Engineering Selection Recommendations

For Direct Replacement (Same Specifications): ECA-1CM102 (Panasonic Electronic Components, M-A series) provides direct functional equivalence with identical capacitance, tolerance, voltage rating, and operating temperature range. This part offers improved lifetime (2000 Hrs @ 85°C versus 1000 Hrs @ 85°C) while maintaining ROHS3 compliance. Physical dimensions differ slightly in diameter (0.394" versus 0.492") and height (0.669" versus 0.630"), requiring PCB layout verification.

For Enhanced Performance (Higher Voltage Rating): URS1E102MHD (Nichicon, URS series) and URZ1E102MHD (Nichicon, URZ series) both feature 25 V voltage ratings, providing increased safety margin in applications with voltage transients or design headroom requirements. Both maintain ROHS3 compliance and through-hole radial configuration with 5.00mm lead spacing. URS1E102MHD offers 2000 Hrs @ 85°C lifetime; URZ1E102MHD extends operating temperature to -55°C ~ 105°C with 1000 Hrs @ 105°C lifetime.

For Extended Temperature Range Applications: URZ1E102MHD and UPW1C102MPD both support -55°C ~ 105°C operating temperature range. URZ1E102MHD maintains 25 V rating; UPW1C102MPD maintains 16 V rating with extended 5000 Hrs @ 105°C lifetime. UPW1C102MPD carries "Not For New Designs" status and should be used only for legacy system maintenance.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the 108RSS016M.

Frequently Asked Questions (FAQ)

Q: Can URS1E102MHD or URZ1E102MHD be used as direct replacements for 108RSS016M?

A: Yes. Both parts maintain identical capacitance (1000 µF), tolerance (±20%), lead spacing (5.00mm), mounting type (through-hole), and package configuration (radial can). The 25 V voltage rating is compatible with 16 V applications, providing additional voltage margin. Physical dimensions differ slightly; verify PCB layout clearance for the 0.650" maximum height versus 0.630" original specification.

Q: What is the difference between URS1E102MHD and URZ1E102MHD?

A: Both are Nichicon 1000 µF, 25 V radial aluminum electrolytic capacitors with identical physical dimensions and lead spacing. URS1E102MHD operates -40°C ~ 85°C with 2000 Hrs @ 85°C lifetime. URZ1E102MHD operates -55°C ~ 105°C with 1000 Hrs @ 105°C lifetime. Select URZ1E102MHD for extended temperature range applications; select URS1E102MHD for standard temperature range with longer lifetime at 85°C.

Q: Is ECA-1CM102 a suitable substitute despite different physical dimensions?

A: ECA-1CM102 maintains all critical electrical specifications (1000 µF, ±20%, 16 V, polar, through-hole, 5.00mm lead spacing) and improves lifetime to 2000 Hrs @ 85°C. The diameter reduction from 0.492" to 0.394" and height increase from 0.630" to 0.669" require PCB layout verification to confirm clearance compatibility. Electrical performance is equivalent.

Q: Why is UPW1C102MPD marked "Not For New Designs"?

A: UPW1C102MPD carries obsolescence status indicating the manufacturer is phasing out this product line. While electrically and mechanically compatible with superior specifications (5000 Hrs @ 105°C, -55°C ~ 105°C), it should be used only for legacy system maintenance or repair. For new designs, select active-status alternatives: ECA-1CM102, URS1E102MHD, or URZ1E102MHD.

Q: What are the ripple current differences between the main part and substitutes?

A: Ripple current specifications vary by frequency and design. 108RSS016M specifies 655 mA @ 120 Hz and 917 mA @ 100 kHz. Substitute parts show different ripple current ratings reflecting internal design differences. Verify ripple current specifications against application requirements; higher ripple current capability indicates lower ESR and improved thermal performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (URS1E102MHD, URZ1E102MHD, ECA-1CM102, UPW1C102MPD) are ROHS3 compliant and REACH unaffected, matching the regulatory compliance of 108RSS016M.
