Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF7-3P-3.96DSA(25) is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 3 — connector must accommodate the same pin count
• Number of Rows: 1 — single-row configuration required
• Mounting Type: Through Hole — PCB mounting method must remain consistent
• Shrouding: Shrouded - 4 Wall — mechanical protection and keying alignment
• Style: Board to Cable/Wire — functional application category
• Termination: Solder — connection method to PCB

The substitute part 179839-1 (TE Connectivity AMP Connectors) meets all these critical parameters, enabling direct functional replacement in applications requiring the DF7-3P-3.96DSA(25) connector.

Parameter Comparison

Engineering Selection Recommendations

The 179839-1 (TE Connectivity AMP Connectors) is the qualified substitute for the obsolete DF7-3P-3.96DSA(25). Selection is based on the following factors:

• Product Status: The substitute part is Active, ensuring continued availability and supply chain reliability, whereas the original part is Obsolete.
• Compliance: Both parts carry UL94 V-0 flammability rating and share identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory consistency.
• Certification: The substitute part is RoHS3 Compliant, meeting current environmental standards.
• Critical Parameter Alignment: All essential mechanical and electrical parameters match the original specification, including pitch, position count, mounting type, shrouding, and termination method.
• Operating Temperature Range: The substitute part supports an extended operating temperature range (-30°C ~ 105°C) compared to the original (-35°C ~ 85°C), providing broader application flexibility.

Frequently Asked Questions (FAQ)

Q: Can the 179839-1 be used as a direct replacement for the DF7-3P-3.96DSA(25)?

A: Yes. Both connectors share identical pitch (0.156" / 3.96mm), position count (3), row configuration (1), mounting type (through hole), shrouding (4-wall), and termination method (solder). These parameters determine mechanical and electrical compatibility.

Q: What is the difference in contact type between these parts?

A: The DF7-3P-3.96DSA(25) uses male pin contacts, while the 179839-1 uses tab contacts. Both are compatible with standard mating connectors designed for 0.156" (3.96mm) pitch applications.

Q: Are there packaging differences between the original and substitute?

A: The original part packaging is not specified. The substitute part 179839-1 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the substitute part support the same operating temperature range?

A: The substitute part supports a wider operating temperature range (-30°C ~ 105°C) compared to the original (-35°C ~ 85°C). Applications requiring the original temperature range are fully supported by the substitute.

Q: What is the difference in insulation material?

A: The original uses Polyamide (PA) with glass filling, while the substitute uses Polyamide (PA66) Nylon 6/6. Both materials meet UL94 V-0 flammability requirements and are suitable for the same application categories.

Q: Is the substitute part RoHS compliant?

A: Yes. The 179839-1 is RoHS3 Compliant. The original part's RoHS status is not specified in the provided data.

Q: What is the current rating for these connectors?

A: Current rating information is not provided for the original part. The substitute part 179839-1 has a current rating that varies by wire gauge.
