Key Parameters

Substitute Part Grouping Explanation

Substitution for the Weidmüller 944170 RS 16ES relay coil is determined by the following critical parameters:

• Relay Coil Functional Type: Relay coil assembly compatible with RS 16ES interface
• RoHS Compliance: Substitute parts must maintain RoHS Compliant status for regulatory alignment
• REACH Compliance: REACH Unaffected status must be preserved in substitute selection
• Moisture Sensitivity Level: MSL 1 (Unlimited) rating ensures no moisture-related handling restrictions
• Base Product Compatibility: Parts derived from or compatible with the 94417 base product series

No direct substitute parts have been identified in the current database. Selection of alternative relay coil assemblies requires verification of mechanical mounting compatibility, electrical interface specifications, and compliance certifications against the original Weidmüller 944170 specification.

Engineering Selection Recommendations

For applications currently utilizing the Weidmüller 944170 RS 16ES relay coil, the following selection criteria apply:

• Compliance Maintenance: Any substitute component must maintain RoHS Compliant and REACH Unaffected status to ensure regulatory continuity
• Obsolescence Management: The obsolete product status requires proactive component qualification and validation before integration into production systems
• Stock Availability: With 735 pieces of original stock available, immediate replacement needs can be addressed through existing inventory while long-term alternatives are evaluated
• Interface Verification: Mechanical and electrical interface compatibility with the RS 16ES form factor must be confirmed before substitution

Frequently Asked Questions (FAQ)

Q: What makes the Weidmüller 944170 RS 16ES obsolete? A: The product status is classified as obsolete, indicating it is no longer manufactured by Weidmüller. Original stock remains available, but long-term sourcing requires identification of compatible alternatives.

Q: Are there any direct substitute parts available? A: No direct substitute parts are currently identified. Substitution requires evaluation of relay coil assemblies with compatible electrical and mechanical specifications.

Q: Does the RoHS Compliant status affect substitute selection? A: Yes. Any substitute component must maintain RoHS Compliant certification to ensure regulatory compliance and compatibility with modern procurement standards.

Q: What is the significance of MSL 1 (Unlimited)? A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions, simplifying storage and handling requirements for substitute components.

Q: How should I approach finding a suitable substitute? A: Identify relay coil assemblies with matching mechanical form factors, electrical interface specifications, and compliance certifications. Verify compatibility with the RS 16ES mounting and connection requirements before implementation.
