DF3DZ-7P-2H(51) Equivalent & Substitute Parts

Part Overview

The DF3DZ-7P-2H(51) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 7 positions at 0.079" (2.00mm) pitch. This connector is classified as discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement. The part serves board-to-board or cable interconnection applications requiring shrouded, push-pull fastening with solder termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3DZ-7P-2H(51) is determined by the following critical parameters:

• Connector Type & Contact Type: Header with Male Pin contacts
• Number of Positions & Pitch: 7 positions at 0.079" (2.00mm) mating pitch
• Mounting Configuration: Surface Mount, Right Angle orientation
• Shrouding: Shrouded - 4 Wall design
• Termination Method: Solder termination
• Operating Temperature Range: -55°C ~ 105°C minimum
• Material Flammability: UL94 V-0 compliance
• RoHS Compliance: RoHS Compliant status

The identified substitute parts maintain these core parameters while differing in secondary attributes such as fastening type, contact finish, current rating specifications, and packaging format.

Parameter Comparison

Engineering Selection Recommendations

DF3EA-7P-2H(51) (Hirose Electric Co Ltd)

This part is the primary direct equivalent within the Hirose DF3 series. It maintains identical mechanical and electrical specifications to the DF3DZ-7P-2H(51), including 7-position 2.00mm pitch, surface mount right-angle configuration, shrouded 4-wall design, and push-pull fastening. Both parts are RoHS Compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity. The DF3EA-7P-2H(51) is currently Active in product status with 991 pieces in stock, providing immediate availability. This substitute is recommended for applications requiring direct form-fit-function replacement without design modification.

SWR201-NRTN-S07-HM-BG (Sullins Connector Solutions)

This part provides cross-manufacturer substitution with matching core parameters: 7-position 2.00mm pitch header, surface mount right-angle mounting, shrouded 4-wall design, and solder termination. The SWR201 series is currently Active with 771 pieces in stock. Notable differences include detent lock fastening (versus push-pull), square contact shape (versus circular), tin contact finish (versus gold), and reduced operating temperature range (-25°C ~ 85°C versus -55°C ~ 105°C). Current rating is specified as 1A per contact. This substitute is suitable for applications where the reduced temperature range and lower current rating are acceptable, and where detent lock fastening is compatible with the mating connector design.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-7P-2H(51) be used as a direct replacement for DF3DZ-7P-2H(51)?

A: Yes. Both parts are from the Hirose DF3 series with identical pitch (2.00mm), position count (7), mounting type (surface mount right-angle), shrouding (4-wall), termination (solder), operating temperature range (-55°C ~ 105°C), and flammability rating (UL94 V-0). The primary difference is product status: DF3DZ is discontinued while DF3EA is active. No design modification is required.

Q: What are the limitations of using SWR201-NRTN-S07-HM-BG as a substitute?

A: The SWR201-NRTN-S07-HM-BG differs in three key areas: (1) Operating temperature range is reduced to -25°C ~ 85°C, making it unsuitable for applications requiring -55°C operation; (2) Current rating is 1A per contact versus 3A for the original part; (3) Fastening type is detent lock instead of push-pull, requiring verification of mating connector compatibility. Contact shape and finish also differ (square tin versus circular gold).

Q: Are all substitute parts RoHS compliant?

A: Yes. DF3EA-7P-2H(51) is RoHS Compliant, and SWR201-NRTN-S07-HM-BG is ROHS3 Compliant. Both meet RoHS requirements for new designs.

Q: What is the difference between push-pull and detent lock fastening?

A: Push-pull fastening (DF3DZ and DF3EA) uses a spring-loaded mechanism requiring manual push action to disconnect. Detent lock fastening (SWR201) uses a mechanical latch that must be released before disconnection. Mating connector design must be compatible with the fastening type selected.

Q: Can I use SWR201-NRTN-S07-HM-BG in high-temperature applications?

A: No. The SWR201-NRTN-S07-HM-BG operating temperature range is -25°C ~ 85°C, which does not support the -55°C ~ 105°C range of the original DF3DZ-7P-2H(51). For applications requiring extended temperature operation, use DF3EA-7P-2H(51).

Q: What is the packaging difference between these parts?

A: DF3DZ-7P-2H(51) packaging is not specified. DF3EA-7P-2H(51) is supplied in Tape & Reel (TR) format. SWR201-NRTN-S07-HM-BG is supplied in Tube format. Packaging selection may affect procurement quantity minimums and handling requirements.
