Key Parameters

Substitute Part Grouping Explanation

Substitution of the 43-00099 is based on electrical and mechanical compatibility within the M12-4 circular connector family. The following parameters establish substitution validity:

Critical Matching Parameters:

• Connector type: Receptacle with male pins
• Number of positions: 4
• Shell size: M12-4
• Termination method: Screw
• Current rating: 4A
• Voltage rating: 250V
• Ingress protection: IP67
• Operating temperature range: -30°C to 85°C
• Contact material and finish: Copper zinc with gold plating
• Shell material: Polyamide (PA6), nylon 6, glass-filled

Variable Parameters Permitting Substitution:

• Cable opening diameter range
• Packaging configuration
• Product status (obsolete to active transition)

The substitute part 43-00100 maintains all critical electrical and mechanical specifications while offering active product status and expanded cable opening accommodation.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol CONEC 43-00100 serves as the direct substitute for the obsolete 43-00099. Both components maintain identical electrical specifications (4A current rating, 250V voltage rating) and mechanical configuration (M12-4 shell size, 4-position receptacle with male pins, screw termination).

The 43-00100 is classified as an active product, ensuring ongoing availability and manufacturer support. Both parts comply with ROHS3 and REACH requirements, with identical environmental certifications and MSL ratings.

The primary difference between the two parts is the cable opening diameter range. The 43-00099 accommodates cables from 4.00mm to 6.00mm, while the 43-00100 accommodates cables from 6.00mm to 8.00mm. Cable diameter compatibility must be verified during component selection to ensure proper fit and strain relief performance.

Frequently Asked Questions (FAQ)

Q: Can the 43-00100 directly replace the 43-00099 in existing designs?

A: The 43-00100 is electrically and mechanically compatible with the 43-00099 for all critical connector functions. However, the cable opening diameter range differs. The 43-00100 accommodates larger cable diameters (6.00mm to 8.00mm) compared to the 43-00099 (4.00mm to 6.00mm). Verify that your cable diameter falls within the 43-00100 specification before implementation.

Q: What is the significance of the product status change from obsolete to active?

A: The 43-00099 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 43-00100 is an active product with ongoing production and manufacturer support. Transitioning to the 43-00100 ensures long-term component availability and supply chain stability.

Q: Are there compliance differences between the two parts?

A: Both the 43-00099 and 43-00100 maintain identical compliance certifications: ROHS3 compliant, REACH unaffected, UL94 flammability rating, and EAR99 export classification. No compliance barriers exist for substitution.

Q: What determines whether a part can substitute for the 43-00099?

A: Substitution validity is established through matching of critical parameters: connector type (receptacle with male pins), position count (4), shell size (M12-4), termination method (screw), electrical ratings (4A/250V), ingress protection (IP67), operating temperature range (-30°C to 85°C), and contact materials (copper zinc with gold plating). Cable opening diameter is a variable parameter that permits substitution when the substitute accommodates the application cable size.

Q: What is the inventory status of these parts?

A: The 43-00099 has 1105 pieces in stock as new original inventory. The 43-00100 has 2298 pieces in stock as new original inventory in bulk packaging. The 43-00100 offers greater availability for procurement planning.
