Substitute Part Grouping Explanation

Substitution eligibility for the L77DAH15SA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 15
• Number of Rows: 2
• Shell Size, Connector Layout: 2 (DA, A)
• Connector Style: D-Sub
• Termination: Solder
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Mounting Type: Through Hole, Right Angle (with or without Panel Mount capability)
• Flange Feature: Board Side or Mating Side configurations
• Shell Material Finish: Steel with different plating options (Tin Plated or Yellow Chromate Plated)
• Contact Finish: Gold with varying thickness specifications
• Current Rating: Minimum 5A (L77DAH15SA rated at 7.5A)
• Backset Spacing: Variations within connector geometry
• Operating Temperature Range: Minimum -50°C ~ 100°C (L77DAH15SA rated -55°C ~ 125°C)
• RoHS Status: Both compliant and non-compliant parts listed based on application requirements

The substitute parts 173-E15-211R141, 173-E15-211R241, 174-E15-211R141, and DA15S564GTLF meet the mandatory matching parameters and are therefore functionally equivalent within their specified electrical and mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: L77DAH15SA

The L77DAH15SA remains the recommended primary choice for new designs and applications requiring active product status, RoHS compliance, and extended operating temperature range (-55°C ~ 125°C). This part is currently in active production with adequate inventory availability.

Secondary Selection: DA15S564GTLF

The DA15S564GTLF serves as the preferred substitute when L77DAH15SA becomes unavailable. Both parts are manufactured by Amphenol ICC, share active product status, and maintain RoHS compliance. Both support the full operating temperature range of -55°C ~ 125°C and 300V voltage rating. The DA15S564GTLF features GXT™ gold contact finish and Board Lock mounting feature. Backset spacing differs (0.409" versus 0.319"), requiring PCB layout verification before substitution.

Tertiary Selection: 173-E15-211R141, 173-E15-211R241, 174-E15-211R141

The NorComp Inc. parts (173-E15-211R141, 173-E15-211R241, 174-E15-211R141) are classified as obsolete products and are not recommended for new designs. These parts are RoHS non-compliant and operate within a reduced temperature range (-50°C ~ 100°C). Current rating is limited to 5A compared to 7.5A for the L77DAH15SA. These parts are listed for reference only in applications where legacy component replacement is required and compliance restrictions do not apply.

Compliance Considerations:

Applications requiring RoHS compliance must use either L77DAH15SA or DA15S564GTLF. Applications with no RoHS requirement may utilize NorComp parts if temperature and current ratings are acceptable.

Temperature and Current Derating:

Applications operating above 100°C or requiring current ratings exceeding 5A per contact must use L77DAH15SA or DA15S564GTLF. NorComp parts are unsuitable for such applications.

Frequently Asked Questions (FAQ)

Q: Can the DA15S564GTLF directly replace the L77DAH15SA without PCB modification?

A: Both connectors share identical connector type, position count, shell size, and mounting style. However, backset spacing differs (0.409" for DA15S564GTLF versus 0.319" for L77DAH15SA). PCB layout verification is required before substitution to confirm mounting hole compatibility.

Q: Are the NorComp parts (173-E15-211R141, 173-E15-211R241, 174-E15-211R141) suitable for new product designs?

A: No. These parts carry obsolete product status and are RoHS non-compliant. They are listed for reference only in legacy system repairs or applications where compliance restrictions do not apply.

Q: What is the difference between 173-E15-211R141 and 173-E15-211R241?

A: Both parts are manufactured by NorComp Inc. with identical electrical and mechanical specifications. The primary difference is the flange feature: 173-E15-211R141 features Female Screwlock (4-40), while 173-E15-211R241 features Standard Screws (4-40). Backset spacing is identical at 0.283" (7.20mm).

Q: What is the difference between 173-E15-211R141 and 174-E15-211R141?

A: Both parts are manufactured by NorComp Inc. and share identical electrical specifications. The primary difference is backset spacing: 173-E15-211R141 has 0.283" (7.20mm) spacing, while 174-E15-211R141 has 0.370" (9.40mm) spacing. This difference affects PCB layout compatibility.

Q: Does the L77DAH15SA support panel mount applications?

A: The L77DAH15SA is specified for through-hole, right-angle mounting with board-side flange feature. It does not include panel mount capability. The NorComp alternatives (173-E15-211R141, 173-E15-211R241, 174-E15-211R141) support both panel mount and through-hole configurations.

Q: What is the significance of the contact finish thickness specification?

A: The L77DAH15SA specifies 8.00µin (0.203µm) gold contact finish thickness, while substitute parts specify flash thickness. Flash thickness is thinner and may affect contact durability in high-cycle mating applications. Applications requiring extended connector life should prioritize the L77DAH15SA or verify flash thickness adequacy for the specific use case.

Q: Are all listed parts compatible with the same mating connectors?

A: All parts share identical shell size (2 DA, A) and 15-position configuration, ensuring compatibility with standard D-Sub 15-position plugs. However, backset spacing variations (0.283", 0.319", 0.370", 0.409") may affect mechanical fit depending on the specific mating connector design.

Q: What packaging options are available?

A: The L77DAH15SA is supplied in tray packaging. The DA15S564GTLF is supplied in bulk packaging. NorComp parts are supplied in tray packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: Can the L77DAH15SA be used in applications exceeding 125°C?

A: No. The L77DAH15SA operating temperature range is specified as -55°C ~ 125°C. Applications requiring operation above 125°C require alternative connector designs outside the scope of this equivalency list.

Q: What is the current rating per contact for the DA15S564GTLF?

A: The DA15S564GTLF is rated at 5A per contact. The L77DAH15SA is rated at 7.5A total. Applications requiring current ratings exceeding 5A per contact should verify the specific current distribution across all 15 positions before substituting with the DA15S564GTLF.
