Key Parameters

Substitute Part Grouping Explanation

The SMM-115-02-S-D qualifies as a manufacturer-recommended substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 30
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Surface mount
• Fastening type: Push-pull
• Operating temperature: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Insulation material: Liquid Crystal Polymer (LCP)
• Contact shape: Square
• RoHS status: ROHS3 compliant
• Moisture sensitivity level: 1 (Unlimited)

These parameters define the mechanical and electrical interface compatibility required for direct substitution in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both CLT-115-02-L-D-P and SMM-115-02-S-D maintain active product status and ROHS3 compliance with identical MSL 1 ratings. The connectors share identical mechanical interfaces, pitch specifications, and operating temperature ranges, establishing direct substitution capability.

Differences in contact material (phosphor bronze versus beryllium copper), contact finish thickness (10.0µin versus 30.0µin), current rating (4.1A versus 3.2A per contact), and voltage rating (unspecified versus 350VAC) represent design variations within the same functional category. Selection between these parts depends on application-specific current and voltage requirements. The SMM-115-02-S-D provides higher contact finish thickness and specified voltage rating, while the CLT-115-02-L-D-P offers higher current capacity per contact.

Frequently Asked Questions (FAQ)

Q: Can SMM-115-02-S-D directly replace CLT-115-02-L-D-P in existing designs?

A: Yes. Both connectors share identical pitch (0.079"), position count (30), row configuration (2 rows), mounting type (surface mount), and fastening mechanism (push-pull). The mechanical and electrical interfaces are compatible for board-to-board applications.

Q: What are the differences in contact specifications?

A: The CLT-115-02-L-D-P uses phosphor bronze contacts with 10.0µin gold plating and supports 4.1A per contact. The SMM-115-02-S-D uses beryllium copper contacts with 30.0µin gold plating, supports 3.2A per contact, and specifies 350VAC rating. Applications requiring current above 3.2A per contact should use CLT-115-02-L-D-P.

Q: Are packaging differences significant for component selection?

A: CLT-115-02-L-D-P ships in tube packaging while SMM-115-02-S-D ships in bulk packaging. This affects handling and storage procedures but does not impact electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity level.
