Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 3-435802-8 is determined by the following critical parameters: circuit configuration (SPST), number of positions (8), mounting type (through hole), and pitch (0.100" / 2.54mm). These parameters establish functional compatibility at the board level.

Substitute parts are grouped into two categories:

Direct Equivalent: Parts maintaining identical actuator type (piano) and actuator level (flush, recessed) with matching electrical circuit configuration.

Functional Equivalents: Parts with alternative actuator types (slide standard) that maintain SPST circuit configuration, 8-position count, through-hole mounting, and standard pitch. These parts provide functional substitution with different user interface characteristics.

The following parameters determine substitution validity:

• Circuit: SPST (required)
• Number of Positions: 8 (required)
• Mounting Type: Through Hole (required)
• Pitch: 0.100" (2.54mm) Full (required)
• Termination Style: PC Pin (required)

Engineering Selection Recommendations

Primary Recommendation: 3-5435802-8

The TE Connectivity ALCOSWITCH 3-5435802-8 is the direct equivalent replacement for the obsolete 3-435802-8. This part maintains identical mechanical and electrical specifications including piano actuator type, flush recessed actuator level, and washable construction. The 3-5435802-8 is active in production status and achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet. This part is supplied in tube packaging and represents the optimal substitution path for direct replacement applications.

Secondary Recommendation: 1-1825006-3

The TE Connectivity ALCOSWITCH 1-1825006-3 is the manufacturer-recommended alternative when actuator type substitution is acceptable. This part maintains the same manufacturer lineage, SPST circuit configuration, 8-position count, and through-hole mounting. The 1-1825006-3 features a slide standard actuator instead of piano actuator, with flush recessed actuator level. This part is ROHS3 compliant and REACH unaffected. Electrical specifications include 25mA current rating at 24VDC. The higher inventory availability (2980 pcs) supports production continuity.

Alternative Options: 76PRB08T, BD08, KAS1108ET

These parts provide functional substitution with alternative manufacturers and actuator types. Selection among these alternatives depends on specific application requirements regarding actuator interface, electrical ratings, and mechanical characteristics. All three parts are ROHS3 compliant and REACH unaffected, supporting modern regulatory compliance.

The 76PRB08T (Grayhill Inc.) maintains piano actuator type with raised actuator level and 150mA/30VDC electrical rating. The BD08 (C&K) features slide actuator with 100mA/5VDC rating and extended mechanical life (10,000 cycles). The KAS1108ET (E-Switch) provides slide actuator with 25mA/24VDC rating and tape seal feature.

Frequently Asked Questions (FAQ)

Q: Can the 3-5435802-8 be used as a direct replacement for the 3-435802-8?

A: Yes. The 3-5435802-8 maintains identical mechanical and electrical specifications including actuator type (piano), actuator level (flush, recessed), circuit configuration (SPST), position count (8), mounting type (through hole), and washable construction. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What is the difference between piano and slide actuators in DIP switch applications?

A: Actuator type determines the user interface for switch position selection. Piano actuators feature individual lever switches for each position, while slide actuators use a single sliding mechanism to select positions. Both types maintain identical electrical circuit configuration and mounting compatibility when pitch and position count are matched.

Q: Are the substitute parts with slide actuators (1-1825006-3, BD08, KAS1108ET) compatible with the original piano actuator design?

A: These parts are electrically and mechanically compatible at the board level due to matching circuit configuration (SPST), position count (8), pitch (0.100" / 2.54mm), and through-hole mounting. However, the user interface differs due to actuator type change. PCB layout and mechanical clearances remain compatible. Application-specific requirements regarding actuator accessibility and user interaction must be evaluated.

Q: What are the electrical rating differences among the substitute parts?

A: The original 3-435802-8 does not specify current or voltage ratings in the provided data. Substitute parts vary: 1-1825006-3 (25mA/24VDC), 76PRB08T (150mA/30VDC), BD08 (100mA/5VDC), and KAS1108ET (25mA/24VDC). Selection must align with application circuit requirements.

Q: Why is RoHS compliance important for this substitution?

A: The original 3-435802-8 is RoHS non-compliant and REACH affected. All active substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution in regulated markets.

Q: Does the washable characteristic affect substitution compatibility?

A: Washability indicates the part can withstand aqueous cleaning processes. The original part and most substitutes (3-5435802-8, 1-1825006-3, BD08, KAS1108ET) are washable. The 76PRB08T is not washable. Selection depends on manufacturing process requirements for post-assembly cleaning.

Q: What is the significance of the right-angle mounting option on the 76PRB08T?

A: The 76PRB08T offers through-hole right-angle mounting, which orients the switch body perpendicular to the PCB plane. This differs from standard through-hole mounting where the switch body is parallel to the PCB. Right-angle mounting affects PCB layout and mechanical clearance requirements and is not compatible with designs requiring standard through-hole orientation.

Q: How do mechanical and electrical life ratings compare among substitutes?

A: The original part does not specify life ratings. Substitutes vary: 1-1825006-3 (1,000 cycles), 76PRB08T (2,000 cycles), BD08 (10,000 cycles), and KAS1108ET (2,000 cycles). Higher cycle ratings indicate greater durability for applications requiring frequent position changes.
