Phoenix Contact 1843295 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1843295 is a 9-position terminal block header with male pins, designed for vertical through-hole mounting at 4.60mm pitch. This component is part of the COMBICON MCV series and is actively manufactured. Terminal block headers serve as connection interfaces in industrial control systems, power distribution, and signal routing applications. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and cost optimization when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1843295 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 9 positions at 0.138" (4.60mm) spacing
• Header Configuration: Male pins with 4-side shrouding
• Mounting Method: Vertical through-hole solder termination
• Electrical Ratings: Minimum 8 A current capacity and 300 V voltage rating (UL standard)
• Physical Compatibility: Contact tail length and insulation height must accommodate existing PCB layouts
• Compliance: RoHS3 compliance and UL94 V-0 flammability rating

The Molex 0395056009 (Eurostyle ESE 39505 series) meets all substitution criteria. Both components share identical position count, pitch, orientation, mounting type, and electrical performance specifications. Physical dimensions are equivalent within manufacturing tolerances. Both parts maintain active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1843295 and Molex 0395056009 are active products with full regulatory compliance. Selection between these components should be based on:

Phoenix Contact 1843295: Primary choice when PBT housing material is specified in design requirements or when COMBICON MCV series standardization is mandated.

Molex 0395056009: Suitable alternative when supply constraints affect Phoenix Contact availability. The Eurostyle ESE 39505 series provides equivalent electrical and mechanical performance. The specified operating temperature range of -40°C to 105°C provides explicit thermal performance documentation. Housing material differs (PA66 nylon versus PBT), which may affect mechanical properties in specific environmental conditions but does not impact electrical substitutability for standard applications.

Both parts maintain identical electrical ratings, position configuration, pitch, and mounting characteristics. PCB layout modifications are not required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395056009 be used as a direct replacement for the Phoenix Contact 1843295 on existing PCBs?

A: Yes. Both components share identical pitch (4.60mm), position count (9), contact tail length (0.138"), and mounting type (vertical through-hole solder). PCB footprints are compatible. Insulation height differs by 0.002" (0.06mm), which is within standard manufacturing tolerance and does not affect board-level compatibility.

Q: What is the primary difference between these two parts?

A: Housing material differs. The Phoenix Contact uses polybutylene terephthalate (PBT), while the Molex uses polyamide (PA66) nylon. Both materials meet UL94 V-0 flammability requirements. Electrical performance, current capacity, voltage rating, and mechanical dimensions are equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Phoenix Contact 1843295 and Molex 0395056009 are ROHS3 compliant and suitable for applications requiring restricted substance compliance.

Q: Does the Molex part have a specified operating temperature range?

A: Yes. The Molex 0395056009 is rated for -40°C to 105°C operation. The Phoenix Contact 1843295 does not specify an operating temperature range in available documentation. For applications requiring explicit thermal performance data, the Molex specification provides this information.

Q: Are there any compliance or certification differences?

A: Both parts carry UL94 V-0 flammability ratings and are ROHS3 compliant. Both maintain active product status. No compliance gaps exist between these components for standard industrial applications.
