Key Parameters

Substitute Part Grouping Explanation

The 87409-110LF qualifies as a direct substitute for the 87409-110 based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type, Contact Type, and Position Configuration: Both parts are male pin headers with identical 20-position, 2-row layouts
• Pitch and Row Spacing: Both maintain 0.050" (1.27mm) mating pitch and row spacing, ensuring mechanical interchangeability
• Mounting and Shrouding: Both are surface mount with identical shrouded 4-wall construction and push-pull fastening
• Operating Temperature Range: Both support -55°C to 130°C operation
• Insulation Material and Flammability: Both use thermoplastic glass-filled insulation with UL94 V-0 rating
• Mated Stacking Height: Both specify 6.42mm stacking height

The primary differences between these parts relate to compliance certifications and contact finish specifications, which do not affect mechanical or electrical interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

87409-110: Select this part number for applications where RoHS compliance is not a requirement and tin-lead post finish is acceptable. This part maintains active production status and is suitable for legacy designs and general purpose applications.

87409-110LF: Select this part number for new designs and applications requiring RoHS compliance. The "LF" designation indicates lead-free construction with tin post finish instead of tin-lead. This part is RoHS compliant and REACH affected, making it the preferred choice for modern product development and regulated markets. Both parts share identical mechanical and electrical characteristics, ensuring direct substitution capability.

Frequently Asked Questions (FAQ)

Q: Are the 87409-110 and 87409-110LF mechanically interchangeable?

A: Yes. Both parts maintain identical pitch (0.050" / 1.27mm), row spacing, position count (20 positions, 2 rows), mounting type (surface mount), shrouding (4-wall), and mated stacking height (6.42mm). They are mechanically interchangeable in board-to-board applications.

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

A: The primary difference is RoHS compliance status and post contact finish. The 87409-110 uses tin-lead finish and is RoHS non-compliant. The 87409-110LF uses lead-free tin finish and is RoHS compliant with REACH applicability.

Q: Can I substitute 87409-110LF for 87409-110 in existing designs?

A: Yes, the 87409-110LF is a direct substitute for the 87409-110. Both parts share identical mechanical dimensions, electrical characteristics, and operating temperature ranges (-55°C to 130°C). The substitution is valid for all applications where the original part was used.

Q: Which part should I specify for new product designs?

A: Specify 87409-110LF for new designs. This part is RoHS compliant and lead-free, aligning with current regulatory requirements and industry standards for electronic components.

Q: Are there any soldering process differences between these parts?

A: Both parts use solder termination and are compatible with standard surface mount assembly processes. The lead-free tin finish of the 87409-110LF may require slightly higher reflow temperatures compared to tin-lead finishes, but both parts operate within standard SMT process windows.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity concerns. These parts can be stored and handled without special moisture control measures.
