EP11FPD1SAKE Equivalent & Substitute Parts

Part Overview

The EP11FPD1SAKE is a pushbutton switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a current rating of 0.4VA at 20V. This surface mount, right-angle component features a round plunger actuator with flush design and gull wing termination, sealed with epoxy-protected terminals for IP57 ingress protection.

The EP11FPD1SAKE is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and replacement applications where this switch is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EP11FPD1SAKE is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Electrical Ratings: Current (0.4VA AC/DC) and voltage (20V AC/DC) must match or exceed specifications
• Mechanical Interface: Surface mount, right-angle orientation with gull wing termination
• Actuator Characteristics: Round plunger with flush design
• Environmental Protection: IP57 ingress protection rating
• Operating Conditions: Temperature range -30°C to 85°C and 60,000 cycle electrical life
• Sealing: Epoxy sealed terminals

The EP11FPD1SAPE qualifies as a direct substitute based on identical electrical, mechanical, and environmental specifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The EP11FPD1SAPE is the direct functional equivalent to the obsolete EP11FPD1SAKE. Both components share identical electrical specifications, mechanical interfaces, and environmental ratings. Selection between these parts should be based on the following factors:

Product Availability: The EP11FPD1SAPE carries Active product status with 1,360 units in stock, whereas the EP11FPD1SAKE is obsolete with limited remaining inventory (859 units).

Regulatory Compliance: The EP11FPD1SAPE meets ROHS3 compliance requirements, while the EP11FPD1SAKE is RoHS non-compliant. For applications subject to RoHS directives, the EP11FPD1SAPE is the required selection.

Packaging Format: The EP11FPD1SAPE is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The EP11FPD1SAKE packaging format is not specified.

For new designs or component replacement in RoHS-regulated applications, the EP11FPD1SAPE is the appropriate selection. For legacy systems where RoHS compliance is not mandated, either part meets functional requirements.

Frequently Asked Questions (FAQ)

Q: Are EP11FPD1SAKE and EP11FPD1SAPE electrically interchangeable?

A: Yes. Both components are rated for 0.4VA at 20V (AC/DC), feature SPST-NO circuit configuration, and support identical operating conditions (-30°C to 85°C, 60,000 electrical cycles).

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (unspecified vs. Tape & Reel). Electrical and mechanical specifications are identical.

Q: Can I use EP11FPD1SAPE as a direct replacement for EP11FPD1SAKE in existing assemblies?

A: Yes. The EP11FPD1SAPE is mechanically and electrically equivalent. Surface mount orientation, gull wing termination, and actuator design are identical, enabling direct PCB substitution.

Q: Does the Tape & Reel packaging of EP11FPD1SAPE affect compatibility?

A: No. Tape & Reel packaging is a supply format for automated assembly. Once soldered to the PCB, the component function and performance are identical to other packaging formats.

Q: Why is RoHS compliance important for this substitution?

A: RoHS (Restriction of Hazardous Substances) compliance is a regulatory requirement in many markets. The EP11FPD1SAPE's ROHS3 compliance ensures the component meets environmental and safety standards required for distribution in regulated regions.

Q: Are there any thermal or mechanical performance differences?

A: No. Both components operate across the same temperature range (-30°C to 85°C) and support identical mechanical life specifications and ingress protection ratings (IP57).
