Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 435640-1 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPST)
• Current rating (60mA)
• Voltage rating (5VDC)
• Actuator type (Rocker)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Contact material and finish (Copper Alloy, Gold)
• Operating temperature range (-55°C to 105°C)
• Mechanical and electrical life (2,000 Cycles)

Secondary Consideration:

• Number of positions (7 for direct equivalence)
• Physical dimensions and pitch (0.100" / 2.54mm)

Parts are classified as Direct Manufacturer Equivalents when all primary criteria are met with identical position count. Parts with differing position counts are classified as Similar alternatives and require application-specific validation.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: 5435640-1

The 5435640-1 is the primary substitute for the obsolete 435640-1. Both components share identical electrical specifications, mechanical configuration, and physical dimensions. The 5435640-1 maintains Last Time Buy status with significantly higher inventory availability (6,966 pieces versus 793 pieces). This part carries ROHS3 compliance certification and MSL Level 1 rating, providing enhanced environmental and regulatory alignment for new designs. The transition from bulk to tube packaging offers improved component protection during storage and handling.

Similar Alternative: 4-5435640-0

The 4-5435640-0 functions as a similar alternative when application requirements accommodate a 9-position configuration instead of 7 positions. This part shares all primary electrical and mechanical parameters with the main component. The 4-5435640-0 includes sealed construction and washable features not present in the 435640-1, providing enhanced environmental protection. Physical length increases from 0.780" to 0.980" due to the additional positions. This part also carries ROHS3 compliance and MSL Level 1 rating. Selection of this alternative requires confirmation that the increased position count and physical dimensions are compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can the 5435640-1 be used as a direct replacement for the 435640-1?

A: Yes. The 5435640-1 is a direct equivalent. Both components share identical electrical ratings (60mA, 5VDC), circuit configuration (SPST), position count (7), actuator type (rocker), mounting method (through hole), and operating temperature range (-55°C to 105°C). The primary differences are product status (Last Time Buy versus Obsolete), packaging format (tube versus bulk), and regulatory compliance (ROHS3 certification).

Q: What are the key differences between the 5435640-1 and 4-5435640-0?

A: The primary difference is position count: the 5435640-1 has 7 positions while the 4-5435640-0 has 9 positions. This results in a length increase from 0.780" to 0.980". The 4-5435640-0 includes sealed construction and washable features. All other electrical and mechanical parameters remain identical. Selection depends on whether the application can accommodate the additional positions and increased physical length.

Q: Are there any compliance or regulatory differences between these parts?

A: The 435640-1 lists RoHS status as Not Applicable. Both substitute parts (5435640-1 and 4-5435640-0) carry ROHS3 Compliant certification. Both substitutes have MSL Level 1 (Unlimited) ratings. All three parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications.

Q: What is the impact of packaging differences?

A: The 435640-1 is supplied in bulk packaging, while both 5435640-1 and 4-5435640-0 are supplied in tube packaging. Tube packaging provides improved component protection, organization, and handling efficiency. This difference does not affect electrical or mechanical performance.

Q: Can the 4-5435640-0 be used in applications designed for the 435640-1?

A: The 4-5435640-0 can be used only if the application design accommodates a 9-position switch instead of 7 positions and the increased physical length (0.980" versus 0.780"). All electrical parameters and operating characteristics are compatible. The sealed and washable features of the 4-5435640-0 provide additional environmental protection not present in the original design.

Q: What inventory considerations should guide part selection?

A: The 435640-1 has 793 pieces in stock with Obsolete status. The 5435640-1 has 6,966 pieces available with Last Time Buy status, providing significantly greater procurement flexibility. The 4-5435640-0 has 4,374 pieces available, also with Last Time Buy status. For new designs or long-term production, the 5435640-1 is the recommended choice due to higher availability and Last Time Buy designation.
