Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT78051 is determined by strict equivalence across the following critical parameters:

• Number of Positions: 11 (exact match required)
• Mounting Type: Free Hanging (exact match required)
• Termination Style: Screw Terminal (exact match required)
• Type: Socket (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: Equivalent or higher compliance level acceptable

The substitute part P3GA-11 manufactured by Omron Automation and Safety meets all mandatory electrical and mechanical parameters for direct substitution. Both components share identical functional specifications across position count, mounting configuration, and termination method, enabling seamless integration into existing applications.

Parameter Comparison

Engineering Selection Recommendations

The P3GA-11 is the qualified substitute for the AT78051. Selection rationale is based on the following factors:

Functional Equivalence: Both components are 11-position free hanging relay sockets with screw terminal connections. Electrical and mechanical specifications are identical, ensuring direct compatibility in existing circuit designs.

Product Status: The AT78051 is obsolete, while the P3GA-11 is active. Selection of the active alternative ensures long-term availability and supply chain reliability.

Compliance: The P3GA-11 meets ROHS3 compliance, which exceeds the RoHS compliance of the AT78051. Both components maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Inventory Availability: The P3GA-11 is currently available with 950 units in stock, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the P3GA-11 be used as a direct replacement for the AT78051?

A: Yes. Both components share identical specifications for number of positions (11), mounting type (free hanging), and termination style (screw terminal). Direct substitution is supported without circuit modification.

Q: What is the significance of the obsolete status of the AT78051?

A: Obsolete status indicates the manufacturer has discontinued production. The P3GA-11 is an active product, ensuring continued availability for future procurement and system maintenance.

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

A: The P3GA-11 carries ROHS3 compliance, which is equivalent to or exceeds RoHS compliance. Both components maintain identical MSL 1 (Unlimited) ratings. No compliance barriers exist for substitution.

Q: Does packaging differ between the AT78051 and P3GA-11?

A: Both components are supplied in bulk packaging. No packaging conversion is required for substitution.

Q: What parameters must match for a relay socket to be considered equivalent?

A: For 11-position free hanging relay sockets with screw terminals, the following parameters must match: number of positions, mounting type, termination style, and moisture sensitivity level. RoHS compliance may be equivalent or higher.
