Key Parameters

Substitute Part Grouping Explanation

The C3900BA qualifies as a substitute for the SX0794 based on the following critical parameters:

Circuit configuration match: Both components are SPST switches with identical on-off switching function, ensuring functional equivalence in control applications.

Mounting compatibility: Both utilize panel mount installation with circular cutout dimensions (SX0794: 12.00mm, C3900BA: 12.70mm), permitting installation in standard panel configurations with minor mechanical adaptation.

Electrical performance: The C3900BA provides higher current ratings (20A AC, 14A DC) and voltage ratings (125V AC, 36V DC) compared to the SX0794 (10A, 250V AC, 28V DC), establishing it as a capable replacement in applications operating within the original part's electrical envelope.

Regulatory compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The C3900BA represents an active product alternative to the obsolete SX0794, with current manufacturing availability and equivalent regulatory compliance. Selection of the C3900BA requires consideration of the following factors:

Termination interface: The SX0794 employs screw terminal connections while the C3900BA utilizes quick connect terminals. System integration must accommodate this termination style difference through appropriate connector adaptation or wiring methodology.

Panel cutout accommodation: The C3900BA panel cutout diameter of 12.70mm exceeds the SX0794 specification of 12.00mm. Existing panel installations designed for the SX0794 may require mechanical modification to accommodate the larger cutout dimension.

Electrical rating differential: The C3900BA provides enhanced current and voltage ratings within the AC domain (20A at 125V AC versus 10A at 250V AC). Applications must verify that the substitute part's electrical characteristics align with system requirements.

Active product status: The C3900BA maintains active manufacturing status with documented inventory availability, ensuring long-term supply chain continuity compared to the obsolete SX0794.

Frequently Asked Questions (FAQ)

Q: Can the C3900BA directly replace the SX0794 without modification?

A: Functional replacement is possible; however, termination style and panel cutout dimensions differ. Screw terminal connections must be adapted to quick connect terminals, and panel installations may require enlargement of the cutout from 12.00mm to 12.70mm diameter.

Q: Are the electrical ratings of the C3900BA suitable for SX0794 applications?

A: The C3900BA provides higher current capacity (20A AC, 14A DC) and DC voltage rating (36V). Applications operating within the original SX0794 electrical envelope (10A, 250V AC, 28V DC) will operate within the substitute part's rated specifications.

Q: What is the significance of the different AC voltage ratings?

A: The SX0794 is rated for 250V AC while the C3900BA is rated for 125V AC. Applications requiring 250V AC operation must verify that system voltage does not exceed the C3900BA's 125V AC maximum rating.

Q: Does the C3900BA meet the same regulatory requirements as the SX0794?

A: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent environmental and regulatory standards.

Q: What packaging considerations apply to the C3900BA?

A: The C3900BA is supplied in bulk packaging, differing from the SX0794 packaging specification. Procurement quantities and handling procedures should reflect bulk packaging requirements.
