Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDL-122-T-10 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (44)
• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows with 0.100" row spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish (Gold at 30.0µin thickness)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

Parts meeting all these specifications are classified as direct equivalents. The SDL-122-T-10 is identified as its own equivalent based on the provided substitute list.

Parameter Comparison

Engineering Selection Recommendations

The SDL-122-T-10 is an active production component with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. The part carries MSL 1 rating, indicating unlimited shelf life without moisture sensitivity constraints. Selection of equivalent parts should prioritize components with identical active product status and matching compliance certifications to ensure supply chain continuity and regulatory alignment. The through-hole solder termination and push-pull fastening mechanism provide robust mechanical retention suitable for high-reliability board-to-board interconnection applications.

Frequently Asked Questions (FAQ)

Q: What makes a part equivalent to the SDL-122-T-10?

A: A part is equivalent when it matches all critical specifications: 44-position receptacle configuration, 0.100" pitch spacing in a 2-row arrangement, female socket contacts with gold plating at 30.0µin thickness, through-hole solder termination, push-pull fastening, Liquid Crystal Polymer insulation, and operating temperature range of -55°C to 125°C.

Q: Can I use a different pitch spacing connector as a substitute?

A: No. The 0.100" (2.54mm) pitch spacing is a fundamental mechanical specification. Connectors with different pitch spacing will not mate with the corresponding plug connector and cannot be substituted.

Q: Does the number of rows affect substitution compatibility?

A: Yes. The SDL-122-T-10 is configured as a 2-row connector with 0.100" row spacing. Any substitute must maintain this exact row configuration and spacing to ensure proper mating and electrical continuity.

Q: What is the significance of the gold contact finish thickness specification?

A: The 30.0µin (0.76µm) gold plating thickness is specified to ensure consistent contact resistance, corrosion resistance, and long-term reliability. Substitute parts must match this thickness to maintain equivalent electrical performance.

Q: Are there any packaging considerations for this connector?

A: The SDL-122-T-10 is supplied in tube packaging. When sourcing equivalent parts, confirm packaging format matches your assembly and handling requirements, as this affects component presentation and automated placement compatibility.

Q: What does ROHS3 compliance mean for this connector?

A: ROHS3 compliance indicates the connector meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. This certification is mandatory for components used in European markets and many other regulated regions.

Q: Is the MSL 1 rating important for storage?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture sensitivity constraints. This connector does not require special dry storage conditions or baking procedures prior to assembly, simplifying inventory management.
