications. Height is slightly increased (0.531" versus 0.512"), requiring PCB layout verification.

Q: Can I substitute parts with different lead spacing?

A: No, unless the PCB layout is verified to accommodate the different spacing. Lead spacing determines hole positioning on the PCB. Mismatched spacing will result in mechanical incompatibility and assembly failure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original UVR2W010MPD.
