SXR471M016ST Equivalent & Substitute Parts

Part Overview

The SXR471M016ST is a 470 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in radial, can package configuration. This component is classified as obsolete, indicating discontinued production and limited availability for new procurement. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 4000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Identification of equivalent and substitute parts is necessary due to the obsolete status of the SXR471M016ST. Active production alternatives from current manufacturers ensure design continuity, improved availability, and compliance with modern supply chain requirements.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameters:

Direct Equivalents (16 V Rating): Parts maintaining the original 16 V voltage rating with identical capacitance (470 µF), tolerance (±20%), and physical form factor (radial, can, 5.00 mm lead spacing, through-hole mounting). These parts are interchangeable without circuit modification.

Upgrade Alternatives (25 V Rating): Parts with elevated voltage rating (25 V) while maintaining all other critical parameters. These provide enhanced voltage margin and are suitable for applications where the original 16 V specification permits higher-rated components.

Substitution logic is determined by the following parameters:

Capacitance value (470 µF)
Tolerance specification (±20%)
Voltage rating (16 V minimum for direct substitution; 25 V for upgrades)
Package configuration (radial, can)
Lead spacing (5.00 mm)
Mounting method (through-hole)
Operating temperature range (-40°C to 105°C)
RoHS3 compliance status

Engineering Selection Recommendations

Direct Substitution (16 V Rating):

EEU-FM1C471B (Panasonic) and EEU-FM1C471 (Panasonic) are primary direct equivalents. Both maintain active product status with full RoHS3 compliance. The EEU-FM1C471B variant in cut-tape packaging offers 3491 units in stock inventory. These parts feature reduced height (14.00 mm versus 16.00 mm original), which may provide PCB layout advantages in space-constrained applications.

EKY-160ELL471MJC5S (Chemi-Con) provides extended lifetime specification (7000 hours at 105°C versus 4000 hours), offering enhanced reliability margin while maintaining active production status and full compliance.

EKZE160ELL471MJC5S (Chemi-Con) delivers balanced performance with active status and substantial inventory availability (1059 units).

UHE1C471MPD6 (Nichicon) is classified as "Not For New Designs" and carries REACH-affected status, limiting suitability for new applications despite adequate technical specifications.

Upgrade Substitution (25 V Rating):

EKZE250ELL471MJ16S (Chemi-Con) is the recommended upgrade option, offering active product status, highest inventory availability (61340 units), and 4000-hour lifetime specification matching the original part. The 25 V rating provides voltage margin for applications where circuit design permits higher-rated components.

EEU-EB1E471 (Panasonic) provides extended 10000-hour lifetime at 105°C with active status and full compliance, suitable for demanding reliability requirements.

EKY-250ELL471MJ16S (Chemi-Con) offers 7000-hour lifetime with active status.

UHD1E471MPD6 and UHE1E471MPD6 (Nichicon) carry "Not For New Designs" designation and REACH-affected status, limiting applicability to new designs.

Height Considerations:

Direct 16 V equivalents feature reduced height (14.00 mm) compared to the original 16.00 mm specification. Upgrade 25 V alternatives feature increased height (16.00-17.50 mm). PCB layout verification is required when height variation exceeds design tolerances.

Frequently Asked Questions (FAQ)

Q: Can EEU-FM1C471B directly replace SXR471M016ST without circuit modification?

A: Yes. EEU-FM1C471B maintains identical capacitance (470 µF), voltage rating (16 V), tolerance (±20%), lead spacing (5.00 mm), and through-hole mounting. The reduced height (14.00 mm versus 16.00 mm) requires PCB layout verification but does not affect electrical function.

Q: What is the difference between EEU-FM1C471 and EEU-FM1C471B?

A: Both parts are electrically identical with matching capacitance, voltage, and tolerance specifications. The primary difference is packaging: EEU-FM1C471 is supplied in bulk packaging, while EEU-FM1C471B is supplied in cut-tape format. Inventory levels differ accordingly (26305 units bulk versus 3491 units cut-tape).

Q: Can 25 V rated parts substitute for the 16 V original specification?

A: Yes, 25 V rated parts are electrically compatible and provide enhanced voltage margin. However, physical dimensions increase (height 16.00-17.50 mm versus original 16.00 mm). PCB layout verification is required to confirm clearance and mounting compatibility. Circuit design must permit the higher voltage rating.

Q: Why are some substitute parts marked "Not For New Designs"?

A: Parts designated "Not For New Designs" indicate manufacturer discontinuation plans or transition to newer product lines. While technically functional, these parts are not recommended for new circuit designs due to uncertain long-term availability and potential future discontinuation.

Q: What does REACH-affected status mean for component selection?

A: REACH-affected status indicates the component contains substances subject to European chemical regulations. For applications requiring REACH compliance or serving European markets, select parts with "REACH Unaffected" status such as Panasonic or Chemi-Con alternatives.

Q: How do lifetime specifications (4000 hrs vs. 7000 hrs @ 105°C) affect substitution?

A: Lifetime specifications define expected operational duration under rated conditions. Parts with extended lifetime (7000 hours) provide longer service intervals and enhanced reliability margin. Direct substitution is valid regardless of lifetime difference, but applications requiring extended operational life benefit from higher-rated alternatives.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance status, matching the original SXR471M016ST specification. This ensures regulatory compliance for applications subject to RoHS requirements.

Q: What inventory considerations apply to part selection?

A: EKZE250ELL471MJ16S (Chemi-Con) offers the highest inventory availability at 61340 units, providing supply security for high-volume applications. EEU-FM1C471B (Panasonic) offers 3491 units in cut-tape format for moderate-volume requirements. Inventory levels should be verified with suppliers for current availability.
