Substitute Part Grouping Explanation

The DF7-7P-3.96DSA(25) 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
• Mounting & Termination: Both use through-hole mounting with solder termination
• Shrouding & Style: Both employ shrouded 4-wall construction for board-to-cable/wire applications
• Contact Shape & Material: Both use square-shaped contacts with tin finish
• Flammability Compliance: Both meet UL94 V-0 material flammability rating
• Moisture Sensitivity: Both are MSL 1 (Unlimited)

The 1877285-7 is an active product with expanded operating temperature range (-25°C ~ 105°C) and includes electrical ratings (7.5A at 250VAC), making it suitable for applications requiring the DF7-7P-3.96DSA(25) footprint and functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 1877285-7 is the recommended substitute for the obsolete DF7-7P-3.96DSA(25). Selection is based on:

• Product Status: The 1877285-7 is an active product with current manufacturing support, whereas the DF7-7P-3.96DSA(25) is obsolete and subject to availability constraints.
• Compliance & Certification: Both parts maintain UL94 V-0 flammability compliance and REACH Unaffected status, ensuring regulatory alignment.
• Functional Equivalence: Matching connector type, position count, pitch, mounting method, and shrouding ensure mechanical and electrical compatibility in existing designs.
• Enhanced Operating Range: The 1877285-7 provides an expanded operating temperature range (-25°C ~ 105°C) compared to the original part (-35°C ~ 85°C), offering greater thermal flexibility for industrial and general-purpose applications.
• Electrical Ratings: The 1877285-7 includes specified electrical ratings (7.5A at 250VAC), providing documented performance parameters for circuit design validation.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-7 be used as a direct replacement for the DF7-7P-3.96DSA(25)?

A: Yes. Both connectors share identical mating pitch (0.156"), position count (7), mounting type (through-hole), termination method (solder), and shrouding configuration (4-wall). The mechanical footprint and electrical interface are compatible.

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

A: The primary differences are contact material (copper alloy vs. brass), insulation material (polyamide vs. PBT), operating temperature range (-35°C to 85°C vs. -25°C to 105°C), and insulation color (beige vs. white). The 1877285-7 includes specified electrical ratings (7.5A at 250VAC) and RoHS3 compliance, whereas the DF7-7P-3.96DSA(25) is obsolete.

Q: Are there any compatibility concerns with PCB layout or mating connectors?

A: No. The 0.156" (3.96mm) pitch and 7-position configuration are standardized for this connector family. Existing mating connectors and PCB layouts designed for the DF7-7P-3.96DSA(25) will accommodate the 1877285-7 without modification.

Q: Does the change in insulation material affect performance?

A: Both polyamide and PBT are glass-filled thermoplastics with UL94 V-0 flammability ratings. PBT offers slightly different mechanical and thermal properties but maintains functional equivalence for board-to-cable/wire applications within the specified operating ranges.

Q: What is the availability status of each part?

A: The DF7-7P-3.96DSA(25) is obsolete with limited remaining inventory (1022 pcs). The 1877285-7 is an active product with substantial current inventory (75845 pcs), ensuring reliable procurement for new designs and production requirements.
