• Connector Series: MDF7 (same manufacturer family)
• Number of Positions: 5 positions
• Pitch: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 3A
• Voltage Rating: 250V
• Operating Temperature Range: -35°C ~ 85°C
• Material Compliance: RoHS Compliant, UL94 V-0

The identified substitute part MDF7-5P-2.54DSA(95) maintains all critical electrical and mechanical parameters required for functional equivalence. The primary distinction lies in product status and application style classification.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-5P-2.54DSA(95) serves as a direct functional equivalent to the obsolete MDF7-5P-2.54DSA(55). Both components share identical electrical ratings, mechanical dimensions, and material specifications. The substitute part is currently in active production status with confirmed inventory availability (1015 pcs), providing supply continuity for applications previously using the MDF7-5P-2.54DSA(55).

The primary difference between these parts is application style classification: the original part is designated for board-to-board connections, while the substitute is classified for board-to-cable/wire applications. This distinction does not affect electrical or mechanical compatibility when used in through-hole mounting configurations with identical pitch and contact specifications.

Both parts maintain RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory alignment for current design requirements.

Frequently Asked Questions (FAQ)

Q: Can MDF7-5P-2.54DSA(95) be used as a direct replacement for MDF7-5P-2.54DSA(55)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions (5 positions at 2.54mm pitch), contact specifications, and material composition. The substitute part is currently in active production.

Q: What is the difference between "Board to Board" and "Board to Cable/Wire" style classifications?

A: Style classification indicates the intended mating application. Board-to-board connectors typically mate with receptacle connectors on another PCB. Board-to-cable/wire connectors typically mate with wire harnesses or cable assemblies. Both MDF7 series parts use identical header pin configurations and are compatible with standard 2.54mm pitch receptacles.

Q: Are the voltage ratings equivalent between 250V and 250VAC?

A: Yes. The 250VAC specification for the substitute part indicates AC voltage rating, while the original part specifies 250V. Both ratings are equivalent for this connector category and application context.

Q: What is the current inventory status for the substitute part?

A: MDF7-5P-2.54DSA(95) has 1015 pcs available as new original stock.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability certification, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Are there any thermal or environmental operating differences?

A: No. Both parts operate across the identical temperature range of -35°C to 85°C and share MSL 1 (Unlimited) moisture sensitivity classification.
