Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10TPB100M is determined by the following core parameters:

• Capacitance Value: 100 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Component Type: Molded Tantalum Polymer Capacitor (exact match required)

Both substitute parts meet these criteria. The 10TPC100M is the manufacturer-recommended direct replacement from Panasonic Electronic Components, maintaining the same product line evolution within the POSCAP™ TPC series. The TR3D107K010C0065 from Vishay Sprague provides an alternative from a different manufacturer while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 10TPC100M (Panasonic Electronic Components)

The 10TPC100M is the recommended direct replacement for the obsolete 10TPB100M. Both components are manufactured by Panasonic Electronic Components and share identical electrical ratings (100 µF, 10 V) and package specifications (2917 / 7343 Metric). The 10TPC100M is classified as Active product status, ensuring long-term availability and supply chain continuity. This part carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The lower seated height (0.079" vs. 0.122" for the Vishay alternative) and lower ESR (45mOhm @ 100kHz) provide improved thermal performance and reduced power dissipation in circuit applications.

Alternative Substitute: TR3D107K010C0065 (Vishay Sprague)

The TR3D107K010C0065 from Vishay Sprague provides a cross-manufacturer alternative meeting all core electrical and mechanical compatibility parameters. This part maintains the same 100 µF capacitance, 10 V voltage rating, and 2917 package footprint. The TR3D107K010C0065 offers tighter capacitance tolerance (±10% vs. ±20% for the Panasonic substitute) and an extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C). However, the higher ESR (65mOhm) and greater seated height (0.122" vs. 0.079") should be evaluated against specific circuit thermal and space constraints. This part is also ROHS3 compliant and REACH Unaffected.

Both substitutes are classified as Active products with current manufacturing and distribution support, providing reliable alternatives to the obsolete 10TPB100M.

Frequently Asked Questions (FAQ)

Q: What makes the 10TPC100M and TR3D107K010C0065 suitable substitutes for the 10TPB100M?

A: Both substitute parts maintain the core electrical specifications (100 µF capacitance, 10 V voltage rating) and mechanical compatibility (2917 / 7343 Metric package, surface mount configuration) required for direct substitution. The 10TPB100M is obsolete, making these active alternatives necessary for continued design support and production.

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

A: Yes. The 10TPC100M has a maximum seated height of 0.079" (2.00mm), while the TR3D107K010C0065 has a maximum seated height of 0.122" (3.10mm). Both fit the 2917 package footprint, but board-level clearance and component stacking must be verified for the Vishay part in space-constrained applications. The lateral dimensions (0.287" L x 0.169" W) are identical for both substitutes.

Q: How do the electrical characteristics differ between the substitutes?

A: The 10TPC100M provides lower ESR (45mOhm @ 100kHz) compared to the TR3D107K010C0065 (65mOhm), resulting in reduced power dissipation and improved thermal performance. The Vishay part offers tighter capacitance tolerance (±10% vs. ±20%) and a wider operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C). Circuit requirements for ripple current handling and temperature stability should guide selection between these alternatives.

Q: Are both substitutes compliant with current regulatory standards?

A: Yes. Both the 10TPC100M and TR3D107K010C0065 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Both carry EAR99 ECCN classification and 8532.21.0050 HTSUS code, matching the original part's trade classification.

Q: Which substitute should be selected for new designs?

A: The 10TPC100M is the primary recommendation for new designs, as it is the manufacturer-recommended replacement from Panasonic Electronic Components with superior thermal characteristics (lower ESR and height). The TR3D107K010C0065 is suitable when tighter capacitance tolerance or extended temperature range is required, provided board-level space and thermal constraints are satisfied.

Q: Can these parts be used interchangeably in existing assemblies?

A: Physical and electrical compatibility is confirmed for both substitutes within the specified parameters. However, the difference in seated height between the 10TPC100M (0.079") and TR3D107K010C0065 (0.122") must be verified against PCB clearance and component placement constraints in existing designs before implementation.
