Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1647721 is determined by the following critical parameters:

• Connector Type & Series: Must be a female module within the HEAVYCON® M series
• Position Count: Must maintain 5 positions for mechanical and electrical compatibility
• Voltage & Current Ratings: Substitute must meet or exceed 600V and 16A specifications
• Operating Temperature: Must support -40°C to 125°C range
• Housing & Contact Materials: Polycarbonate housing with copper alloy contacts and silver finish ensure compatibility
• Flammability & Compliance: UL94 V-0 rating and RoHS compliance are required

The Phoenix Contact 1417373 qualifies as a direct substitute based on these parameters. While it employs push-in termination instead of tension clamp, it maintains all critical electrical and mechanical specifications, with enhanced current rating (19A) and active product status.

Engineering Selection Recommendations

The 1417373 is the qualified substitute for the obsolete 1647721. Selection should be based on the following factors:

Product Status: The 1417373 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete 1647721.

Compliance & Certifications: Both parts meet UL94 V-0 flammability requirements and RoHS standards. The 1417373 carries ROHS3 compliance, representing current regulatory alignment.

Electrical Performance: The 1417373 provides enhanced current capacity (19A versus 16A) while maintaining identical voltage rating (600V), offering improved margin for applications at or near the original 16A specification.

Termination Compatibility: The transition from tension clamp to push-in termination requires verification that the mating connector or wiring harness is compatible with push-in contact engagement. This is the primary consideration for substitution feasibility.

Environmental Specifications: Identical operating temperature range (-40°C to 125°C) and moisture sensitivity level (MSL 1) ensure equivalent performance in thermal and humidity conditions.

Frequently Asked Questions (FAQ)

Q: Can the 1417373 directly replace the 1647721 in existing assemblies?

A: Electrical and mechanical compatibility is confirmed across all critical parameters. However, the termination method differs (push-in versus tension clamp). Compatibility depends on whether the mating connector or wire termination method supports push-in engagement. Physical form factor and pin layout remain consistent within the HEAVYCON® M series.

Q: What is the significance of the current rating increase from 16A to 19A?

A: The 1417373 provides higher current capacity, which exceeds the original specification. This does not affect substitution eligibility; applications operating at or below 16A remain fully compatible. The higher rating provides additional design margin.

Q: Are there differences in packaging or availability?

A: The 1417373 is supplied in bulk packaging with 743 units currently in stock. The 1647721, being obsolete, has limited availability (1027 units in stock). For new designs or ongoing production, the 1417373 is the recommended selection.

Q: Does the color difference (gray on 1417373) affect electrical performance?

A: Color is a cosmetic attribute and does not impact electrical or mechanical function. Both parts use identical housing material (polycarbonate) and contact materials (copper alloy with silver finish).

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant and carry UL94 V-0 flammability rating. The 1417373 additionally carries REACH Unaffected status and ROHS3 compliance, reflecting current regulatory requirements.
