Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1740317-4 are identified based on strict electrical and mechanical parameter alignment within the Nector S SSL connector series. The substitution logic is based on the following critical parameters:

Electrical Compatibility:

• Voltage Rating: 250V
• Current Rating: 2.5A
• Operating Temperature Range: -40°C ~ 120°C

Mechanical Compatibility:

• Connector Type: Distributor
• Number of Positions: 7
• Style: Board to Cable/Wire
• Mounting Type: Free Hanging (In-Line)
• Housing Material: Polyamide (PA6), Nylon 6
• Contact Material: Copper Alloy
• Features: Keying HV-1
• Base Product Number: 1740317

Parts meeting all these parameters are classified as direct substitutes. The 1740317-2 satisfies all specified electrical and mechanical requirements and is therefore a valid equivalent for the obsolete 1740317-4.

Parameter Comparison

Engineering Selection Recommendations

The 1740317-2 is the direct substitute for the obsolete 1740317-4. Both connectors share identical electrical ratings (250V, 2.5A), mechanical configuration (7-position distributor, board-to-cable/wire), and thermal operating range (-40°C ~ 120°C). All critical functional parameters align without exception.

The 1740317-2 offers the following advantages:

Product Status: The 1740317-2 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the 1740317-4 is obsolete.

Compliance: The 1740317-2 is ROHS3 compliant, meeting current regulatory requirements for restricted substances. The 1740317-4 is listed as not applicable for RoHS status.

Availability: The 1740317-2 is available in bulk packaging with 907 units in stock, compared to the 1740317-4 with 758 units in stock and no future production.

The only non-functional difference is housing color (white for 1740317-2 versus black for 1740317-4). This distinction does not affect electrical performance, thermal characteristics, or mechanical compatibility. Selection between these parts should be based on application-specific color requirements and compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the 1740317-2 directly replace the 1740317-4 in existing designs?

A: Yes. The 1740317-2 is a direct functional equivalent. All electrical parameters (voltage, current, temperature range), mechanical specifications (connector type, position count, mounting style), and material composition are identical. The housing color difference does not affect electrical or thermal performance.

Q: What is the primary reason to transition from 1740317-4 to 1740317-2?

A: The 1740317-4 is obsolete and no longer in production. The 1740317-2 is an active product with ongoing manufacturer support and availability. Transitioning to the 1740317-2 ensures long-term component supply and compliance with current regulatory standards.

Q: Are there any compliance differences between these parts?

A: Yes. The 1740317-2 is ROHS3 compliant, meeting current environmental and safety regulations. The 1740317-4 is listed as not applicable for RoHS status. For applications subject to ROHS3 requirements, the 1740317-2 is the appropriate selection.

Q: Does the housing color difference affect connector performance?

A: No. Housing color is a cosmetic attribute and does not influence electrical performance, current-carrying capacity, voltage rating, or thermal characteristics. Selection should be based on application-specific visual identification requirements or design specifications.

Q: What is the packaging difference between these parts?

A: The 1740317-4 packaging is not specified in available documentation. The 1740317-2 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.

Q: Are both parts from the same manufacturer and series?

A: Yes. Both the 1740317-4 and 1740317-2 are manufactured by TE Connectivity AMP Connectors and belong to the Nector S series. They share the same base product number (1740317) and feature identical keying (HV-1).

Q: What are the electrical specifications for both connectors?

A: Both connectors are rated for 250V maximum voltage and 2.5A maximum current. Operating temperature range is -40°C to 120°C for both parts. These specifications are suitable for Solid State Lighting applications requiring reliable power distribution across 7 positions.
