TDL106K035M2D-F Equivalent & Substitute Parts

Part Overview

The TDL106K035M2D-F is a 10 µF conformal coated tantalum capacitor rated at 35 V in radial through-hole packaging manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, necessitating the identification of active equivalent alternatives that maintain the same electrical and mechanical performance characteristics. The availability of active substitutes ensures design continuity and supply chain reliability for legacy and current applications requiring conformal coated tantalum capacitors with these specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TDL106K035M2D-F is determined by strict electrical and mechanical compatibility across the following key parameters:

Electrical Parameters (Must Match):

• Capacitance: 10 µF
• Tolerance: ±10%
• Voltage - Rated: 35 V
• Type: Conformal Coated
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Primary Consideration):

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.200" (5.08mm)
• Manufacturer Size Code: D

Regulatory Compliance:

• RoHS Status: ROHS3 Compliant

The substitute parts listed below (199D106X9035D6V1E3, 199D106X9035D1V1E3, and 199D106X9035D2V1E3) maintain all specified electrical parameters and operate within the same temperature range. Mechanical dimensions vary in diameter and height characteristics while maintaining the critical 0.200" lead spacing required for PCB compatibility with the original TDL106K035M2D-F design.

Parameter Comparison

Engineering Selection Recommendations

199D106X9035D6V1E3 (Direct Substitute - Preferred for Original Lead Spacing)

This Vishay Sprague TANTALEX™ 199D series part maintains the original 0.200" (5.08mm) lead spacing, providing direct PCB compatibility without layout modifications. The part is in active production status, ensuring long-term availability and supply continuity. All electrical specifications match the TDL106K035M2D-F, and it carries ROHS3 compliance. This substitution requires no design changes to existing PCB layouts.

199D106X9035D1V1E3 and 199D106X9035D2V1E3 (Alternative Substitutes - Reduced Lead Spacing)

Both parts provide electrical equivalence to the original TDL106K035M2D-F with identical capacitance, voltage rating, tolerance, and operating temperature range. However, these variants feature a reduced lead spacing of 0.100" (2.54mm), requiring PCB layout modifications for pin hole repositioning. These parts are in active production and carry ROHS3 compliance. Selection of these alternatives is appropriate only when PCB redesign is feasible and lead spacing adjustment can be accommodated.

All three substitute parts provide superior reliability documentation (1000 Hrs @ 85°C lifetime specification) compared to the original obsolete part, which had no specified lifetime rating.

Frequently Asked Questions (FAQ)

Q: Can I use any of these Vishay Sprague substitutes as a drop-in replacement for the TDL106K035M2D-F?

A: The 199D106X9035D6V1E3 is a direct drop-in replacement, maintaining the same 0.200" (5.08mm) lead spacing. The 199D106X9035D1V1E3 and 199D106X9035D2V1E3 require PCB modifications due to their 0.100" (2.54mm) lead spacing.

Q: What electrical parameters must match when selecting a substitute?

A: Capacitance (10 µF), tolerance (±10%), voltage rating (35 V), type (conformal coated), and operating temperature range (-55°C ~ 125°C) must all remain constant for functional equivalence.

Q: Are there dimensional differences between the main part and substitutes?

A: Yes. The TDL106K035M2D-F has a diameter of 0.340" (8.64mm), while the Vishay Sprague substitutes have a 0.236" (6.00mm) diameter. Lead spacing differs significantly between the direct substitute (199D106X9035D6V1E3 at 0.200") and the alternative variants (0.100"). Heights range from 0.400" to 0.498" depending on the variant.

Q: What is the significance of the conformal coating?

A: Conformal coating provides environmental protection and is a critical functional requirement. All identified substitutes maintain this coating type, ensuring equivalent performance in harsh or moisture-prone operating environments.

Q: Why is the Vishay Sprague part preferred despite being a different manufacturer?

A: The Vishay Sprague 199D series substitutes are in active production (ensuring long-term supply), carry ROHS3 compliance, and provide documented reliability ratings. The original CDE part is obsolete and no longer manufactured.

Q: What is MSL, and why does it differ between the main part and substitutes?

A: MSL (Moisture Sensitivity Level) indicates the part's sensitivity to moisture during storage and handling. The TDL106K035M2D-F has MSL 1 (unlimited shelf life), while the Vishay Sprague substitutes are Not Applicable, indicating conformal coated tantalum capacitors that do not require moisture-sensitive device handling protocols.
