Amphenol CONEC 43-01191 Equivalent & Substitute Parts

Part Overview

The Amphenol CONEC 43-01191 is a 4-position circular connector receptacle with male pins, designed for panel mount through-hole applications with solder termination. This connector features IP67 ingress protection, gold-plated mating contacts, and operates across a temperature range of -30°C to 85°C. The part is currently active in production and maintains full RoHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate equivalent connector configurations with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol CONEC 43-01191 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Shell Size - Insert: M12-4
• Termination Method: Solder
• Mounting Type: Panel Mount, Through Hole
• Ingress Protection Rating: IP67
• Current Rating: 4A
• Voltage Rating: 250V
• Contact Finish - Mating: Gold
• Shielding: Shielded
• Insert Material: Polyamide (PA66), Nylon 6/6
• Flammability Rating: UL94 V-0

Acceptable Variations:

• Connector Type: Receptacle or Plug configurations
• Fastening Type: Threaded or Push-Twist
• Shell Material: Copper Zinc or Zinc Die Cast
• Operating Temperature Range: Minimum -25°C acceptable (main part: -30°C)
• Manufacturer: Different manufacturers permitted
• Features: Additional features (Ground, Board Guide) acceptable

The Phoenix Contact 1552955 meets all mandatory matching parameters and qualifies as a direct substitute with acceptable variations in fastening mechanism and operating temperature floor.

Engineering Selection Recommendations

Primary Part Selection: The Amphenol CONEC 43-01191 remains the specified component when available. This part maintains active production status with 1086 units in current inventory and full compliance with ROHS3 and REACH Unaffected designation.

Substitute Part Selection: The Phoenix Contact 1552955 qualifies as a direct substitute when the primary part is unavailable. Both parts maintain identical electrical ratings (4A at 250V), mechanical compatibility (M12-4 shell size, 4-position configuration), and environmental protection (IP67 rating). Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating.

Operational Considerations: The Phoenix Contact 1552955 operates across -25°C to 85°C, which represents a 5°C reduction in minimum operating temperature compared to the primary part (-30°C to 85°C). Applications requiring operation below -25°C must use the Amphenol CONEC 43-01191.

The Phoenix Contact 1552955 employs Push-Twist fastening versus the Threaded fastening of the primary part. Both fastening mechanisms are compatible with bulkhead front-side nut mounting configurations.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications, supporting equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1552955 directly replace the Amphenol CONEC 43-01191 in all applications?

A: The Phoenix Contact 1552955 is electrically and mechanically compatible for applications operating within -25°C to 85°C. Applications requiring operation below -25°C must use the Amphenol CONEC 43-01191. Both parts support identical current (4A) and voltage (250V) ratings with matching IP67 ingress protection and gold-plated contacts.

Q: What is the difference between the fastening mechanisms?

A: The Amphenol CONEC 43-01191 uses Threaded fastening, while the Phoenix Contact 1552955 uses Push-Twist fastening. Both mechanisms are compatible with bulkhead front-side nut mounting. The choice between fastening types depends on application assembly procedures and field maintenance requirements.

Q: Are both parts RoHS compliant?

A: Both the Amphenol CONEC 43-01191 and Phoenix Contact 1552955 are ROHS3 compliant. The Amphenol part carries REACH Unaffected status, while the Phoenix Contact part is REACH Affected. Applications subject to REACH restrictions should verify the Phoenix Contact part against specific regulatory requirements.

Q: Do both connectors provide equivalent shielding and environmental protection?

A: Both parts are shielded connectors with IP67 ingress protection rating (dust tight and waterproof). Both employ nickel-finished copper zinc or zinc die cast shells with gold-plated mating contacts. Environmental protection specifications are identical.

Q: What is the inventory status for each part?

A: The Amphenol CONEC 43-01191 has 1086 units in current inventory. The Phoenix Contact 1552955 has 1112 units in current inventory. Both parts are actively produced and available for immediate procurement.

Q: Are the insert materials identical?

A: Both parts use Polyamide (PA66), Nylon 6/6 insert material with UL94 V-0 flammability rating. Insert material specifications are identical.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
