Key Parameters

Substitute Part Grouping Explanation

No direct substitute parts are currently available in the provided database. Substitution for the EA25277 position terminal block must be evaluated based on the following critical parameters:

• Product category classification (Terminal Blocks)
• Series compatibility (RS ELCO 20-36 RH)
• Functional type (Position Terminal Block)
• RoHS compliance status
• Moisture sensitivity level (MSL 1)
• REACH regulatory compliance

Equivalent components must match these core specifications to ensure functional and regulatory compatibility in the original application.

Parameter Comparison

No substitute parts are available for comparison at this time.

Engineering Selection Recommendations

When the EA25277 is no longer available, component selection must prioritize:

• Verification of RoHS compliance status to maintain regulatory alignment with the original specification
• Confirmation of REACH compliance to ensure no regulatory conflicts
• Matching of terminal block series and position specifications to maintain mechanical and electrical compatibility
• Moisture sensitivity level compatibility (MSL 1 or equivalent) for storage and handling requirements

The obsolete status of this component necessitates early identification of alternative sources or redesign considerations for long-term system reliability.

Frequently Asked Questions (FAQ)

Q: Why is the EA25277 marked as obsolete? A: The EA25277 has been discontinued by Weidmüller and is no longer manufactured. Existing inventory may be available through authorized distributors, but long-term availability cannot be guaranteed.

Q: What parameters must a substitute terminal block match? A: A substitute must match the product category (Terminal Blocks), series designation (RS ELCO 20-36 RH), functional type (Position Terminal Block), and maintain equivalent RoHS and REACH compliance status.

Q: Are there known compatible alternatives from other manufacturers? A: No direct equivalents are documented in the current database. Substitution evaluation requires detailed comparison of mechanical dimensions, electrical ratings, and mounting specifications against candidate components.

Q: How should MSL 1 rating be interpreted for storage? A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. Substitute components should maintain this or equivalent moisture sensitivity classification.

Q: What is the significance of REACH Unaffected status? A: This designation confirms that the component is not subject to REACH substance restrictions, ensuring regulatory compliance in EU and related markets.
