Substitute Part Grouping Explanation

Substitution eligibility for the UVR2V101MHA is determined by the following critical parameters:

Primary Compatibility Criteria:

Capacitance: 100 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage - Rated: 350 V minimum (equal or higher acceptable)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 0.295" (7.50mm) preferred for direct PCB compatibility
Physical Dimensions: Compatible envelope required

Substitute Categories:

Direct Equivalents maintain identical electrical and mechanical specifications within the same manufacturer series, differing only in packaging or product status designation.

Similar Substitutes share core electrical parameters and physical form factor but may have minor dimensional variations or different lead spacing that require PCB layout verification.

Upgrade Substitutes exceed the original specifications in voltage rating or operating temperature range, providing enhanced performance margins while maintaining mechanical compatibility.

Engineering Selection Recommendations

UVR2V101MHD (Direct Equivalent): This Nichicon part maintains identical electrical specifications and physical dimensions as the UVR2V101MHA. The primary distinction is product status designation (Not For New Designs versus Obsolete) and improved RoHS3 compliance. Lead spacing and form factor are identical, enabling direct PCB substitution without layout modification. Suitable for legacy system repairs where Nichicon UVR series continuity is preferred.

UVR2V101MRD6 (Similar Substitute): This Nichicon alternative shares core electrical parameters but features different physical dimensions: 0.866" diameter (22.00mm) versus 0.709" (18.00mm), and 1.260" height (32.00mm) versus 1.654" (42.00mm). Lead spacing differs at 0.394" (10.00mm) versus 0.295" (7.50mm). PCB layout verification is required before substitution. RoHS3 compliance is achieved.

MAL214261016E3 (Upgrade Substitute): This Vishay Beyschlag/Draloric/BC Components part provides enhanced specifications: 400 V rated voltage (versus 350 V) and 2500 Hrs @ 105°C lifetime (versus 2000 Hrs @ 85°C). Physical dimensions and lead spacing match the original part exactly, enabling direct PCB substitution. Operating temperature range extends to 105°C. Product status is Active with full RoHS3 compliance. Recommended for applications requiring improved performance margins.

Frequently Asked Questions (FAQ)

Q: Can UVR2V101MHD be used as a direct replacement for UVR2V101MHA?

A: Yes. Both parts share identical capacitance (100 µF), tolerance (±20%), voltage rating (350 V), lead spacing (0.295" / 7.50mm), and physical dimensions (0.709" diameter, 1.654" height). The primary difference is product status and RoHS compliance level. No PCB modification is required.

Q: What is the key difference between UVR2V101MRD6 and the original UVR2V101MHA?

A: UVR2V101MRD6 differs in physical dimensions and lead spacing. The diameter increases from 0.709" to 0.866", height decreases from 1.654" to 1.260", and lead spacing changes from 0.295" to 0.394". PCB layout verification is mandatory before substitution to confirm clearance and hole spacing compatibility.

Q: Why is MAL214261016E3 classified as an upgrade substitute?

A: MAL214261016E3 exceeds original specifications in two areas: voltage rating increases from 350 V to 400 V, and operating temperature range extends from -40°C ~ 85°C to -40°C ~ 105°C with 2500 Hrs lifetime at 105°C versus 2000 Hrs at 85°C. Physical dimensions and lead spacing remain identical, enabling direct substitution with enhanced performance margins.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed (UVR2V101MHD, UVR2V101MRD6, MAL214261016E3, SEK101M350ST, SK101M350ST) are RoHS3 compliant. The original UVR2V101MHA is RoHS non-compliant. Substitution addresses both obsolescence and regulatory compliance requirements.

Q: What is the operating temperature consideration when selecting between SEK101M350ST and SK101M350ST?

A: SEK101M350ST operates across -40°C ~ 105°C, while SK101M350ST operates across -25°C ~ 85°C. For applications requiring extended low-temperature operation below -25°C, SEK101M350ST is the appropriate selection. Both maintain identical lead spacing and capacitance specifications.

Q: Can UVR2V101MRD6 and SK101M350ST be used interchangeably?

A: No. While both are similar substitutes, they differ in critical dimensions. UVR2V101MRD6 has 0.866" diameter and 1.260" height with 0.394" lead spacing. SK101M350ST has 0.709" diameter and 1.496" height with 0.295" lead spacing. PCB layout compatibility cannot be assumed; physical verification is required.
