Substitute Part Grouping Explanation

Substitute parts for the SXR102M010ST are categorized into three groups based on electrical and mechanical compatibility:

Direct Equivalents (Same Voltage Rating - 10V): Parts that maintain identical capacitance (1000 µF), voltage rating (10 V), tolerance (±20%), and physical form factor. These parts are pin-compatible and require no circuit modifications. Direct equivalents include EEU-FM1A102, EEU-FM1A102B, and EKZE100ELL102MJ16S.

Upgraded Alternatives (Higher Voltage Rating - 16V): Parts that increase the voltage rating from 10 V to 16 V while maintaining 1000 µF capacitance and ±20% tolerance. These parts are electrically superior and physically compatible with the original footprint, though height may vary slightly. Upgraded alternatives include EEU-EB1C102, EKZE160ELL102MJ20S, UHE1C102MPD, and UPW1C102MPD.

Similar Specification Parts (Same Voltage - 10V): Parts matching the original 10 V rating and 1000 µF capacitance with identical lead spacing and diameter, but with different height or performance characteristics. The part 10ZLH1000MEFC10X12.5 falls into this category.

All substitute parts maintain the following critical parameters with the SXR102M010ST:

Capacitance: 1000 µF
Tolerance: ±20%
Polarization: Polar
Package: Radial, Can
Mounting: Through Hole
Lead Spacing: 0.197" (5.00 mm)
Diameter: 0.394" (10.00 mm)
Operating Temperature: -40°C to 105°C
RoHS3 Compliance

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

Select from the direct equivalent group when the original 10 V rating is specified and adequate for the application. EEU-FM1A102B is the preferred choice due to active product status, highest inventory availability (13869 pieces), and cut tape packaging suitable for production environments. EEU-FM1A102 and EKZE100ELL102MJ16S are secondary options with active status and adequate stock levels.

For Voltage-Upgraded Applications:

When circuit design permits or requires higher voltage margin, select from the upgraded 16 V alternatives. EEU-EB1C102 offers the longest lifetime (10000 hours @ 105°C) and active product status, making it suitable for new designs. EKZE160ELL102MJ20S provides active status with high inventory (10502 pieces). UHE1C102MPD and UPW1C102MPD carry "Not For New Designs" status and should be used only for legacy system support or existing inventory management.

For Extended Lifetime Applications:

The 10ZLH1000MEFC10X12.5 from Rubycon provides 10000-hour lifetime at 105°C with exceptional inventory availability (399821 pieces) and maintains the original 10 V rating. This part is suitable when extended operational life is required and the reduced height (0.551" vs. 0.787") does not create mechanical constraints.

Compliance Considerations:

All recommended parts maintain ROHS3 compliance. Parts with "REACH Unaffected" or "REACH Affected" status should be verified against specific supply chain requirements. The SXR102M010ST is obsolete; therefore, transition to active-status alternatives is recommended for all new production.

Frequently Asked Questions (FAQ)

Q: Can EEU-FM1A102B directly replace SXR102M010ST without PCB modification?

A: Yes. EEU-FM1A102B maintains identical capacitance (1000 µF), voltage rating (10 V), tolerance (±20%), lead spacing (5.00 mm), and diameter (10.00 mm). The height is reduced from 0.787" to 0.689", which does not affect electrical function and may improve PCB layout clearance. No circuit modifications are required.

Q: What is the advantage of selecting a 16 V rated part instead of 10 V?

A: A 16 V rated capacitor provides higher voltage margin and typically offers improved reliability and longer operational lifetime. For example, EEU-EB1C102 (16 V) provides 10000-hour lifetime compared to 4000 hours for 10 V equivalents. Selection depends on circuit voltage specifications and reliability requirements.

Q: Why is 10ZLH1000MEFC10X12.5 shorter than the original part?

A: The 10ZLH1000MEFC10X12.5 achieves the same capacitance and voltage rating with reduced height (0.551" vs. 0.787") through optimized internal construction and superior dielectric materials. This is a design improvement, not a limitation. Verify that the reduced height does not conflict with PCB layout constraints.

Q: Are parts marked "Not For New Designs" suitable for production use?

A: Parts with "Not For New Designs" status (UHE1C102MPD, UPW1C102MPD) are suitable for legacy system support and replacement of existing assemblies. For new product development, select from parts with "Active" product status: EEU-FM1A102B, EKZE100ELL102MJ16S, 10ZLH1000MEFC10X12.5, EEU-EB1C102, or EKZE160ELL102MJ20S.

Q: What is the difference between EEU-FM1A102 and EEU-FM1A102B?

A: Both parts are electrically identical (1000 µF, 10 V, ±20%, 4000 Hrs @ 105°C). The primary difference is packaging: EEU-FM1A102 is supplied in bulk, while EEU-FM1A102B is supplied in cut tape (CT). For production environments, EEU-FM1A102B is preferred due to automated handling compatibility and higher available inventory (13869 vs. 979 pieces).

Q: Can I use a 16 V capacitor in a circuit designed for 10 V?

A: Yes. A higher voltage-rated capacitor is electrically compatible with lower voltage circuits. The capacitor will operate safely at voltages below its rating. This is a standard engineering practice for improving reliability margins.

Q: Which substitute part has the best long-term availability?

A: The 10ZLH1000MEFC10X12.5 from Rubycon has the highest inventory availability (399821 pieces) and active product status, indicating strong market supply. EEU-FM1A102B (13869 pieces) and EKZE160ELL102MJ20S (10502 pieces) are also well-stocked alternatives.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original SXR102M010ST specification. Verify REACH status (Unaffected or Affected) against specific supply chain requirements for your application region.
