Key Parameters

Substitute Part Grouping Explanation

Substitution of the 435626-5 is based on electrical and mechanical compatibility within the following parameters:

Electrical Compatibility Criteria:

• SPST circuit configuration maintained
• 25mA current rating requirement
• 24VDC voltage rating requirement
• 8-position switch configuration

Mechanical Compatibility Criteria:

• Through-hole mounting type
• 0.100" (2.54mm) pitch spacing
• PC pin termination style
• Flush/recessed actuator level
• Copper alloy contacts with gold finish

Substitution Variance Allowances:

• Actuator type may differ (rocker to slide or equivalent)
• Height above board may vary within PCB design constraints
• Operating temperature range may be narrower in active alternatives
• Mechanical and electrical life cycles may differ
• Body material composition may differ
• RoHS compliance status may improve in active alternatives

The substitute part 1-1825006-3 meets all electrical requirements and maintains mechanical compatibility through standard through-hole mounting and identical pitch specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity ALCOSWITCH 1-1825006-3

The 1-1825006-3 is the manufacturer-recommended substitute for the obsolete 435626-5. This part maintains full electrical compatibility with identical SPST circuit configuration, 25mA current rating, and 24VDC voltage specification across all 8 positions. Mechanical compatibility is preserved through standard through-hole mounting with 0.100" pitch spacing and PC pin termination.

Compliance Advantages: The 1-1825006-3 achieves ROHS3 compliance, addressing regulatory requirements that the non-compliant 435626-5 cannot satisfy. This is a critical consideration for new product designs and procurement in regulated markets.

Design Considerations: The substitute part features a reduced height above board (0.114" versus 0.290"), which may provide PCB layout advantages in space-constrained applications. The actuator type transitions from rocker to slide configuration; both maintain flush/recessed actuator levels and are functionally equivalent for DIP switch operation.

Operating Environment: The substitute part operates within -30°C to 85°C, which is narrower than the original -55°C to 105°C range. Applications requiring extended temperature operation below -30°C or above 85°C require evaluation against the specified operating environment.

Life Cycle Specifications: The substitute part specifies 1,000 mechanical and electrical cycles compared to 7,000 cycles for the original. Applications with high cycle count requirements must assess this parameter against actual operational demands.

Active Product Status: The 1-1825006-3 maintains active product status with current manufacturing and availability, ensuring long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825006-3 directly replace the 435626-5 in existing PCB designs?

A: Yes, for applications within the specified operating parameters. Both parts share identical electrical ratings (SPST, 25mA, 24VDC, 8-position), through-hole mounting, 0.100" pitch, and PC pin termination. The reduced height above board (0.114" versus 0.290") is mechanically compatible with standard through-hole PCB layouts. The actuator type change from rocker to slide does not affect electrical function.

Q: What are the temperature operating limitations of the substitute part?

A: The 1-1825006-3 operates from -30°C to 85°C, compared to the original -55°C to 105°C range. Applications requiring operation below -30°C or above 85°C must remain on the original 435626-5 or identify alternative parts with extended temperature specifications.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The 1-1825006-3 is ROHS3 compliant, whereas the 435626-5 is non-compliant. For applications subject to RoHS regulations, the substitute part satisfies current compliance requirements.

Q: Are there differences in mechanical durability between these parts?

A: Yes. The 435626-5 specifies 7,000 mechanical and electrical cycles, while the 1-1825006-3 specifies 1,000 cycles. Applications with high actuation frequency must evaluate whether 1,000 cycles meets operational requirements.

Q: What is the significance of the actuator type change from rocker to slide?

A: Both rocker and slide actuators are standard DIP switch configurations that perform identical electrical switching functions. The change affects only the physical actuation method and user interface; electrical performance and circuit behavior remain equivalent.

Q: Is the substitute part available in the same packaging format?

A: The 1-1825006-3 is supplied in tube packaging, whereas the original part number does not specify packaging format in the provided data. Confirm packaging requirements with procurement specifications.

Q: What is the washable feature difference between these parts?

A: The 435626-5 is not washable, while the 1-1825006-3 includes a tape seal and is washable. This allows the substitute part to withstand aqueous cleaning processes during PCB assembly, providing manufacturing process flexibility.
