SXR102M016ST Equivalent & Substitute Parts

Part Overview

The SXR102M016ST is a 1000 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating it is no longer in active production. The part operates across a temperature range of -40°C to 105°C and is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Due to its obsolete status, direct procurement of the SXR102M016ST may present supply chain challenges. Equivalent and substitute parts from active manufacturers provide viable alternatives that maintain electrical and mechanical compatibility while offering improved availability and, in many cases, enhanced performance characteristics such as extended operational lifetime and reduced ESR.

Substitute Part Grouping Explanation

Substitution of the SXR102M016ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Compatibility Criteria:

Capacitance: 1000 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 16 V (minimum; higher voltage ratings are acceptable as upgrades)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 5.00 mm (exact match required)
Diameter: 10.00 mm (exact match required)

Secondary Performance Parameters:

Operating Temperature Range: -40°C to 105°C (minimum requirement)
Ripple Current Capability: Must meet or exceed application requirements
ESR: Lower values indicate improved performance; higher values remain acceptable if within application tolerance
Lifetime @ 105°C: Extended lifetimes provide improved reliability; shorter lifetimes are acceptable if application requirements are met

Substitute parts are grouped into three categories:

Direct Equivalents (16 V Rated): Parts maintaining 16 V rating with identical mechanical dimensions and lead spacing. These provide drop-in replacement capability.
Upgrade Parts (25 V Rated): Parts with elevated voltage rating (25 V) while maintaining all mechanical parameters. These provide enhanced voltage margin and are suitable for applications where higher voltage headroom is beneficial.
Performance Variants: Parts with identical electrical ratings but differing height specifications, offering space optimization or alternative form factors within the same package family.

Engineering Selection Recommendations

For Direct Replacement (Mechanical and Electrical Compatibility):

The following parts provide direct substitution for the SXR102M016ST with active product status and ROHS3 compliance:

EKYB160ELL102MJ16S (Chemi-Con): Maintains 16 V rating, 1000 µF capacitance, and radial can package. Offers 10,000 hour lifetime at 105°C, representing a 2.5× improvement over the original part. Height of 17.50 mm provides space optimization compared to the original 30.00 mm specification.
16YXJ1000M10X16 (Rubycon): Active status with 10,000 hour lifetime at 105°C. Compact 17.50 mm height. Maintains all electrical and mechanical compatibility parameters.
EKZH160ELL102MJ16S (Chemi-Con): Active status with 6,000 hour lifetime at 105°C. Compact 17.50 mm height. Suitable for applications where extended lifetime is required beyond the original 4,000 hour specification.

Frequently Asked Questions (FAQ)

Q1: Can I use a 25 V rated capacitor (EKY-250ELL102MJ30S) in place of the 16 V SXR102M016ST?

A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The 25 V part will function correctly in a 16 V application. However, the increased height (31.50 mm vs. 30.00 mm original) must be verified against board layout constraints. The 25 V part is suitable only if physical space permits.

Q2: What is the significance of the "Not For New Designs" product status?

A: Parts designated "Not For New Designs" (16YXG1000MEFC10X20, UPW1C102MPD1TD) remain functionally equivalent but are in end-of-life phase. These parts are acceptable for replacement in existing equipment but should not be selected for new product development. Active-status alternatives are preferred for new designs.

Q3: Why do some substitute parts have different heights despite identical diameter and lead spacing?

A: Height variation reflects different internal construction and performance characteristics. Compact designs (17.50 mm) typically employ advanced internal geometry to achieve extended lifetime or improved ripple current handling within the same 10.00 mm diameter envelope. Height selection depends on available board space and application requirements.

Q4: How do I determine if a substitute part's ESR is acceptable for my application?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. Lower ESR values indicate improved performance. The original SXR102M016ST specifies 210 mOhm @ 120 Hz. Substitute parts with lower ESR values provide enhanced performance. If ESR data is not provided for a substitute part, consult the manufacturer's datasheet or contact the supplier for specific values.

Q5: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original part's environmental compliance status and meeting current regulatory requirements for electronic component manufacturing.

Q6: What is the difference between "Direct Equivalent" and "Upgrade" classifications?

A: Direct equivalents maintain the original 16 V rating and provide drop-in replacement capability. Upgrade parts (such as the 25 V EKY-250ELL102MJ30S) offer enhanced voltage margin but require verification of physical fit due to height differences. Selection depends on application voltage requirements and available board space.

Q7: Can I substitute a part with shorter lifetime (4,000 hours) for the original 4,000-hour specification?

A: Yes, if the application requirements are met. However, parts with extended lifetime (6,000 to 10,000 hours) are preferred for improved reliability and reduced maintenance risk, particularly in critical applications or equipment with long service life expectations.

Q8: What packaging options are available for substitute parts?

A: All substitute parts are supplied in Through Hole radial can package with 5.00 mm lead spacing, matching the original SXR102M016ST. Packaging format (Bulk or Cut Tape) varies by supplier but does not affect electrical or mechanical compatibility.
