Key Parameters

Substitute Part Grouping Explanation

No direct substitute parts are available in the provided database. Substitution for the EA20501 must be evaluated based on the following critical parameters that define functional equivalence:

• Contact Configuration: SPDT (Single Pole Double Throw)
• Contact Current Rating: 6A minimum
• Coil Voltage Compatibility: 8/5V TTL logic levels
• Compliance Requirements: RoHS Compliant status
• Environmental Classification: MSL 1 (Unlimited moisture sensitivity)

Any replacement component must match or exceed these specifications to ensure functional compatibility in the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The EA20501 is obsolete and no longer manufactured. When selecting a replacement component, prioritize the following criteria:

• Ensure the substitute relay maintains SPDT contact configuration with minimum 6A current rating
• Verify coil voltage compatibility with 8/5V TTL logic signal levels
• Confirm RoHS compliance status to meet current regulatory requirements
• Maintain MSL 1 classification for unlimited moisture sensitivity tolerance
• Consult component datasheets to validate electrical and mechanical compatibility with the original circuit design

Frequently Asked Questions (FAQ)

Q: What makes a relay suitable as a substitute for the EA20501?

A: A substitute relay must provide SPDT contact configuration, support 6A contact current rating, accept 8/5V TTL coil voltage, and maintain RoHS compliance. The relay must be compatible with the original PCB footprint and mounting requirements.

Q: Why is the EA20501 no longer available?

A: The EA20501 is classified as obsolete and has been discontinued by Weidmüller. Obsolete components are no longer manufactured or stocked by distributors.

Q: Are there known direct replacements for this part?

A: No direct substitute parts are documented in the current reference database. Component selection must be based on matching the specified electrical parameters and compliance requirements.

Q: What should be verified before implementing a substitute relay?

A: Verify contact configuration, current rating, coil voltage compatibility, package dimensions, pin configuration, and compliance certifications against the original EA20501 specifications and your application requirements.

Q: Does the substitute need to be RoHS compliant?

A: Yes. The original EA20501 is RoHS compliant. Any substitute should maintain RoHS compliance to meet current regulatory and procurement standards.
