Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1850480000 is determined by the following critical parameters:

• Pitch and Position Count: Substitute parts must maintain 0.300" (7.62mm) pitch with 5 positions per level to ensure PCB footprint compatibility
• Mounting Orientation: Vertical with board orientation is required for mechanical fit
• Mounting Type: Through-hole mounting must be preserved for PCB assembly compatibility
• Wire Termination Method: Screw-clamp termination is the functional requirement
• Operating Temperature Range: Must support -50°C ~ 100°C minimum
• Compliance Standards: RoHS compliance and REACH unaffected status are mandatory

The substitute part 1786540000 meets all critical substitution criteria. This part belongs to the TOP4GS series, which represents an active product line offering enhanced electrical specifications while maintaining mechanical and thermal compatibility with the obsolete 1850480000.

Parameter Comparison

Engineering Selection Recommendations

The 1786540000 is the qualified substitute for the obsolete 1850480000. Selection is based on the following engineering factors:

Product Status: The 1850480000 is obsolete, while the 1786540000 is active. Active product status ensures ongoing availability, technical support, and manufacturing continuity.

Compliance Alignment: Both parts maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements for current and future applications.

Mechanical Compatibility: Identical pitch (7.62mm), position count (5), mounting orientation (vertical with board), and through-hole mounting type ensure direct PCB footprint compatibility without layout modifications.

Electrical Enhancement: The 1786540000 provides specified current (30 A) and voltage (300 V) ratings, whereas the main part does not list these values. This represents an upgrade in electrical specification documentation.

Wire Gauge Expansion: The substitute accepts 10-26 AWG wire, compared to 14-26 AWG for the main part, providing broader wire size compatibility.

Thermal Consistency: Both parts operate across -50°C ~ 100°C, maintaining thermal performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1786540000 be used as a direct replacement for the 1850480000 on existing PCBs?

A: Yes. Both parts share identical pitch (7.62mm), position count (5), mounting orientation (vertical with board), and through-hole mounting type. PCB footprints are compatible without modification.

Q: What is the difference in wire gauge acceptance between these parts?

A: The 1850480000 accepts 14-26 AWG wire, while the 1786540000 accepts 10-26 AWG. The substitute supports a wider range, including heavier gauge conductors.

Q: Are there differences in screw specifications?

A: Yes. The 1850480000 uses M2.5 screws with 0.4-0.5 Nm torque specification. The 1786540000 uses M3 screws with 0.5-0.6 Nm torque specification. Termination procedures must follow the respective datasheets.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 1850480000 and 1786540000 are RoHS compliant and REACH unaffected, satisfying current regulatory standards.

Q: What is the contact material difference?

A: The 1850480000 uses copper alloy with tin plating. The 1786540000 uses electrolytic copper with tin plating. Both provide tin-plated contact surfaces suitable for screw-clamp termination.

Q: Why is the 1850480000 listed as obsolete?

A: Product obsolescence reflects manufacturing discontinuation. The 1786540000 from the TOP4GS series represents the active product line continuation with enhanced electrical specifications and broader wire gauge support.
