PVY117-TPBF Equivalent & Substitute Parts

Part Overview

The PVY117-TPBF is a solid-state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switch in a 4-SOP surface mount package. This component is rated for 470 mA load current at 0–40 V output voltage with a 1.2 VDC input trigger. The product is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PVY117-TPBF are qualified based on the following electrical and mechanical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Package / Case: 4-SOP (0.173", 4.40mm)
• Termination style: Gull Wing
• Output voltage range: 0 V ~ 40 V
• Input voltage compatibility: 1.14 VDC (within acceptable operating range)
• Output type: AC, DC
• Mounting type: Surface Mount

The substitute parts AQY221N2S, AQY221N2SX, and AQY221N2SZ are manufactured by Panasonic Electric Works under the PhotoMOS™ AQY series. All three substitutes maintain identical electrical specifications for load voltage, input voltage, package geometry, and circuit topology. The primary differences are packaging format (Tube vs. Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (AQY221N2S, AQY221N2SX, AQY221N2SZ) are active products from Panasonic Electric Works and carry ROHS3 compliance certification. The PVY117-TPBF is obsolete, making these substitutes the appropriate choice for new designs and production continuity.

Selection between the three substitutes depends on packaging requirements:

• AQY221N2SX and AQY221N2SZ are supplied in Tape & Reel format, matching the original PVY117-TPBF packaging configuration and suitable for automated assembly processes.
• AQY221N2S is supplied in Tube packaging and is appropriate for lower-volume applications or manual assembly workflows.

All three substitutes share identical electrical specifications and are pin-compatible within the 4-SOP package footprint. The load current rating of 120 mA for the substitutes is lower than the original 470 mA specification; applications requiring the full 470 mA load current must be re-evaluated for compatibility.

Frequently Asked Questions (FAQ)

Q: Are the AQY221N2S, AQY221N2SX, and AQY221N2SZ parts electrically interchangeable with the PVY117-TPBF?

A: The parts are pin-compatible and share the same circuit configuration (SPST-NO), package geometry (4-SOP), and load voltage range (0–40 V). However, the load current rating differs: the PVY117-TPBF is rated for 470 mA, while the AQY221 series is rated for 120 mA. Applications must be evaluated to confirm that the 120 mA rating is sufficient for the intended load.

Q: What is the difference between AQY221N2S, AQY221N2SX, and AQY221N2SZ?

A: The three parts are electrically identical. The primary difference is packaging: AQY221N2S is supplied in Tube format, while AQY221N2SX and AQY221N2SZ are supplied in Tape & Reel format. Selection depends on assembly process requirements and volume.

Q: Can I use these substitutes in existing designs without PCB modifications?

A: Yes. All substitute parts use the same 4-SOP package with gull wing termination, matching the footprint of the PVY117-TPBF. No PCB layout changes are required. However, circuit design must account for the reduced load current rating of 120 mA.

Q: What compliance certifications do the substitute parts carry?

A: The AQY221N2S, AQY221N2SX, and AQY221N2SZ parts are ROHS3 compliant and REACH unaffected. Both parts carry the same ECCN (EAR99) and HTSUS (8536.41.0030) classifications as the original PVY117-TPBF.

Q: Why is the on-state resistance of the substitutes higher than the original part?

A: The PVY117-TPBF has a maximum on-state resistance of 950 mOhms, while the AQY221 series has a maximum of 12.5 Ohms. This difference reflects different semiconductor technologies and design approaches between Infineon and Panasonic. Circuit designs must account for this resistance value when calculating voltage drops and power dissipation.
