Substitute Part Grouping Explanation

Substitution of the obsolete 1-435704-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must maintain identical specifications in the following areas:

Electrical Characteristics: 12-position programmable circuit configuration with breakable shunt actuator functionality

Mechanical Compatibility: Through-hole mounting with 0.100" (2.54mm) pitch, PC pin termination, and 0.079" (2.00mm) height above board to ensure PCB layout compatibility

Physical Dimensions: 1.200" (30.48mm) length and flush, recessed actuator level for form-factor consistency

Material Specifications: Copper alloy contacts with tin finish and thermoplastic body material

Environmental Performance: Operating temperature range of -55°C to 105°C and washable construction

The substitute part 1-1825190-0 satisfies all these parameters without deviation, establishing direct functional and mechanical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1-1825190-0 is the direct substitute for the obsolete 1-435704-2. All electrical and mechanical parameters are identical, ensuring drop-in compatibility in existing PCB designs and applications.

Product Status Advantage: The 1-1825190-0 maintains active production status, providing assured long-term availability and supply chain continuity compared to the obsolete 1-435704-2.

Regulatory Compliance Enhancement: The 1-1825190-0 achieves ROHS3 compliance, whereas the 1-435704-2 is RoHS non-compliant. This upgrade supports modern regulatory requirements and environmental standards.

Moisture Sensitivity Classification: The 1-1825190-0 carries MSL 1 (Unlimited) rating, indicating superior moisture handling characteristics compared to the 1-435704-2, which lists MSL as Not Applicable.

Packaging Consideration: The 1-1825190-0 is supplied in tube packaging, which differs from the original part's packaging specification. Tube packaging is standard for active production components and does not affect functional or mechanical compatibility.

Both components share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, and both maintain REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825190-0 be used as a direct replacement for the 1-435704-2 in existing designs?

A: Yes. The 1-1825190-0 is electrically and mechanically equivalent to the 1-435704-2 across all specified parameters, including pin configuration, pitch, height, actuator type, and operating temperature range. No design modifications are required.

Q: What is the primary reason for substitution?

A: The 1-435704-2 is obsolete and no longer manufactured. The 1-1825190-0 is the active production equivalent from the same manufacturer and series, ensuring continued component availability.

Q: Does the packaging difference affect compatibility?

A: No. The 1-1825190-0 is supplied in tube packaging, which is a standard packaging format for active production components. The individual component specifications and form factor remain identical to the original part.

Q: Are there compliance differences between the two parts?

A: Yes. The 1-1825190-0 is ROHS3 compliant and carries MSL 1 (Unlimited) rating, whereas the 1-435704-2 is RoHS non-compliant with MSL listed as Not Applicable. These improvements in the substitute part support modern regulatory and environmental standards.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by equivalence in 12-position programmable circuit configuration, breakable shunt actuator, through-hole mounting with 0.100" pitch, PC pin termination, 0.079" height above board, copper alloy tin-finished contacts, thermoplastic body, 1.200" length, and -55°C to 105°C operating temperature range.

Q: Is inventory availability a factor in selecting the substitute?

A: The 1-1825190-0 has significantly higher inventory availability (8,199 pieces) compared to the 1-435704-2 (870 pieces), supporting reliable supply for production and maintenance applications.
