Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SXR151M050ST are qualified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature: -40°C ~ 105°C (exact match required)
• Lifetime: 4000 Hrs @ 105°C (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Polarization: Polar (exact match required)

All identified substitute parts meet these criteria. Variations in ESR, ripple current ratings, impedance, and height (within mechanical envelope) do not disqualify substitution when all primary criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: EEU-FM1H151 (Panasonic) and EEU-FM1H151B (Panasonic) are recommended as primary substitutes. Both parts carry Active product status, ensuring long-term availability and supply chain stability. The EEU-FM1H151B is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes. The EEU-FM1H151 is supplied in Bulk packaging. Both Panasonic parts demonstrate ROHS3 compliance and REACH Unaffected status.

For Maintenance and Repair: EKZE500ELL151MJC5S (Chemi-Con) provides an alternative with Active product status and highest inventory availability (24,880 pcs). This part is suitable for field replacement applications.

For Legacy System Support: UHD1H151MPD (Nichicon) is classified as Not For New Designs but remains available for legacy system maintenance. This part carries REACH Affected status and should be evaluated against supply chain requirements for ongoing support applications.

Height Consideration: All substitute parts feature a maximum seated height of 0.551" (14.00mm), compared to the original SXR151M050ST at 0.787" (20.00mm). PCB layout verification is required to confirm mechanical clearance in existing designs.

Frequently Asked Questions (FAQ)

Q: Can EEU-FM1H151 and EEU-FM1H151B be used interchangeably with SXR151M050ST?

A: Yes. Both Panasonic parts meet all primary electrical and mechanical substitution criteria: 150 µF capacitance, 50 V rating, ±20% tolerance, 4000 Hrs @ 105°C lifetime, -40°C ~ 105°C operating range, 0.197" (5.00mm) lead spacing, 0.394" Dia (10.00mm) size, through-hole radial can package, and polar polarization. The primary difference is packaging format: EEU-FM1H151 is supplied in Bulk; EEU-FM1H151B is supplied in Cut Tape (CT).

Q: What is the significance of the height difference between SXR151M050ST and substitute parts?

A: The original SXR151M050ST has a maximum seated height of 0.787" (20.00mm). All qualified substitutes have a maximum seated height of 0.551" (14.00mm). This 6 mm reduction in height allows for improved PCB layout flexibility. However, designs with height-constrained clearance requirements must verify that the reduced height does not create unintended mechanical or thermal effects.

Q: Why is UHD1H151MPD classified as "Not For New Designs"?

A: UHD1H151MPD carries a "Not For New Designs" product status designation from Nichicon. This classification indicates that while the part remains available for existing applications and maintenance, it is not recommended for incorporation into new product designs. For new designs, EEU-FM1H151 or EEU-FM1H151B (both Active status) are preferred.

Q: Are there compliance differences between substitute parts?

A: All substitute parts are ROHS3 compliant. EEU-FM1H151 and EEU-FM1H151B are REACH Unaffected. UHD1H151MPD is REACH Affected. EKZE500ELL151MJC5S is REACH Unaffected. Design compliance requirements should be evaluated against specific regulatory frameworks applicable to the end application.

Q: What is the inventory status of substitute parts?

A: EEU-FM1H151 (Panasonic): 7,757 pcs. EEU-FM1H151B (Panasonic): 8,013 pcs. UHD1H151MPD (Nichicon): 2,533 pcs. EKZE500ELL151MJC5S (Chemi-Con): 24,880 pcs. Inventory levels support both production and maintenance requirements.
