2M40FC Terminal Block Interface Module - Equivalent & Substitute Parts

Part Overview

The 2M40FC is a 40-position interface module terminal block manufactured by TE Connectivity AMP Connectors. This component features screw connection on the process side and rectangular male connector on the control side, designed for wire gauges 14-22 AWG. The 2M40FC is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M40FC is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• 40-position configuration
• Screw connection on process side
• Rectangular male connector on control side
• Latch-type cable retainer
• Wire gauge compatibility (minimum 14 AWG support required)

Electrical Compatibility Parameters:

• Voltage rating must equal or exceed 300V
• Current rating per contact must equal or exceed 10 A
• Operating temperature must support 120°C minimum

The substitute parts listed below maintain the 40-position, screw-to-rectangular male configuration with latch retainers. However, electrical ratings differ significantly from the original specification. Substitution is valid only when application requirements permit operation within the reduced electrical parameters of the substitute components.

Parameter Comparison

Engineering Selection Recommendations

2281076 (Phoenix Contact VARIOFACE FLKM Series)

This substitute maintains 40-position screw-to-rectangular male configuration with latch retention. Wire gauge range 12-24 AWG encompasses the original 14-22 AWG specification. The component is active and ROHS3 compliant with REACH unaffected status. Electrical ratings (60VDC, 1 A per contact) are significantly reduced from the original 300V, 10 A specification. This substitute is suitable for low-voltage, low-current applications only. Dimensional variance exists; length reduction of 0.271" and width increase of 0.281" require mechanical fit verification.

2315078 (Phoenix Contact VARIOFACE VIP Series)

This substitute provides 40-position screw-to-rectangular male configuration with identical latch retention. Wire gauge range 12-24 AWG is compatible with the original specification. The component is active and ROHS3 compliant with REACH unaffected status. Electrical ratings (60V, 1 A per contact) are substantially reduced from the original 300V, 10 A specification. This substitute is applicable to low-voltage, low-current applications only. Significant dimensional differences exist; length reduction of 1.653" and width reduction of 0.033" require mechanical fit assessment.

5726.2 (Altech Corporation)

This substitute maintains 40-position screw-to-rectangular male configuration with latch retention. Wire gauge range 12-22 AWG overlaps the original 14-22 AWG specification. The component is active and ROHS3 compliant with REACH unaffected status. Voltage rating of 250VAC approaches the original 300V specification; however, current rating of 3 A per contact is substantially reduced from the original 10 A specification. Operating temperature is not specified, preventing thermal compatibility assessment. Dimensional variance exists; length reduction of 0.210" and width increase of 0.680" require mechanical fit verification.

Frequently Asked Questions (FAQ)

Q: Can the 2281076 or 2315078 directly replace the 2M40FC in high-current applications?

A: No. Both Phoenix Contact substitutes are rated for 1 A per contact, compared to the original 2M40FC rating of 10 A per contact. These substitutes are suitable only for applications requiring 1 A or less per contact.

Q: What is the primary reason the 2M40FC is being discontinued?

A: The 2M40FC is classified as obsolete. Active substitute components from Phoenix Contact and Altech Corporation are available to fulfill 40-position terminal block requirements.

Q: Are the substitute parts physically interchangeable with the 2M40FC?

A: The substitute parts maintain identical functional connectivity (40-position screw-to-rectangular male with latches) but exhibit dimensional differences. The 2315078 shows the most significant length reduction (1.653"). Mechanical fit verification is required for each application before substitution.

Q: Which substitute part most closely matches the original voltage specification?

A: The 5726.2 (Altech) provides 250VAC rating, which most closely approaches the original 300V specification. However, current rating remains substantially reduced at 3 A per contact versus the original 10 A.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (2281076, 2315078, and 5726.2) are ROHS3 compliant. The original 2M40FC is RoHS non-compliant.

Q: What wire gauge compatibility exists between the original and substitute parts?

A: The original 2M40FC supports 14-22 AWG. All three substitutes support 12-24 AWG (2281076, 2315078) or 12-22 AWG (5726.2), providing wire gauge compatibility within the original specification range.

Q: Can the 5726.2 operate at the original 120°C operating temperature?

A: Operating temperature for the 5726.2 is not specified in available documentation. Thermal compatibility cannot be confirmed without additional manufacturer data.

Q: What is the inventory status of each substitute part?

A: 2281076 has 663 units in stock; 2315078 has 2200 units in stock; 5726.2 has 676 units in stock. All are available as new original components.
