DX-5R5L473T Equivalent & Substitute Parts

Part Overview

The DX-5R5L473T is a 47 mF supercapacitor (EDLC) manufactured by Elna America, rated for 5.5 V operation with through-hole axial mounting. This component is classified as Obsolete and no longer recommended for new designs. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for maintenance, repair, and legacy system support where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DX-5R5L473T is determined by strict electrical and mechanical parameter matching:

Electrical Equivalence Criteria:

• Capacitance value: 47 mF (exact match required)
• Voltage rating: 5.5 V (minimum acceptable)
• ESR: 120 Ohm (performance-critical parameter)
• Lifetime specification: 1000 Hrs @ 70°C (reliability baseline)

Mechanical Compatibility Criteria:

• Mounting type: Through Hole (PCB assembly method)
• Package form: Axial, Can - Vertical (physical envelope)
• Lead spacing: 0.197" (5.00 mm) (hole pattern match)
• Operating temperature range: -25°C ~ 70°C (environmental tolerance)

Regulatory Compliance:

• RoHS3 Compliant status required for new component selection

The substitute part RSCX14735R5F13013U meets all electrical and mechanical parameters specified above, with the exception of physical height dimension (13.50 mm vs. 5.00 mm seated height), which may require board layout verification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

RSCX14735R5F13013U is electrically and mechanically compatible with DX-5R5L473T for applications where the increased seated height (13.50 mm vs. 5.00 mm) does not create physical interference on the PCB. Both parts are manufactured by Elna America, share identical electrical specifications (47 mF, 5.5 V, 120 Ohm ESR, 1000 Hrs @ 70°C), and maintain ROHS3 compliance.

Product Status Consideration:

Both the main part (Obsolete) and substitute part (Not For New Designs) carry restricted product status designations. The substitute part RSCX14735R5F13013U remains available in higher inventory (11,891 Pcs) compared to the main part (1,033 Pcs), making it the practical choice for legacy system support and field replacement applications.

Compliance Verification:

Both parts maintain identical regulatory compliance: ROHS3 Compliant, REACH Unaffected, and ECCN EAR99 classification. No compliance barriers exist for substitution.

Physical Fit Verification Required:

The height difference (8.50 mm additional) must be verified against PCB clearance, component spacing, and enclosure constraints before implementation.

Frequently Asked Questions (FAQ)

Q: Can RSCX14735R5F13013U be used as a direct replacement for DX-5R5L473T?

A: Yes, for electrical function. All electrical parameters are identical: 47 mF capacitance, 5.5 V rating, 120 Ohm ESR, and 1000 Hrs @ 70°C lifetime. However, the substitute part is 8.50 mm taller (13.50 mm vs. 5.00 mm seated height). Physical board layout must be verified to confirm clearance compatibility.

Q: What are the critical parameters that must match for substitution?

A: Capacitance (47 mF), voltage rating (5.5 V), ESR (120 Ohm), lifetime specification (1000 Hrs @ 70°C), mounting type (Through Hole), package form (Axial, Can - Vertical), and lead spacing (0.197" / 5.00 mm). All these parameters are identical between the main part and substitute.

Q: Why is the substitute part listed as "Not For New Designs"?

A: Both the main part and substitute are from the obsolete DX series. The "Not For New Designs" status indicates the substitute is also legacy inventory. For new designs, current-generation supercapacitor alternatives from Elna America or other manufacturers should be evaluated.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as ECCN EAR99. Regulatory compliance is identical.

Q: What is the lead spacing, and why does it matter?

A: Lead spacing is 0.197" (5.00 mm) for both parts. This dimension determines PCB hole pattern compatibility. Both parts use identical spacing, ensuring through-hole PCB assembly compatibility.

Q: Can I use this part in applications outside the -25°C ~ 70°C operating range?

A: No. Both parts are specified for -25°C ~ 70°C operation. Use outside this range is not supported by the manufacturer specifications provided.

Q: What does ESR (Equivalent Series Resistance) of 120 Ohm mean for my application?

A: ESR determines the internal resistance of the supercapacitor, affecting power delivery capability, charging/discharging speed, and heat generation. Both parts have identical 120 Ohm ESR, ensuring equivalent performance in power delivery applications.

Q: Is the packaging difference (Bulk vs. standard) significant?

A: Packaging designation (Bulk for RSCX14735R5F13013U) refers to order quantity and delivery format, not component function. Electrical and mechanical specifications are identical regardless of packaging type.
