Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL-109-T-32 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 9 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Electrical & Environmental Specifications: Gold mating contact finish at 30.0µin thickness, operating range -55°C to 125°C
• Material & Compliance: Liquid Crystal Polymer insulation, ROHS3 compliance, MSL 1 rating

The substitute part SL-109-G-39 meets all critical substitution criteria. Both parts share the same base product number (SL-109), connector topology, and core electrical specifications. The primary distinction lies in post-contact finish specifications, which do not affect mating interface compatibility or functional performance in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both SL-109-T-32 and SL-109-G-39 are Active product status connectors manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on:

Inventory Availability: SL-109-G-39 currently maintains higher stock levels (1136 pcs) compared to SL-109-T-32 (754 pcs), making it suitable for applications where supply continuity is a priority.

Compliance & Certification: Both parts carry identical regulatory certifications (ROHS3, MSL 1, EAR99 ECCN classification). SL-109-G-39 includes documented REACH Affected status, providing additional regulatory transparency for applications subject to REACH requirements.

Functional Equivalence: The mating interface specifications are identical across both parts. Post-contact finish differences do not impact board-to-board mating performance or electrical characteristics in standard applications.

Frequently Asked Questions (FAQ)

Q: Can SL-109-G-39 be used as a direct replacement for SL-109-T-32 in existing designs?

A: Yes. Both connectors share identical mating interface specifications, pitch, position count, mounting type, and operating temperature range. The connectors are functionally equivalent for board-to-board applications.

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

A: The primary difference is the post-contact finish specification. SL-109-T-32 does not specify post-contact finish, while SL-109-G-39 specifies gold plating at 10.0µin (0.25µm) on post contacts. This difference does not affect mating interface compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both SL-109-T-32 and SL-109-G-39 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain requirements. Both parts are Active status and functionally equivalent. SL-109-G-39 offers higher current stock availability and documented REACH compliance status.

Q: Are there any mechanical or electrical differences between these connectors?

A: No. Both connectors feature identical mechanical dimensions, contact materials (Beryllium Copper), insulation material (Liquid Crystal Polymer), and electrical operating specifications.
