Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF7-9P-3.96DSA(26) is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be a header with male pin contacts
• Position Count & Row Configuration: Must maintain 9 positions in a single row
• Pitch Specification: Must match 0.156" (3.96mm) mating pitch
• Mounting & Termination: Must support through-hole mounting with solder termination
• Shrouding Design: Must feature shrouded 4-wall construction
• Application Style: Must support board-to-cable/wire connectivity
• Contact Geometry: Must use square contact shape
• Environmental Compliance: Must maintain UL94 V-0 flammability rating and MSL 1 classification

The substitute part 1877285-9 (TE Connectivity AMP Connectors) satisfies all critical substitution criteria, enabling direct functional replacement in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The 1877285-9 rectangular connector header from TE Connectivity AMP Connectors serves as the primary substitute for the obsolete DF7-9P-3.96DSA(26). Selection of this substitute is supported by the following factors:

Product Status: The DF7-9P-3.96DSA(26) is obsolete, while the 1877285-9 maintains active product status with current manufacturing availability (3089 pcs in stock versus 699 pcs for the original part).

Compliance & Certification: Both parts maintain UL94 V-0 flammability rating and MSL 1 classification. The 1877285-9 additionally carries ROHS3 compliance, meeting modern regulatory requirements.

Functional Equivalence: All critical connector parameters align: 9-position, single-row configuration; 0.156" (3.96mm) pitch; through-hole solder termination; shrouded 4-wall design; and board-to-cable/wire application style.

Environmental Performance: The 1877285-9 extends the operating temperature range to -25°C ~ 105°C, providing broader thermal capability compared to the original -35°C ~ 85°C specification.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-9 be used as a direct replacement for the DF7-9P-3.96DSA(26)?

A: Yes. Both connectors share identical critical specifications: 9-position header, 0.156" (3.96mm) pitch, through-hole solder termination, shrouded 4-wall construction, and square male pin contacts. Mechanical and electrical compatibility is established.

Q: What are the differences between these two connectors?

A: The primary differences are contact finish material (gold versus tin), contact base material (copper alloy versus brass), insulation material (polyamide versus PBT), and operating temperature range (-35°C ~ 85°C versus -25°C ~ 105°C). The 1877285-9 also includes ROHS3 compliance certification.

Q: Does the difference in contact finish affect compatibility?

A: Contact finish differences do not affect mechanical mating or basic electrical function. Both gold and tin finishes provide adequate conductivity for standard applications. Selection depends on specific corrosion resistance or contact resistance requirements of the end application.

Q: Are there packaging differences between these parts?

A: The DF7-9P-3.96DSA(26) packaging is not specified in available documentation. The 1877285-9 is supplied in bulk packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: What is the fastening type difference between these connectors?

A: The DF7-9P-3.96DSA(26) uses a latch holder fastening mechanism, while the 1877285-9 uses a locking ramp design. Both mechanisms provide secure mating and are compatible with standard board-to-cable/wire connection applications.

Q: Is the 1877285-9 suitable for high-temperature applications?

A: The 1877285-9 supports operating temperatures up to 105°C, compared to 85°C for the original part. This extended range may be beneficial for applications requiring higher thermal performance.
