Parameter Comparison

Engineering Selection Recommendations

The 1877285-8 is the recommended substitute for the obsolete DF7-8P-3.96DSA(26). Selection is based on the following engineering criteria:

Product Status: The DF7-8P-3.96DSA(26) is obsolete, while the 1877285-8 maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: Both connectors meet UL94 V-0 material flammability requirements and are REACH Unaffected. The 1877285-8 additionally carries ROHS3 compliance, meeting modern regulatory requirements for new designs and procurement.

Functional Compatibility: The connectors share identical critical parameters: 8-position configuration, 0.156" (3.96mm) pitch, through-hole solder termination, shrouded 4-wall design, and square contact geometry. These parameters ensure mechanical and electrical interchangeability in board-to-cable/wire applications.

Performance Envelope: The 1877285-8 operates across a wider temperature range (-25°C ~ 105°C versus -35°C ~ 85°C) and provides specified electrical ratings (7.5A at 250VAC), offering enhanced performance margins for industrial and general-purpose applications.

Material Differences: The substitute uses PBT glass-filled insulation instead of PA nylon, and tin-plated brass contacts instead of gold-plated copper alloy. These material changes are standard in modern connector design and do not affect functional compatibility for standard interconnection applications.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-8 directly replace the DF7-8P-3.96DSA(26) in existing designs?

A: Yes. Both connectors share identical pitch (0.156" / 3.96mm), position count (8), mounting method (through-hole solder), and shrouding configuration (4-wall). The mating interface and PCB footprint are compatible.

Q: What are the differences in contact finish between these connectors?

A: The DF7-8P-3.96DSA(26) uses gold-plated copper alloy contacts, while the 1877285-8 uses tin-plated brass contacts. Both finishes provide adequate corrosion resistance and electrical conductivity for standard interconnection applications. Tin plating is the industry standard for modern connector designs.

Q: Does the operating temperature range difference affect substitution?

A: The 1877285-8 supports a wider operating range (-25°C ~ 105°C) compared to the DF7-8P-3.96DSA(26) (-35°C ~ 85°C). For applications within the original temperature specification, the substitute performs equivalently. For applications requiring extended temperature operation, the 1877285-8 provides additional capability.

Q: Are there any compliance or regulatory considerations?

A: Both connectors meet UL94 V-0 flammability requirements and are REACH Unaffected. The 1877285-8 carries ROHS3 compliance, making it suitable for designs subject to modern environmental regulations. The DF7-8P-3.96DSA(26) compliance status for ROHS is not specified.

Q: What is the difference in insulation material?

A: The DF7-8P-3.96DSA(26) uses polyamide (PA) nylon glass-filled insulation, while the 1877285-8 uses polybutylene terephthalate (PBT) glass-filled insulation. Both materials provide equivalent electrical insulation properties and mechanical strength for this connector class.

Q: Are electrical ratings specified for the DF7-8P-3.96DSA(26)?

A: Current and voltage ratings are not specified for the DF7-8P-3.96DSA(26). The 1877285-8 is rated for 7.5A at 250VAC, providing a reference for typical application limits in this connector category.

Q: What is the packaging difference?

A: The DF7-8P-3.96DSA(26) packaging is not specified. The 1877285-8 is supplied in bulk packaging, standard for production procurement.
