Key Parameters

Substitute Part Grouping Explanation

Substitution of the PAS1016LS2R5205 is determined by compatibility across the following critical parameters: capacitance value, voltage rating, ESR characteristics, mounting type, package style, and termination method. The identified substitute parts maintain through-hole radial can packaging with PC pin termination, ensuring mechanical and electrical compatibility with existing PCB layouts.

Two substitute parts are identified:

LP10202R7505 provides higher capacitance (5 F) at equivalent voltage rating (2.7 V) with improved ESR performance (60 mOhm @ 1kHz). This part accommodates applications requiring increased energy storage capacity while maintaining compatible form factor and lead spacing.

LP08152R7245 offers comparable capacitance (2.4 F) at slightly elevated voltage rating (2.7 V) with different ESR characteristics (120 mOhm @ 1kHz). This part provides a closer capacitance match to the original specification with enhanced operating temperature range.

Both substitute parts are manufactured by Taiyo Yuden and classified as obsolete, with RoHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

LP10202R7505 is suitable for applications where increased capacitance (5 F) is acceptable and beneficial. This part maintains identical lead spacing (5.00 mm) and diameter (10.00 mm) as the original PAS1016LS2R5205, ensuring direct PCB compatibility. The higher voltage rating (2.7 V) and improved ESR (60 mOhm @ 1kHz) provide enhanced performance characteristics. Extended operating temperature range (-40°C ~ 85°C) and ROHS3 compliance certification support broader deployment scenarios. Height increase to 22.00 mm requires verification of available vertical clearance in the target application.

LP08152R7245 provides the closest capacitance match (2.4 F) to the original specification with minimal deviation. This part features ROHS3 compliance and extended operating temperature range (-40°C ~ 85°C). However, reduced lead spacing (3.50 mm) and smaller diameter (8.00 mm) necessitate PCB layout modification. This part is appropriate for space-constrained applications where the original footprint cannot be accommodated.

Selection between substitute parts depends on PCB layout constraints, capacitance requirements, and thermal operating conditions. Both parts maintain through-hole radial can packaging with PC pin termination and carry identical moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can LP10202R7505 directly replace PAS1016LS2R5205 on existing PCBs?

A: LP10202R7505 maintains identical lead spacing (5.00 mm) and diameter (10.00 mm), enabling direct PCB mounting. Vertical clearance must accommodate the increased height of 22.00 mm compared to the original 18.00 mm. Electrical performance differs due to higher capacitance (5 F vs. 2 F) and ESR characteristics (60 mOhm @ 1kHz vs. 50 mOhm).

Q: What are the key differences between LP10202R7505 and LP08152R7245?

A: LP10202R7505 offers 5 F capacitance with 60 mOhm ESR and maintains the original lead spacing and diameter. LP08152R7245 provides 2.4 F capacitance with 120 mOhm ESR and requires smaller lead spacing (3.50 mm) and diameter (8.00 mm). Both parts operate across -40°C ~ 85°C temperature range, exceeding the original -25°C ~ 70°C specification.

Q: Does LP08152R7245 require PCB redesign?

A: Yes. LP08152R7245 features reduced lead spacing (3.50 mm vs. 5.00 mm) and smaller diameter (8.00 mm vs. 10.00 mm), necessitating PCB layout modification. Height is comparable to the original part at 17.00 mm.

Q: Are both substitute parts RoHS compliant?

A: Both LP10202R7505 and LP08152R7245 carry ROHS3 compliance certification. The original PAS1016LS2R5205 does not specify RoHS status.

Q: What is the impact of higher ESR in LP08152R7245?

A: LP08152R7245 exhibits 120 mOhm ESR @ 1kHz, compared to 50 mOhm in the original part and 60 mOhm in LP10202R7505. Higher ESR increases resistive losses and heat generation during charge/discharge cycles. Application-specific performance analysis is required to determine acceptability.

Q: Can these parts operate at temperatures below -25°C?

A: LP10202R7505 and LP08152R7245 both support operating temperatures to -40°C, extending the original specification of -25°C. Upper temperature limits are 85°C for both substitutes, compared to 70°C for the original part.

Q: What is the voltage rating difference between the original and substitute parts?

A: PAS1016LS2R5205 is rated at 2.5 V. Both substitute parts are rated at 2.7 V. Applications designed for 2.5 V operation remain compatible with the higher-rated substitutes. Circuits requiring exactly 2.5 V maximum must evaluate the impact of the 0.2 V increase.
