Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPS2W3R3MHD1TO is determined by the following critical parameters:

• Electrical Parameters: Capacitance (3.3 µF), tolerance (±20%), and rated voltage (450 V) must match exactly
• Mechanical Parameters: Lead spacing (5.00mm), case diameter (12.50mm), and mounting type (Through Hole, Radial) must be identical to ensure PCB compatibility
• Environmental Parameters: Operating temperature range (-25°C ~ 105°C) and polarization (Polar) must be maintained
• Compliance: RoHS3 compliance is required for all substitutes

The substitute parts UPJ2W3R3MHD1TO, UPM2W3R3MHD1TO, and UPW2W3R3MHD1TO meet all these criteria. These parts differ primarily in their lifetime ratings at 105°C (5000 Hrs or 7000 Hrs versus the original 3000 Hrs) and in specific application certifications, but maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are direct electrical and mechanical equivalents to the UPS2W3R3MHD1TO. Selection among these alternatives should be based on the following factors:

UPJ2W3R3MHD1TO: Offers improved lifetime (5000 Hrs @ 105°C) over the original UPS series while maintaining general-purpose application suitability. Height is marginally reduced (21.50mm vs 22.00mm), which may provide minor PCB layout advantages in space-constrained designs.

UPM2W3R3MHD1TO: Provides the same 5000 Hrs @ 105°C lifetime as the UPJ series but includes AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade reliability standards. Height matches the original specification at 22.00mm.

UPW2W3R3MHD1TO: Delivers the highest lifetime rating (7000 Hrs @ 105°C) among all substitutes, extending component operational life in high-temperature environments. Maintains original height specification and general-purpose application classification.

All substitutes maintain ROHS3 compliance and are available in production quantities. Selection should prioritize application requirements and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can UPJ2W3R3MHD1TO, UPM2W3R3MHD1TO, and UPW2W3R3MHD1TO be used interchangeably with UPS2W3R3MHD1TO?

A: Yes, these parts are direct substitutes. All maintain identical capacitance (3.3 µF), voltage rating (450 V), tolerance (±20%), lead spacing (5.00mm), case diameter (12.50mm), and mounting configuration (Through Hole, Radial). Electrical and mechanical compatibility is assured.

Q: What is the difference between the substitute parts?

A: The primary differences are lifetime ratings and application certifications. UPJ and UPW series offer extended lifetimes (5000 and 7000 Hrs @ 105°C respectively) compared to the original UPS series (3000 Hrs @ 105°C). UPM series includes AEC-Q200 automotive qualification. All other electrical and mechanical parameters remain identical.

Q: Does the height difference between UPJ2W3R3MHD1TO (21.50mm) and the original UPS2W3R3MHD1TO (22.00mm) affect compatibility?

A: The 0.50mm height reduction in the UPJ variant does not affect electrical compatibility. PCB layout and clearance requirements should be verified for the specific application, but the reduced height generally provides design flexibility without compromising performance.

Q: Which substitute should be selected for automotive applications?

A: UPM2W3R3MHD1TO is qualified to AEC-Q200 automotive standards and is the appropriate choice for automotive applications requiring this certification level.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all substitute parts (UPJ2W3R3MHD1TO, UPM2W3R3MHD1TO, and UPW2W3R3MHD1TO) are ROHS3 compliant, matching the compliance status of the original UPS2W3R3MHD1TO.

Q: What is the ripple current specification for each part?

A: UPS2W3R3MHD1TO and UPW2W3R3MHD1TO are rated for 41 mA @ 120 Hz. UPJ2W3R3MHD1TO and UPM2W3R3MHD1TO are rated for 48 mA @ 120 Hz. Both ratings are suitable for general-purpose applications within the specified operating parameters.
