Substitute Part Grouping Explanation

Substitution eligibility for the ESHSR-0100C0-002R7 is determined by the following critical parameters:

Capacitance: 100 F (direct match required)
Voltage Rating: 2.7 V (direct match required)
Mounting Type: Through Hole (direct match required)
Package Configuration: Radial, Can (compatible with snap-in or standard radial cans)
ESR: 10 mOhm baseline; substitutes with 12 mOhm or higher remain functionally compatible within design tolerances
Lifetime Rating: 1000 hours minimum at rated temperature
Lead Spacing: 0.394" (10.00 mm) preferred; 0.295" (7.50 mm) requires PCB layout verification

The substitute parts are grouped into two categories:

Direct Equivalent (BCAP0100 P270 S07): Identical capacitance, voltage, and lead spacing with improved ESR specification and active product status.

Similar Equivalent (HV1860-2R7107-R, HB1860-2R5117-R): Matching or near-matching capacitance and voltage with acceptable ESR variance and different lead spacing, requiring mechanical fit verification.

Engineering Selection Recommendations

BCAP0100 P270 S07 is the primary substitute for the ESHSR-0100C0-002R7. Both parts share identical capacitance (100 F), voltage rating (2.7 V), lead spacing (0.394" / 10.00 mm), and physical dimensions. The BCAP0100 P270 S07 maintains active product status and carries ROHS3 compliance certification. The ESR specification increases from 10 mOhm to 12 mOhm, which remains within acceptable design margins for most applications. The lifetime rating reduces from 1000 hours at 85°C to 1000 hours at 65°C, requiring thermal environment verification in high-temperature applications.

HV1860-2R7107-R (Eaton) is a secondary substitute matching the 100 F capacitance and 2.7 V voltage rating. This part is active and ROHS3 compliant. The lead spacing differs (0.295" / 7.50 mm versus 0.394" / 10.00 mm), and physical dimensions are smaller. PCB layout modification is required for mechanical fit. ESR is 12 mOhm at 100 Hz, and lifetime is 1000 hours at 65°C.

HB1860-2R5117-R (Eaton) is a tertiary option with 110 F capacitance and 2.5 V voltage rating. The voltage rating is 0.2 V lower than the original specification, which may impact circuit performance in voltage-sensitive applications. Lead spacing and physical dimensions differ significantly. ESR is 20 mOhm at 100 Hz, representing a 100% increase from the original 10 mOhm specification. This part is suitable only when circuit design tolerates the reduced voltage margin and higher ESR.

All substitute parts carry REACH Unaffected status and are classified under HTSUS 8532.29.0040.

Frequently Asked Questions (FAQ)

Q: Can BCAP0100 P270 S07 be used as a direct drop-in replacement for ESHSR-0100C0-002R7?

A: Yes, with thermal environment consideration. Both parts have identical lead spacing (0.394" / 10.00 mm), physical dimensions, capacitance (100 F), and voltage rating (2.7 V). The ESR increases from 10 mOhm to 12 mOhm. The primary difference is the lifetime rating: BCAP0100 P270 S07 is rated for 1000 hours at 65°C, while the original is rated at 85°C. If your application operates above 65°C, thermal derating analysis is required.

Q: What is the impact of increased ESR in substitute parts?

A: ESR affects charging/discharging speed and heat generation. BCAP0100 P270 S07 increases ESR from 10 mOhm to 12 mOhm (20% increase). HV1860-2R7107-R also specifies 12 mOhm at 100 Hz. HB1860-2R5117-R specifies 20 mOhm at 100 Hz (100% increase). For applications with high current transients or rapid charge/discharge cycles, higher ESR may introduce unacceptable voltage ripple or thermal stress. Circuit simulation is recommended for high-current applications.

Q: Are the Eaton parts (HV1860-2R7107-R and HB1860-2R5117-R) mechanically compatible?

A: Both Eaton parts have different lead spacing (0.295" / 7.50 mm versus 0.394" / 10.00 mm) and smaller physical dimensions. PCB layout modification is required. HV1860-2R7107-R is closer in size (0.709" diameter, 2.382" height) compared to HB1860-2R5117-R (0.728" diameter, 2.362" height). Verify mounting hole spacing and clearance before selection.

Q: What is the voltage derating impact of HB1860-2R5117-R?

A: HB1860-2R5117-R is rated at 2.5 V versus the original 2.7 V specification, a 0.2 V reduction (7.4% lower). This reduces the energy storage capacity and may affect circuit performance in applications with tight voltage margins. Use this part only when circuit design accommodates the lower voltage rating.

Q: Are all substitute parts RoHS compliant?

A: Yes. BCAP0100 P270 S07, HV1860-2R7107-R, and HB1860-2R5117-R are all ROHS3 compliant. The original ESHSR-0100C0-002R7 does not specify RoHS status.

Q: Which substitute offers the best thermal performance?

A: HB1860-2R5117-R has the highest operating temperature upper limit (70°C) and lowest lower limit (-25°C). However, it has the highest ESR (20 mOhm) and lowest voltage rating (2.5 V). BCAP0100 P270 S07 and HV1860-2R7107-R both support -40°C to 65°C operation with lower ESR (12 mOhm). For applications requiring -40°C operation, BCAP0100 P270 S07 and HV1860-2R7107-R are preferred.
