PS7113-1A Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The PS7113-1A is a solid state relay (SSR) manufactured by CEL, configured as a single-pole single-throw normally open (SPST-NO) device in a 6-DIP through-hole package. This component operates with a 1.2VDC input signal and switches loads up to 350mA across 0–100V AC or DC output ranges, with a maximum on-state resistance of 2.5 Ohms.

The PS7113-1A is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS7113-1A is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Package type: 6-DIP (0.300", 7.62mm) through-hole
• Termination style: PC Pin
• Output type: AC and DC capability
• Load voltage range: 0–100V (or compatible subset)
• Load current: 350mA or greater
• On-state resistance: 2.5 Ohms or lower

Acceptable Substitution Logic: Parts meeting all primary criteria are classified as direct substitutes. Parts with reduced load voltage ranges (0–60V) or lower current ratings are classified as conditional substitutes, suitable only when application requirements fall within their specified operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Full Compatibility):

The AQV255 (Panasonic Electric Works) is the primary direct substitute for the PS7113-1A. Both parts share identical load voltage range (0–100V), load current (350mA), and on-state resistance (2.5 Ohms). The AQV255 is currently in active production status with ROHS3 compliance, providing superior supply chain availability and regulatory alignment compared to the obsolete PS7113-1A.

The PLA134 (IXYS Integrated Circuits Division) is a secondary direct substitute, matching all critical electrical parameters. However, PLA134 is also classified as obsolete, limiting its utility for new designs or long-term supply assurance.

Conditional Substitutes (Load Voltage Restricted to 0–60V):

The AQV252 and AQV202 are suitable substitutes only for applications where the load voltage requirement does not exceed 60V. Both parts offer 400mA load current capability and 1.4 Ohm on-state resistance, providing improved performance in reduced-voltage applications. AQV252 operates with 1.14VDC input; AQV202 requires 2.3VDC input.

The AQV212 is applicable for 0–60V load voltage applications requiring 550mA current capacity, with on-state resistance matching the PS7113-1A at 2.5 Ohms.

Not Recommended:

The AQV102 is not recommended as a substitute due to DC-only output capability (the PS7113-1A supports both AC and DC) and reduced load voltage range (0–60V maximum).

Frequently Asked Questions (FAQ)

Q: Can the AQV255 replace the PS7113-1A in all applications?

A: Yes. The AQV255 meets or exceeds all electrical specifications of the PS7113-1A: identical load voltage range (0–100V), load current (350mA), and on-state resistance (2.5 Ohms). Both support AC and DC output. The 6-DIP package and PC pin termination are identical. The AQV255 is actively manufactured and RoHS3 compliant.

Q: Why do some substitute parts have a 0–60V load voltage limit instead of 0–100V?

A: Load voltage rating is a fundamental design parameter that determines the maximum voltage the relay output can safely switch. Parts rated for 0–60V cannot be used in applications requiring 0–100V switching capability. These parts are suitable only when application requirements fall entirely within the 0–60V range.

Q: Is the input voltage difference between PS7113-1A (1.2VDC) and AQV255 (1.14VDC) significant?

A: No. The 0.06VDC difference is negligible for practical circuit design. Both values fall within standard logic signal levels and do not affect substitution compatibility.

Q: Can I use AQV202 instead of AQV252 if both are rated 0–60V and 400mA?

A: Both parts are electrically equivalent within the 0–60V load voltage range. The primary difference is input voltage: AQV202 requires 2.3VDC while AQV252 requires 1.14VDC. Select based on your available control signal voltage.

Q: Why is PLA134 listed as a substitute if it is obsolete?

A: PLA134 is included for reference and historical compatibility documentation. It meets all electrical specifications of the PS7113-1A. However, obsolete status limits supply availability. AQV255 is the recommended active-production alternative.

Q: Are all substitute parts available in the same 6-DIP package?

A: Yes. All listed substitute parts use the 6-DIP (0.300", 7.62mm) through-hole package with PC pin termination, ensuring mechanical and electrical compatibility with existing PCB designs.

Q: What does RoHS3 compliance mean for component selection?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. For new designs or regulated applications, RoHS3-compliant parts (such as AQV255) are required. The PS7113-1A is RoHS non-compliant and should not be used in new designs subject to RoHS requirements.
