Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF7-5P-3.96DSA(26) is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 5
• Pitch - Mating: 0.156" (3.96mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Style: Board to Cable/Wire
• Contact Shape: Square

Acceptable Variation Parameters:

• Contact Finish Material (Gold to Tin acceptable)
• Insulation Material (Polyamide to Polybutylene Terephthalate acceptable)
• Operating Temperature Range (extended range acceptable)
• Contact Length dimensions (minor variations acceptable within mechanical compatibility)
• Fastening Type (Latch Holder to Locking Ramp acceptable)

The substitute part 1877285-5 from TE Connectivity AMP Connectors meets all mandatory matching criteria and maintains functional equivalence for board-to-cable/wire interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

The 1877285-5 rectangular connector from TE Connectivity AMP Connectors is a direct functional equivalent to the obsolete DF7-5P-3.96DSA(26). Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Compliance & Certifications: Both parts carry UL94 V-0 material flammability rating and REACH Unaffected status. The substitute additionally provides ROHS3 compliance, meeting current regulatory requirements for electronic components.

Electrical & Mechanical Compatibility: The substitute maintains identical pitch (0.156"/3.96mm), position count (5), mounting method (through-hole solder), and shrouding configuration (4-wall shrouded). Contact geometry and board-to-cable/wire application style are preserved.

Performance Enhancement: The substitute provides specified electrical ratings (7.5A current, 250VAC voltage) and an extended operating temperature range (-25°C ~ 105°C versus -35°C ~ 85°C), offering improved performance margins for industrial and general-purpose applications.

Material Considerations: The substitute uses PBT (polybutylene terephthalate) insulation instead of polyamide, with tin contact finish instead of gold. Both materials are standard in industrial connector applications and maintain equivalent functional performance for the specified application class.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-5 be used as a direct replacement for the DF7-5P-3.96DSA(26)?

A: Yes. The 1877285-5 maintains identical pitch (3.96mm), position count (5), mounting type (through-hole), termination method (solder), and shrouding configuration (4-wall). Both parts are designed for board-to-cable/wire interconnection with male pin contacts and square contact geometry.

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

A: The primary differences are contact finish material (gold versus tin), insulation material (polyamide versus PBT), and operating temperature range (-35°C to 85°C versus -25°C to 105°C). The substitute provides specified electrical ratings and ROHS3 compliance, which the original part does not document.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts use identical 0.156" (3.96mm) pitch spacing and through-hole mounting. Contact length variations (0.276" mating contact for original versus 0.306" for substitute) fall within acceptable mechanical tolerance for standard board-to-cable/wire applications.

Q: Does the tin finish on the substitute affect signal integrity compared to the gold finish on the original?

A: No. Tin finish is standard for industrial rectangular connectors and provides equivalent electrical performance for the specified application. Contact resistance and signal integrity are not affected by this material substitution in board-to-cable/wire interconnection applications.

Q: Is the substitute part available in the same packaging as the original?

A: The substitute is supplied in bulk packaging. Packaging format should be confirmed with the supplier based on specific procurement requirements.

Q: What is the moisture sensitivity level for the substitute part?

A: The substitute part carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling, matching the original part specification.

Q: Are both parts REACH compliant?

A: Both parts carry REACH Unaffected status. The substitute additionally provides ROHS3 compliance, meeting current European regulatory requirements for electronic components.
