• Number of Positions: 7
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Insulation Material: Polyamide (PA), Nylon

Secondary Compatibility Factors:

• Operating Temperature Range
• Current Rating
• RoHS Compliance
• Material Flammability Rating
• Contact Material and Finish

The substitute parts listed below maintain compatibility with these core parameters while offering alternatives in fastening type, packaging, and specific electrical ratings.

Engineering Selection Recommendations

DF3EA-7P-2H(21) (Hirose Electric Co., Ltd.)

This is the primary equivalent substitute for the DF3DZ-7P-2H(21). Both parts are from the same manufacturer and DF3 series, with identical pitch, position count, mounting configuration, and operating temperature range. The DF3EA-7P-2H(21) is currently active in production with higher inventory availability (3010 Pcs vs. 1119 Pcs). It includes solder retention feature and is available in Tape & Reel packaging suitable for automated assembly. RoHS compliance and UL94 V-0 flammability rating are maintained. This substitute is recommended for direct replacement in new designs and production continuity.

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

This substitute from Sullins Connector Solutions maintains the same pitch, position count, and mounting type. It features detent lock fastening instead of push-pull, and square contact shape instead of circular. The operating temperature range is reduced (-25°C ~ 85°C vs. -55°C ~ 105°C), and current rating is lower (1A per contact vs. 3A). Voltage rating is specified at 125V. This part is suitable for applications with less demanding thermal and current requirements. ROHS3 compliance and UL94 V-0 rating are maintained. Selection of this substitute requires confirmation that the reduced operating temperature range and current rating are acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-7P-2H(21) be used as a direct replacement for DF3DZ-7P-2H(21)?

A: Yes. Both parts share identical electrical and mechanical specifications including pitch, position count, mounting type, operating temperature range, and flammability rating. The DF3EA-7P-2H(21) is the recommended substitute due to active product status and higher inventory availability.

Q: What are the key differences between DF3EA-7P-2H(21) and SWR201-NRTN-S07-HM-BG?

A: The primary differences are: fastening type (push-pull vs. detent lock), contact shape (circular vs. square), operating temperature range (-55°C to 105°C vs. -25°C to 85°C), current rating (3A vs. 1A per contact), and voltage rating (not specified vs. 125V). The SWR201 is suitable only for applications within its reduced thermal and electrical specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. DF3EA-7P-2H(21) is RoHS Compliant, and SWR201-NRTN-S07-HM-BG is ROHS3 Compliant. Both meet current environmental compliance requirements.

Q: What packaging options are available for these substitutes?

A: DF3EA-7P-2H(21) is supplied in Tape & Reel (TR) packaging for automated assembly. SWR201-NRTN-S07-HM-BG is supplied in Tube packaging. Packaging selection depends on assembly process requirements.

Q: Can SWR201-NRTN-S07-HM-BG be used in applications requiring -55°C operation?

A: No. The SWR201-NRTN-S07-HM-BG operating temperature range is -25°C to 85°C, which does not support -55°C operation. Applications requiring the full -55°C to 105°C range must use DF3EA-7P-2H(21).

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures.
