Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZX40C30A01 is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Voltage rating (125V AC minimum)
• Actuator type (Round pin plunger)
• Mounting type (Through hole)
• Termination style (PC pin)
• Operating position (0.276" / 7.0mm)

Current Rating Consideration: The ZX40C30A01 is rated for 3A AC. Substitute parts must meet or exceed this current rating to function as direct replacements in the original circuit.

Identified Substitutes:

Full Equivalent: SS0750300F070P1A (E-Switch) matches all primary compatibility criteria and maintains the 3A current rating, making it a direct functional replacement.

Limited Equivalent: SS075Q100F070P1A (E-Switch) shares all primary compatibility criteria but is rated for 100mA AC current. This part is suitable only for applications where the circuit current requirement does not exceed 100mA, representing a downrated alternative.

Parameter Comparison

Engineering Selection Recommendations

SS0750300F070P1A Selection: This E-Switch part is the primary substitute for the ZX40C30A01. Both parts maintain identical current and voltage ratings (3A, 125V AC), circuit configuration (SPDT), and mechanical interface specifications (through-hole mounting, PC pin termination, 0.276" operating position). The SS0750300F070P1A carries active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment. The substitute exhibits superior electrical life (100,000 cycles versus 10,000 cycles), providing enhanced durability in high-cycle applications. Temperature range is narrower (-25°C to 75°C versus -40°C to 120°C); applications requiring operation below -25°C or above 75°C require thermal evaluation.

SS075Q100F070P1A Selection: This E-Switch part shares all mechanical and functional characteristics with the ZX40C30A01 but operates at reduced current capacity (100mA versus 3A). Selection of this part is limited to circuits where the maximum current requirement does not exceed 100mA. This part is not suitable as a general replacement for the ZX40C30A01 in applications requiring the full 3A rating. The part carries active product status with ROHS3 compliance and REACH unaffected designation.

Frequently Asked Questions (FAQ)

Q: Can SS0750300F070P1A directly replace ZX40C30A01 in all applications?

A: SS0750300F070P1A is a direct functional replacement for applications operating within the temperature range of -25°C to 75°C. Both parts share identical current rating (3A), voltage rating (125V AC), circuit configuration (SPDT), actuator type (round pin plunger), mounting type (through hole), and termination style (PC pin). Applications requiring operation outside this temperature range require thermal evaluation of the substitute part's suitability.

Q: Why is SS075Q100F070P1A listed as a substitute if it has lower current rating?

A: SS075Q100F070P1A is listed as a substitute based on mechanical and functional compatibility (SPDT circuit, on-momentary function, identical mechanical interface). However, the 100mA current rating represents a significant limitation. This part functions as a substitute only in applications where circuit current does not exceed 100mA. For applications requiring the full 3A rating, this part is not suitable.

Q: What are the key differences between the main part and substitutes?

A: Operating force differs (ZX40C30A01: 90gf; substitutes: 70gf). Release force differs (ZX40C30A01: 15gf; substitutes: 25gf). Operating temperature range is narrower for substitutes (-25°C to 75°C versus -40°C to 120°C). Electrical life is superior in substitutes (100,000 cycles versus 10,000 cycles). RoHS compliance level differs (RoHS Compliant versus ROHS3 Compliant).

Q: Are there packaging differences between these parts?

A: ZX40C30A01 is supplied in standard packaging. Both E-Switch substitutes are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the significance of product status differences?

A: ZX40C30A01 carries obsolete status, indicating discontinued manufacturing and limited future availability. Both substitute parts carry active status, ensuring ongoing production, supply chain availability, and manufacturer support. Active status is advantageous for long-term design continuity and procurement reliability.

Q: Do the substitutes meet current regulatory requirements?

A: Both E-Switch substitutes carry ROHS3 compliance and REACH unaffected designation, meeting current regulatory standards. The original ZX40C30A01 carries RoHS Compliant status. ROHS3 represents the current regulatory standard, making substitutes compliant with modern procurement requirements.
