Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0878910751 are qualified based on the following critical parameters that must remain constant:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 7
• Number of Rows: 1
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Style: Board to Board or Cable
• Shrouding: Unshrouded
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

The identified substitute parts are TE Connectivity AMP Connectors models 87220-7 and 87224-7, both from the AMPMODU Mod II series. These parts maintain all critical mechanical and electrical compatibility parameters with the main part while offering alternative contact finishes and material compositions.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain full mechanical and electrical compatibility with the Molex 0878910751 across all critical parameters. Selection between the main part and substitutes should be based on the following factors:

TE Connectivity 87220-7 is an active production part with RoHS compliance status and higher inventory availability (3713 units). This part features gold-plated contacts with 30.0µin thickness and phosphor bronze contact material, offering enhanced corrosion resistance compared to the tin-plated copper alloy contacts of the main part.

TE Connectivity 87224-7 is an active production part with lower inventory (728 units) and non-applicable RoHS status. This part features gold-plated contacts with 15.0µin thickness and phosphor bronze contact material, providing a thinner gold finish alternative.

The Molex 0878910751 remains the primary specification with ROHS3 compliance and established supply chain presence (1048 units in stock). All three parts share identical mechanical dimensions, pitch, position count, and fastening characteristics, ensuring direct functional interchangeability in board-to-board and cable applications.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 87220-7 and 87224-7 be used interchangeably with Molex 0878910751?

A: Yes. All three parts maintain identical pitch (0.100"), position count (7), contact type (male pin), mounting method (through hole), and termination (solder). The primary differences are contact finish thickness and material composition, which do not affect mechanical compatibility or basic electrical function in standard applications.

Q: What are the differences in contact finish between these parts?

A: The Molex 0878910751 features tin-plated copper alloy contacts. The TE Connectivity 87220-7 provides gold plating at 30.0µin thickness on phosphor bronze. The TE Connectivity 87224-7 provides gold plating at 15.0µin thickness on phosphor bronze. Gold finishes offer superior corrosion resistance in high-humidity or corrosive environments.

Q: Are there packaging differences between these parts?

A: Yes. The Molex 0878910751 is supplied in trays, while both TE Connectivity substitutes are supplied in bulk packaging. Packaging format does not affect connector function or compatibility.

Q: Which part should be selected for new designs?

A: Selection should be based on application requirements, supply chain availability, and compliance mandates. The Molex 0878910751 offers ROHS3 compliance and established supply. The TE Connectivity 87220-7 offers RoHS compliance with higher inventory and gold-plated contacts. The TE Connectivity 87224-7 offers an alternative with thinner gold plating and non-applicable RoHS status.

Q: Do these parts have specified operating temperature ranges?

A: The Molex 0878910751 does not specify an operating temperature range in the provided data. Both TE Connectivity substitutes specify -65°C to 105°C operating temperature. Application requirements should determine if this specification is necessary for part selection.

Q: What is the current rating for these connectors?

A: The Molex 0878910751 does not specify a current rating. Both TE Connectivity substitutes specify 3A current rating per contact. Application current requirements should be evaluated against the 3A specification of the substitute parts.
