VS-16TTS08FPPBF Equivalent & Substitute Parts

Part Overview

The VS-16TTS08FPPBF is an SCR (Silicon Controlled Rectifier) thyristor rated for 800V off-state voltage and 16A RMS on-state current in a TO-220AB through-hole package. Manufactured by Vishay General Semiconductor - Diodes Division, this component is classified as obsolete. Finding equivalent substitute parts is necessary due to the discontinued status of the original part number, requiring engineers to identify functionally compatible alternatives that maintain electrical and mechanical compatibility in existing designs.

Substitute Part Grouping Explanation

Substitution of the VS-16TTS08FPPBF is determined by strict equivalence across the following critical parameters:

Off-state voltage rating: 800 V minimum
RMS on-state current rating: 16 A minimum
Gate trigger voltage (Vgt): 2 V maximum
Gate trigger current (Igt): 60 mA maximum
On-state voltage drop (Vtm): 1.4 V maximum
Package type: TO-220-3 Full Pack through-hole configuration
SCR type: Standard Recovery
Operating temperature range: -40°C to 125°C minimum

The substitute part VS-16TTS08FP-M3 meets all these criteria and is manufactured by the same supplier, ensuring electrical and mechanical compatibility. The primary distinction is product status: the substitute is active and available, whereas the original part is obsolete.

Engineering Selection Recommendations

The VS-16TTS08FP-M3 is the direct substitute for the obsolete VS-16TTS08FPPBF. Both parts are ROHS3 compliant and manufactured by Vishay General Semiconductor - Diodes Division, ensuring regulatory and quality consistency. The substitute part is currently active and available in inventory, making it the appropriate choice for new designs and replacement applications.

The substitute maintains all critical electrical parameters within the same specifications. Minor variations in hold current (150 mA vs. 100 mA) and off-state leakage current (10 mA vs. 500 µA) remain within acceptable engineering tolerances for standard recovery SCR applications. The non-repetitive surge current rating of the substitute (170 A) is slightly lower than the original (200 A), which should be evaluated against specific application surge requirements.

Frequently Asked Questions (FAQ)

Q: Can VS-16TTS08FP-M3 be used as a direct replacement for VS-16TTS08FPPBF?

A: Yes. Both parts share identical voltage ratings (800 V off-state), current ratings (16 A RMS), gate trigger specifications (2 V, 60 mA), and package configuration (TO-220-3 Full Pack through-hole). The substitute is electrically and mechanically compatible.

Q: What are the differences between these two part numbers?

A: The primary difference is product status: VS-16TTS08FPPBF is obsolete, while VS-16TTS08FP-M3 is active. Secondary differences include hold current (150 mA vs. 100 mA), off-state leakage current (10 mA vs. 500 µA), and non-repetitive surge current (170 A vs. 200 A). These variations do not affect compatibility in standard applications.

Q: Are there packaging differences?

A: The substitute part is supplied in tube packaging, whereas the original part number does not specify a packaging format. Both use the same TO-220-3 Full Pack component package for mounting.

Q: Do both parts meet the same compliance standards?

A: Yes. Both VS-16TTS08FPPBF and VS-16TTS08FP-M3 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.30.0080.

Q: Which part should be selected for new designs?

A: VS-16TTS08FP-M3 should be selected for new designs due to its active product status and current availability. The obsolete status of VS-16TTS08FPPBF makes it unsuitable for new applications.
