PVY116-TPBF Solid State Relay: Equivalent & Substitute Parts

Part Overview

The PVY116-TPBF is a Surface Mount Solid State Relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with 1 Form A circuit. This component operates with a 1.2VDC input signal and supports load voltages from 0V to 40V at a maximum load current of 250mA. The part is classified as Obsolete, making identification of active equivalent alternatives essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVY116-TPBF is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit Configuration: SPST-NO (1 Form A)
• Package / Case: 4-SOP (0.173", 4.40mm)
• Mounting Type: Surface Mount
• Termination Style: Gull Wing
• Load Voltage Range: 0V ~ 40V
• Output Type: AC, DC compatibility

Acceptable Variation Parameters:

• Input Voltage: Substitute parts may operate at different input voltages (1.14VDC vs. 1.2VDC) provided the control circuit can supply the required signal level
• Load Current: Substitute parts rated at 120mA are acceptable for applications requiring ≤120mA; applications requiring >120mA and ≤250mA cannot use these substitutes
• On-State Resistance: Substitute parts with higher on-state resistance (12.5 Ohms vs. 4.4 Ohms) result in increased power dissipation and voltage drop across the relay

The three substitute parts (AQY221N2S, AQY221N2SX, AQY221N2SZ) are manufactured by Panasonic Electric Works from the PhotoMOS™ AQY series and share identical electrical specifications. They differ only in packaging format (Tube vs. Tape & Reel) and product status (all Active).

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The AQY221N2S, AQY221N2SX, and AQY221N2SZ are direct functional substitutes for the PVY116-TPBF in applications where load current does not exceed 120mA. All substitute parts maintain identical load voltage range (0V ~ 40V), circuit configuration (SPST-NO), and physical package dimensions (4-SOP, 0.173", 4.40mm).

Status and Compliance Advantages:

All three substitute parts carry Active product status, ensuring long-term availability and continued manufacturing support. The Panasonic PhotoMOS™ AQY series components are ROHS3 Compliant, providing enhanced environmental compliance compared to the obsolete PVY116-TPBF. Both the main part and substitutes maintain REACH Unaffected and EAR99 export classification status.

Load Current Limitation:

Applications requiring load currents between 120mA and 250mA cannot use the AQY221N2S, AQY221N2SX, or AQY221N2SZ substitutes. In such cases, alternative relay solutions with higher current ratings must be evaluated.

Input Voltage Consideration:

The substitute parts operate at 1.14VDC input versus the main part's 1.2VDC. This 0.06VDC difference is within typical control circuit tolerances and does not prevent substitution in standard applications.

On-State Resistance Impact:

The substitute parts exhibit 12.5 Ohms maximum on-state resistance compared to 4.4 Ohms for the main part. This results in approximately 2.8 times higher voltage drop and power dissipation across the relay contacts. Thermal management and voltage drop calculations must be performed for applications sensitive to these parameters.

Packaging Format Selection:

AQY221N2S is supplied in Tube packaging, suitable for lower-volume or manual assembly operations. AQY221N2SX and AQY221N2SZ are supplied in Tape & Reel format, optimized for automated pick-and-place assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the AQY221N2S, AQY221N2SX, or AQY221N2SZ be used as direct drop-in replacements for the PVY116-TPBF?

A: Yes, for applications with load currents ≤120mA. All substitute parts share identical package dimensions (4-SOP, 0.173", 4.40mm), mounting type (Surface Mount), and termination style (Gull Wing). Pin-to-pin compatibility is maintained. Applications requiring load currents >120mA cannot use these substitutes.

Q: What is the impact of the higher on-state resistance in the substitute parts?

A: The AQY221N2S, AQY221N2SX, and AQY221N2SZ have 12.5 Ohms maximum on-state resistance versus 4.4 Ohms for the PVY116-TPBF. For a 120mA load, this results in 1.5V voltage drop across the substitute relay compared to 0.528V for the main part. Power dissipation increases from 63.36mW to 180mW. Applications with tight voltage budgets or thermal constraints must account for this difference.

Q: Are the three substitute part numbers (AQY221N2S, AQY221N2SX, AQY221N2SZ) electrically identical?

A: Yes. All three parts are electrically identical. The differences are limited to packaging format: AQY221N2S is supplied in Tube packaging, while AQY221N2SX and AQY221N2SZ are supplied in Tape & Reel format. Selection between these three should be based on assembly process requirements and inventory management practices.

Q: Does the 0.06VDC difference in input voltage (1.14VDC vs. 1.2VDC) affect substitution?

A: No. The input voltage difference is within standard control circuit tolerances. Provided the control circuit can supply 1.14VDC or higher, the substitute parts will operate correctly. Most digital logic outputs and standard signal sources exceed this threshold.

Q: What compliance certifications apply to the substitute parts?

A: The AQY221N2S, AQY221N2SX, and AQY221N2SZ are ROHS3 Compliant and REACH Unaffected. Both the main part and substitutes carry EAR99 export classification. All parts maintain identical HTSUS code (8536.41.0030).

Q: Can I use the substitute parts in applications requiring AC or DC output switching?

A: Yes. The substitute parts support AC, DC (RF) output type, which encompasses both AC and DC load switching. The main part supports AC, DC output type. Both configurations are compatible with standard relay switching applications.

Q: What should I consider when selecting between Tube and Tape & Reel packaging?

A: Tube packaging (AQY221N2S) is suitable for manual assembly, prototyping, and lower-volume production. Tape & Reel packaging (AQY221N2SX, AQY221N2SZ) is optimized for automated pick-and-place assembly and high-volume manufacturing. Selection depends on production volume, assembly equipment, and inventory management requirements.
