Electrical Equivalence Criteria:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Lifetime @ Temperature: 8000 Hrs @ 105°C (exact match required)
Polarization: Polar (exact match required)

Mechanical Equivalence Criteria:

Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)

Engineering Selection Recommendations

ELXY500ELL102ML30S is the primary substitute for the LXY50VB102M16X30LL. Both components are from the Chemi-Con LXY series and share identical electrical specifications. ELXY500ELL102ML30S carries Active product status and is ROHS3 compliant, making it suitable for new designs and long-term availability. The height difference of 0.059" (1.50 mm) must be verified against PCB layout constraints. This part is qualified to AEC-Q200 automotive standards, providing additional reliability assurance.

UPW1H102MHD is an alternative substitute from Nichicon. It meets all core electrical and mechanical equivalence criteria but carries a "Not For New Designs" status. The impedance is 4 mOhms higher (34 mOhms vs. 30 mOhms), and the seated height is 0.197" (5.00 mm) shorter than the original part. This component is ROHS3 compliant. Selection of UPW1H102MHD should be limited to legacy system support where design changes are not feasible.

For new designs and ongoing procurement, ELXY500ELL102ML30S is the recommended equivalent part.

Frequently Asked Questions (FAQ)

Q: Can ELXY500ELL102ML30S be used as a direct replacement for LXY50VB102M16X30LL?

A: ELXY500ELL102ML30S meets all electrical and mechanical equivalence criteria. The seated height is 1.240" (31.50 mm) compared to 1.181" (30.00 mm) for the original part. PCB layout must accommodate this 0.059" (1.50 mm) height difference. Both components use identical 0.295" (7.50 mm) lead spacing and 0.630" (16.00 mm) case diameter.

Q: What is the difference between ELXY500ELL102ML30S and UPW1H102MHD?

A: Both parts are electrically equivalent with 1000 µF capacitance, 50 V rating, and 8000-hour lifetime at 105°C. ELXY500ELL102ML30S is from Chemi-Con (same manufacturer as the original) with Active status and AEC-Q200 qualification. UPW1H102MHD is from Nichicon with "Not For New Designs" status. UPW1H102MHD has 4 mOhms higher impedance and is 0.197" (5.00 mm) shorter in seated height.

Q: Why is the original LXY50VB102M16X30LL classified as obsolete?

A: The LXY50VB102M16X30LL is marked obsolete by the manufacturer. ELXY500ELL102ML30S is the active equivalent from the same LXY series and should be used for new procurement and design activities.

Q: Are there RoHS compliance differences between these parts?

A: The original LXY50VB102M16X30LL is RoHS non-compliant. Both substitute parts, ELXY500ELL102ML30S and UPW1H102MHD, are ROHS3 compliant. This compliance upgrade should be verified against system-level RoHS requirements.

Q: What is the impact of impedance differences on circuit performance?

A: The original part and ELXY500ELL102ML30S both have 30 mOhms impedance. UPW1H102MHD has 34 mOhms impedance. For applications sensitive to ESR characteristics, particularly in high-frequency filtering or power supply circuits, the 4 mOhms difference may require circuit analysis to confirm functional equivalence.

Q: Can these parts be used interchangeably in automotive applications?

A: ELXY500ELL102ML30S carries AEC-Q200 qualification and is suitable for automotive use. UPW1H102MHD is ROHS3 compliant but does not carry automotive qualification. For automotive applications, ELXY500ELL102ML30S is the appropriate choice.
