Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 10TPC33MB is determined by the following critical parameters: capacitance value (33 µF), package type (1411/3528 Metric), surface mount configuration, and operating temperature range (-55°C ~ 105°C). Voltage rating may be increased without functional degradation in applications where the circuit design permits higher voltage tolerance. All substitute parts maintain identical capacitance, package dimensions, and thermal operating range as the original component.

The substitute parts are categorized as follows:

Direct Manufacturer Equivalent (12TPG33M): Same capacitance and package; voltage rating increased to 12.5 V with specified ESR characteristics.

Manufacturer Recommended Substitute (16TQC33MYFB): Same capacitance and package; voltage rating increased to 16 V with enhanced ESR performance and active product status.

Similar Substitute (10TPB33M): Identical voltage rating and capacitance; same package with improved ESR specification and active product status.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with identical electrical specifications: The 10TPB33M is the preferred choice. It maintains the original 10 V voltage rating and 33 µF capacitance while offering active product status and improved ESR performance (70mOhm @ 100kHz). The increased seated height (2.00mm versus 1.20mm) must be verified against PCB layout constraints.

For applications permitting higher voltage tolerance: The 16TQC33MYFB is the manufacturer-recommended substitute. It provides the highest voltage rating (16 V), active product status, and the largest inventory availability (20,100 pcs). The increased seated height (2.00mm) and higher ESR (90mOhm @ 100kHz) must be evaluated against circuit performance requirements.

For transitional procurement: The 12TPG33M offers an intermediate voltage rating (12.5 V) with specified ESR characteristics (70mOhm @ 100kHz). This part carries Last Time Buy status and should be considered only if inventory constraints or design requirements necessitate this specific voltage rating.

All substitute parts maintain ROHS3 compliance and the identical operating temperature range (-55°C ~ 105°C) as the original component.

Frequently Asked Questions (FAQ)

Q: Can the 16TQC33MYFB be used as a direct replacement for the 10TPC33MB?

A: Yes, from an electrical and mechanical standpoint. The 16TQC33MYFB maintains identical capacitance (33 µF) and package dimensions (1411/3528 Metric). The higher voltage rating (16 V versus 10 V) is compatible with circuits designed for 10 V operation. However, the seated height increases from 1.20mm to 2.00mm, requiring PCB layout verification.

Q: What is the significance of the ESR difference between substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The 10TPB33M and 12TPG33M both specify 70mOhm @ 100kHz, while the 16TQC33MYFB specifies 90mOhm @ 100kHz. Higher ESR may impact performance in high-frequency or high-ripple-current applications.

Q: Why does the 10TPC33MB have no specified ESR value?

A: The original part is obsolete, and complete technical specifications may not be available in current documentation. This underscores the importance of transitioning to active product alternatives.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are available in Tape & Reel (TR) packaging. The original 10TPC33MB packaging format is not specified in the provided data.

Q: What is the impact of the increased seated height on PCB design?

A: The 10TPB33M and 16TQC33MYFB have a maximum seated height of 2.00mm, compared to 1.20mm for the original 10TPC33MB. This 0.80mm increase must be verified against PCB clearance requirements, particularly in applications with height constraints or multilayer board configurations.

Q: Which substitute part offers the best long-term availability?

A: The 16TQC33MYFB carries Active product status with the highest inventory (20,100 pcs), ensuring long-term availability and supply chain stability.
