EM359305VC Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The EM359305VC is a 5-position terminal block header manufactured by Eaton Electronics Division, part of the Euro-Mag EM3593 series. This component is a male pin, shrouded terminal block header with 0.150" (3.81mm) pitch spacing, designed for vertical through-hole mounting with solder termination. The part is currently active in production with 1099 units in stock. Terminal block headers of this type are essential interconnection components in industrial control systems, power distribution modules, and modular electronic equipment where reliable, field-replaceable connections are required. Equivalent substitute parts may be necessary due to supply chain constraints, design standardization across manufacturing facilities, or end-of-life considerations for legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EM359305VC with equivalent parts is determined by strict alignment of the following critical parameters:

Position Count and Pitch: The substitute part must have exactly 5 positions with 0.150" (3.81mm) pitch spacing. This ensures mechanical and electrical compatibility with mating connectors and PCB layouts designed for the original component.

Header Configuration: The substitute must be a male pin header with 4-side shrouding in vertical orientation. This configuration provides the same mechanical interface and polarization protection as the original part.

Mounting and Termination: Through-hole mounting with solder termination is required to maintain compatibility with existing PCB designs and assembly processes.

Electrical Ratings: The substitute must meet or exceed the UL voltage and current specifications. The original part is rated for 160 V and 6 A under UL standards.

Material and Flammability: UL94 V-0 flammability rating is a mandatory requirement for safety-critical applications. Housing material may vary (thermoplastic or polybutylene terephthalate) provided the flammability rating is maintained.

Physical Dimensions: Insulation height of 0.362" (9.20mm) must be preserved to ensure proper clearance and fit within the mechanical envelope of the application.

The Phoenix Contact 1803455 meets all these critical substitution criteria and is therefore classified as a direct equivalent.

Engineering Selection Recommendations

Primary Selection - EM359305VC (Eaton): Use this part for applications where the original design specification and component qualification are locked. This part is active in production with adequate inventory (1099 units). However, note that this component is RoHS non-compliant, which may restrict its use in new designs subject to RoHS3 regulations.

Equivalent Substitute - 1803455 (Phoenix Contact): This part is a direct functional equivalent and is recommended as a substitute when:

• Supply of the EM359305VC becomes constrained or unavailable
• Design standardization across multiple manufacturing sites requires consolidation to a single supplier
• New designs require RoHS3 compliance; the 1803455 is ROHS3 compliant
• Higher electrical ratings are acceptable; the 1803455 provides 300 V UL and 8 A UL ratings, exceeding the original 160 V and 6 A specifications
• REACH compliance documentation is required; the 1803455 is REACH Unaffected

All critical mechanical and electrical parameters align between these two parts. The Phoenix Contact 1803455 is available in higher quantity (17930 units in stock), providing supply security for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1803455 be used as a direct replacement for the EM359305VC in existing designs?

A: Yes. Both parts share identical mechanical interfaces (5 positions, 0.150" pitch, vertical orientation, through-hole mounting) and identical flammability ratings (UL94 V-0). The Phoenix Contact part exceeds the electrical ratings of the original, making it electrically compatible with all applications designed for the EM359305VC.

Q: What is the difference in housing material between these two parts?

A: The EM359305VC uses thermoplastic housing, while the 1803455 uses polybutylene terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating. PBT offers superior chemical resistance and dimensional stability at elevated temperatures. This material difference does not affect mechanical or electrical compatibility.

Q: Are there any compliance differences between these parts?

A: Yes. The EM359305VC is RoHS non-compliant, while the 1803455 is ROHS3 compliant. The 1803455 also provides REACH Unaffected status. For new designs or applications subject to RoHS3 regulations, the Phoenix Contact part is the appropriate selection.

Q: Do these parts have the same electrical ratings?

A: No. The EM359305VC is rated for 160 V and 6 A under UL standards. The 1803455 is rated for 300 V and 8 A under UL standards, plus 250 V and 8 A under IEC standards. The substitute part exceeds the original specifications, ensuring compatibility with all applications designed for the original part.

Q: What is the contact mating finish on both parts?

A: Both parts use tin contact mating finish, ensuring identical electrical contact characteristics and solderability.

Q: Are the insulation heights identical?

A: Yes. Both parts have an insulation height of 0.362" (9.20mm), ensuring identical mechanical fit and clearance within the application's physical envelope.

Q: Which part should be selected for new designs?

A: For new designs, the Phoenix Contact 1803455 is recommended due to its ROHS3 compliance, higher electrical ratings, and superior material properties (PBT housing). The part is also available in significantly higher quantity, providing supply security.
