PVY117 Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The Infineon PVY117 is a surface mount solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 470 mA load current at 0–40 V output voltage. This component operates with a 1.2 VDC input and features a 4-SOP package with gull wing termination. The PVY117 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Panasonic PhotoMOS™ AQY series relays provide direct functional equivalents with active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVY117 is based on the following critical parameters that must remain compatible:

• Circuit Configuration: SPST-NO (1 Form A) topology required for identical switching function
• Package / Case: 4-SOP (0.173", 4.40mm) with gull wing termination for PCB layout compatibility
• Voltage - Load Range: 0 V ~ 40 V maximum operating range
• Output Type: AC and DC switching capability
• Mounting Type: Surface mount for automated assembly compatibility

The Panasonic AQY221N2S, AQY221N2SX, and AQY221N2SZ variants meet all substitution criteria. These parts share identical package geometry, circuit configuration, and load voltage specifications. Differences in load current rating (120 mA vs. 470 mA) and on-state resistance represent design trade-offs; applications requiring the full 470 mA capacity must be evaluated for compatibility with the 120 mA substitute rating.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The PVY117 is obsolete. All three Panasonic AQY221 variants (AQY221N2S, AQY221N2SX, AQY221N2SZ) maintain active product status, ensuring long-term availability and supply chain stability.

Compliance: The Panasonic substitutes are ROHS3 compliant, whereas the PVY117 is RoHS non-compliant. For applications subject to RoHS regulations, the AQY221 series satisfies compliance requirements.

Load Current Derating: The substitute parts are rated for 120 mA maximum load current compared to the PVY117's 470 mA rating. Circuit designs must operate within the 120 mA limit or employ alternative switching architectures.

Packaging Selection: AQY221N2S is supplied in tube packaging; AQY221N2SX and AQY221N2SZ are supplied in tape & reel format. Packaging selection depends on assembly process requirements and order quantities.

Frequently Asked Questions (FAQ)

Q: Can AQY221N2S, AQY221N2SX, and AQY221N2SZ be used interchangeably?

A: Yes, these three part numbers are functionally identical. They differ only in packaging format: AQY221N2S uses tube packaging, while AQY221N2SX and AQY221N2SZ use tape & reel. Electrical specifications, circuit configuration, and package geometry are identical across all three variants.

Q: What is the primary limitation when substituting PVY117 with AQY221 series relays?

A: The load current rating is reduced from 470 mA to 120 mA. Applications requiring higher switching currents must be redesigned or use alternative relay architectures.

Q: Are the input voltage specifications compatible?

A: The PVY117 requires 1.2 VDC input, while AQY221 variants require 1.14 VDC. This 0.06 VDC difference is within typical circuit tolerance margins and does not prevent substitution in standard applications.

Q: Do the substitute parts support both AC and DC output switching?

A: Yes. All AQY221 variants support AC and DC output switching with RF capability, matching the PVY117's AC/DC output type specification.

Q: Is PCB layout modification required when substituting PVY117 with AQY221 series?

A: No. Both the PVY117 and all AQY221 variants use identical 4-SOP (0.173", 4.40mm) packages with gull wing termination. PCB footprints and land patterns are compatible without modification.
