DF11G-8DP-2V(50) Equivalent & Substitute Parts

Part Overview

The DF11G-8DP-2V(50) is a surface mount rectangular connector header manufactured by Hirose Electric Co Ltd. This 8-position, 2-row connector with 2.00mm pitch is designed for board-to-board or cable applications requiring shrouded, detent-lock connections. The part is currently in Last Time Buy status, making identification of equivalent alternatives essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF11G-8DP-2V(50) is determined by the following critical parameters:

• Connector geometry: 8 positions, 2 rows, 2.00mm pitch (both mating and row spacing)
• Mounting configuration: Surface mount with solder termination
• Shrouding design: 4-wall shrouded housing for mechanical alignment
• Electrical ratings: 2A current capacity and 250V voltage rating
• Environmental compliance: UL94 V-0 flammability and RoHS compliance

The Molex 0878320820 (Milli-Grid 87832 series) meets these core substitution criteria through identical pitch, position count, row configuration, mounting type, shrouding style, and compliance certifications. Variations in fastening mechanism (detent lock vs. push-pull), contact shape (circular vs. square), and operating temperature range do not prevent functional substitution when the primary electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0878320820 is a direct functional substitute for the DF11G-8DP-2V(50). Both parts share identical pitch, position count, row spacing, mounting type, and shrouding configuration. Both meet UL94 V-0 flammability requirements and maintain MSL 1 moisture sensitivity ratings.

The Molex part offers extended operating temperature range (-55°C to 105°C versus -30°C to 85°C) and is currently in Active product status, providing superior long-term availability compared to the Hirose part's Last Time Buy designation. The Molex part achieves ROHS3 compliance, exceeding the RoHS compliance of the original part.

Differences in fastening mechanism (push-pull versus detent lock) and contact geometry (square versus circular) are secondary design variations that do not affect electrical or mechanical interface compatibility when mating with standard 2.00mm pitch receptacles.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0878320820 directly replace the DF11G-8DP-2V(50) on existing PCBs?

A: Yes. Both parts share identical pitch (2.00mm), position count (8), row configuration (2 rows), mounting type (surface mount), and shrouding design (4-wall). PCB footprints designed for the Hirose part will accommodate the Molex substitute without modification.

Q: What is the significance of the different fastening types (detent lock vs. push-pull)?

A: Fastening type determines the mating and unmating force profile. Detent lock provides positive mechanical retention through spring-loaded detents, while push-pull uses a sliding collar mechanism. Both provide secure connections; the choice depends on application-specific requirements for connection stability and ease of service.

Q: Does the extended operating temperature range of the Molex part affect compatibility?

A: No. The Molex part's extended range (-55°C to 105°C) is a superset of the Hirose part's range (-30°C to 85°C). Applications operating within the original temperature specification will function identically with the substitute.

Q: Are there any electrical performance differences between the parts?

A: The Hirose part specifies 2A current rating and 250V voltage rating. The Molex part does not specify these values in the provided data. For applications requiring explicit current or voltage ratings, electrical performance should be confirmed against the Molex datasheet.

Q: What does "Last Time Buy" status mean for the Hirose part?

A: Last Time Buy indicates the manufacturer will no longer accept new orders after a specified date. Existing inventory will be sold until depletion. The Molex 0878320820, with Active status, provides continuity for future procurement and design iterations.
