Engineering Selection Recommendations

The XF3M-1815-1B is a direct parametric equivalent to the XF3M18151B. Both connectors share identical electrical, mechanical, and dimensional specifications within the XF3M series.

The primary distinction is product status: XF3M18151B is obsolete, while XF3M-1815-1B is active. The substitute part carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

For new designs or ongoing production requiring the XF3M18151B specification, XF3M-1815-1B is the appropriate selection. The active status and RoHS compliance of the substitute part ensure long-term supply chain viability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can XF3M-1815-1B be used as a direct replacement for XF3M18151B?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and dimensional specifications. They share identical pitch (0.5mm), position count (18), mounting configuration (surface mount, right angle), voltage rating (50V), current rating (0.5A), operating temperature range (-30°C to 85°C), and locking mechanisms (rotary lock with backlock).

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

A: The primary differences are product status and packaging. XF3M18151B is obsolete with unspecified packaging, while XF3M-1815-1B is active and supplied in Tape & Reel (TR) format. XF3M-1815-1B also carries RoHS compliance certification.

Q: Are there any compatibility concerns when substituting XF3M-1815-1B for XF3M18151B?

A: No compatibility concerns exist. The connectors are mechanically and electrically interchangeable. Both feature identical contact materials (copper alloy with gold finish), housing materials (halogen-free LCP), and mechanical retention features (solder retention with rotary lock and backlock).

Q: Does packaging format affect the substitution?

A: Packaging format does not affect connector performance or compatibility. XF3M-1815-1B is supplied in Tape & Reel format, which is standard for production environments. This format does not impact electrical or mechanical function.

Q: Is RoHS compliance a requirement for substitution?

A: RoHS compliance is not a substitution requirement but represents a regulatory advantage. XF3M-1815-1B's RoHS compliance ensures compliance with current environmental and regulatory standards, making it the preferred choice for new applications and ongoing production.
