Key Parameters

Substitute Part Grouping Explanation

Substitution of the PTGL16AS330H0B02BZ is determined by the following critical parameters:

• Functional Category: Inrush Current Limiter
• Resistance Value: 33 Ohms nominal
• Current Rating: Steady-state maximum of 39 A
• Physical Form Factor: Cylindrical component with 0.630" (16.00mm) diameter
• Regulatory Compliance: ROHS3 compliance required

The identified substitute, B59451C1130B070 from EPCOS - TDK Electronics, operates within the allowed tolerance and regulatory framework for this application category. The substitute maintains functional equivalence as an inrush current limiter while meeting modern compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The B59451C1130B070 is an active product with current manufacturing support from EPCOS - TDK Electronics, providing supply chain continuity for the obsolete PTGL16AS330H0B02BZ. Both components maintain ROHS3 compliance and share the same ECCN and HTSUS classifications, confirming regulatory alignment.

The substitute carries AEC-Q200 automotive qualification, indicating compliance with automotive-grade reliability standards. The MSL rating of 1 (Unlimited) for the substitute provides superior moisture handling characteristics compared to the original component's Not Applicable rating.

Physical dimensions differ between the two components: the substitute features a 0.591" (15.00mm) diameter versus the original 0.630" (16.00mm), and reduced lead spacing of 0.197" (5.00mm) versus 0.394" (10.00mm). These dimensional variations require verification against mechanical mounting and circuit board layout constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can B59451C1130B070 directly replace PTGL16AS330H0B02BZ in existing designs?

A: Functional equivalence as an inrush current limiter is established. However, the dimensional differences in diameter and lead spacing require mechanical compatibility assessment. Circuit board layout and mounting fixture modifications may be necessary.

Q: What are the key differences between these components?

A: The primary differences are physical form factor (diameter and lead spacing) and product status. The substitute is an active product with automotive-grade qualification, while the original is obsolete. Both maintain ROHS3 compliance and equivalent regulatory classification.

Q: Is the tolerance specification relevant for substitution?

A: The B59451C1130B070 carries a ±25% tolerance specification. This tolerance parameter must be evaluated against the circuit design requirements to confirm functional suitability in the target application.

Q: What is the significance of AEC-Q200 qualification on the substitute?

A: AEC-Q200 qualification indicates the substitute meets automotive-grade reliability and testing standards. This certification is relevant only if the application requires automotive-grade components.

Q: Are there any supply chain advantages to using the substitute?

A: Yes. The B59451C1130B070 is an active product with 2100 pieces in current inventory, compared to the obsolete PTGL16AS330H0B02BZ. Active product status ensures ongoing availability and manufacturing support.
