PVT312L Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PVT312L is a solid state relay (SSR) manufactured by Infineon Technologies, configured as a SPST-NO (Single Pole Single Throw - Normally Open) switching device. This 6-DIP through-hole component is designed for AC and DC load switching applications with a maximum load current of 170 mA across a voltage range of 0 V to 250 V. The PVT312L is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance, repair, and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVT312L is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Voltage Specifications: Input 1.2 VDC, Load 0 V ~ 250 V
• Load Current Rating: 170 mA maximum
• On-State Resistance: 15 Ohms maximum
• Package / Case: 6-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole with PC Pin termination

Two substitute parts meet these electrical and mechanical requirements while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

PVT312LPBF is the primary substitute for PVT312L. This part is manufactured by Infineon Technologies, the original equipment manufacturer, and maintains identical electrical and mechanical specifications. The PVT312LPBF carries Active product status and ROHS3 compliance, addressing the regulatory limitations of the obsolete PVT312L. The packaging format (Tube) differs from the original, but electrical performance and PCB integration remain equivalent.

LCA127L is an alternative substitute manufactured by IXYS Integrated Circuits Division. This part meets all electrical and mechanical requirements and carries Active product status with ROHS3 compliance. The LCA127L employs OptoMOS® technology within the same 6-DIP package footprint, providing functional equivalence for direct board-level substitution.

Both substitute parts eliminate the compliance and availability constraints associated with the obsolete PVT312L while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can PVT312LPBF be used as a direct replacement for PVT312L?

A: Yes. PVT312LPBF is electrically and mechanically equivalent to PVT312L. Both parts share identical circuit configuration (SPST-NO), voltage ratings (1.2 VDC input, 0-250 V load), current rating (170 mA), on-state resistance (15 Ohms maximum), and 6-DIP package footprint. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between PVT312L and LCA127L?

A: Both parts are functionally equivalent across all specified electrical and mechanical parameters. The primary differences are manufacturer (Infineon Technologies vs. IXYS Integrated Circuits Division) and internal technology (HEXFET® vs. OptoMOS®). Both are Active products with ROHS3 compliance. Selection between these substitutes depends on supply chain availability and design preference.

Q: Are the package dimensions identical across all three parts?

A: Yes. PVT312L, PVT312LPBF, and LCA127L all use the 6-DIP (0.300", 7.62mm) package with PC Pin termination. Through-hole mounting compatibility is maintained across all three parts.

Q: Does the packaging format (Tube vs. original) affect electrical performance?

A: No. Packaging format (Tube) is a supply and handling specification only. It does not affect electrical characteristics, performance, or PCB integration of PVT312LPBF.

Q: Are there any compliance differences between the substitute parts?

A: PVT312L is RoHS non-compliant. Both PVT312LPBF and LCA127L are ROHS3 compliant. All three parts maintain identical REACH Unaffected, ECCN EAR99, and HTSUS 8536.41.0030 classifications.
