UPS2W4R7MHD1TO Equivalent & Substitute Parts

Part Overview

The UPS2W4R7MHD1TO is a 4.7 µF, 450 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 3000 hours at 105°C and is classified as Not For New Designs. Due to its obsolescence status and limited thermal lifetime, identifying equivalent substitute parts with improved specifications is necessary for design continuity and long-term reliability in applications requiring extended operational life.

Substitute Part Grouping Explanation

Substitution for the UPS2W4R7MHD1TO is determined by strict equivalence in the following electrical and mechanical parameters:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Configuration: Radial, Can through-hole mounting
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Operating Temperature Range: -25°C to 105°C (exact match required)
RoHS Compliance: ROHS3 Compliant

Substitute parts are grouped into two categories: Direct equivalents (identical specifications with improved thermal lifetime) and upgraded alternatives (same electrical parameters with enhanced performance characteristics or different packaging).

Engineering Selection Recommendations

Direct Equivalent (UPW2W4R7MHD1TO): This part maintains identical electrical and mechanical specifications to the UPS2W4R7MHD1TO while providing extended thermal lifetime of 7000 hours at 105°C compared to 3000 hours. The cut tape packaging matches the original specification. Both parts carry Not For New Designs status and ROHS3 compliance. This substitute is suitable for direct replacement in existing designs where component availability is the primary concern.

Upgraded Alternative (UPW2W4R7MHD): This part offers the same electrical performance and thermal lifetime as the direct equivalent but is supplied in bulk packaging rather than cut tape. The seated height is reduced to 0.787" (20.00 mm) compared to 0.866" (22.00 mm), providing a 0.079" (2.00 mm) reduction in vertical profile. This configuration may be advantageous in space-constrained applications. Both parts maintain ROHS3 compliance and identical ripple current ratings.

All substitute parts are manufactured by Nichicon and maintain full compatibility with the original part's electrical characteristics, operating temperature range, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can UPW2W4R7MHD1TO be used as a direct replacement for UPS2W4R7MHD1TO?

A: Yes. Both parts share identical capacitance (4.7 µF), voltage rating (450 V), tolerance (±20%), lead spacing (5.00 mm), and operating temperature range (-25°C to 105°C). The UPW2W4R7MHD1TO provides improved thermal lifetime (7000 hours versus 3000 hours at 105°C) while maintaining the same cut tape packaging and through-hole mounting configuration.

Q: What is the difference between UPW2W4R7MHD1TO and UPW2W4R7MHD?

A: Both parts are electrically identical with 7000-hour thermal lifetime at 105°C. The primary differences are packaging format (cut tape versus bulk) and seated height (0.866" versus 0.787"). The UPW2W4R7MHD offers a 2.00 mm reduction in vertical height, which may be beneficial in compact PCB layouts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The UPS2W4R7MHD1TO and both substitute parts (UPW2W4R7MHD1TO and UPW2W4R7MHD) are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates that the manufacturer is not recommending these parts for new product development. However, they remain available for replacement and maintenance applications. All three parts in this comparison carry this status.

Q: Do the substitute parts maintain the same ripple current ratings?

A: Yes. All three parts maintain identical ripple current specifications: 49 mA at 120 Hz and 78.4 mA at 10 kHz.

Q: Is the 2.00 mm height difference between UPW2W4R7MHD1TO and UPW2W4R7MHD significant for PCB design?

A: The height difference may be relevant in applications with strict vertical clearance constraints. The UPW2W4R7MHD provides a more compact profile at 0.787" (20.00 mm) seated height. Verify PCB layout requirements before selecting this variant.
