PS7113-1A-A Solid State Relay - Equivalent & Substitute Parts

Part Overview

The PS7113-1A-A is a solid state relay (SSR) with SPST-NO (1 Form A) switching configuration, rated for 350 mA load current at 0-100 V output range with 1.2 VDC input control voltage. The component is housed in a 6-DIP package (0.300", 7.62mm) for through-hole mounting applications. This part is designated as obsolete, making equivalent and substitute parts essential for ongoing design support and maintenance of legacy systems.

• Load current rating: 350 mA
• Output type: AC, DC capability

Mechanical Parameters:

• Package type: 6-DIP (0.300", 7.62mm)
• Mounting: Through Hole
• Termination: PC Pin

The PLA134 (IXYS Integrated Circuits Division) meets all critical electrical and mechanical requirements, providing functional equivalence for direct substitution in applications requiring SPST-NO solid state relay functionality within the specified voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the PS7113-1A-A and PLA134 are classified as obsolete components. The PLA134 maintains full electrical and mechanical compatibility with identical voltage and current specifications. The marginal difference in on-state resistance (3 Ohms vs. 2.5 Ohms maximum) remains within acceptable operational parameters for SPST-NO relay applications in the specified load range.

The PLA134 carries ROHS3 compliance status, whereas the PS7113-1A-A is REACH Affected. Selection between these parts depends on regulatory compliance requirements for target applications and regional deployment standards.

Frequently Asked Questions (FAQ)

Q: Can PLA134 directly replace PS7113-1A-A in existing PCB designs? A: Yes. The PLA134 maintains identical package geometry (6-DIP, 0.300", 7.62mm), pin configuration (PC Pin termination), and electrical specifications (SPST-NO, 1.2 VDC input, 0-100 V output, 350 mA load current). No design modifications are required.

Q: What is the significance of the on-state resistance difference (2.5 Ohms vs. 3 Ohms)? A: Both values fall within typical SSR performance parameters for 350 mA rated applications. The 0.5 Ohm difference produces negligible voltage drop variance across standard load impedances in the 0-100 V operating range.

Q: Are there compliance considerations between these substitutes? A: The PLA134 is ROHS3 compliant, while the PS7113-1A-A is REACH Affected. Applications requiring strict RoHS compliance must use the PLA134. Both components have MSL rating of 1 (Unlimited).

Q: What mounting considerations apply to these parts? A: Both components are through-hole mounted DIP packages suitable for PCB socket installation or direct wave soldering. Pin spacing (0.300", 7.62mm) and PC pin termination are identical.

Q: Why are both parts classified as obsolete? A: Obsolete designation indicates these components are no longer actively manufactured. Substitute sourcing from existing inventory requires consultation with authorized distributors. The PLA134 shows 2409 units in current inventory.
