Equivalent & Substitute Parts for M39006/09-8511

Part Overview

The M39006/09-8511 is a 100 µF hermetically sealed tantalum capacitor rated at 30 V, designed for military applications under MIL-PRF-39006/09 specification. This axial through-hole component operates across a temperature range of -55°C to 125°C and is classified as obsolete. Due to its obsolete status and RoHS non-compliance, identifying functionally equivalent alternatives is necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

No direct substitute parts are currently available in the provided database. Substitution for the M39006/09-8511 requires identification of alternative components that meet the following critical parameters:

• Capacitance: 100 µF (±20% tolerance acceptable)
• Voltage Rating: 30 V minimum
• Type: Hermetically sealed tantalum capacitor
• Mounting: Through-hole axial configuration
• Temperature Range: -55°C to 125°C operation
• Reliability: Military-grade or equivalent high-reliability classification
• Compliance: Preference for RoHS-compliant alternatives where available

Substitutes must maintain electrical performance within the specified tolerance and mechanical compatibility with axial lead spacing and dimensional constraints (0.406" Dia × 0.828" L).

Parameter Comparison

No substitute parts are available for comparison at this time. When alternatives are identified, comparison will include capacitance, voltage rating, temperature range, package type, and compliance certifications.

Engineering Selection Recommendations

Given the obsolete status of M39006/09-8511, component selection should prioritize:

• Military-specification tantalum capacitors meeting MIL-PRF-39006 or equivalent standards
• RoHS-compliant alternatives to address environmental and regulatory requirements
• Hermetically sealed construction to maintain reliability in demanding applications
• Axial through-hole packaging for direct mechanical compatibility
• Verified high-reliability ratings consistent with the original P (0.1%) failure rate classification

When no direct equivalent exists, design review may require evaluation of surface-mount alternatives or non-tantalum capacitor technologies with equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: What makes a component a valid substitute for M39006/09-8511? A: A valid substitute must match the 100 µF capacitance, 30 V voltage rating, hermetically sealed tantalum construction, axial through-hole package, and -55°C to 125°C operating range. Tolerance and failure rate classifications should align with military-grade specifications.

Q: Can surface-mount tantalum capacitors replace this axial component? A: No. The M39006/09-8511 requires through-hole axial mounting. Surface-mount alternatives would necessitate PCB redesign and are not direct mechanical substitutes.

Q: Why is RoHS compliance important for substitution? A: The original M39006/09-8511 is RoHS non-compliant. Substitutes with RoHS compliance address environmental regulations and may be required for new designs or systems subject to RoHS directives.

Q: Are there non-tantalum alternatives? A: Substitution with non-tantalum capacitor technologies (ceramic, film, or aluminum electrolytic) requires detailed electrical performance analysis and is not a direct equivalent replacement.

Q: How does the ±20% tolerance affect substitution? A: Components with ±20% tolerance or tighter (±10%, ±5%) are acceptable substitutes. Looser tolerances do not meet the specification.
