• Flammability Rating: UL94 V-0

Application-Specific Parameters:

• Mounting Type: Panel Mount, Through Hole, Right Angle
• Backset Spacing: 0.406" (10.30mm) for main part; 0.318" (8.08mm) for NorComp and Mercury substitutes
• Current Rating: 7.5A for main part; 5A or 3A for substitutes

Differences in backset spacing, current rating, voltage rating, and operating temperature range reflect design variations that may affect suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Highest Compatibility): The D09P33E4GV00LF (Amphenol ICC FCI) is the closest functional equivalent to the L77DFE09P1AON. Both parts share the same manufacturer family (Amphenol), identical 300V voltage rating, brass contact material, and comparable operating temperature range (-55°C ~ 125°C). This part maintains RoHS3 compliance and UL94 V-0 flammability rating. The 5A per contact current rating is lower than the main part's 7.5A specification.

Secondary Substitutes (NorComp Series): The NorComp parts (182-009-113R171, 182-009-113R531, 182-009-113R561) are functionally equivalent for applications requiring 5A current capacity. All three maintain the 9-position D-Sub configuration, solder termination, and UL94 V-0 rating. Differences include:

• 182-009-113R171: Ground Strap feature, lowest current rating (5A)
• 182-009-113R531: Board Lock feature, 5A current rating
• 182-009-113R561: Board Lock and Female Screwlock features, 5A current rating

All NorComp parts operate at -55°C ~ 105°C, which is narrower than the main part's range.

Alternative Substitute (Limited Application): The 621-009-260-042 (Mercury United Electronics) is suitable only for applications with current requirements of 3A per contact or lower. This part features Board Lock, Grounding Indents, Mounting Brackets, and Shielding. Operating temperature range is -55°C ~ 85°C, the most restrictive among all listed substitutes. Mounting type is Board Edge rather than Panel Mount.

Compliance Status: All substitute parts are RoHS3 compliant and carry UL94 V-0 flammability rating, matching the main part's compliance profile. The D09P33E4GV00LF is REACH Affected; all others are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 182-009-113R171 replace the L77DFE09P1AON in all applications?

A: The 182-009-113R171 is functionally compatible for applications requiring 5A or less current per contact. The main part's 7.5A rating exceeds the NorComp part's 5A capacity. Additionally, the NorComp part operates to 105°C maximum, compared to the main part's 155°C upper limit. Backset spacing differs (0.318" vs. 0.406"), which may affect mechanical fit in some panel configurations.

Q: What is the significance of backset spacing differences?

A: Backset spacing determines the distance from the connector's mating face to the solder cup or termination point. The L77DFE09P1AON has 0.406" (10.30mm) backset spacing, while most substitutes have 0.318" (8.08mm). This difference affects PCB layout and panel cutout dimensions. Substitution requires verification that the receiving application accommodates the different spacing.

Q: Are all substitute parts suitable for high-temperature applications?

A: No. The L77DFE09P1AON operates to 155°C, the D09P33E4GV00LF to 125°C, NorComp parts to 105°C, and the Mercury part to 85°C. Applications requiring operation above 105°C should use either the main part or the D09P33E4GV00LF. Applications limited to 85°C or below may use any listed substitute.

Q: What is the difference between the three NorComp substitute options?

A: All three NorComp parts (182-009-113R171, 182-009-113R531, 182-009-113R561) share identical electrical and thermal specifications (5A, -55°C ~ 105°C). Mechanical differences include:

• 182-009-113R171: Ground Strap and Grounding Indents
• 182-009-113R531: Board Lock and Grounding Indents
• 182-009-113R561: Board Lock, Female Screwlock (mating side), and Grounding Indents

Selection depends on mechanical retention and grounding requirements for the specific application.

Q: Is the Mercury 621-009-260-042 suitable for high-current applications?

A: No. The Mercury part is rated for 3A per contact, the lowest among all listed options. It is suitable only for signal-level applications or low-current circuits. The main part's 7.5A rating and the D09P33E4GV00LF's 5A rating are significantly higher.

Q: What packaging formats are available for these substitutes?

A: The L77DFE09P1AON is supplied in standard packaging (not specified). Substitute parts are available in:

• NorComp parts: Tray packaging
• Mercury part: Bulk packaging
• Amphenol FCI part: Tray packaging

Packaging format may affect order quantities and handling procedures.

Q: Are all parts RoHS compliant?

A: Yes. The L77DFE09P1AON is RoHS Compliant. All substitute parts are ROHS3 Compliant, which represents the current RoHS directive standard. REACH status varies: the D09P33E4GV00LF is REACH Affected; all others are REACH Unaffected.

Q: Can the D09P33E4GV00LF be used as a direct replacement?

A: The D09P33E4GV00LF is the most compatible substitute from an electrical and thermal perspective, sharing the same 300V voltage rating and comparable operating temperature range. However, the 5A per contact rating is lower than the main part's 7.5A. Backset spacing is 0.318" (8.08mm) versus the main part's 0.406" (10.30mm), requiring mechanical verification. Mounting type differs slightly (Through Hole, Right Angle vs. Panel Mount, Through Hole, Right Angle).
