Parameter Comparison

Engineering Selection Recommendations

WR-PHD 62301421021 (Primary Part):

• Active product status with established supply chain
• ROHS3 compliant and REACH unaffected
• MSL 1 rating supports standard storage and handling
• Suitable for applications within -40°C to 105°C operating range
• Current rating of 1A per contact meets standard low-power board-to-board applications

SFMC-107-02-S-D (Substitute Part):

• Active product status with confirmed inventory availability
• ROHS3 compliant and REACH unaffected
• MSL 1 rating supports standard storage and handling
• Extended operating temperature range (-55°C to 125°C) provides thermal margin beyond primary part specification
• Current rating of 2.9A per contact exceeds primary part specification, supporting higher-power applications
• Beryllium copper contact material and liquid crystal polymer insulation provide alternative material composition
• Compatible with board-to-board or cable configurations, offering application flexibility

Both parts satisfy identical mechanical pitch, position count, row configuration, and fastening requirements. Selection between primary and substitute parts depends on application-specific thermal and current requirements within the stated operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the SFMC-107-02-S-D directly replace the WR-PHD 62301421021 in existing designs?

A: Yes. Both connectors share identical mechanical pitch (0.050"), position count (14), row configuration (2 rows at 0.050" spacing), mounting type (surface mount), termination method (solder), and fastening mechanism (push-pull). Footprint compatibility is established through these matching parameters.

Q: What are the key differences between these two connectors?

A: The primary differences are contact material composition (copper alloy versus beryllium copper), insulation material (polyamide versus liquid crystal polymer), current rating (1A versus 2.9A per contact), and operating temperature range (-40°C to 105°C versus -55°C to 125°C). The SFMC-107-02-S-D provides higher current capacity and extended thermal operating range.

Q: Are both parts compliant with industry standards?

A: Yes. Both the WR-PHD 62301421021 and SFMC-107-02-S-D are ROHS3 compliant, REACH unaffected, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: Which part should be selected for high-temperature applications?

A: The SFMC-107-02-S-D supports operation to 125°C, exceeding the WR-PHD 62301421021 maximum of 105°C. For applications requiring sustained operation above 105°C, the SFMC-107-02-S-D is the appropriate selection.

Q: Which part should be selected for high-current applications?

A: The SFMC-107-02-S-D is rated for 2.9A per contact, compared to 1A for the WR-PHD 62301421021. For applications requiring current capacity above 1A per contact, the SFMC-107-02-S-D is the appropriate selection.

Q: Are there packaging differences between these connectors?

A: Both parts are supplied in tube packaging. Inventory availability differs: WR-PHD 62301421021 has 1198 pieces in stock, while SFMC-107-02-S-D has 887 pieces in stock.

Q: What is the voltage rating for these connectors?

A: The WR-PHD 62301421021 is rated for 100VAC. The SFMC-107-02-S-D voltage rating is not specified in the provided parameters.

Q: Can the SFMC-107-02-S-D be used in cable-to-board applications?

A: The SFMC-107-02-S-D supports both board-to-board and cable configurations. The WR-PHD 62301421021 is specified for board-to-board style only. This provides additional application flexibility with the substitute part.
