Phoenix Contact 1933309 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1933309 is a 14-position terminal block header with male pins, unshrouded design, and 0.197" (5.00mm) vertical pitch. This component is used for power distribution, signal routing, and interconnection applications requiring solder termination and through-hole mounting. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and connector specifications align with the original design requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1933309 is determined by strict alignment of the following parameters:

Position Count & Pitch: 14 positions at 0.197" (5.00mm) spacing
Connector Type: Header with male pins, unshrouded configuration
Orientation & Mounting: Vertical orientation with through-hole solder termination
Physical Dimensions: Contact tail length of 0.138" (4.60mm) and insulation height of 0.079" (2.00mm)
Material & Safety: UL94 V-0 flammability rating and RoHS compliance

The TE Connectivity AMP Connectors part 1-1546214-4 meets all critical substitution criteria. Both components share identical position count, pitch, connector type, orientation, mounting method, and physical dimensions. Both maintain UL94 V-0 material flammability ratings and RoHS compliance status, ensuring functional and regulatory equivalence.

Engineering Selection Recommendations

Both the Phoenix Contact 1933309 and TE Connectivity 1-1546214-4 are active production components with equivalent electrical and mechanical specifications. Selection between these parts is based on availability, supply chain considerations, and design documentation requirements.

The Phoenix Contact 1933309 is specified in the original design with 727 units in current inventory. The TE Connectivity 1-1546214-4 provides functional equivalence with 918 units available, offering an alternative source for procurement continuity.

Both components maintain RoHS compliance (Phoenix Contact: RoHS Compliant; TE Connectivity: ROHS3 Compliant) and UL94 V-0 material flammability ratings. Both are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

The housing material differs slightly (Phoenix Contact uses PA/Nylon; TE Connectivity uses PA66/Nylon 6/6), but both materials meet the same flammability and mechanical performance requirements for this application class.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1546214-4 be used as a direct replacement for the Phoenix Contact 1933309?

A: Yes. Both components share identical position count (14), pitch (5.00mm), connector type (male pins, unshrouded), orientation (vertical), mounting method (through-hole solder), and physical dimensions (contact tail 4.60mm, insulation height 2.00mm). Both maintain UL94 V-0 flammability ratings and RoHS compliance.

Q: Are there differences in electrical ratings between these parts?

A: The Phoenix Contact 1933309 specifies IEC ratings of 12A at 400V and UL ratings of 16A at 300V. The TE Connectivity 1-1546214-4 does not provide IEC current rating in the available data. For applications requiring specific electrical performance verification, consult manufacturer datasheets.

Q: What is the difference between the housing materials?

A: Phoenix Contact uses polyamide (PA) nylon, while TE Connectivity uses polyamide (PA66) nylon 6/6. Both materials meet UL94 V-0 flammability requirements and are suitable for the same application environments.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly.

Q: Are both parts RoHS compliant?

A: Yes. Phoenix Contact 1933309 is RoHS Compliant. TE Connectivity 1-1546214-4 is ROHS3 Compliant. Both meet RoHS requirements for lead-free and restricted substance compliance.
