Substitute Part Grouping Explanation

Substitution eligibility for the PI84-24DC-M91G is determined by strict equivalence across the following critical parameters:

• Manufacturer: Altech Corporation
• Series: PI84
• Coil Voltage: 24VDC
• Contact Form: DPDT (2 Form C)
• Contact Rating: 8 A
• Switching Voltage: 250VAC, 24VDC - Max
• Coil Current: 16.7 mA
• Coil Resistance: 1.44 kOhms
• Mounting Type: DIN Rail
• Termination Style: Screw Terminal
• Coil Type: Non Latching

The PI84-24DC-M41G meets all substitution criteria as a parametric equivalent within the PI84 series, maintaining identical electrical specifications and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both PI84-24DC-M91G and PI84-24DC-M41G are Active products with ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on inventory availability and procurement lead times, as all electrical and mechanical parameters are identical. The PI84-24DC-M91G currently maintains higher stock levels at 1083 units. Both parts are suitable for direct substitution in applications requiring 24VDC DPDT relay functionality with 8A contact rating on DIN rail installations.

Frequently Asked Questions (FAQ)

Q: Can PI84-24DC-M41G replace PI84-24DC-M91G in existing installations?

A: Yes. Both parts are parametric equivalents with identical coil voltage (24VDC), contact form (DPDT), contact rating (8A), switching voltage (250VAC, 24VDC - Max), coil current (16.7 mA), and mounting configuration (DIN Rail with screw terminals). Direct substitution is supported.

Q: What determines substitution eligibility for PI84 series relays?

A: Substitution requires equivalence across coil voltage, contact form, contact rating, switching voltage, coil current, coil resistance, mounting type, and termination style. Variations in these parameters disqualify parts from substitution.

Q: Are there compliance differences between these substitute parts?

A: No. Both PI84-24DC-M91G and PI84-24DC-M41G maintain identical RoHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification.

Q: How do I verify compatibility before ordering a substitute?

A: Cross-reference the coil voltage requirement (24VDC), contact configuration need (DPDT), current rating (8A), and mounting type (DIN Rail) against the parameter comparison table. Matching values across all critical parameters confirm compatibility.

Q: What is the difference between these two part numbers if all parameters are identical?

A: The suffix designations (M91G vs. M41G) represent different packaging or configuration variants within the PI84-24DC base product line. Electrical and mechanical specifications remain equivalent.
