DX-5R5L334T Equivalent & Substitute Parts

Part Overview

The DX-5R5L334T is a 330 mF supercapacitor (EDLC) rated at 5.5 V with through-hole axial mounting. This component is classified as Obsolete and no longer recommended for new designs. The part features 75Ohm equivalent series resistance (ESR) and a rated lifetime of 1000 hours at 70°C. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing maintenance, repair, and legacy system support.

Substitute Part Grouping Explanation

Substitution of the DX-5R5L334T is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 330 mF (exact match required)
• Voltage Rating: 5.5 V (exact match required)
• Tolerance: -20%, +80% (exact match required)
• ESR: 75Ohm (exact match required)
• Lifetime: 1000 Hrs @ 70°C (exact match required)
• Operating Temperature: -25°C ~ 70°C (exact match required)

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial, Can - Vertical (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Termination: PC Pins (exact match required)

The substitute part RSCX13345R5F13013U meets all electrical and mechanical equivalence criteria. Physical height variation (0.488" vs. 0.532") does not affect functional substitution in through-hole applications with standard PCB clearance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement:

RSCX13345R5F13013U is the direct functional equivalent of DX-5R5L334T. Both parts are manufactured by Elna America within the DX series and share identical electrical specifications (330 mF, 5.5 V, -20%/+80% tolerance, 75Ohm ESR, 1000 Hrs @ 70°C). Both components maintain ROHS3 compliance and REACH unaffected status.

Compliance Considerations:

Both the main part and substitute are classified as legacy components (Obsolete and Not For New Designs respectively). Selection between these parts should be based on inventory availability and packaging requirements. The main part (DX-5R5L334T) is available in 971 pieces, while the substitute (RSCX13345R5F13013U) has significantly higher inventory at 27,463 pieces.

Packaging Distinction:

The primary difference between these parts is packaging designation: DX-5R5L334T is specified as tape/reel packaging, while RSCX13345R5F13013U is supplied in bulk. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

Physical Clearance:

The height difference of 0.044" (1.10mm) between seated heights is within standard PCB through-hole clearance tolerances and does not restrict substitution in typical applications.

Frequently Asked Questions (FAQ)

Q: Can RSCX13345R5F13013U replace DX-5R5L334T in existing designs?

A: Yes. RSCX13345R5F13013U is electrically and mechanically equivalent to DX-5R5L334T across all specified parameters: capacitance (330 mF), voltage rating (5.5 V), tolerance (-20%, +80%), ESR (75Ohm), lifetime (1000 Hrs @ 70°C), and through-hole axial mounting configuration.

Q: What is the significance of the height difference (0.488" vs. 0.532")?

A: The 0.044" (1.10mm) height difference falls within standard PCB design clearance margins for through-hole components. This variation does not affect functional substitution in applications with conventional board spacing and does not require PCB redesign.

Q: Why are both parts classified as legacy (Obsolete / Not For New Designs)?

A: Both DX-5R5L334T and RSCX13345R5F13013U are supercapacitors from the DX series that have been superseded in Elna America's current product portfolio. These classifications indicate that while the parts remain available from existing inventory, they are not recommended for new product development. Substitution is appropriate for maintenance and repair of existing systems only.

Q: What is the difference between tape/reel and bulk packaging?

A: Tape/reel packaging (DX-5R5L334T) is designed for automated assembly processes and provides components on continuous carrier tape. Bulk packaging (RSCX13345R5F13013U) supplies components in loose form. Both packaging formats contain identical components with identical electrical and mechanical specifications. Packaging selection depends on procurement method and assembly requirements.

Q: Are there compliance differences between these parts?

A: No. Both parts maintain identical compliance status: ROHS3 compliant and REACH unaffected. No additional regulatory considerations apply to substitution.

Q: What inventory considerations should guide part selection?

A: DX-5R5L334T has 971 pieces in stock, while RSCX13345R5F13013U has 27,463 pieces available. For applications requiring immediate availability or high-volume procurement, RSCX13345R5F13013U offers superior inventory position.
