861141085021 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 861141085021 is a 1000 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in configuration, rated for 3000 hours at 105°C. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, lead time considerations, or specific performance characteristics within the allowed electrical and mechanical parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance (1000 µF), voltage rating (200 V), tolerance (±20%), polarization (Polar), lead spacing (0.394" / 10.00mm), diameter (1.181" / 30.00mm), mounting type (Through Hole), and package configuration (Radial, Can - Snap-In). All substitute parts maintain these core electrical and mechanical specifications. Variations in height, ripple current ratings, and lifetime characteristics are documented but do not disqualify substitution eligibility when the primary parameters align.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and comply with RoHS regulations. Selection between the main part (861141085021) and substitute parts should be based on availability, lead time, and specific application requirements within the electrical and mechanical parameter constraints.

The Rubycon 200MXG1000MEFCSN30X30 offers reduced height (1.260" vs. 1.457") while maintaining equivalent electrical specifications, suitable for space-constrained applications.

The Chemi-Con ELXS201VSN102MR30S provides extended lifetime rating (5000 hours vs. 3000 hours at 105°C), applicable to long-duration service environments.

The Chemi-Con EKMM201VSN102MR35S and Würth Elektronik 861141085021 share identical height and lifetime specifications, offering direct dimensional compatibility.

The Chinsan PK2D102MND3035 maintains full parameter equivalence with lower ripple current ratings, suitable for applications with reduced ripple current demands.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the 861141085021?

A: Yes, all listed substitute parts meet the core electrical and mechanical specifications: 1000 µF capacitance, 200 V voltage rating, ±20% tolerance, polar configuration, 10.00mm lead spacing, 30.00mm diameter, and through-hole snap-in mounting. Physical height variations exist and must be verified against PCB layout constraints.

Q: What is the significance of the height differences among substitute parts?

A: Height variations range from 1.260" (32.00mm) to 1.457" (37.00mm). PCB design clearance and component placement must accommodate the selected part's maximum seated height to prevent mechanical interference.

Q: How do ripple current ratings affect part selection?

A: Ripple current specifications indicate the maximum AC current the capacitor can withstand at specified frequencies. Applications with high ripple current demands should verify that the selected substitute part's ripple current rating meets or exceeds the circuit requirement.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are RoHS compliant. The main part and four substitutes carry ROHS3 certification; one substitute carries RoHS Compliant designation. Both certifications satisfy RoHS regulatory requirements.

Q: What is the difference between Direct Manufacturer Part Numbers and Parametric Equivalent Part Numbers?

A: Direct Manufacturer Part Numbers represent exact cross-references from the original part's substitution list. Parametric Equivalent Part Numbers meet all specified electrical and mechanical parameters but may originate from different sourcing chains or secondary cross-reference databases.
