PI85-24DC-M91G General Purpose Relay DPDT 24VDC

Part Overview

The PI85-24DC-M91G is a general purpose relay manufactured by Altech Corporation, featuring a DPDT (2 Form C) contact configuration with a 24VDC coil. This DIN rail-mounted relay is designed for switching applications up to 16A at 250VAC or 24VDC. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The PI85-24DC-M91G has one parametric equivalent substitute: PI85-24DC-M41G. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Coil voltage: 24VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 16 A
• Switching voltage: 250VAC, 24VDC - Max
• Coil current: 16.7 mA
• Coil type: Non Latching
• Mounting type: DIN Rail
• Termination style: Screw Terminal
• Coil resistance: 1.44 kOhms
• Must operate voltage: 16.8 VDC

Both parts belong to the PI85 series and share identical electrical and mechanical specifications, making them directly interchangeable in applications requiring these exact parameters.

The PI85-24DC-M91G currently has higher inventory availability at 1019 pieces, while the PI85-24DC-M41G has 892 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can PI85-24DC-M41G be used as a direct replacement for PI85-24DC-M91G?

A: Yes. Both parts are parametric equivalents with identical coil voltage (24VDC), contact form (DPDT), current rating (16A), switching voltage (250VAC/24VDC), and all other electrical and mechanical specifications. They are directly interchangeable.

Q: What determines if a relay can substitute for the PI85-24DC-M91G?

A: Substitution requires exact matching of coil voltage, contact form, contact rating, switching voltage, coil current, coil type, mounting type, termination style, coil resistance, and must operate voltage. Any deviation in these parameters disqualifies a part from substitution.

Q: Are there any compliance differences between these parts?

A: No. Both PI85-24DC-M91G and PI85-24DC-M41G carry identical RoHS3 compliance and REACH unaffected status.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The difference in part numbers (M91G vs M41G) reflects different manufacturing batches or packaging configurations, but they maintain the same functional specifications and are fully interchangeable.

Q: Which part should I select based on availability?

A: Selection should be based on current inventory levels and delivery requirements. The PI85-24DC-M91G has higher stock availability (1019 pcs) compared to PI85-24DC-M41G (892 pcs).
