Equivalent & Substitute Parts for ECE-T2AP103FA

Part Overview

The ECE-T2AP103FA is a 10000 µF, 100 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the T-UP series. This radial, can-style snap-in capacitor with 4 leads is designed for general purpose applications requiring high capacitance at 100 V rating. The part is currently obsolete, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified based on strict electrical and mechanical parameter alignment:

Direct Substitutes (Electrical & Mechanical Equivalence):

• ALC70C103EH100 (KEMET)
• ALC70E103EH100 (KEMET)

These parts match all critical parameters: 10000 µF capacitance, 100 V voltage rating, ±20% tolerance, radial snap-in 4-lead package, 40.00mm diameter, through-hole mounting, and -40°C to 85°C operating temperature range. Lead spacing and package footprint are identical at 0.886" (22.50mm) and 1.575" diameter respectively.

Similar Substitute (Electrical & Mechanical Compatibility):

• 382LX103M100N062 (Cornell Dubilier Electronics)

This part maintains electrical equivalence (10000 µF, 100 V, ±20% tolerance) and mechanical compatibility (radial snap-in 4-lead, 40.00mm diameter, through-hole mounting, identical lead spacing). Height specification matches at 2.480" (63.00mm).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: ALC70C103EH100 and ALC70E103EH100 (KEMET)

Both KEMET parts are recommended as primary substitutes. They are active products with ROHS3 compliance and identical electrical ratings (10000 µF, 100 V, ±20% tolerance). The mechanical footprint is fully compatible with the original ECE-T2AP103FA, including identical lead spacing (0.886"), diameter (40.00mm), and package configuration (radial snap-in 4-lead). The height difference of 0.039" (1.00mm) is within typical PCB layout tolerances for through-hole components. Both parts offer extended lifetime specifications (18000 Hrs @ 85°C versus 3000 Hrs for the original), providing improved reliability in production designs.

Secondary Substitute: 382LX103M100N062 (Cornell Dubilier Electronics)

The CDE part is suitable where KEMET availability is constrained. It maintains full electrical equivalence and mechanical compatibility with identical dimensions and lead spacing. The lifetime specification matches the original part at 3000 Hrs @ 85°C. RoHS3 compliance is confirmed. This part is active and available in inventory.

All three substitute parts are through-hole mounted with identical lead spacing and diameter, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ALC70C103EH100 or ALC70E103EH100 be used as direct replacements for ECE-T2AP103FA?

A: Yes. Both KEMET parts are direct electrical and mechanical equivalents. They share identical capacitance (10000 µF), voltage rating (100 V), tolerance (±20%), package type (radial snap-in 4-lead), lead spacing (0.886"), and diameter (40.00mm). The height difference of 0.039" (1.00mm) does not affect through-hole PCB compatibility.

Q: What is the difference between ALC70C103EH100 and ALC70E103EH100?

A: Both parts are electrically and mechanically identical. They share the same capacitance, voltage rating, tolerance, ESR, ripple current ratings, dimensions, and operating temperature range. Selection between them is based on availability and supply chain considerations.

Q: Is the 382LX103M100N062 from Cornell Dubilier a suitable alternative?

A: Yes. The CDE part meets all electrical requirements (10000 µF, 100 V, ±20% tolerance) and maintains full mechanical compatibility with identical lead spacing, diameter, and height. It is an active product with RoHS3 compliance.

Q: Are there any height compatibility concerns with the KEMET substitutes?

A: The KEMET parts (ALC70C103EH100 and ALC70E103EH100) have a maximum seated height of 2.441" (62.00mm) compared to the original 2.480" (63.00mm). This 0.039" (1.00mm) difference is within standard PCB layout tolerances for through-hole components and does not require design modifications.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. ALC70C103EH100, ALC70E103EH100, and 382LX103M100N062 are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What are the ripple current ratings for the substitute parts?

A: KEMET parts (ALC70C103EH100 and ALC70E103EH100) are rated for 8.7 A @ 100 Hz (low frequency) and 10.35 A @ 10 kHz (high frequency). The original ECE-T2AP103FA is rated for 7.97 A @ 120 Hz and 9.166 A @ 10 kHz. The KEMET substitutes provide higher ripple current capacity.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All three substitute parts share identical lead spacing (0.886"), diameter (40.00mm), and through-hole mounting configuration. PCB layouts designed for the ECE-T2AP103FA require no modification to accommodate any of these substitutes.
