IR21716S Equivalent & Substitute Parts

Part Overview

The IR21716S is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT configurations in synchronous applications. This device operates with a supply voltage range of 13V to 20V and supports a maximum bootstrap voltage of 600V, making it suitable for power management applications requiring dual-channel gate driving. The IR21716S is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement.

Substitute Part Grouping Explanation

The IR2175SPBF has been identified as a manufacturer-recommended substitute for the IR21716S. However, substitution analysis reveals a critical functional divergence that requires engineering evaluation.

The IR21716S operates as a half-bridge gate driver with dual-channel IGBT gate driving capability, characterized by a 13V–20V supply voltage range and 600V bootstrap voltage support. The IR2175SPBF, conversely, functions as a current sense regulator with 20mA output capability and ±0.5% accuracy specification. While both devices are manufactured by Infineon Technologies and share identical HTSUS and ECCN classifications, they serve fundamentally different circuit functions.

Substitution feasibility is determined by the following parameters:

• Manufacturer alignment (Infineon Technologies)
• Supply voltage compatibility (9.5V–20V for IR2175SPBF overlaps with 13V–20V requirement)
• Operating temperature range (IR2175SPBF: -40°C to 125°C; IR21716S: -40°C to 150°C)
• Surface mount packaging format
• Regulatory compliance status

Parameter Comparison

Engineering Selection Recommendations

Selection between IR21716S and IR2175SPBF must account for functional application requirements and regulatory constraints.

The IR21716S is classified as obsolete and RoHS non-compliant. The IR2175SPBF offers improved regulatory compliance through ROHS3 certification, addressing modern procurement standards. However, the IR2175SPBF operates with a reduced maximum junction temperature of 125°C compared to the IR21716S specification of 150°C, which may impact thermal margin in high-temperature applications.

Both devices maintain identical export control classifications (EAR99) and tariff codes (8542.39.0001), ensuring equivalent regulatory treatment. The IR2175SPBF demonstrates superior moisture handling through ROHS3 compliance, though it requires stricter storage conditions (MSL 2, 1-year shelf life) versus the IR21716S unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can IR2175SPBF directly replace IR21716S in existing designs?

A: Direct replacement requires functional verification. While both devices are Infineon Technologies products with compatible supply voltage ranges and surface mount packaging, the IR2175SPBF operates as a current sense regulator rather than a gate driver. Circuit topology and application requirements must be evaluated to confirm functional equivalence.

Q: What is the temperature operating range difference?

A: The IR21716S supports -40°C to 150°C junction temperature operation, while IR2175SPBF is rated to -40°C to 125°C. Applications requiring operation above 125°C junction temperature cannot use IR2175SPBF as a substitute.

Q: Does IR2175SPBF meet modern RoHS requirements?

A: Yes. IR2175SPBF carries ROHS3 compliance certification, whereas IR21716S is RoHS non-compliant. This represents an improvement for procurement into regulated markets.

Q: What are the packaging differences?

A: IR21716S is specified as 16SOIC package format. IR2175SPBF is supplied in 8-SOIC (0.154", 3.90mm width) package. Physical footprint differences require PCB layout verification before substitution.

Q: Are there supply voltage compatibility concerns?

A: IR2175SPBF supply voltage range (9.5V–20V) encompasses the IR21716S requirement (13V–20V). No voltage compatibility issues exist within specified operating ranges.

Q: What moisture sensitivity considerations apply?

A: IR21716S carries MSL 1 (unlimited shelf life). IR2175SPBF carries MSL 2 (1-year shelf life), requiring stricter storage and handling protocols to maintain component reliability.
