Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7P-26DP-2.54DSA(55) is determined by the following critical parameters:

• Connector type (Header)
• Number of positions (26)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Contact type (Male Pin)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (3A)
• Voltage rating (250V)
• Operating temperature range (-35°C ~ 85°C)
• Material compliance (RoHS Compliant, UL94 V-0)

The MDF7P-26DP-2.54DSA(95) qualifies as a direct substitute, sharing identical electrical and mechanical specifications while maintaining active product status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MDF7P-26DP-2.54DSA(95) is the qualified substitute for the obsolete MDF7P-26DP-2.54DSA(55). Both parts maintain identical electrical and mechanical specifications across all critical parameters.

The packaging difference between the two variants does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between MDF7P-26DP-2.54DSA(55) and MDF7P-26DP-2.54DSA(95)?

A: The primary difference is product status and packaging. The (55) variant is obsolete, while the (95) variant is active. The (95) is supplied in bag packaging, whereas the (55) packaging specification is not provided. All electrical and mechanical specifications are identical.

Q: Are these connectors mechanically interchangeable?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), row configuration (2 rows, 26 positions), contact geometry, and mounting type (through-hole solder termination). They are mechanically interchangeable in PCB designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS Compliant and carry UL94 V-0 material flammability rating. Both support identical operating temperature ranges (-35°C ~ 85°C) and current/voltage ratings (3A, 250V).

Q: Why should I select the MDF7P-26DP-2.54DSA(95) over the (55)?

A: The (95) variant is the active product, ensuring reliable procurement and supply chain continuity. The obsolete (55) variant may face availability constraints and should be replaced in new designs.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance, contact resistance characteristics, and mechanical durability within the specified operating parameters.
