UPW1H151MPD Equivalent & Substitute Parts

Part Overview

The UPW1H151MPD is a 150 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. For new applications or ongoing production requiring equivalent functionality, substitute parts from active product lines are necessary to ensure long-term component availability and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the UPW1H151MPD is determined by the following mandatory parameters:

Capacitance: 150 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in height, impedance, ripple current ratings, and lifetime specifications do not preclude substitution, as these parameters remain within acceptable ranges for equivalent functionality in the same application context.

Engineering Selection Recommendations

Active Product Line Preference: EEU-FC1H151 and EEU-FC1H151B (Panasonic) are classified as Active products and are the preferred substitutes for new designs. Both parts carry AEC-Q200 automotive qualification, ensuring compliance with automotive reliability standards.

Nichicon Alternatives: UPM1H151MPD and UPS1H151MPD remain available from Nichicon inventory but are classified as "Not For New Designs." These parts are suitable only for legacy system maintenance or replacement applications where the original part number must be maintained.

Height Considerations: The UPW1H151MPD has the smallest seated height at 0.492" (12.50 mm). Substitute parts range from 0.551" to 0.866" in height. PCB layout verification is required if vertical clearance is constrained.

Compliance Status: All substitute parts are ROHS3 compliant. EEU-FC1H151 and EEU-FC1H151B carry REACH Unaffected status, while UPM1H151MPD is REACH Affected. UPS1H151MPD is REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1H151B replace UPW1H151MPD directly on the PCB?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (50 V), tolerance (±20%), lead spacing (0.197" / 5.00 mm), and case diameter (0.394" / 10.00 mm). The height difference (0.669" vs. 0.492") must be verified against PCB clearance constraints. The EEU-FC1H151B is available in Cut Tape packaging, while UPW1H151MPD is supplied in Bulk.

Q: What is the difference between EEU-FC1H151 and EEU-FC1H151B?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: EEU-FC1H151 is supplied in Bulk, while EEU-FC1H151B is supplied in Cut Tape (CT). Height specifications differ slightly (0.630" vs. 0.669"), reflecting manufacturing tolerance variations within the same product line.

Q: Why is UPW1H151MPD marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory remains available for legacy system support and replacement applications.

Q: Are all substitute parts automotive-qualified?

A: EEU-FC1H151, EEU-FC1H151B, and UPM1H151MPD carry AEC-Q200 automotive qualification. UPW1H151MPD and UPS1H151MPD do not carry automotive ratings and are designated for general-purpose applications.

Q: What is the impact of impedance differences between substitute parts?

A: Impedance values range from 100 mOhms (UPM1H151MPD) to 260 mOhms (UPS1H151MPD). Lower impedance generally indicates better high-frequency performance. Selection should be based on application ripple current requirements and frequency characteristics.

Q: Can UPS1H151MPD be used as a substitute despite lower lifetime rating?

A: UPS1H151MPD has a 2000 Hrs @ 105°C lifetime, compared to 5000 Hrs for UPW1H151MPD. Substitution is electrically valid but requires application-level assessment of thermal stress and expected operational life.
