Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L77DA15SF179A is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish functional equivalence:

Critical Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 15 positions
• Row configuration: 2 rows
• Shell size and layout: Size 2 (DA, A)
• Mounting method: Panel mount, through-hole
• Termination: Wire wrap
• Flange type: Unthreaded housing/shell
• Operating temperature range: -55°C to 125°C minimum

Acceptable Variation Parameters:

• Voltage rating: Substitute must meet or exceed 300V
• Current rating: Substitute must support 7.5A per contact minimum
• Contact finish composition: Gold or equivalent noble metal finishes
• Shell material: Steel with tin or equivalent corrosion-resistant plating
• Compliance certifications: RoHS and REACH status may differ

The substitute part DAP15S465TLF meets all critical matching parameters and acceptable variation criteria, establishing it as a valid equivalent for the L77DA15SF179A in applications where the specified electrical and mechanical requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (L77DA15SF179A): Select the L77DA15SF179A when procurement from the Commercial Products division is preferred or when existing inventory supports immediate delivery. This part maintains RoHS compliance and is actively manufactured with 1034 units in stock.

Substitute Part Selection (DAP15S465TLF): The DAP15S465TLF serves as a direct functional equivalent and may be selected based on the following criteria:

• Supply chain availability: 1432 units in current inventory provide enhanced procurement flexibility
• Enhanced electrical performance: 1000V voltage rating exceeds the 300V requirement, providing additional safety margin in applications subject to transient voltage conditions
• Improved contact durability: GXT™ gold plating at 30.0µin thickness provides extended contact life compared to the 8.00µin thickness of the primary part
• Compliance: ROHS3 compliance meets current regulatory requirements; REACH Affected status requires verification against specific substance restrictions in the application jurisdiction

Interchangeability Confirmation: Both connectors are mechanically and electrically interchangeable within applications requiring 15-position D-Sub receptacles with panel mount, through-hole wire wrap termination, operating within -55°C to 125°C temperature range, and rated for 7.5A at 300V minimum.

Frequently Asked Questions (FAQ)

Q: Can DAP15S465TLF replace L77DA15SF179A in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, pin configurations, mounting methods, and termination techniques. The DAP15S465TLF meets or exceeds all electrical specifications of the L77DA15SF179A, including current and voltage ratings.

Q: What is the difference in contact finish between these parts?

A: The L77DA15SF179A features 8.00µin (0.203µm) gold plating, while the DAP15S465TLF features 30.0µin (0.76µm) GXT™ gold plating. The thicker plating on the substitute part provides enhanced resistance to wear and corrosion in high-cycle mating applications.

Q: Are there voltage rating differences, and does this affect compatibility?

A: The L77DA15SF179A is rated for 300V, while the DAP15S465TLF is rated for 1000V. The substitute part exceeds the primary part's voltage specification, making it suitable for applications requiring higher voltage margins. No design modification is required.

Q: What is the difference between RoHS and ROHS3 compliance?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances Directive. ROHS3 Compliant indicates compliance with the updated directive (2011/65/EU as amended). Both certifications restrict the same hazardous substances; ROHS3 represents the current regulatory standard.

Q: Does the REACH Affected status of DAP15S465TLF create compatibility issues?

A: REACH Affected status indicates the part contains substances regulated under the REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulation. Compatibility depends on the application jurisdiction and specific substance restrictions. Verify REACH compliance requirements for your target market before final part selection.

Q: Are both parts suitable for wire wrap termination?

A: Yes. Both the L77DA15SF179A and DAP15S465TLF feature wire wrap termination. Wire wrap tooling and procedures are identical for both connectors.

Q: What is the difference in contact material between brass and copper alloy?

A: The L77DA15SF179A uses brass contacts, while the DAP15S465TLF uses copper alloy contacts. Both materials provide equivalent electrical conductivity and corrosion resistance when combined with gold plating. The copper alloy in the substitute part may offer slightly improved spring characteristics.

Q: Can these connectors be used interchangeably in the same PCB or panel design?

A: Yes. Both connectors use identical shell sizes (Size 2, DA/A layout), mounting hole patterns, and through-hole dimensions. No design modifications to PCBs, panels, or mounting hardware are required for substitution.

Q: What is the operating temperature range for both parts?

A: Both connectors operate across -55°C to 125°C. This range is identical and suitable for industrial and commercial applications requiring extended temperature performance.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply to both connectors.
