PVX6012 Equivalent & Substitute Parts

Part Overview

The PVX6012 is a solid-state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switch with 1A load current capacity and 0-280V output voltage range. The device features a 14-DIP package with through-hole mounting and operates on 1.2VDC input.

The PVX6012 is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production support. Substitute parts must maintain compatibility with the original circuit specifications while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitution eligibility for the PVX6012 is determined by the following critical parameters:

Circuit Configuration: Must be SPST-NO (1 Form A) to maintain switching topology
Load Current: Minimum 1A rating required; higher ratings are acceptable
Output Voltage Range: Must support 0-280V minimum; extended ranges are acceptable
Input Voltage: Must be compatible with 1.2VDC control signal
Output Type: Must support both AC and DC operation, or DC operation minimum
Termination Style: PC Pin termination required for PCB compatibility
Mounting Type: Through-hole mounting required for mechanical fit

Substitute parts are grouped into two categories:

Category 1 - Direct Package Equivalent: PVX6012PBF maintains identical electrical specifications and 14-DIP packaging, differing only in RoHS compliance status and product lifecycle designation.

Category 2 - Functional Equivalents with Package Variation: AQG12112, AQZ204, CPC1945Y, CPC1967J, and PS1201 meet all electrical requirements but employ alternative package formats (4-SIP, 8-SIP, or i4-Pac™-4). These require PCB redesign for mechanical accommodation.

Engineering Selection Recommendations

For Direct Replacement (No PCB Redesign)

PVX6012PBF is the only substitute requiring no mechanical modification. It maintains identical electrical specifications and 14-DIP packaging while providing ROHS3 compliance. Selection of PVX6012PBF is appropriate for applications where PCB layout cannot be modified and RoHS compliance is required.

For New Designs and Redesign Scenarios

CPC1967J offers the highest current capacity (1.35A) with extended output voltage range (0-400V), matching the original 1.2VDC input requirement and supporting both AC and DC output types. Active product status and ROHS3 compliance make this suitable for new production. The i4-Pac™-4 isolated package requires PCB redesign.

CPC1945Y and PS1201 provide 1A current capacity with 0-400V output voltage range and active product status. Both require PCB redesign due to 8-SIP packaging. CPC1945Y and PS1201 differ in output type designation (Zero Cross vs. unspecified), which may affect zero-crossing detection behavior in AC applications.

For Current-Limited Applications

AQZ204 is suitable only where load current does not exceed 500mA. The device provides extended output voltage range (0-400V) and active product status with ROHS3 compliance. Input voltage (1.16VDC) is compatible with 1.2VDC control signals.

Not Recommended

AQG12112 operates on 9.6-14.4VDC input, which is incompatible with the original 1.2VDC control signal. Additionally, the output voltage range (75-264V) does not support the full 0V minimum of the original specification. This part is unsuitable as a substitute.

Frequently Asked Questions (FAQ)

Q: Can PVX6012PBF be used as a direct replacement without PCB modification?

A: Yes. PVX6012PBF maintains identical electrical specifications and 14-DIP package dimensions. No PCB redesign is required. The primary difference is ROHS3 compliance status and product lifecycle designation (Not For New Designs).

Q: What is the key limitation of AQZ204 as a substitute?

A: AQZ204 has a maximum load current rating of 500mA, compared to the original 1A specification. It is suitable only for applications where load current does not exceed 500mA.

Q: Why is AQG12112 not recommended as a substitute?

A: AQG12112 requires 9.6-14.4VDC input voltage, which is incompatible with the original 1.2VDC control signal. Additionally, its output voltage range (75-264V) does not support operation below 75V, limiting compatibility with applications requiring lower voltage switching.

Q: What package modifications are required for CPC1967J substitution?

A: CPC1967J uses an i4-Pac™-4 isolated package instead of the original 14-DIP format. PCB redesign is required to accommodate the different pin configuration and footprint. Mechanical mounting and electrical routing must be verified before implementation.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts except PVX6012 (the original obsolete part) carry ROHS3 compliance certification. PVX6012PBF is ROHS3 compliant. AQG12112 is RoHS compliant (earlier standard). All other substitutes are ROHS3 compliant.

Q: What is the difference between AC/DC and AC/Zero Cross output types?

A: AC/DC output types support both alternating and direct current switching without zero-crossing detection. AC/Zero Cross output types incorporate zero-crossing detection, which synchronizes switching to AC voltage zero-crossings, reducing electromagnetic interference and switching stress. Selection depends on application requirements.

Q: Can CPC1945Y and PS1201 be used interchangeably?

A: Both parts share identical electrical specifications (1A load current, 0-400V output, 1.2VDC input) and 8-SIP packaging. The primary difference is output type designation: CPC1945Y specifies AC/Zero Cross, while PS1201 specifies AC/Zero Cross. Both are active products with ROHS3 compliance and can be used interchangeably in applications compatible with zero-crossing detection.
