Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-1617100-2 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Coil voltage: 18VDC (primary control signal requirement)
• Coil current: 20 mA (power supply design constraint)
• Contact form: DPDT (2 Form C) (switching topology requirement)
• Contact rating: 1 A (load handling capacity)
• Switching voltage: 28VDC nominal (signal level compatibility)
• Coil resistance: 880 Ohms (circuit impedance matching)

Mechanical Compatibility Criteria:

• Mounting type: Through Hole (PCB integration method)
• Termination style: PC Pin (connection interface)

The MW6-18P satisfies all mandatory electrical parameters and maintains identical mechanical mounting and termination specifications, establishing it as a direct functional equivalent despite differences in operating temperature range and switching timing characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MW6-18P represents the active equivalent for the obsolete 1-1617100-2 based on the following factors:

Electrical Equivalence: Both parts maintain identical coil voltage (18VDC), coil current (20 mA), contact form (DPDT), contact rating (1 A), switching voltage (28VDC nominal), coil power (368mW), and coil resistance (880 Ohms). These parameters establish functional interchangeability for circuit-level integration.

Mechanical Compatibility: Both parts utilize through-hole mounting with PC pin termination, ensuring direct PCB footprint compatibility without redesign requirements.

Regulatory Compliance: The MW6-18P maintains REACH Unaffected status and EAR99 ECCN classification, consistent with the original part. The substitute achieves RoHS3 compliance, providing enhanced environmental regulatory alignment for new designs.

Product Status: The transition from obsolete (1-1617100-2) to active (MW6-18P) status ensures long-term supply chain availability and manufacturing continuity.

Operating Envelope Considerations: The MW6-18P operates within a narrower temperature range (-55°C to 85°C versus -65°C to 125°C) and exhibits longer switching times (4 ms operate, 3 ms release versus 2 ms operate, 1.5 ms release). Applications requiring the full temperature range or faster switching response require evaluation against system specifications.

Frequently Asked Questions (FAQ)

Q: Can the MW6-18P directly replace the 1-1617100-2 in existing designs?

A: The MW6-18P provides electrical and mechanical equivalence for the core relay function. Direct substitution is supported for applications operating within the MW6-18P temperature range (-55°C to 85°C) and tolerating the longer switching times (4 ms operate, 3 ms release). Applications requiring operation below -55°C or above 85°C, or demanding faster switching response, require design evaluation.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is established through matching coil voltage (18VDC), coil current (20 mA), contact form (DPDT), contact rating (1 A), switching voltage (28VDC nominal), coil resistance (880 Ohms), and coil power (368mW). These parameters ensure circuit-level functional equivalence.

Q: Are there mechanical differences between these parts?

A: Both parts utilize identical through-hole mounting and PC pin termination, eliminating mechanical redesign requirements for PCB integration.

Q: What compliance certifications apply to the substitute part?

A: The MW6-18P maintains REACH Unaffected status and EAR99 ECCN classification. Additionally, the MW6-18P achieves RoHS3 compliance, providing enhanced environmental regulatory alignment compared to the original part.

Q: How do the switching characteristics differ?

A: The 1-1617100-2 operates with 2 ms operate time and 1.5 ms release time. The MW6-18P exhibits 4 ms operate time and 3 ms release time. Applications with timing-critical switching requirements require evaluation against system specifications.

Q: What is the must-operate voltage difference between these parts?

A: The 1-1617100-2 must operate at 10.5 VDC minimum, while the MW6-18P requires 13 VDC minimum. This difference affects coil drive circuit design and should be evaluated for applications with marginal supply voltage conditions.
