Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1877460000 is the direct substitute for the obsolete 1878000000 terminal block header. Both components maintain identical electrical specifications, mechanical dimensions, and compliance certifications across IEC and UL standards.

The 1877460000 offers the advantage of active product status, ensuring continued availability and manufacturing support. The contact tail length differs between the two parts (0.059" versus 0.126"), which may require PCB layout verification for through-hole solder joint clearance and board-level spacing.

Both parts carry RoHS compliance and REACH unaffected status, meeting environmental regulatory requirements. The UL94 V-0 flammability rating is maintained across both components.

Frequently Asked Questions (FAQ)

Q: Can the 1877460000 be used as a direct replacement for the 1878000000?

A: Yes. Both components share identical electrical ratings (27.5A at 400V IEC, 18.5A at 300V UL), mechanical configuration (6 positions, 5.08mm pitch, 90° orientation), and compliance certifications. The primary difference is product status and contact tail length.

Q: What is the significance of the different contact tail lengths?

A: The 1878000000 has a contact tail length of 0.059" (1.50mm), while the 1877460000 has 0.126" (3.20mm). This difference affects solder joint depth and PCB hole engagement. Verify your PCB design accommodates the longer tail length of the substitute part.

Q: Are there packaging differences between these parts?

A: The 1878000000 packaging is not specified, while the 1877460000 is supplied in bulk packaging. Confirm bulk packaging meets your procurement and handling requirements.

Q: Do both parts meet RoHS and REACH compliance?

A: Yes. Both the 1878000000 and 1877460000 are RoHS compliant and REACH unaffected, meeting current environmental standards.

Q: What is the operating temperature range for these terminal blocks?

A: Both components operate across -50°C to 100°C, suitable for industrial and commercial applications within this thermal envelope.
