ESHSR-0010C0-002R7 Equivalent & Substitute Parts

Part Overview

The ESHSR-0010C0-002R7 is a 10 F supercapacitor manufactured by Maxwell Technologies, rated at 2.7 V with through-hole radial can packaging. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system design and procurement. The part features 26 mOhm equivalent series resistance and a rated lifetime of 1000 hours at 85°C. Substitute parts must maintain the same capacitance value, voltage rating, termination type, and mounting configuration to ensure functional compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ESHSR-0010C0-002R7 is determined by the following mandatory parameters:

Capacitance value of 10 F (exact match required)
Voltage rating of 2.7 V (exact match required)
Through-hole PC pin termination (exact match required)
Radial can package configuration (exact match required)
Lead spacing of 0.197" (5.00 mm) (exact match required)

Secondary parameters including ESR, lifetime rating, and operating temperature range may vary within acceptable engineering tolerances. Parts meeting all mandatory parameters are classified as direct substitutes. Parts with identical capacitance and voltage but differing secondary specifications are classified as similar substitutes and require application-level evaluation.

Engineering Selection Recommendations

BCAP0010 P270 S01 is the primary direct substitute for ESHSR-0010C0-002R7. Both parts are manufactured by Maxwell Technologies, share identical capacitance and voltage ratings, and maintain the same physical footprint and termination configuration. BCAP0010 P270 S01 carries active product status and ROHS3 compliance, making it the preferred choice for new designs and ongoing procurement.

HV1030-2R7106-R is a secondary direct substitute manufactured by Eaton - Electronics Division. This part maintains the 2.7 V voltage rating and 10 F capacitance with identical lead spacing and mounting type. The part is active and ROHS3 compliant. Physical dimensions differ slightly in height (1.240" versus 1.181"), which may require PCB layout verification.

HB1030-2R5106-R is a similar substitute with a reduced voltage rating of 2.5 V. This part is not recommended as a direct replacement due to the voltage differential. Use of this part requires circuit-level analysis to confirm that the lower voltage rating does not compromise system performance or safety margins.

Frequently Asked Questions (FAQ)

Q: Can BCAP0010 P270 S01 be used as a direct replacement for ESHSR-0010C0-002R7?

A: Yes. Both parts share identical capacitance (10 F), voltage rating (2.7 V), lead spacing (0.197"), termination type (PC Pins), and mounting configuration (through-hole radial can). Physical height differs by 0.059" (1.50 mm), which requires PCB layout verification but does not affect electrical compatibility.

Q: What is the significance of the ESR difference between the main part and substitutes?

A: ESR values range from 26 mOhm (main part) to 60 mOhm (HB1030-2R5106-R). Higher ESR increases power dissipation and reduces transient response capability. Applications requiring low ESR performance should prioritize BCAP0010 P270 S01 (30 mOhm) or HV1030-2R7106-R (34 mOhm).

Q: Is HB1030-2R5106-R suitable for applications originally designed for ESHSR-0010C0-002R7?

A: HB1030-2R5106-R operates at 2.5 V, which is 0.2 V lower than the original 2.7 V specification. This voltage reduction decreases energy storage capacity and may affect circuit performance. Use of this part requires application-specific analysis and is not recommended as a direct substitute without circuit redesign.

Q: What compliance certifications should be considered when selecting a substitute?

A: BCAP0010 P270 S01 and HV1030-2R7106-R both carry ROHS3 compliance, meeting current environmental and regulatory requirements. The original ESHSR-0010C0-002R7 does not specify RoHS status. For applications subject to RoHS requirements, active substitutes with explicit ROHS3 certification are required.

Q: Are there physical space constraints when substituting these parts?

A: Yes. The main part measures 1.181" (30.00 mm) in height, while BCAP0010 P270 S01 and HV1030-2R7106-R measure 1.240" (31.50 mm). HB1030-2R5106-R measures 0.413" (10.50 mm) in diameter versus 0.394" (10.00 mm) for other parts. PCB layout and enclosure clearances must be verified before substitution.
