Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for toggle switches is determined by strict alignment of electrical and mechanical parameters. The following criteria establish whether a part qualifies as a functional equivalent:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount, Right Angle)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C ~ 85°C)

Electrical Compatibility Criteria:

• Current rating must meet or exceed application requirements
• Voltage ratings (AC and DC) must support the intended operating voltage
• Electrical life rating must satisfy cycle count expectations

The substitute part 34ASP11B1M6RT (Grayhill Inc.) shares identical mechanical mounting characteristics and circuit topology. However, electrical performance differs significantly: the substitute provides 0.4VA at 20V maximum, compared to the main part's 5A at 120V AC. This electrical limitation restricts the substitute to lower-power applications only.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (7101SPYA2QE): Recommended for applications requiring 5A switching capacity at 120V AC or 28V DC. Both the main part and substitute maintain ROHS3 compliance and active production status, ensuring regulatory alignment and supply availability. The 100,000-cycle electrical life rating supports extended-duty applications.

Substitute Part (34ASP11B1M6RT): Applicable only to low-power applications operating at 20V or below with current requirements not exceeding 0.4VA. The reduced electrical life rating (40,000 cycles) limits use to applications with moderate switching frequency. This substitute is suitable for signal-level switching or control circuits where power handling is minimal.

Selection between these parts must be based on actual application voltage and current requirements. The substitute cannot be used as a direct replacement in circuits designed for the 5A/120V specifications of the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 34ASP11B1M6RT substitute for the 7101SPYA2QE in all applications?

A: No. The substitute part has significantly lower electrical ratings (0.4VA at 20V maximum versus 5A at 120V AC). Substitution is only valid for applications operating at 20V or below with current draw not exceeding 0.4VA.

Q: What mechanical features are identical between these parts?

A: Both parts share identical panel mount configuration, right-angle orientation, 6.35mm circular panel cutout, 1/4-40 bushing thread, and PC pin termination. Physical installation is interchangeable; electrical compatibility depends on application requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 7101SPYA2QE and 34ASP11B1M6RT are ROHS3 compliant and maintain active production status.

Q: What is the difference in electrical life between these parts?

A: The 7101SPYA2QE is rated for 100,000 switching cycles, while the 34ASP11B1M6RT is rated for 40,000 cycles. Applications requiring frequent switching should use the primary part.

Q: Can I use the substitute in a 120V AC circuit?

A: No. The substitute part is rated for 20V AC maximum. Using it in a 120V AC circuit will result in component failure.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -30°C to 85°C, providing identical thermal performance characteristics.
