Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1687451 is determined by strict alignment with the following critical parameters:

• Series Compatibility: Part must belong to HEAVYCON® BB 18 series
• Connector Type: Insert without contacts configuration
• Gender: Female orientation
• Size Designation: B10 form factor
• Termination Method: Crimp termination style
• Electrical Ratings: 500V voltage and 16A current capacity minimum
• Contact Type: CK 2.5-ED specification
• Operating Temperature: -40°C to 125°C range
• Housing Material: Polycarbonate (PC)
• Flammability Compliance: UL94 V-0 rating
• Environmental Compliance: RoHS and MSL requirements

The substitute part 1687451 meets all these criteria with one functional enhancement: the addition of a ground position (18+Ground configuration), which maintains backward compatibility while providing additional grounding capability.

Engineering Selection Recommendations

The Phoenix Contact 1584729 is the direct substitute for the obsolete 1687451. Selection is based on the following engineering criteria:

Product Status: The 1687451 is classified as obsolete, while the 1584729 maintains active product status with current manufacturing support and availability.

Compliance Alignment: Both parts maintain equivalent electrical and mechanical specifications. The 1584729 carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS Compliant designation of the 1687451.

Functional Enhancement: The 1584729 incorporates an additional ground position (18+Ground) within the same B10 form factor and HEAVYCON® BB 18 series framework. This enhancement provides grounding capability without compromising dimensional or electrical compatibility with existing 18-position connector systems.

Certification Continuity: Both parts maintain UL94 V-0 flammability rating, identical voltage and current ratings, matching contact types, and equivalent operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the 1584729 directly replace the 1687451 in existing assemblies?

A: The 1584729 maintains full electrical and mechanical compatibility with the 1687451. Both parts share identical voltage ratings (500V), current ratings (16A), contact types (CK 2.5-ED), operating temperature ranges (-40°C to 125°C), and form factors (B10 size within HEAVYCON® BB 18 series). The primary difference is the addition of a ground position in the 1584729, which does not prevent substitution in applications designed for the 18-position configuration.

Q: What is the significance of the 18+Ground position configuration?

A: The 1584729 incorporates an additional dedicated ground position beyond the standard 18 positions. This provides enhanced grounding capability within the same connector footprint and series designation. Applications requiring only 18 signal positions can utilize the 1584729 without functional impact.

Q: Are there packaging differences between these parts?

A: The 1687451 is listed with unspecified packaging, while the 1584729 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: How do the RoHS compliance levels differ?

A: The 1687451 carries RoHS Compliant status, while the 1584729 carries ROHS3 Compliant status. ROHS3 represents the current regulatory standard and indicates the 1584729 meets the latest environmental compliance requirements.

Q: Are both parts suitable for the same operating temperature applications?

A: Both parts maintain identical operating temperature ranges of -40°C to 125°C, ensuring thermal compatibility across equivalent application environments.

Q: What is the significance of the UL94 V-0 flammability rating for both parts?

A: The UL94 V-0 rating indicates both parts meet the highest flammability classification standard, demonstrating material performance in fire safety testing. This rating is maintained across both the obsolete and active substitute parts.
