Equivalent & Substitute Parts for 276KXM063M

Part Overview

The 276KXM063M is a 27 µF, 63 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the KXM series. This radial, through-hole component is designed for general-purpose applications with a rated lifetime of 2000 hours at 105°C and an operating temperature range of -55°C to 105°C. The part is currently active in production status and ROHS3 compliant.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design flexibility requires alternative sourcing from qualified manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 276KXM063M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 27 µF (exact match required)
• Voltage rating: 63 V (minimum, no downrating permitted)
• Tolerance: ±20% (matching tolerance classification)
• Lifetime specification: 2000 Hrs @ 105°C (minimum requirement)
• Operating temperature range: -55°C to 105°C (full range coverage required)
• Polarization: Polar (unidirectional polarity required)

Mechanical Parameters:

• Package type: Radial, Can (form factor match required)
• Mounting type: Through Hole (PCB connection method match required)
• Lead spacing: 0.098" (2.50 mm) (footprint compatibility required)
• Diameter: 0.248" (6.30 mm) (physical envelope match required)
• Height seated maximum: tolerance within 0.492" (12.50 mm) reference (board clearance consideration)

Compliance Parameters:

• RoHS3 compliance (regulatory requirement match)
• REACH unaffected status (supply chain requirement match)

The UPJ1J270MED from Nichicon meets all critical electrical and mechanical substitution criteria, despite its obsolete product status classification.

Engineering Selection Recommendations

276KXM063M (Primary Selection): The 276KXM063M remains the preferred selection for new designs and ongoing production. This component carries active product status from Cornell Dubilier / Illinois Capacitor, ensuring long-term availability and supply chain stability. Current inventory of 860 pieces supports immediate procurement requirements.

UPJ1J270MED (Substitute Selection): The UPJ1J270MED from Nichicon is a qualified substitute for applications where the primary part becomes unavailable. This component satisfies all critical electrical parameters (27 µF, 63 V, ±20%, 2000 Hrs @ 105°C) and mechanical requirements (radial through-hole, 0.098" lead spacing, 6.30 mm diameter). The UPJ1J270MED is ROHS3 compliant and REACH unaffected, meeting regulatory requirements.

The UPJ1J270MED carries obsolete product status classification. This designation indicates the part is no longer in active production but remains available through existing inventory channels (1819 pieces currently in stock). Selection of this substitute should account for long-term availability constraints and potential future sourcing limitations.

The 0.020" height difference (UPJ1J270MED at 12.00 mm versus 276KXM063M at 12.50 mm) presents no functional or mechanical compatibility issues for through-hole mounting applications and improves board clearance margins.

Frequently Asked Questions (FAQ)

Q: Can the UPJ1J270MED be used as a direct replacement for the 276KXM063M in existing designs?

A: Yes. The UPJ1J270MED meets all critical electrical and mechanical specifications. Capacitance (27 µF), voltage rating (63 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C to 105°C), lead spacing (0.098" / 2.50 mm), and package type (radial through-hole) are identical. The UPJ1J270MED is 0.020" shorter in height, which is compatible with existing PCB layouts.

Q: What is the significance of the "obsolete" product status for the UPJ1J270MED?

A: Obsolete status indicates the UPJ1J270MED is no longer manufactured by Nichicon. However, 1819 pieces are currently available in inventory. This status should be considered for long-term production planning. For applications requiring extended component availability, the active-status 276KXM063M is the recommended primary selection.

Q: Are there electrical performance differences between these two parts?

A: Both parts meet the specified 2000-hour lifetime at 105°C and operate across the -55°C to 105°C temperature range. The 276KXM063M specifies ESR of 6.1402 Ohm @ 120 Hz and impedance of 860 mOhms. The UPJ1J270MED specifies lower impedance at 640 mOhms, indicating superior high-frequency performance characteristics. Both parts support the specified ripple current requirements at their respective frequency ratings.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 276KXM063M and UPJ1J270MED are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic component procurement.

Q: What is the lead spacing specification, and why is it important?

A: Both parts specify 0.098" (2.50 mm) lead spacing. This measurement defines the distance between the two radial leads and determines PCB footprint compatibility. Identical lead spacing ensures direct mechanical and electrical compatibility without PCB redesign.

Q: Can the UPJ1J270MED be used in high-frequency applications?

A: The UPJ1J270MED supports ripple current of 240 mA @ 10 kHz, indicating suitability for high-frequency applications within this specification. The 276KXM063M supports ripple current of 240 mA @ 100 kHz, providing broader high-frequency capability. Application-specific frequency requirements should be evaluated against the ripple current specifications of each part.
