L77DA15SAM4BRM6 Equivalent & Substitute Parts

Part Overview

The L77DA15SAM4BRM6 is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole, right-angle solder-mounted connector features female sockets, gold-plated contacts, and a tin-plated steel shell. The connector is designed for signal applications with a current rating of 7.5A and operates across a temperature range of -55°C to 125°C. The product status is Active, and it is RoHS compliant. Substitute parts are required when specific mounting configurations, contact ratings, or compliance requirements differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub receptacle connectors is determined by conformance to the following critical parameters:

• Connector Configuration: 15-position, 2-row D-Sub receptacle with female sockets
• Shell Size: Size 2 (DA, A) connector layout
• Mounting Style: Through-hole, right-angle orientation
• Termination Method: Solder connection
• Contact Material and Finish: Gold-plated contacts suitable for signal applications
• Electrical Ratings: Current and voltage capacity within or exceeding application requirements
• Environmental Compliance: RoHS and REACH certification status
• Operating Temperature Range: Compatibility with -55°C to 125°C specification

Substitute parts must satisfy these core parameters to ensure functional and mechanical interchangeability. Variations in backset spacing, contact current ratings below the primary specification, or non-compliant RoHS status affect substitutability based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

L77DA15SAM4BRM6 (Primary Part): This connector is the preferred selection for new designs. Active product status ensures ongoing availability and support. RoHS compliance meets environmental regulations for most commercial and industrial applications. The 7.5A current rating and full -55°C to 125°C operating range provide robust electrical performance across extended temperature extremes.

DA15S564GTLF (Amphenol ICC): This substitute is recommended when equivalent electrical performance and compliance are required. Both are manufactured by Amphenol ICC, share active product status, and offer RoHS compliance. The DA15S564GTLF provides identical voltage rating (300V) and temperature range (-55°C to 125°C). However, the current rating is 5A per contact versus 7.5A for the primary part, and packaging is bulk rather than tray. Backset spacing differs (0.409" versus 0.590"), which may impact PCB layout compatibility.

173-E15-211R141, 173-E15-211R241, 174-E15-211R141 (NorComp): These substitutes are available for legacy system maintenance only. All three are obsolete products with RoHS non-compliance status. Operating temperature range is limited to -50°C to 100°C, excluding low-temperature applications. Current ratings are reduced to 5A. Backset spacing varies significantly from the primary specification, affecting physical compatibility. Panel mount capability is an additional feature not present in the primary connector.

Frequently Asked Questions (FAQ)

Q: Can NorComp 173-E15 and 174-E15 series connectors directly replace the L77DA15SAM4BRM6 in new designs? A: No. The NorComp connectors are obsolete with RoHS non-compliance, narrower operating temperature range (-50°C to 100°C), and reduced current rating (5A). They are suitable only for legacy system repairs where original specifications cannot be altered.

Q: What is the primary difference between L77DA15SAM4BRM6 and DA15S564GTLF? A: Both are manufactured by Amphenol ICC with active status, RoHS compliance, and compatible shell size. Key differences include current rating (7.5A versus 5A per contact), contact finish specification (8.00µin thickness versus Flash), backset spacing (0.590" versus 0.409"), and packaging (tray versus bulk). DA15S564GTLF is a functional substitute where lower current capacity is acceptable.

Q: How does backset spacing affect substitution? A: Backset spacing determines the physical distance between the connector mounting surface and the mating face. Variations between 0.283" and 0.590" require PCB layout verification to ensure clearance and alignment. Substitution with different backset spacing may require design modifications.

Q: Are NorComp connectors electrically compatible with Amphenol ICC connectors? A: NorComp substitutes maintain D-Sub 15-position, 2-row configuration and solder termination compatibility. However, electrical parameter differences (current rating, operating temperature, voltage specification) and RoHS compliance status restrict their use to legacy applications where original specifications are documented and unchanged.

Q: Does packaging type affect connector functionality or interchangeability? A: Packaging type (tray versus bulk) does not affect connector functionality or mechanical/electrical interchangeability. Packaging affects handling, storage, and procurement logistics. Selection is based on application requirements, inventory management, and volume considerations.
