Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS7141E-1A-A is determined by strict equivalence of electrical and mechanical parameters. All qualifying substitute parts must maintain:

• Identical circuit configuration (SPST-NO, 1 Form A)
• Identical package type (6-DIP, 0.300" / 7.62mm)
• Identical through-hole mounting interface
• Load voltage range covering 0–400 V
• Load current equal to or exceeding 120 mA
• Input voltage compatible with 1.2 VDC operation
• On-state resistance at or below 50 Ohms
• Output type supporting both AC and DC loads
• Identical PC Pin termination

The substitute parts identified—AQV214E and PVT412LPBF—meet all specified electrical and mechanical criteria, providing direct functional equivalence in the same physical form factor.

Engineering Selection Recommendations

AQV214E (Panasonic Electric Works)

This substitute offers complete functional equivalence with active product status and ROHS3 compliance. Input voltage specification (1.14 VDC) is within normal operating tolerance relative to the 1.2 VDC requirement. On-state resistance matches the original specification at 50 Ohms maximum. The PhotoMOS™ AQV series demonstrates established reliability in solid-state relay applications. Current inventory availability is 1620 units.

PVT412LPBF (Infineon Technologies)

This alternative provides enhanced performance characteristics with a reduced maximum on-state resistance of 35 Ohms, delivering improved power efficiency compared to the original 50 Ohms specification. Input voltage and all other critical parameters match the PS7141E-1A-A. The part carries ROHS3 compliance and active product status. Current inventory availability is 10200 units, supporting immediate deployment in production environments.

Both substitutes satisfy all mandatory electrical and mechanical equivalence criteria, with AQV214E providing specification matching and PVT412LPBF offering performance enhancement through lower on-state resistance.

Frequently Asked Questions (FAQ)

Q: Can I substitute PS7141E-1A-A with AQV214E or PVT412LPBF on existing circuit boards?

A: Yes. Both substitute parts share identical 6-DIP package dimensions and through-hole PC pin termination, enabling direct socket replacement without circuit board redesign.

Q: What is the difference in input voltage specifications between the three parts?

A: PS7141E-1A-A operates at 1.2 VDC input. AQV214E specifies 1.14 VDC, and PVT412LPBF specifies 1.2 VDC. Both substitutes operate within normal control circuit tolerance bands and are functionally compatible.

Q: How do on-state resistance differences affect circuit performance?

A: PS7141E-1A-A and AQV214E both specify 50 Ohms maximum on-state resistance. PVT412LPBF specifies 35 Ohms, reducing heat dissipation in switching applications. Designs rated for 50 Ohms accept the lower resistance without modification.

Q: Are AQV214E and PVT412LPBF certified for the same applications as PS7141E-1A-A?

A: Both substitutes carry equivalent certifications (ROHS3 compliance, EAR99 ECCN classification, identical HTSUS code) and support identical AC/DC output load types across the 0–400 V voltage range.

Q: What is the availability status of these substitute parts?

A: AQV214E is active (Panasonic Electric Works) with 1620 units in stock. PVT412LPBF is active (Infineon Technologies) with 10200 units in stock. PS7141E-1A-A is obsolete and no longer manufactured.
