Substitute Part Grouping Explanation

Substitution of the SXR102M035ST is determined by strict equivalence in the following parameters:

Primary Matching Criteria:

• Capacitance value: 1000 µF (exact match required)
• Voltage rating: 35 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)
• Mounting type: Through Hole (exact match required)

Secondary Compatibility Factors:

• Operating temperature range: -40°C to 105°C (substitute must meet or exceed)
• RoHS compliance: ROHS3 Compliant (substitute must maintain compliance)

The substitute part 35ZLH1000MEFC12.5X20 from Rubycon meets all primary matching criteria and maintains full secondary compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

The 35ZLH1000MEFC12.5X20 from Rubycon is a direct electrical and mechanical equivalent to the obsolete SXR102M035ST. Both components share identical capacitance, voltage rating, tolerance, lead spacing, and mounting configuration, ensuring pin-compatible replacement in through-hole PCB applications.

The Rubycon substitute maintains ROHS3 compliance and operates across the same temperature range (-40°C to 105°C), satisfying regulatory and environmental requirements. The substitute demonstrates extended lifetime rating (10000 Hrs @ 105°C versus 4000 Hrs @ 105°C), indicating improved reliability characteristics.

Physical dimensions differ slightly: the Rubycon part measures 0.492" diameter (12.50 mm) and 0.866" height (22.00 mm), compared to the CDE original at 0.472" diameter (12.00 mm) and 1.181" height (30.00 mm). These dimensional variations remain within typical PCB layout tolerances for radial can capacitors and do not preclude direct substitution in standard applications.

The Rubycon part is currently in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete CDE component.

Frequently Asked Questions (FAQ)

Q: Can the 35ZLH1000MEFC12.5X20 be used as a direct replacement for the SXR102M035ST?

A: Yes. Both components are electrically and mechanically equivalent. They share identical capacitance (1000 µF), voltage rating (35 V), tolerance (±20%), lead spacing (0.197" / 5.00 mm), and mounting type (through-hole radial can). The Rubycon substitute is pin-compatible and suitable for direct PCB substitution.

Q: What are the physical dimension differences between these parts?

A: The SXR102M035ST measures 0.472" diameter × 1.181" height. The 35ZLH1000MEFC12.5X20 measures 0.492" diameter × 0.866" height. The substitute is slightly wider but shorter. Standard PCB layout tolerances for radial capacitors accommodate these variations without design modification.

Q: Are both parts RoHS compliant?

A: Yes. Both the SXR102M035ST and 35ZLH1000MEFC12.5X20 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the difference in lifetime ratings?

A: The SXR102M035ST is rated for 4000 hours at 105°C. The 35ZLH1000MEFC12.5X20 is rated for 10000 hours at 105°C. The Rubycon substitute offers extended operational life under elevated temperature conditions.

Q: Is the Rubycon part currently available?

A: Yes. The 35ZLH1000MEFC12.5X20 is in active production status with 2300 pieces confirmed in stock, ensuring reliable procurement compared to the obsolete CDE original.

Q: Do both parts operate across the same temperature range?

A: Yes. Both components operate from -40°C to 105°C, maintaining functional equivalence across the full specified temperature envelope.

Q: What is the lead spacing specification?

A: Both parts feature 0.197" (5.00 mm) lead spacing, ensuring compatibility with standard through-hole PCB footprints designed for radial aluminum electrolytic capacitors in this capacitance and voltage class.
