Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 435704-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 7
• Circuit Type: Programmable
• Actuator Type: Breakable (Shunt)
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Pitch: 0.100" (2.54mm), Full
• Contact Material: Copper Alloy
• Contact Finish: Tin
• Operating Temperature Range: -55°C ~ 105°C

The substitute part TE Connectivity ALCOSWITCH 1825190-6 satisfies all mandatory matching parameters. Both components belong to the TE Connectivity ALCOSWITCH 7600 series and maintain identical mechanical and electrical interface specifications. The primary distinction between these parts is packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1825190-6 serves as a direct functional equivalent to the obsolete 435704-7 model. Both components maintain identical mechanical footprint, electrical interface, and operational specifications within the 7600 series product line.

Compliance Considerations:

The substitute part 1825190-6 achieves ROHS3 compliance, whereas the original 435704-7 is RoHS non-compliant. For applications subject to RoHS regulatory requirements or industry standards mandating lead-free component usage, the 1825190-6 provides compliance alignment. Both parts carry EAR99 export classification and share identical HTSUS commodity codes.

Packaging Distinction:

The 1825190-6 is supplied in tube packaging, compared to the standard packaging of the original part. This packaging difference does not affect component functionality or board-level performance but may influence procurement logistics and inventory management procedures.

Availability and Inventory:

The substitute part 1825190-6 maintains higher current inventory levels (1876 pieces) relative to the original part (933 pieces), supporting procurement continuity for ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1825190-6 be used as a direct replacement for the 435704-7 in existing designs?

A: Yes. The 1825190-6 maintains identical mechanical dimensions, electrical interface specifications, and operational characteristics. No design modifications are required for board-level substitution.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 435704-7 is RoHS non-compliant, while the 1825190-6 is ROHS3 compliant. For applications subject to RoHS directives or customer specifications requiring lead-free components, the 1825190-6 fulfills regulatory requirements. Both parts function identically in circuit operation.

Q: Does the tube packaging of the 1825190-6 affect component performance?

A: No. Packaging format does not influence electrical or mechanical performance. Tube packaging is a procurement and handling specification only.

Q: Are there any differences in operating temperature specifications?

A: No. Both parts operate across the identical temperature range of -55°C to 105°C.

Q: What is the Moisture Sensitivity Level (MSL) difference?

A: The 435704-7 lists MSL as Not Applicable, while the 1825190-6 specifies MSL 1 (Unlimited). MSL 1 indicates no moisture sensitivity restrictions during storage or handling.

Q: Can the 1825190-6 be used in applications originally designed for the 435704-7?

A: Yes. Identical pitch (0.100" / 2.54mm), mounting type (through hole), termination style (PC pin), and all electrical specifications ensure direct functional compatibility.
