Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7B-6P-2.54DSA(55) is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (6)
• Pitch specification (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (3A minimum)
• Voltage rating (250V minimum)
• Operating temperature range (-35°C ~ 85°C)
• Material compliance (UL94 V-0, RoHS Compliant)

The substitute part MDF7B-6P-2.54DSA(95) maintains all critical electrical and mechanical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MDF7B-6P-2.54DSA(95) is the direct substitute for the obsolete MDF7B-6P-2.54DSA(55). Both parts are manufactured by Hirose Electric and belong to the same MDF7 series. The substitute maintains identical electrical specifications (3A current rating, 250V voltage rating), mechanical dimensions, contact configuration, and material compliance (UL94 V-0, RoHS Compliant).

The primary distinction is product status: the main part is obsolete while the substitute is active. The substitute offers superior availability with 1080 pieces in stock compared to 694 pieces for the obsolete variant. Both parts operate across the identical temperature range (-35°C ~ 85°C) and share equivalent contact geometry and termination characteristics.

Frequently Asked Questions (FAQ)

Q: Can MDF7B-6P-2.54DSA(95) directly replace MDF7B-6P-2.54DSA(55)?

A: Yes. Both parts share identical connector type, contact configuration, pitch specification, mounting method, and electrical ratings. The substitute is the active production equivalent.

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

A: The suffix designation (55 versus 95) indicates packaging and product lifecycle status. The (55) variant is obsolete; the (95) variant is active production with bag packaging.

Q: Are the physical dimensions compatible?

A: Yes. Overall contact length differs by 0.01mm (0.867" versus 0.866"), which is within manufacturing tolerance and does not affect mechanical compatibility or board-level integration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS Compliant and carry UL94 V-0 material flammability rating. Moisture Sensitivity Level is 1 (Unlimited) for both variants.

Q: What is the voltage rating specification?

A: The main part specifies 250V; the substitute specifies 250VAC. Both are suitable for the same application voltage requirements.

Q: Are there any application differences between board-to-board and board-to-cable configurations?

A: The main part is specified for board-to-board style; the substitute is specified for board-to-cable/wire style. Both use identical header connector type and male pin contacts with solder termination, maintaining functional compatibility in standard through-hole applications.
