Key Parameters

Substitute Part Grouping Explanation

Substitution for the SDL-118-G-12 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (36)
• 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 specifications (Gold plating on mating and post surfaces)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

Only parts matching all these parameters qualify as direct equivalents or substitutes for the SDL-118-G-12.

Parameter Comparison

Engineering Selection Recommendations

The SDL-118-G-12 is an active product with full ROHS3 compliance and REACH unaffected status, making it suitable for current production applications. The part carries MSL Level 1 (Unlimited) moisture sensitivity, indicating no special storage or handling requirements beyond standard component practices.

Selection of equivalent parts should be based on exact parameter matching as outlined in the parameter comparison table. The active product status and compliance certifications ensure long-term availability and regulatory alignment for new designs and production environments.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct equivalent to the SDL-118-G-12?

A: A direct equivalent must match all critical specifications: 36-position receptacle configuration, 0.100" pitch spacing, 2-row layout with 0.100" row spacing, through-hole solder termination, push-pull fastening, gold contact finish, beryllium copper contacts, LCP 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 is a critical mechanical parameter. Connectors with different pitch spacing will not mate correctly with mating plugs or headers designed for the SDL-118-G-12.

Q: Does the contact finish thickness affect substitution eligibility?

A: Yes. The specified gold plating thickness of 30.0µin (0.76µm) on mating surfaces and 10.0µin (0.25µm) on post surfaces are part of the electrical and reliability specifications. Parts with different plating thicknesses are not direct equivalents.

Q: Is the insulation material critical for substitution?

A: Yes. The Liquid Crystal Polymer (LCP) insulation material is specified for its mechanical and thermal properties. Substitutes must use the same insulation material to maintain dimensional stability and performance across the operating temperature range.

Q: What is the significance of the MSL Level 1 rating?

A: MSL Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.

Q: Are there any compliance considerations for selecting substitutes?

A: Yes. Both the main part and any substitute must maintain ROHS3 compliance and REACH unaffected status to meet regulatory requirements in target markets.
