DF7-8P-3.96DSA(25) Equivalent & Substitute Parts

Part Overview

The DF7-8P-3.96DSA(25) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting with 8 positions at 0.156" (3.96mm) pitch. This connector features a shrouded 4-wall design with solder termination and latch holder fastening, suitable for board-to-cable/wire applications. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF7-8P-3.96DSA(25) is determined by strict alignment of the following electrical and mechanical parameters:

• Connector type (Header) and contact type (Male Pin)
• Pitch specification (0.156" / 3.96mm)
• Position count (8 positions, single row)
• Mounting method (Through Hole)
• Termination type (Solder)
• Application style (Board to Cable/Wire)
• Shrouding configuration (4-wall minimum)
• Contact material and finish (Tin-plated)
• Flammability compliance (UL94 V-0)

The two substitute parts listed—1877285-8 (TE Connectivity) and B8P-VH-FB-B (JST)—meet these core substitution criteria. Variations in contact length, insulation height, fastening mechanism, and operating temperature range do not prevent functional substitution when the primary mating and mounting parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the original DF7-8P-3.96DSA(25).

1877285-8 (TE Connectivity AMP Connectors): This part maintains full 4-wall shrouding and extends the operating temperature range to 105°C. It carries ROHS3 compliance and provides higher current rating (7.5A) and voltage rating (250VAC) specifications. Contact material is brass rather than copper alloy. This substitute is suitable for applications requiring extended temperature performance and higher electrical ratings.

B8P-VH-FB-B (JST Sales America Inc.): This part features reduced shrouding (1-wall) and maintains the original operating temperature ceiling of 85°C. It carries ROHS3 compliance and provides higher current rating (10A) and voltage rating (250V). Contact material is copper alloy, matching the original. This substitute is suitable for applications where shrouding reduction is acceptable and higher current capacity is beneficial.

Both parts satisfy core substitution criteria: identical pitch, position count, mounting method, and termination type. Selection between them depends on specific application requirements regarding shrouding configuration, temperature range, and electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the 1877285-8 and B8P-VH-FB-B be used interchangeably with the DF7-8P-3.96DSA(25)?

A: Both parts meet the core mating and mounting specifications (0.156" pitch, 8 positions, through-hole solder termination, board-to-cable/wire style). However, they differ in shrouding configuration and operating temperature range. The 1877285-8 maintains 4-wall shrouding; the B8P-VH-FB-B has 1-wall shrouding. Application-specific requirements determine which substitute is appropriate.

Q: What is the significance of shrouding differences between the substitutes?

A: The original DF7-8P-3.96DSA(25) and the 1877285-8 both feature 4-wall shrouding, which provides greater mechanical protection and alignment during mating. The B8P-VH-FB-B uses 1-wall shrouding, reducing physical profile but offering less mechanical constraint. This difference affects board layout and connector alignment requirements.

Q: Are there compliance differences between the substitutes?

A: The original part carries no RoHS status designation. Both substitutes are ROHS3 compliant and REACH unaffected. All three parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level.

Q: How do contact material differences affect substitution?

A: The original DF7-8P-3.96DSA(25) and B8P-VH-FB-B use copper alloy contacts; the 1877285-8 uses brass contacts. Both materials are tin-plated and suitable for solder termination. Material selection does not prevent functional substitution when all other electrical and mechanical parameters align.

Q: What are the electrical rating differences?

A: The original part does not specify current or voltage ratings. The 1877285-8 is rated for 7.5A at 250VAC. The B8P-VH-FB-B is rated for 10A at 250V. Applications requiring specific electrical ratings should select the substitute that meets or exceeds those requirements.

Q: Does operating temperature range affect substitution suitability?

A: The original part operates from -35°C to 85°C. The 1877285-8 extends to 105°C; the B8P-VH-FB-B maintains the 85°C upper limit. Applications operating below -25°C or above 85°C require the 1877285-8. For standard industrial temperature ranges (-25°C to 85°C), both substitutes are suitable.
