ELXM251VSN271MP35S Equivalent & Substitute Parts

Part Overview

The ELXM251VSN271MP35S is a 270 µF, 250 V aluminum electrolytic capacitor manufactured by Chemi-Con in the LXM series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with 732 pieces in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate components with enhanced performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence in the following parameters:

• Capacitance Value: 270 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Configuration: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Physical Dimensions: 0.866" diameter × 1.457" height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The substitute part LGR2E271MELZ35 manufactured by Nichicon meets all these critical parameters, enabling direct substitution in circuit designs. Secondary performance enhancements in the substitute part (extended lifetime and expanded operating temperature range) do not affect substitution eligibility but may provide additional design margin.

Parameter Comparison

Engineering Selection Recommendations

Both the ELXM251VSN271MP35S and LGR2E271MELZ35 are active production components with full regulatory compliance. The Chemi-Con ELXM251VSN271MP35S is RoHS Compliant and REACH Unaffected. The Nichicon LGR2E271MELZ35 is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Selection between these parts should be based on availability and supply chain requirements. The Nichicon LGR2E271MELZ35 offers extended operational lifetime (10000 hours at 105°C versus 7000 hours) and a wider operating temperature range (-40°C to 105°C versus -25°C to 105°C), which may provide additional design margin in applications subject to temperature extremes or requiring extended service life.

Both parts are electrically and mechanically interchangeable for applications requiring 270 µF, 250 V aluminum electrolytic capacitors in radial snap-in configuration with through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can the LGR2E271MELZ35 be used as a direct replacement for the ELXM251VSN271MP35S?

A: Yes. Both capacitors share identical electrical specifications (270 µF, 250 V, ±20% tolerance) and mechanical dimensions (0.866" diameter, 1.457" height, 0.394" lead spacing). The radial snap-in package and through-hole mounting configuration are identical, enabling direct substitution on printed circuit boards without layout modifications.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Chemi-Con versus Nichicon), lifetime rating (7000 hours versus 10000 hours at 105°C), and operating temperature range (-25°C to 105°C versus -40°C to 105°C). Ripple current ratings are nearly identical. Both parts meet current RoHS and REACH compliance requirements.

Q: Are there any compatibility concerns with PCB mounting?

A: No. Both parts use identical lead spacing (0.394" / 10.00 mm) and physical dimensions. PCB footprints designed for either part will accommodate the other without modification.

Q: Which part should be selected for applications in cold environments?

A: The Nichicon LGR2E271MELZ35 is rated for operation down to -40°C, compared to -25°C for the Chemi-Con part. For applications requiring operation below -25°C, the Nichicon part is the appropriate selection.

Q: Do these capacitors have different moisture sensitivity levels?

A: The ELXM251VSN271MP35S has MSL 1 (Unlimited). The LGR2E271MELZ35 lists MSL as Not Applicable. Both parts are suitable for standard handling and storage conditions without special moisture control requirements.
