Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5639MAB are identified based on the following critical parameters:

• Circuit Configuration: SPDT topology required for functional equivalence
• Switch Function: On-Off-On operation maintained
• Current Rating: Substitute parts must support minimum 5A AC/DC to ensure safe operation in applications designed for the 5639MAB
• Voltage Rating: AC voltage minimum 120V and DC voltage minimum 28V required
• Mounting Type: Panel mount configuration with compatible bushing thread (15/32-32)
• Panel Cutout Dimensions: Circular cutout diameter within acceptable mechanical tolerance
• Termination Style: Solder lug termination for circuit board integration
• Operating Temperature: Range must encompass or overlap primary operating conditions
• Compliance: ROHS3 compliance maintained across all substitutes

The substitute parts 100SP3T8B13M1QEH (E-Switch) and 7103TZQE (C&K) meet these criteria with minor parameter variations within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 100SP3T8B13M1QEH (E-Switch)

The E-Switch 100SP3T8B13M1QEH provides the closest functional match to the 5639MAB. Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory consistency. The E-Switch part maintains identical circuit topology, switch function, termination style, and bushing thread specification. AC voltage rating of 120V and DC rating of 28V are within acceptable operating parameters for applications designed for the 5639MAB. The 5A AC/DC current rating is suitable for circuits rated at or below this threshold. Panel cutout diameter difference (11.91mm vs 12.50mm) requires panel modification consideration.

Secondary Substitute: 7103TZQE (C&K)

The C&K 7103TZQE offers equivalent electrical and mechanical specifications to the E-Switch option. ROHS3 compliance is maintained; however, REACH status is listed as affected, requiring regulatory assessment for applications subject to REACH requirements. Electrical life rating of 40,000 cycles is lower than the primary part. All other functional parameters align with substitution criteria.

Considerations for Selection

Panel cutout diameter on both substitute parts (11.91mm) is smaller than the 5639MAB specification (12.50mm). Panel modification or adapter hardware may be required for mechanical installation. Operating temperature lower limit on substitute parts (-30°C) is higher than the 5639MAB (-40°C); applications requiring operation below -30°C require the original part. Electrical life cycle rating difference should be evaluated against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the 100SP3T8B13M1QEH directly replace the 5639MAB without panel modification?

A: The substitute part has a smaller panel cutout diameter (11.91mm vs 12.50mm). Direct installation in existing panel cutouts designed for the 5639MAB is not possible without enlarging the cutout or using mechanical adapters.

Q: What is the impact of the lower current rating on the substitute parts?

A: The substitute parts are rated for 5A AC/DC versus the 5639MAB at 6A AC and 4A DC. Substitutes are suitable for circuits designed for 5A or lower. Circuits requiring the full 6A AC rating of the original part cannot use these substitutes.

Q: Are there voltage rating differences that affect compatibility?

A: The 5639MAB is rated for 125V AC and 30V DC. Substitute parts are rated for 120V AC and 28V DC. These lower ratings are acceptable for applications operating at or below these voltage levels. Applications requiring the full 125V AC or 30V DC rating of the original part require the 5639MAB.

Q: What is the significance of the REACH status difference?

A: The E-Switch 100SP3T8B13M1QEH is REACH unaffected, matching the 5639MAB. The C&K 7103TZQE is REACH affected. Applications subject to REACH regulations should prioritize the E-Switch option or confirm regulatory compliance requirements with the C&K part.

Q: How do electrical life cycle ratings compare?

A: The 5639MAB is rated for 50,000 cycles; substitute parts are rated for 40,000 cycles. For applications with high switching frequency or long service life requirements, the original part provides extended operational life. Substitute parts are suitable for applications with moderate switching duty cycles.

Q: Are all parts ROHS3 compliant?

A: Yes. The 5639MAB, 100SP3T8B13M1QEH, and 7103TZQE are all ROHS3 compliant, ensuring consistency with environmental and regulatory requirements.
