Substitute Part Grouping Explanation

Substitute parts for the UHE1J152MHT are qualified based on the following electrical and mechanical parameters:

Capacitance: 1500 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 10,000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Package: Radial, Can (exact match required)
Mounting: Through Hole (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical specifications. Variations in secondary parameters such as ESR, ripple current ratings, impedance, and physical height do not disqualify substitution when primary parameters align.

Engineering Selection Recommendations

Primary Recommendation: EKYB630ELL152MMN3S or EKZN630ELL152MMN3S

Both Chemi-Con parts are actively manufactured and carry RoHS3 compliance certification. These parts are preferred for new designs and ongoing production due to their active product status and regulatory compliance. The reduced physical height (1.299" vs. 1.575") and lower impedance (18 mOhms vs. 36 mOhms) provide performance advantages in space-constrained applications and circuits requiring lower ESR characteristics.

Secondary Recommendation: UHE1J152MHD

This Nichicon part maintains identical electrical specifications and physical dimensions to the original UHE1J152MHT. However, its "Not For New Designs" status limits its suitability for new production. This part is appropriate only for legacy system maintenance where exact form-factor compatibility is critical.

Compliance Considerations: The original UHE1J152MHT is RoHS non-compliant. Both active Chemi-Con substitutes (EKYB630ELL152MMN3S and EKZN630ELL152MMN3S) are RoHS3 compliant, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can EKYB630ELL152MMN3S or EKZN630ELL152MMN3S be used as direct replacements for UHE1J152MHT?

A: Yes. Both parts meet all core electrical and mechanical specifications: 1500 µF capacitance, 63 V voltage rating, ±20% tolerance, 10,000 hour lifetime at 105°C, and identical lead spacing of 0.295" (7.50 mm). The reduced physical height does not affect electrical performance and may provide advantages in compact PCB layouts.

Q: What is the difference between EKYB630ELL152MMN3S and EKZN630ELL152MMN3S?

A: Both parts are manufactured by Chemi-Con and share identical electrical specifications and physical dimensions. They differ only in series designation (KYB vs. KZN) and represent different product lines within Chemi-Con's portfolio. Either part is suitable for substitution.

Q: Why is the impedance lower in the Chemi-Con substitutes?

A: The Chemi-Con parts (EKYB630ELL152MMN3S and EKZN630ELL152MMN3S) feature 18 mOhms impedance compared to 36 mOhms in the original Nichicon part. This lower impedance is a performance characteristic of the Chemi-Con design and does not affect substitution compatibility. Lower impedance generally reduces voltage ripple and heat generation in the capacitor.

Q: Is UHE1J152MHD suitable for new production?

A: UHE1J152MHD carries a "Not For New Designs" status and should be reserved for legacy system maintenance only. For new production, use EKYB630ELL152MMN3S or EKZN630ELL152MMN3S.

Q: Are there any RoHS compliance differences between substitute parts?

A: Yes. The original UHE1J152MHT is RoHS non-compliant. UHE1J152MHD is RoHS3 compliant. Both EKYB630ELL152MMN3S and EKZN630ELL152MMN3S are RoHS3 compliant. For applications requiring RoHS compliance, use any of the three compliant alternatives.

Q: Will the reduced height of Chemi-Con parts affect PCB layout?

A: The Chemi-Con substitutes are 0.276" (7.00 mm) shorter than the original part (1.299" vs. 1.575" seated height). This reduction provides additional clearance in space-constrained designs. No layout modifications are required; the parts are mechanically compatible with existing through-hole footprints.
