Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101T2PV81LE are categorized based on the following critical parameters that determine functional compatibility:

Direct Substitutes maintain identical electrical and mechanical specifications:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Panel cutout dimensions: Circular 11.91mm Dia
• Bushing thread: 15/32-32
• Termination style: PC Pin
• Operating temperature: -30°C to 85°C

Similar Substitutes share the same circuit configuration, mounting interface, and termination style but operate within different electrical parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Panel cutout dimensions: Circular 11.91mm Dia
• Bushing thread: 15/32-32
• Termination style: PC Pin
• Operating temperature: -30°C to 85°C

Differences in current rating and voltage specifications require application-level verification to ensure the substitute part meets system requirements.

Parameter Comparison

Engineering Selection Recommendations

C&K 7101T2PV81RE is the primary substitute for the obsolete 7101T2PV81LE. Both components are from the same manufacturer and series with identical electrical ratings (5A at 120V AC / 28V DC), mechanical interface dimensions, and termination specifications. The 7101T2PV81RE maintains active product status and RoHS compliance, providing long-term availability and supply chain stability. This part requires no application-level modifications and represents a direct replacement.

Grayhill Inc. 34ASP18T7V3RT is a secondary substitute suitable only for applications where electrical requirements are lower than the original specification. This component operates at 0.4VA with 20V maximum ratings (both AC and DC), representing a significant reduction in power handling capability. The 34ASP18T7V3RT shares identical panel mounting dimensions and termination style but features reduced electrical life (40,000 cycles versus 100,000 cycles). Selection of this part requires confirmation that system voltage and current demands do not exceed 0.4VA at 20V.

Frequently Asked Questions (FAQ)

Q: Can the 7101T2PV81RE directly replace the obsolete 7101T2PV81LE without any modifications?

A: Yes. The 7101T2PV81RE is a direct substitute with identical electrical ratings (5A at 120V AC / 28V DC), panel cutout dimensions (11.91mm circular), bushing thread (15/32-32), and PC pin termination. No circuit or mechanical modifications are required.

Q: What are the key differences between the C&K 7101T2PV81RE and the Grayhill 34ASP18T7V3RT?

A: The primary differences are electrical ratings and manufacturer. The C&K part maintains the original 5A / 120V AC / 28V DC specification, while the Grayhill part is rated for 0.4VA at 20V maximum. The Grayhill part also has reduced electrical life (40,000 cycles versus 100,000 cycles). Both share identical panel mounting interfaces and SPDT configuration.

Q: Is the Grayhill 34ASP18T7V3RT suitable for all applications using the 7101T2PV81LE?

A: No. The Grayhill part is suitable only for applications where system voltage does not exceed 20V and current does not exceed 0.4VA. Applications requiring the full 5A capacity at 120V AC or 28V DC must use the C&K 7101T2PV81RE.

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

A: The C&K 7101T2PV81LE is RoHS3 compliant. The C&K 7101T2PV81RE is RoHS compliant with REACH affected status. The Grayhill 34ASP18T7V3RT is RoHS compliant with REACH unaffected status. All three parts carry EAR99 ECCN classification. Compliance requirements for your specific application should be verified against these certifications.

Q: What is the panel cutout requirement for installation?

A: All three parts require an 11.91mm diameter circular cutout with a 15/32-32 bushing thread. Panel mounting dimensions are identical across all substitute options.
