Substitute Part Grouping Explanation

The DF7-7P-3.96DSA(26) can be substituted with the 1877285-7 (TE Connectivity AMP Connectors) based on the following critical parameters:

• Connector Type & Contact Configuration: Both are header connectors with male pin contacts
• Position Count & Pitch: Both feature 7 positions at 0.156" (3.96mm) mating pitch
• Row Configuration: Both are single-row designs
• Mounting & Termination: Both use through-hole mounting with solder termination
• Shrouding Design: Both incorporate shrouded 4-wall construction
• Contact Shape: Both use square contact geometry
• Flammability Compliance: Both meet UL94 V-0 rating
• Moisture Sensitivity: Both are MSL 1 (Unlimited)

The 1877285-7 is an active product with expanded operational specifications and improved availability, making it suitable for direct substitution in applications where the DF7-7P-3.96DSA(26) is no longer procurable.

Parameter Comparison

Engineering Selection Recommendations

The 1877285-7 is the recommended substitute for the obsolete DF7-7P-3.96DSA(26). Selection rationale is based on the following factors:

• Product Status: The DF7-7P-3.96DSA(26) is obsolete with limited remaining inventory. The 1877285-7 is an active product with substantial stock availability (75,845 pcs), ensuring long-term procurement viability.

• Compliance & Certification: Both parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The 1877285-7 additionally carries ROHS3 compliance, meeting current regulatory standards.

• Mechanical Compatibility: Both connectors share identical mating pitch (0.156"), position count (7), row configuration (1), mounting method (through-hole), and shrouding design (4-wall). PCB footprints are compatible.

• Electrical Specifications: The 1877285-7 provides defined electrical ratings (7.5A, 250VAC) compared to the unspecified ratings of the original part, offering improved design documentation for electrical validation.

• Operating Temperature: The 1877285-7 supports an expanded operating range (-25°C ~ 105°C) compared to the original (-35°C ~ 85°C), providing greater thermal margin in most applications.

Frequently Asked Questions (FAQ)

Q: Are the DF7-7P-3.96DSA(26) and 1877285-7 mechanically interchangeable?

A: Yes. Both connectors feature identical mating pitch (0.156"), 7-position single-row configuration, through-hole mounting, and shrouded 4-wall design. PCB footprints are compatible for direct substitution.

Q: What are the differences in contact materials and finishes?

A: The DF7-7P-3.96DSA(26) uses gold-plated copper alloy contacts, while the 1877285-7 uses tin-plated brass contacts. Both finishes provide adequate corrosion resistance for general-purpose applications. Contact material differences do not affect mechanical fit or mating performance.

Q: Does the 1877285-7 support the same operating temperature range?

A: The 1877285-7 supports a wider operating range (-25°C ~ 105°C) compared to the original part (-35°C ~ 85°C). This expanded range is suitable for applications within the original specification and extends capability for higher-temperature environments.

Q: Is the 1877285-7 RoHS compliant?

A: Yes. The 1877285-7 is ROHS3 compliant. The original DF7-7P-3.96DSA(26) RoHS status is not specified in available documentation.

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

A: The DF7-7P-3.96DSA(26) uses a latch holder fastening mechanism, while the 1877285-7 uses a locking ramp design. Both mechanisms provide secure mating and are functionally equivalent for board-to-cable/wire applications.

Q: Are electrical ratings specified for both parts?

A: The 1877285-7 provides defined electrical ratings (7.5A at 250VAC). The DF7-7P-3.96DSA(26) does not specify current or voltage ratings in available documentation. For applications requiring defined electrical specifications, the 1877285-7 offers improved design documentation.

Q: What is the packaging difference?

A: The DF7-7P-3.96DSA(26) packaging is not specified. The 1877285-7 is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.
