L777DFE09PAM4B D-Sub Plug Connector Equivalent & Substitute Parts

Part Overview

The L777DFE09PAM4B is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This right-angle solder connector is designed for panel mount and through-hole applications with male pins in a 2-row configuration. The connector is currently in active production status with 1023 pieces in stock inventory.

Equivalent and substitute parts are identified when design requirements, supply chain constraints, or manufacturing discontinuation necessitate component replacement. Substitutes must maintain compatibility across connector style, pin count, mounting type, and electrical ratings to ensure functional equivalence in the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L777DFE09PAM4B is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector style: D-Sub
• Connector type: Plug with male pins
• Position count: 9 positions
• Row configuration: 2 rows
• Shell size and layout: 1 (DE, E)
• Mounting type: Right angle with through-hole capability
• Termination method: Solder

Secondary Compatibility Criteria:

• Current rating: Minimum 5A per contact (L777DFE09PAM4B rated 7.5A)
• Voltage rating: Minimum 300V
• Operating temperature range: Must encompass application requirements
• Flammability rating: UL94 V-0 compliance
• RoHS compliance status: Active or ROHS3 compliant

The three substitute parts identified (09661627816, DE09P564CTXLF, DE09P565CTXLF) meet the primary compatibility criteria. Secondary parameter variations exist and are documented in the comparison table below.

Parameter Comparison

Engineering Selection Recommendations

L777DFE09PAM4B (Primary Part): Select this part when the full operating temperature range of -55°C to 155°C is required and current capacity of 7.5A per connector is specified. RoHS compliance is confirmed. This part includes panel mount capability in addition to through-hole mounting.

09661627816 (HARTING Substitute): This substitute is functionally equivalent for applications operating within -55°C to 125°C temperature range. Current rating matches at 7.5A. ROHS3 compliance is confirmed. Note that panel mount capability is not specified for this variant. Select when HARTING supply chain preference or cost optimization is a factor.

DE09P565CTXLF (Amphenol ICC FCI Substitute): This substitute maintains 300V voltage rating and operates within -55°C to 125°C range. Current rating is 5A, which is lower than the primary part. ROHS3 compliance is confirmed. Contact finish includes GXT™ technology with 30.0µin thickness matching the primary part. Select when FCI product line standardization is required and 5A current capacity is sufficient for the application.

DE09P564CTXLF (Amphenol ICC FCI Substitute): This substitute operates within -55°C to 125°C range with 5A per contact current rating. Contact finish is Gold with GXT™ technology but specified as flash thickness. ROHS compliance is confirmed. Backset spacing differs at 0.409" versus 0.590" on the primary part. Select only when mechanical layout accommodates the reduced backset spacing and 5A current capacity is acceptable.

Frequently Asked Questions (FAQ)

Q: Can DE09P564CTXLF and DE09P565CTXLF be used interchangeably with L777DFE09PAM4B?

A: Both parts are mechanically and electrically compatible as D-Sub 9-position plugs with right-angle solder termination. However, the current rating is reduced to 5A compared to 7.5A on the primary part. Additionally, backset spacing on DE09P564CTXLF is 0.409" versus 0.590" on L777DFE09PAM4B, which may affect panel cutout dimensions. Verify application current requirements and mechanical layout before substitution.

Q: What is the difference between 09661627816 and the Amphenol ICC FCI substitutes?

A: 09661627816 is manufactured by HARTING and maintains the 7.5A current rating of the primary part. The Amphenol ICC FCI substitutes (DE09P564CTXLF and DE09P565CTXLF) reduce current capacity to 5A. All three substitutes operate within -55°C to 125°C, which is narrower than the primary part's -55°C to 155°C range. Contact finish specifications also vary across the three options.

Q: Does operating temperature range affect substitution eligibility?

A: Yes. The primary part L777DFE09PAM4B operates from -55°C to 155°C. All three substitutes operate from -55°C to 125°C. If the application requires operation above 125°C, substitution is not permissible. Verify the maximum operating temperature requirement before selecting a substitute part.

Q: Are all substitute parts RoHS compliant?

A: Yes. L777DFE09PAM4B is RoHS Compliant. 09661627816 and DE09P565CTXLF are ROHS3 Compliant. DE09P564CTXLF is RoHS Compliant. All parts meet RoHS requirements for new designs.

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

A: Contact finish thickness affects durability and wear resistance. L777DFE09PAM4B and DE09P565CTXLF both specify 30.0µin (0.76µm) gold plating. DE09P564CTXLF specifies flash thickness, which is thinner and may have reduced durability in high-cycle mating applications. 09661627816 does not specify contact finish thickness. For applications with frequent mating cycles, prefer parts with 30.0µin specification.

Q: Can I use these substitutes if my design specifies panel mount capability?

A: L777DFE09PAM4B explicitly includes panel mount capability. The three substitutes specify through-hole right-angle mounting but do not explicitly list panel mount. If panel mount is a functional requirement, verify mechanical compatibility with the substitute part's flange feature before substitution. 09661627816 features a 4-40 threaded flange, while DE09P564CTXLF and DE09P565CTXLF feature unthreaded housings.
