Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the DF7-2P-3.96DSA(25) is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical and electrical alignment
• Number of Positions: 2 — connector must accommodate the same pin count
• Connector Type: Header — must be a header configuration for board-to-cable/wire connection
• Mounting Type: Through Hole — must support through-hole PCB mounting
• Shrouding: Shrouded - 4 Wall — must provide equivalent mechanical protection and keying
• Termination: Solder — must support solder termination for PCB assembly
• Material Flammability Rating: UL94 V-0 — must meet or exceed flame resistance requirements

The substitute part 179838-1 (TE Connectivity AMP Connectors) satisfies all critical substitution parameters. Both connectors share identical pitch, position count, header type, through-hole mounting, shrouded design, solder termination capability, and UL94 V-0 flammability rating.

Parameter Comparison

Engineering Selection Recommendations

The 179838-1 (TE Connectivity AMP Connectors) is a direct substitute for the obsolete DF7-2P-3.96DSA(25). Both connectors meet identical electrical and mechanical specifications for the critical substitution parameters: pitch, position count, mounting type, shrouding configuration, and termination method.

The substitute part offers the following advantages:

• Active Product Status: 179838-1 is currently in active production, ensuring long-term availability and supply chain continuity
• Enhanced Operating Temperature Range: The substitute supports -30°C ~ 105°C versus the original -35°C ~ 85°C, providing broader thermal operating capability
• RoHS3 Compliance: 179838-1 is RoHS3 compliant, meeting current environmental and regulatory standards
• Improved Inventory Availability: 2040 units in stock versus 989 units for the obsolete original part

Both connectors carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, confirming equivalent reliability and environmental performance.

Frequently Asked Questions (FAQ)

Q: Can 179838-1 be used as a direct replacement for DF7-2P-3.96DSA(25)?

A: Yes. Both connectors share identical pitch (0.156" / 3.96mm), position count (2), mounting type (through hole), shrouding (4-wall), and termination method (solder). They are mechanically and electrically compatible for board-to-cable/wire applications.

Q: What are the key differences between these two connectors?

A: The primary differences are contact type (male pin versus tab), insulation material composition (PA glass-filled versus PA66), operating temperature range (-35°C to 85°C versus -30°C to 105°C), and product status (obsolete versus active). The substitute offers a wider operating temperature range and active production status.

Q: Does the substitute part require any PCB layout modifications?

A: No. Both connectors use identical 0.156" (3.96mm) pitch and through-hole mounting, requiring no changes to PCB footprint or layout.

Q: What is the packaging difference?

A: The original DF7-2P-3.96DSA(25) packaging is not specified. The substitute 179838-1 is supplied in tray packaging.

Q: Are both connectors RoHS compliant?

A: The original part's RoHS status is not specified. The substitute 179838-1 is RoHS3 compliant, meeting current environmental regulations.

Q: What is the inventory status for each part?

A: DF7-2P-3.96DSA(25) has 989 units in stock (obsolete status). 179838-1 has 2040 units in stock (active production).
