Key Parameters

Substitute Part Grouping Explanation

The 3M 10268-55H3PC qualifies as a direct substitute for the 10268-55H3VC based on the following alignment of critical parameters:

• Connector Type & Position Count: Both are 68-position receptacles with 2-row configuration
• Mounting & Termination: Both feature panel mount, through-hole, right-angle solder termination
• Series & Style: Both belong to the 3M 102 Mini D Ribbon (MDR) series with outer shroud contacts
• Electrical & Mechanical Features: Both include board lock, shielded design, and identical flange specifications (Housing/Shell 4-40 with latchblocks)
• Contact Specifications: Both utilize gold-plated contacts with 30.0µin (0.76µm) finish thickness

The primary distinction between these parts is product status and packaging configuration, not functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 3M 10268-55H3PC is the appropriate selection for applications currently specified for the 10268-55H3VC. The substitute part maintains full electrical and mechanical compatibility across all functional parameters.

The 10268-55H3PC offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The part is RoHS compliant, meeting modern regulatory requirements for new designs and manufacturing environments where RoHS compliance is mandated.

Both parts share identical moisture sensitivity classification (MSL 1), export control designation (EAR99), and tariff classification (HTSUS 8536.69.4040), eliminating compliance or logistics complications during substitution.

Frequently Asked Questions (FAQ)

Q: Are the 10268-55H3VC and 10268-55H3PC mechanically interchangeable?

A: Yes. Both connectors feature identical mounting configurations (panel mount, through-hole, right-angle), flange specifications (Housing/Shell 4-40 with latchblocks), and contact arrangements (68 positions, 2 rows). They mount identically on circuit boards and panels.

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

A: The primary differences are product status and packaging. The 10268-55H3VC is obsolete, while the 10268-55H3PC is active. The 10268-55H3PC is supplied in bulk packaging. The 10268-55H3PC is RoHS compliant; the 10268-55H3VC is not.

Q: Can the 10268-55H3PC be used in applications originally designed for the 10268-55H3VC?

A: Yes. All electrical and mechanical parameters are identical. The connector type, position count, mounting method, termination style, series designation, shielding, board lock feature, and contact finish specifications are equivalent.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance indicates the material composition meets regulatory standards but does not alter the connector's electrical or mechanical function. The 10268-55H3PC's RoHS compliance makes it suitable for applications with regulatory requirements while maintaining full compatibility with the original design.

Q: Are there any packaging considerations when substituting these parts?

A: The 10268-55H3PC is supplied in bulk packaging, whereas the 10268-55H3VC packaging type was not specified. Verify bulk packaging meets your procurement and handling requirements.
