Substitute Part Grouping Explanation

Substitution eligibility for the UPS2E101MHD is determined by the following mandatory parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 250 V minimum (equal or higher voltage rating acceptable)
Tolerance: ±20% (standard tolerance maintained)
Polarization: Polar (required for electrolytic capacitors)
Mounting Type: Through Hole (mechanical compatibility)
Package Type: Radial, Can (form factor compatibility)
Operating Temperature: -40°C ~ 105°C (minimum requirement)
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Substitute parts are grouped into the following categories based on these parameters:

Direct Equivalents (Same Voltage, Improved Lifetime): Parts maintaining 250 V rating with enhanced operational lifetime, suitable for direct replacement in existing designs.

Upgraded Voltage Rating (350 V): Parts with higher voltage rating (UCY2V101MHD) providing additional design margin while maintaining identical capacitance and tolerance.

Alternative Form Factors: Parts with different lead spacing or dimensional characteristics (UCS2E101MND9, UCY2E101MHD6) that maintain electrical compatibility but require PCB layout verification.

Lower Lifetime Options: Parts with reduced operational lifetime (URZ2E101MHD at 1000 Hrs) for cost-sensitive applications where extended lifetime is not required.

Engineering Selection Recommendations

For New Designs: UCY2E101MHD or UCY2V101MHD are recommended. Both parts carry Active product status and provide extended operational lifetime (12000 Hrs @ 105°C). UCY2V101MHD offers additional voltage margin at 350 V. Both maintain ROHS3 compliance and are suitable for long-term supply chain stability.

For Direct Replacement (Same Form Factor): UPW2E101MHD provides an intermediate option with 8000 Hrs lifetime at 250 V, maintaining the same lead spacing (0.295") and similar dimensional profile as the UPS2E101MHD. However, this part is also obsolete.

For Space-Constrained Applications: UCY2E101MHD offers the smallest height (0.846") while maintaining 12000 Hrs lifetime and Active status, though it requires verification of lead spacing compatibility (0.295" maintained).

For Compact PCB Layouts: UCS2E101MND9 and UCY2E101MHD6 feature reduced lead spacing (0.197" and 0.197" respectively) and smaller diameters, suitable for high-density board designs. Both are Active products with extended lifetime specifications.

For Cost-Sensitive Applications: URZ2E101MHD is an Active product with reduced lifetime (1000 Hrs @ 105°C), suitable for applications where extended operational life is not required. Dimensional compatibility with the original part is maintained.

Parts to Avoid for New Designs: UPJ2E101MHD, UPM2E101MHD, UPW2E101MRD6, and UVY2E101MHD carry Obsolete or Not For New Designs status and should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can UCY2V101MHD replace UPS2E101MHD directly?

A: Yes, with verification. UCY2V101MHD maintains identical capacitance (100 µF), tolerance (±20%), and lead spacing (0.295"). The higher voltage rating (350 V vs. 250 V) is electrically compatible. However, the smaller diameter (0.630" vs. 0.709") and shorter height (1.299" vs. 1.476") require PCB layout verification to confirm mechanical fit.

Q: What is the difference between UCY2E101MHD and UCY2E101MHD6?

A: Both parts share the same electrical specifications (100 µF, 250 V, 12000 Hrs @ 105°C, Active status). The primary difference is lead spacing: UCY2E101MHD uses 0.295" spacing with 0.630" diameter, while UCY2E101MHD6 uses 0.197" spacing with 0.492" diameter. Selection depends on PCB hole pattern requirements.

Q: Is UCS2E101MND9 compatible with the original UPS2E101MHD footprint?

A: Electrically compatible, but mechanically different. UCS2E101MND9 has reduced lead spacing (0.197" vs. 0.295") and smaller diameter (0.394" vs. 0.709"), but significantly greater height (2.047" vs. 1.476"). PCB layout and clearance verification is mandatory before substitution.

Q: Why is URZ2E101MHD listed as a substitute despite lower lifetime?

A: URZ2E101MHD is an Active product with identical electrical parameters (100 µF, 250 V, ±20%) and compatible form factor (0.295" lead spacing, 0.709" diameter). The reduced lifetime (1000 Hrs vs. 3000 Hrs) makes it suitable only for applications where extended operational life is not a design requirement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the primary advantage of UCY2E101MHD over UPS2E101MHD?

A: UCY2E101MHD provides four times the operational lifetime (12000 Hrs vs. 3000 Hrs @ 105°C) while maintaining identical electrical specifications. Additionally, it carries Active product status, ensuring long-term availability and supply chain reliability.

Q: Can I use UPW2E101MHD as a long-term replacement?

A: UPW2E101MHD is not recommended for new designs despite improved lifetime (8000 Hrs). It carries Obsolete status, which may limit future availability. UCY2E101MHD is the preferred alternative with Active status and superior lifetime specifications.
