Phoenix Contact 1735642 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1735642 is a 10-position terminal block header with male pins, shrouded on four sides, designed for 90° right-angle through-hole mounting. This component operates at 12A (IEC) and 250V (IEC) with 5.00mm pitch spacing. The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1735642 is determined by strict equivalence in the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 10 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Configuration: Male pins with 4-side shrouding and 90° right-angle orientation are mandatory for form-factor compatibility.
• Termination & Mounting: Solder termination and through-hole mounting must be preserved for assembly process compatibility.
• Electrical Ratings: Current and voltage ratings must meet or exceed the original specification to ensure safe operation within the same circuit environment.
• Compliance: RoHS compliance status must be maintained for regulatory alignment.

The Phoenix Contact 1836654 qualifies as a direct substitute based on these parameters. It maintains identical mechanical configuration, position count, pitch, and mounting style while offering enhanced electrical ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1836654 is the appropriate substitute for the obsolete 1735642 based on the following engineering criteria:

Mechanical Compatibility: Both parts share identical position count (10), pitch spacing (5.00mm), header configuration (male pins, 4-side shrouded), and mounting orientation (90° right-angle through-hole). This ensures direct compatibility with existing PCB layouts and mating connectors.

Electrical Adequacy: The 1836654 meets or exceeds the original electrical specifications. IEC ratings of 12A at 320V exceed the 1735642's 250V specification. UL ratings of 16A at 300V provide additional certification coverage for North American applications.

Product Status & Compliance: The 1836654 holds active product status, ensuring long-term availability and supply chain stability. Both parts maintain RoHS compliance. The 1836654 provides additional UL94 V-0 flammability certification and specifies material composition (Liquid Crystal Polymer housing, Copper Alloy contacts), supporting design documentation and regulatory requirements.

Thermal Performance: The 1836654 specifies operating temperature range (-40°C to 100°C), providing defined thermal operating boundaries absent in the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the 1836654 be used as a direct replacement for the 1735642 in existing designs?

A: Yes. Both parts maintain identical mechanical configuration (10 positions, 5.00mm pitch, 90° right-angle, male pins, 4-side shrouded, through-hole solder termination). The 1836654 provides equal or superior electrical ratings and active product status.

Q: What are the key differences between these parts?

A: The primary differences are product status (1735642 is obsolete; 1836654 is active), voltage rating (250V vs. 320V IEC), and material specifications. The 1836654 includes UL94 V-0 flammability rating, specified housing material (LCP), and contact material (Copper Alloy), with defined operating temperature range (-40°C to 100°C).

Q: Are there packaging differences?

A: The 1735642 packaging is not specified in available data. The 1836654 is supplied in Tape & Reel (TR) packaging, standard for automated assembly processes.

Q: Do these parts require different PCB footprints?

A: No. Identical pitch (5.00mm), position count (10), and mounting type (through-hole) ensure the same PCB footprint compatibility.

Q: Is the 1836654 suitable for high-temperature applications?

A: The 1836654 specifies operating temperature range of -40°C to 100°C. Applications requiring operation beyond this range require separate thermal analysis.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1735642 and 1836654 maintain RoHS compliance status.
