L77DAH15SAM4BRM6 Equivalent & Substitute Parts

Part Overview

The L77DAH15SAM4BRM6 is a 15 Position D-Sub Receptacle connector manufactured by Amphenol ICC (Commercial Products), featuring female sockets in a right-angle, through-hole solder configuration. This connector is currently in active production status. Substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application compatibility needs where equivalent electrical and mechanical parameters are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L77DAH15SAM4BRM6 are assessed based on the following critical parameters that determine electrical and mechanical compatibility:

Primary Compatibility Criteria:

• 15 positions, 2-row D-Sub configuration with DA/A shell size
• Receptacle connector type with female sockets
• Right-angle through-hole mounting with solder termination
• 300V voltage rating and temperature range compatibility
• Contact finish (gold) and shell material specifications
• UL94 V-0 flammability rating

The substitute parts listed below meet the core electrical and physical requirements but may differ in specific attributes such as current rating, backset spacing, flange configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - L77DAH15SAM4BRM6 (Amphenol ICC Commercial Products): This is the original specified part, currently in active production. It meets all electrical and thermal requirements with RoHS compliance and the highest current rating of 7.5A among the listed parts. It is the preferred choice for new designs and standard procurement.

Alternative Selection - DA15S564GTLF (Amphenol ICC FCI): This part is functionally equivalent to the primary part, both manufactured by Amphenol ICC. It maintains active product status, RoHS compliance, 300V voltage rating, and identical operating temperature range (-55°C ~ 125°C). The current rating is 5A per contact. The primary mechanical difference is the flange configuration (housing/shell unthreaded versus board side). This part is suitable as a direct substitute where flange compatibility is maintained.

Conditional Substitutes - NorComp Series (173-E15-211R141, 173-E15-211R241, 174-E15-211R141): These three NorComp parts carry obsolete product status and are RoHS non-compliant. They exhibit reduced current ratings (5A), narrower operating temperature range (-50°C ~ 100°C), and unspecified voltage ratings. Backset spacing differs significantly from the primary part, requiring mechanical re-qualification. These parts are not recommended for new applications or designs requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I substitute the L77DAH15SAM4BRM6 with the DA15S564GTLF? A: The DA15S564GTLF is electrically and mechanically compatible within most applications. Both parts maintain identical shell size (DA/A), 15-position 2-row configuration, right-angle through-hole solder mounting, RoHS compliance, and 300V/(-55°C ~ 125°C) specifications. However, the flange configuration differs (housing/shell unthreaded vs. board side), requiring verification of PCB mounting hole patterns before substitution.

Q: Why are the NorComp parts listed as substitutes if they are obsolete? A: The NorComp parts (173-E15-211R141, 173-E15-211R241, 174-E15-211R141) are listed based on the original part's documented substitute list. However, their obsolete status and RoHS non-compliance make them unsuitable for current applications. New designs should not utilize these parts.

Q: What is the significance of backset spacing differences? A: Backset spacing defines the distance from the flange to the mating face of the connector. The L77DAH15SAM4BRM6 specifies 0.590" (14.99mm), while substitutes range from 0.283" to 0.409". This parameter directly affects PCB layout and enclosure fit. Parts with different backset spacing require mechanical re-qualification and may not be pin-compatible in existing designs.

Q: Are there current rating limitations I should consider? A: The primary part (L77DAH15SAM4BRM6) supports 7.5A, while the Amphenol ICC alternative (DA15S564GTLF) and all NorComp substitutes support only 5A per contact. Applications requiring full 7.5A capacity must use the primary part. Lower-current applications (≤5A per contact) may utilize any substitute.

Q: What is the difference between the NorComp 173-E and 174-E series? A: Both series share identical electrical specifications (15-position, 2-row D-Sub receptacle) but differ in backset spacing: 173-E series at 0.283" (7.20mm) and 174-E series at 0.370" (9.40mm). The 174-E series also specifies brass contact material, while 173-E series contact material is unspecified. Neither series is recommended due to obsolete status.

Q: Is RoHS compliance a factor in my selection? A: RoHS compliance is mandatory for certain regulatory jurisdictions and applications. The L77DAH15SAM4BRM6 and DA15S564GTLF are RoHS compliant. All NorComp substitutes are RoHS non-compliant and must not be used in applications requiring RoHS certification.
