Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-8P-2.54DS(55) is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (8)
• Pitch specification (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Current and voltage ratings (3A, 250V minimum)
• Operating temperature range (-35°C ~ 85°C minimum)
• Material compliance (UL94 V-0, RoHS Compliant)

The MDF7-8P-2.54DS(95) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the MDF7 series.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-8P-2.54DS(95) is the qualified substitute for the obsolete MDF7-8P-2.54DS(55). Both connectors maintain identical electrical specifications (3A, 250V), mechanical configuration (8-position, 2.54mm pitch, through-hole right-angle), and material compliance (UL94 V-0, RoHS Compliant).

The primary distinction is product status: MDF7-8P-2.54DS(95) is active and currently available, while MDF7-8P-2.54DS(55) is obsolete. The contact length variance (0.292" versus 0.293" mating contact) is within acceptable tolerance for board-to-board applications and does not affect functional compatibility.

Selection of MDF7-8P-2.54DS(95) ensures continued supply availability and maintains full compliance with the original design specifications.

Frequently Asked Questions (FAQ)

Q: Are MDF7-8P-2.54DS(55) and MDF7-8P-2.54DS(95) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.54mm), position count (8), mounting type (through-hole right-angle), and insulation dimensions (0.157" height). The mating contact length difference (0.001") is within standard tolerance and does not affect board-level compatibility.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and packaging. MDF7-8P-2.54DS(55) is obsolete; MDF7-8P-2.54DS(95) is active and available. MDF7-8P-2.54DS(95) is supplied in bag packaging. Both maintain identical electrical ratings and material specifications.

Q: Can MDF7-8P-2.54DS(95) be used as a direct replacement in existing designs?

A: Yes. The substitute part meets or exceeds all electrical (3A, 250V), thermal (-35°C ~ 85°C), and compliance requirements (UL94 V-0, RoHS) of the original specification. No design modification is required.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS Compliant, UL94 V-0 rated, and carry identical moisture sensitivity level (MSL 1). Compliance certifications are equivalent.

Q: What is the inventory status of the substitute part?

A: MDF7-8P-2.54DS(95) has 617 pieces in stock as new original inventory, ensuring supply continuity for production requirements.
