Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1825190-9 serves as a direct functional equivalent to the 1-435704-0 across all critical electrical and mechanical parameters. Both components are classified as obsolete products within the TE Connectivity 7600 series.

A significant distinction exists in regulatory compliance status: the 1825190-9 achieves ROHS3 compliance, whereas the 1-435704-0 is RoHS non-compliant. For applications subject to RoHS directives or equivalent environmental regulations, the 1825190-9 provides compliance alignment while maintaining functional equivalence.

The 1825190-9 specifies Moisture Sensitivity Level 1 (Unlimited), indicating superior moisture tolerance compared to the 1-435704-0 designation of Not Applicable. This characteristic enhances reliability in humid or moisture-exposed environments.

Both components maintain identical through-hole mounting architecture, pitch specifications, and washability characteristics, ensuring direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1825190-9 replace the 1-435704-0 in existing designs?

A: Yes. The 1825190-9 matches all critical parameters including 10-position programmable configuration, breakable shunt actuator, through-hole mounting, 0.100" pitch, tin contact finish, and operating temperature range. Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between these two parts?

A: The 1825190-9 achieves ROHS3 compliance while the 1-435704-0 is RoHS non-compliant. The 1825190-9 also specifies Moisture Sensitivity Level 1 (Unlimited) versus Not Applicable for the original part. Both are functionally equivalent.
