VS-16TTS16STRLPBF Equivalent & Substitute Parts

Part Overview

The VS-16TTS16STRLPBF is a 1.6 kV, 16 A standard recovery SCR (silicon-controlled rectifier) in TO-263AB (D2PAK) surface mount packaging manufactured by Vishay General Semiconductor - Diodes Division. This thyristor is designed for high-voltage switching applications requiring reliable gate-triggered control. The main part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives with identical electrical specifications and packaging are available from the same manufacturer.

Substitute Part Grouping Explanation

Substitution for the VS-16TTS16STRLPBF is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts VS-16TTS16STRL-M3 and VS-16TTS16STRR-M3 are qualified as direct equivalents based on the following criteria:

Key Parameters for Substitution:

• Off-state voltage: 1.6 kV (identical)
• Gate trigger voltage and current: 2 V / 60 mA (identical)
• On-state voltage and current ratings: 1.4 V / 16 A RMS (identical)
• Hold current: 150 mA (identical)
• SCR type: Standard Recovery (identical)
• Operating temperature range: -40°C to 125°C (identical)
• Package and mounting: TO-263AB surface mount (identical)
• Compliance: ROHS3 compliant (identical)

The primary difference between substitutes is packaging format (bulk vs. tape & reel) and product status (discontinued vs. active). All three parts share the same base product number (16TTS16) and are manufactured by Vishay General Semiconductor - Diodes Division.

Parameter Comparison

Engineering Selection Recommendations

Both VS-16TTS16STRL-M3 and VS-16TTS16STRR-M3 are direct functional equivalents to the discontinued VS-16TTS16STRLPBF. Selection between them depends on procurement and assembly requirements:

VS-16TTS16STRL-M3 is the primary substitute for applications requiring direct replacement. It maintains active product status, ROHS3 compliance, and identical electrical specifications. The tape & reel packaging format is standard for automated assembly processes.

VS-16TTS16STRR-M3 is an alternative equivalent with identical core electrical parameters and active status. It also features tape & reel packaging and ROHS3 compliance.

Both substitutes provide improved non-repetitive surge current ratings (200 A @ 50Hz vs. 170 A @ 50Hz for the original part), representing enhanced performance margins. All three parts are manufactured by the same supplier and share identical gate-trigger characteristics, on-state voltage drop, and thermal operating range, ensuring direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can VS-16TTS16STRL-M3 and VS-16TTS16STRR-M3 be used interchangeably with VS-16TTS16STRLPBF?

A: Yes. Both substitute parts meet all electrical specifications of the original part. They share identical voltage ratings (1.6 kV off-state, 1.4 V on-state), current ratings (16 A RMS), gate-trigger parameters (2 V / 60 mA), and operating temperature range (-40°C to 125°C). The TO-263AB package and surface mount configuration are identical, enabling direct PCB placement without design modification.

Q: What is the difference between the three part numbers?

A: The primary differences are product status and packaging format. VS-16TTS16STRLPBF is discontinued and supplied in bulk packaging. VS-16TTS16STRL-M3 and VS-16TTS16STRR-M3 are active products supplied in tape & reel format, which is standard for high-volume automated assembly. All three share identical electrical specifications and the same base product number (16TTS16).

Q: Are there any compliance or certification differences?

A: All three parts are ROHS3 compliant. VS-16TTS16STRLPBF and VS-16TTS16STRL-M3 are both REACH Unaffected. Moisture sensitivity level is 1 (Unlimited) for the original and first substitute. All parts carry EAR99 ECCN classification and the same HTSUS code (8541.30.0080).

Q: Does the improved surge current rating of the substitutes affect circuit design?

A: The substitute parts feature a higher non-repetitive surge current rating (200 A @ 50Hz vs. 170 A @ 50Hz). This represents an enhanced performance margin and does not require circuit redesign. Existing designs using the original part will operate within the substitute's specifications.

Q: What packaging format should I specify for new production?

A: For automated assembly processes, specify tape & reel (TR) packaging. Both VS-16TTS16STRL-M3 and VS-16TTS16STRR-M3 are available in this format. Tape & reel is the standard supply format for surface mount components and is compatible with pick-and-place assembly equipment.
