Substitute Part Grouping Explanation

The MDF7C-3P-2.54DSA(55) has one identified substitute within the MDF7 series: MDF7C-3P-2.54DSA(95). Substitution eligibility is determined by the following critical parameters:

• Number of positions: 3
• Pitch spacing: 0.100" (2.54mm)
• Number of rows: 1
• Mounting type: Through hole
• Termination method: Solder
• Contact finish: Tin
• Series designation: MDF7
• Current rating: 3A
• Voltage rating: 250VAC
• RoHS compliance: Yes

The substitute part maintains identical electrical and mechanical specifications across all critical dimensions and performance ratings. The primary distinction is product status: the substitute is active production, whereas the main part is obsolete.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can MDF7C-3P-2.54DSA(95) be used as a direct replacement for MDF7C-3P-2.54DSA(55)?

A: Yes. Both parts are identical in electrical rating (3A, 250VAC), mechanical dimensions (0.100" pitch, 3 positions, 1 row), mounting type (through hole), and contact finish (tin). The substitute is the active production equivalent of the obsolete part.

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

A: The primary difference is product status. MDF7C-3P-2.54DSA(55) is obsolete, while MDF7C-3P-2.54DSA(95) is in active production. All functional and dimensional specifications are equivalent.

Q: Are there any packaging differences?

A: The substitute part is supplied in bag packaging. Packaging format does not affect connector functionality or compatibility.

Q: Do both parts meet RoHS requirements?

A: Yes. Both MDF7C-3P-2.54DSA(55) and MDF7C-3P-2.54DSA(95) are RoHS compliant with MSL Level 1 classification.

Q: What are the critical parameters for substitution compatibility?

A: Substitution is valid when the following parameters match: number of positions (3), pitch spacing (0.100" / 2.54mm), number of rows (1), mounting type (through hole), termination method (solder), and contact finish (tin). Both parts satisfy these requirements.

Q: Is the operating temperature range specified for both parts?

A: The substitute part specifies -35°C to 85°C operating temperature. This range is typical for this connector class and supports standard industrial applications.
