Frequently Asked Questions (FAQ)

Q: Can the 1950650000 be used as a direct replacement for the 1894690000 in existing assemblies?

A: Yes. Both parts share identical mechanical specifications (9 positions, 5.08mm pitch, 270° wire entry orientation), enabling direct substitution without modification to mating connectors or installation geometry.

Q: What are the key electrical differences between the original and substitute parts?

A: The original part specifications are not fully documented in available data. The substitute part (1950650000) provides documented electrical ratings: 23A at 400V (IEC) and 20A at 300V (UL), with wire gauge support of 12-30 AWG (0.2-4mm²).

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS Compliance and REACH Unaffected status. The substitute part includes additional documentation of UL94 V-0 material flammability rating and operating temperature range (-50°C to 100°C).

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates continued manufacturer production, documented technical support, and supply chain availability. This ensures long-term component sourcing for maintenance and new system designs.

Q: Are there packaging differences between the two parts?

A: The original part packaging is not specified. The substitute part (1950650000) is supplied in Bulk packaging format.

Q: What termination method does the substitute part use?

A: The 1950650000 uses screw-clamping termination with a tension sleeve mechanism, specified for M2.5 screws with torque range of 0.4-0.5 Nm (4.6-4.4 Lb-In).
